Citywide City of Diamond Bar It is recommended that the Planning Commission reopen the public hearing, receive public testimony, and continue the matter to February 9, 1999. City of Diamond Bar PLANNING COMMISSION Staff Report AGENDA ITEM NUMBER: REPORT DATE: January 21, 1999 MEETING DATE: January 26, 1999 CASE/FILE NUMBER: GPA 98-1 APPLICATION REQUEST: A request to amend Objective 1.5, Strategy 1.5.3 of the General Plan Land Use Element. PROJECT LOCATION: APPLICANT: INTRODUCTION: Citywide City of Diamond Bar The City Council has requested Planning Commission review and consideration of a proposed General Plan Amendment to the Land Use Element, Objective 1.5, Strategy 1.5.3. The proposed amendment would insert text to require an election for the removal or modification of an open space deed, easement or map restriction. The Planning Commission public hearing on this matter was opened on January 12, 1999 and continued to January 26, 1999. BACKGROUND: The General Plan, adopted in 1995, includes a Vision Statement containing the following six components: • Retention of the rural/country living character. • Preservation of open space resources. • Reduction of regional traffic impacts upon local streets. • Promotion of viable commercial activity. • Provision of well maintained, attractive housing. • Creation of a nurturing community environment. GPA 98-1 Planning Commission Staff Report January 26, 1999 The General.Plan identifies the definition and preservation of open space resources as a major land use issue for the City. Several Goals, Objectives and implementation Strategies contained within the General Plan describe mechanisms for land use development and open space preservation. Implementation measures within the Land Use Element and the Resource Management Element outline the need to: ® Identify and preserve significant visual features and open space land; ® Develop a slope density formula for the preservation of open space; ® Obtain open space through acquisition, entitlement review, density transfer, clustering and other available techniques. The General Plan, Land Use Element declares within Goal 1: "Consistent with the Vision Statement, maintain a mix of land uses which enhance the quality of life of Diamond Bar residents, providing a balance of development and preservation of significant open space areas to assure both economic viability and retention of distinctive features of the community" Strategy 1. 1.6 of the Land Use Element defines the Open Space land use designation as follows: "Areas designated as Open Space (OS) provide recreational opportunities, preservation of scenic and environmental values, protection of resources (water reclamation and conservation), protection of public safety and preservation of 'animal life: This designation also includes lands which may have been restricted to open space by map restriction, deed (dedication, condition, covenant and/ or restriction), by an Open Space Easement pursuant to California Government Code (CGC), Section 51070 et seq. and Section 64499 et seq. This designation carries with it a maximum development potential of one single family unit per existing parcel, unless construction was previously restricted or prohibited on such properties by the County of Los Angeles" 2 GPA 98-1 Planning Commission Staff Report January 26, 1999 Specifically, the General Plan, Land Use Element, Objective 1.5, Strategy 1.5.3 states: "Land designated as Open Space bydeed (dedication, condition, covenant, and/or restriction), by open space easement (CGC Section 51070 et seq.) or by map restriction (explicit or previous subdivision) must comply with an established review and decision making process prior to the recision, termination, abandonment and/or removal of an open space dedication easement and/or restriction. Any decision to rescind, terminate, abandon, remove or modify a deed must be supported by findings that the decision is of significant benefit to the City. (a) Vacant land which deed is burdened by an open space dedication, condition, covenant and or restriction shall be required to be subject to the abandonment process substantially similar to that which is setforth in CGC Section 51090 et seq. (b) vacant land which is burdened by an open space easement pursuant to CGC Section 51070 et seq. shall be required to be subject to the abandonment process set forth in CGC Section 51090 et seq. (c) Vacant land which is burdened by an explicit open space designation delineated upon a map which was the result of a previous subdivision approval shall be required to be subjected to at least one public hearing before the City Council prior to any action to remove said restriction." DISCUSSION: The City Council has requested consideration of a proposed text amendment to the General Plan. The specific request is to amend Objective 1.5, Strategy 1.5.3 of the Land Use Element with the insertion of the following language: "Any decision to rescind, terminate, abandon, remove or modify a deed must be supported by findings that the decision is of significant benefit to the City and the matter must be submitted as a ballot measure to the registered voters of Diamond Bar at an election; whereas a majority of those voting must vote in the affirmative on the ballot measure." 3 GPA 98-1 Planning Commission Staff Report January 26, 1999 The General Plan identifies approximately 578 acres of land as open space and approximately 158 acres of parkland. The recent approval of the 130 home SunCal / Diamond Hills Ranch Partnership project will result in an increase in the amount of land designated as open space and parkland. SunCal will dedicate 350 acres of land to the City as open space. Thus, the amount of. open space in Diamond Bar will increase from approximately 578 acres to 928 acres. In addition the project approval will result in the dedication of 10 acres of parkland to the City for a total of 168 acres. The Environmental Impact Report for the General Plan incorporated an Open Land Survey that identified known construction restrictions for the major. vacant properties in the City. The survey identified vacant properties with the following restrictions and prohibitions: ®. The right to prohibit the construction of more than one residential building. ® The right to prohibit the construction of residential buildings. ® The right to prohibit the construction of buildings or other structures. ® Construction restrictions as a result of flood or geotechnical hazards. The General Plan Land Use Element and Map have designated the following properties as Open Space: • Approximately 37 acres generally located north of Pathfinder Road west of Brea Canyon Road, owned by the Pathfinders Homeowners Association. ® Oakridge Community Homeowners Association properties comprised of approximately 162 acres located south of Pathfinder Road, west of the 57 Freeway. ® Approximately 114 acres located within the Gateway Corporate Center located on the hillside east of Copley Drive. ® The 17 acre hillside portion of the Citrus Valley Health Partners property located adjacent to Grand Avenue, west of the . Montifino Condominium complex. ` ® Approximately 68 acres owned by D&L Properties adjacent to Grand Avenue at Summitridge Drive. ® Approximately 30 acres located adjacent to Pantera Elementary School. ® The Country Estates park and recreational facilities which contain approximately 150 acres. 4 GPA 98-1 Planning Commission Staff Report January 26, 1999 The Planning Commission discussed the proposed General Plan text amendment on January 12, 1999. The Commission requested further information to clear up several issues raised in the discussion. The staff has reviewed the proposed language and recommends consideration of the following revised text in order to clarify the matter. "A decision to rescind, terminate, abandon, remove or modify an open space deed, map restriction or OS land use designation must be preceded by both a finding -by the City Council that the decision confers a significant benefit on the City and a favorable vote of the electorate at a regular or special election." Land designated as Open Space (OS) on the General Plan Land Use Map would be captured by the revised text as well as any open space deed or map restricted property. The General Plan text description of the Open Space (OS) designation would control the use of property within that category. The referenced properties have been designated Open Space by the City of Diamond Bar since July 1995 and are all subject to map and/or deed restrictions that limit or prohibit development. Several Cities and Counties throughout the State have requirements for elections and voter approval to conclude the decision-making process for certain land uses or for development proposals within identified areas. The City of Cypress requires voter approval for zoning modifications to Public and Semi -Public (PS) zoned property. The City of Laguna Beach has recently adopted a measure requiring voter approval in order to redesignate publicly owned open space property. Certain land use decisions in Napa County require approval by the voters rather than by the Board of Supervisors. Escondido, Walnut Creek, Riverside, San Luis Obispo and Marin County have similar requirements for voter approval of certain land use decisions. CONCLUSION: The text modification is intended to further protect and preserve open space properties. The proposed text amendment to the Land Use Element of the General Plan would result in a requirement for a citywide election and voter approval to rescind, terminate, abandon, remove or modify an open space deed, easement, map restriction or land. use map designation. The City Council, elected to represent its citizens, currently has the decision- making authority in these matters. The submission of such action to the voters, sometimes referred to as "ballot box planning", will result in additional delay, cost and uncertainty for the applicant. The submission of a land use proposal to a vote of the people does, however, provide a unique opportunity for the public to directly participate in shaping the future of their City. GPA 98-1 Planning Commission Staff Report January 26, 1999 ENVIRONMENTAL ASSESSMENT: Pursuant to the provisions of the California Environmental Quality Act the City Staff has determined that the proposed text amendment to the General Plan is categorically exempt (Section 15317). No further environmental review is required. PUBLIC HEARING NOTICE: In accordance with Chapter 22.72 of the Development Code and Section 65353 of the Government Code, notification of the proposed amendment was published in the San Gabriel Valley Tribune and the Inland Valley Daily Bulletin on January 1, 1999. In addition, notice of the Planning Commission public hearing has been provided to approximately sixteen owners of open space designated property. RECOMMENDATION It is recommended that the Planning Commission reopen the public hearing, receive public testimony, discuss the proposed amendment, and adopt a resolution recommending City Council approval of GPA 98-1.

