The study was conducted by Michael K. Lerch & Associates at the request of the City Public Works Department, in order to provide information for environmental assessments for the proposed projects. Because the projects will require actions by local, state, and federal agencies, the study provides the necessary information for compliance with the California Environmental Quality Act, section 106 of the National Historic Preservation Act, and the National Environmental Policy Act (NEPA). The field survey of the projects was conducted on Auqust 2-4, 1989, by Michael K. Lerch (see Appendix A), who also authored this report. The five proposed projects are known as: 1) Chestnut Avenue Storm Drain: 2) Palm Avenue Improvements: 3) Palm Avenue/Cable Creek Box Culvert: 4) Palm Avenue/Kendall Drive Traffic Signal: and 5) Bailey Creek Storm Drain. All five projects are located in the Verdemont Planning Area in the northwestern portion of the City of San Bernardino, California. More specifically, they are situated in the extreme southeastern corner of Section 36, T2N, R5W: Section 1 (projected), T1N, R5W: and section 6 (projected), T1N, R4W: SBBM, as shown on the USGS San Bernardino North 7.5' topographic quadrangle, 1967 edition, photorevised 1980 (Fig. 1). The project descriptions are as follows, with numbers and names , corresponding to locations shown in Fiqure 1: 1. Chestnut Avenue Storm Drain. This project will consist of the construction of an underground storm drain from the National Forest boundary to Cable Creek within the 60-toot right-of-way of Chestnut Avenue. A 2-3 acre debris basin will be constructed at the inlet on the northern end of the drain. The approximate length of the storm drain will be 5,000 feet. For purposes of this study the area of potential environmental impact was considered to be 100 feet (30 meters) wide and one mile long. 2. Palm Avenue ImDrovements. This project involves widening of Palm Avenue to its full right-of-way width, which varies from 88 to 100 feet, from the boundary of Muscubiabe Rancho on the north to Kendall Drive on the south, a distance of one mile. CUrbs, qutters, sidewalks, and street lights will be constucted in those portion of Palm Avenue where they are currently lacking. Full right-of-way improvements have already been made adjacent to some recent developments, which amount to approximately 10\ of the total length of the project. For purposes of this study the area of potential environmental impact was considered to be 150 feet (45 meters) wide and one mile long. 1 REFERENCES Jeffrey H., Martin R. Rose, and Michael K.

The study addresses historic structures older than 45 years, historic archaeological resources older than 100 years and all prehistoric archaeological resources. Signifi- cance' was to be determined with reference to criteria for eligibility for listing in the National Register of Historic Places (36 CFR 60.4). These criteria may also be used for determining whether a resources is "important" as defined in CEQA Appendix K. METHODS OP DATA COLLECTION Prior to the fieldwork portion of the study, an records check for previously recorded sites and was conducted at the San Bernardino county Information Center, located at the San Bernardino Redlands (see Appendix B). Available archaeological, ethnographic, and historical literature was reviewed in order that known or expected site types for the region could be anticipated and accurately identified during the field survey. other sources consulted included the National Reaister of Historic Places (USDr 1979), California Inventorv of Historic Resources (DPR 1976), and California Historical Landmarks (DPR 1982). archaeological surveyed areas ArChaeological County Museum, Archival records reviewed included the US Government Land Office plat map of Rancho Muscupiabe, surveyed by Henry Hancock in 1867, the USGS San Bernardino 1901 15' quadrangle (based on surveys conducted in 1893-1894), and the US Army Corps of Engineers San Bernardino 1942 15' quadrangle (based on surveys conducted in 1940-1941), on file at the San Bernardino County Archaeological Information Center, San Bernardino County Museum, Redlands. In addition to the above historic maps, various other local history sources pertinent to the area which were provided by the Information Center also were reviewed. An intensive cultural resources inventory potential environmental impact for all conducted by the author on August 3-4, 1989. are described as follows, for each project: 1) A transect spaced approximately 30 feet (10 meters) was walked on each side of the current road alignment for the entire length of the project and parallel transects spaced approximately 10 meters apart were walked in a northwest/ southeast direction over an area of approximately 5 acres where the debris basin is proposed: of the areas five proj ects Field methods of was used 4 Archival Research The principal reason for reviewing the various historic maps of the project area was to determine whether any historic structures or historic archaeological resources might be present on or adjacent: to the project route. None of the historic maps