RECOMMENDATION That the City Council a) approve the attached Final Tract Map No. 52267; b) authorize the Mayor to execute the Subdivision Agreement; c) adopt Resolution No. 2000-xx; d) authorize the Deputy Director of Public Works to sign the map; e) direct the City Clerk to certify and process the map and C.C. & R's for recordation, and f) direct the City Manager to sign the Escrow Instructions and Entry Permit. FINANCIAL SUMMARY Approval of the map has no impact on the City's budget. BACKGROUNDIDISCUSSI ON The Tentative Map application was made to the Planning Commission at a duly noticed public hearing on May 12, 1998 which the Commission concluded its review of the application and adopted Resolution Nos. 98-11 and 98-12 recommending City Council approval of the applicants proposed project. The City Council conducted duly noticed public hearings on this application on July 7, 1998 and August 18, 1998. On October 6, 1998 City Council meeting, Council adopted Resolution Nos. 98-59 and 98-60 approving Vesting Tentative Tract Map No. 52267, The conditions of approval require that certain improvements be constructed for this development. As the improvements have not been completed at this time, the Subdivider is prepared to enter into an agreement with the City to construct these improvements as a condition precedent to approval of the final map and has offered surety bonds to secure his performance. The subdivision agreement provides for the construction of all improvements and setting of subdivision monuments within 2 years. Also, Labor and Material and Performance Bonds have been posted for Grading, Street, Storm Drain, Sewer, Domestic and Reclaimed Water, Off -Site, Monument and Landscape/Irrigation Improvements. The Final Tract Map subdivides 65 acres of the 339.3 acre site into 127 single family units, removes map restrictions on portions of Lots 5 and 7 of the underlying Tract 31479, and dedicates the balance of Lots 4,5, and 7 of the underlying Tract 31479 (264.3 acres) and all of Lot 9 of the underlying Tract 31479 and Lots 50 and 51 of Tract 42576 (86.0 acres) to the City as open space. The remainder of Lot 4 of underlying Tract 31479 (10 acres adjacent to Summit Ridge Park) is proposed to be dedicated to the City as public park land. Dedication of these Open Space areas are to be made to the City through a Grant Deed which is currently being reviewed. Title will transfer to the City with map recordation. The subdivider has prepared escrow instructions to deliver to the City funds in the amount of $1,409,787.05 to satisfy conditions of the tentative map. An Entry Permit has been requested in order to permit the developer to enter upon the City open space property for the purpose of satisfying map conditions during the term of construction. The subdivider has requested minor technical changes to the approved tentative tract map. SunCal / Diamond Hills Ranch Partnership received approval to subdivide the site into 130 homes. Pulte Home Corporation will develop the project and reduce the project to 127 homes. The proposed products will require modifications to the conditioned side yard setback standard. The condition describes a side yard set back measurement of 5 and 10 feet from the edge of the building pad. The City standard is a measurement from the property line. The project condition creates an unneccesary hardship for several lots generally located upon streets with grades ranging from 6 to 12 percent. All of the lots will be designed to meet a minimum set back of 5 feet and 10 feet from the property line and a minimum distance between dwelling units of 15 feet. The separation of dwelling units is further assured through the street grades and pad elevations of this hillside development. Staff is authorized by the Code to consider and approve the proposed modifications. All homes within the project are subject to Development Review before the Planning Commission. The Mitigation Monitoring Program adopted by the City Council with approval of VTTM No. 52267 contains a mitigation measure requiring a replacement ratio for the loss of coastal sage scrub habitat on the developed portion of the site. The applicant has requested a modification as outlined in the attached Addendum. The City's environmental and biological consultants have reviewed and approved the request. The Final Tract Map 52267 has been reviewed by the appropriate agencies (Diamond Bar Public Works, Los Angeles County Department of Public Works, Walnut Valley Water District, etc.) and has been found to be technically correct and conforms substantially to the approved vesting tentative tract map. The final map meets the requirements of the conditions of approval. ATTACHMENTS: 1. Instructions to Escrow 2. Entry Permit 3. Grant Deed 4. Subdivision Agreement 5. Addendum to Final EIR 6.

The Guidelines Section 15164(a) states that "the lead agency or a responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred." Pursuant to Guidelines Section 15162, a subsequent EIR is only required when: a) substantial changes are proposed in the project which will require major revisions of the environmental impact report because of the involvement of new significant environmental effects or substantial increase in the severity of previously identified effects; or b) substantial changes in the circumstances under which the project is undertaken that would require major revisions to the previous EIR because of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or c) new information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows that: (1) the project will have one or more significant effects not discussed in the previous EIR; or (2) significant effects previously examined will be substantially more severe than shown in the previous EIR; or (3) mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project but the project proponent declines to adopt the mitigation measure or alternative; or (4) mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects but the project proponent declines to adopt the mitigation measure or alternative. The circumstances outlined above in Section 15162 that would require preparation of a subsequent EIR have been determined to not be applicable to the proposed revision of Mitigation Measure 15 to reflect the provisions of the Biological Resources Management Plan (BRMP) because: 'J—u+� PAMMum LIK-02070o.wpd 1-1 Table of Contents VTTM No. 52267 Addendum to Final EIR a) the revision to Mitigation Measure 15 does not involve any changes to the proposed project. The same number of residential dwelling units are being constructed within the same impact footprint as analyzed in the Final EIR; b) there are no substantial changes in the circumstances under which the project is being developed that would require major revisions to the Final EIR. The proposed number of lots are being developed within the same impact footprint analyzed in the Final EIR; and, c) there is no new information available that was not known and could not have been known at the time the Final EIR was certified. The preparation of the BRMP is not new information; its development is a provision of EIR Biological Resources Mitigation Measure 1, and BRMP approval by the City is a pre -requisite for issuance of a grading permit. Additionally, Mitigation Measure 15, as originally written, acknowledged that "CSS mitigation sites will be determined in the Biological Resources Management Plan (BRMP) developed for the VTTM No. 52267 project". Therefore, in accordance with Guidelines Section 15164, an Addendum to the previously certified VTTM No. 52267 Final EIR is the appropriate environmental documentation for the proposed revision to Mitigation Measure 15. The proposed modifications to Mitigation Measure 15 are described in Section 2, Project Description, of this Addendum to the Final EIR for VTTM No. 52267. The Biological Resources Management Plan (BRMP) that resulted in the proposed revision to Mitigation Measure 15 is itself required by Mitigation Measure 1 of the Final EIR. The BRMP is provided in Appendix A to this Addendum. All other provisions of the certified Final EIR and the Mitigation Monitoring Program adopted by the City Council will remain unchanged. 1.2 Overview of Final EIR Certification Final EIR 97-2 (State Clearinghouse # 97031005) was certified by the Diamond Bar City Council on October 6, 1998, and the Findings of Fact, a Statement of Overriding Considerations, a Mitigation Monitoring Program and the project were approved. As required by CEQA, a Notice of Determination was filed with the Los Angeles County Clerk and State Clearinghouse subsequent to the Council's approval of the VTTM No. 52267 project. R:Tr0j9CtS 0B8N003 Addendum EIR-020700.wpd 1-2 Table of Contents SECTION 2 PROJECT DESCRIPTION 2.1 Project Location VTTM No. 52267 Addendum to Final EIR VTTM No. 52267 is a 339.3 -acre site generally located east of Diamond Bar Boulevard and north of Grand Avenue. The site is surrounded by predominately single-family residential development, open space, and vacant land. Land uses adjacent to the VTTM No. 52267 site include: • North—Gold Rush Drive and existing single-family residences. • Northeast—Existing single-family residences along Highcrest Drive and Leyland Drive. • South—Existing single-family residences along Steep Canyon Drive and Grand Avenue, and open space. The vacant open space is a part of VTTM Nos. 52267 and 31479. • East—Open space within VTTM No. 52267 and existing single-family residences. • West—Diamond Bar Boulevard and existing single-family residences furtherto the west. The VTTM No. 52267 site is located in Planning Area 2 of the City of Diamond Bar General Plan and is designated Planning Area 2/Specific Plan (PA-2/SP); PA-2/SP permits residential development. The General Plan notes that "Appropriate land uses for ... (Planning Area 2) include a maximum of 130 single-family detached residential dwelling units concentrated along the anticipated extension of Highcrest Drive, with a minimum of 75 percent of the total 400 -acre area set aside as dedicated open space." 