PROJECT LOCATION:. 21810 E. Cooley Drive (Lot 22, Tract No. 39679) Diamond Bar, CA 91765 PROPERTY OWNERS: Diamond Bar Business Associates c/o AEW Capital Management, LP 601 S. Figueroa, #2150 Los Angeles, CA 90017 APPLICANT: Opus West Corporation, 2030 Main Street Irvine, CA 92614 BACKGROUND: The property owner, Diamond Bar Business Associates and applicant, Opus West Corporation are requesting approval of Development Review No. 98-15 (pursuant to Code Section 22.72.020.A. and 22.72.040). The request is for approval to construction a two-story, commercial office building of approximately 56,600 square feet to be utilized for general office. The project site is located at 21810 E. Cooley Drive (Lot 22, Tract No. 39679) within a commercial business center identified as. Gateway Corporate Center. It is a vacant lot,, approximately 6.47 acres with a 139,781 square foot (3.21 acre) graded pad. The site has a storm drain easement within the western portion, outside the bui.lable pad. The project site is adjacent to Development Review 1 No. 98-13, approved by the Commission on November 24, 1998 for Allstate Insurance. Gateway Corporate center is approximately 233 acres of which approximately 143 acres are subdivided into lots -to accommodate a mix development of office -professional, light manufacturing, restaurant and retail. The Center was processed by Los Angeles County and approved in the late 19801s. This approval incorporated a unilateral contract imposing land restrictions/development standards which the City adopted on October 17, 1989. The project site has a General Plan land use designation of Professional Office (OP). Pursuant to the General Plan, this land use designation provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses. Additionally, development within the OP designation will maintain a floor area ratio (FAR) between 9.25 and 1.00. The project site is within the Commercial- Manuf acturing-Billboard Exclusion -Unilateral Contract (C-M-BEi-U/C) Zone. This zoning designation permits general office uses. Generally, the following zones surround the project site: to the north is the Open Space (OS) and C-M-BE-U/C Zones; to the south is the C-M-BE-U/C and Single Family Residence -Minimum Lot Size 8,000 Square Feet (R-1-8,000) Zones; to the east is the C-M-BE-U/C Zone; and to the west is the C-M-BE-U/C Zone. ANALYSIS: As previously stated, the 'General Plan provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses within' the OP land use designation. The FAR requirement within this designation is between 0.25 and 1.00. The proposed project, a general office use,. with an FAR of .20, complies with the General Plan. In 1990, the City established Development Review ordinance No.5. Its purpose -is to: support the .General Plan's implementation; stress quality community design standards; encourage an orderly and harmonious appearance of structures and property; assist development to be more cognizant with public concerns of aesthetics; reasonably ensure that new development does not have an adverse aesthetic, health, safety or architecturally related impact upon adjoining properties or the. City in general and preserve significant topographic features. Pursuant to the Development Review Ordinance's Section 22.72.020.A., an application for Development Review is required for any and all commercial, industrial and institutional development which involves the issuance of a building permit for construction or reconstruction of a structure. Therefore, the proposed project, a commercial development involving the issuance of a building permit requires Development Review by the Planning Commission. K In addition to complying with the City's Development Review Ordinance, the proposed project must comply with the land use restrictions imposed upon Gateway Corporate Center by the adoption of the Unilateral, Contract.

The proposed project was reviewed by Gateway Corporate Center's architectural committee. The architectural committee approved the plans. The proposed office building's exterior is referenced in the above comparison chart. The proposed architectural style, colors and materials are compatible with the requirements of Gateway Corporate Center and existing structures within the Center. A conceptual floor plan is included as Exhibit "A". The proposed use is general office, the actual tenants are not known at this time. Therefore, the actual floor plan will vary from the concep- tual floor plan. Although the building is 56,600 gross square feet, the rental or net square footage is 54,000 square. It is the 54,000 square feet that the final floor.plan will be based on. - 4 Pursuant to the adopted Development Code and the Los Angeles County Planning and Zoning Code utilized by the City until December 2, 1998, general office requires one parking space for every 250 square feet of gross floor area. Gateway Corporate Center's development standards require that a general office use provide one parking space for every 250 square feet of net floor area. Therefore, the proposed project is required to provide 216 parking spaces based on net floor area or 226 parking spaces based on gross floor area. The proposed project will provide 243 parking spaces which is adequate for general office. .On January 6, 1999, the applicant submitted a traffic impact analysis and site plan evaluation for the City's review and approval. The analysis, dated January 5, 1999 was prepared by Linscott Law and Greenspan. The study indicates that the proposed project is expected to generate 860 daily two-way trips, with 118 trips (104 inbound, 14 outbound) anticipated during the AM peak commute hour. At the PM peak commute hour, it is anticipated that 142 trips (24 inbound, and 118 outbound) will be generated. The analysis also consider future projects for Lots 12 and 15 within Gateway Corporate Center. With the proposed and future projects, it is anticipated that the intersection of Copley Drive/Golden Springs Drive will be impacted. Additionally, the level of service (LOS) of this key intersection, during the PM peak hour will go from acceptable LOS C to LOS F. However, with the implementation of the following recommended improvements, the proposed projects' impact will be mitigate and the intersection will accommodate the increased capacity: 1. Re -stripe the northbound approach on Copley Drive to provide one left -turn and dual right -turn lanes; and 2. Modify the existing traffic signal accordingly. The identified improvements, which will be conditions of approval, are expected to mitigate the impact of future and background and/or project traffic; improve LOS to and acceptable range; and mitigate the significant impact of future development (Lots 22, 12 and 15). Site access and internal circulation were evaluated in the traffic analysis. Access and internal circulation are deemed adequate. The driveway will be able to accommodate ingress and egress traffic without undue congestion. No modifications to the existing striping on Copley Drive are required to accommodate the project driveway. Curb radii have been confirmed and will accommodate cars .and small trucks. A sidewalk partially exist adjacent to the project site's property line along Copley Drive. The applicant will be required to install a five foot wide sidewalk along the remaining property frontage at Copley . Drive which does not have a sidewalk. The sidewalk is required to be installed south of the existing parkway, five feet beyond the existing curb in order to maintain consistency with the pedestrian access within Gateway Corporate Center. 0 The City has a Trip Reduction and Travel measure ordinance No,. 1 (1993). The. Ordinance pertains to a trip reduction and travel demand management that promotes alternative transportation methods and parking management programs. The Ordinance's applicability begins with non-residential development of 25,000 square feet or more. The proposed project is approximately 56,600 square feet, as such., it is required to comply with the City's Trip Reduction and Travel Demand Measures. Parking lot lighting and exterior site lighting was not submitted. The applicant is required to submit a exterior lighting plan and a parking lot lighting plan/study for the City's review and approval prior to the issuance of a building permit. .Although a flat pad exists on the site, some grading is proposed. Approximately, 4,230 cubic yards of earth will be excavated and recompacted placing fill within the building footprint and the north, south and eastern portion of the project site. Approximately, 194 cubic yards of earth will be imported, thereby creating a fill of 4,442 cubic yards. Landscaping/irrigation is proposed. The City's current code requires that 20 percent of the site area be landscaped. As referenced in the comparison chart, Gateway Corporate Center requires that 15 percent of the gross usable lot area (including front setback area but excluding all natural and graded side and rear yard slopes) be landscaped. The City's new Development Code (Section 22.04.020 F. 4., Private Agreements.) infers that if the City is a party to an agreement (i.e. Unilateral Contract) then that agreement shall be enforced in the event of a conflict between the Development Code and the agreement. Approximately 15 -percent (acceptable pursuant to Section 22.04.020 F. 4.;) of the gross usable'lot are (including front setback area but excluding all natural and graded side and rear yard slopes) will be landscaped. The applicant is required to submit a final landscape/irrigation for the City's review and approval prior to the issuance of a building permit. The landscape plan shall include plant species, size, quantity and location. Additionally, the proposed project is required to comply with the City's established Water Efficient Landscape Regulations and will be plan checked accordingly. A trash/recycle enclosure is provided, within the parking lot. The applicant is required to submit a detail of the enclosure. Signage is not a part of this applicant. Proposed signage will be reviewed at a later date. The City's Public Works Department and Building and Safety Division reviewed this project. Their recommendations are within the attached draft resolution. R ENVIRONMENTAL ASSESSMENT: The Environmental Impact Report (SCH 80121218) that reviewed the entire development of Gateway Corporate Center and which contemplated the type of use proposed by this project, required that the following traffic mitigation measures be installed. The traffic mitigation measures required by the EIR. have been installed.. Pursuant to the provisions of the California Environmental Quality Act (CEQA), the City has determined that a Negative Declaration is required. for this project. According to CEQA Section 15070, Negative Declaration No. 98-5 hask been prepared. ..

