Motion: Adopt the Resolution. Synopsis of Previous Council Action: 05/07/2012 Resolution No. 2012-078 was adopted, approving a Storm Drain Development Impact Fee Prepayment Agreement with the Inland Valley Development Agency (IVDA). 04/20/2015 Resolution No. 2015-078 was adopted, approving Amendment No. 1 to a Storm Drain Development Impact Fee Prepayment Agreement with the Inland Valley Development Agency (IVDA). Background: The Inland Valley Development Agency (IVDA) is proposing to construct a Master Plan Storm Drain in Orange Show Road between Lena Road and Twin Creek. The proposed Twin Creek Orange Show Road Storm Drain Project (PWP No. 15-01) is located within the City's right-of-way for Orange Show Road from Twin Creek west to Lena Road, and in Lena Road 575 feet north of Norman Road, a total distance of approximately 1.0 mile. The entire flood control improvement project is within the City Limits of the City of San Bernardino (see attached Project Location Map). This storm drain project is being funded and constructed entirely by IVDA to provide flood protection for development projects in the areas controlled by IVDA. Under terms of a Storm Drain Development Impact Fee Prepayment Agreement between IVDA and the City, upon completion of construction of the storm drain, IVDA will be afforded a credit in the approximate amount of $1,400,000 against Storm Drain Impact Fees due or to become due for projects they are developing in the area. Updated: 6/10/2015 by Georgeann "Gigi" Hanna B Packet Pg.216 3803 On March 26, 2015, the Environmental and Development Review Committee (E/DRC) reviewed the Initial Study and recommended that the Initial Study be released for Public Review and that the Project be moved to the Mayor and Common Council with a recommendation to adopt a Mitigated Negative Declaration (MND). The Initial Study is attached as Exhibit "A." All project impacts are being mitigated to a "Less-than- Significant" level. Also attached is a Mitigation Monitoring and Reporting Program (Exhibit "B"). This document is required to be signed off by City inspectors, as the work progresses to insure that all mitigation measures are completed during construction. The Public Review period began on April 2, 2015, and was completed on May 2, 2015. The California Department of Fish and Wildlife (CDFW) commented in a letter to the City dated April 30, 2015 (See Attachment 1). CDFW's comments were reviewed by LSA Associates on behalf of the City and, in a Memorandum dated May 6, 2015 to Aron Liang, Senior Planner, stated that the mitigation measures currently provided in the Initial Study/Mitigated Negative Declaration (IS/MND) for the Twin Creek Orange Show Road Storm Drain Project adequately addresses potential project Impacts to biological resources. With measures provided in the IS/MND, project impacts to biological resources will be less than significant. Additional biological surveys and changes to the biological resources section of the IS/MND are not necessary (See Attachment 2). No other comments were received during the public review period. The construction start date has not yet been determined; however, construction will require about four (4) months to complete. To assure minimal disruption of traffic on Orange Show Road during construction, the developer will be required to submit a "Construction Traffic Mitigation Plan" to the City for review and approval prior to starting work. Staff recommends that the Mayor and Common Council review the Initial Study (Exhibit "A"), adopt a Mitigated Negative Declaration for this Project and approve the Mitigation Monitoring and Reporting Program (Exhibit "B") and authorize the filing of a Notice of Determination (NOD) with the Clerk of the Board of Supervisors of San Bernardino County.

The proposed Project is located ;Z within the Orange Show Road from the Twin Creek Flood Control Channel east to Lena Road, and in Lena Road north to 575 feet north of Norman Road, a distance of 0 approximately 1.0 mile, in the City of San Bernardino, California. Twin Creek has its confluence with the Santa Ana River 3,500 feet south of this Project. M 0 The City of San Bernardino (City) operates the drainage system infrastructure within its M boundaries. The existing system is a 36" reinforced concrete pipe (RCP) which LO discharges 92 cubic feet per second (cfs) into Twin Creek. The City is proposing to 6 replace the existing storm drain to increase capacity and serve the design flow of proposed developments in the area. The design flow for this Project is the 100 year ° storm event and the ultimate downstream design flow for this Project is 1,275.9 cfs. E California Environmental Quality Act (CEQA) Role E 0 U CDFW has jurisdiction over the conservation, protection, and management of fish, � wildlife, native plants, and the habitat necessary for biologically sustainable populations of those species (i.e., biological resources). CDFW is a Trustee Agency with responsibility under CEQA for commenting on projects that could affect biological resources. As a Trustee Agency, the Department is responsible for providing, as available, biological expertise to review and comment upon environmental documents and impacts arising from project activities (CEQA Guidelines, § 15386; Fish & G. Code, a § 1802). _ E v m Q Conserving Cal forma's Wi(d[fe Since 1870 Packet Pg.219 ATTACHMENT 1 Mitigated Negative Declaration Twin Creek Orange Show Road Storm Drain Project Page 2 of 4 0 L CDFW also acts as a Responsible Agency based on its discretionary authority regarding project activities that impact streams and lakes (Fish & G. Code, §§ 1600 -- 1616), in this case Twin Creek, or result in the "take" of any species listed as candidate, °� threatened, or endangered pursuant to the California Endangered Species Act (CESA; o Fish & G. Code, § 2050 et seq.). in CDFW will be acting as both a Trustee and Responsible Agency for this project. 0 Comments and Recommendations_ Cn a) CDFW offers the comments and recommendations presented below to assist the City in adequately identifying and/or mitigating the project's significant, or potentially significant, 2 impacts on biological resources. These comments and recommendations are based on Y the requirement for the environmental document to provide a description of feasible 2 mitigation measures to avoid potentially significant impacts, and/or mitigate significant U impacts, of the proposed project on the environment(CEQA Guidelines, §§ 15021, 3 15063, 15071, 15126.2, 15126.4& 15370). L 0 4- Nesting Birds and Migratory Treaty Act Please note that it is the project proponent's responsibility to comply with all applicable z laws related to nesting birds and birds of prey. Migratory non-game native bird species are protected by international treaty under the federal Migratory Bird Treaty Act (MBTA) Q of 1918, as amended (16 U.S.C. 703 et seq.). In addition, sections 3503, 3503.5, and o 3513 of the Fish and Game Code (FGC) stipulate the following: Section 3503 states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by FGC or any regulation made pursuant thereto; Section 3503.5 co states that it is unlawful to take, possess, or destroy any birds in the orders M Falconiformes or Stdgiformes (birds-of-prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by FGC or any regulation adopted M pursuant thereto; and Section 3513 states that it is unlawful to take or possess any � migratory nongame bird as designated in the MBTA or any part of such migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the MBTA. E 0 The IS states that suitable habitat for burrowing owl is present within the Project alignment but that no sign of burrowing owl was found on site. BIO-1 states that "a pre- o construction burrowing owl survey shall be conducted within 10 days prior to beginning of site grading in the event that burrowing owls occupy the site in the future", and will J reflect the standards of CDFW's 2012 Staff Report on Burrowing Owl Mitigation. Because surveys have not yet been conducted, the IS/MND does not provide enough information about the potential impacts to burrowing owl nesting and/or foraging habitat for CDFW to determine whether impacts would be mitigated. The 2012 Staff Report d ® specifies that the steps for project impact evaluations include: a. A habitat assessment; U b. Surveys; and ED a Packet Pg.no ATTACHMENT 1 Mitigated Negative Declaration Twin Creek Orange Show Road Storm Drain Project Page 3 of 4 0 L c. An impact assessment. - L As stated in the Staff Report, the three progressive steps are effective in evaluating ° whether a project will result in impacts to burrowing owls, and the information gained E 0 from the steps will inform any subsequent avoidance, minimization, and mitigation measures. CDFW recommends that focused surveys for burrowing owl be conducted 1 over all potential suitable habitat within the entire project site. The burrowing owl is protected under the MBTA and Sections 3503, 3503.5, and 3513 of the FGC; therefore, 3 it is the responsibility of the project proponent to ensure compliance with these laws for the entire project site. CDFW requests that the City complete burrowing owl surveys of the project site and provide the results of these surveys in a recirculated MND. Because the MND fails to provide the results of burrowing owl surveys, CDFW is unable to determine whether impacts to this species will be less-than-significant. CDFW also queries how the City was able to make a less-than-significant finding without the results of this survey. 1310-3 states that "if project activities are planned during the! avian nesting season 0 (approximately February 1 through August 31), nesting bird surveys shall be conducted — within three days prior to disturbance..." Because some species of raptors (e.g., owls) o may commence nesting activities in January, CDFW encourages the Lead Agency to complete nesting bird surveys regardless of time of year to ensure compliance with all Z applicable laws related to nesting birds and birds of prey. CDFW recommends that o surveys focus on all suitable nesting habitats within the project area, including the a ground. CDFW requests that the City revise BIO-3 and require an avian breeding 0 survey, regardless of time of year to ensure that the project complies with all federal, Q state, and local laws. co O 00 Lake and Streambed Alteration Program LO r The IS/MND states that a Notification of Lake and Streambed Alteration will be M submitted to CDFW, and BIO-2 proposes a minimum 1:1 mitigation ratio for o riparian/riverine habitat impacts in the Twin Creek channel, and 2:1 mitigation ratio for any residual onsite impacts. 1310-2 proposes to offset project impacts through the contribution of funds to the Inland Empire Conservation District. Please note that mitigation for permanent impacts must be sufficient to replace lost streambed habitat 0 functions and values, and as such CDFW may require higher levels of mitigation than the 1:1 and 2:1 mitigation ratios proposed in the IS/MND prior to issuance of an LSA o Agreement, if deemed necessary. Please also note that in order for CDFW to facilitate issuance of an LSA Agreement, the environmental document should fully identify the potential impacts to the lake, stream, or riparian resources and provide adequate avoidance, mitigation, and monitoring and reporting commitments. w Early consultation with CDFW is recommended, since modification of the proposed a project may be required to avoid or reduce impacts to fish and wildlife resources.

E L 0 *1 U) N0 W occurrences of burrowing owls were recorded within 3 miles of the study area.The vicinity surrounding the study area is developed and isolated from any large areas of suitable habitat that °_ would support breeding burrowing owls.As noted,the Twin Creek Channel is regularly cleared to of vegetation for flood control purposes.Additionally,project impacts within Twin Creek Channel will be short-term,and permanent loss of low-quality potential burrowing owl habitat will be less than 0.25 acre.Due to the low quality of habitat,a pre-construction survey will 0 adequately identify if burrowing owl occupy the proposed project area at the time of construction. Measure BIO-1 includes mitigation that will be implemented in the unlikely event that burrowing U owls or their sign are found within the project area at the time of the pre-construction survey. c Measure BIO-1 adequately ensures that project impacts to burrowing owl will be less than significant. L 0 w- CDFW Comment: BIO-3 states that"if project activities are planned during the avian nesting o season(approximately February 1 through August 31),nesting bird surveys shall be conducted within three days prior to disturbance..."Because some species of raptors(e.g.owls)may z commence nesting activities in January,CDFW encourages the Lead Agency to complete nesting a brid surveys regardless of time of year to ensure compliance with all applicable laws related to 0 nesting birds and birds of prey.CDFW recommends that surveys focus on all suitable nesting a habitats within the project area,including the ground.CDFW requests that the City revise BIO-3 °w and require an avian breeding survey,regardless of time of year to ensure that the project complies with all federal,state,and local laws. 0 00 Response:The applicant will comply with the requirements of the federal Migratory Bird Treaty Act.The project site does not provide high quality habitat likely to support potential nesting raptors(no tall trees,no large clusters of vegetation).Project activities will not result in trimming of trees or removal of vegetation other than ornamental vegetation within the existing Orange 9 Show Road right-of-way. Since the project is within an existing disturbed area,pre-construction ° surveys during the generally-accepted nesting season of February I through August 31 will adequately ensure that potential impacts to nesting birds are less than significant. E E CDFW Comment: The IS/MND states that a Notification of Lake and Streambed Alteration will ° U be submitted to CDFW,and BIO-2 proposes a minimum 1:1 mitigation ratio for riparian/riverine 0 habitat impacts in the Twin Creek Channel,and 2:1 mitigation ratio for any residual onsite N impacts.13I0-2 proposes to offset project impacts through the contribution of funds to the Inland o Empire Resource Conservation District.Please note that mitigation for permanent impacts must C be sufficient to replace lost streambed habitat functions and values,and as such CDFW may m require higher levels of mitigation than the 1:1 and 2:1 mitigation ratios proposed in the IS/MND Q prior to issuance of an LSA agreement, if deemed necessary.Please also not that in order to Cn CDFW to facilitate issuance of an LSA agreement,the environmental document should fully E identify the potential impacts to the lake,stream, or riparian resources and provide adequate E avoidance,mitigation,and monitoring and reporting requirements. N Response: Impacts to riparian/riverine resources and mitigation for such impacts will be addressed in detail through the Streambed Alteration Notification process and it is understood 0 that agreed-upon mitigation ratios differ from the minimum ratios discussed in the IS/MND. Based on the existing site conditions the 1:1 and 2:1 ratios suggested in the IS/MND are expected to adequately compensate for project impacts to these resources.It is also understood that early c� Q 5/6/15(RaTHE1401_Twin Creek Orange ShowUnitial Study\RTC Memo-CDFW 5-6-15.docx) 2 Packet Pg.224 ATTACHMENT 2 LSA ASSOCIAT&S, INC E L O r N tC O W consultation with CDFW will ensure that compensation is sufficient to ensure impacts to 3 riparian/riverine resources are less than significant.