2.2 Description of Approved Project The approved VTTM No. 52267 project consists of a gated community of 130 single-family detached residences clustered on approximately 65 acres of the site (inclusive of streets, manufactured slopes, and a water tank site). This proposed development was evaluated in the Draft EIR for the VTTM No. 52267 site prepared in July 1997. Approximately 273.6 acres (80.7 percent) of the site will remain in natural open space. The 130 single-family detached residential dwelling units would be located along the proposed extension of Highcrest Drive to an intersection with Diamond Bar Boulevard at Tin Drive. Grading for the residential development will be balanced on the site. Proposed grading would involve approximately 1.8 million cubic yards of cut and 1.8 million cubic yards of fill. The 273.6 acres of open space are being dedicated to the City of Diamond Bar and set aside as public open space as set forth in the City's General Plan for Planning Area 2. Additionally, 86.3 acres (all of VTTM No. 52308) were dedicated to the City as public open space as part of the approval of VTTM No. 52267. 2.3 Proposed Mitigation Measure Revision The project action evaluated in this Addendum to the Final EIR is the modification to Mitigation Measure 15 of the Mitigation Monitoring Program adopted by the City Council when it certified the Final EIR for VTTM No. 52267. As originally written, Mitigation Measure 15 read as follows: kTrojectsOBar0003 Addendum EIR-020700.wpd 2-1 Project Description VTTM No. 52267 Addendum to Fina! ElR "15. The goal of the coastal sage scrub (CSS) mitigation program is to develop two acres of replacement coastal sage scrub habitat for each acre (2:1 ratio) lost to development. Replacement at the 2:1 ratio shall be achieved through implementation of the following approaches on suitable undeveloped portions of the VTTM No. 52267 site or on suitable portions of Lot 9 of Tract 31479: restoration of degraded CSS habitat; development of new CSS habitat in or adjacent to areas of highly disturbed native vegetation; or a combination of these approaches. Side slope revegetation of manufactured slope areas may constitute a portion of the CSS mitigation, as long as suitable conditions are present. The location of the CSS mitigation sites will be determined in the Biological Resources Management Plan (BRMP) developed for the VTTM. No. 52267 project. The following revegetation program will apply to all areas impacted but not replanted with coast live oak and/or walnut woodland species or required for fuel modification. Revegetation shall be implemented in stages. The initial stage will begin during site grubbing and will consist of crushing/mulching scrub, within areas to be graded, with a dozer. The crushed/mulched material along with the top four to six inches of topsoil will then be removed in one operation with a loader or dozer and stockpiled nearby as directed by the project biologist......." The revised Mitigation Measure 15 is proposed to read as follows: 15. The goal of the coastal sage scrub (CSS) mitigation program is to provide a three part mitigation program, as specified in the Biological Resources Management Plan (BRMP) prepared by the applicant and approved by the City of Diamond Bar, that would provide for: preservation of 106.6 acres of onsite CSS habitat; preservation of 13.19 acres of CSS habitat offsite through the dedication of VTTM No. 52308 to the City of Diamond Bar; and and hydroseed revegetation with CSS species of approximately 13 acres of graded slopes on the VTTM. No 52267 project site. In total, 132.79 acres of coastal sage scrub mitigation would be provided for the approximate 18.7 acres of onsite habitat that would be impacted by development. This would constitute a mitigation ratio of 7.1 to 1 ( 7.1 acres of preserved/revegetated habitat for each acre of CSS habitat lost to development). 2.4 Focus of Environmental Analysis The analysis in this addendum focuses on the biological resources impacts of the modification to Mitigation Measure 15 of the VTTM No. 52267 Final EIR. R:XProj"VBar%JO03Addendum eiR-020700.wod 2-2 Project Description VTTM No. 52267 Addendum to Final EIR SECTION 3 COMPARATIVE ENVIRONMENTAL EVALUATION This section analyzes the potential effects to biological resources that would result from the proposed revision to Mitigation Measure 15 described in Section 2. 3.1 Biological Resources Impacts Final EIR 97-2 indicated that the VTTM No. 52267 project would impact a variety of biological resources within the approximate 65 acres that would be developed with single-family residential uses. The following biological habitats were identified in the EIR as being impacted by the development of VTTM No. 52267: TABLE 1 VTTM NO. 52267 BIOLOGICAL IMPACTS Venturan-Diegan Transitional Coastal Sage Scrub 125.2 18.7 106.6 Scrub Oak Chaparral 37.7 8.5 29.2 Poison Oak Chaparral 0.9 0.0 0.9 Annual Grassland 67.7 27.7 40.0 Ruderal 4.2 0.0 4.2 Mule fat Scrub 1.3 0.0 1.3 Southern Willow Scrub 0.9 0.0 0.9 Southern Sycamore Riparian Woodland 1.7 0.0 1.7 Coast Live Oak Woodland Coast Live Oak Trees Walnut Trees 48.3 Unknown Unknown 9.6 410 trees 20 trees 38.7 Mexican Elderberry Woodland 4.5 1.1 3.4 Walnut Woodland 40.1 0.0 40.1 Disturbed/Developed Areas 6.7 0.1 6.6 Total 339.3 65.7 273.6 Source: EIR 97-2, VTTM No. 52267, adopted October 6, 1998 The adopted Final EIR and Mitigation Monitoring Program approved by the City Council specified mitigation measures to address the biological resources impacts noted in Table 1. The revisions to the Mitigation Measure 15 would not change the acres of habitats impacted by the proposed project. As originally written, Mitigation Measure 15 required the development of 37.4 acres of revegetated CSS habitat (2:1 ratio). The mitigation measure provided that a portion of this requirement could be met through "side slope revegetation of manufactured slope areas......., as long as suitable conditions are present." The BRMP, which has been reviewed and approved by the City's RAProject War0M AddeMum EIR-020700.wpd 3-1 Comparative Environmental Evaluation VTTM No. 52267 Addendum to Final EIR biological consultant, indicates that suitable conditions are presentwithin manufactured slopes with south, east, and interior orientations for revegetation (Figure 6 of BRMP. Approximately 13 acres of manufactured slopes would be hydroseeded with a mix of CSS vegetation (BRMP, page 6). The balance of the 37.4 acres that would need to be addressed for compliance with Mitigation Measure 15 as originally written, equals 24.3 acres (37.7 acres minus 13 acres of hydroseeded slopes). The revised mitigation measure incorporates the provisions of the BRMP that relate to manufactured slope revegetation and would therefore also comply with the manufactured slope revegetation component of the original Mitigation Measure 15. Subsequent to certification of the Final EIR, the BRMP was prepared. During development of the revegetation and oak tree replacement elements of the BRMP, the applicant's biological consultant determined that local agencies responsible for biological resources mitigation in Southern California, as well as state and federal resources agencies, were preferring preservation of existing CSS habitat instead of revegetation programs. This emphasis recognizes the inherently long periods needed for the establishment of CSS revegetation (typically 5-10 years) and the relatively limited success of revegetation in providing habitat that supports wildlife species. The BRMP analysis indicates that the provision of the 106.6 acres of onsite and 13.19 acres of offsite CSS habitat would provide greater compensation for the 24.3 acres of additional CSS revegetation that were specified by the original Mitigation Measure 15 because the preserved CSS areas are relatively large blocks of high quality contiguous habitat that would provide more biological resources value to wildlife than would a revegetated 24.3 -acre area. The City's biological consultant has validated this conclusion. Considering these factors, it appears that the revision to Mitigation Measure 15 generated by the BRMP is a viable CSS mitigation program and that new significant impacts to biological resources on the 273.6 -acre undeveloped portion of the 339.2 -acre project site would not occur. Further mitigation is not required. 3.2 Other Impacts The proposed revision to Mitigation Measure 15 would not affect any other environmental impact topics evaluated in the Final EIR for VTTM No. 52267.

