Backl!round: On October 4, 2004, the Mayor and Common Council adopted an Agreement with San Manuel Band of Mission Indians for public improvement projects for tribal project impacts. City staff determined that the design of street. storm drain, traffic signal and soundwall improvements along Victoria Avenue from Highland Avenue to Lynwood Avenue was a project that can best be accomplished by a consultant. On January 10,2005, the Mayor and Common Council approved an Agreement for Professional Services with Engineering Resources of Southern California to provide Civilrrraffic Engineering Services for the Design of Street, Storm Drain, Traffic Signal and Sound Wall Improvements along Victoria Avenue from Highland Avenue to Lynwood Avenue. On February 16,2006, the Development/Environmental Review Committee independently reviewed, analyzed, and exercised independent judgement in reviewing the Initial Study and voted to release the Initial Study and proposed Mitigated Negative Declaration for public review in compliance with Section 21092.3 of the Public Resources Code. The Notice of Intent to adopt a Mitigated Negative Declaration was filed with the San Bernardino County Clerk of the Board of Supervisors and the Governor's Office of Planning and Research and advertised in The Sun newspaper on February 20, 2006, with a public review and comment period from February 21, 2006 through March 23, 2006. The Initial Study was available for public review at the Development Services Department, the Feldheym Central Library, and the City of San Bernardino web site. Comments were received from the City of Highland and San Bernardino County Flood Control District. The project will be constructed in two phases as follows: Phase I: All work on Victoria Avenue from just south of 28th Street north to north of Lynwood Drive including sound wall and median island construction, sidewalk replacement, landscaping installation, restriping and installation of new traffic signals at the intersections of Mirada Road and Lynwood Drive. Curb, gutter sidewalks and a traffic channelizing island will be constructed on Lynwood Drive. Phase 2: All work on Victoria Avene from Just south of 28th Street south to Highland Avenue including street widening, paving, median and sidewalk construction, landscaping and street light installation, overhead utility undergrounding, new fence and concrete drainage swale construction adjacent to the Patton Flood Control Basin, pavement restriping, traffic signal modification at the intersection of Highland Avenue and Victoria Avenue and installation of a new traffic signal at the intersection of Date Street and Victoria Avenue. The road improvements on the south side of Highland Avenue between Victoria Avenue and Robinson Road would be included in Phase 2. The Plans. SpeCifications and Cost Estimate for Phase I work are nearly complete. Staff desires that the documents be completed so that Phase I construction can begin as soon as possible. Financial Impact: None. 2 04/05/20064:41 PM CITY OF SAN BERNARDINO REQUEST FOR COUNCIL ACTION STAFF REPORT - Continued Recommendation: 1.

The purpose of the Initial Study is to determine whether or not a proposal, not exempt from CEQA, qualifies for a Negative Declaration or whether or not an Environmental Impact Report (EIR) must be prepared. 1. Project Title: Victoria Avenue Street Improvement and Beautification Project 2. Lead Agency Name: Address: City of San Bernardino 300 North "D" Street San Bernardino, CA 92418 3. Contact Person: Phone Number: Mark Lancaster, Deputy Director/City Engineer (909) 384-5057, ex!. 3305 4. Project Location (Address/Nearest cross-streets): Victoria Avenue between Highland Avenue and Lynwood Drive, Lynwood Drive west of Victoria Avenue, and Highland Avenue between Victoria Avenue and Robinson Road. 5. Project Sponsor: Address: City of San Bernardino 300 North "D" Street San Bernardino, CA 92418 6. General Plan Designation: N/A 7. Description of Project (Describe the whole action.involved, including, but not limited to, later phases of the project and any secondary, support, or offsite feature necessary for its implementation. Attach additional sheets, if necessary): The proposed project is street improvements to Victoria Avenue between Highland Avenue and Lynwood Drive that will include aesthetic, traffic flow and noise attenuation modifications. Figure 1 shows the Regional Location and Figure 2 is a Vicinity map. The project will include roadway widening between Highland Avenue and 28th Street to provide two 12-foot-wide lanes in each direction separated by a raised median except at street intersections. New traffic signals will be installed at the intersections of Victoria Avenue, Lynwood Drive, and Mirada Road. A traffic signal will also be installed at Victoria Avenue and the access road into Patton State Hospital (PSH) (Date Street). The existing signal at the intersection of Victoria Avenue and Citrus Street will not be modified. The existing signal at Highland Avenue and Victoria Avenue will be modified to accommodate the double left-turn lane for eastbound Highland Avenue to northbound Victoria Avenue. The signal to be located at the intersection of Victoria Avenue and Date Street will operate from 6 a.m. to 6 p.m., Monday through Friday and will show green for northbound and southbound traffic on Victoria Avenue at other times. Implementation of this signal will require a right-of~ entry onto Patton Hospital to install traffic signal sensors. ER-073/iMla! Study IS 1 CITY .OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY Sound attenuation walls will be installed along all portions of Victoria Avenue that currently abut existing residential development (both sides of Victoria Avenue between just south of 28th Street and Lynwood Drive and westerly on the south side of Lynwood Drive i:270 feet). Sound wall installation will be designed and constructed to reduce road noise to within the City standard of 65 dB CNEL for outdoor usable space. Existing walls will be left in place. Sidewalks along Victoria Ave between 28tt1 Street and Lynwood Drive will be reconstructed in a meandering pattern in coordination with the sound wall construction. Sidewalks along the remainder of the project area will be installed or reinstalled except where construction activities may not impact existing sidewalks on the east side of Victoria Avenue just north of Highland Avenue adjacent to the San Manuel Casino parking area. Landscaping will be installed behind the curbs along the length of the project and in the median where the width is greater than 3 feet. Existing trees along both sides of Victoria Avenue will be removed and replaced. Existing storm drain facilities will be modified to accommodate road improvements or relocated including a 24-inch culvert north of PSH at Date Street and an 18-inch culvert located south of the PSH Date Street entry. Existing overhead utilities will be placed underground as part of the project and new street lighting will be installed south of 28th Street. The portion of the project adjacent to the Patton Basin will require acquisition of 16 feet of additional right-of-way on the west side of Victoria Avenue from the San Bernardino County Flood Control District (Patton Basin). The additional right-of-way will allow in the construction of new concrete curb, gutter, sidewalk and AC paving to accommodate road widening. An existing dirt swale outside the proposed right-of-way along the Patton Basin will be concrete-lined and a perimeter fence will be replaced along the existing Patton Basin. In addition to the above improvements, the City is also proposing to acquire additional right-of-way along the south side of Highland Avenue between Victoria Avenue and Robinson Road. This additional right-of-way will allow the construction of a new right-turn lane from eastbound Highland Avenue onto southbound Victoria Avenue. Improvements to be installed include new pavement, curb, gutter and sidewalk and are shown on Figure 3. These road improvements will, besides providing the right-turn lane, also better align eastbound lanes on Highland Avenue east and west of Victoria Avenue by aligning the proposed curb and pavement with the existing curb lines on the south side of Highland Avenue west of Robinson Road and east of Victoria Avenue. Acquisition of the additional right-of-way and construction of the proposed improvements will result in the demolition of three small, occupied residential units adjacent to Highland Avenue. The proposed road improvements on the south side of Highland Avenue will be constructed if the needed right-af-way can be acquired. If the needed right-of-way cannot be acquired and constructed, no change in the road improvements proposed on Victoria Avenue will result. It should also be noted that the City of Highland is considering widening the north side of Highland Avenue from Victoria Avenue to the existing flood control basin located westerly of the intersection. Additionally, the City of Highland is proposing to construct a right-turn lane on southbound Victoria Avenue onto westbound Highland Avenue. While these improvements benefit traffic on Highland Avenue, the City of San Bernardino's project is not dependent on the City of Highland's anticipated improvements. The City of San Bernardino can construct its proposed improvements and achieve its goals of improving traffic flow aesthetics and noise levels on Victoria Avenue regardless of whether or not the City of Highland proceeds with its planned road improvements. The two potential projects are independent of each other and neither are reliant on the other to achieve their individual goals. E~-073!lnrtlal Study IS 2 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY The project will be constructed in two phases as follows: Phase 1: All work from just south of 28th Street north to Lynwood Drive including sound wall and median island construction, sidewalk replacement, landscaping installation, pavement match- up and restriping and traffic signals intersections with Mirada Road and Lynwood Drive. Curb, gutter, sidewalks and a traffic channelizing island will be constructed on Lynwood Drive. Pavement match-up and striping will also be provided on Lynwood Drive. Figure 5 shows the location of Phase 1 improvements. Phase 2: All work from just south of 28th Street south to Highland Avenue including street widening, paving, median and sidewalk construction, landscaping and street light installation, utility undergrounding, fence and concrete drainage swale construction adjacent to the Patton Flood Control Basin, pavement restriping, traffic signal modification at the intersection of Highland Avenue and Victoria Avenue, and installation of a traffic signal at the intersection of Date Street and Victoria Avenue. The road improvements on the south side of Highland Avenue would be included in Phase 2. Figures 3 and 4 show the location of Phase 2 improvements. It is forecast that Phase 1 will take about 5 months to complete and Phase 2 will require about 6 months. Phase 2 will begin after Phase 1 is completed. 8. Surrounding Land Uses and Setting: Victoria Avenue currently conveys traffic via one lane in each direction between Highland Avenue to Mirada Road and via two lanes in each direction between Mirada Road and Lynwood Drive. A central turn lane begins just south of the existing signal at Citrus Street and continues north to Lynwood Drive. There are no access drives along Victoria Avenue north of Citrus Street except for the streets, so portions of the turn lane are not currently used. The existing intersection of Lynwood Drive and Victoria Avenue is controlled by stop signs on both streets. No other intersections along the project are controlled by stop signs on Victoria Avenue. An existing perimeter fence adjacent to residential development will remain in place after implementation of the project. Existing zoning along the project alignment is residential suburban along the residential development, public facility where PSH is located, public flood control where the flood control basin is located, and general commercial where the San Manuel Parking lot is located at the intersection of Highland and Victoria avenues. The land that would be acquired to expand the right-of-way of Victoria Avenue is zoned public flood control. The land along the south side of Highland Avenue is designated for General Commercial and is partially used for residential purposes in the City of Highland.