researched depicted any structures or other cultural features in or immediately adjacent to the project areas of disturbance, although a number of potential historic resources are depicted in the qeneral vicinity of the projects. RESULTS OP THE STUDY The results review, and prehistoric immediately impact. Although no surface evidence was observed, buried prehistoric ~ archaeological resources are considered a possibility in the ) upper portions of the Bailey Creek storm Drain project. Altschul, Rose, and Lerch (1984:12) noted that the present qround surfaces in much of San Bernardino Valley are dynamic features, and that archaeological sites of any antiquity along the tributaries of the Santa Ana River are pJi'obably buried. The potential for buried archaeoloqical resources to be encountered in the upper Bailey Creek area is considered moderate due to the~ environemtnal context at the mouth of a canyon and the proximity of a source of natural fresh water. of the records checks, literature and archival field survey of the project sites were neqative. No or historic cultural resources were observed in or adjacent to any of the project areas of potential POTENTIAL PROJECT IMPACTS Due to the negative results of the study as noted above, no adverse impacts to known cultural resources eligible or potentially eligible for listinq in the National Reqister of Historic Places are anticipated from construction of the five public works infrastructure improvements in the Verdemont Planninq Area, Assessment District U87. In the event that subsurface cultural deposits with no surface evidence are present in the Bailey Creek area, they could be subj ect to adverse impacts. Any buried cultural resources located within the proposed riqht-of-way would be impacted. RECOMMENDED MITIGATION MEASURES No further preconstruct ion archaeological investigation is warranted for the five infrastructure projects. However, it is recommended that an archaeological monitor should be present~ xi durinq construction excavation of the Bailey Creek Storm Drain,l~ so that in the event subsurface cultural materials are encountered, such materials can be evaluated and appropriate data 7 recovery/protection measures implemented it necessary. It this recommended measure is implemented, it can be concluded that none ot the proposed projects will have an adverse ettect on "important- cultural resources as detined by CEQA Appendix K, or on properties eliqible or potentially eliqible tor listinq in the National Reqister ot Historic Places, as detined in 36 CPR 60.4. 8 REFERENCES Jettrey H., Martin R.

DISCUSSION OF ENVIRONMENTAL EVALUATION AND MITIGATION MEASURES 1.e., 2.a., and 5.a. Construction could result in transient impacts on the physical environment (erosion, drainage, etc.) as well on the community (dust, noise, etc.). Drainage and erosion viII be controlled with the use of sandbags during construction. Soil will be watered to minimize dust and wind erosion. compliance with San Bernardino Municipal Code Section 8.54 will minimize potential impacts resulting from the temporary increases in noise. Resultant construction impacts concerning erosion, drainage, dust, and noise will be reduced to a level of insignificance. lof. The project will result in the modification of Cable Creek at Palm Avenue with the construction of the box culvert on the creek. The box culvert is being constructed to support the widening of Palm Avenue and to enable all weather access on , Palm Avenue across Cable Creek. The box culvert will not restrict or reroute flows in or along Cable Creek. Approval for the culvert must be obtained from the San Bernardino County Flood Control District. Impacts resulting from the construction of the Cable Creek box culvert will be insignificant. 2.c. The project is located within a high wind hazard area. Soil will be watered to minimize wind erosion of soil during construction. Given the nature of the project, high wind will result in no significant impacts. 3.a., and 3.b. The project lies within a 500 year flood zone and the project will result in a change in the drainage patterns in the area. There will be no significant impacts since the project will improve drainage in the area and reduce the potential for flooding. 4a., and 4.b. The project lies within a Biological Management Overlay District. A biological impact assessment was conducted by Lawrence F. LaPre, PhD. of Tierra Madre Consultants, Inc. (attachment "A".) The assessment indicates the absence of biological resources in Project Number Public Works Project No. 90-08 February 12, 1990 C. DISCUSSION OF ENVIRONMENTAL EVALUATION AND MITIGATION MEASURES (continued) 4.b. (continued) the right-of-way for the street improvements along Palm Avenue, at the Palm Avenue crossing of Cable Creek (the site of the box culvert), and at the intersection of Palm Avenue and Kendall Drive. However, the study indicates the probable loss of less than five native trees, California Walnuts and California Sycamores, due to the Palm Avenue improvements. To mitigate o these re , cement of the same species of tree shall be planted along the street in the same vicinit as those 10 6.c. The project is located within Greenbelt Zone "C" and in a moderate fire hazard area. Due to the nature of the project potential impacts will be insignificant. 