Attach 6 additional sheets,if necessary): Tha Turin Creek Orange Cho_,,Road Storm Drain project is located in the City of San Bernardino, County of d San Bernardino,California.The project limits are bound by Twin Creek on the western downstream end and approximately 575 feet north of Norman Road within Lena Road on the eastern upstream end. Twin Creek � has its confluence with the Santa Ana River 3,500 feet(0.66 mile)south of this project.The project location 4 is shown in Figures 1 and 3,while the outfall structure and typical trench section are shown in Figures 2 and 4. In addition, an aerial photo of surrounding land uses is provided in Figure 5, and photographs of the x project alignment are provided in Figure 6. w c The City operates the drainage system infrastructure within its boundaries. The Twin Creek Orange Show Road storm drain system was originally constructed in 2002. The existing system is a 36" reinforced ' Also shown as South Valley View Avenue on some area maps Q Twin Creek Orange Show Road Storm Drain Project 2 Packet Pg.229 5 J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY U concrete pipe(RCP)which discharges 92 cubic feet per second(cfs) into Twin Creek,although it is unclear 0 what storm event this flow rate represents.The upstream end of the existing 36-inch drain line is just east of a- the railroad crossing near Amos Avenue,approximately 1,100 feet east of the Twin Creek channel _ L The City is proposing to replace the existing storm drain to increase capacity and serve the design flow of the proposed developments in the area. The design flow for this project is the 100 year storm event and the o ultimate downstream design flow for this project is 1,275.9 cfs. This proposed system will consist of reinforced concrete box (RCB) and RCP components. The proposed system will allow for a discharge of 1,276 cfs into Twin Creek. The proposed project is the expansion of the storm drain system in Orange Show 0 Road to increase capacity. The existing storm drain currently located in the Orange Show Road roadway 3 will be replaced with a 12' x 9' RCB storm. drain and a new outfall structure will be located at the same o location as the existing structure in Twin Creek. A concrete headwall and wing walls and grouted rip rap pad will be installed at the outfall structure to prevent channel erosion caused by high velocity flows (the m expected velocity at the downstream end of the outlet structure is approximately 5.3 feet per second). O The existing 36" RCP and outfall structure (5' by 13') will be replaced with a 12' by 9' RCB. A concrete Y headwall and wing walls will be constructed per Caltrans standard plan D-84. The total length of these structures will be 67 feet on the southern side of the RCB and 59 feet on the northern side of the RCB. U c The total area within the channel that will be disturbed is approximately 0.28 acre. The western opening of the outfall structure(the space between the 2 wing walls) will be 50 feet wide. An additional 69 feet on the northern side and 95 feet on the southern side will be a graded slope to join the rip rap.The western opening at the end of the rip rap will be 87 feet wide(this is between the end of the wing walls and where the work o joins the channel at the cut off wall). The wing walls will have return walls prior to the graded slope. The a) return walls will be 16 feet on the northern side and 18 feet on the southern side. A 0.21 acre, 4-foot deep z grouted rip rap pad will be placed at the outfall structure in order to prevent streambed erosion. I will Q, consist of half-ton rip rap within the headwall/wing wall structure and quarter-ton rip rap outside of the structure (1,355 cubic yards total for the structure). Additionally, 0.05 acre will be graded to allow for o positive drainage into the existing channel topography(see Figure 2). N d o! The project will continue headed easterly in Orange Show Road approximately 2,045 lineal feet with a 144" x 108"RCB,then 18 lineal feet of 144"x 96"RCB,then 488 lineal feet of 102"RCP,then 1,515 lineal feet 00 of 108" RCP. At this point the system turns heading north in Lena Road approximately 510 lineal feet of 102"RCP,then 575 lineal feet of 90"RCP. At this point,the proposed storm drain will join the existing 90" RCP. In the existing condition, the 90"RCP in Lena Road discharges into existing detention basins located r at the northwest corner of Lena Road and Norman Road. Once all downstream construction is complete,the N_ connection to these basins will be removed(see Figure 3 and Table A for a summary of pipe reaches). t° _ m a> rn X w Y _ E M U �Q Y Twin Creek Orange Show Road Storm Drain Project 3 Packet Pg.230.

O d) Create a new source of substantial light or El [� ® glare, which would adversely affect m daytime or nighttime views of the area? V c 3 Discussion L 0 w- La No Impact. The proposed project would result in the temporary excavation of approximately a mile of o public streets plus a small area of the east bank of the Twin Creek flood control channel adjacent to the Orange Show Road bridge. The City's General Plan Natural Resources and Conservation Element(City d (V40) z of San Bernardino, 2005) identifies the Kendall Ili]Is, San Bernardino Mountains, the hillsides adjacent to Arrowhead Springs, Lytle Creek Wash, East Twin Creeks Wash, the Santa Ana River, Badger o Canyon, Bailey Canyon, and Waterman Canyon as distinctive vistas. During construction,views along a portions of Orange Shaw Road and Lena Road will include construction equipment, earth mounds, etc. 0 These temporary activities are not expected to impact any scenic vistas. After completion, no project improvements will be visible to area residents or travelers and will not affect views onto or out of the project area. Therefore, the proposed project will not cause long-term adverse impacts on any scenic o vistas and no mitigation is required. M I.b No Impact. The project site or alignment consists of the Twin Creek flood control channel and approximately one mile of two public roadways. The project area is relatively flat and only the Twin U) Creek channel contains any native vegetation. There are no scenic resources or historic buildings located within the alignment.The project alignment is not located along a state scenic highway.' Public E views of the San Bernardino Mountains from Interstate 10(I-10)and Interstate 215 (1-21 5)would not be .a affected as these freeways are located out of the project area (1.14 miles south and 0.75 mile west, m respectively). The project would not significantly hinder views from the site or adjacent properties. For 2) these reasons, no impacts associated with scenic resources within a state scenic highway will occur and no mitigation is required. Q I.c Less than Significant Impact.Based on the City's General Plan Land Use Map,the property adjoining s the project alignment has zoning designations of Light Industrial (IL) and Office/Industrial Park(OIP) w along Waterman Avenue at Orange Show Road. There will be minor visual impacts in the project area where and when construction is occurring,which is expected to be 500 lineal feet of roadway per day or d E � ca (WWI City of San Bernardino General Plan,Figure C-1 "Scenic Highways/Routes,"The Planning Center,November 2005. Q Twin Creek Orange Show Road Storm Drain Project 14 Packet Pg.241 CITY OF SAN BERNARDINO 0- PLANNING DIVISION INITIAL STUDY r less. Due to the low number of residences in the area (approximately 16), visual impacts will only be 2 0 temporary and are considered to be less than significant. Upon completion, all project improvements a` will mainly be below ground so there will be no long-term visual impacts,and no mitigation is required. _ L I.d No Impact.Development of the proposed flood control improvements would not require the installation of any permanent outdoor lighting, although some temporary lighting of construction areas may be o necessary for the maintenance of public safety and security. Therefore,there will be no significant long- term impacts related to light and glare and no mitigation is required. 0 O II.

Farmland maps are compiled by the California Department of Conservation, Farmland w Mapping and Monitoring Program (FMMP), pursuant to the provisions of Section 65570 of the .. California Government Code. These maps utilize data from the United States Department of Conservation(USDA.)Natural Resource Conservation Service(NRCS) soil survey and current land use s information using eight mapping categories and represent an inventory of agricultural resources within 0 San Bernardino County. The maps depict currently urbanized lands and a qualitative sequence of Q agricultural designations. Maps and statistics use a process that integrates aerial photo interpretation, Twin Creek Orange Show Road Storm Drain Project 15 Packet Pg.242 5:J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r field mapping,a computerized mapping system,and public review. 0 L a The project area is designated as "Urban & Built-Up" land, by the FMMPt and no Prime, Unique, or e Statewide Important Farmlands are located on site. In addition, all project work will occur with public road rights-of-way and a public flood control channel.As no conversion of such farmland would occur, no impact related to this issue would occur with implementation of the proposed project. E 0 w II.b No Impact. The California Land Conservation Act of 1965, commonly referred to as the Williamson -0 Act, enables local government to enter into contracts with private landowners for the purpose of o restricting specific parcels of land to agriculture or related open space use. In return, landowners receive property tax assessments much lower than normal because they are based upon farming and open space o uses as opposed to full market value. The purpose of the Williamson Act is to encourage property owners to continue to farm their land and to prevent the premature conversion of farmland to urban an uses. The project alignment is not located within a Williamson Act contract area;2 therefore, no impact m would result from the proposed development and no mitigation is required. 0 ILe No Impact. The project alignment is currently developed with flood control and roadway m improvements. There are no agricultural or forestry-related uses and it does not have any designated V forest land uses. The proposed project would not conflict with existing forest zoning, cause rezoning of forest land, or result in the loss or conversion of forest lands to non-forest uses as no such resources existing within the City. Therefore, no impacts associated with these issues would occur and no 0 mitigation is required. w� as 0 II.d No Impact.Please refer to Checklist Response II.c. 0) m Z II.e No Impact. Implementation of the proposed project would not result in the conversion of agricultural a land to a non-agricultural use as no agricultural uses exist on site.