The proposed project is designed to improve the aesthetic qualities of Victoria Avenue by increasing landscaping along the right-of-way both within roadway medians and behind the curb. Sidewalks will be constructed in an aesthetically pleasing meandering design, and utilities that are currently above ground will be placed underground as part of the proJect. According to the City's Revised General Plan, the portion of State Route 30 south of State Route 330 and State Route 330 are the only highways that are designated as Eligible Scenic Highways within the City limits. The project area is not visible from either of these highway segments. No adverse effect on a scenic vista or the visual character of the area will result. No impacts to scenic resources such as trees, rock outcrop pings or historic buildings will result. The project is designed to improve the visual character of the project area. No mitigation is required. d. The following policies are discussed in the City's General Plan EIR: Policy 2.2.2: Require new uses to provide mitigation or buffers between existing uses where potential adverse impacts could occur, including, as appropriate, decorative walls, landscape setbacks, restricted vehicular access, enclosure of parking structures to prevent sound transmission, and control of lighting and ambient illumination. Policy9.6.5 : Encourage and promote the use of energy-efficient (U.S. Department of Energy "Energy Star" or equivalent) lighting fixtures, light bulbs, and compact fluorescent bulbs in residences, commercial, and public buildings, as well as in traffic signals and signs where feasible. (LU-1) Residences occur along the northern portion (Phase 1) of the alignment. Street lighting exists along Victoria Avenue and this project will not substantially alter the existing condition. Compliance with the above General Plan policies and City street lighting standards are considered adequate mitigation for potential lighting impacts. No further mitigation is required.

The proposed project is located within the South Coast Air Basin (SCAB). The South Coast Air Quality Management District (SCAQMD) has jurisdiction over air quality issues and regulations within the SCAB. The SCAQMD has published its CEQA Air Quality Handbook (CEQA Handbook) that identifies threshold values for emissions to assist local agencies in determining if a project's emissions could pose a significant threat to air quality and air quality standards. These construction thresholds of significance are: ROC (Reactive Organic Compounds) NOx (Nitrogen Oxides) CO (Carbon Monoxide) PMlO (small particle dust) SOx (Sulphur Oxides) 75lbs/day 100 Ibs/day 550 Ibs/day 150 Ibs/day 150 Ibs/day A quarter year comprises 65 working days, not 91 days. or or or or or 2.5 tons/quarter 2.5 tons/quarter 24.75 tons/quarter 6.75 tons/quarter 675 tons/quarter Components of each phase of the development will be constructed separately. Phase 1 is projected to take about 5 months to complete. Activities include some demolition, AC removal, the construction of new sound walls, the construction of curb and sidewalk,landscaping, some new AC paving, and subgrade preparation, and ER.073ilnrtlal Study IS 8 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY the construction of medians. These activities will occur at different times during the anticipated 6-month construction period. Because SCAQMD utilizes daily and quarterly construction emission thresholds to determine the significance of these emissions, this document will evaluate the emissions associated with the worst case day. Based on preliminary construction schedules, it is forecast that the worst case days will occur in month 2 of construction. At that time on a given day, several construction activities will be ongoing. These include emissions from the following: (10) worker commute trips (22) material delivery trips (pipe, concrete, sound wall panels, and other materials) (1 ) boom truck (1) small trencher (1) auger Due to the project's location in an urbanized area with ready access to materials and employees, it is forecast that delivery and commute trips will average about 30 miles roundtrip or a total of about 1,050 miles on a given day. Using EMFAC 2002 emission factors for on-road vehicles, emissions associated with the above trips are provided in Table 111-1. Emission calculations are provided in Appendix A of this document.

Figure NRC-1 of the City's General Plan shows that the site is not within designated critical habitat for the California gnatcatcher, the San Bernardino kangaroo rat or the Delhi Sands flower-loving fly. The project area is entirely disturbed and as such provides no sUitable habitat for sensitive species.