PURPOSE AND GOALS OF THE BIOLOGICAL RESOURCE MANAGEMENT PLAN The purpose of this Biological Resource Management Plan (BRMP) is to meet the requirements of the Mitigation Monitoring Program (MMP) for Vesting Tentative Map No. 52267, and to provide details for the mitigation of coast live oak woodland, Diegan coastal sage scrub, walnut woodland, and streambed impacts within the approved project, as required by the project's certified Final Environmental Impact Report (EIR) (City of Diamond Bar 1997). The goal is to restore and enhance habitat values within slope areas created by project grading to mitigate for habitat that would be disturbed by construction of the proposed prof ect. The restored areas are expected to approach the function and value of their pre -disturbed states in the future. Condition 1 of the MMP states the following: 1. Prior to the issuance of a grading permit, a Biological Resource Management Plan (BRMP) will be submitted to the City of Diamond Bar for approval. This BRMP will specify design and implementation of biotic mitigation measures, including habitat replacement and revegetation (in temporary impact areas), protective measures during construction, performance (growth) standards for replacement habitat, maintenance criteria, and monitoring requirements. The Draft BRMP will also be reviewed by the United States Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDFG), and the United States Army Corps of Engineers (USACE) as applicable to their jurisdictions. The primary goal of the BRMP will be to ensure the long -tern perpetuation of the existing diversity of habitats in the preserved areas and adjacent development transitional areas. The BRMP shall contain at a minimum the following: a. Identification of habitats (including individual oak and walnut woodlands) to be removed, and the locations where these habitats are proposed to be restored or relocated. b. Procedures for vegetation analyses of adjacent protected habitats to approximate their relative composition, and site preparation activities (clearing, grading, weed eradication, soil amendment, topsoil storage), irrigation, planting (container plantings, seeding), and maintenance (weed control, irrigation system checks, replanting). This information will be used to determine the mitigation requirements in the revegetation areas. C. Sources of plant materials for mitigation areas and methods of propagation. d. Specifications for maintenance and monitoring of re-established habitats, including weed control measures, frequency of field checks, and monitoring reports for temporary disturbance areas. - e. Specifications and performance standards for growth of re-established plant communities. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 1 f. Remedial measures to be implemented if performance standards are not met. g. Methods and requirements for monitoring of the restoration/replacement areas. h. Measures for topsoil preservation and erosion control. i. Location of protective fencing around environmentally sensitive areas and construction staging areas. Prior to initiation of any site grading or equipment mobilization onto the project site, an eight foot high chain link fence with a two foot long cantilever section angling inward (toward the site) shall be installed along the western site boundary abutting Diamond Bar Boulevard and extending from the northern boundary of the Los Angeles County Flood Control Easement (near Steep Canyon Road) to Gold Rush Drive, and extending easterly along Gold Rush Drive for a distance of approximately 400 feet to the property boundary comer. The fence shall be maintained and shall remain in place until the first occupancy permit is issued by the City of Diamond Bar. Specification of the purpose, type, frequency, and extent of chemical use for insect and disease control operations as part of vegetative maintenance within sensitive habitat areas. k. Specific measures for the protection of sensitive habitats to be preserved. These measures will include, but are not limited to, erosion and siltation control measures, protective fencing guidelines, dust control measures, grading techniques, construction area limits, and biological monitoring requirements. During development of the final landscape plan and project entry design plan, the City's biological consultant shall work with the applicant to ensure that provisions are incorporated into these plans that would not limit wildlife movement across the project entry road and adjacent manufactured slopes. The BRMP is separated into separate sections for coast live oak woodland/walnut woodland mitigation and streambed mitigation, Diegan coastal sage scrub mitigation, and "other" mitigation as required by the MMP. Portions of the restoration planning requirements will be the same for all of the habitats being restored. These sections will be provided in the Diegan coastal sage scrub section, and will not be repeated in the remaining habitat sections. II. PROJECT SUMMARY A. PROJECT DESCRIPTION AND LOCATION The project site is located on 339.3 acres in the City of Diamond Bar in southeastern Los Angeles County (Figures 1 and 2). The site is surrounded by low- to medium -density residential areas. The City of Diamond Bar has designated the property as PAZ -Residential for 130 units, which permits residential, commercial, recreational, public facilities, and other land uses (MBA 1992).

The lot building pads will be a minimum of 6,000 square feet each. Primary access to the property will be from Diamond Bar Boulevard to the west, while secondary access will be from Hillcrest Drive in the residential area to the east. Of the 339.3 -acre site, approximately 65.7 acres will be impacted with 273.6 acres on site left undeveloped. Included within the impacted areas are residential lot pads, one water reservoir, fill slope areas, and most of the fuel modification zones. In some areas, the irrigated fuel modification zone (first 100 feet) extends beyond the graded areas into open space and is considered an impact. Approximately 5.4 acres of the 65.7 acres being impacted is accounted for by fuel modification zones outside of graded areas. B. ENVIRONMENTAL SETTINGISITE CONDITION DESCRIPTION The project site is situated amid the eastern portion of Puente Hills. The site drains generally east to west via several deep ravines divided by steep and narrow ridges. To the east lie the Chino Hills while to the north lie the San Jose Hills. Present land use on site is restricted to power lines operated by Southern California Edison; otherwise, the land is undeveloped. Residential and commercial developments surround the property. Since the project site is completely surrounded by development, it is considered an island of habitat from a wildlife movement standpoint. Local populations of animals likely are self-contained within the site, benefitting from natural movement corridors between the various on-site topographic features. Some interchange of wildlife from off-site open space, especially birds and larger mammals likely occurs to the west into city park lands. Elevation of the site ranges from approximately 800 to 1,330 feet above mean sea level. Eleven vegetation communities occur on the project site: Diegan coastal sage scrub (including disturbed), coast live oak woodland, walnut woodland, southern sycamore riparian woodland, elderberry woodland, mule fat scrub, southern willow scrub, scrub oak chaparral, poison oak chaparral, ruderal, and annual grassland (Figure 3). Disturbed and developed areas also occur on the site. The Diegan coastal sage scrub on site dominates south -facing slopes and also occurs in patches amid the coast live oak woodlands on the project site. Some of the typical plants found within the Diegan coastal sage scrub on site include California sagebrush (Artemisia californica), California buckwheat (Eriogonum fasciculatum), laurel sumac (Malosma laurina), black sage (Salvia mellifera), and coastal prickly -pear (Opuntia littorahs). Much of the Diegan coastal sage scrub on site appears to have reached the climax stage, due to the high degree of shrub overlap and very low herbaceous cover. On-site disturbed portions of Diegan coastal sage scrub have a higher component of annual grasses and noticeably less shrub cover than undisturbed Diegan coastal sage scrub areas. Approximately 125.3 acres of this plant community occur on site, 0.4 acre of which is disturbed.

Project boundary ... ...... . Waters of the U.S. 12' :'= Project impact area . .... ..... Coast live oak woodland occurs in the outer portion of the central California coastal mountain ranges and extend south into Baja California, Mexico occurring between 500 and 4,500 feet in elevation. The dominant plant in the on-site oak woodlands is coast live oak (Quercus agrifolia), which typically reaches a height of 12 to 70 feet, forming an incompletely closed canopy, with an understory herbaceous layer approaching 80 percent cover. Minor tree components include California walnut Ouglans californica), blue elderberry (Sambucus mexicana), and western sycamore (Platanus racemosa). Shrub components are primarily composed of toyon (Heteromeles arbutifolia) and poison oak (Toxicodendron diversilobum). On the project site, coast live oak woodland is found mainly along steep, north -facing slopes and in ravines. It intergrades with walnut woodland and scrub oak chaparral on xeric slopes and with southern sycamore riparian woodland in drainage courses. Areas within drainages have the most dense canopy. The coast live oak woodland on site is of an overall high diversity and quality. Approximately 48.3 acres of coast live oak woodland occur on site. Walnut woodland occurs from the south side of the San Gabriel Mountains to the Santa Ana Mountains, mostly between 500 and 3,000 feet above mean sea level. On the project site, it is dominated by the California walnut, with coast live oaks and blue elderberries as more minor components and a well developed understory of shrubs and herbaceous species. Some of the typical shrub understory components include toyon, poison oak, scrub oak (Quercus berbidifolia), laurel sumac, black sage, and fuscia- flowered gooseberry (Ribes speciosum). This habitat occurs primarily on the north -facing slope adjacent to an unnamed stream that passes adjacent to Steep Canyon Road in the central portion of the project site. Approximately 40.1 acres of this woodland occur on site. Two primary regional issues to consider are the presence of wildlife corridors and the importance of the habitats on site. The project site does not function as an important regional wildlife corridor because it is entirely surrounded by development. Local corridors likely exist between the northern and southern ends of the site, but these are restricted to use by the resident animal species. From a habitat standpoint, the site supports a variety of undisturbed native plant communities, some of which are restricted in distribution. Habitats that are of special regional importance include coast live oak woodland, Diegan coastal sage scrub, walnut woodland, southern sycamore riparian woodland, and southern willow scrub. Since the City of Diamond Bar was incorporated, it has used the Los Angeles County Development Code temporarily pending completion of its own code. The County of Los Angeles identified the Tonner Canyon/Chino Hills area within the City of Diamond Bar sphere of influence as part of Significant Ecological Area (SEA) No. 15. The Tonner Canyon/Chino Hills SEA was established to preserve some ofthe remaining undisturbed stands of oak woodlands, walnut woodlands, coastal sage scrubs, chaparral, and riparian woodland in eastern Los Angeles County. An SEA Technical Advisory Committee was established for evaluating all projects in the City of Diamond Bar in and adjacent to the Tonner Canyon/Chino Hills SEA for potential effects to resources within the SEA. The project does not impact the Tonner Canyon/Chino Hills SEA and has the added benefit of preserving target habitats which are also being conserved within the SEA. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 4 C. PROJECT IMPACTS Approximately 18.7 acres (15 percent) of Diegan coastal sage scrub, 9.6 acres (20 percent) of coast live oak woodland (4 10 individual oaks), 1.1 acre (25 percent) of elderberry woodland, 8.5 acres (23 percent) of scrub oak chaparral, 27.7 acres (41 percent) of annual grassland, and 0.1 acre (1 percent) of disturbed/developed will be impacted by the project (Figure 4). This is more fully described in the certified Final EIR (City of Diamond Bar 1997). D. MITIGATION NEEDS 1. Diezan Coastal Sage Scrub Mitigation for Diegan coastal sage scrub will include three mitigation measures: 1) On-site dedication of 106.6 acres (85 percent) of Diegan coastal sage scrub to open space; 2) Off-site dedication of 13.19 acres of Diegan coastal sage scrub as part of the 86.25 acre dedication of VTM No. 52308 to the City of Diamond Bar (Figure 5); and 3) restoration of approximately 13 acres of fill slopes outside of areas required for fuel reduction zones with Diegan coastal sage scrub species. Approximately 125.3 acres of Diegan coastal sage scrub occur on site, withthe largest contiguous blocks located in the southern half of the site. Two fairly large blocks of habitat do occur along the western and eastern edges of the northern half of the site. None of the Diegan coastal sage scrub on site is occupied by the coastal California gnatcatcher (Polioptila californica californica). Approximately 18.7 acres (15 percent) of Diegan coastal sage scrub will be impacted by the project. A majority of the Diegan coastal sage scrub impacts occurs as small patches of five acres or less in size and along the fringes of the larger patches in the northern portion of the site. In addition to the 106.6 acres (85 percent) retained on site (a majority of which occurs in larger contiguous blocks), graded slope areas on the project will be revegetated with Diegan coastal sage scrub (Figure 6). These areas total approximately 13 acres. This results in an on-site preservation ratio of 6.4:1. In addition to the habitat preserved and restored on site, an additional 13.19 acres of Diegan coastal sage scrub and 1.72 acres of coast live oak woodland will be preserved off site as part of the 86.25 acre dedication of VTM No. 52308 to the City of Diamond Bar (Figure 5). This brings the total on- and off-site preservation ratio for Diegan coastal sage scrub to 7.1:1. Regional Context Mitigation for impacts to Diegan coastal sage scrub can include on- and/or off-site habitat preservation, habitat restoration, or both. More recently, habitat restoration has been limited to key corridor areas and restoration of project slopes adjacent to preserved habitat in a majority of the jurisdictions in southern California, with the focus primarily upon on- and off-site preservation.