Y a Discussion m III.a No Impact. The project is located within the South Coast Air Basin (Basin) and is within the jurisdiction of the South Coast Air Quality Management District(SCAQMD). The Basin is bounded by Q the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. It includes all of Orange County, the non-Antelope Valley portions of Los Angeles x County,and the non-desert portions of Riverside and San Bernardino Counties.The project is located in w the City of San Bernardino. E 0 t ca Q Twin Creek Orange Show Road Storm Drain Project 17 Packet Pg. 244, 5.J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r The current regional air quality plan is the 2012 Air Quality Management Plan(AQMP)adopted by the d SCAQMD in February 2013 . The AQMP proposes attainment demonstration of the federal PM2,5 CL standards through a more focused control of sulfur oxides SO directly emitted PM , and nitrogen a g ( x)� Y z s� g = oxides(NOx)supplemented with volatile organic compounds(VOC)by 2015.The 8-hour ozone control strategy builds upon the PMz,5 strategy, augmented with additional. NOx and VOC reductions, to meet o the standard by 2024 assuming a"bump-up"is obtained. A bump-up is a voluntary reclassification of a E L non-attainment area to a higher classification, allowing for an extension of an attainment deadline. The t W° Basin is currently a federal and state nonattainment area for PM,o,PM2,s,and ozone. 0 The proposed project entails the construction of approximately one mile of below grade flood control improvements (pipelines, reinforced concrete box channels, etc.) all of which will be built within 0 existing flood control or roadway rights-of-way. The road portion of the project area contains no zoning designations,while the Twin Creek channel is designated Public Flood Control.Therefore,the proposed 0 project is consistent with existing General Plan and zoning designations. co L The AQMP incorporates local General Plan land use assumptions and regional growth projections developed by the Southern California Association of Governments (SCAG) to estimate stationary and d mobile source emissions associated with projected population and planned land uses. If a new land use is consistent with the local General Plan and the regional growth projections adopted in the AQMP,then = the added emissions generated by the new project have been evaluated, are contained in AQMP, and would not conflict with or obstruct implementation of the regional AQMP. Since the project does not o conflict with General Plan or zoning designations, it is not expected to hinder or obstruct implementation of the AQMP. o Another measurement tool in determining consistency with the AQMP is to determine how a project Z accommodates the expected increase in population or employment. In this case, the proposed project Q would not result in any direct population or housing increase, and is only intended to accommodate 0 projected runoff volumes in this portion of the City. Based on this information, the proposed project Q would not impair implementation of the AQMP(i.e.,no impact and no mitigation required). ,°� d Finally,the proposed project would accommodate growth that has been projected for the project vicinity and sub-region through the construction of needed infrastructure, thus removing an impediment to growth within the project area. Emissions projections used to establish SCAQMD attainment objectives reflect adopted regional and local land use plans. Therefore,the emissions associated with the proposed >, project are within the amounts already accounted for in the AQMP, and no significant inconsistency with the AQMP would occur in this regard, and no mitigation is required. U) 16 III.b. Less than Significant Impact with Mitigation'. The SCAQMD has developed the CEQA Air Quality Handbook that establishes suggested significance thresholds based on the volume of pollution emitted. -0 According to the Handbook, airy project in the Basin with daily emissions that exceed any of the following c thresholds should be considered as having an individually and cumulatively significant air quality impact: P in • 55 lbs.per day of ROC(reactive organic compounds)(75 lbs./day during construction); `t Z • 55 lbs.per day of NOx(oxides of nitrogen)(100 lbs./day during construction); � .c • 550 lbs.per day of CO(carbon monoxide)(550 lbs./day during construction); w • 150 lbs.per day of PM,()(150 lbs./day during construction);and E z Final 2012 Air Quality Management Plan,South Coast Air Quality Management District,final adopted February 2013. Construction emissions only,other impacts are less than significant. Q Twin Creek Orange Show Road Storm Drain Project 18 Packet Pg. 245 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY Y V • 150 lbs.per day of SOX(oxides of sulfur)(150 lbs./day during construction). °' 0 L a- Construction Emissions. Air quality impacts would occur during site preparation, including roadway ,_ demolition, asphalt removal, grading, and construction equipment exhaust. Major sources of emissions include exhaust emissions from construction vehicles and equipment and fugitive dust generated by construction vehicles and equipment traveling over exposed surfaces, as well as by soil disturbances o from grading and filling. Grading and construction activities would cause combustion emissions from Cn utility engines,heavy-duty construction vehicles,haul trucks,and vehicles transporting the construction -0 crew. Exhaust emissions during grading and construction activities envisioned on site would vary as 0 construction activity levels change. Fugitive dust emissions are generally associated with demolition, 3 land clearing, exposure of soils and cut and fill operations. Dust generated daily during construction o would vary substantially, depending on the level of activity, the specific operations, and weather N conditions. The emissions associated with site grading and the construction are estimated in Table C. These estimates are based on the reasonable worst case assumptions for daily construction activities outlined in the project description(section 8,page 4). p e to Table C—Short-Term Construction Emissions(Worst Case Daily) U Total Regional Pollutant Emissions,lbs/day = Construction Fugitive Exhaust Fugitive Exhaust Activity ROG NOx CO SO' PMto PMta PM',5 PM's CO'e 0 Demolition 4.6 46.0 32.0 0.04 0.25 2.7 0.062 2.5 4,100 "- I'renching 6.0 66.0 38.0 0.064 0.52 3.3 0.14 3.0 6,700 m L) Construction 5.8 46.0 32.0 0.053 1 0.50 2.7 0.14 2.6 5,300 d Peak Daily Z Emissions 6.0 66.0 38.0 0.064 3.8 3.1 6,700 Q 0 SCAQMD 75 1.00 550 150 150 55 Q Thresholds No Threshold to Significant to Emissions?

During the construction phases of development, on-site stationary sources, heavy- duty construction vehicles, construction worker vehicles, and energy use would generate emissions. Exhaust emissions during the construction activities envisioned on site would vary daily as construction activity levels change. The volume of construction equipment exhaust would not exceed SCAQMD a+ daily thresholds. Q Fugitive Dust.Fugitive dust emissions are generally associated with demolition,land clearing, exposure B of soils, and cut and fill operations. Dust generated daily during construction would vary substantially, x depending on the level of activity, the specific operations, and weather conditions. Even during peak w grading days, daily total construction emissions would not exceed the SCAQMD threshold for PM10, and all other emissions are below SQACMD daily thresholds as well. With the implementation of the m standard conditions such as frequent watering (i.e., minimum twice a day) fugitive dust emissions can be reduced by approximately 50 percent. Even when combined with the nearly 5 pounds per day of ttu PM10 generated by equipment exhaust,the total mitigated daily dust emission would be well below the a Twin Creek Orange Show Road Storm Drain Project 19 Packet Pg.246-' 5.J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r SCAQMD threshold of 150 pounds per day, as shown in Table C. When properly coordinated, °' 0 construction equipment emissions would not exceed the daily thresholds for the criteria pollutants of o NOx,ROC,CO,SOx,or PM1o. c L Local Significance Thresholds. In addition to emission generation, the SCAQMD CEQA Handbook requires an evaluation of how construction emissions may affect "sensitive receptors" like residents, o young children, the elderly, etc, during construction using local significance thresholds (LSTs). As y indicated in Table D, the project LSTs would be considerably lower than the SCAQMD standards for a NOx, CO, and PM,o, and were just below the SCAQMD threshold for PMZ,$. These estimates take into 0 account the proximity of construction equipment to the existing residences near the southeast corner of the project alignment. Therefore,the project will not result in a significant air quality impact relative to 0 LSTs(LSA Associates,Inc.,January 2015,Appendix A). U) d Mitigation Measures. In order to fully mitigate for construction-related air quality impacts,the City will require the preparation and approval of a Dust Control Plan to be reviewed and approved by the Public 0 Works Division. In addition, the project proponent shall incorporate the following mitigation measures X into the project. Adherence to these measures would reduce total daily construction emissions of PMIo P to below the SCAQMD threshold. The other four air pollutant emissions would be below the daily V thresholds established by the SCAQMD without mitigation. 3 AIR 1 The project shall comply with the requirements of SCAQMD Rules 402 and 403,Fugitive Dust, 0 which require the implementation of Reasonable Available Control Measures (RACM) for all fugitive dust sources, and the AQMP, which identifies Best Available Control Measures p (BALM) and Best Available Control Technologies(BACT)for area sources and point sources, respectively.This would include but would not be limited to the following actions; z 1. The project proponent shall ensure that construction equipment is properly maintained and o serviced to minimize exhaust emissions. ,Q 2. The project proponent shall ensure that existing power sources are utilized where feasible U) via temporary power lines to avoid on-site power generation. 3. The project proponent shall ensure that construction employees be informed of ride-sharing c and transit opportunities. M 4. The project proponent shall ensure that any portion of the site to be graded shall be a prewatered to a depth of three feet prior to the onset of grading activities. Cn 5. The project proponent shall ensure that twice daily watering of the site or other soil stabilization methods shall be employed on an ongoing basis after the initiation of any on- site grading activity. Portions of the site that are actively being graded shall be watered regularly to ensure that a crust is formed on the ground surface, and shall be watered at the end of each workday. 6. The project proponent shall ensure that all disturbed areas are treated to prevent erosion until the site is constructed. Q r 7. To reduce the potential for wind erosion,the project proponent shall ensure that landscaped areas,if any,are installed as soon as possible. X w 8. The project proponent shall ensure that SCAQMD Rule 403 is adhered to, ensuring the _ cleanup of construction-related dirt on approach routes to the project alignment. E E 9. The project proponent shall ensure that all grading activities are suspended during first and 0 second stage ozone episodes or when wind speeds exceed 25 miles per hour. a p Twin Creek Orange Show Road Storm Drain Project 20 Packet Pg.247< CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY 10.

Limit all on-site traffic speeds to 15 mph or less. p E Operational Emissions. Since the project will not introduce any developed land uses into the project o alignment, there will be only minor long-term pollutant emissions associated with vehicular use or stationary sources mainly during maintenance activities created by the consumption of fossil fuels. There would also be no emissions from the consumption of natural gas on site or electricity (runoff ° controlled by gravity). 3 O Local Significance Thresholds. In addition to emission generation, the SCAQMD CEQA Handbook requires an evaluation of how regional emissions may affect"sensitive receptors" like residents, young C children, the elderly, etc. over the long term, using Local Significance Thresholds (LSTs). The air T quality assessment for the project indicates that the project LSTs would be considerably lower than the O SCAQMD standards for NOx, CO,PM,o, and PMz,5."These estimates take into account the proximity of construction equipment to the existing residences near the southeast corner of the project alignment. V Therefore,the project will not result in a significant air quality impact relative to LST(refer to Table D ° below). Impacts are less than significant and no mitigation is required.