The Area of Potential Effect (APE) of this project contains already developed land (roads, flood control facilities, etc.). The potential for surface or near surface resources to occur is considered highly unlikely. To determine if any cultural resources are known or suspected of occurring onsite, the consulting firm of CRM TECH had the Archaeological Information Center at the San Bernardino County Museum perform a records search to determine if any resources are known to occur within or near the APE. Additionally, CRM TECH conducted historical background research of available published literature and maps of the area. CRM TECH also contacted the Native American Heritage Commission and the San Manuel Band of Mission Indians due to the project's location near the San Manuel Reservation. According to records on file at the Archaeological Information Center, portions of the APE may have been included in various previous cultural resources studies along the project route. As a result of these and other similar studies in the vicinity, a total of five historical/archaeological sites were previously recorded in close proximity to the APE Among these were a Native American village site (CA-SBR-2282/H), a segment of the Santa Fe Railroad's Kite-Shaped Route (CA-SBR-6847H), two irrigation ditches of uncertain historic background (CA-SBR-9996H and -9997H), and the Patton State Hospital (P36-017694). CA-SBR-2282/H encompassed a large area near the northern end of the APE and on the southern edge of the San Manuel Indian Reservation. From the 1930s to the 1970s, a number of structures, archaeological features, and artifacts attributed to the San Manuel Band of Mission Indians. including a ceremonial house and a ER.073/lnitlal Study IS 12 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY cemetery, were noted in that area. The Kite-Shaped Route, an extremely popular excursion route on the Atchison, Topeka and Santa Fe Railway during the 1890s-191 Os, is known to have crossed the southern portion of the APE, but the rail line at this location was removed nearly 40 years ago. The Patton State Hospital, which was established in 1890 and has been previously determined eligible for listing in the National Register of Historic Places, and the two irrigation ditches, both probably dating to the 1880s- 1890s. were recorded on the east side of Victoria Avenue. While the hospital grounds clearly lie outside - albeit adjacent to - the APE, the precise locations of the two ditches at CA-SBR-9996H and -9997H in relation to the APE were unclear from the records search results. Outside the APE but within a one-mile radius, AIC records show more than 20 previous cultural resources studies covering various tracts of land and linear features. At least 40 other archaeological sites, isolates, or historic-period buildings have been identified within the scope of the records search, including several other early irrigation works, early 20'" century residences and building remains, and a total of 25 buildings belonging to the Patton State Hospital. None of these sites, isolates, or buildings was found in the immediate vicinity of the APE, and thus none of them requires further discussion or investigation. CRM TECH performed a field survey of the APE. The results of the field survey confirmed that the entire Patton State Hospital compound (P36-017694) is located outside the APE, and no archaeological features or artifacts associated with the Native American village site (CA-SBR-2282/H), the Kite-Shaped Route (CA-SBR-6847H), or the irrigation ditch recorded as CA-SBR-9996H were found at or near their reported locations. The portion of CA-SBR-2282/H lying nearest to the APE is now occupied by a parking lot at the San Manuel Indian Casino, and it is clear that all railroad-related features at CA-SBR-6847H have been removed since that segment of the line was abandoned in 1967. A closer inspection at the location of CA-SBR-9996H revealed that the site was well outside the APE, in an area that is now part of another paved parking lot for the San Manuel Indian Casino. The other ditch previously found in that area, recorded as CA-SBR-9997H, has evidently been converted into an underground pipeline under the same parking lot. However, the northerly extension of that ditch, which is not included in the site record for CA-SBR-9997H, remains in existence on the western edge of the Patton State Hospital grounds, just outside the APE. During the survey, another ditch, which appears to date to the historic period but has not been previously noted, was found crossing the APE approximately 150 feet south of the intersection of Victoria Avenue and Mirada Street. The ditch is constructed of coarse-grained, board-formed concrete, and measures 50 inches wide and 41 inches deep, with 4-inch thick walls. It traverses east-west underneath Victoria Avenue and connects to an underground storm drain on the west side of the street before apparently turning south into an underground pipeline. On the east side of Victoria Avenue, the ditch continues east in an open canal that appears to be in its original state. Based on historic maps referenced above, this ditch has apparently been present at the current location since at least the 1930s. However. minor irngation or drainage canals like this are among the most frequently encountered cultural features in rural and formerly rural areas throughout southern California. Unlike the well-documented major irrigation works, the historical background of such minor ditches, canals, or flumes is often unclear and difficult to ascertain, and they are unlikely to be closely associated with persons or events of recognized historic significance. As a minor, ubiquitous, and fragmented element of the historic infrastructure, the ditch observed during the field survey is not considered a potentially significant cultural resource, and requires no further study. No other features. sites. or artifacts more than 50 years of age were encountered during the survey, nor were any historic-period buildings, structures, or objects found within the APE. As stated above, the entire APE, lying ER-D73!lnrtfal Study IS 13 ,.. CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY mostly within existing public rights-of-way, has been extensively disturbed in the past. The portion of the APE lying outside the current right-of-way boundaries is located between Victoria Avenue and a series of flood- control/percolation basins, also on heavily disturbed soil, and thus demonstrates little potential for intact archaeological remains. Regarding the proper criteria of historical significance, CEQA guidelines mandate that "a resource shall be considered by the lead agency to be 'historically significant' if the resource meets the criteria for listing on the California Register of Historical Resources" (Tille 14 CCR S15064.5(a)(3)). A resource may be listed in the California Register if it meets any of the following criteria: (1) Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage. (2) Is associated with the lives of persons important in our past. (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values. (4) Has yielded, or may be likely to yield, information important in prehistory or history. (PRC S5024.1(c)). In summary of the research results discussed above, the present study has established that a total of five historical/archaeological sites were previously recorded in close proximity to the APE, but three of the sites, P36-017694, CA-SBR-9996H, and -9997H, proved to be outside the APE boundaries while the other two, CA-SBR-2282/H and -6847H, no longer retain any of the cultural features or artifacts previously noted in or near the APE, although it is unclear whether any subsurface archaeological deposits may remain at CA-SBR-2282/H. During this study, a previously unrecorded irrigation/drainage ditch was noted across the APE. However, as a minor, ubiquitous, and fragmented element of the historic infrastructure, this feature shows little potential to meet any of the criteria listed above, and does not require further study or a formal evaluation. No other potential "historic properties" or "historical resources" were encountered throughout the course of the study. Based on these findings, the present study concludes that no known "historic properties" or "historical resources' exist within the APE. No further investigations are recommended. Copies of the CRM TECH report "Identification and Evaluation of Historic Properties Victoria Avenue Infrastructure Improvement Project," November 17, 2005 are available at the City of San Bernardino Development Services Department. To reduce the potential for impact to cultural resources to the greatest extent feasible, the following measure shall be implemented. V-1 In the unlikely event cultural resources are encountered during construction, activities in the immediate area of the resource shall be halted and an onsite inspection should be perlormed immediately by a qualified archaeologist. This professional will be able to assess the resource, determine its significance, and make recommendations for appropriate mitigation measures within the guidelines of the California Environmental Quality Act and/or the Federal National Policy Act, if necessary. c. The City's General Plan EIR indicates that the site is not within an area where historical development occurred. No historical resources were identified as occurring within the APE in the survey report by CRM TECH. d. The near surface soils in the project area are primarily derived from floodplain deposits and active alluvial deposits. Such recent alluvium is not considered fossiliferous and the potential for paleontologic resources occurring is considered to be low. Due to the previous disturbance of the alignment by road construction and flood control development, it is considered highly unlikely this project will result in the destruction of a unique ER.o73/1nrtJal Study IS 14 ... r CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY paleontologic resource. No unique geologic features are known or suspected to occur on or beneath the APE of the proJect. To reduce the potential for impact to paleolontologic resources to the greatest extent feasible, the following measure shall be implemented. V-2 In the unlikely event paleontologic resources are encountered during construction, activities in the immediate area of the finds shall be halted and an on site inspection should be performed immediately by a qualified paleontologist. This professional will be able to assess the find, determine its significance, and make recommendations for appropriate mitigation measures. r.-'. e. No available information suggests that human remains may occur on the project site and the potential for such an occurrence is considered low. State and local laws require that local law enforcement agencies (San Bernardino Police Department. Highland Police Department, San Bernardino County Sheriff's Department, County Coroner's Office) will be notified if human remains are encountered. The San Manuel Band of Mission Indians and other designated representatives will be contacted to arrange for management of such remains if relevant. Compliance with these laws is considered adequate mitigation for potential impacts and no further mitigation is required.