Six property owners within a 300 foot radius of the project site were notified by mail on December 30, 1998. Resolution. NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: 1. This Planning Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. The Planning Commission hereby finds that the Initial Study review and Negative Declaration No. 98-5 has been prepared by the City of Diamond Bar in compliance with .the requirements of the California Environmental Quality Act of 1970 (CEQA) and guidelines promulgated thereunder, pursuant to Section 15070. Furthermore, Negative Declaration No. 98-5 reflects the independent judgement of the City of Diamond Bar. 3. The Planning Commission hereby.specifically finds and 1 determines that, having considered the record as a whole including the findings set forth below, and c Anges and alterations which have been incorporated into M,. conditioned upon the proposed project set forthTh-the': application, there isno evidence before this Planni'n�ig! Commission that the project proposed herein will have the potential of an adverse effect on wild lite resources or the habitat upon which the wildlife depends. Based upon 'substantial evidence, this Planning commission hereby rebuts the presumption of adverse effects contained in Section 753.5 (d) of Title 14 of the California Code of Regulations. 4. Based on the findings and conclusions set forth herein, this Planning Commission hereby finds as follows: (a) The project relates to a vacant lot, approximately 6.47 acres, with a 139,781 square foot (3.21 acre) graded pad, within a commercial business center identified as Gateway Corporate Center. (b) The project site has a General Plan land use designation of Professional Office (OP). Pursuant to the General Plan, this land use designation provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses. Additionally, development within the OP designation will maintain a floor area ratio (FAR) between 0.25 and 1.00. The proposed project maintains an FAR of 0.20. (c) The project site is within the Commercial - Manufacturing -Billboard Exclusion -Unilateral Contract (C-M-BE-U/C) Zone. This zoning designation permits an general office uses as proposed. (d) Generally, the following zones surround the project site: to the north is the Open Space (OS) and C-M- -BE-U/C Zones; to the south is the C-M-BE-U/C and Single Family Residence -Minimum Lot Size 8,000 Square Feet (R-1-8,000) Zones; to the east is the C- M-BE-U/C Zone; and to the west is the C-M-BE-U/C ,Zone. , (e) The proposed Development Review is a request to construct a two-story, commercial office building of approximately 56,600 gross square feet (54,000 net square feet) to be utilized for general office. (f) The design and layout of the proposed development is consistent with the applicable elements of the City's general plan, design guidelines of the appropriate district, and any adopted architectural criteria for specialized area, such as designated historic districts, theme areas, specific plans, community plans, boulevards, or planned developments. 2 11 t4l .The proposed project provides for the eqjj�..*ishment of office -based working environment for ge4ral offices within the General Plants OP land use ' designation. Pursuant to the General Plan, the proposed project will yield a pleasant environment for those working and visiting the office facility through its exemplary design, use of materials and colors, and landscaping which will offer a variety of plant species. The building setbacks from Copley Drive is 100 feet with the parking lot setback of 27 feet. These setbacks are appropriate in relation to the scale of the proposed building with its height of two-stories/42 feet and the street right-of-ways which are 84 feet for Copley Drive. The General Plan suggests that walls be minimized and utilized only for screening. Walls are not part of the proposed project. screening for mechanical equipment is designed as part o ' f the building with a complementary material and painted to match the building. The proposed project's architectural style, construction materials and colors are consistent and compatible with the existing structures within Gateway Corporate Center and has received the Center's architectural committee's approval. Therefore, the design and layout of the proposed project is consistent with the applicable elements of the City's General Plan, design guidelines of the appropriate district, and the City adopted architectural criteria of the Unilateral Contract of Gateway Corporate Center. (g) The design and layout of the proposed development will not unreasonably interfere with the use and enjoyment of neighboring existing or future development and will not create traffic or pedestrian hazards. The proposed general office building is within the Commercial -Manufacturing -Billboard Exclusion - Unilateral Contract (C-M-BE-U/C) Zone which permits the purposed general office use. The proposed project's site is within the established Gateway Corporate Center which permits general office uses. General office uses were originally reviewed and approved for the Center. Additionally, the Center's certified Environmental Impact Report reviewed impacts related to traffic and pedestrians. As a result, the following traffic mitigation measures were required and were installed. 1. Improve that portion of the proposed bikeway along Golden Springs Drive fronting on Gateway Corporate Center; 2. Golden Springs Drive shall be widened to provide left -turn pockets at both entrance streets to the Center; and 3. Traffic signals shall be installed4,Qn",/.&G ,,., 'olden Springs Drive, at the two entrance t'li the Center. Additionally, a traffic analysis I and site plan evaluation prepared by Linscott Law and Greenspan, dated January 6, 1999, recommends-the.following improvements: 1. Re -stripe the northbound approach on Copley Drive to provide one left-turn.and dual right - turn lanes; and 2. Modify the existing traffic signal accordingly. The identified improvements, which will be conditions of approval, are expected to mitigate the impact of future and background.and/or project traffic; improve LOS to and acceptable range; and mitigate the significant impact of future development (Lots'22, 12 and 15). (h) The architectural design of the proposed development is compatible with the character of the surrounding neighborhood and will maintain the harmonious, orderly and attractive development contemplated by Chapter 22.72 of Development Review ordinance No. 5 (1990), City Design Guidelines and the City's General Plan. Gateway Corporate Center and its Unilateral Contract were originally reviewed and approved by Los Angeles County. The Unilateral Contract sets forth land restrictions/development standards. The development standards require an architectural style that is .Modern/Contemporary with materials, textures and colors that complement this style. As a result, the City, upon incorporation adopted the Unilateral Contact, thereby adopting the specified development ,standards. However, the proposed project's architectural style,. Contemporary, construction materials and colors are consistent and compatible with the Unilateral Contract and with the existing structures within Gateway Corporate Center. Furthermore the proposed project has received the Center's architectural committee's approval. The proposed architectural design is consistent with the City's Development Review ordinance in that the project: minimizes grading effect by utilizing the existing pad and preserving the slopes'which surround the project site ; maintains public health, safety and general welfare by the installed traffic mitigation measures and the issuance of City permits and inspections; and has and orderly and harmonious design and appearance of the proposed structure, the parking area.and landscaping. 4 As also referenced in Item 4 (f), the prqppsed project's design is consistent with the applicable elements of the General Plan.. Therefore, the, proposed project is compatible with the ch a aer,/.of the surrounding neighborhood and will maintain the harmonious, orderly and attractive development contemplated by the City's Development Review ordinance and General Plan. (i) The design of the proposed development will provide a desirable environment for its occupants and visiting public as well as its neighbors through good aesthetic use of materials, texture,and color that will remain aesthetically appealing and will retain a reasonably adequate level of maintenance. As referenced in the above findings, the proposed project's design is consistent with the applicable elements of the General Plan through its exemplary design, use of materials, colors and landscaping. The proposed materials of glass, aluminum, stucco and steel are low maintenance and long lasting. The varieties of texture and color add to the design's good aesthetics. Therefore, the design of the proposed development will provide a desirable environment for its occupants and Visiting public as well as its neighbors through good aesthetic use of materials, texture and color that will remain aesthetically appealing and will retain a reasonably adequate level of maintenance. (j) The proposed development will not be detrimental to public health, safety or welfare or materially injurious to the properties or improvements in the vicinity. Before the issuance of any City permits, the proposed project is required to comply with all ,conditions within the approved resolution and the Building and Safety Division, Public Works Division, Health Department and Fire Department requirements. The referenced agencies, involvement will ensure that the proposed office facility is not detrimental to the public health, safety or welfare or materially injurious to the properties or improvements in the -vicinity. 5.

Description of Project: (Describe the whole action involved, including but not limited to later phases of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheets if necessary). The application is a request to construct a two-story office buildink of approximately 56,600 square feet on a vacant lot within a corporate center identified as "Gateway Corporate Center" The proposed use for this application is general office. As this is a spec office building, hours of operation and the number of employees are not known at this time For general office, it is rewired that this project provide parkink based on the building's gross square footage As such, 226 parking spaces are require Two -hundred and forty-three larking spaces will be provided The project site is a vacant lot of approximately 6.47 gross acres. It has a previously graded buildable pad of approximately 3 21 acres The project site is part of a 255 acre business center identified as Gateway Corporate Center which was approve by Los Angeles County and competed by 1986 Gateway Corporate Center was proposed to service the eastern San Gabriel Valley's demand for professional office facilities in a location with regional access Development within the Center can generally be characterized as professional office research and development and commercial. The Center was approved with extensive attention place on compatibility with the community and providing off site improvements to respond to impacts created by the project A Master Environmental Impact (HEIR was prepared and approved by Los Angeles Regional Planning. The document identified impacts principally related to geotechnical AMR98-15.ND 1/14/99 hazards air qualitx biota archeological/paleontology, scenic quality and traffic /access.

Mandatory Findings _ of Significance A:XDPM-15.ND 1/13/99 4 PART 3 - DETERABNATION Project Number: DR 98-15 to be completed by Lead Agency On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. X I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the MITIGATION MEASURES described on an attached sheet have been added to the project. A NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have significant effect on the environment, and an ENVIRONMENTAL EVIPACT REPORT is required. I find that the proposed project MAY have a significant effect(s) on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets, if the effect is a "potentially significant impact" OR "potentially significant unless mitigated." An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project.

A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis.) 2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4. Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an affect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must described the mitigation measures and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15061(c)(3)(1)). Earlier analyses are discussed in Section SVII at the end of the checklist. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impact (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated.. A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. A:ADR98-15.ND 1/13/99 6 ENVIRONMENTAL ISSUES a.