The SCAQMD CEQA Handbook recommends an assessment of the buildup of carbon N monoxide(CO)from vehicles idling at congested intersections to determine if the traffic generated by a proposed project would exceed any state or federal CO standards. In this case, the project does not ;_° introduce any new land uses and so it will not generate long-term traffic other than occasional E maintenance trips. Therefore, project-related traffic would not create any CO hotspots by increased traffic congestion,impacts are less than significant,and no mitigation is required. as in IIl.c Less than Significant. As stated in the response to Checklist Question III.a, the project is in a non- a attainment basin for PM1o, PMz,5, and ozone. The proposed project would incrementally contribute non- attainment pollutants to the air basin. However, project emissions would be below SCAQMD Z significance thresholds, as discussed in question III.b. The AQMP incorporates local General Plan land w use assumptions and regional growth projections developed by the SCAG to estimate stationary and mobile source emissions associated with projected population and planned land uses. The proposed project would be consistent with the development envisioned in the City's General Plan (i.e., General z Plan and zoning designations), therefore, the cumulative effects associated with development of the proposed uses has already been addressed in the AQMP, there are no significant impacts and no Q mitigation is required. Twin Creek Orange Show Road Storm Drain Project 21 Packet Pg.248! CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r a� III.d Less than Significant Impact with Mitigation. Sensitive receptors are defined as populations that are more susceptible to the effects of pollution than the population at large. The SCAQMD identifies the c following as sensitive receptors: long-term healthcare facilities, rehabilitation centers, convalescent centers, retirement homes, schools, playgrounds, childcare centers, and athletic facilities. The project alignment is in an area that is largely vacant but with scattered industrial and commercial uses. E Although there are no institutional sensitive receptors in the project area, there are approximately ° Cn sixteen homes immediately adjacent to the project construction area (along Orange Show Road and Lena Road). The closest off-site sensitive land uses to the project alignment are two residences located o approximately 50 feet from planned construction along Orange Show Road. The construction of the project alignment would temporarily produce construction emissions near these residences, but o emissions would be short-term and would not exceed SCAQMD thresholds as indicated in previously referenced Table B. As indicated in Section III.b, the project would not exceed the Local Significance as Thresholds for construction or operational emissions for residences closest to the project alignment c (LSA Associates, Inc., January 2015, Appendix A). Operational emissions from the project would also M be below the SCAQMD thresholds. Therefore, impacts related to sensitive receptors issue are considered to be less than significant with implementation of Mitigation Measure AIR-1, and no additional mitigation is required. t c Due to its nature,the proposed project does not require a Health Risk Assessment(HRA)to determine if project emissions from trucks such as diesel particulates would cause any long-term health risks for o residents living closest to the project alignment. Therefore, potential health impacts are less than significant and no mitigation is required. 0 IILe Less than Significant Impact. During construction, diesel-powered vehicles and equipment in use on z the site could create minor impacts regarding odors. These odors are temporary and not likely to be a noticeable beyond the project boundaries. SCAQMD Rules 1108 identifies standards regarding the application of asphalt, and adherence to the standards identified in this rule would reduce temporary Q odor impacts to a less than significant level. Long-term objectionable odors are not expected to occur because the project involves flood control improvements that will largely be undergrounded, so impacts o: would be less than significant and no mitigation is required. 0 co III.f Less than Significant Impact with Mitigation. LSA estimated greenhouse gas (GHG) emissions which are included in Appendix A of this document(see also previous Table B). The project GHG study provides information on their physical and chemical attributes, their regulatory framework, and r evaluates potential GHG emissions associated with the proposed project. Modeled project emissions in N the study were based on project design, anticipated vehicle usage, and energy usage for the project. In addition, the evaluation was prepared in conformance with appropriate standards, utilizing procedures r- and methodologies in the SCAQMD CEQA Air Quality Handbook and the State CEQA Guidelines. c The GHG study estimated that the project would produce a maximum of 6,700 pounds per day of GHGs in during construction (worst case daily estimate — see Table C). Assuming all of the work could be completed in four months if it were done at one time, the project would emit a total of 294.8 tons of Q GHGs during construction(6,700 pounds per day times 88 days). The SCAQMD has not yet established a formal GHG emission significance threshold, therefore, the project is not expected to result in any X significant long-term GHG emissions since the project does not involve new land uses and its function w depends on gravity flow so it will have no energy use from pumping or equipment operation, c d E R Q Twin Creek Orange Show Road Storm Drain Project 22 Packet Pg.249' CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY The following measure is recommended to help minimize GHG emissions from the project during d 0 construction to the extent practical: 0- c GCC-1 To the extent practical and to the satisfaction of the City, the following shall be incorporated into the design and construction of the project: E • Use locally produced and/or manufactured building materials for at least 10 percent of the o construction materials used for the project. in Use "Green Building Materials," such as those materials that are resource efficient, and 0 • M recycled and manufactured in an environmentally friendly way, for at least 10 percent of the 3 project. 0 • Limit unnecessary idling of construction equipment. A reduction in equipment idling would N m reduce fuel consumption,and therefore,GHG emissions. _ R • Maximize the use of electricity from the power grid by replacing diesel- or gasoline- 0 powered equipment during construction. This would reduce GHG emissions because _y. melectricity can be produced more efficiently at centralized power plants. U After implementation of application of regulatory requirements and the recommended mitigation measure, the project would implement appropriate GHG reduction strategies and would not conflict with or impede implementation of reduction goals identified in AB 32,the Governor's Executive Order o S-3-05, and other strategies to help reduce GHGs to the level proposed by the Governor. The control measures listed in Mitigation Measure GCC-I would further reduce the project's GHGs, and p therefore,the project's contribution to GHG emissions. Z The project would not be significantly affected by global climate change since it is away and elevated o from the coast (predicted sea level rise) and it is not in a urban/wildland interface (increased drought Q and fire risks). 0 Ill.g Less than Significant Impact.The Climate Action Team(CAT)and the CARB have developed several reports to achieve the Governor's GHG targets that rely on voluntary actions of California businesses, local government and community groups, and state incentive and regulatory programs. These include the CAT's 2006 "Report to Governor Schwarzenegger and the Legislature," the CARB's 2007 "Expanded List of Early Action Measures to Reduce Greenhouse Gas Emissions in California," and the .a CARB's "Climate Change Proposed Scoping Plan: a Framework for Change." The reports identify strategies to reduce California's emissions to the levels proposed in Executive Order S-3-05 and AB 32 in (i.e., 29% below existing"business as usual" emissions) as shown in Tables E and F below. However, the proposed project does not involve development of any new land uses or architectural facilities,only = underground storm drainage improvements, so there will only be short-term GHG emissions from construction and no long-term GHG emissions from the project. Therefore, the project does not need to comply with the long-term recommended CAT or CARE actions. In addition, implementation of in Mitigation Measure GCC-I will help reduce construction-related GHG emissions. With implementation Q of the recommended mitigation measure, the proposed project will have less than significant impacts related to greenhouse gases and global climate change. s X w C m E ca Q Twin Creek Orange Show Road Storm Drain Project 23 Packet Pg.250 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY Table E—Recommended Actions for Climate Change Project Summary 0 L ID Applicable to Will Project Conflict a c No. Sector Strategy Name Project? with Implementation? � T-1 Transportation Pavley I and II—Light-Duty Vehicle GHG Standards No No E 0 T-2 Transportation Low Carbon Fuel Standard(Discrete Early No No Action) Cn T-3 Transportation Regional Transportation-Related GHG No No 0 Targets T-4 Transportation Vehicle Efficiency Measures No No U) T-5 Transportation Ship Electrification at Ports(Discrete Early No No m Action) 0) R T-6 Transportation Goods-movement Efficiency Measures No No 0 T-7 Transportation Heavy Duty Vehicle Greenhouse Gas Y Emission Reduction Measure— d Aerodynamic Efficiency(Discrete Early No No U Action) T-8 Transportation Medium and Heavy-Duty Vehicle r Hybridization No No 0 T-9 "Transportation High Speed Rail No No E-I Electricity and Increased Utility Energy Efficiency Natural Gas Programs.More Stringent Building and No No Appliance Standards Z rz E-2 Electricity and Increased Combined Heat and Power Use by 0 Natural Gas 30,000 GWh No No Q 0 E-3 Electricity and Renewable Portfolio Standard rn Natural Gas No No � E-4 Electricity and Million Solar Roofs ce) c Natural Gas No No 00 CR-1 Electricity and Energy Efficiency Natural Gas No No CR-2 Electricity and Solar Water Heating N Natural Gas No No GB-I Green Buildings Green Buildings No No _ W-1 Water Water Use Efficiency Nn tr d c W-2 Water Water Recycling No No W-3 Water Water System Energy Efficiency No No in Q W-4 Water Reuse Urban Runoff No No .Q W-5 Water Increase Renewable Energy Production No No t x W-6 Water Public Goods Charge(Water) No No W I-1 Industry Energy Efficiency and Cost-Benefits Audits = Q for Large Industrial Sources No No E I-2 Industry Oil and Gas 13xtraction GHG Emission 0 Reduction No No w Q Twin Creek Orange Show Road Storm Drain Project 24 PacYCet 4Pg.251 CITY OF SAN BERNARDINO Opp" PLANNING DIVISION INITIAL STUDY Y Table E—Recommended Actions for Climate Change Project Summary o ID Applicable to Will Project Conflict CL No. Sector Strategy Name Project? with Implementation?

Additionally, implementation of the project will not result in co degradation of critical habitat that occurs downstream. The Twin Creek Channel will continue to function as a flood control channel,and the hydrologic regime of downstream areas will not be affected. a a The CDFW, USFWS, local agencies, and special interest groups, such as the CLAPS, maintain lists of Cn species that they consider to be in need of monitoring. Legal protection for these special interest species r varies widely.Of the special interest species known to occur in the general area,only the burrowing owl = (Athene cunicularia)could potentially be found on site.No other special interest species are expected to m occur within the project alignment due to unsuitable habitat conditions existing on the site (i.e., the a) small portion of the Twin Creek Channel and the one mile of improved public roadways).

Surveys and Q relocation, if applicable, shall be conducted between September I and January 31.

The CDFW Staff Report on Burrowing Mitigation includes appropriate E buffer zones based on the timing of construction that will be implemented, if needed. If ° occupied burrows are too close to proposed construction areas to allow for appropriate protection in place,a qualified biologist will discuss additional avoidance options with CDFW.

Q 0 IV.d Less than Significant Impact with Mitigation. Due to the area's predominantly developed nature and W the site's current condition, the roadway portion of the project alignment does not provide suitable foraging ground or localized movement for wildlife, however, the Twin Creek portion of the site does co provide limited value to biological resources in this regard. Habitat fragmentation occurs when a proposed action results in a single, unified habitat area being divided into two or more areas, such that �+ the division isolates the two new areas from each other.Isolation of habitat occurs when wildlife cannot move freely from one portion of the habitat to another or from one habitat type to another. An example U) is the fragmentation of habitats within and around clustered residential development. Habitat 20 fragmentation may occur when a portion of one or more habitats is converted into another habitat, as c when scrub habitats are converted into annual grassland habitat because of frequent burning. The San a Bernardino Valley is subject to ongoing urbanization and consequent loss of habitat and open space. Furthermore, the project alignment consists of a flood control channel and two fully developed roadways with nearby urban development, so it is not part of a larger interconnected movement corridor Q for wildlife. Therefore, impacts are less than significant. However, implementation of Mitigation Measure 13I0-2 will help assure no net loss of riparian resources within the watershed as a result of .a r project implementation. w It is possible that nearby nesting habitat may be indirectly affected by proposed project activities. Trees and shrubs on nearby residential properties may provide nesting habitat for birds at various times of the E year. Increased noise and human presence during construction activities may cause birds to abandon nests or negatively affect nestlings.Typically,the CDFW requires construction activities within 300 feet t0 of trees and shrubs be scheduled outside of the avian nesting season.

Implementation of the proposed project would require on-site excavation which is expected to be balanced on site (i.e., removed soil will be stockpiled then replaced and compacted once the new flood control improvements are installed). Although not expected, there may have to be a minor amount of imported fill for overexcavation or replacement of >+ any unconsolidated fill if any is discovered during grading. The import or export of earth would be subject to haul permits issued by the City.

Fault rupture is the most easily avoided seismic hazard. The Alquist-Priolo Earthquake o Fault Zoning Act(A-P Act)mitigates fault rupture hazards by prohibiting the location of structures for human occupancy across the trace of an active fault. The A-P Act requires the State Geologist to a delineate "Earthquake Fault Zones" along faults that are "sufficiently active" and "well defined." The o boundary of an"Earthquake Fault Zone" is generally 500 feet from major active faults and from 200 to 300 feet from well-defined minor faults. The mapping of active faults has been completed by the State o Geologist. These maps are distributed to all affected cities, counties, and State agencies for their use in N developing planning policies and controlling renovation or new construction, a� As identified in the City's General Plan,the project alignment is not located within the boundaries of an c° earthquake fault zone for fault-rupture hazard as defined by the Alquist-Priolo Earthquake Fault Zoning Act.' Although no active traces of fault have been identified within the project limits,the City is situated d in a seismically active area. Ground shaking is expected to be the primary hazard likely to affect the v project. The project does not propose to construct any occupied structures on or near fault structures, so there is no impact and no mitigation is required. L 0 VIA Less than Significant Impact with Mitigation. Erosion of soil could occur through being located in a � high wind area or through construction activities exposing areas to precipitation and water erosion. 0 Based on the City's General Plan, the project alignment is not identified as being located in an area a, susceptible to high winds.2 Development would require the movement of on-site soils, although no Z substantial import of fill material is expected. Prior to the issuance of improvement plans or a grading a permit, the project proponent would be required to prepare and submit a detailed grading plan for the �0 project improvements in conformance with applicable standards of the City's Grading Ordinance. a 0 Development of the site would involve more than one acre;therefore,the proposed project is required to obtain a National Pollutant Discharge Elimination System (NPDES) permit. A Storm Water Pollution Prevention Plan (SWPPP) would also be required to address erosion and discharge impacts associated with the proposed on-site grading. In addition to preparation of an SWPPP, new development projects submitted to the City are required to submit a project-specific Water Quality Management Plan (WQMP). The WQMP identifies specific measures to treat and/or limit the entry of contaminants into 0 the storm drain system. The WQMP is required to be incorporated by reference or attached to the N project's SWPPP as the Post-Construction Management Plan. Soils covering the majority of the project alignment have a slight to moderate erosion hazard potential, but any imported fill material would have c to be approved by the City based on recommendations from a qualified soils engineering firm. The o project would be required to adhere to the City's Grading Ordinance, obtain an NPDES Permit, and c prepare an SWPPP for construction and operational impacts associated with soil erosion hazards. The °S Cn project area will be under sequential construction for an extended period of time,and there may be times when no construction is occurring, so the SWPPP and WQMP will need to address this extended Q construction period. With implementation of these standard City development requirements, plus Q Mitigation Measures HYD-1 and HYD-2 in the hydrology section, potential erosion impacts will be x reduced to less than significant levels and no additional mitigation is necessary. w w c m E ca Figure S-3 Alquist-Priolo Study Zones,City of San Bernardino General Plan,November 2005.