The project will require minor amounts of cut and fill to underground utilities and construct sound walls and curb and gutter, etc. No significant cut or fills will result and no mitigation is required. b.. As with much of southern California, the alignment is within a seismically active area and may be subjected to very strong groundshaking during the life of the project. No human occupancy structures are proposed as part of the project, but the sound wall will be between 7 and 10 feet tall along the roadway adjacent to residential development. Due to the nature of the project, the project is not expected to expose people or property to a substantial risk of adverse effects. The City is required to design and construct the facilities to the latest Uniform Building Code (UBC) requirements for Groundshaking Zone 4 and compliance with those requirements is judged to be adequate mitigation associated with seismic groundshaking. No further mitigation is required. c. Data to evaluate the potential for geologic and soils constraints to impact this project was obtained from the City of San Bernardino General Plan, the City of San Bernardino General Plan EIR and the official Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the Harrison Mountain Quadrangle. No portion of the site is located within an Alquist-Priolo Earthquake Fault Zone. No known faults traverse the project alignment. The San Andreas Fault is located less than one half mile north of the northerly extent of the project ER-073/tnrtlat Study IS 16 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY alignment and has a maximum credible earthquake magnitude of 8.5. Implementation of UBe requirements is considered sufficient to reduce potential fault related impacts to a less than significant level. d. The project site is located on Tujunga gravely loamy sand with 0-9% slopes according to the USGS Soil Survey for Western San Bernardino and the USDA Natural Resources Conservation Survey Web Soil Survey. This soil has a high susceptibility to be wind blown erosion according to Table 5.5-1 of the City's General Plan EIR. Figure 5-8 of the General Plan indicates that the site is located within the portion of the City designated as a high wind area. Mitigation measures presented in the Air Quality Section of this document are considered sufficient to reduce potential construction related impacts associated with wind erosion to a less than significant level. In the short term, construction activities have some potential to increase soil erosion from the site. The proposed construction activities may affect more than one acre of land and it may be necessary for the City to file a Notice of Intent (NOI) with the State Water Resources Control Board and secure a National Pollution Discharge Elimination System (NPDES) general stormwater permit for construction activities. Regardless of the need for NPDES permit, the City must implement Best Management Practices to reduce the potential for soil erosion or pollutants leaving the sites and adversely affecting surface water. Therefore, the preparation and compliance with State and local regulations (including the preparation and implementation of a Storm Water Pollution Prevention Plan) is judged to be adequate mitigation for potential impacts to the quality of stormwater runoff. Due to the proposed landscaped or hard-surfaced nature of the road and right-of-way, the potential for substantial long-term soil erosion to occur is considered less than significant. e. Subsidence Subsidence is the shrinking of earth material caused by natural or artificial removal of underlying support. This process occurs in poor, unconsolidated soils and poorly compacted fills. Seismically induced groundshaking, both local and regional, and heavy rainfall are naturally induced causes of subsidence. The substantial lowering of groundwater may also result in subsidence. Figure 5-6 of the City's General Plan and Figure 5.5-3 of the City's General Plan EIR indicate that the project area is not susceptible to subsidence. No groundwater extractions are proposed by this project and affected soils will be properly compacted to current construction standards. Because no impact is forecast to occur, no further mitigation is required. Landslides Figure 5-7 of the City's General Plan and Figure 5.5-2 of the City's General Plan EIR indicate that the project area is not located in a landslide risk area. No potential exists for the project to expose people or property to a significant risk of landslide. No mitigation is required. f. The potential for liquefaction to occur in an area is a function of soil type and depth of groundwater. Soils that are poorly consolidated combined with near surface groundwater during an earthquake lose their shear strength and take on the properties of a heavy liquid.. Liquefaction can result in the loss of foundation support, ground failure due to lateral spreading, and settlement of affected soils. Figure 5-5 of the City's General Plan and Figure 5.5-6 of the. General Plan EIR indicate that the site is not located in an area with moderate or high susceptibility to liquefaction. No habitable or other structures are proposed and no potential for impact associated with liquefaction is forecast to occur with implementation of standard construction design and construction for roadways. g. h. No unique physical features occur on the project site and thus none will be modified by the proposed project. Please refer to discussion under item d of this Section. No mitigation is required.

Other than some petroleum products used during construction, this project will not include the use or storage of explosive or combustible substances. The cleanup of petroleum products during construction, if a release occurs, is regulated by State and local regulations that have been determined to be adequate to reduce the risk of exposure of humans to an acceptable level. As such, it is concluded the potential for this project to result in the reasonably foreseeable ER-073/lmtlill Study IS 18 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY upset or accidental release of hazardous materials, explosion, or create a health hazard is less than significant. No further mitigation other than that required by current regulations is required. b. The project has no potential to create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials because other than some minor amounts of petroleum products used during construction, no hazardous materials will be associated with this project. Compliance with applicable State and local regulations, will reduce potential impacts from accidental releases to the greatest extent feasible. Potential impacts are considered less than significant. c. No schools are located within one quarter mile from the project area of impact according to information in the EPA Enviromapper program, Thomas Guide map and the City's General Plan. The closest schools, Belvedere School and Fairview School, are both between one quarter and one half miles of the project impact area. Please refer to the discussion under items a and b of this section for further documentation. d. Review of available data (site appearance, USGS map, California Department of Toxic Substance Control's (DTSC) Hazardous Waste and Substances Site List (Cortese List), The Leaking Underground Storage Tank Information System (LUSTIS) and the U.S. Environmental Protection Agency (EPA) Enviromapper indicates no past uses in the area of impact that may have involved hazardous materials. The DTSC Cortese List does not include any sites within the project area. The closest sites on the Cortese List are at the former Norton Air Force Base and Newmark Well Fields of the Bunker Hill Groundwater Basin. There is no potential for these hazard issues to impact or be impacted by the proposed project. The EPA Enviromapper does not list any sites within one quarter mile of the project site that are required to report activities (including Superfund, toxic releases, water discharges, air emissions and hazardous waste handlers) to the EPA KMART No. 7609 located at 26655 Highland Ave just over one mile east of the project alignment is listed as a small generator of hazardous wastes. Shell Service Station located at2402 Highland approximately one half mile west of the project alignment is also listed as a small generator of hazardous wastes. No other regulated facilities are located within one half mile of the project area. There is no potential for these hazard issues to impact or be Impacted by the proposed project. LUSTIS does not identify any leaking underground fuel tanks (LUFT) Within one mile of the area of the proposed project. One underground storage tank is located along the project alignment at the intersection of Highland Avenue and Victoria Avenue (Victoria Service, Inc.) per the LUSTIS database. The presence of a regulated underground storage tank will have no impact on the proposed project. No impact is forecast, and no mitigation is required e. Per Figure LU-4 of the General Plan, the project site is not located within an airport influence area. No impact is forecast and no mitigation is required. f. The proposed project is roadway improvements designed to enhance traffic flow and visual appearance while reducing noise levels at adjacent residential properties. Once constructed, this project will be beneficial to emergency and evacuation plans as it will improve traffic flow. In the short term, the construction within the roadway has some potential to interfere with such plans. This issue is evaluated in Item XV of this Initial Study and implementation of Mitigation Measures XV-1 and XV-2 are considered adequate to reduce potential impacts to a less than significant level. g.