The project site is located within the General Plan land use designation of Professional Office (OP). This land use designation provides opportunity for the establishment of office -based working environments for general professional, and administrative. offices, as well as support uses. The proposed project is for an office use with the tenant(s) not known at this time. Therefore, the proposed project is consistent with the General Plan land use designation for the project site. The project site is located within the Commercial -Manufacturing -Billboard Exclusion-Unilateral/Contract (C-M- BE-U/C) Zone. This zone allows for a variety of land uses by -right and with a Conditional Use Permit. The land uses contemplated within this classification includes but are not limited to the following: professional office, research and development, light manufacturing, medical offices and clinics, commercial retail, restaurants, hotels, physical fitness centers and government services. Other ancillary and support uses such as day care facilities, gymnasiums, dry cleaning services, and automobile rental and leasing agencies are permitted. This zoning classification encourages uses that can benefit the community in many ways including sales tax revenues and attracting an employee base with additional buying power. b. The proposed project does not conflict with applicable environmental plans or polices adopted by the City of Diamond Bar or other agencies with jurisdiction over this project. The proposed project is consistent with the .General Plan's land use designation for the project site. The proposed project has been reviewed pursuant to CEQA requirementsand found to have no significant effect on the environment. In addition, the Gateway Corporate Center Design Guidelines provide development criteria applicable to all lots and addresses building envelope, lot coverage, parcel access, and design elements that restrict building height, exterior material and landscape pallet. Furthermore, the Gateway Corporate Center architectural committee conducts review of all such projects and approved this project. c. The proposed project is an office land use which is consistent with the General Plan, Zoning, the Gateway Corporate Center Design guidelines and the existing uses within the Center. Therefore, the proposed project is compatible with existing land uses in the vicinity. d. There are no agricultural resources or operations in the vicinity of the project area. e. Gateway Corporate Center is a professional/retail center that provides no existing residential development or opportunities for residential development. The proposed project is consistent with the character of the surrounding development and therefore A:\DPA-15.ND 1113/99 25 will not disrupt or divide the physical arrangement of an established community including a low-income or minority community. 2. POPULATION AND HOUSING a. The nature of Gateway Corporate Center lends itself to attracting businesses in need of regionally accessible transportation opportunities, affordable lease rates and an educated employee base. The proposed tenants may possess employees who reside outside of the area. Existing employees will take one of the following actions: commute from outside the area; relocate to this area; or find different employment. It is assumed that some of the replacement personnel will be from this area. If not from this area, these employees will exercise on of the aforementioned actions. These factors were contemplated when the application to develop Gateway Corporate Center was approved by Los Angeles County and were found not to be in conflict with the regional housing .projects for the area. The Center was found to provide consumers for the expanding housing opportunities present in the central San Gabriel Valley at the time of review. Presently, these conditions persist and the proposed project is consistent with regional and local housing projections. Additionally, the Center does not provide existing residential development or opportunities for residential development. Therefore, the proposed project will not displace substantial numbers of people, thereby necessitating the construction of replacement housing elsewhere. b. The proposed project is located in an area with existing commercial development and existing infrastructure that can accommodate the proposed project and contemplated development as reviewed within Gateway Corporate Center's approved EIR. Therefore, it is not anticipated that this project will induce substantial growth either directly or indirectly. c. The proposed project site is a vacant, graded lot with a buildable pad, zoned for commercial -manufacturing development, consistent with the policies presented in the General Plan. Additionally, housing was not contemplated in Gateway Corporate Center's original approval. Therefore, the proposed project does not displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere. 3. GEOLOGICAL PROBLEMS a. No portion of the City has been identified as in an Alquist-Priolo Special Studies Zone. The closest fault is the Diamond Bar Fault, which is described as a "small inactive local fault". Historically, there is no record of any earthquake with an epicenter in Diamond Bar of its Sphere of Influence, and no significant movement has ever been recorded for the Diamond Bar fault. The Whittier -Elsinore fault lies approximately four miles from the project site and has been active in historic times. Three faults with the greatest potential for activity are located in excess of 20 miles A:\DR98-15.ND 1/13/99 26 from the proposed project. Therefore, likelihood of fault rupture is limited. b. The proposed project lies within Zone 1, or Relative Ground Response Low (RGRl). Under current building and engineering codes which consider ground shaking, any impacts from seismic ground shaking may be considered less than significant. c. The closest reservoir is the Ambushers Reservoir, approximately six miles form the project site, in a different drainage basin. If seiche occurs, it will not affect the project site. Additionally, the project is not located near any volcanic mountain regions. There are no large bodies of water in close proximity to the project site. d. The proposed project site does not lie within a potential liquefaction zone. Additionally, the nature of the underlying material on the project site, the lack of ground water and the existing and proposed drainage conveyance devices within Gateway Corporate Center further diminish occurrences of liquefaction. e. Pursuant to the project's soils report, all slopes impacting the subject site are considered to be grossly and surficial stable. The slopes constructed during mass grading operations were built at a slope ration no greater than 2:1 (horizontal to vertical) and appear to be in accordance with previous project plans and specifications. These slopes appear to possess a safety factor of 1.50 or greater for gross stability. However, to minimize future erosion, the slope landscaping shall consist of a suitable proportion of deep rooted slope plantings classified as being drought resistant. Additionally, weather conditions may require additional erosion control measures such as matting, netting and plastic sheeting. f. The proposed project site is graded with a buildable pad created in conjunction with the development of Gateway Corporate Center. Pursuant to the project's soils report, Subsidence should be 0.1 feet due to earthwork operations. g. Pursuant to the project's soils report, the project site does contain expansive soil (sandy silt and shale). However, the proposed structures will be safe from excessive settlements by meeting the following requirements of. the City's Building Code; the City's Grading Ordinance; site inspections during grading and construction activities; "Specifications for Compaction Fill Operations" with in the project's soils report; deepened foundation into the underlying bedrock; and removing all disturbed soils prior to placement of any additional fill or pavement. h. Pursuant to the project's soils report, there are no significant or unique geologic of physical characteristics found on the project site. AADR98-15.ND 1/13/99 27 4. WATER a. Development of the project site will reduce pervious surfaces thereby increasing surface runoff. Runoff will be directed from on-site drainage devices into off-site drainage devices designed to accommodate runoff from the project site. The impacts associated from the increased runoff are expected to be insignificant. b. The project site is not located within a flood hazard area and adequate drainage devices have been incorporated into the drainage plan Gateway Corporate Center, as well as the proposed project. c., d., e. There is no body of surface water on the project site or the vicinity of the project. Therefore, no impacts related to surface water features, quality or flow will affect the project site. f. The proposed project will not impact the quantity of groundwater but will have an insignificant impact on the recharge of groundwater because of the reduction in pervious surfaces. g., h. The proposed project will not effect the direction or rate of flow of groundwater or groundwater quality due to conditions described above (a. through f.). i. The proposed project will not cause a significant reduction in groundwater supplies or the availability of groundwater for public water supplies. j. The proposed project is not a housing project. Nor is it within the 100 -year flood hazard area as mapped on the Federal flood Hazard Boundary or Flood Insurance Rate Map. As a result, structures will not impede or redirect flood flows. 5. AIR QUALITY a. Air quality will be affected during grading operation, however, it is not expected to be significant with procedures that will be implement to reduce air emissions. Additionally, such emissions are not expected to exceed those listed within the SCAQMD Air Quality Handbook. b. There are no known sensitive receptors within one-half mile of the project site. Therefore, any impacts to sensitive receptors will be insignificant. c. The proposed project's affect on air quality will be during grading operations only. Therefore, the affect will be temporary and will not resulting a considerable, cumulative net increase of any pollutant for which the project region is non -attainment under applicable federal or state ambient air quality standard. A:XDR98-15.ND 1/13/99 28 d. During the grading phase of the proposed project, diesel fuel odor may be emitted, however, based on the scope of the proposed grading operation the impact is not expected to be significant. 6. TRANSPORTATION/CIRCULATION a. The applicant submitted a traffic impact analysis and site plan evaluation for the City's review and approval. The analysis, dated January 5, 1999 was performed by Linscott Law and Greenspan. The study indicates that the proposed project is expected to generate 860 daily two-way trips, with 118 trips (104 inbound, 14 outbound) anticipated during the AM peal commute hour. At the PM peak commute hour, it is anticipated that 142 trips (24 inbound, and 118 outbound) will be generated. The analysis indicated that this proposed project along with proposed office building projects for Lots 12 and 15 within Gateway Corporate Center will have a significant impact at the Copley Drive/Golden Springs Drive intersection. Additionally, the level of service of this key intersection degrades during the PM peak hour from acceptable LOS C to LOS F with traffic of the proposed project and the proposed project for Lots 12 and 15. However, implementation of recommended improvements will mitigate the impact of the proposed projects. For the intersection of Copley Drive/Golden Springs Drive, the analysis recommends changing the intersection's geometry to increase capacity. The recommended changes/improvements. are as follows: re -stripe the northbound approach on Copley Drive to provide one left -turn and dual right -turn lanes. Modify the existing traffic signal accordingly. The identified improvements are expected to: mitigate the impact of future backgound and/or project traffic; improve Levels of Service to an acceptable range; and mitigate the significant impact of the development of all three lots (Lots 12, 15 and 22). As a condition of approval for the proposed project, the applicant shall be required to pay their fair share of the improvements. b. The proposed project is compatible with the established land uses .within Gateway Corporate Center and land uses identified within the General Plan and Zoning Code. Hazards identified within the traffic, report will be mitigated and instituted as conditions of approval. c. Site access and internal circulation were evaluation in the traffic analysis. Access was deemed adequate. Additionally, based on the anticipated project traffic volume, the driveways will be able to accommodate ingress and egress traffic without undue congestion. No modifications to the existing striping on Bridge Gate Drive and Copley Drive, respectively, are required to accommodate the project driveways. d. The proposed office building is approximately 56,000 square feet. Pursuant to the 29 A:1DR98-15.ND 1/13/94 City's Development Code and Gateway Corporate Center's development standards, one parking is required for each 250 square feet of gross floor area of general office use. Therefore, 226 parking spaces are required. However, the project site will provide 243 parking spaces. Therefore, the provided number of parking spaces exceeds the minimum parking requirement, thereby providing adequate parking on- site. e. As referenced above in Item a., the level of service standard will be mitigate through the recommended improvement which will be a condition of approval for the proposed project. f. The proposed project's design is consistent with the General Plan's goals, objectives and strategies supporting circulation and transportation. g. No rail, waterborne, or air traffic facilities or operations are in the vicinity of the proposed project. Therefore, the project will not impact these facilities or operations. 