Habitat Plannine Programs Jurisdictions such as the City and County of San Diego and the County of orange have implemented habitat -planning programs such as the Multiple Species Conservation Program as part of the Natural Communities Conservation Program (NCCP). Within these plan areas, preservation areas and impact areas have been identified, and mitigation ratios have been established. Prior to the implementation of these plans, mitigation ratios varied from less than 1:1 to up to 3:1. Upon implementation of these plans, the ratio has been standardized, with the ratio varying from 1:1 to 2:1 depending on the plan, and the location of the impacts and preservation relative to regional preserves. Mitigation requirements within these plan areas focuses on habitat preservation rather than habitat restoration. The on-site preservation ratio for Diamond Hills Ranch of 5.7:1 exceeds ratios required for arty of these plans, and is also much higher than what was typically required prior to implementation of these plans. Similarly, the oak woodland preservation ratio is higher than that typically required, and when combined with proposed on-site restoration, will result in no net loss of oak woodland on the property. Occupation by the Coastal California Gnatcatcher Some jurisdictions (i.e., County of Riverside) typically have higher mitigation ratios for Diegan coastal sage scrub that is occupied by the coastal California gnatcatcher. Additionally, if the habitat is occupied, the U.S. Fish and Wildlife Service (Service) retains jurisdiction under the Federal Endangered Species Act. For jurisdictions not enrolled in NCCP such as the City of Diamond Bar, the Service typically recommends mitigation ratios for occupied habitat impacts of 2:1 to 3:1. The Service does not have jurisdiction over unoccupied habitat for jurisdictions not enrolled in the NCC?, however. The Diegan coastal sage scrub on site is not occupied by the coastal California gnatcatcher, and the closest known occupied habitat is at least five miles from the site. On-site Preservation and On-site Preserve Value Mitigation ratios typically vary depending on the long-term habitat value of areas being retained in open space. Larger contiguous blocks of habitat have higher value than small blocks of habitat. Additionally, habitat that is connected to other habitat blocks off site is of higher habitat value. Approximately 273.6 acres of habitat including 106.6 acres of Diegan coastal sage scrub are being retained in contiguous open space on site. If the oak woodland restoration occurs on site, it will add to the overall value of the habitat on site. A 273 -acre block of habitat is large enough to support a diversity of wildlife over the long term, provided there is periodic interchange of genetic stock from other sites, especially for bird species. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 6 Habitat Ouality Habitat quality of both the habitat impacted and the habitat preserved often affects mitigation requirements, especially in jurisdictions that do not have a jurisdiction -wide habitat planning process in place. The Diegan coastal sage scrub and oak woodland habitat being retained on site is the highest quality habitat on the parcel. Given these factors, the amount and quality of Diegan coastal sage scrub habitat being retained on and off site would fully mitigate project impacts to this habitat. 2. Coast Live Oak Woodland/Walnut Woodland Mitigation for coast live oak woodland and individual walnut trees would be accomplished by on-site dedication of 38.7 acres (80 percent) of coast live oak woodland, 40.1 acres (100 percent) of walnut woodland, off-site dedication of 1.72 acres of coast live oak woodland (VTM #52267, secondary parcel) and restoration of coast live oak woodlands and walnut trees on site (Figure 6). Based on the Los Angeles County Oak Tree Ordinance, the amount of oak transplantation is established based on the diameter and number of oaks impacted at a replacement ratio of 2:1. A total of 1,116 coast live oaks will be planted in fill slopes. Since 20 to 30 California walnuts are scattered within the coast live oak woodlands being impacted on site, they should be part of the restoration. It is recommended that impacted walnuts be replaced with 40 replacement trees. The table below summarizes the size of trees recommended for mitigation in the oak tree ordinance. < 36" Trunk DBH (diameter at breast height) 2:1 replacement one 5 -gallon container size and one transplant tree 36-38" Trunk DBH 3:1 replacement one 5 -gallon, one 15 - gallon, and one transplant tree > 48" Trunk DBH 4:1 replacement one 5 -gallon, two 15 - gallon, one 24 -inch box, and one transplant tree Note: If a sufficient quantity of healthy and/or accessible existing oaks is not available for transplantation, then the following will apply as a substitution for the one transplanted oak noted above for each DBH/ratio category: HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 7 < 3611: substitute one 15 -gallon size for one transplant 36-48": substitute one 15 -gallon for one transplant > 4811: substitute one 24 -inch box size for one transplant Based on these requirements, 412 five -gallon oaks, 445 15 -gallon oaks, and twenty-four 24 -inch box oaks would be needed to mitigate the project. The mitigation plan has been increased based on input from the City to include 432 one -gallon oaks, 643 15 -gallon oaks, 41 60 -inch box oaks, and 40 15 -gallon walnuts. III. ESSENTIAL PLAN PARTICIPANTS The restoration plan does include habitats under federal and state jurisdiction, with associated discretionary actions therefore required. Impacts to 0.05 acre of jurisdictional Waters of the U.S. qualify under the Nationwide 26 permit process with the U.S. Army Corps of Engineers. Impacts to 5.22 acres of oak woodland within drainages and 0.05 acre of streambed habitat are considered California Department of Fish and Game (CDFG) jurisdictional. A 1603 Agreement application was submitted; however, CDFG did not respond within the 30 -day time frame, so no additional measures are incorporated into the BRMP. A. PROJECT PROPONENT The project proponent, Diamond Hills Ranch Partners, will be responsible for financing the installation and monitoring of the mitigation sites. The contact at Diamond Hills Ranch Partners is Mr. Larry Lazar. He can be reached by telephone at (714) 693-6700, or at the address given on the title page of this document. B. LANDSCAPE ARCHITECT Landshapes, a licensed landscape architect will prepare the construction documents to implement this plan. The construction documents will be reviewed and approved by a restoration specialist and the City of Diamond Bar. The restoration specialist will be under contract to the City. A landscape architect will also be responsible for inspecting certain parts ofthe installation, and for participating in the final installation inspection. C. RESTORATION SPECIALIST Overall supervision of the installation and maintenance contractors and monitoring in the mitigation area will be the responsibility of a restoration specialist or a biologist familiar with native habitat restoration. The restoration specialist will be under contract to the City and will educate all contractors with regard to mitigation goals and requirements. This education will be initiated at a pre -construction meeting. After each monitoring event, the restoration specialist will provide the project proponent and installation contractors with a written list of items in need of attention. All requests for work which go beyond the contractor's scope of work will first be approved by the project proponent. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 8 D. INSTALLATION CONTRACTOR The installation contractor is responsible for pre -planting weed control, topsoil salvage, and imprinting and seeding. Imprinting is described in Section 6.F. (Planting Timing and Methods) and in Appendix A. Once the restoration specialist has verified the completion of the landscape installation, a 180 -day establishment period will begin. At the end of this period, the restoration specialist will certify completion of the installation contract, provided all installation and maintenance tasks have been finished. These items include, but are not limited to, weed control, dead plant replacement, and reseeding. The installation contractor will be educated as to the installation and maintenance of native plants. E. MAINTENANCE CONTRACTOR After the installation contract is completed, a maintenance contractor will be hired by the project proponent for the duration of the five-year monitoring period. The project proponent may change contractors at its discretion. The maintenance contractor will service the entire restoration area at least once a month. The maintenance contractor will meet the restoration specialist at the site, when requested, and will perform all checklist items in a timely manner. The maintenance contractor will be educated by the restoration specialist as to the maintenance of a native plant habitat and the difference between native plants and weeds. IV. RESTORATION DESIGN CONCEPTS The goal ofthis restoration plan is to establish Diegan coastal sage scrub and oak woodland based on species composition from these vegetation communities on the site. The total amount of restoration area encompasses approximately 21 acres of Diegan coastal sage scrub and coast live oak woodland on manufactured slopes. All proposed upland restoration is associated with permanent project related impacts (Figure 6). All areas will be imprinted with a non -irrigated seed mix. If technically feasible, topsoil will first be reapplied on these areas (see Section 6.A. of this report). V. RESTORATION PLAN IMPLEMENTATION GUIDELINES A. TIMING FOR SEEDING All imprinting and/or broadcasting of seeds will be done between September 15 and January 15. B. PROTECTION OF HABITAT OUTSIDE THE RESTORATION AREAS DURING PROJECT CONSTRUCTION Prior to initiation of any site grading or equipment mobilization onto the project site, a six-foot high chain link fence with a two foot long cantilever section angling inward (toward the site) shall be installed along the western site boundary abutting HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 9 Diamond Bar Boulevard and extending from the northern boundary of the Los Angeles County Flood Control Easement (near Steep Canyon Road) to Gold Rush Drive, and extending easterly along Gold Rush Drive for a distance of approximately 400 feet to the property boundary corner. The fence shall be maintained and shall remain in place until the first occupancy permit is issued by the City of Diamond Bar. Extant habitat to be preserved adjacent to restored habitat will be marked with stakes and flagging prior to construction. Construction crews will be advised to avoid impacts to preserved habitat. Unanticipated impacts to preserved habitat must be mitigated as recommended by the restoration specialist at the expense of the company or persons responsible. C. PROTECTION OF ADJACENT HABITAT DURING RESTORATION Specific staging areas will be established, and restoration areas will be delineated and marked as described above. All restoration activities and related disturbance will remain within the designated areas. in conjunction with construction activity, the grading contractor shall control dust accumulation on natural vegetation at the source of disturbance by standard wetting techniques. Under the guidance of the project biologist, natural vegetation shall be periodically sprayed