No mitigation is required. c-e. The proposed project will result in the concrete lining of a dirt swale located west of the project area along the access road of the Patton Flood Control Basin. The swale conveys stormwater runoff into the flood control basin. Existing storm drain facilities will be modified or relocated including a 24-inch culvert north of PSH at Date Street and an 18-inch culvert located south of the PSH Date Street entry. These facilities will not. substantially alter any drainage pattern or increase surface water runoff. The project will result in roadway expansion that will modify the amount of impervious surface, but as areas that are currently paved will be replaced with landscaping, no significant increase in impervious surface will result from installation of the project. No mitigation is required. The Cities and County have adopted a set of best management practices designed to control discharges of pollution that could cause a significant adverse impact to surface water quality. The document developed by Riverside County, "Supplement A to the Riverside County Drainage Area Management Plans, and Attachment to Supplement A," defines clear best management practices (BMPs) that when applied to this project will ensure that significant erosion, sedimentation, or other water quality degrading impacts (pollution) will not occur from implementing the proposed project. Compliance with State and local regulations regarding stormwater management is sufficient to reduce potential impacts to a less than significant level. f. The proposed project will not substantially degrade water quality during operation or construction with the compliance with State and local regulations regarding stormwater management. No further mitigation is required. g&h. Figure S-1 of the City's General Plan Indicates that the alignment is not within the 1 DO-year flood zone but that it is within the 50D-year flood zone. No housing is proposed by this project. The project has no potential to place housing within a 1 DO-year floodplain or to place structures within an area which could impede or redirect flood flows because no significant drainage courses will be affected. Because no significant alteration of existing drainage patterns will occur, no significant impact will result and no mitigation is required.