7. BIOLOGICAL RESOURCES a, -e. The project site is a vacant, graded site with a buildable pad area that does not contain locally designated natural communities or wetlands, In the absence of these conditions, a .determination has been made that the site is incapable of supporting endangered, threatened or rare species. The site currently supports non-native grasses, various types of rodents and unlisted migrating animal species such as coyotes, deer and domestic species. S. ENERGY a.,b. The proposed project will be required to comply with the UBC design and construction standards, thereby conforming to the City's energy conservation standards. c. The proposed project site is not within an area identified as possessing mineral resources of regional value. Therefore, it is not anticipated that the proposed project will result in the loss of availability of mineral resources that would be of future value to the region and residents of the State. 9. HAZARDS a. The proposed project will likely utilize hazardous materials, such as oil, diesel fuel, etc. during the construction phase. It is anticipated that these materials utilized during the construction phase will generated less than significant impacts. 30 AADR98-15.ND 1/13/99 b. The proposed project will not interfere with the City's emergency response plan or evacuation plan. c. The project site is located one-half mile plus an existing school. There are no schools proposed closer than one-half mile from the project site. Therefore, the proposed project or its development will not emit hazardous emissions or handle hazardous or actively hazardous materials, substances or waste within one-quarter mile of an existing or proposed school. d. The project site is not located on a site which is included on a list Iof hazardous materials site compiled pursuant to Government Code §65962.5, and as a result will not create a significant hazard to the public or the environment. e. The proposed project is in an urbanized area and not adjacent to areas where the possibility for wildland fires exist. Therefore, the proposed project will not expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. 10. NOISE . a.,b. The project site is located within an area impacted by noise generated by the SR 57 and SR 60 Freeways and Golden Springs Drive. The proposed project's development will generate noise impacts but not to a level that surpasses existing sound levels. With the completion of development, noise levels related to construction will cease. Typically, and office use does not generate excessive goundborne vibration or groundborne noise levels. Therefore, the proposed project is not expected to expose persons or generate significant noise levels in excess of standards established in the City's General Plan, noise standards, or applicable standards of other agencies; or expose persons to or generate excessive groundbome vibration or groundborne noise levels. 11. PUBLIC SERVICES a., b. The proposed project will receive fire protection and police protection services from the .Los Angeles County Fire and Sheriff Departments. Currently, these agencies provide service to Gateway Corporate Center. It is anticipated that the proposed project will not require the development of new or expanded facilities or services. c. The proposed project is located within the Walnut Valley School District. The District is in need of permanent facilities. It is not anticipated that the proposed office project will create a significant demand to the District. However, the project is required to pay school fees as part of the development fees paid to the City. 31 AADR98-15.ND 1/I3/99 d. The project will create impacts to the City's streets and sewage systems. However, these impacts were identified and mitigated as part of Gateway Corporate Center's development. e. No other specific governmental services have been identified that may be impacted by the proposed project. 12. UTILITIES AND SERVICE SYSTEMS a. -g. The development of the proposed office project will not result in the need for new systems or supplies or substantial alterations to the following: power or natural gas; communication systems; local or regional water treatment or distribution facilities; sewer systems; storm drainage systems, solid waste disposal systems, 13. AESTHETICS a. -c. The proposed project will be developed in compliance with the Design Guidelines of Gateway Corporate Center and the City's Development Review Ordinance and Design Guideline standards. As a result, the proposed project will be consistent with the existing development within the Center and surrounding area by utilizing good architectural design and features, as well as compatible and pleasing colors and materials. The only source of light and glare may emanate from the sunlight reflected on windows and the on-site lighting. However, on-site lighting will be shielded and installed in a manner that will not reflect light or glare on to neighboring properties, Copley Drive and/or Golden Springs Drive. Furthermore, the project site is not located with as adjacent to a scenic vista, historic buildings and/or a state scenic highway. The project site is previously graded with a buildable pad. It does not contain natural resources such as tree, native vegetation or rock outcroppings. 14. CULTURAL RESOURCES a. There are no paleontological sites identified within the City and the site has sustained extensive grading as part of the Center's development. Therefore, it is not anticipated that the site's development will disturb paleontological resources. b. There are no archaeological sites identified within the City and the site has sustained extensive grading as part of the Center's development. Therefore, it is not anticipated that the site's development will disturb paleontological resources. c. No historical sites have been identified within the vicinity of the project site and none are expected. Therefore, development of the proposed project will not affect historical resources. AADR96.15.ND 1/13/99 32 d., e. No unique ethnic cultural values, religious or sacred uses are located within a quarter mile of the project site. Therefore, the proposed project will not have the potential to create adverse impacts on said resources. 15. RECREATION a., b. Office projects of this type are not generally associated with creating adverse impacts on parks or other recreation opportunities. Employees will generally be from outside the City and will primarily use those facilities where they live. As such, it is not anticipated that the proposed project will increase the demand for neighborhood or regional parks or other recreational facilities or affect existing recreational opportunities to the extent that deterioration of such facilities would occur; nor that. the expansion of such facilities would occur, thereby causing an adverse physical effect on the environment. 33 AADR98-15.ND 1/13/99 0 0 U 0 0z ,D z W u I ooh "B 0 0 c) OQ O C) C) C> O C) c, C) -L lc� pL 00 r4 rq00 6i 0 6b -6 -6 0 WO u 0 0 0 7:1 0 V 43 0 r4 z W u I z z d d a a tL P.

PROJECT LOCATION: 1550 Valley Vista Drive (Lot 12, Tract No. 39679) Diamond Bar, CA 91765 PROPERTY OWNERS: Diamond Bar Business Associates C/o AEW Capital Management, LP 601 S. Figueroa, #2150 Los Angeles, CA 90017 APPLICANT: Opus West Corporation, 2030 Main Street Irvine, CA 92614 BACKGROUND: The property- owner, Diamond Bar Business Associates and applicant, Opus West Corporation are requesting approval of Development Review No. 98-15 (pursuant to Code Section 22.72.020.A. and 22.72.040). The request is for approval to construction a two-story,, commercial office building of approximately 39,0.00 gross square feet to be utilized for general office. The project site is, located at 1550 Valley Vista Drive (Lot 12, Tract No. 39679) where Valley Vista Drive meets Bridge Gate Drive, within a commercial business, center identified as, Gateway Corporate Center. It is a "horse shoe" shaped, vacant lot, approximately 2,48 acres with a 94,140 square foot (2..16 acre) graded pad. The project site is adjacent to Development Review No. 98-5 (Lot 11), 1 approved by the Commission on April 28,.1998 for St. Jude medical offices. Gateway Corporate Center is approximately 233 acres of which approximately 143 acres are subdivided into lots -to accommodate a mix development of office -professional, light manufacturing, restaurant and retail. The Center was processed by Los Angeles County and approved in the late 19801s. This approval incorporated a unilateral contract imposing land restrictions/development standards which the City adopted on October 17, 1989. The project site has a General Plan land use designation of Professional Office (OP). Pursuant to the General Plan, this land use designation provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses. Additionally, development'within the OP designation will maintain a floor area ratio (FAR) between 0.25 and 1.00. The project site is within the Commercial - Manufacturing -Billboard Exclusion -Unilateral Contract (C-M-BE-U/C) Zone. this zoning designation permits general office uses. Generally, the following zones and use surround the project site: to the north is the C-M-BE-U/C Zones; to the south is the Single Family Residence -Minimum Lot Size 8,000 Square Feet (R-1-8,000) Zone; to the east is the C-M-BE-U/C and the R-1=8,000 Zones; and to the west is the SR.57 (Orange Freeway). ANALYSIS: As previously stated, the General Plan provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses within the OP land use designation. The FAR requirement within this designation is between 0.25 and 1.00. The proposed project, a general office use, with an FAR of 0.36, complies with the General Plan. In 1990, the City established Development Review ordinance No.5 Its purpose is to: support the General Plan's implementation; : stress quality community design standards; encourage an orderly and harmonious appearance of structures and property; assist development to be more cognizant with public concerns of aesthetics; reasonably ensure that new development does not have an adverse aesthetic, health, safety or architecturally related impact upon adjoining properties or the City in general and preserve significant topographic features. Pursuant to the Development Review Ordinance's Section 22.72.020.A., an application for Development Review is required for any and all commercial, industrial and institutional development which involves the issuance of a building permit for construction or reconstruction of a structure. Therefore, the proposed project, a commercial development involving the issuance of a building permit requires Development Review by the Planning Commission. K In addition to complying with the Cityfs Development Review ordinance, the proposed project must comply with the land use restrictions imposed upon Gateway Corporate Center by the adoption of the Unilateral Contract. The following is a comparative between the Unilateral Contract's development standards and the proposed project's development standards. UNILATERAL CONTRACT'S DEVELOPMENT PROPOSED PROJECT'S STANDARDS DEVELOPMENT STANDARDS Lot 12 Lot 12 Setbacks: Minimum Setbacks: North property line - 10 ft North property line - building from the property, line for setback - 68 ft.; parking building; and 5 ft. from setback from property line - 5 property line for parking; ft; East property line -toe of slope sets the bounday for East property line — building development, approximately 45 setback - 120 ft.; parking ft.; setback - 45 ft; West property line - 25 feet West property line - building for building and parking from setback - 90 ft.; parking property line; setback - 25 ft; South property line - the toe South property line - building of slope provides boundary for setback - 95 ft.; parking - development, varying from varying 25 to 45 ft. with toe approximately 20 ft. to 45 ft.; of slope providing boundary for development; Building Height: Building Heictht: Three stories or 55.ft, Two stories/32 ft. whichever is less. 3 Parking: Parking: General offices - minimum one Parking required calculated at space for each 250 square feet minimum one space for each 250 of net floor area; square feet of net floor area - 149 parking spaces; provided.- 153 parking spaces; if overhead doors are not needed - 160 parking spaces will be provided; Parking arranged in a geometric Parking arranged in a geometric pattern; pattern; 3 ft. wide by 4 -ft. long curbed 5 ft. wide by 18 ft.