9.d. There could be temporary alterations of present traffic circulation on Chestnut Avenue south of Irvington Avenue during construction of the storm drain. During the excavation phase, portions of the street may have to be torn up. Traffic control such as barricades, flagmen and detours satisfactory to the City Traffic Engineer and required by San Bernardino Municipal Code 12.04 shall be maintained throughout project construction. Impacts will be reduced to a level of insignificance. 13.a. The project lies within an area of archaeological concern. Michael K. Lerch and Associates were enjoined to conduct an archaeological survey and study of the site (Attachment "B".) From the study and survey it was concluded that no adverse impacts to known cultural resources were expected from the construction of the Palm Avenue street improvements, the box culvert on Cable Creek, or the traffic signal at the intersection of Palm Avenue and Kendall Drive. However, during construction of these projects, should any archaeological resources be uncovered, all grading and/or construction shall halt and a qualified archeologist shall be consulted to document, remove, and otherwise preserve any archaeological resources located at the site. Anlrc\\I\!.W\ A' Verdemont Infrastructure: Phase 1 Biological Assessment Tierra Madre Consultants, Inc. Lawrence F. LaPre, PhD Robin Bishop November, 1989 Introduction This report was contracted by Michael K. Lerch & Associates to provide the city of San Bernardino Public Works Department with site-specific information on five infrastructure projects in the Verdemont area. The location of these projects is given in Figure 1 and they are described briefly below: 1. Chestnut Avenue Drain underground storm drain undeveloped Chestnut Avenue base of the foothills. constructed at the inlet. This consists of construction of an within the 60' right-of-way of from the Cable Creek crossing to the A 2-3 acre debris basin will be 2. Palm Avenue Imorovements. Palm Avenue will be improved with curbs, gutters, sidewalks, and streetlights within the existing right-of-way (88-100'). Improvements are planned for all unfinished segments of Palm Avenue from Kendall Drive to the Muscubiabe Rancho line. 3. fslm Avenue Box Culvert. A box culvert will be constructed at the crossing of Cable Creek by Palm Avenue. 4. Palm Avenue/Kendall Drive Traffic Sianal. will be installed at the intersection of Palm Drive. A traffic signal Avenue and Kendall 5. Bailev Creek Storm Drain. This proj ect is to construct a concrete trapezoidal channel from the existing channel near the corner of Walnut Avenue and Belmont Avenue along the existing stream channel to the mouth of Bailey Canyon, where a debris basin will be located. The Chestnut Avenue drain, the Bailey Creek drain, and the Palm Avenue box culvert will require permits from the California Department of Fish and Game and the U. S. Army Corps of Engineers. These agencies guide development within stream beds, and often require mitigation for adverse impacts to riparian vegetation that is found along stream channels. This report is intended to provide baseline data on the biological resources of these project areas, particularly existing riparian vegetation and habitat values. Suggestions are also provided so that the City can prepare applications for the wetland permits and plan for the expected mitigation that could be imposed as permit conditions. PW ~-07 Methods A literature review was conducted to identify any sensitive elements which are known to occur on or in the vicinity of the property. This included consultation with the California Natural Diversity Data Base (Data Base). We also reviewed the earlier report of Pacific Southwest Biological Services (1985) on the Verdemont planning area, as well as pertinent environmental documents from other development projects in the area. Information included in the San Bernardino National Forest Land and Resource Management Plan (1988) for the Bailey Canyon area was reviewed as well. Following the literature review, a field survey was performed by Robin Bishop on May 9, 11, 12, 18, and 19, 1989. L. LaPre reviewed all of the project sites on. August 20, 1989. Twenty hours were spent walking over the sites and all plant and animal species detected were recorded in field notes. Common names are used in the text for all species. Appended to this report is a species inventory for each project site except the signalization (Project #4) which provides both scientific and common names. The signalization project area was entirely paved, and contained no plants or animals. Results The Verdemont area is characterized by alluvial deposits which are dissected streambeds draining the adjoining chaparral- covered slopes of the San Bernardino National Forest. The vegetation on the alluvial fans and terraces is in a transition between the coastal sage scrub communities of lower elevations and the chaparral of the higher elevations and steep