with water to reduce dust accumulation on leaves. D. PERMANENT PROTECTION OF RESTORED AREAS The interface between native habitats and restoration areas will be clearly marked as described above. Work will be monitored by the restoration specialist to ensure that construction does not exceed these limits. If unanticipated impacts do occur, the affected areas will be restored as recommended by the restoration specialist and to the satisfaction of the City of Diamond Bar. VI. RESTORATION PLAN DETAILS A. REUSE OF TOPSOIL Topsoil from areas that currently support Diegan coastal sage scrub and are being impacted will be collected and reused. Topsoil contains a viable and valuable seed bank as well as site-specific soil microbes. The restoration specialist will flag the collection areas to avoid collecting weed -infested soil. The restoration specialist will also determine the depth of removal for topsoil salvage. It is expected to be approximately six inches. Prior to collection of topsoil from undisturbed shrublands, the contractor will drive over the collection site(s) to crush the vegetation. Note: the collection sites will be flagged by the restoration specialist. The Diegan coastal sage scrub vegetation will be collected, mulched, and stockpiled. Then, the top six inches of soil will be removed and stockpiled from the mulched vegetation. The soil and mulch will be applied to the restoration areas, if technically feasible, within six months of initial HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 10 removal. These materials can be stockpiled up to six feet deep for up to six months if they are kept dry. To that end, measures may be necessary to protect the stockpiled topsoil (e.g., covering), depending on direction by the restoration specialist. B. SEED SPECIFICATIONS It is preferred that all propagules used at the site be from within the site or from wild sources within Los Angeles County and as close to the site as possible. Seed will be cleaned to a grade normally acceptable in the seed trade with all sticks and large plant parts removed. Storage costs and insurance will be included in the price per pound of seeds. Seeds will be tested for percent purity, percent germination, and the number of live seeds per pound. Testing costs will be included in the seed costs per pound and will be the responsibility of the seed supplier. Results of the seed tests should be made available to the restoration specialist prior to seed delivery. Seed collections, handling, and storage techniques will be observed by the restoration specialist. Table l lists species to be included in the seed mixes, subject to availability. Modifications to the list may be necessary and may include substitute species in the mix and/or modification of the pounds per acre of available seed. If adequate seed is not available from local sites, a commercial source may be used to supplement seed supply, based on direction by the restoration specialist.

CONTRACT GROWING/PLANT SOURCES Arrangements will be made by the installation contractor or the project proponent to acquire seed required for restoration. An additional 15 percent of the total amount of seed mix will be procured. A copy of this contract will be submitted to the restoration specialist by the owner or installation contractor as verification. Seed collection/acquisition will be conducted by an experienced native plant nursery or seed company such as, but not limited to, S&S Seeds of Carpinteria, California. The contract grower will provide the restoration specialist with information on the sources of all plant and seed materials - grown/collected for the project for final approval. If necessary, the restoration specialist will help the grower locate local sources for plant materials. D. SUBSTITUTIONS The installation contractor is expected to secure all plant materials well in advance of the expected planting date. No species should be substituted without approval of the restoration specialist. If the installation contractor is unable to obtain the proper species specified by the time of planting, commencement of the guarantee period will be delayed until all plants specified are planted for a particular project phase. Substitution of seed species at the time of imprinting depends upon the discretion of the restoration specialist in consultation with the landscape architect. All approved substitutions will be documented by the installation contractor in the final set of "as -built" plans. Lack of planning (i.e., insufficient lead time for seed collection) will not be accepted as justification for substitutions. E. PLANT INSPECTION Installation and monitoring contractors will inspect planted areas and perform maintenance activities as needed according to the five year schedule (See Section 7.0 Maintenance). Specific performance standards have been set by which to evaluate project progress (See Section 8.0 Monitoring). F. SOILS AND SITE PREPARATION Following perennial weed treatment, restoration areas shall be ripped to eight inches. These areas will then be covered with three inches of salvaged topsoil and this shall be ripped in to a depth of six inches. Lastly, a second three inches of salvaged topsoil will be placed over the top. Compaction of these soils will occur during imprinting. On sill slopes, the top three feet of soil will be compacted to no more than 90 percent so that plants will be able to take root. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 13 G. PROTECTION MEASURES In areas where upland restoration sites are adjacent to roads, homes or other potential disturbance sources, protection measures may also include localized fencing to restrict access if deemed appropriate by the restoration specialist. In addition, if problem areas are observed during monitoring and maintenance activities, fencing of such areas may be required by the restoration specialist. H. PLANTING TIMING AND METHODS To take advantage of the rainy season and minimize seed predation, all seeding will occur between November 15 and January 15. Imprinting will be the primary method of seeding. Imprinting is a mechanical means of impressing and embossing smooth- walled V-shaped furrows in the soil surface and spreading the seed (Figure 5). Seeding and inoculating the soil with mycorrhizae are done simultaneously. I. HYDROLOGY The proposed upland restoration sites are located in areas that are suitable for coastal sage vegetation with respect to local hydrologic conditions such as surface runoff and groundwater levels. A number of site-specific measures related to hydrologic conditions will also be implemented as part of the restoration effort or adjacent landscaping plans. Specifically, these include _ imprinting to provide irregular ground surfaces, and directional irrigation techniques in adjacent areas to avoid over -watering the upland restoration sites. Irrigation is proposed for the first several years of the restoration effort for the container plants and trees. J. IRRIGATION PLAN After plant establishment (four years), irrigation will cease. The irrigation schedule will attempt to develop a deep root growth by incorporating evenly spaced, infrequent, deep applications of water. To obtain deep penetration of water, the irrigation system may be activated several times in one 24-hour period. The irrigation system will incorporate the use of moisture sensors connected to an irrigation controller. This will allow for the application of water on an "as -needed" basis. Once the plant material is established and does not require supplemental irrigation, the "above -ground" portions of the system will be removed. The restoration specialist will determine how and when the system will be removed. The goal is to obtain germination and growth with the least amount of irrigation. Frequent irrigation encourages weed invasion and leaches nutrients from the soil. Native plantings that are infrequently irrigated may grow slower initially but will ultimately develop better as habitat. As a result, irrigation will be used for the first three years, or less, of the monitoring period. During the final two years, the monitoring would determine the success of the project without irrigation. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 14 K. SOILS Proposed upland restoration sites are located in previously disturbed areas that formerly supported similar upland habitats. While the physical and chemical nature of topsoils in these areas have been modified from grading or other development activities, native topsoils salvaged from portions of the site that are proposed for development and currently support coastal sage scrub habitats will be used. L. SPECIFIC REQUIREMENTS FOR OAK WOODLAND 1. Planting Requirements I. The host area should be prepared by clearing weeds. Start by digging a hole twice as deep and twice as wide as the plant container. Break up large dirt clods and try to avoid letting the hole be too smooth sided. II. Prepare the fill dirt. Native soil should be used as fill dirt and should be free of large rocks and dirt clods. If a pre -plant fertilizer is added, application rates should be lower than those used for ornamentals. III. Fill planting hole with water and allow it to drain. IV. Refill the hole using the following process: A. Spill some of the fill dirt into the hole, moisten it, and set the plant root ball on top of the moistened soil so that the plant collar is one inch higher than the finished grade of the planting area. _ B. Replace some backfill material up to 2/3 the height of the root ball while allowing water to slowly flow into the hole. At this point install a protective screen around the plant. The preferred type of screening is corrugated mylar, which is clear and rodent -resistant. C. Place the remaining fill dirt in the hole, making sure that the plant collar is still higher than the final grade. Fill dirt should hold the protective screen in place. V. Create an irrigation basin by mounding dirt considerably outside of the hole dimensions. VI. Apply at least one inch of organic, disease and weed free mulch in remainder of basin around plant collar and within the entire irrigation basin. Irrigate from the top, filling the basin with water, to settle the fill dirt and mulch. Repeat this at least once. All planting of container stock will be performed and completed between November 15 and April 30 of each year. All container stock will be healthy, disease free, and of proper size prior to planting. Overgrown, root -bound container stock will be rejected. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 15 2. Field Plant Layout and Suacina of Container Plants The revegetation specialist will approve the final layout of all plant materials in the field, prior to planting, to assure proper placement. No changes in the field will be allowed without written permission from the revegetation specialist. 3. Planting Methods All oak container plants will be planted in a hole at least twice the diameter of the container and twice the depth. Adequate areas will be created to accommodate the oak trees. The top of the root ball will be set one inch above finished grade. The backfill will consist of 50 percent soil from the site and 50 percent soil amendment. A weed -free zone will be established around each container plant, extending at least 18 inches from the base of the plant. 