Landscaping: Landscaping: 15% of the gross usable lot 15% of the gross usable lot area (including front setback area (including front setback area but excluding all.natural area but excluding all natural and graded side and rear yard graded sides and rear yard slopes). slopes): Architecture: Architecture: Contemporary with simple Contemporary, simple in form building masses simple in form with strong geometric lines. and of strong geometry. Building Materials: Building Materials; Contemporary, utilizing glass, Glazing - blue/green reflective brick, non -pattern tile, metal glass, accent colors on 'tilt -up panels, "tilt -up", "poured -in- concrete wall - dark gray, place" or "precast concrete" medium gray and light gray. with a natural finish (sandblasted or textured), and uniform in'color, concrete block (textured, split face, or sandblasted), and/or glass block. Roofs Generally flat, with -minimum slope for adequate drainage; may include simple gable or shed forms; and Roof mounted equipment - hidden behind roof parapet, not to be visible from surrounding streets, driveways, or adjacent buildings on a horizontal sight line; or screen, constructed using materials complementary, to building, integrated with architectural design. Generally flat; Roof mounted equipment - hidden by screen, constructed from corrugated metal, painted to match building. The proposed project was reviewed by Gateway Corporate Center's architectural committee. The architectural committee approved the plans. The proposed office building's exterior is referenced in the above comparison chart. The proposed architectural style, colors and materials are compatible with the requirements of Gateway Corporate Center and existing structures within the Center. A conceptual floor plan is included as Exhibit "A". The proposed use is general office, the actual tenants are not known at this time. Therefore, the actual floor plan will vary from the concep- tual floor plan. Although the building is 39,000 gross square feet, the rental or net square footage is 37,350 square. It is the ,37,350 square feet that the final floor plan will -be based on. Pursuant to the adopted Development Code and the Los Angeles County ,Planning and Zoning Code utilized by the City until December 2, 1998, general office requires one parking space for every 250 square feet of gross floor area. Gateway Corporate Center's development standards require that a general office use provide one parking space for every 250 square feet of net floor area.. Therefore, the proposed project is required to provide 149 parking spaces based on net floor area or 156 parking spaces based on gross floor area. The proposed project will provide 153 parking spaces and 7 additional parking spaces if overhead doors are not needed, thereby providing a total of 160 parking spaces which is adequate for general office. On January . 6, 1999, the applicant submitted a traffic impact analysis and site plan evaluation for the City's review and approval. The analysis, dated January 5, 1999 was prepared by Linscott Law and Greenspan. The study indicates that the proposed project is expected to generate 640 daily two-way trips, with 89 trips (78 inbound, 11 outbound) anticipated during the AM peak commute hour. At the PM peak commute hour, it is anticipated that 123 trips (21 inbound, 102 outbound) will be generated. The analysis also consider future projects for Lots 22 (DR 98-15) and R 15 within Gateway Corporate Center. With the proposed and future projects, it is anticipated that the intersection of Copley Drive/Golden Springs Drive will be impacted. Additionally, the level of service (LOS) of this key intersection, during the PM peak hour will go from acceptable LOS C to LOS F. However, with the implementation of the following recommended improvements, the proposed projects' impact will be mitigate and the intersection will accommodate the increased capacity: .1. Re -stripe the northbound approach on Copley Drive to provide one left -turn and dual right -turn lanes; and 2. Modify the existing traffic signal accordingly. The identified improvements, which will be conditions of approval, are expected to mitigate the impact of future and background and/or project traffic; improve LOS to and acceptable range; and mitigate the significant impact,of future development (Lots 22, 12 and 15). Site access and internal circulation were evaluated in the traffic analysis. Access is deemed adequate. The driveway will be able to accommodate ingress' and egress traffic without undue congestion. No modifications to the existing striping on Valley Vista Drive/Bridge Gate Drive are required to accommodate the project driveway. On-site circulation is adequate. Curb radii have been confirmed and will accommodate cars and small trucks. A small portion of sidewalk exists adjacent to the project site's property line along Valley Vista Drive. However, the site's remaining frontage along Valley Vista and Bridge Gate Drives does not have sidewalk. Where sidewalk does not exist along the site's frontage, the applicant will be required to install a five foot wide sidewalk. The sidewalk is required to be installed south of the existing parkway, five feet beyond the existing curb in order to maintain consistency with the pedestrian access within Gateway corporate Center. The City has a'Trip Reduction and Travel Measure Ordinance No. 1 (1993). The Ordinance pertains to a trip reduction and travel demand management that promotes alternative transportation methods and parking management programs. The Ordinance's applicability begins with non-residential development of 25,000 square feet or more. The proposed project is approximately 37,350 square feet, as such, it is required to comply with -the City's Trip Reduction and Travel Demand Measures. Parking lot lighting and exterior site lighting was not submitted. The applicant is required to submit a exterior lighting plan and a parking lot lighting plan/study for the City's review and approval Prior -to the issuance of a building permit. Although a flat pad exists on the site, some grading is proposed. Approximately, 2,458 cubic yards of earth will be utilized for fill with 88 cubic yards of earth imported. The fill areas are mainly 0 located within the building footprint and within the northern, southern and western portion of the project site. Landscaping/irrigation is proposed. The City's current code requires that 20 percent of the site area be - landscaped. As referenced in the comparison chart, Gateway Corporate Center requires that 15 percent of the gross usable lot area (including front setback area but excluding all natural and graded side and rear yard slopes). be landscaped. The City's new Development Code (Section 22.04.020 F. 4., Private Agreements.) infers that if the City is a party to an agreement (i. e. Unilateral Contract) then that agreement shall be enforced in the event of a conflict between the'Development Code and the.agreementi Approximately 15 percent (acceptable pursuant to Section 22.04.020 F. 4.,) of the gross usable lot are (including front, setback area but excluding all natutal and graded side and rear yard slopes) will be landscaped. The applicant is required to submit a final landscape/ irrigation for the City's review and approval prior to the issuance of a building permit. The landscape plan shall include plant species, size, quantity and location. Additionally, the proposed project is required to comply with the City's established Water Efficient Landscape Regulations and will be plan checked accordingly. A trash/recycle enclosure is provided, within the parking lot. The applicant is required to submit a detail of the enclosure. - Signage is not a part of this applicant. Proposed signage will be reviewed at a later date. The City's Public Works Department and Building and Safety Division reviewed this project. Their recommendations are within the attached draft resolution. ENVIRONMENTAL ASSESSMENT: The Environmental Impact Report (SCH 80121218) that reviewed the entire development of Gateway Corporate Center and which contemplated' the type of use proposed by this project, required that the following traffic mitigation measures be installed. The traffic mitigation measures required by the EIR have been installed. Pursuant to the provisions of the California Environmental Quality Act (CEQA), the City has determined that a Negative Declaration is required for this project. According to CEQA Section 15070, Negative Declaration No. 98-6 has been prepared. , NOTICE OF PUBLIC HEARING: Notice for this project was published in the Inland Valley Bulletin and the San Gabriel Valley Tribune on January 4, 1999. Public hearing notices were mailed to approximately 7 property owners within a 300 foot radius of the project site on December 30, 1998. F& RECOMMENDATIONS: Staff recommends that the Planning Commission approve Development Review No. 98-16, Findings of Fact and conditions of approval as' listed within the attached resolution. REQUIRED DEVELOPMENT REVIEW FINDINGS: 1.