Liquefaction is a phenomenon that occurs when strong earthquake shaking causes soils to collapse from a sudden loss of cohesion and undergo a o transformation from a solid to a liquefied state. Factors influencing a site's potential for liquefaction include area seismicity, the type and characteristics of on-site soils, and the level of groundwater. a� Liquefaction typically occurs in areas where groundwater is shallower than approximately 50 feet, and C where there is the presence of loose, sandy soils.

Construction of the proposed development will require r_ excavation which may allow eroded soils and other pollutants to enter the storm drain system. Pollutants tP such as sediment, nutrients, heavy metals, toxic organics, trash and debris, and contaminants may be conveyed by storm runoff of impermeable surfaces (e.g., streets). The City implements National Pollutant Discharge Elimination System (NPDES) requirements for surface water discharge for all V qualifying activities,including the proposed project.The site is already fully developed with impervious S surfaces, and the project alignment will return to that condition after project construction. However' 1 3 — development of the project alignment is in excess of one acre;therefore,the project is required to obtain o coverage under an NPDES permit,which includes the submittal of a Notice of Intent(NOI) application to the State Water Resources Control Board (SWRCB),the receipt of a Waste Discharge Identification as 0 Number(WDIN) from SWRCB, and the preparation of an SWPPP for construction discharges. During the construction period, the project would use a series of Best Management Practices (BMPs)to reduce z erosion and sedimentation. These measures may include the use of gravel bags, silt fences, hay bales, 0- check dams, hydroseed, and soil binders. The construction contractor would be required to operate and 0 maintain these controls throughout the duration of on-site activities. In addition, the construction Q contractor would be required to maintain an inspection log and have the log on site to be reviewed by ,°n the City and representatives of the RWQCB. c� The implementation of NPDES permits ensures that the state's mandatory standards for the maintenance co of clean water and the federal minimums are met. Coverage with the permit would prevent sedimentation and soil erosion through implementation of an SWPPP and periodic inspections by >, RWQCB staff. An SWPPP is a written document that describes the construction operator's activities to comply with the requirements in the NPDES permit. The SWPPP is intended to facilitate a process N whereby the operator evaluates potential pollutant sources at the site and selects and implements BMPs 6 designed to prevent or control the discharge of pollutants in stormwater runoff. Construction of the project alignment would require the demolition of the existing on-site structures and c disturbance of underlying soils.During the construction period,grading and excavation activities would 9 result in exposure of soil to storm runoff, potentially causing erosion and sediment in runoff. If not managed through BMPs, the runoff could cause erosion and increased sedimentation in local drainage ways. By volume, sediment is the principal component in most storm runoff. Sediments also transport :c substances such as nutrients, hydrocarbons, and trace metals, which are conveyed to the receiving x waters. The potential for chemical releases is present at most construction sites in the form of fuels, w solvents, glues, paints, and other building construction materials. Once released, substances such as c fuels, oils,paints, and solvents could be transported to nearby surface waterways and/or to groundwater E in stormwater runoff, wash water, and dust control water, potentially reducing the quality of the receiving waters and potentially result in impairment of downstream water sources. Q Twin Creek Orange Show Road Storm Drain Project 42 Packet Pg. 269 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r The NPDES permit program was established under Section 402 of the Clean Water Act,which prohibits � 0 the unauthorized discharge of pollutants, including municipal, commercial, and industrial wastewater a discharges.

However, adherence to the BMPs identified by the above mitigation measures would o reduce impacts associated with short-term stormwater discharges during project construction.Therefore, 0, impacts associated with this issue are reduced to a less than significant level. z r CL The proposed project would not change the permanent drainage pattern of the project area, and will not .a increase the overall amount of impermeable surfaces and thus would not alter the current drainage Q pattern. During construction, storm runoff from the roadways may carry a variety of pollutants u°, including, but not limited to, trash, debris, oil and grease, organic compounds (specifically solvents), metals,sediment/turbidity,nutrients,oxygen-demanding substances,and pesticides. 0 0 The implementation of the following pollution prevention and source control measures would reduce potential water quality impacts during construction to less than significant levels: 0 HYD-1 Prior to the issuance of a grading permit,the project applicant shall file and obtain a Notice of Intent (NOI) with the Regional Water Quality Control Board in order to be in compliance with the State NPDES General Construction Storm Water Permit for discharge of surface runoff associated with construction activities. Evidence that this has been obtained (i.e., a copy of the -� Waste Discharger's Identification Number) shall be submitted to the City for coverage under c the NPDES General Construction Permit. The NOl shall address the potential for an extended in and discontinuous construction period based on funding availability. Q HYD-2 Prior to the issuance of a grading, the project applicant shall submit to and receive approval from the City of San Bernardino a Storm Water Pollution Prevention Plan (SWPPP). The s SWPPP shall include a surface water control plan and erosion control plan citing specific x W measures to control on-site and off-site erosion during the entire grading and construction Y period. In addition,the SWPPP shall emphasize structural and nonstructural Best Management (D Practices(BMPs)to control sediment and non-visible discharges from the site. The SWPPP will L include inspection forms for routine monitoring of the site during construction phase to ensure NPDES compliance and additional BMPs and erosion control measures will be documented in a Twin Creek Orange Show Road Storm Drain Project 43 Packet Pg.210 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY i+ V the SWPPP and utilized if necessary. The SWPPP shall address the potential for an extended Y P and discontinuous construction period based on funding availability. The SWPPP will be kept 0 a on site for the entire duration of project construction and will be available to the local RWQCB c for inspection at any time. Some the BMPs to be implemented may include the following: 0 • Sediment discharges from the site may be controlled by the following: sandbags, silt fences, E straw wattles and temporary basins (if deemed necessary), and other discharge control o devices. The construction and condition of the BMPs will be periodically inspected during to construction and repairs will be made when necessary as required by the SWPPP. M 0 • Materials that have the potential to contribute to non-visible pollutants to stormwater must not be placed in drainage ways and must be contained, elevated, and placed in temporary 0 storage containment areas. N d • All loose piles of soil, silt, clay, sand, debris, and other earthen material shall be protected in a reasonable manner to eliminate any discharge from the site. Stockpiles will be L surrounded by silt fences and covered with plastic tarps. 0 • In addition, the construction contractor shall be responsible for performing and documenting the application of BMPs identified in the SWPPP.Weekly inspections shall be U performed on sandbag barriers and other sediment control measures called for in the 0 SWPPP. Monthly reports and inspection logs shall be maintained by the Contractor and N reviewed by the City of San Bernardino and the representatives of the State Water p Resources Control Board. In the event that it is not feasible to implement specific BMPs, the City of San Bernardino can make a determination that other BMPs will provide p equivalent or superior treatment either on or off site. According to the Regional Water Quality Control Board's website',neither Twin Creek nor this portion Z of the Santa Ana River are considered 303(b)"Impacted Water Bodies". The closest 303(b)body is the 0 portion of the Santa Ana River approximately a mile downstream of the confluence of Twin Creek, < 4 south of the I-10 Freeway. Therefore, potential runoff from the project alignment would not directly 0 discharge into any impaired water bodies. Adherence to Mitigation Measures HYDA and fIYD-2 and tY measures included in the SWPPP and NPDES permit would reduce potential water quality impacts to less than significant levels,and no additional mitigation is required. c 00 M VIII.b No Impact. The project does not propose any new land uses and will result in the same amount of impervious surfaces compared to existing conditions in the road portion of the project. Construction of the channel portion of the project(i.e., within the Twin Creek channel)will result in a small increase in in impervious surface along the east bank of the channel to provide additional protection from erosion 6 around the outlet structure (Previous Section 8 of the Project Description -page 2 - states maximum disturbance will be 0.28 acre). Therefore,the project will have minimal impacts,regarding groundwater a supplies or quality, and no mitigation rs required. m c rn VIII.c-d Less than Significant Impact. The City of San Bernardino Public Works Division administers storm to drain and flood control facilities within the City. The storm drain system has been divided into sub-areas Q within the City based upon the San Bernardino County Flood Control District's Comprehensive Storm Drain Plans. The project is located within Storm Drain. Sub-Area 2, which corresponds to a portion of c Comprehensive Storm Drain Plan No. 7,which covers the northwesterly portion of the City. w c m E h(112;//svww,watertx>ardti.ca.aov/water issu&pro am" trndl/mt rwrated2OiOshtmltwbid=CAR8012700019990211142130 Q a Twin Creek Orange Show Road Storm Drain Project 44 Pack�£�Pg.271' CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r The proposed project is to replace existing undersized hood control improvements within Orange Show o Road and Lena Road, and the drainage outlet into Twin Creek at Orange Show Road. `Phis is a public benefit project that will improve flood control conditions. Approval of drainage features/improvements are made through the plan check process. As part of this process, all drainage improvements would be required to meet the City's development standards. Erosion, sedimentation, and siltation impacts are adequately addressed through adherence to Mitigation Measures HYD-I and HYD-2. Because the o project would improve flood protection for upstream land uses, impacts related to this issue are Cn anticipated to be less than significant with implementation of the recommended mitigation. 0 VIILe Less than Significant Impact. The presence of impermeable surfaces such as streets generally increases the velocity and volume of surface runoff compared to native soils. As urban runoff flows 3 0 over streets,it carries off pollutants such as automobile oil and antifreeze,pesticides, animal waste, and N litter into the storm drain system. The storm drain system collects water from the streets and transports it directly or indirectly to local water supplies and eventually the Pacific Ocean. Urban runoff from the storm drains is typically not filtered or treated. p Federal environmental regulations based on the CWA require the control of pollutants from Municipal aa) Separate Storm Sewer Systems (MS4s), construction sites and industrial activities. MS4s include U drainage systems owned and maintained by the City of San Bernardino. Discharges from such sources S were brought within the NPDES permit process by the 1987 Clean Water Act amendments and the 3 h subsequent 1990 promulgation of stormwater regulations by the U.S. Environmental Protection Agency. o Because the project proponent would be required to adhere to storm drainage requirements identified 0 within the NPDES permit process as well as provisions required by the City of San Bernardino, a less o than significant impact related to this issue is anticipated to occur with the implementation of the 0 proposed flood control project,and no mitigation is required. Z CL VIII.f Less than Significant with Mitigation. Please refer to the Response to Checklist Response VIlla. In °a accordance with the construction NPDES permits and as monitored by the City, the project developer Q would be required to implement BMPs during the construction of the proposed flood improvements. 0) Adherence to the mitigation measures HYD-1 and HYD-2, along with City-mandated water quality W requirements, will reduce the water-quality impact associated with this issue to a less than significant level,and no additional mitigation is required. M VIII.g Less Than Significant Impact. The road portion of the proposed project is not located within an area identified as being subject to flood hazards, either by the City of San Bernardino (Figure S-1 of the General Plan)or the Federal Emergency Management Agency,l the proposed project would not impede N or redirect flood flows (i.e., FEMA data shows the Twin Creek Channel is Zone AE with "base flood elevations determined" and Orange Show Road and Lena Road are Zone A with "no base flood E elevations determined"). The channel-related improvements within Twin Creek are likely within a 100- year flood zone, however, these are designed to prevent erosion of the surrounding bank and not to impede flow within the channel. No impact related to this issue is anticipated to occur with the implementation of the proposed project,and no mitigation is required. Q VIII.h Less than Significant Impact. Flood control in the City provides an integrated approach for regional .a and local drainage flows. This system includes debris basins, storm channels, and levees. The road w portion of the project is not located within a I00-year flood hazard area, but the channel portion of the .. project (i.e., improvements within the Twin Creek channel) are within the 100-year flood zone identified for the creek.The entire project area is within the 500-year flood hazard area and the potential E € Flood 'Zones AE and A, FEMA Flood Insurance Rate Map Panel 8683H dated August 28, 2008 (map number 06071C8683h), Q Federal Emergency Management Agency.