4. Protection From Herbivore The revegetation will occur in an area potentially used by mule deer (Odocoileus hemionus) and brush rabbits (Sylvilagus auduboni). Protective fencing or enclosures will be maintained around tree plantings as long as the trees remain vulnerable to herbivory. Any protective measures around the plantings will be maintained so that they do not interfere growth. For example, if wire enclosures are used and the plantings begin to send branches through the wire, the enclosure will be replaced with a wire enclosure of larger mesh that provides enough room for plant growth. M. COST ESTIMATE Landshapes has prepared a cost estimate for the restoration and a five-year monitoring program. Overall, the cost of this restoration project is projected to be approximately $1,300,000. VII. MAINTENANCE A. GENERAL MAINTENANCE Damage to the restoration areas occurring as a result of unusual weather or vandalism will be repaired as directed by the restoration specialist. The cost of such repairs will be paid for as extra work, although the contractor should provide the typical replacement costs as part of his/her contract. Any damage caused by the maintenance contractor's inadequate maintenance, as determined by the restoration specialist, will be repaired by the contractor at his/her expense. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 29, 2000 16 B. MONITORING/MAINTENANCE SCHEDULE The restoration specialist will monitor the site preparation, seeding, subsequent establishment, and growth in an effortto detect any problems at an early stage (Table 2). Potential problems could arise from weed competition, erosion, vandalism, and unacceptable levels of disease and predation. In addition, the installation and monitoring contractors will inspect planted areas and perform maintenance activities as needed according to the schedule in Table 3. Table 2 M&INTENANCE MONITORING SCHEDULE Phase Schedule Grading/Site Preparation/Installation 2 times per week Post Installation Year 1 Monthly Year 2 Bi -Monthly Years 3-5 Quarterly Table 3 imaNTENANCE SCHEDULE Phase Installation Daily Post Installation Year 1 February -May Year 1 June -January Year 2 Years 3-5 Semi -Monthly Monthly Monthly Bi -Monthly Schedule HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 2B, 2000 17 The restoration specialist's maintenance monitoring program will begin with the construction process, and maintenance by the contractor will commence at the site preparation phase. The restoration specialist will file a written report to the City after completing each inspection. Each of these reports will identify maintenance concerns including mortality, vandalism, and weed - related issues. These reports will facilitate communication and coordination with the installation contractor who will be responsible for implementing the maintenance program. C. WEEDING Weed eradication will be conducted as necessary to minimize competition that could prevent the establishment ofnative species. As weeds become evident, they should be removed by hand, mechanical means, or controlled with the proper systemic herbicides. No weed whips will be permitted after installation of the container stock and seed mixes. The restoration specialist will determine the need for weeding and will notify the project proponent and maintenance contractor of any required work. Maintenance personnel will be trained to distinguish weed species from desirable native vegetation. Examples of weeds to be controlled include, but are not limited to, artichoke, tree tobacco, yellow star thistle (Centaurea melitensis), mustard (Brassica spp.), filaree (Erodium spp), tumbleweed (Salsola iberica), and oats (Avera spp.). Artichoke should receive a foliar application and tree tobacco should be cut and stump treated with herbicide. Two herbicide applications will be made with a minimum of three weeks between applications. D. REPLACEMENT PLANTING As discussed in Section 8.0 Monitoring, remedial measures may be required if any of the restored areas fail to meet the year - five standards. E. TRASH AND DEBRIS REMOVAL Planted areas will be kept free of trash and debris and will be checked according to the maintenance schedule (Table 3) by the installation contractor. F. PEST CONTROL Insects, vertebrate pests, and diseases will be monitored. Generally speaking, a high threshold of tolerance will be permitted before control measures are considered. All specific recommendations will only be made by a licensed pest control adviser as required by law. All applicable federal and state laws and regulations will be closely followed. The restoration specialist will be consulted on any pest control matters. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 18 G. FERTILIZATION Fertilizer will not be applied, except in extraordinary circumstances, and only at the written direction of the restoration specialist. VIII. MONITORING A. SCHEDULE Upon completion of the restoration effort, the restoration specialist will prepare a letter report indicating that the installation is finished and that the five-year monitoring period has begun. Final acceptance of the installation will be verified during a site visit with the restoration specialist, landscape architect, and City staff. Monitoring reports will be submitted to the City semi- annually for the first 3 years, and annually for years 4 and 5. B. CONTENT OF MONITORING REPORTS The annual reports will include botanical observations, including a description of site conditions, plant health, weed growth, plant mortality, seed mix percent germination, etc. Any remedial recommendations will be made in the annual reports. A summary of whether the project is meeting the success criteria will be included. C. SUCCESS CRITERIA The purpose of this section is to define specific performance standards by which to evaluate project progress. The following parameters should be measured to compare the restored areas with a reference site or sites. The reference sites should be in -- Diegan coastal sage scrub within 500 feet of the restoration areas and also should have similar slope and aspect to the restoration areas. The following performance standards shall apply for the revegetation of coastal sage scrub communities: First Year: Coverage/30 percent coverage by n.disturbed vegetative materials, seeded species and container stock. Survival Rate: 90 percent survival of any container stock originally planted. If 90 percent survival has not been achieved, replanting with appropriate size container stock necessary to achieve this standard will be performed. Second Year: Coverage/45 percent coverage by redisturbed vegetative materials, seeded species and container stock. Survival Rate/50 percent survival of any container stock originally planted. If 50 percent survival has not been achieved, replanting with appropriate size container stock necessary to achieve this standard will be performed. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 oQ January � , ---- �nnn 19 Third Year: Coverage/60 percent coverage by redisturbed vegetative materials, seeded species and container stock. Survival Rate/50 percent survival of any container stock originally planted. If 50 percent survival has not been achieved, replanting with appropriate size container stock necessary to achieve this standard will be performed. Fourth Year: Coverage/75 percent coverage by redisturbed vegetative materials, seeded species and container stock. Survival Rate/50 percent survival of any container stock originally planted. If 50 percent survival has not been achieved, replanting with appropriate size container stock necessary to achieve this standard will be performed. Fifth Year: Coverage/90 percent coverage by redisturbed vegetative materials, seeded species and container stock. Survival Rate/50 percent survival of any container stock originally planted. If 50 percent survival has not been achieved, replanting with appropriate size container stock necessary to achieve this standard will be performed. Coastal sage scrub revegetation will be considered successful at five years if the percent cover and species diversity of the restored and/or created habitat areas are similar to percent cover and species diversity of adjacent existing habitats as determined by quantitative testing of existing and restored and/or created habitat areas by the project biologist. Performance standards for coast live oak woodland and walnut woodland are as follows: First Year: Coverage/35 percent. Survival Rate/90 percent survival of all trees, including container stock or cuttings. If 90 percent survival has not been achieved, replanting with appropriate size container stock or cuttings necessary to achieve this standard will be performed. Second Year: Coverage/50 percent coverage by tree and shrub plantings. Survival Rate/90 percent survival of all trees, including container stock or cuttings. If 90 percent survival has not been achieved, replanting with appropriate size container stock or cuttings necessary to achieve this standard will be performed. Third Year: Coverage/70 percent coverage by tree and shrub plantings. Survival Rate/90 percent survival of all trees, including container stock or cuttings. If 90 percent survival has not been achieved, replanting with appropriate size container stock or cuttings necessary to achieve this standard will be performed. Fourth Year: Coverage/80 percent coverage by tree and shrub plantings. Survival Rate/90 percent survival of all trees, including container stock or cuttings. If 90 percent survival has not been achieved, replanting with appropriate size container stock or cuttings necessary to achieve this standard will be performed. Fifth Year: Coverage/90 percent coverage by tree and shrub plantings. Survival Rate/90 percent survival of all trees, including container stock or cuttings. If 90 percent survival has not been achieved, replanting with appropriate size container stock or cuttings necessary to achieve this standard will be performed. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January, 28, 2000 20 Oak woodland revegetation will be considered successful at five years if the percent cover and species diversity of the restored and/or created habitat areas are similar to percent cover and species diversity of adjacent existing habitats or impacted habitats as determined by quantitative testing of existing and restored and/or created habitat areas. 1. Cover by Exotic Species (Weeds) Weeds are typically a problem with habitat restoration, particularly at the outset of the project. As the restoration takes hold, the problems with weeds should decrease. Many local weeds have become naturalized, and therefore the tolerance for weeds should reflect what is present at the existing habitats on site. The measure for tolerance should be total cover of weed species. Although weeds are expected to be a problem, it doesn't mean they are to be accepted. Weeds should be controlled as specified in the maintenance monitoring section. 2. Sampling Techniques Two 5 -meter by 50 -meter belt transects per slope exposure will be used to monitor the development of the revegetation. The various transects will be randomly located for the fust sampling event and permanently marked to facilitate their use in subsequent years. Herbaceous, shrub, and tree vegetation layers will be sampled by a line transect in the middle of the belt transect. At each 0.5 - meter interval, the species that intercept that point will be noted according to strata. All species which occur within the belt transect will also be noted. Please refer to the California Native Plant Society vegetation sampling method for further details (Sawyer and Keller -Wolf 1995). Success criteria milestones are provided below (Table 4).