sloes. The vegetation reflects the long-term activities of the Cajon Creek drainage, supporting both elements of the alluvial sage scrub community and a rather large stand of California walnut trees. These noteworthy California native plants reach the eastern edge of their distribution in the Cajon Pass. The walnut woodland is a declining native plant community (Holland 1986). The walnut treespresent in the Verdemont area are not in a woodland formation, but rather are found as large isolated trees on the alluvial bench and as trees and shrubs within the riparian drainages. The Riversidian alluvial fan sage scrub plant community is a species-rich assemblage of shrubs typical of both the coastal sage scrub and chaparral communities, though coastal sage species are generally dominant (Sanders, 1987, citing Smith). This vegetation formerly covered most of the alluvial slopes in the Los Angeles basin, but has now been greatly reduced in extent by urban expansion (Smith, 1980, citing Hanes). This is the same fate that has befallen the more typical coastal sage scrub of adjacent foothill slopes and plains: it has been estimated that 2 this community has been reduced in extent by 90t due to urbanization (Sanders, 1987). Most authors have included alluvial SCruD within their concept of coastal sage scrub and even smith agrees that alluvial SCruD is part of the coastal sage scrub "type" (Sanders, 1987). Holland, (1986) includes the community in his inventory of natural communities in California. Because this vegetation association is thought to be in decline, it is designated by the Data Base as a community with highest inventory priorities. Riparian communities occur along drainages and provide plants adapted to temporary or permanent water with the conditions to survive. Riparian vegetation provides high-quality wildlife habitat. Because of the extensive loss of riparian communities in california, the protection of this vegetation is a top priority of the California Department of Fish and Game CDFG). The California Fish and Game Commission has adopted a policy of "no net loss" of wetlands for the state, which includes riparian wetlands. The riparian communities bordering the streams within the Verdemont area are narrow bands of dense trees and undergrowth. Most of the drainages support a diverse plant community which is high-quality wildlife habitat. The historic vegetation in the Verdemont area has been modified into what is now a degraded community of coastal sage scrub vegetation with scattered walnut trees on .the uplands, and remnant strips of good riparian communities along the drainages. The Riversidean alluvial fan sage scrub is only present as a distinct association west of Interstate 15, and none of the rare species known to occur in this community are found near the Phase I infrastructure project area. The walnut woodland, if ever present, has likewise been reduced to scattered older trees, some of which are found within the infrastructure project boundaries. Only the riparian communities appear to have maintained their historic structure and species diversity. The biological resources of the individual infrastructure project sites are discussed separately below. Chestnut Avenue Drain Chestnut Avenue is undeveloped along most of its length north of Belmont Avenue. The road right-of-way follows dense rows of EucalvDtus and olive trees, and contains a wide ditch in the centerline. The streamcourse parallels Chestnut Avenue, and does not appear to be part of the sixty foot right-of-way. A large number of riparian trees, mainly sycamore, elderberry, and willow are found in the stream channel that borders the Chestnut Avenue right-of-way. A dense understory in most places is made up of mulefat, poison oak, squawbush, tarragon, and western ragweed. This riparian vegetation is of high importance as wildlife habitat, contrasting with the 3 artificial ditch and bordering ornamental trees within the road right-ot-way. The debris basin site contains primarily a disturbed coastal sage scrub plant community, dominated by buckWheat and coastal sagebrush. The stream channel at this location includes a scrub vegetation ot mulefat, with about eight smaller sycamore trees. The dry riparian debris basin site is much less well developed than the riparian woodland located downstream. fAlm Avenue Imorovements No significant biological resources exist within the right- of-way tor the planned improvements to Palm Avenue. We estimate that the improvements will result in the removal of one sycamore, one California walnut, several Eucalvotus, and a few olive trees. ~ Avenue ~ Culvert No significant biological resources are found at the Palm Avenue crossing of Cable Creek, where the box culvert is planned. Cable Creek is channelized and riprapped at this location, and virtually no vegetation exists in the stream channel. Along the borders for 200" in either direction, the plants consist of weedy natives such as Jimson weed and doveweed, along with many undesirable introduced European grasses and weeds. Palm Avenue/Kendall Drive Traffic Sianal The intersection to be signalized is completely disturbed