NOW THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: 1. This Planning Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. The Planning Commission hereby finds that the Initial Study review and Negative Declaration No. 98-6 has been prepared by the City of Diamond Bar in compliance with the requirements of the California Environmental Quality Act of 1970 (CEQA) and guidelines promulgated thereunder, pursuant to Section 15070. Furthermore, Negative Declaration No. 98-6 reflects the independent judgement of the City of Diamond Bar. .3. The Planning Commission hereby specifically fis and determines that, having considered the record :�j) orle g including,the findings set forth below, and ch�"' ? alterations which have been incorporated into and conditioned upon the proposed project set forth in the application, there is no evidence before this Planning Commission that the project proposed herein will have the potential of an adverse effect on wild -life resources or the habitat upon which the wildlife depends. Based upon substantial evidence, this.Planning Commission hereby rebuts the presumption of adverse effects contained in .Section 753.5 (d) of Title 14 of the California Code of 'Regulations. 4. Based on the findings and conclusions set forth herein, this Planning Commission hereby finds as follows*: (a) The project relates to a "horse shoe" shaped vacant lot, approximately 2.48 acres with a 94,140 square foot (2.16 acre) graded pad, within a commercial business center identified as Gateway Corporate Center. (b) The project site has a General Plan land use designation of Professional Office (OP). Pursuant to the General Plan, this land use designation provides for the establishment of office -based working environments for general, professional, and administrative offices, as well as support uses. Additionally, development within the OP designation will maintain a floor area ratio (FAR) between 0.25 and 1.00. The proposed project maintains an FAR of 0.36. (c) The project site is within the Commercial - Manufacturing -Billboard Exclusion -Unilateral Contract (C-M-BE-U/C) Zone. This zoning designation permits an general office uses as proposed. (d) -Generally, the following zones use surround the project site: to the north is the C-M-BE-U/C Zones; to the south is the Single Family Residence -minimum Lot Size 8,000 Square Feet (R-1-8,000) Zone; to the .east is the C-M-BE-U/C and the R-1-8,000 Zones; and to the west is the SR 57 (Orange Freeway). (e) The proposed Development Review is a request to construct a two-story, commercial office building of approximately 39,000 gross square feet (37,350 net square feet) to be utilized for general office. (f) The design and layout of the proposed development is consistent with the applicable elements of the City's general plan, design guidelines of the appropriate district, and any adopted architectural criteria for specialized area, such as designated historic districts, theme areas, specific plans, community plans, boulevards, or planned developments. ig The proposed project provides for the estabkishment of office -based working environment for gee, G, offices within the General Plan's OP land %U47 designation. Pursuant to the General Pla- proposed project will yield a pleasant environmen for those working and visiting the office facility through its exemplary design, use of materials and colors, and landscaping which will offer a variety of plant species. The building setback from Valley Vista Drive is 90 feet with a parking lot setback of 25 feet. The building setback from Bridge Gate Drive is 120 feet with a parking lot setback of 45 feet. These setbacks are appropriate in relation to the scale of the proposed building with its height .of two-stories/32 feet and the street right-of-ways of 70 feet for'Valley Vista and Bridge Gate Drives. The General Plan suggests that walls be minimized And utilized only for screening. Walls are not part of the proposed project. Screening for mechanical equipment is designed as part of the building with a complementary material and painted to match the building. The proposed project's architectural style, construction materials and colors are consistent and compatible with the existing structures within Gateway Corporate Center and has received the Center's architectural committee's approval. Therefore, the design and layout of the proposed project is consistent with the applicable elements of the City's General Plan, design guidelines of the appropriate district, and the City adopted architectural criteria of the Unilateral Contract of Gateway Corporate Center. (g) The design and layout of the proposed development will not unreasonably interfere with the use and enjoyment of neighboring existing or future development and will not create traffic or pedestrian hazards. The proposed general office building is within the Commerdial-Manufacturing-Billboard Exclusion - Unilateral Contract (C-M-Bt-U/C) Zone which permits the purposed general office use. The proposed project's site is within the established Gateway Corporate Center which permits general office uses. General office uses were originally reviewed and approved for the Center. Additionally, the Center's certified Environmental Impact Report reviewed impacts related to traffic and pedestrians. As a result, the following traffic mitigation measures were required and were installed. 1. Improve that portion of the proposed bikeway along Golden Springs Drive fronting on Gateway Corporate Center; 3 2. Golden Springs Drive shall be widened to provide left -turn pockets at both entrance streets to the Center;*and 3. Traffic signals shall be installed on Golden Springs Drive, at the two entrance drives to the Center. Additionally, a traffic analysis and site plan evaluation prepared by.Lin'scott Law and Greenspan, dated January 6, 1999, recommends the following improvements: 1. Re -stripe the northbound approach on Copley Drive to.provide one left --!turn and dual right - turn lanes; and 2. Modify the existing traffic signal accordingly. The.identified improvements, which will be conditions of approval, are expected to mitigate the impact of future and background and/or project traffic; improve LOS to and acceptable range; and mitigate the impact of future development (Lots 22, 12 and 15). (h) The architectural design of the proposed development is compatible with the character of the surrounding neighborhood and will maintain the harmonious, orderly and attractive development contemplated by Chapter 22.72 of Development Review Ordinance No. 5 (1990), City Design Guidelines and the City's General Plan. Gateway Corporate Center and its Unilateral Contract were originally reviewed and approved by Los Angeles County. The Unilateral Contract sets forth land restrictions/development standards. The development standards require an architectural style that is Moddrn/Contempbrary with materials, textures and colors that complement this style. As a result, the City, upon incorporation adopted the Unilateral Contact, thereby adopting the specified development standards. However, the proposed project's architectural style, Contemporary, construction materials and colors are Consistent and compatible with the Unilateral'Contract and with the existing structures within Gateway Corporate Center. Furthermore the proposed project has received the Center's architectural committee's approval. The proposed architectural design is consistent with the City's Development Review Ordinance in that the project: minimizes grading effect by utilizing the existing pad and preserving the slopes which surround the project site ; maintains public health, safety and general welfare by the installed traffic 4 mitigation measures and the issuance of C1 permits and inspections; and has and orderly and pious design and appearance of the proposed stru e parking area and landscaping. As also referenced in Item 4 (f),.the proposed project's design is consistent with the applicable elements of the General Plan. Therefore, the proposed project is compatible with the character of the surrounding neighborhood and will maintain the harmonious, orderly and attractive development contemplated by the City's Development Review ordinance and General Plan. The design of the proposed development will provide a desirable environment for its occupants and visiting public as well as its neighbors through good aesthetic use of materials, texture, and color that will remain aesthetically appealing and will retain,a reasonably adequate level of maintenance. As referenced in the above findings, the proposed project's design is consistent with the applicable elements of the General Plan through its exemplary design, use of materials, colors and landscaping. The proposed materials of glass and concrete tilt -up walls are low maintenance and long lasting. The . varieties of texture and color add to the design's good aesthetics. Therefore, the design of the proposed development will provide a desirable environment for its occupants and visiting public as well as its neighbors through good aesthetic use of materials, texture and color that will remain aesthetically appealing and will retain a reasonably adequate level of maintenance. (j) The proposed development will not be detrimental to public health, safety or welfare or materially injurious to the properties or improvements in the vicinity. Before the issuance of any city permits, the proposed project is required to comply with all conditions within the approved resolution and the Building and Safety Division, Public Works Division, Health Department and Fire Department requirements. The referenced agencies' involvement will ensure that the proposed office facility is not detrimental to the public health, safety or welfare or material- ly injurious to the properties or improvements in the vicinity. 5.

Attach additional sheets if necessary). The application is a request to construct a two-story office building of approximately 39,600 square feet on a vacant lot within a corporate center identified as "Gateway Corporate Center" The proposed use for this application is general office. As this is a spec office building, hours of operation and the number of employees are not known at this time For general office, it is required that this project provide parking based on the building's gross square footage As such 156 parking spaces are require One hundred and fifty three parking apaces will be provided The project site is a "horse shoe" shaped vacant lot of approximately 2.48 gross acres. It has a previously graded buildable pad of approximately 2.16 acres. The project site is part of a 255 acre business center identified as Gateway Corporate Center which was =rove ove by Los Angeles County and completed by 1986. Gateway Corporate Center was proposed to service the eastern San Gabriel Valley's demand for professional office facilities in a location with regional access Development within the Center can generally be characterized as professional office, research and development and commercial. The Center was approved with extensive attention place on compatibility with the community and providing off-site improvements to respond to impacts created by the project. A Master Environmental Impact (MEIR� was prepared and approved by Los Angeles Regional Planning The document identified impacts principally related to geotechnical AADR98-16.ND 1/14/99 hazards, air quality, biota, archeological/paleontology, scenic quality and traffic /access. The mitigation measures developed and approved for Gateway Corporate Center Identified the Need for: Conditions Covenants and Restrictions (CC&Rs); detailed design guidelines that related to grading, pad develoment and Circulation within the Center: off --site traffic mitigation measures that included expansion of. Golden Springs Drive, and contribution to funds for improvements required for future development phases. The developer of the Center has met these mitigation measures, as prescribed in the MEIR. 9. � Surrounding Land Uses and Setting: Briefly describe the project's surroundings: The proposed project is locate on Lot 12 of Tract No. 39679 at 1550 S.

Mandatory Findings Resources _ of Significance _ A:\DR96-16.ND 1/14/99 4 PART 3 - DETERMINATION Project Number: DR 98-15 to be completed by Lead Agency On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. X I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the MITIGATION MEASURES described on an attached sheet have been added to the project. A NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a significant effect(s) on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets, if the effect is a "potentially significant impact" OR "potentially significant unless mitigated." An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project.

A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on.a project -specific screening analysis.) 2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4. "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an affect from "Potentially Significant Impact" to a "Less than Significant Impact. " The lead agency must described the mitigation measures and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063. (c)(3)(D). Earlier analyses are discussed in Section SVII at the end of the. checklist. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impact (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. A source list should be attached, and other sources used or individuals contacted should be cited in the discussion.