Photo Documentation In addition to the measurements specified above, several permanent stations for photo -documentation should be established in each habitat type. 4. Species Diversity and Recruitment Species diversity and recruitment are closely linked, as diversity increases with recruitment. The effect of recruitment on diversity should be to approach the level of species diversity of the reference site. Ultimately, the site should reach 80 percent of the species diversity of the reference site. Species diversity will be quantified by making a species list within the aforementioned belt transects. D. POTENTIAL REMEDIAL ACTIONS The City may terminate monitoring earlier than five years if it is recommended first by the restoration specialist in a year-end report. Likewise, if at the end of five years, any of the restored areas fail to meet the year -five standards, then the monitoring and maintenance period will be extended one full year, and a specific set of remedial measures (approved by the City) will be implemented. Only areas which fail to meet the success standards will require additional work, that is, not all of the areas originally restored. This process will continue until all year -five standards are met, or as otherwise provided in this document, the City determines that other mitigation measures are appropriate. IX. OTHER MITIGATION MEASURES A number of other measures are also included in the mitigation requirements for the project. These are described below. In conjunction with development of final plans and specifications for construction, or other activities involving significant soil disturbance, the project biologist shall map all sensitive habitats within 100 feet of the grading limits and/or fuel modification boundaries on the grading plans. Sensitive habitats include but are not limited to: scrub, woodland, and riparian habitats. Within the sensitive habitats, the following limitations shall be observed: 1) no construction access, parking, or storage of equipment or materials will be permitted within such marked areas; 2) to the maximum extent practicable, construction access points shall be limited where they are adjacent to protected habitat; 3) waste dirt or rubble will not be deposited on protected habitat; and 4) vehicle transportation routes will be confined to the narrowest practicable width in areas adjacent to marked, protected habitat during construction activities. Prior to commencementof grading activities or other activities involving significant soil disturbances, the project biologist shall attend preconstruction meetings with the applicant's construction managers to confirm grading and construction procedures as they relate to the protection of preserved habitat areas. HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 22 During grading activities and construction operations, the project biologist shall submit a monthly letter report to the City of Diamond Bar summarizing site visits, documenting adherence or violations of required habitat protection measures, and listing any necessary remedial measures. During all construction activities, the applicant shall ensure that construction equipment or vehicles are not stored within drainage areas and that there shall be no fueling, lubrication, or maintenance of construction equipment within 150 feet of applicable California Department of Fish and Game and U.S. Army Corps of Engineers jurisdictional areas. During all construction activities, the applicant shall ensure that no waste material is discharged to any drainage areas, channels, or streams. Spoil sites shall not be located within any streams or in areas where spoils could be washed into any surface water body. Prior to initiation of construction, the applicant shall located silt settling basins away from streams to prevent discolored, silt - bearing water from reaching the stream. If silt catchment basins are using during project construction, the basins shall be placed across the stream immediately downstream of the project site prior to initiation of project grading. Catchment basins shall be constructed of materials which are free from mud and silt. Upon completion of the project, all basin materials, along with the trapped sediments, shall be removed from the stream in such a manner that said removal shall not introduce sediment to the stream. Prior to catchment basin removal, basins will be surveyed for the presence of sensitive wildlife. Any sensitive wildlife present will be relocated prior to removal of basin. If the project biologist determines that turbidity/siltation levels from project -related activities constitute a threat to downstream biological resources, activities associated with the turbidity/siltation shall be halted until effective control devices are installed or abatement procedures are initiated. An erosion control plan shall be approved by the City of Diamond Bar and the California Regional Water Quality Control Board prior to initiation of grading to ensure protection of downstream water quality and prevent extensive siltation. This plan shall stabilize sediment and reduce erosion hazard, decreasing impacts to downstream aquatic resources. Prior to initiation of any construction activity, the project biologist shall survey the construction limits for the presence of occupied raptor nests and nest burrows (for burrowing owls). Occupied raptor nests/burrows shall be mapped on the construction plans by the project biologist. The project biologist will visit the nest/burrow site at the beginning of the nesting season to verify the use of the nests/burrows for that particular year. If nesting activity begins at any nest site, then the active nest/burrow(s) shall be protected until nesting activity has ended to ensure compliance with Section 3503.5 of the California Fish and Game Code. To protect any active nest/burrow sites, the following restrictions on construction are required between February I and June 30 (or until nests are no longer active as HELIX - ,,, � ter„ as z000 Biological Resource Management Plan for the Diamond Hilts ranch Property / S..A �0 / January 28, 23 determined by the project biologist): 1) clearing limits will be established a minimum of 300 feet in any direction from raptor nests/burrows; and 2) access and surveying will be allowed within 200 feet of nests/burrows. If the measures outlined in this BRMP are implemented as outlined, all impacts to Diegan coastal sage scrub, coast live oak woodland, streambed, individual California black walnuts, and other sensitive species occurring on the site will be fully mitigated. M COMPLETION OF MITIGATION A. NOTIFICATION OF COMPLETION The CDFG and ACOE shall be notified of completion ofthe mitigation effort through the submittal ofthe five-yearmonitoring report. B. ACOE AND CDFG CONFIRMATION If the project meets all success standards at the end of the five -year -monitoring period then the mitigation will be considered a success. If not, the maintenance and monitoring program will be extended one full year at a time and a specific set of remedial measures (approved by the ACOE and CDFG) will be implemented until the standards are met. This process will continue until all year -five standards are met or until the ACOE and CDFG determine that other mitigation measures are appropriate. Should he mitigation effort meet all goals prior to the end of the five -year -monitoring period, the ACOE and CDFG, at their discretion, may terminate the monitoring effort. Alternatively, a subsequent agreement may be negotiated with the ACOE and CDFG. Only areas that fail to meet the success standards will be subject to any subsequent agreement.