or paved and contains no biological resources. Sailev Creek Storm Drain Bailey Creek, where it crosses over the alluvial plain downstream to Walnut Avenue near Belmont Avenue supports a lush and very significant riparian community. At the debris basin site, most trees are in excess of forty feet in height. Wildlife is abundant in and near this stream channel. In addition to sycamores, mulefat, willows, and elderberry, we observed one fifty-foot-tall incense cedar, and four bigcone Douglas fir, all of which appeared to be naturally-occurring "washdown" plants from higher elevations. The riparian community is somewhat invaded by tall Eucal votus, but continues as a strip of dense trees downstream almost the entire way to the junction with the existing concrete trapezoidal channel. Just upstream from the channel is the driest and least significant portion of this creek. Sensitive soecies The computerized search of the Data Base, previous reports from the area, and other materials listed in the references section of this report indicated that four sensitive plants, two sensitive animals, and one natural community have been recorded 4 in the vicinity of the Verdemont infrastructure projects. Two other plants, the thread-leaved brodiaea and the San Bernardino owl's clover, were also reported from the San Bernardino North quad, but these plants are montane species found at higher elevations and have no sui table habitat near Verdemont. Therefore, they were eliminated from further consideration. Sensitive species are so-called because their populations are declininq, they are especially vulnerable to habitat change, or because they have restricted distributions and are therefore uncommon. For a summary of those sensitive species potentially occurrinq in the Verdemont infrastructure project area, see Table 1. 5 Table 1. Sensitive species considered for the infrastructure projects.

See references. for federal and state designations. occur 7 The potentially-occurring species listed in Table 1 are discussed below and the results ot the field surveys to determine their presence or absence are given. Slender-borDed spine flower is a small, low-to-the-ground, spring-blooming annual of the buckwheat family. Its preferred habitat is dry sandy benches of washes below 2,000 teet in the coastal sage scrub or alluvial sage scrub plant communities. Although populations of the slender-horned spineflower range from the San Fernando Valley to the San Bernardino Valley and the Elsinore area, most historic locations have been eliminated by urbanization and river modification for flood control. This extensive loss of habitat has resulted in the. listing ot this species as endangered by the State of California and the U. S. Fish & Wildlife Service. The Data Base reported a population of slender-horned spineflower in Cajon Canyon near Devore, somewhat west of the project sites. No suitable habitat for the slender-horned spine flower exists on the Phase I Verdemont infrastructure sites. All known habitat and occurrences are west of Interstate 15. The Santa Ana River woolly-star is a small gray-green shrub of the phlox family with blue flowers. It occurs in alluvial fan sage scrub of the higher flood plain terraces of the Santa Ana River and its tributaries and tends to occupy habitats with little evidence of surface disturbance. The historic range of the Santa Ana River woolly-star spanned approximately sixty river miles from Rancho Santa Ana in Orange County at an elevation of SOO ft. to the the vicinity of Highland in San Bernardino County at 1500 ft. It is currently restricted to several disjunct populations on Lytle Creek and in the flood plain of the Santa Ana River from Redlands to the mouth of the Santa Ana Canyon in San Bernardino County. The total range has been reduced by at least 70% to about 18 river miles. Human encroachment through intensive use of the flood plain margins for urbanization, flood control structures, ground water recharge facilities, sand and gravel mining, and farming has further reduced the suitable habitat for the plant by greater than 90%. This extensive loss of habitat has resulted in the recent listing of this species as endangered by the State of California and the U. S. Fish & Wildlife Service. The Data Base reported an extirpated location of the Santa Ana River woolly-star in the vicinity of Devore. Krantz (1987) reported 16 small woolly-star plants 0.3 mile north of Institution Road on the west side of Cajon Boulevard. The woolly-stars at the Sheriff's Training Center site have been studied (Tierra Madre Consultants, 1988) and determined to contain intergrade pOpulations, representing genetic crossing between two subspecies. 