Although the project alignment is within this potential inundation area, occurrence of such an event is extremely remote. The dam has been engineered and constructed with the knowledge that the area is seismically active. Due to the unlikely possibility of darn m failure,the potential impact related to this issue is less than significant and no mitigation is required. L 0 VIII.i No Impact. The project alignment is not located near or adjacent to a lake or ocean;therefore, there is E no potential for inundation of the site by a seiche (a wave or oscillation of the surface of water in an �° enclosed or semi-enclosed basin)or tsunami. Because the project is not in close proximity to any large, a enclosed bodies of water (e.g., ocean, lake, or river) and is generally flat with no nearby mountainous o areas, potential impacts resulting from tsunamis, seiches, or mudflows are not anticipated to occur. In addition, the proposed flood control facilities are open at both ends and so would not create a new o potential seiche condition on their own.

The proposed project is located in an area that is predominantly low intensity industrial a with limited commercial uses, mainly along Waterman Avenue. There are scattered residential uses in the project area along Orange Show Road and Lena Road.

The applicable land use plan governing the project area is the City of San Bernardino General Plan(City of San Bernardino 2005). Other applicable regional plans developed by the Southern o California Association of Governments (SCAG) include the Regional Comprehensive Plan [SCAG N 2008b: (RCP)] and Regional Transportation Plan [SCAG 2008a: (RTP)]. The two public roads that are 0� part of the project alignment do not have any land use designations or zoning, while the Twin Creek C channel is designated Public Flood Control). The surrounding area is currently designated Industrial in O the General Plan and zoned IL (Light Industrial) and OIP (Office/Industrial Park) along Waterman Y Avenue. The proposed project would not conflict with any General Plan and zoning designations.Based on this information, the project is consistent with the General Plan and applicable regional plans, V therefore impacts in this regard are less than significant and no mitigation is required. H IX.c. No Impact. The project alignment is located in an urban area that is not within an established habitat o conservation plan or natural community conservation plan.

The proposed project would also not result in the loss of a locally-important mineral resource Cn recovery site. No mineral extraction activities occur on site. Because of the size and location of the CD project alignment,and the absence of any identified on-site mineral resource,development of the project alignment would not result in the loss of availability of a known mineral resource or a locally important mineral resource recovery site.

The project alignment is located in an area of the City that has existing scattered residences but is slowly developing with industrial uses. The City specifies o the maximum acceptable exterior community noise equivalent level (CNEL) for industrial uses in the c°vh° City shall not exceed 75 decibels (dB) while interior noise levels shall not exceed CNF,L 72dB. The CNEL is a 24-hour A-weighted average sound level from midnight to midnight obtained after the addition of 5 decibels(dB)to sound levels occurring between 7:00 p.m.and 10:00 p.m. and 10 dB to the uJ sound levels occurring between 10:00 p.m. and 7:00 a.m.' The 5 dB and 10 dB penalties added to the evening and nighttime hours account for the added sensitivity of humans to noise during these time periods. Based on noise analyses prepared for similar projects, noise from construction equipment a typically generates approximately 68 dB at 100 feet from the area where it operates. if two pieces of equipment are used, the "typical" construction noise measurements of the maximum hourly average in noise levels are expected to be approximately 72 dB at 100 feet from the point of origin. These noise sources would decrease at a rate of 6 dB per doubling of distance; therefore, at 200 feet, construction Q noise would decrease to 66 dB;at 400 feet,the noise would decrease to 60 dB;etc. B t X W C y E U City of San Bernardino General Plan,Chapter 14,Noise Element,November 1,2005, Q Twin Creek Orange Show Road Storm Drain Project 49 Packet Pg.276 5.J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY The nearest noise-sensitive uses to the proposed project are approximately sixteen existing 0 residences along the north side of Orange Show Road and along Lena Road, Table G shows the a estimated noise levels for various pieces of equipment that will likely be used on the proposed project = alignment. @ 0 E Table G—Typical Maximum Construction Equipment Noise Levels 0 RngoIluxaoium Sound SuggestedlVlIumurn Sound e� 1Neasu da 50 I:evel forA�na >rs�at 50 ft .

M Based on the Suggested Maximum Sound Level for Analysis at 50 feet (dBA) column in "fable G, the maximum noise level generated by scrapers is assumed to be 87 dBA at 50 feet. The maximum noise level generated by this equipment is approximately 86 dBA at 50 feet. Combined, these activities occurring at the same time in the active construction area would result in approximately 91 dBA at a distance of 50 feet. r ._ Existing residences in the vicinity of the project area may be subject to short-term, intermittent noise ° d generated by on-site tenant improvement activities. The closest residence in the vicinity of`the project a, area is located oil the north side of Orange Show Road east of Waterman Avenue,approximately 40 feet in from the project boundary,that would be subject to short-term noise reaching 91 dBA L,,,; generated by Q construction activities near the southern boundary of the project alignment.To prevent significant short- term noise levels at local residences,construction on the project alignment will need to be limited to the t City's permitted work hours, which are between the hours of 7:00 a.m. and 10:00 p.m. on weekdays and w weekends. In addition, the following measure is proposed to help assure local residents will not experience significant noise impacts during construction: W E NOIA During any project construction work within 200 feet of an existing residential property, U temporary noise reduction fencing shall be installed around the project work area or within the Q City right-of-way adjacent to the affected residential property or properties for the duration of Twin Creek Orange Show Road Storm Drain Project 50 Packet Pg.277 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r construction in that area.The fencing shall be constructed of plywood with a total thickness of I to 1.5 inches,or a sound blanket wall may be used.If sound blankets are used,they must have a a Sound Transmission Class(STC)rating of 27 or better. c L Based on the nature of the project,there will be essentially no long-term noise impacts other than from occasional channel maintenance vehicles and activities. As long as project activities are limited to the E hours and other requirements of the City's Noise Ordinance, and Mitigation Measure NOI-1 is cYA implemented as recommended,there will be no noise significant impacts during construction. -o M 0 Xl.b Less than Significant Impact with Mitigation. Vibration refers to groundbome noise and perceptible W motion. As with noise, ground vibrations can be described by amplitude and frequency. Vibration o amplitude is characterized by its displacement, velocity, and acceleration. Displacement is the distance U) that soil particles travel from their original location as a result of vibration, as measured in inches or m millimeters. Velocity is the speed of the soil particles measured in inches per second or millimeters per C second.Acceleration is the acceleration of the soil particles measured in inches per second per second or O millimeters per second per second. Particle velocity is the most commonly used vibration attribute used d to describe vibration. Table H presents the human reaction to various levels of peak particle velocity. d Vibrations also vary in frequency. Traffic vibrations generally range in frequencies from 10 to 30 hertz U (Hz), and tend to average around 15 Hz. As a point of reference, city buses often generate frequencies around 3 Hz at high vehicle speeds,due to their suspension systems. t3 L O w— Table H: Human Reaction to Typical Vibration Levels Vibration Level Peak a� Particle Velocity Z (inches/second) Human Reaction 0.0059-0.0188 Threshold of perception, possibility of intrusion. °a 0.0787 Vibrations readily perceptible. 0 0 0.0984 Level at which continuous vibrations begin to annoy people. 0.1968 Vibrations annoying to people in buildings. M 0.3937-0.5905 Vibrations considered unpleasant by people subjected to 00 continuous vibrations and unacceptable to some people walking on bridges. -a Source: Caltrans 1992. Gooundbome vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the motion may be discernable but without the effect associated with the — shaking of a building there is less of a reaction. Typical sources of groundbome vibration are heavier c construction activities (e.g., blasting, pile driving, and operating heavy duty earthmoving equipment), a� steel-wheeled trains, and occasional traffic on rough roads. In this case, most of the construction Cn activities will be less intense so the potential vibration impacts would be correspondingly less. Problems Q with groundborne vibration and noise from these sources are usually localized to areas within about 100 feet from the vibration source. When roadways are smooth,vibration from traffic, even heavy trucks, is _ rarely perceptible. It is assumed for this project that the roadway surface would be smooth enough that W groundborne vibration from street traffic would not exceed the impact criteria. However,trenching and c sub-surface construction proximate to any of the 16 existing residences along the project area may result in increased vibration impacts when construction is in the vicinity of the residences, especially those closest to Orange Show Road or Lena Road. Any groundborne noise or vibration would be short-term ca and occur only intermittently during grading and construction of the proposed facilities. However, the Q Twin Creek Orange Show Road Storm Drain Project 51 Packet Pg.278 I CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY Y V following measure is proposed to help assure that local residents do not experience significant vibration o impacts: a NOI-2 During trenching within 200 feet of an existing residential property, vibration levels will be L regularly measured at the closest adjacent residential property line to assure vibration levels do not exceed 0.2 inches per second which, according to Caitrans, is the level at which continuous E vibrations are annoying to people in buildings. If project-related vibrations exceed this threshold ° for more than one continuous hour on a given day, or intermittently for over a four-hour period a of time on a given day,alternative less intense construction methods shall be implemented(e.g., tY using smaller equipment or using larger equipment for shorter periods of time, etc.)to achieve the indicated performance standard.This measure shall be implemented to the satisfaction of the o City Engineer and only where project construction is within 200 feet of an existing residence N along the street portion of the project. aD _ XI.c No Impact. The project proposes no new land uses and so would not introduce additional residents or ca 0 workers into the area on a long-term basis. The project improvements will not create any new noise so �c ambient noise levels will remain the same after project implementation. Therefore, there is no impact 4) and no mitigation is required, v XI.d Less than Significant Impact. The addition of the proposed project to the project area, which is primarily industrial with scattered residential uses, would temporarily increase noise levels over those o that currently exists as a result of construction activities. During the construction phase of the project � there would be a temporary increase in noise levels that would be reduced by compliance with the p City's Noise Ordinance (Chapter 8.54 of the Municipal Code). With that, impacts would be less than a� significant and no mitigation is required. z XI.e No Impact. The nearest airport to the project alignment is San Bernardino International Airport(SBIA), °a located approximately 0.85 mile to the east at its closest point. As indicated in the City of San Q Bernardino's General Plan(Figure LU-4), the project alignment is not located within the SBIA's noise contours identified for this air facility. The project would not add any occupied uses or tall above- ground structures that would interfere with activities at the airport, and would not introduce new ; residents or employees into the project area.Therefore,there is no impact and no mitigation is required. 00 M XII.

The proposed project would construct only underground flood control improvements, and would not create any new land uses that would generate new population,residences,or employment that H would in turn generate additional traffic on city streets. During construction,there will be some amount o of traffic during peak hours as workers drive to and from the site, but overall traffic volumes would be — relatively low given the modest intensity of the proposed construction activities.