HELIX Biological Resource Management Plan for the Diamond Hills Ranch Property / SCA -10 / January 28, 2000 25 FEDERAL AND STATE JURISDICTIONAL DEFINITIONS APPENDIX A FEDERAL AND STATE JURISDICTIONAL DEFINITIONS I. Federal Definitions A. Wetlands and "Waters of the United States" Definitions The Army Corps of Engineers (Federal Register 1982) and the Environmental Protection Agency (Federal Register 1980) jointly define wetlands as: "Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (Environmental Laboratory, 1987). The official definition of "Waters of the United States" (Waters of the U.S.) and their limits of jurisdiction, as they may apply within the study area, are defined by the U.S. Army Corps of Engineers' Regulatory -- Program Regulations (Section 328.3, paragraphs (a)1-3 and (e), and Section 328.4, paragraphs (c) 1 and 2) as: "All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; all waters including interstate wetlands, all other waters such as interstate lakes, rivers, streams [including intermittent streams], mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate commerce including any such water, which are or could be used by interstate travelers for recreation or other purposes; or from which fish or shellfish are or could be taken and sold in interstate commerce; or which are or could be used for industries in interstate commerce; or wetlands adjacent to waters [other than waters that are themselves wetlands]." "Non -tidal waters of the United States. The limits of jurisdiction in non -tidal waters: In the absence of adjacent wetlands, the jurisdiction extends to the ordinary high water mark, or when adjacent wetlands are present, the jurisdiction extends to the limit of the adjacent wetlands." "The term ordinary high water mark means that line on the shore established by the fluctuation of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation (scouring), the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas." For purposes of delineation and jurisdictional designation, Waters of the U.S. must exhibit an ordinary high water mark or other evidence of surface flow created by hydrologic physical changes. These physical changes include the indicators used for satisfying the hydrologic criterion for wetland delineations. Wetland boundaries were determined using the three mandatory criteria (plant, soils, and hydrology) established for wetland delineations and described within the Wetlands Delineation Manual (Environmental Laboratory 1987) and subsequent regulatory guidance letters (March 6, 1992; October 7, 1991). Following is a brief discussion of the three criteria and how they were evaluated. 1. Vegetation "Hydrophytic vegetation is defined herein as the sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present" (Environmental Laboratory 1987). A-1 The wetland indicator status (obligate upland, facultative upland, facultative, facultative wetland, obligate wetland, or no indicator status) of the dominant plant species of all vegetative layers were determined. Species considered to be wetland or hydrophytic includes the classifications of facultative, facultative wetland, and obligate wetland as defined by Reed (1988)(Table Al). The percent of dominant wetland plants was calculated. The wetland vegetation criterion was considered to be met if more than 50% of the dominant plants within the area sampled were classified as a wetland species. Table Al. Definitions of Plant Indicator Categories Indicator Catezories Obligate wetland Facultative wetland Facultative Facultative upland Obligate upland Non indicator 2. Hydrology Probability of Occurring in Wetlands Occur almost exclusively in wetlands Usually found in wetlands (66-99% probability), but occasionally in uplands Equally likely to occur in wetland (34-66% probability) or non - wetland Usually occur in non -wetlands, but occasionally found in wetlands Occur almost exclusively in non -wetlands Inconclusive status "The term "wetland hydrology" encompasses all hydrologic characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season. Areas with evident characteristics of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic reducing conditions, respectively" (Environmental Laboratory, 1987). Hydrologic characteristics must indicate that the ground is saturated to within 12 inches of the surface for at least 5 percent of the growing season during a normal rainfall year (approximately 18 days for most of low-lying southern California). Hydrology criteria were evaluated based on the characteristics described in the following list. Where positive indicators of wetland hydrology were present, the limit of the Ordinary High Water Mark (OHWM) was noted and mapped. Hydrologic indicators include: • inundated soils • saturated soils within 12" of the surface • water marks • drift lines • sediment deposits • drainage patterns in wetlands (meandering water course) I:Q►A • presence of oxidized root channels surrounding living roots (oxidized rhizospheres) • water -stained leaves • plants with hydrologically induced morphological adaptations to prolonged inundation and/or saturation (e.g., aerenchyma in roots and stems, adventitious roots, and/or pneumataphores) • local soil survey data • FAC -neutral test (ratio of OBL + FACW : FACU + UPL) • in the absence of all other hydrologic indicators and in the absence of significant modifications of an areas hydrologic function, positive hydric soil characteristics are assumed to indicate positive wetland hydrology 3. Soils "A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part" (US Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) 1995). Soils must exhibit physical and/or chemical characteristics indicative of permanent or periodic saturation. Soil matrix and mottle colors were identified at each sampling point using a Munsell soil color chart (Kollmorgen 1975). Generally, an 18 -inch or deeper pit was excavated with a shovel at each sampling point, unless refusal occurred above 18 inches. Mineral soils were considered hydric if the horizon immediately below the A horizon (or 10 inches) had (1) a matrix chroma of two or less in mottled soils, or (2) a matrix chroma of one or less in unmottled soils. Soils in each area were closely examined for hydric soil indicators, including the following characteristics: • histosols • histic epipedons • sulfidic odor • aquic moisture regime • reducing conditions • gleyed or low-chroma colors • concretions • high organic content in surface layer of sandy soils • organic streaking in sandy soils • listed on local hydric soils list • listed on national hydric soils list A-3 Hydric soils are assumed to be present in plant communities that have a complete dominance of obligate or facultative wetland species. In some cases, there is only inundation during the growing season, and determination must be made by direct observation during that season, recorded hydrologic data, testimony of reliable persons and/or indication on aerial photographs. Soil series/phase was determined by examination of area soil maps provided in the soil survey for the area. B. Non -vegetated Waters of the United States The non -vegetated (non -wetland) Waters of the U.S. designation was met when an area exhibited positive indicators within the hydrologic criteria, but lacked sufficient indicators to meet the hydrophytic vegetation and/or hydric soils criteria. For purposes of delineation and jurisdictional designation, non- vegetated Waters of the U.S. must exhibit an OHWM created by periodic surface flow. The boundaries of non -vegetated Waters of the U.S. were delineated at the OHWM as described in the Section 404 regulations (33 CFR Part 328). II. State Regulations A. California Department of Fish and Game Regulations The California Department of Fish and Game (CDFG) regulates alterations or impacts to streambeds or lakes (wetlands) under Fish and Game Code 1601 for government or public utility initiated projects, and under Code 1603 for privately initiated projects. The CDFG requires a Streambed/Lake Alteration Agreement (SAA) for projects that will divert or obstruct the natural flow of water, change the bed, channel or bank of any stream, or use any material from a streambed. The SAA is a contract between the applicant and the CDFG stating what can be done in the riparian zone and stream course (California Association of Resource Conservation Districts). Intermittent streams and natural drainage channels are also regulated under Fish and Game Code 1601 and 1603 and require a SAA. Fish and Game code 1601 regulates these areas as follows: "Except as hereinafter provided, general plans sufficient to indicate the nature of a project for construction by, or on behalf of, any governmental agency, state or local, and any public utility, of any project which will divert, obstruct or change the natural flow or bed, channel or bank of any river, stream or lake designated by the department in which there is at any time an existing fish or wildlife resource or from which these resources derive benefit, or will use material from the streambeds designated by the department, shall be submitted to the department. When an existing fish or wildlife resource may be substantially adversely affected by such construction, the department shall notify the governmental agency or public utility of the existence of such fish or wildlife resource together with a description thereof and will propose reasonable modifications in the proposed construction as would allow for the protection and continuance of the fish or wildlife resource, including procedures to review the operation of such protective measures." "Agencies or public utilities proposing projects affected by this section shall not commence such.operations until the department has found that such project will not substantially adversely affect an existing fish or wildlife resource or until the _ department's proposals, or the decisions of a panel of arbitrators, have been incorporated into such projects." Projects that fall under these guidelines will require a 1601 Streambed/Lake Alteration Agreement. Fish and Game Code Section 1603 regulates these areas as follows: "It is unlawful for any person to substantially divert or obstruct the natural flow or substantially change the bed, channel or bank of any river, stream or lake designated by the department, or use any material from the streambeds, without first notifying the department of such activity, except when the department has been notified pursuant to Section 1601." Also, "It is unlawful for any person to commence any activity affected by this section until the department has found it will not substantially adversely affect an existing fish or wildlife resource or until the department's proposals, or the decisions of a panel of arbitrators, have been incorporated into A-4 such projects." Projects that fall under these guidelines will require a 1603 Streambed/Lake Alteration Agreement. B. Section 401 Certification The California Regional Water Quality Control Boards (RWQCB) require Federal Clean Water Act (CWA) Section 401 Water Quality Certification. Federal CWA Section 401 requires that every applicant for a U.S. Army Corps of Engineers CWA Section 401 permit or a Rivers and Harbors Act Section 10 permit must request State certification from the Regional Board that the proposed activity will not violate State and Federal water quality standards.

MEETING DATE: February 15, 2000 TO: Honorable Mayor and Members of the City Council FROM: Terrence L. Belanger, City Manager SUBJECT: Amendment No. 5 to a Professional Services Agreement with BonTerra Consulting regarding Environmental Services for proposed VTM 52267 (SunCal) ISSUE STATEMENT: This report requests approval of an amendment to an existing consulting services agreement with BonTerra Consulting in order to provide environmental services necessary to monitor the mitigation measures as outlined within the previously approved Vesting Tentative Tract map No. 52267. RECOMMENDATION: It is recommended that the City Council approve an amendment to the agreement between the City and BonTerra Consulting in the amount of $99,446.00. FINANCIAL STATEMENT: Costs associated with processing and development of the project are funded through developer fees paid by the project developer / applicant to the City. BACKGROUND: In December 1996, the City entered into a contract with BonTerra Consulting in the amount of $83,645.00 to prepare an Environmental Impact Report for proposed Vesting Tentative Tract Map No. 52267 (SunCal). The City Council approved a $31,508 amendment to the contract in March 1998 to augment the previously prepared environmental documentation. A second amendment in the amount of $3,950.00 was approved in August 1998 for an analysis of an additional alternative design. Vesting Tentative Tract Map No. 52267 was approved by the City Council for the development of 130 homes adjacent to Diamond Bar Boulevard in September 1998. The City Council approved a $2,810.00 contract amendment with BonTerra Consulting in November 1998 to compensate the consultants for additional work performed related to the completion of the environmental impact report. The applicant (SunCal/Diamond Hills Ranch Partnership) has requested Final Map approval and map recordation in order to obtain a vegetation clearance and grading permit from the City. Amendment No. 4, approved on January 18, 2000, incorporated a work program and budget for the City consultant to review and evaluate plan submittals, the Biological Resources Management Plan, tree replacement plan, and conduct a site survey for the presence of occupied raptor nests/ burrows and the location of any sensitive habitats within 100 feet of the construction site limits.