8 All known sites for the Santa Ana River woolly-star are west ot the infrastructure proj ects in Verdemont. No sui table alluvial sage scrub habitat is present on the project sites, and no woolly-star plants were seen. The range ot the SaD Diego horDe4 lizar4 extends from near the coastline eastward through the interior valleys and plains to the slopes ot the San Bernardino, San Jacinto, and Santa Rosa Mountains. This species is also known from western San Diego County but is absent from southern California deserts. Preferred habitat consists primarily of flatlands occupied by grassland, coastal sage scrub, sparse chaparral, and occasionally, upper elevations ot open, coniferous woodlands. It is rarely found under closed-canopy, evergreen cover. open stretches ot sandy soil used for basking, cover, and social behavior, are apparently a critical habitat component. Ants are the primary food of this species although, it will also feed on other insects. Populations of this lizard are declining due to extensive collecting on wildlands and as a result of its habitat being converted to agricultural and urban uses. This lizard has been recently reported from Cajon wash, and is expected to occur in the less-disturbed lands of the Verdemont planning area. This includes the Chestnut Avenue drain and the Bailey Canyon strom drain project areas. Very little is known about the Los ADqeles pocket mouse. It apparently digs underground burrows and is nocturnal, and is ~herefore not often detected except in trapping surveys. The geographic range is restricted to lower elevations in grassy areas from Burbank to San Bernardino and eastwards to Aguanga in Riverside County. Urbanization and cul ti vat ion have eliminated much of the habitat for this uncommon rodent. In 1931 there was a report of the Los Angeles pocket mouse from 4.75 miles north of San Bernardino. The records presented by Williams (1986) indicate that this species ranged mainly in the San Bernardino Valley. Therefore, it is not known whether or not the Verdemont area would provide suitable habitat, since it appears to lie at the upper elevational edge of the species range. In addition, the probable habitat of this species is grassland or coastal sage scrub, rather than the riparian vegetation found at the least disturbed infrastructure project sites. The most likely locations for this species, if it occurs, are at the edge of the drainages on the Chestnut Avenue and Bailey Canyon drain projects. A focused trapping study would be required to absolutely determine the presence or absence of the Los Angeles pocket mouse. Because of the nearness of the historic record and the fact that some sage scrub habitat is found at the edges of the Bailey Creek and Chestnut Avenue drainages, we believe that a moderate probability exists for occurrence of this rodent. 9 In SU1lll'1ary, no rare, threatened, . or endanqered species of plant or animal was found on any ot the intrastructure project sites. Potential habitat is available at the c~estnut ~treet\ drain and Bailey Dreek drain sites for two declin1ng spec1es of wildlite which are candidate species tor future federal , . protection under the Endanqered Spec1es Act. Discussioll One of the proposed infrastructure projects did not contain any native vegetation or wildlife habitat, or any other siqnificant bioloqical features. This project, the signalization of the Palm Avenue/Kendall Drive intersection, is excluded from further discussion of bioloqical resources. The Palm Avenue box culvert lacks biological significance except as a component of the Cable Creek. stream system, which contains hiqher resource value upstream and downstream. The Palm Avenue widening improvements affect biological resources only minimally, resulting in the loss of a few native trees. However, the\, Chestnut Avenue drain project contains significant riparian J vegetation. Three of the five Phase 1 infrastructure projects will require permits from the Department of Fish and Game under Sections 1601-3 of the Fish and Game Code. These same projects will also probably require permits from the Corps of Engineers, which administers Section 404 of the federal -Clean Water Act. Because the Palm Avenue box culvert will not impact .riparian habitat of any important biological resources, the permitting for t,his project will be ministerial after submittal of the application with fee. The Chestnut Avenue drain and the Bailey Creek storm drain, on the other hand, will require permits from the CDFG and the corps of Engineers. The permitting requirements and further analysis that might be needed for each of the proj ects is discussed below, along with recommendations and potential mitigating measures for loss of biological resources. Chestnut Avenue Drain Most of this project appears to lie outside of the blueline stream channel depicted on the USGS map. Therefore, permitting by the Department of Fish and Game and Corps of Engineers may not be necessary. Less than one acre of existing riparian vegetation will be impacted by construction of a 2-3 acre debris basin at the base of the foothills. However, the debris basin may prevent \ water from reaching the existing native trees in the former stream channel. If the debris basin cuts off the flow to the existing natural stream channel, a Streambed Alteration Agreement with the Department of Fish and Game will be required. Although the impact of this diversion is unknown, we would expect a gradual die-off of the native trees, even without surrounding . development. 