Z r Q. XV.c No Impact.The nearest airport to the project alignment is San Bernardino International Airport, located O approximately 0.85 mile northeast of the project alignment at its closest point. While the project Q alignment is located within the airport influence area of the SB1A, the nature and type of development °� proposed for the project alignment would not impact the frequency or pattern of air traffic at San Bernardino International Airport as it is a compatible use. Therefore, there would be no impact and no M mitigation is required. M XV.d Less than Significant Impact with Mitigation.The project will not generate any significant amount of -a additional traffic on City streets or increased road hazards over the long-term, but may result in temporary traffic delays or rerouting of traffic during construction in certain portions of the project area. in Therefore,the following mitigation measure is proposed: R TRA-1 Prior to construction of any street portion of the project, the prime contractor shall submit a Construction Traffic Mitigation Plan to the City for review and approval. The Plan shall outline c how construction traffic, parking, non-vehicular access, and other localized impacts from in project work will minimize traffic impacts on Orange Show Road and Lena Road. The Plan shall include signage, lane closures, use of signal persons, etc. to help reduce potential traffic `t impacts from project construction. This measure shall be implemented to the satisfaction of the M City Engineer. w In addition to TRA-1, the previous section VII.f recommended Mitigation Measure HAZ-2 which will help assure the project area will have adequate emergency access during all phases of project E construction. As long as adequate safety and traffic control precautions are taken, there should be no significant impacts related to roadway hazards, and no additional mitigation is required(see Item XV.e below regarding City access control measures). Q Twin Creek Orange Show Road Storm Drain Project 55 Packet Pg.282 CITY OF SAN BERNARDINO /ow- PLANNING DIVISION INITIAL STUDY a� XV.e. Less than Significant Impact with Mitigation. The previous section XVA recommended Mitigation a Measure TRA-1 which requires a Construction Traffic Mitigation Plan, and the previous section VILf = recommended Mitigation Measure HA7-2 which requires the project to maintain adequate emergency access during construction. The design, construction(or reconstruction), and maintenance of structure, roadways, and facilities must also comply with applicable City standards related to emergency access E and evacuation plans. Any construction activity that may temporarily restrict vehicular traffic would be r° required to implement adequate and appropriate measures to facilitate the passage of persons and a vehicles through/around any required road closures. Adherence to the recommended mitigation o measures and applicable City access control measures would reduce the potential impact related to this issue to a less than significant level,and no additional mitigation is required. XV.f Less than Significant Impact with Mitigation. As described above, the proposed project will not add d new land uses or generate new residents or employees who would need non-vehicular transportation c services or improvements. Project construction may temporarily restrict vehicular and non-vehicular access to the project area when work is being done along Orange Show Road or Lena Road. However, O 0 the previous section XVA recommended Mitigation Measure TRA-1 which requires a Construction w Traffic Mitigation Plan that includes non-vehicular access.Therefore, impacts in this regard will be less L) than significant and no additional mitigation is required.

The project must comply with Sections 404 and 401 of the Clean Water Act (CWA) in N terms of stormwater runoff quantity and quality that are discharged to this stretch of the Santa Ana a� River via Twin Creek. Mitigation Measure HYD-1 outlined in the previous Section VIII.a requires the r_ filing of a Notice of Intent with the Regional Water Quality Control Board consistent with CWA � requirements to protect water resources in this area. m a� In summary, the proposed project would not require any new water or wastewater connections for c i service, and subsequent permitting will assure compliance with regional water quality requirements, _ therefore,there would be no impacts and no mitigation is required. L 0 XVI.c Less than Significant Impact. The proposed project involves an expansion to the City's existing flood control system to accommodate future growth.Approvals of drainage features/improvements are subject o to review and approval by the City Engineering Department. As part of this process, all project-related drainage features would be required to meet the City's Operation & Maintenance Division standards. z The installation of project-related storm drain improvements would occur within an existing urbanized a. area and would be designed,installed, and maintained per City standards. Because the project would be 00 required to design and install drainage systems according to standards and provisions set forth by the Q City of San Bernardino, impacts related to this issue are anticipated to be less than significant (i.e., it (00i will actually be beneficial)and no mitigation is required. XVI.d No Impact. The proposed project does not trigger the requirement for preparation of a water supply 0 assessment(i.e., a development exceeding 500 residential units or equivalent) as established in Sections 10910-10912 of the California Water Code. See Item XVI.a-b above for more information. XVI.e No Impact.Please refer to response to Checklist Question XVI.a-b above. N XVI.f Less than Significant Impact with Mitigation. Demolition of existing flood control facilities will be required to construct the proposed project. Materials that can be reused will be recycled to the extent -v practical through the City's Refuse and Recycling Division, or through the County's Solid Waste c Management Division as appropriate.The City will provide solid waste collection services to the project in alignment through the City's Refuse and Recycling Division. Solid waste collection is a "demand- responsive" service and current levels can be expanded and funded through user fees. Non-recyclable Q solid waste from the proposed project would be collected and transported to the San Timoteo Sanitary a Landfill, located in the City of Redlands. These requirements are outlined in the following mitigation x measure: W UTL-1 During project construction, existing asphalt and other waste materials will be recycled or m reused onsite to the extent practical, in compliance with the requirements of City's Refuse and Recycling Division or the County's Solid Waste Management Division, as appropriate. Any Q Twin Creek Orange Show Road Storm Drain Project 57 Packet Pg.284 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r U materials that cannot be recycled or reused as part of this project will be disposed of in an appropriate manner.This measure shall be implemented to the satisfaction of the City Engineer. a c The San Timoteo Sanitary Landfill has a daily permitted throughput of 1,000 tons per day, a remaining i capacity of 11,360,000 cubic yards,and an estimated closure date of 2016.'Average daily throughput as o of 2011 is estimated at 690 tons/day. The volume of solid waste generated by the proposed project per E day represents 0.024 percent of the current permitted throughput at the San Timoteo Sanitary Landfill. ° As adequate daily surplus capacity exists at the receiving landfill, development of the proposed project would not significantly affect current operations or the expected lifetime of the landfill serving the o project area. With implementation of Mitigation Measure UTL-1, no significant solid waste disposal impact would occur and no additional mitigation is required. o t XVI.g Less than Significant Impact. The proposed project would be required to comply with applicable m elements of AB 1327, Chapter 18 (California Solid Waste Reuse and Recycling Access Act of 1991) and other applicable local, state, and federal solid waste disposal standards, thereby ensuring that the 0 solid waste stream to the San Timoteo Sanitary Landfill is reduced in accordance with existing 14 regulations. In addition, Mitigation Measure UTL-1 recommended in Section XVIX above will help m assure used asphalt will be recycled as part of this project. Otherwise, solid waste impacts are j considered to be less than significant.

No endangered or threatened species were identified on site during the biological resource survey. As stated in Section III, development of the proposed project would not cause a fish or wildlife population to drop below self-sustaining levels or restrict the r movement/distribution of a rare or endangered species. The proposed project would not affect any N threatened or endangered species or habitat. Potential impacts to migratory birds, the burrowing owl, jurisdictional drainage features, and nesting bird species would be mitigated to a less than significant F level with adherence to Mitigation Measures BIO-1 through BIO-3. Impacts to on-site biological as resources (Twin Creek channel) will be reduced to a less than significant level with adherence to the a� identified mitigation measures and subsequent state and federal permitting approvals. Development of the proposed flood control improvements would not result in the elimination of any Q identified archaeological or historical resources. There are no known unique ethnic or cultural values associated with the site,nor are there any religious or sacred uses associated with the project alignment. X Mitigation Measures CUL-1 and CUL-2 have been identified to mitigate potential impacts if W undiscovered subsurface cultural and/or paleontological resources are found during excavation m operations.Adherence to the measure identified would reduce potential impacts associated with cultural, E historic,or paleontological resources to less than significant levels. s U t0 Q Twin Creek Orange Show Road Storm Drain Project 59 Packet Pg.286 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY XVI.b Less than Significant with Mitigation. The proposed project alignment is located within an area has 0 been designated by the City for industrial and commercial uses. While short-term construction-related a air quality and noise impacts would result from construction of the proposed flood control c improvements,adherence to Mitigation Measures AIR-1,GCC-1,NOI-I and N0I-2 identified in this Initial Study would help these impacts remain at less than significant levels. Other impacts related to biological resources, geologic and soil conditions, hydrology and water quality, hazards and hazardous o materials, and archaeological/paleontological resources are similarly reduced to a less than significant level through the implementation of mitigation measures and the adherence to established City- mandated design and construction standards. Potential impacts related to water quality, hazardous o materials, and emergency access are addressed by Mitigation Measures HYD-1, HYD-2, HAZ-1, HAZ-2,and TRA-1,respectively. o The cumulative effects resulting from build out of the City's General Plan were previously identified in the General Plan EIR. The type, scale, and location of the proposed project is consistent with City's General Plan and zoning designation and is compatible with the pattern of development that has been approved for adjacent properties. Because of this consistency, the potential cumulative environmental Y effects of the proposed project would fall within the impacts identified in the City's General Plan EIR. P As no cumulative impact greater than that identified in the General Plan EIR would result from 0 construction of the proposed drainage improvements, so less than significant impacts are anticipated to = occur.

The project proponent shall ensure that construction equipment is properly maintained and 3 serviced to minimize exhaust emissions. N 2. The project proponent shall ensure that existing power sources are utilized where feasible via temporary power lines to avoid on-site power generation. C L 3. The project proponent shall ensure that construction employees be informed of ride-sharing O and transit opportunities. m 4. The project proponent shall ensure that any portion of the site to be graded shall be U prewatered to a depth of three feet prior to the onset of grading activities. 5. The project proponent shall ensure that twice daily watering of the site or other soil f' stabilization methods shall be employed on an ongoing basis after the initiation of any on- ° site grading activity. Portions of the site that are actively being graded shall be watered d regularly to ensure that a crust is formed on the ground surface, and shall be watered at the end of each workday. 0 Z 6. The project proponent shall ensure that all disturbed areas are treated to prevent erosion Q, until the site is constructed. ° 7. To reduce the potential for wind erosion,the project proponent shall ensure that landscaped o areas,if any,are installed as soon as possible. 8. The project proponent shall ensure that SCAQMD Rule 403 is adhered to, ensuring the cleanup of construction-related dirt on approach routes to the project alignment. M 9. The project proponent shall ensure that all grading activities are suspended during first and second stage ozone episodes or when wind speeds exceed 25 miles per hour. -a 10. Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 0.6 in u) (2 feet) of freeboard (vertical space between the top of the load and top of the trailer)in accordance with the requirements of California Vehicle Code(CVC) Section 23114. 11. Limit all on-site traffic speeds to 15 mph or less. c a� GCC-1 To the extent practical and to the satisfaction of the City, the following shall be En incorporated into the design and construction of the project: Q • Use locally produced and/or manufactured building materials for at least 10 percent of the construction materials used for the project. x • Use "Green Building Materials," such as those materials that are resource efficient, and w recycled and manufactured in an environmentally friendly way, for at least 10 percent of the m project. E • Limit unnecessary idling of construction equipment. A reduction in equipment idling would ° reduce fuel consumption,and therefore,GHG emissions. Q Twin Creek Orange Show Road Storm Drain Project 62 Packet Pg. 289 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY U • Maximize the use of electricity from the power grid by replacing diesel- or gasoline- 0 powered equipment during construction. This would reduce GIIG emissions because a electricity can be produced more efficiently at centralized power plants. c 'ca RI0-1 A pre-construction burrowing owl survey shall be conducted within 10 days prior to beginning of site grading in the event that burrowing owls occupy the site in the future. Surveys and E relocation, if applicable, shall be conducted between September l and January 31. It is 4° anticipated that the survey protocols will, at a minimum, reflect the standards of the CDFW '0 Staff Report on Burrowing Owl Mitigation(2012,as summarized below). 0 If burrowing owls are found on-site during the pre-construction surveys,they will be protected o in place through the use of buffer zones, visual screens, or other measures, while construction Cn Cn activities are occurring. The CDFW Staff Report on Burrowing Mitigation includes appropriate CD buffer zones based on the timing of construction that will be implemented, if needed. If occupied burrows are too close to proposed construction areas to allow for appropriate protection in place,a qualified biologist will discuss additional avoidance options with CDFW. �c m If needed,owls will be relocated by a qualified biologist from any occupied burrows that cannot v be avoided by project activities into adjacent suitable habitat. Suitable habitat is undeveloped land that can meet the burrowing owl's life cycle requirements(for both foraging and breeding) 3 and is not intended for development. Suitable habitat must be adjacent or near the disturbance site or artificial burrows will need to be provided nearby. Once the biologist has confirmed that the owls have left the burrow, burrows should be excavated using hand tools and refilled to prevent reoccupation. Owls shall be excluded from burrows using passive relocation techniques within the approved Z limits of disturbance and an appropriate buffer zone. This will be conducted by a qualified Q biologist by installing one-way doors in burrow entrances. The qualified biologist will also 00 determine whether creation of artificial burrows is necessary as part of the relocation effort. < 0 A Burrowing Owl Relocation Plan (Relocation Plan)prepared by a qualified biologist shall be submitted to the CDFW for review and approval prior to relocation of owls. The Relocation Plan shall describe proposed relocation and monitoring plans and shall include the number and o location(s)of occupied burrow sites and details on adjacent or nearby suitable habitat available M to owls for relocation. If no suitable habitat is available nearby for relocation, details regarding >� the creation of artificial burrows(numbers, locations, and type of burrows) shall be included in a the plan.The Relocation Plan shall also describe proposed mitigation to compensate for impacts to burrowing owls/occupied burrows within the project alignment. �a Y BI0-2 The Project applicant shall mitigate riparian/riverine habitat impacts in the Twin Creek Channel = at a minimum 1:1 ratio. If onsite mitigation is determined to be insufficient by the resource m agencies, the project applicant shall mitigate any residual onsite impacts to riparian/riverine = a� habitat through the purchase of mitigation credits at a ratio of 2:1.The mitigation credits will be in purchased through the Inland Empire Resource Conservation District (IERCD) to ensure high Q quality habitat is preserved/restored within the same watershed as the impact area. t BIO-3 If project activities are planned during the avian nesting season (approximately February 1 w through August 31), nesting bird surveys shall be conducted within three days prior to disturbance to ensure birds protected under the MBTA are not disturbed by construction-related d activities such as noise and increased human presence. Any active nests detected in the area E shall be flagged and an appropriate buffer around the nest location will be established, as w Q Twin Creek Orange Show Road Storm Drain Project 63 Packet Pg.290 S.J.e CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY ^ determined by the CDFW.The buffer area is to be avoided until the nesting cycle is complete or o it is determined by the biologist that the nest has failed. a c CUL-1 If cultural resources (archaeologic or historic) are discovered during project excavation activities, a qualified archaeologist and/or historian shall be retained to assess the nature and significance of the find,diverting construction excavation if necessary.The archaeologist and/or E historian shall have the authority to redirect ground-disturbing activities in the vicinity of the rn find until the nature and extent of the find can be evaluated. Any such resource uncovered M during the course of project-related grading shall be recorded and/or removed per applicable o guidelines, in consultation and cooperation with San Bernardino County Museum staff and 0� appropriate Native American tribal representatives or the County Historical Society. o CUL-2 If paleontological resources are discovered during grading, a qualified paleontologist will be retained to evaluate the resource and then monitor the remaining ground-disturbing activities. c The qualified paleontologist shall have the authority to redirect ground-disturbing activities in O the vicinity of the find until the nature and extent of the find can be evaluated. Any such resource uncovered during the course of project-related grading shall be recorded and/or removed per applicable guidelines, in consultation and cooperation with San Bernardino County Museum staff.