LAND USE AND PLANNING a. The project site is located within the General Plan land use designation of Professional Office (OP). This land use designation provides opportunity for the establishment of office -based working environments for general professional, and administrative offices, as well as support uses. The proposed project is for an office use with the tenant(s) not known at this time. Therefore, the proposed project is consistent with the General Plan land use designation for the project site. The project site is located within the Commercial -Manufacturing -Billboard Exclusion-Unilateral/Contract (C-M- BE-U/C) Zone. This zone allows for a variety of land uses by -right and with a Conditional Use Permit. The land uses contemplated within this classification includes but are not limited to the following: professional office, research and development, light manufacturing, medical offices and clinics, commercial retail, restaurants, hotels, physical fitness centers and government services. Other ancillary and support uses such as day care facilities, gymnasiums, dry cleaning services, and automobile rental and leasing agencies are permitted. This zoning classification encourages uses that can benefit the community in many ways including sales tax revenues and attracting an employee base with additional buying power. b. The proposed project does not conflict with applicable environmental plans or polices adopted by the City of Diamond Bar or other agencies with jurisdiction over this project. The proposed project is consistent with the General Plan's land use designation for the project site. The proposed project has been reviewed pursuant to CEQA requirements and found to have no significant effect on the environment. In .addition, the Gateway Corporate Center Design Guidelines provide development criteria applicable to all lots and addresses building envelope, lot coverage, parcel access, and design elements that restrict building height, exterior material and landscape pallet. Furthermore, the Gateway Corporate Center architectural committee conducts review of all such projects and approved this project. c. The proposed project is an office land use which is consistent with the General Plan, Zoning, the Gateway Corporate Center Design guidelines and the existing uses within the Center. Therefore, the proposed project is compatible with existing land uses in the vicinity. d. There are no agricultural resources or operations in the vicinity of the project area. e. Gateway Corporate Center is a professional/retail center that provides no existing residential development or opportunities for residential development. The proposed project is consistent with the character of the surrounding development and therefore AADR98-16.ND 1/14/99 25 will not disrupt or divide the physical arrangement of an established community including a low-income or minority community. 2. POPULATION AND HOUSING a. The nature of Gateway Corporate Center lends itself to attracting businesses in need of regionally accessible transportation opportunities, affordable lease rates and an educated employee base. The proposed tenants may possess employees who reside outside of the area. Existing employees will take one of the following actions: commute from outside the area; relocate to this area; or find different employment. It is assumed that some of the replacement personnel will be from this area. If not from this area, these employees will exercise on of the aforementioned actions. These factors were contemplated when the application to develop Gateway Corporate Center was approved by Los Angeles County and were found not to be in conflict with the regional housing projects for the area. The Center was found to provide consumers for the expanding housing opportunities present in the central San Gabriel Valley at the time of review. Presently, these conditions persist and the proposed project is, consistent with regional and local housing projections. Additionally, the Center does not provide existing residential development or opportunities for residential development. Therefore, the proposed project will not displace substantial numbers of people, thereby necessitating the construction of replacement housing elsewhere. b. The proposed project is located in an area with existing commercial development and existing infrastructure that can accommodate the proposed project and contemplated development as reviewed within Gateway Corporate Center's approved EIR. Therefore, it is not anticipated that this project will induce substantial growth either directly or indirectly. c. The proposed project ,site is a vacant, graded lot with a buildable pad, zoned for commercial -manufacturing development, consistent with the policies presented in the General Plan. Additionally, housing was not contemplated in Gateway Corporate Center's original approval. Therefore, the proposed project does not displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere. 3. GEOLOGICAL PROBLEMS a. No portion of the City has been identified as in an Alquist-Priolo Special Studies Zone. The closest fault is the Diamond Bar Fault, which is described as. a "small inactive local fault". Historically, there is no record of any earthquake with an epicenter in Diamond Bar of its Sphere of Influence, and no significant movement has ever been recorded for the Diamond Bar fault. The Whittier -Elsinore fault lies approximately four miles from the project site and has been active in historic times. Three faults with the greatest potential for activity are located in excess of 20 miles A:\DR9&16.ND 1/14/99 26 from the proposed project. Therefore, likelihood of fault rupture is limited. b. The proposed project lies within Zone 1, or Relative Ground Response Low (RGR1). Under current building, and engineering codes which consider ground shaking, any impacts from seismic ground shaking may be considered less than significant. c. The closest reservoir is the Ambushers Reservoir, approximately six miles form the project site, in a different drainage basin. If seiche occurs, it will not. affect the project site. Additionally, the project is not located near any volcanic mountain regions. There are no large bodies of water in close proximity to the project site. d. The proposed project site does not lie within a potential liquefaction zone. Additionally, the nature of the underlying material on the project site, the lack of ground water and the existing and proposed drainage conveyance devices within Gateway Corporate Center further diminish occurrences of liquefaction. e. Pursuant to the project's soils report, all slopes impacting the subject site are considered to be grossly and surficial stable. The slopes constructed during mass grading operations were built at a slope ration no greater than 2:1 (horizontal to vertical) and appear to be in accordance with previous project plans and specifications. These slopes appear to possess a safety factor of 1.50 or greater for gross stability. However, to minimize future erosion, the slope landscaping shall consist of a suitable proportion of deep rooted slope plantings classified as being drought resistant. Additionally, weather conditions may require additional erosion control measures such as matting, netting and plastic sheeting. f. The proposed project site is graded with a buildable pad created in conjunction with the development of Gateway Corporate Center. Pursuant to the project's soils report, Subsidence should be 0.1 feet due to earthwork operations. g. Pursuant to the project's soils report, the project site does contain expansive soil (sandy silt and shale). However, the proposed structures will be safe from excessive settlements by meeting the following requirements of: the City's Building Code; the City's Grading Ordinance; site inspections during grading and construction activities; "Specifications for Compaction Fill Operations" with in the project's soils report; deepened foundation into the underlying bedrock; and removing all disturbed soils prior to placement of any additional fill or pavement. h. Pursuant to the project's soils report, there are no significant or unique geologic of physical characteristics found on the project site. AADR98-16.ND 1!14/99 27 4. WATER a. Development of the project site will reduce pervious surfaces thereby increasing surface runoff. Runoff will be directed from on-site drainage devices into off-site drainage devices designed to accommodate runoff from the project site. The impacts associated from the increased runoff are expected to be insignificant. b. The project site is not located within a flood hazard area and adequate drainage devices have been incorporated into the drainage plan Gateway Corporate Center, as well as the proposed project. C., d., e. There is no body of surface water on the project site or the vicinity of the project. Therefore, no impacts related to surface water features, quality or flow will affect the project site. f. The proposed project will not impact the quantity of groundwater but will have an insignificant impact on the recharge of groundwater because of the reduction in pervious surfaces. g., h. The proposed project will not effect the direction or rate of flow of groundwater or groundwater quality due to conditions described above (a. through f.). i. The proposed project will not cause a significant reduction in groundwater supplies or the availability of groundwater for public water supplies. j. The proposed project is not a housing project. Nor is it within the 100 -year flood hazard area as mapped on the Federal flood Hazard Boundary or Flood Insurance Rate Map. As a result, structures will not impede or redirect flood flows. 5. AIR QUALITY a. Air quality will be affected during grading operation, however, it is not expected to be significant with procedures that will be implement to reduce air emissions. Additionally, such emissions are not expected to exceed those listed within the SCAQMD Air Quality Handbook. b. There are no known sensitive receptors within one-half mile of the project site. Therefore, any impacts to sensitive receptors will be insignificant. c. The proposed project's affect on air quality will be during grading operations only. Therefore, the affect will be temporary and will not resulting a considerable, cumulative net increase of any pollutant for which the project region is non -attainment under applicable federal or state ambient air quality standard. A:\DPA-16.ND 1/14/99 28 d. During the grading phase of the proposed project, diesel fuel odor may be emitted, however, based on the scope of the proposed grading operation. the impact is not expected to be significant. 6. TRANSPORTATION/CIRCULATION a. The applicant submitted a traffic impact analysis and site plan evaluation for the City's review and approval. The analysis, dated January 5, 1999 was performed by Linscott Law and Greenspan. The study indicates that the proposed project is expected to generate 640 daily two-way trips, with 89 trips (78 inbound, 11 outbound) anticipated during the AM peal commute hour. At the PM peak commute hour, it is anticipated that 123 trips (21 inbound, and 102 outbound) will be generated. The analysis indicated that this proposed project along with proposed office building projects for Lots 22 and 15 within Gateway Corporate Center will have a significant impact at the Copley Drive/Golden Springs Drive intersection. Additionally, the level of service of this key intersection degrades during the PM peak hour from acceptable LOS C to LOS F with traffic of the proposed project and the proposed project for Lots 22 and 15. However, implementation of recommended improvements will mitigate the impact of the proposed projects. For the intersection of Copley Drive/Golden Springs Drive, the analysis recommends changing the intersection's geometry to increase capacity. The recommended changes/improvements are as follows: re -stripe the northbound approach on Copley Drive to provide one left -turn and dual right -turn lanes. Modify the existing traffic signal accordingly. The identified improvements are expected to: mitigate the impact of future background and/or project traffic; improve Levels of Service to an acceptable range; and mitigate the significant impact of the development of all three lots (Lots 12, 15 and 22). As a condition of approval for the proposed project, the applicant shall be required to pay their fair share of the improvements. b. The proposed project is compatible with the established land uses within Gateway Corporate Center and land uses identified within the General Plan and Zoning Code. Hazards identified within the traffic report will be mitigated and instituted as conditions of approval. c. Site access will be located on Valley Vista Drive, just north of Bridge Gate Drive. The access will provide one ingress land and one egress lane. Based on the anticipated project traffic volumes, the driveway will be able to accommodate ingress and egress traffic without undue congestion. No modifications to.the existing striping on Valley Vista Drive are required to accommodate the project driveway. The traffic analysis evaluated the on-site circulation and deemed it adequate. Curb return radii 29 A:1DR98-16.ND 1/14/99 have been confirmed and are adequate for small service/delivery trucks as well as trash trucks. d. The proposed office building is approximately 39,000 square feet. Pursuant to the City's Development Code and Gateway Corporate Center's -development standards, one parking is required for each 250 square feet of gross floor area of general office use. Therefore, 156 parking spaces are required. However, the project site will provide 153 parking spaces. Therefore, the project is 3 parking spaces short of the required number. e. As referenced above in Item a., the level of service standard will be mitigate through the recommended improvement which will be a condition of approval for the proposed project. f. The�proposed project's design is consistent with the General Plan's goals, objectives and strategies supporting circulation and transportation. g. No rail, waterborne, or air traffic facilities or operations are in the vicinity of the proposed project. Therefore, the project will not impact these facilities or operations. 7. BIOLOGICAL RESOURCES a, -e. The project site is a vacant, graded site with a buildable pad area that does not contain locally designated natural communities or wetlands, In the absence of these conditions, a determination has been made that the site is incapable of supporting endangered, threatened or rare species. The site currently supports non-native grasses, various types of rodents and unlisted migrating animal species such as coyotes, deer and domestic species. 8. ENERGY a.,b. The proposed project will be required to comply with the UBC design and construction standards, thereby conforming to the City's energy conservation standards. c.