The following data was obtained from Noise Impact Analysis Victoria Avenue Widening prepared by Giroux and Associates, January 6, 2006 (Giroux Report). a-c. Noise is defined as any sound that is undesirable or interferes with normal hearing processes. Periods of quiet are necessary for human health and welfare. Although the major adverse impact of exposure to a noisy environment is reduced hearing capacity, the psychological impacts of noise exposure at less than hearing loss thresholds are equally important. There is a variety of noise rating scales used to measure the impact of a noise source. The basic unit of sound pressure is the decibel (dB). Refer to Table'XI-1 a complete definition of this and other noise-related terms. Decibels are a logarithmic scale similar to the Richter Scale for earthquake magnitude. Decibels are a logarithmic ratio of the actual sound level pressure compared to the faintest noise level detectable by a young adult with good auditory acuity. Human ears, however, do not directly convert pressure to loudness. A ten-fold increase in sound pressure thus translates into only a doubling of perceived loudness. By way of perspective, 65 dB is the sound level at which outside noise begins to intrude on the ability to carry on a simple conversation in close proximity between speaker and listener A noise level of 45 dB is typically the level at which sleep disturbance becomes noticeable. ER.Q73ftMlal Study IS 24 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY Table XI-1 DEFINITION OF NOISE-RELATED TERMS Term Definition of Noise-Related Terms Decibel (dB) A unit describing the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micro-pascals (20 micro-newtons per square meter). Frequency (Hz) The number of complete pressure fluctuations per second above and below atmospheric pressure. dBA The sound pressure level in decibels as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise. All sound levels in this report are A-weighted. LlO' L50 and Lga The A-weighted noise levels that are exceeded 10,50, and 90 percent of the time during the measurement period. Equivalent Noise Level (Leq) The steady-state, A-weighted noise level (dBA) that contains the equivalent acoustical energy as all time-varying events during a given arbitrary observation period. The most common averaging period is one hour, written as Leq(1). Community Noise Equivalent The average A-weighted noise level (dBA) during a 24hour day, obtained after Level (CNEL)addition of 5 decibels to levels in the evening from 7 p.m. to 10 p.m. and after addition of 10 decibels to sound levels in the night between 10 p.m. and 7 a.m. Single Event Level (SEL) A descriptor for the A-weighted noise exposure or dose of a transient event. The SEL can be thought to compress the sound energy of a single noise event into an equivalent sound level occurring in a one-second period. Day-Night Noise Level (Ldn) The average A-weighted noise level during a 24-hour day, obtained after addition of 10 decibels to levels measured in the night between 10 p.m. and 7 a.m. Ambient Noise Level The composite of noise from all sources near and far. The normal or existing level of environmental noise at a given location. Because the human ear does not respond equally to sounds of all frequencies, multi-spectral noise is weighted more heavily In frequencies of greatest human sensitivity to gauge true auditory response in a process called A-weighting. A-weighted sound pressure levels are the standard noise representation in California for planning purposes, and are reported as dB(A). Any further reference to decibels in this report written as "dB" should be understood to be A-weighted dB(A). Although the A-weighted noise level may adequately indicate the level of environmental noise at any instant, community noise levels vary continuously. Most environmental noise includes a mixture of noise from distant sources that create a relatively steady background noise in which no particular source is identified. Localized sources are typically superimposed upon the general background. To describe the time-varying character of environmental noise, the statistical noise descriptors. L,o. LSD' and LgD are commonly used. These are A-weighted noise levels that are exceeded during 10, 50, and 90 percent of a stated time period. A single number descriptor called the Leq is also widely used. The Leq is the average A-weighted energy equivalent level during a stated period of time that has the same acoustical energy as the sum of all time-varying events. ER.073/lnltLal Study IS 25 CITY Of SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY In determining the daily level of environmental noise, it is important to account for the difference in response of people to daytime and nighttime noises. During the night, exterior background noises are generally lower than during the day. However, most household noise also decreases at night and exterior noise becomes very noticeable. Further, most people sleep at night and are very sensitive to noise intrusion. To account for human sensitivity to nighttime noise levels, a descriptor, Ldn (day-night average sound level), was developed. The Ldn divides the 24hour day into the daytime of 7:00 a.m. to 10:00 p.m. and the nighttime of 10:00 p.m. to 7:00 a.m. The nighttime noise level is weighted 10 dB higher than the daytime noise level. The community noise equivalent level (CNEL) is another 24hour average that includes both an evening and nighttime weighting. CNEL and Ldn tYPically differ by no more than one decibel. Noise Standards The City of San Bernardino's General Plan Noise Element, at Implementation Measure 114.2, committed to adopt the State of California noise/land use guidelines as shown in Figure 1 in determining acceptability of noise exposures to ambient noise. Measure 114.3 states that the noise standard for new residential uses in the City shall be 45 dB(A) Ldn in habitable interior space, and 65 dB(A) Ldn in usable yard areas. Typical attenuation for residential structures is 20 dB with windows closed to shut out noise (The HUD Noise Guidebook, 1985). Both in order to provide usable outdoor locations where noise is not excessively intrusive, and in order to meet interior standards with no additional measures other than window closure, a noise exposure standard of 65 dBA CNEL is commonly required in most California jurisdictions for any noise-sensitive land uses. Measure 114.7 (b) requires the City to identify and commit to measures to mitigate noise impacts (through insulation, noise walls or buffers, landscaping or other acceptable techniques) for noise-sensitive uses within the 65 dB(A) Ldn noise contour. The Noise Element guidelines and mitigation commitment have been used in the Victoria Avenue widening noise impact and mitigation analysis. The proposed project will only generate short-term construction noise increase. Over the long-term, the project will not generate new noise sources or increase noise levels above that forecast to occur if Victoria Avenue. remains in its present state and this project is not constructed. This results because no new land uses or development is proposed by this project or is projected to occur within the area served by this portion of Victoria Avenue. Virtually no undeveloped land exists within the service area, so no substantial traffic generating uses are forecast to occur. This project is intended to improve the flow of existing and projected future traffic on Victoria Avenue and reduce existing and projected future noise levels at nearby receptors. The project may also include the widening of the southerly side of Highland Avenue between Victoria Avenue and Robinson Road. This widening will allow for the construction of a right-turn lane for eastbound traffic on Highland Avenue onto southbound Victoria Avenue. This turn lane will not alter the volume of traffic on Highland Avenue nor the associated noise levels at adjacent structures. Before this construction can occur, the three residences adjacent to Highland Avenue must be removed thus eliminating these noise receptors immediately adjacent to Highland Avenue. The Giroux Report evaluated the existing noise levels at receptors along Victoria Avenue and the noise levels that are forecast to occur in the year 2030. As previously stated, no substantial new development is forecast to occur in the area served by this portion of Victoria Avenue. Therefore, the primary source of noise in the project area, as is the current condition, will be associated with traffic on Victoria Avenue. Additionally, the projected noise levels will occur whether or not this project is constructed. A primary goal of this proposed project is to reduce noise levels at receptors that are and will be affected by traffic noise generated on Victoria Avenue. ER-073/lnitial Study IS 26 r CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY Baseline Noise Levels A 6 to 7 -foot high wall can attenuate the future build-out noise level to very close to the City standard of 65 dB Ldn without any wall modifications. A noise measurement program was undertaken in March 2005, to verify noise levels along Victoria Avenue. The measured existing noise level at 50 feet from the roadway centerline was determined to be 74 dB Ldn. With projected traffic growth, the future design noise level will be 75 dB Ldn. Perimeter walls generally attenuate noise about one dB per foot of wall height. Therefore, existing 6 to 7 -foot high walls are not adequate to reduce existing and projected future noise levels to 65 dB(A) Ldn in usable outdoor areas and, consequently interior areas. Without additional mitigation, existing walls are inadequate to mitigate the actual traffic noise that exists now and forecast to occur in the future. Standard of SiQnificance A significant noise impact is presumed to occur if usable residential outdoor space will be exposed to noise levels exceeding City of San Bernardino standards of 65 dB CNEL due to project implementation. Increased noise levels will result from an increase in traffic volumes created by traffic growth and by increased traffic capacity on the widened roadway. Because the proposed improvements implement a roadway geometry contained in the City's Circulation Element of the General Plan, the project is considered growth- accommodating, and not growth-inducing. The noise impact issue is therefore whether adequate noise protection exists for existing residential uses for the "with project" configuration. However, it should be noted these traffic volume increases will occur whether or not this project is constructed. The City's interior standard of 45 dB Ldn could also be exceeded if exterior levels exceed 65 dB Ldn, and there is inadequate structural attenuation to achieve the interior standard. The noise attenuation from closed single-paned windows is generally -20 dB. When exterior levels exceed 65 dB, and windows are not upgraded to dual-paned, the interior standard could be difficult to meet. Since perimeter wall mitigation will be designed to achieve a sub-65 dB Ldn exposure at ground level, interior noise issues would relate only to any second-floor exposures not protected by the perimeter wall. Few residences along the proposed improvement corridor are two-story. The primary noise issue will therefore be for usable outdoor space relative to the 65 dB Ldn exterior yard area standard. Noise Impact and MitiQation Analvsis The noise barrier analysis was based upon a design future traffic volume of 28,000 average daily trips (ADT). Because of the logarithmic relationship between traffic volumes and decibels, limited increased traffic volumes will only minimally increase future noise levels. At 28,000 ADT, noise will be an additional 0.5 dB higher than for existing conditions. A future noise level of 75 dB Ldn was predicted at affected residences along Victoria Avenue. A noise reduction of 10 dB is needed from any perimeter barrier. For a receiver located close to a barrier with a fairly narrow set of travel lanes, the noise reduction from a barrier is slightly more than one dB per foot of barrier height. particularly if there is some grade separation between the source and receiver. Wall heights in the 8 to 9-foot high range above the pad elevation will be needed for most affected residences. A lot-by-Iot survey was conducted to establish the pad elevation, roadway elevation, and parcel address. The barrier height at the roadway edge was calculated based upon the noise attenuation goal and specific site geometrics. The required barrier heights as a function of grade separation are as follows: ER-073/lnitial Study IS 27 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY Building Pad vs. Roadway Wall Height above Pad Elev. + 4.0' + 3.0' + 2.0' + 1.0' at grade - 10' - 20' - 30' - 40' 7.0' 7.5 8.0' 8.0' 8.5' 9.0' 9.0' 9.0' 10.0' These computer model results for sound attenuation from a perimeter barrier (FHWA-RD-77-108) were then applied to each affected property with the results shown in Table XI-2. The indicated top-of-wall is at mid-lot along the Victoria Avenue frontage. An even stair-step transition is recommended between the indicated heights, and a small curved wall return is needed on each corner lot to step down to 6 feet above grade as quickly as possible. Table XI-2 shows that two residences have a small second-story section. The noise exposure at the second-story fac;ade is such that single-paned windows are inadequate to reduce levels to the interior standard of 45 dB Ldn. Upgrade of these windows is recommended as part of the noise impact mitigation program if such windows have not already been upgraded.

