MITIGATED NEGATIVE DECLARATION

This Mitigated Negative Declaration has been prepared in compliance with the provisions of the California Environmental Quality Act of 1970, as amended, and Resolution #193-86.

PROJECT TITLE:

Application for a General Plan Amendment, Rezone, Special Development Permit and Tentative Map by Classic Communities.

PROJECT DESCRIPTION AND LOCATION (APN):
Application for related proposals on a 4 acre site located at 1002 Washington Avenue (Mary Manor Shopping Center) in a C-1/PD (Neighborhood Business/Planned Development) Zoning District. (APN: 161-37-035)

2001-0354 - General Plan Amendment to change a 2.87 acre portion of the 4 acre site from Neighborhood Shopping to Low-Medium Density Residential and;

2001-0355 - Rezone a 2.87 acre portion of the site from C-1 (Neighborhood Business) to R-1.7/PD (Low Medium Density Residential/Planned Development) Zoning District; and the remainder of the site to C-1/PD (Neighborhood Business/Planned Development);

2001-0356 - Special Development Permit to allow 31 single family detached homes and a commercial building.

2002-0390 - Tentative Map to subdivide one parcel into 31 residential lots, one common lot, and one commercial lot.

FINDINGS:

The Director of Community Development of the City of Sunnyvale, California, hereby determines that an environmental impact report is not required. There are sufficient environmental controls incorporated into the zoning regulations to ensure no significant detrimental effect.

The above determination is based on information provided by the applicant in an "Application for Environmental Clearance" and is based on the fact that sufficient environmental controls are incorporated in the Zoning and Subdivision regulations as to ensure no significant detrimental effect; and that site and architectural control will be exercised over the proposed development by the Planning Commission and City Council. No endangered species are known to depend on this site for habitat.

Any person prior to 5:00 p.m. on Tuesday, August 22, 2002 may protest this Mitigated Negative Declaration in writing. Such protest shall be filed in the Department of Community Development, 456 W. Olive Avenue, Sunnyvale and shall include a written statement specifying anticipated environmental effects which may be significant. A protest of a Negative Declaration will be considered by the adopting authority, whose action on the protest may be appealed.

MITIGATION MEASURES:

NOISE (a) Due to the proximity of certain residential units to Mary and Washington Avenues, certain mitigation measures are required to ensure adequate decibel levels inside the house and in the exterior yard area. A noise consultant, Charles M Salter Associates, Inc., conducted a professional evaluation of the area and determined that the following measures are necessary to ensure no more than an Ldn of 45dB with doors and windows closed and an exterior noise exposure Ldn of no more than 60dB.

What and Where: Install sound-rated windows for homes along Mary Avenue to achieve 45dB or less. Include mechanical ventilation systems at the first row of dwelling units along both Washington and Mary Avenue.

How: Indicate each home and show details of both window and mechanical ventilation systems on the building permit plans.

When: Prior to building permit final.

Who: The City will require this to be indicated on the building permit plans prior to issuance.

What and Where: Separate the backyard of Lot 27 from Washington Avenue with a 6 ft. high solid fence. If the fence is wood it should have no cracks or gaps and must have a minimum surface density of two pounds per sq. ft.

How: Indicate the location and type of fencing for Lot 27 on the building permit plans. Include details that show material complies with these requirements.

When: Prior to building permit final.

Who: The City will require this to be indicated on the building permit plans prior to issuance.

What and Where: Require an analysis of rooftop mechanical equipment at the commercial development to demonstrate the equipment will not exceed either an interior or exterior noise level standard for the surrounding residential units.

How: Submit a roof plan showing the type of equipment proposed and an associated noise study analyzing the extent of the noise and it’s effect on surrounding properties. This study should suggest any requirements needed to mitigate noise to acceptable levels as indicated in the Noise Sub-element.

When: Prior to building permit issuance.

Who: The City will require this to be analyzed and all applicable measures to be indicated on the building permit plans prior to issuance.

EVALUATION OF ENVIRONMENTAL IMPACTS
1)	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)	Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required.
4)	"Negative Declaration: Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 17, "Earlier Analysis," may be cross-referenced).
5)	Earlier analysis 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). In this case, a brief discussion should identify the following: Earlier Analysis Used. Identify and state where they are available for review. Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project
6)	Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (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.
7)	Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion.
8)	This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project’s environmental effects in whatever format is selected.
9)	The analysis of each issue should identify: (a) the significance criteria or threshold used to evaluate each question; and (b) the mitigation measure identified, if any, to reduce the impact to less than significance.

PROJECT DESCRIPTION

The 4-acre project site is located along Mary Avenue, a Class 2 Arterial Road. The site is bordered on three sides by roads: Mary Avenue, West Washington Avenue and Leota Avenue. The site is currently developed with a one-story 36,000 sq. ft. shopping center. Most of the site is used as the parking lot, and almost all significant landscaping is located at the perimeter of the site in the public right of way.

The immediately adjacent uses consist of medium density residential uses such as apartments and townhomes. There is a vacant parcel directly to the north of the site. A detached single family neighborhood lies beyond these apartments and townhomes. Both Vargas Elementary School and St. Cyprian School are located within 1,000 ft. of the project site.

The proposed project uses 2.87 acres of the parcel for 31 detached single-family homes. Private roadways provide access to these homes. The remaining 1.13 acres along Mary Avenue will be used for an approximately 12,276 sq. ft. commercial building. A pedestrian walkway links the residential portion to a new commercial site.

To achieve this, a General Plan Amendment, Rezone, Special Development Permit and Tentative Map must be approved.

DISCUSSION OF IMPACTS THAT ARE LESS THAN SIGNIFICANT

NOISE (d) Although the site is already developed, the project will introduce short-term and temporary additional sources of noise to the project area during construction. Through the City’s implementation of the Municipal Code noise regulations, this impact will be lessened to a less than significant level during construction.

POPULATION AND HOUSING (a) The project will be adding 31 residential units to the City’s Housing stock, which will increase the population in that section of the City. However, The City contains approximately 50,000 housing units, and this proposed increase is not substantial in relation to the existing population or adequacy of infrastructure to support it.

PUBLIC SERVICES – PARKS (a) The development of detached single family homes increases the demand on park services in the area. The City’s standard is 6.3 acres of parkland per 1000 population. In order to address this additional demand, Sunnyvale Municipal Code Chapter 18.10 requires the developer of any new residential development to pay park fees prior to approval of the Final Map. These monies are intended to allow the City to buy additional land for park areas within the City.

GEOLOGY AND SOILS (ii) and (iii) The project site is not located in an area with any active faults, but may experience strong seismic ground shaking in the event of an earthquake. Through the City’s implementation of the Uniform Building Code requirements for area’s with potential for seismic activity this aspect of the project will be reduced to a less than significant level.

TRANSPORTATION AND TRAFFIC (f) The project may propose some deviations from the parking standard. As part of their review, the Planning Commission and City Council will review the analysis provided by staff and make their decision based on adequacy of parking provided, among other factors.