10 We recommend that the line of native sycamores, walnuts, andl willows be retained to the extent possible within any future planned development adjacent to Chestnut street. The riparian woodland could form a greenbelt of some sort adjacent to Chestnut street. Higher-density development of the non-riparian lands wi th retention of the riparian strip would be preferable to removal of the trees. Construction of the Chestnut Avenue drain will result in the removal of several hundred mature Eucalvotus and olive trees, alonq with about twenty California sycamores and perhaps one or two california walnuts. These trees should be replaced with plantings of street trees once the Chestnut Avenue improvements are in place. We recommend the use of California sycamore, California walnut, Fremont cottonwoods, white alders, and other native trees for replacement plantinqs, rather than olives, Eucalvotus, or other ornamentals. The older neiqhborhoods of Verdemont have been planted with California sycamores, and the result is a shady street that still provides some wildlife with valuable habitat. ~ Avenue Imorovements This project has no substantial biological resources, and no mitigation of adverse impacts is required. The project is outside of the jurisdiction of the Department of Fish and Game and the Corps of Engineers. The loss of less than five native trees (California walnut and California sycamore) could be mitigated with the replanting of these same species as street ~rees lining the sidewalk. ~ Avenue ~ Culvert No important biological resources would be impacted by this project, so mitigating conditions are not expected to be necessary. Because the size of the stream channel that is being altered is so small, the 1601 and 404 permits required by the Department of Fish and Game and the Corps of Engineers will be mainly a matter of notification to the agencies. ~ Avenue/Kendall Drive Traffic Sianal This project has no biological resources, and no mitigation of adverse impacts is required. The project is outside of the jurisdiction of the Department of Fish and Game and the Corps of Engineers. Bailev Creek storm Drain Construction of the Bailey Creek storm drain will present very significant impacts to the biotic environment. We do not believe that the Department of Fish and Game or the Corps of Enqineers will issue a permit for the project as proposed. Heavy mitiqation in the form of riparian enhancement in other areas is sure to be a condition of approval, if approval can be obtained. 11 We rec~mmend that the city rethink the Bailey Creek drainage plan. The best location for a debris basin from t~e biological perspective would be at the inlet ?f the exi~tln~ conc~ete channel. Even here, impacts to the Balley Creek rlparlan ~abltat would be substantial. At all other locations upstream, lmpacts to the riparian vegetation would be highly significant. We cannot recommend in favor of proceeding with the Bailey Creek storm drain project as proposed. The conversion of the former creek where the concrete channel is now is a classic example of what the Fish and Game Commission is attempting to prevent with its new "no net loss of wetlands" policy. A better plan would preserve the remaining drainage course as a natural greenbelt. This may require reducing the density approved for the surrounding lands so that the developed. lots will not be subj ect to flooding. Perhaps a levee could be constructed outside of the riparian zone on either side to protect lands from flooding. Land uses that are compatible with the retention of the riparian strip, such as a golf course or parks, should be considered. - Alternative designs and locations for a debris basin might reduce the biological impact. The further downstream the debris basin is placed, the lower will be the biological impacts. At and within the Forest Service boundary, the riparian vegetation is especially dense and diverse. The Forest Service is unlikely to approve a drainage plan that disturbs this habitat on their lands, so we recommend that the debris basin be placed downstream. Additional study will be necessary to proceed with the permits required by the Department of Fish and Game and the Corps of Engineers. We anticipate that the Corps will insist on a discussion of alternatives, and that they might require a federal Environmental Impact Statement to be prepared on the issuance of a permit. If the application is accepted as now envisioned, extensive mitigation will likely be required. In similar cases in the past, permit conditions have included provision of replacement riparian acreage. Enhancement of a degraded stream channel at another location with riparian species could mitigate the loss of the existing habitat. Enhancement projects have often been required at a replacement ratio of 1: 1, meaning for every acre of riparian habitat lost, one acre must be enhanced or restored. Purchase of an existing riparian habitat for purposes of protection is also a mitigation possibility. In cases like this, purchase of habitat has been accomplished at a ratio of 3:1 or greater, even of up to 10:1 on an acre-for-acre basis, depending on the value of the riparian habitat being lost. 12 Reference.