Conclusion Noise exposures will be reduced to acceptable levels. with modification of the existing perimeter walls to the greater heights shown in Table XI-3, and with the replacement of any second-story windows to dual-paned glass. Therefore, mitigation measures XI-3 and XI-4 shall be implemented to reduce potential long-term noise impacts along Victoria Avenue to less than significant levels. XI-1 The City shall construct noise attenuation walls along Victoria Avenue where needed to reduce exterior noise levels at adjacent receptors to at least 65 dB Ldn. XI-2 The City shall offer to replace existing single-pane second-story windows with dual-pane windows where necessary to reduce interior noise levels to 45 dB(A) Ldn at receptors affected by traffic noise on Victoria Avenue. d. The installation of the proposed road improvements have the potential to generate short-term noise impacts. Generally. these type of construction activities can generate noise levels of about 80 dBA at a distance of 50 feet from the equipment. Noise diminishes at a rate of about 6 dB for each doubling of the distance from the source. This means that construction noise levels at the nearest receptors, residential areas located as close as 50 feet from the construction activities would be about 80 dB(A) on the exterior of those receptors. However, the existing 6-foot walls will reduce construction noise levels to about 74 dB(A) in the rear yards. Such noise levels exceeds the City of San Bernardino's normally acceptable noise standard of 65 dB(A) at the exterior of residential ER-073/lnltlal Study IS 29 ,. CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY development. However these noise standards are for permanent noise levels, while the construction noise level increases associated with this project are short term (about 3 days per occurrence at any given residence along Victoria Avenue), will occur during the less noise-sensitive daylight hours, are not health threatening and are considered less than significant. To mitigate potential impacts to the greatest extent feasible, the following measure shall be implemented: XI-J Construction-related activities may not occur between the hours of 7 p.m. and 7 a.m. No construction vehicles, equipment, or employees ay be delivered to, or arrive at the construction site before 7 a.m. or leave the site after 7 p.m. Construction activities may only occur Monday through Saturday. Due to the type of construction proposed, it is concluded that this project will not expose people to extensive groundborne vibration or groundborne noise levels. No explosives will be used during construction and operation of this project. e&f. The project sites are not within an airport land use plan area nor near a private airstrip. This project does not propose any' type of development that could result in the exposure of people to excessive noise levels associated with airport operations. a.

Discussion: a. The roadway improvements have been designed to accommodate existing, approved and allowed development with an acceptable Level of Service (LOS) on affected roadways as discussed in Section XV, Trans- portationlTraffic. This project will accommodate the development allowed by local land use plans and will not result in impacts to government services that exceed those already reviewed and determined to be acceptable during the environmental review process for the development served by this project. Future development not presently approved will undergo separate environmental review at the time it is proposed. The proposed project is viewed as a benefit to public services in that it will help maintain an acceptable LOS on the affected roadways. An acceptable LOS allows fire, police and other emergency services to achieve acceptable response times. Roadway widening such as is proposed does not generate an increase in demand for public services, but rather better accommodates such services. As previously stated, this project will not induce population growth and therefore, will not place additional demand on parks, schools and other governmental services. Construction and maintenance of the roadway improvements will require the expenditure of funds by the City. Funds for projects such as this are generated from fees and taxes charged by the City. It will be the City's responsibility to set an adequate fee/tax schedule to generate the needed funds to operate and maintain the roadway improvements. No mitigation is required.

This project differs from most projects that involve street improvements in that it does involve any new development or alteration of any existing development. Therefore, this project will not in itself, result in the generation of new traffic. This project is intended to improve the existing transportation system on Victoria Avenue, Highland Avenue, and Lynwood Drive to serve existing and planned for future traffic. The project is also intended to provide a more aesthetically pleasing roadway between Highland Avenue and Lynwood Drive and reduce traffic noise levels at existing receptors along Victoria Avenue. To establish existing traffic volumes, the City had 24-hour traffic counts performed on November 22, 2005 on Victoria Avenue between Highland Avenue and Lynwood Drive. The traffic counts included turning movements at Lynwood Drive, Citrus Street, Mirada Road, and Victoria Avenue. These traffic counts were utilized by the traffic consulting firm of Katz, Okitsu & Associates (KOA) to analyze existing traffic conditions and projected future traffic conditions both with and without the proposed road improvements in the year 2030. The results ER-073/lnitial Study IS 33 .-, CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY of this analysis is provided in a memorandum prepared by KOA dated December 19, 2005 (KOA Memo). Copies of the KOA Memo are available for review at the City's Development Services Department located in City Hall. Data contained in the KOA Memo is provided at this time to analyze potential impacts to the local transportation system that may result from implementing this project. The area northerly of Highland Avenue which is served by Victoria Avenue, Lynwood Drive, Mirada Road, and Citrus Street is essentially saturated by development. Virtually no vacant areas that could be developed are accessed by these roads. Additionally, Victoria Avenue literally "dead ends" at the San Manuel Reservation and Casino (Lynwood Drive). The San Bernardino Mountains and National Forest are located northerly of the Reservation land and no potential for new development and the extension of Victoria Avenue to new traffic generating uses exists. Because Victoria Avenue and the other affected roads exist, as do the traffic generating uses, traffic will continue to occur on affected roadways whether or not the proposed project is constructed. Therefore, the existing roadway configurations and the existing and projected future traffic volumes constitute the existing or baseline conditions. The effects of implementing this project are analyzed by comparing the traffic conditions that are projected to occur with implementation of this project to those forecast to occur if this project is not constructed. Upon evaluation of the existing roads and the potential for development, the City has determined that an annual traffic growth rate of 2 percent would be adequate to forecast future traffic volumes on affected roads. Generally, traffic movement on roads is described in terms of level of service (LOS). The LOS of roadways is subdivided into various designations reflecting the flow of traffic and the degree of congestion. LOS A reflects a condition where traffic moves freely with no delays in travel or traffic movement. LOS A is considered the best operating condition for roadways. LOS F is considered the worst condition with little traffic movement and long delays due to congestion. The City's goal is to maintain at least an LOS C condition on its roadways with LOS D being acceptable under certain conditions. The KOA analysis forecasts the level of service that will result in the year 2030 under both the With and Without project conditions. Utilizing existing traffic data and roadway configurations. KOA determined the existing level of service at the following intersections. LOS Analysis - 2005 Signalized Intersections AM PM Dell Veh Dell Veh VictOria Avenue & Lynwood Drive A/9.8 B 1127 Victoria Avenue & Citrus Street B /121 A /8.0 Victoria Avenue & Mtrada Road B /11.4 A /13.7 To forecast future traffic conditions, KOA made the following assumptions: 1. There will be no growth in traffic volumes on either Citrus Street or Mirada Road because these are discontinuous streets and the development along these streets has been saturated. 2. Traffic on Victoria Avenue will increase at the rate of 2% per year through 2030 including growth due to Casino-related activities and the turning traffic will also increase proportionately. ER.073/lnrt.a' Study IS 34 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY 3. Overall traffic on Lynwood Drive will experience a decline due to elimination of left turn at the intersection with Victoria Avenue where the street terminates. However, it is assumed that the right turn will experience the same 2% growth per the assumption adopted for other arterials. Based on the above, KOA forecast the level of service at the following intersections under both the With and Without project conditions for the year 2030.