Land uses in the area adjacent to the project site are mainly 0a industrial with some commercial on the west end and scattered rural residences(approx. 16 units) Q along Orange Show Road and Lena Road. 0 Q Construction Emissions.Air quality impacts could occur during construction.Major sources of ch emissions during demolition,trenching,and construction include exhaust emissions from construction CD w vehicles and equipment and fugitive dust generated by construction vehicles and equipment traveling over exposed surfaces,as well as by soil disturbances from trenching. Exhaust emissions during -a activities envisioned on site would vary as construction activity levels change. 0 r N The analysis conducted here assumes a worse-case schedule as shown in Table A.It is assumed that there would be no overlap in emissions from different phases of construction.

N Local Significance Thresholds. In addition to the above regional emissions analysis,the SCAQMD FU CEQA Handbook requires an evaluation of how construction emissions may affect"sensitive receptors"like residents,young children,the elderly, etc.during construction using localized -a significance thresholds(LSTs)t.LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard,and are developed based on the ambient concentrations of that pollutant N for each source receptor area and distance to the nearest sensitive receptor. There are existing Q residential uses approximately 85 ft from the project site. Due to constraints of the project site configuration and the anticipated construction schedule,the project is not expected to disturb more x than 1 ac on a daily basis.However to be conservative this analysis uses the LST levels for 2 ac. W Table C shows that the project on-site emissions would be lower than the appropriate SCAQMD LST ry E ' From the SCAQMD website,www.agmd.gov/home/regulations/cega/air-quality-analysis- handbook/localized-significance-thresholds.

In order to fully control construction-related air quality impacts,the City will require the preparation and approval of a Dust Control Plan to be reviewed and approved by the Public Works Division. In addition,the project proponent shall incorporate the following standard conditions into the project.All air pollutant emissions would be below the daily thresholds Z established by the SCAQMD without mitigation. C SC-1 The project shall comply with the requirements of SCAQMD Rules 402 and 403, o Fugitive Dust, which require the implementation of Reasonable Available Control (D Measures (RACM) for all fugitive dust sources, and the AQMP, which identifies Best Available Control Measures(BACM)and Best Available Control Technologies o (BACT) for area sources and point sources, respectively. This would include but M would not be limited to the following actions: a 1. The project proponent shall ensure that construction equipment is properly maintained and serviced to minimize exhaust emissions. in 2. The project proponent shall ensure that existing power sources are utilized where r feasible via temporary power lines to avoid on-site power generation. _ 3. The projeci proponent shall ensure that construction employees be informed of = ride-sharing and transit opportunities. U) 4. The project proponent shall ensure that any portion of the site to be trenched shall a be prewatered to a depth of three feet prior to the onset of trenching activities. r2 5. The project proponent shall ensure that twice daily watering of the site or other x soil stabilization methods shall be employed on an ongoing basis after the W initiation of any on-site trenching activity. Portions of the site that are actively being trenched shall be watered regularly to ensure that a crust is formed on the 0) ground surface,and shall be watered at the end of each workday. w Q 1116/15(UTHE,1401 Twin Creek Orange Show\Technical Studics\Construction AQ Memo 1-12-15.docx) 3 Packet Pg.297 LSA ASSOCIATES. INC.. Y V O L 6. The project proponent shall ensure that all disturbed areas are treated to prevent erosion until the site is constructed. L 7. To reduce the potential for wind erosion,the project proponent shall ensure that landscaped areas are installed as soon as possible. o Y 8. The project proponent shall ensure that SCAQMD Rule 403 is adhered to, N ensuring the cleanup of construction-related dirt on approach routes to the project c site. 9. The project proponent shall ensure that all grading activities are suspended 0 during first and second stage ozone episodes or when wind speeds exceed 25 cn miles per hour. 10. Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at O Ieast 0.6 m (2 feet) of freeboard (vertical space between the top of the load and Y top of the trailer)in accordance with the requirements of California Vehicle Code (CVC)Section 23114. t i 11. Limit all on-site traffic speeds to 15 mph or less. _ L O Summary.By conforming to the construction Standard Conditions mandated by the SCAQMD and listed above in SC-1,the planned construction of the proposed project would not create air emissions p that would exceed any of the SCAQMD daily emissions thresholds nor any of the SCAQMD LST thresholds.Thus,the air emissions during construction would be less than significant and no z Y mitigation is necessary. o v Q 0 N d Ce M O O M A 3 co''Y^^ Y d Q .Q X W Y E V Q 1/16/15(RATHE1401_Twin Creek Orange Show\Teehnical SWiesTonstruction AQ Memo 1-12-15.doex) 4 PAdket:Pg 29 CITY OF SAN BERNARDINO PLANNING DIVISION INITIAL STUDY r APPENDIX B o L Biological Resources Assessment and Permitting Materials 0 E L 0 v/ 0 3 0 s m 0 L 0 Q L V L 0 4-� V d 0 d Z Q 0 Q 0 N d M O O Cl) A .II 0 r N tC d _ _O t x W _ m E ca a Twin Creek Orange Show Road Storm Drain Project Packet Pg.299` U.S. Army Corps of Engineers South Pacific Division M L a Nationwide Permit Pre-Construction Notification (PCN) Form This form integrates requirements of the U.S.Army Corps of Engineers Nationwide Permit Program within the South Pacific Division (SPD),including General and Regional Conditions.

BIOLOGICAL RESOURCES BIO-l: A pre-construction burrowing owl survey shall be conducted within 10 days prior to beginning of site grading in the event that burrowing owls occupy the site in Y the future. Surveys and relocation, if applicable, shall be conducted between d September 1 and January 31. It is anticipated that the survey protocols will, at a minimum, reflect the standards of the CDFW Staff Report on Burrowing Owl 3 Mitigation(2012, as summarized below). L 0 If burrowing owls are found on-site during the pre-construction surveys, they will be protected in place through the use of buffer zones, visual screens, or other measures, while construction activities are occurring. The CDFW Staff Report on z Burrowing Mitigation includes appropriate buffer zones based on the timing of o construction that will be implemented, if needed. If occupied burrows are too Q close to proposed construction areas to allow for appropriate protection in place, a 0 qualified biologist will discuss additional avoidance options with CDFW. If needed, owls will be relocated by a qualified biologist from any occupied o burrows that cannot be avoided by project activities into adjacent suitable habitat. Suitable habitat is undeveloped land that can meet the burrowing owl's life cycle requirements (for both foraging and breeding) and is not intended for a) 0 development. Suitable habitat must be adjacent or near the disturbance site or a artificial burrows will need to be provided nearby. Once the biologist has _ confirmed that the owls have left the burrow, burrows should be excavated using o hand tools and refilled to prevent reoccupation. E 0 Owls shall be excluded from burrows using passive relocation techniques within the approved limits of disturbance and an appropriate buffer zone. This will be conducted by a qualified biologist by installing one-way doors in burrow �° entrances. The qualified biologist will also determine whether creation of artificial o burrows is necessary as part of the relocation effort. N A Burrowing Owl Relocation Plan (Relocation Plan) prepared by a qualified biologist shall be submitted to the CDFW for review and approval prior to 2 relocation of owls. The Relocation Plan shall describe proposed relocation and Y monitoring plans and shall include the number and location(s) of occupied burrow a sites and details on adjacent or nearby suitable habitat available to owls for relocation. If no suitable habitat is available nearby for relocation, details 3 regarding the creation of artificial burrows (numbers, locations, and type of ~ burrows) shall be included in the plan. The Relocation Plan shall also describe Q� proposed mitigation to compensate for impacts to burrowing owls/occupied burrows within the project alignment. m r BIO-2: The Project applicant shall mitigate riparian/riverine habitat impacts in the Twin Creek Channel at a minimum 1:1 ratio. If onsite mitigation is determined to be w insufficient by the resource agencies, the project applicant shall mitigate any residual onsite impacts to riparian/riverine habitat through the purchase of E mitigation credits at a ratio of 2:1. The mitigation credits will be purchased R w Packet Pg.320 Mitigation Monitoring and Reporting Program Twin Creek Orange Show Road Storm Drain Project Page 6 0 through the Inland Empire Resource Conservation District (IERCD) to ensure U) high quality habitat is preserved/restored within the same watershed as the impact area. P 0 9 BIO-3: If project activities are planned during the avian nesting season (approximately February 1 through August 31), nesting bird surveys shall be conducted within v three days prior to disturbance to ensure birds protected under the MBTA are not 3 disturbed by construction-related activities such as noise and increased human L presence. Any active nests detected in the area shall be flagged and an appropriate ° buffer around the nest location will be established, as determined by the CDFW. o The buffer area is to be avoided until the nesting cycle is complete or it is determined by the biologist that the nest has failed. z a 0 IMPLEMENTATION AND VERIFICATION 0 N N Planning staff and/or City Inspectors shall verify implementation of the above mitigation measures. c 00 M r V COMPLIANCE RECORD o L a When Required: The verification shall be completed prior to issuance of a grading permit. 0 E L WRITTEN VERIFICATION PREPARED BY: r° 0 Of DATE PREPARED: 0 s Cn W a> c co L 0 L U c h m .Q X w r c E U r Q Packet Pg. 321 5.J.f Mitigation Monitoring and Reporting Program Twin Creek Orange Show Road Storm Drain Project Page 7 o IV.