A\t"PcCI,\ Io\ft.tJ'r e, CULTURAL RESOURCES ASSESSMENT OF FIVE PUBLIC WORKS INFRASTRUCTURE IHP~OVEMENTS, VERDEMONT AREA ASSESSMENT DISTRICT 1987, CITY OF SAN BERNARDINO, CALIFORNIA Prepared by: MICHAEL K. LERCH , ASSOCIATES Michael K. Lerch, Project Archaeologist Post Office Box 55134 Riverside, CA 92517-0134 Prepared for: CITY OF SAN BERNARDINO Public Works/Engineering Department 300 North "0" street San Bernardino, CA 92418 Purchase Order No. 904104 MKLA-902 November 1989 fJw tp"'07 MANAGEMENT SUMMARY In August 1989, an archaeol,ogical survey of five public. works infrastructure improvements ln the Verdemont area of the Clty of San Bernardino was conducted by Michael K. Lerch & Associates at the request of the City Public Works Department, in order to provide information for environmental assessments for the proposed projects. Because the projects will require actions by local, state, and federal agencies, the study provides the necessary information for compliance with the California Environmental Quality Act, section 106 of the National Historic Preservation Act, and the National Environmental Policy Act (NEPA) . The archaeological survey was preceded by a records check with the Archaeological Information Center, San Bernardino County Museum, and a review of relevant literature and archival sources. The five proposed projects are known as: 1) Chestnut Avenue storm Drain; 2) Palm Avenue Improvements; 3) Palm Avenue/Cable Creek Box Culvert; 4) Palm Avenue/Kendall Drive Traffic Signal; and 5) Bailey Creek storm Drain. All five projects are located in the Verdemont Planning Area in the northwestern portion of the City of San Bernardino, California. The results of the records check, archival and literature review, and archaeological survey were negative. No impacts to historic or prehistoric cultural resources eligible or potentially eligible for listing in the National Register of Historic Places , are anticipated from construction of any of the five Verdemont infrastructure improvements, and no further cultural resources investigations are recommended. However, because of the possibility of encountering buried cultural deposits during excavation for the Bailey Creek Storm Drain, it is recommended that an archaeological monitor be present during initial excavation for that project in order that any such materials encountered can be evaluated and appropriate data recovery/ protection measures implemented if necessary. i APPENDIX A PERSONNEL QUALIFICATIONS 10 PERSONNEL QUAL:r:nCATIONS The principal investigator, field archaeologist, and report author for this study was Michael K.

A field survey for prehistoric archaeolooical re.ources, historic archaeolocical resources and historic structures is .troncly recommended. 2. An envIronmental impact review is recommended to establish the sionificance and intecrity of known cultural resources and/or resources identified from a field survey, and to prOPose appropriate mitloat'on measures. 3. A cultural resource manacement report must be prepared to document the inventory, evaluation and mitioation of resources within this prOiect area. If mechanical testing or ewcavation is undertaken, contact Underground Service Alert at (BOO) 422-4133 for information regarding buried utilities. ThIS service is provided free of charge. .If prehistoric or historic artifacts over 50 years in age are encountered during land modification. then activities in the immediate area of the finds should be halted and an on-site inspection should be performed immediately by a qualified archaeologist. This professional will be able to assess the find, determine its significance, and make recommendations for appropriate mitigatIon measures within the guidelines of the California Environmental Quality Act and/or the Federal National Environmental Policy Act. 3 If humAn remAins Are encountered on Any property within SAn BernArdino County. then the SAn Bernardino County Coroner's office must be contActed within 24 hours of the find. and All work should be hAlted until A cleArAnce is given by thAt office And Any other involved agencies.