A Technical Memorandum was prepared that addressed the traffic impact and its mitigation along Victoria Avenue. However, intersection improvements at Highland and Victoria are also being proposed by the City of San Bernardino. Specific, improvements being considered at this intersection including adding dual left-turn lanes on Highland in the eastbound to northbound direction, and adding a right-turn lane in the eastbound to southbound direction Other improvements include adding a southbound through-lane on Victoria Avenue north of the intersection. These road improvements will not affect the traffic analysis performed on Victoria Avenue rior the findings regarding the level of service at affected intersections as identified in the Technical Memorandum dated December 19m and its associated supplement. Based on the above data, it is forecast that implementation of this project will improve the LOS on affected roadways above that forecast to occur in 2030 without the project. Therefore, no further mitigation for projected traffic impacts beyond implementing this project and Mitigation Measure XV-2 are required. No sharp curves or dangerous intersections are proposed. No increase In roadway hazards will result. ER-<J73l1n,MI Study IS 35 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY In the short term, construction activities have the potential to affect traffic on affected roads by lane closures, detours, etc. To reduce these potential impacts to a less than significant level, Mitigation Measure XV-1 shall be implemented. XV-1 The City shall require that a construction traffic management plan for work in public roads that complies with the Work Area Traffic Control Handbook or other applicable standards to provide adequate traffic control and safety during construction activities. XV-2 The City shall require that all disturbances to public roadways be repaired in a manner that complies with the Standard Specifications for Public Works Construction (green book) or other applicable standards. c. This project has no potential to result in any changes to air traffic. no mitigation is required. e,f &g. This project does not propose any new development which could increase the demand for emergency access or parking capacity. The project is intended to improve the area's transportation system and will not adversely affect any programs or policies supporting alternative transportation.

The roadway improvements have been designed to accommodate existing, approved and allowed development with an acceptable Level of Service (LOS) as discussed in Section XV. Transportationrrraffic. As previously discussed in this document, this project will not contribute to an increase in the population of the area beyond that already allowed or planned for by local land use plans. The only water consumed by the project will be for dust control during construction and for landscaping after installation. No wastewater other than stormwater runoff will be produced by the proposed project. However, the project will not produce runoff substantially beyond that which presently occurs because no substantial increase in hard surfacing will result. No impact can be identified an no mitigation is required. ER-Q73/lnlhal Study IS 37 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY c. No new or expanded storm water drainage facilities beyond minor modification proposed as part of the project are required or associated with this project. Existing storm drain facilities that will be modified or relocated include a 24-inch culvert north of PSH at Date Street, an 18-inch culvert located south of the PSH Date Street entry and the concrete-lining of an existing dirt drainage swale. Compliance with State and local regulations regarding stormwater management is sufficient to mitigate short-term storm water runoff impacts. No further mitigation is required. f. Other than possibly some minor amounts of construction wastes, this project will not generate solid waste. The solid waste system that services the project area has adequate capacity to accommodate construction wastes that could be generated by this project according to the City's General Plan. No conflict with any solid waste regulations will result. Because no impact can be identified, no mitigation is required. XVII. MANDATORY FINDINGS OF SIGNIFICANCE a. Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or- eliminate important examples of the major periods of California history or prehistory? b. Does the project have the potential to achieve short-term, to the disadvantage of long-term environmental goals? c. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively consider- able" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.) d. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?

The proposed project is roadway improvements designed to enhance traffic flow and visual appearance while reducing noise levels at adjacent residential properties. This project will result in impacts primarily within existing road right-of-way with a 16-foot wide expansion of right-of-way of graded land from SBCFCD. The City of San Bernardino area contains state and federally listed plant and animal species. Project impacts will occur within existing developed roads and the adjacent flood control basin property. No portion of the project occurs within federal designated critical habitat. No sensitive species are expected to occur within the project area and no habitat for sensitive species was observed within the project area of impact. ER-073:!Mlal SfuDy IS 38 CITY OF SAN BERNARDINO DEVELOPMENT SERVICES INITIAL STUDY No structures or other examples of major periods of California history or prehistory are located within the project area of affect and, therefore, none will be affected. b. The proposed project will establish an ultimate design configuration that will meet the long-term objectives of the City for Victoria Avenue. Aside from the short-term construction impacts from the proposed project, which are not significant, the proposed project does not result in a trade off of long-term benefits for short-term adverse impacts. c&d. The proposed project is roadway improvements designed to enhance traffic flow to serve existing, entitled or approved development. Such individual transportation projects that are consistent with local planning documents are not considered to have cumulatively significant impacts. Projects that are consistent with current land use planning documents are not considered to have the potential to have impacts that are individually limited but are cumulatively considerable. This document evaluated all CEQA issues contained in the City's latest Initial Study Checklist form. The evaluation determined that either no impact or less than significant impacts would be associated with the issues of: aesthetics, agricultural resources, hazards, hydrology, land use planning, mineral resources, population and housing, public services, recreation, and utilities. No mitigation was proposed and potential impacts are neither individually or cumulatively significant. For the issues of: air quality, cultural resources, geology/soils, noise, and transportation potential impacts were determined to be less than significant both individually and cumulatively with implementation of identified mitigation.

This program has been prepared in compliance with the California Environmental Quality Act (CEQA) and the State and City of San Bernardino CEQA Guidelines. CEQA Section 21081.6 requires adoption of a monitoring and/or reporting program for those measures or conditions imposed on a project to mitigate or avoid adverse effects on the environment. The law states that the monitoring or reporting program shall be designed to ensure compliance during project implementation. The Mitigation MonitoringlReporting Program contains the following elements: I. The mitigation measures are recorded with the action and procedure necessary to ensure compliance. The program lists the mitigation measures contained within the Initial Study. 2. A procedure for compliance and verification has been outlined for each mandatory mitigation action. This procedure designates who will take action, what action will be taken and when, and to whom and when compliance will be reported. 3. The program contains a separate Mitigation Monitoring and Compliance Record for each action. On each of these record sheets, the pertinent actions and dates will be logged, and copies of permits, correspondence or other data relevant will be retained by the City of San Bernardino. 4. The program is designed to be flexible. As monitoring progresses, changes to compliance procedures may be necessary based upon recommendations by those responsible for the program. If changes are made, new monitoring compliance procedures and records will be developed and incorporated into the program. The individual measures and accompanying monitoring/reporting actions follow.

TRANSPORTATION - PATRICK J. MEAD Director of Public Works March 22, 2006 Mr. Mark lancaster, Deputy Director/City Engineer City of San Bernardino, Development Services - Engineering 300 North "0" Street San Bernardino, CA 92418 File #10(ENV)-4.01 RE: NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION FOR THE VICTORIA AVENUE STREET IMPROVEMENT AND BEAUTIFICATION PROJECT Dear Mr. Lancaster: Thank you for giving the San Bernardino County Department of Public Works the opportunity to comment on the above-referenced project. The following comments are from our Water Resources Division concerning this project. The site is located on Victoria Avenue, northerly of Highland Avenue, and is adjacent to the right of way for the Flood Control District's Patton Basin. According to the most recent FEMA Flood Insurance Rate Map, Panel 8763F, dated March 18. 1996, the site lies within Zone X shaded. 1. In general, it appears that the Notice has identified the major concerns of the Flood Control District (District). 2. It is assumed that the City will establish adequate provisions for intercepting and conducting the accumulated drainage around or through the construction site in a manner that will not adversely affect adjacent or downstream properties. 3. We recommend that the project incorporate the most recent FEMA regulations for the protection of utilities. 4. It is noted that the acquisition of District right of way is, or will soon be, in process. 5. It appears that encroachment on District right of way is anticipated. Consequently, a permit shall be obtained from the District's Flood Control Operation Division, Permit Section. Other on-site or off-site improvement may be recommended which cannot be determined at this time. If you should have any questions concerning these comments, please contact Marylou Mermilliod at our Water Resources Division at (909) 387-8213.
