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:

Consider Changing Zoning in Area bounded by Route 237, US-101 and Lawrence Expressway

PROJECT DESCRIPTION AND LOCATION (APN):

Reconsider industrial zoning in the area generally bounded by (Route 237, US-101, and Lawrence) Expressway.

FINDINGS:

The Director of Community Development of the City of Sunnyvale, California, hereby determines that an environmental impact report is not required. The above determination is based on the fact that the use is not in conflict with the adopted General Plan and the Zoning Ordinance. There are sufficient environmental controls incorporated into the Zoning regulations as to ensure no significant detrimental effect by any proposed use allowed as a matter of right and, in the case of a PD overlay or any application for a use permit, site and architectural control will be exercised by the City. No endangered species are known to depend on this site for habitat.

DISCUSSION OF IMPACTS:

Noise: The Noise Sub-element for the City of Sunnyvale states that acceptable noise exposure for residential uses is 60 LDN (the average sound level in decibels during a 24-hour period) and 45 dB for interior noise. Interior noise levels are also required by Title 24 of the California Code of regulations.

Exterior Noise: The study area is within Touch and Go pattern for Moffett Air Field. Contours relating to the airport noise level indicate that the study area is outside the noise contours for the field and is within acceptable exterior noise levels (60 LdN) for residential uses. This area is located in proximity to Highway 237 and Fair Oaks Avenue, a Class I arterial. According to projected noise levels for 2010, a portion of the study area would be subjected to LDNs of 60 or higher. In order to mitigate those noise effects, each residential project will need to conduct a noise study to determine appropriate individual construction mitigation to ensure acceptable noise levels for exterior areas.

Interior Noise: All residential projects will need to comply with Title 24 of the California Code, stating that each project must provide adequate sound insulation to ensure interior noise levels not to exceed 45 dB. As this is a code requirement, no additional mitigation measures are necessary.

Construction Noise: The construction activity associated with development of new residential units has noise impacts on surrounding properties. Title 16 of the Sunnyvale Municipals Code limits hours of construction for all projects to between the hours of 7 a.m. and 6 p.m. daily Monday through Friday. Saturday hours of construction shall be between 8 a.m. and 5 p.m., and construction is prohibited on Sundays and holidays. These limitations will ensure there are no significant noise impacts for surrounding residential properties.

Traffic and Transportation: The increase in residential units will increase peak hour trips on adjoining roads. A traffic impact analysis has been conducted to identify the specific impacts and mitigation needed in order to maintain appropriate levels of service for nearby roads and intersections. This mitigation includes adding an eastbound and westbound right turn lanes at the intersection of Lawrence and Tasman. The improvements associated with the Lawrence/Tasman intersection are already included as part of the long-term traffic improvement plan for General Plan buildout.

Population and Housing: The proposed project could increase the number of allowed housing units by 588. This would increase population in the area, and subsequently demand for City services, parks, and traffic. A separate analysis of each possible impact is included in this environmental document and appropriate measures are being taken in order to mitigate any potentially significant impact associated with this increase in housing units.

Hazardous Materials: One semiconductor tool manufacturer utilizing toxic compressed gases is located in the study area. A large semiconductor manufacturer, also using toxic gases, is situated within 1000 ft. of the study area. Both facilities have the potential of releasing hazardous gases to the environment. However, through integration of specific engineering and administrative controls into the industrial process, as mandated by the California Fire Code and Sunnyvale Toxic Gas Ordinance, these facilities have significantly reduced the potential impacts to the surrounding community.

Public Services: The increase in population will incrementally increase the need for public services. As this increase is a small percentage of the existing area served, evaluation of the impacts can be conducted on a case by case basis and incorporated into service budgets without specific mitigation from individual projects.

Geology and Soils: The study area is located in a liquefaction zone. The City of Sunnyvale requires submittal of soils analysis prior to issuance of a building permit. As part of the building permit review, the City ensures that appropriate construction techniques are used in order to mitigate any potential effects of the liquefaction zone.

Recreation: The proposed increase in units will not adversely affect or cause significant environmental impacts on City parks. It will increase demand for parks and open space and associated recreational services. The City’s existing level of service is 6.3 acres/1000 population. In order to maintain that standard, the Sunnyvale Municipal Code requires dedication of park land or payment of a park in-lieu fee for construction of every new residential unit. This fee is approximately $4,300/medium or high-density unit. The fees collected from this construction can be used to acquire additional park land so that the City may maintain existing levels of service. The City currently owns a 5.3 acre parcel within the study area that is designated for future conversion to a neighborhood park. The City will pursue acquisition of additional park land as funds become available and as projects develop.

Any person prior to 5:00 p.m. on Tuesday, June 4, 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 Mitigated Negative Declaration will be considered by the adopting authority, whose action on the protest may be appealed.

Description of the 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.

This project consists of consideration of a General Plan Amendment and associated Rezone to allow an increase in residential density in Site 7 of the Futures Sites as well as allowing up to 140,000 sq. ft. of neighborhood-serving retail. The study area consists of approximately 81 acres south of Highway 237, North of 101 and west of Fair Oaks Avenue. These parcels are currently planned for conversion from existing industrial uses to medium-density residential development.

Two scenarios were considered as part of this project:

  • Scenario A: to rezone the area north of Tasman Drive to an exclusively residential zoning district allowing up to 36 du/acre. Also, zone the southwest corner of Tasman Drive and Fair Oaks Avenue to a mixed-use designation allowing 140,000 sq. ft. of commercial development and up to 66 housing units. This plan would result in a net new increase of zero for housing units and 140,000 sq. ft. for retail.
  • Scenario B: would include Scenario A and rezone the portion south of Tasman Drive to a 36 du/acre ITR designation. This zoning district (MS/R4/ITR/PD) would allow for the continued enhancement and expansion of existing industrial uses, while promoting conversion to high-density residential use. This scenario would result in a net new increase of 588 housing units and 140,000 sq. ft. of retail.

This environmental review is based on Scenario B as the highest possible environmental impact. All of the information contained in this document is based on the 588-unit increase as well as additional 140,000 sq. ft. of retail.

DETERMINATION: (To be completed by the 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.

q

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 revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.

T

I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.

q

I find that the proposed project MAY have a "potential significant impact" or "potentially significant unless mitigated" impact 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. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed.

q

I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

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:

  1. Earlier Analysis Used. Identify and state where they are available for review.
  2. 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.
  3. 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.

    DISCUSSION OF IMPACTS:

    Noise: The Noise Sub-element for the City of Sunnyvale states that acceptable noise exposure for residential uses is 60 LDN (the average sound level in decibels during a 24-hour period) and 45 dB for interior noise. Interior noise levels are also required by Title 24 of the California Code of regulations.

    Exterior Noise: The study area is within Touch and Go pattern for Moffett Air Field. Contours relating to the airport noise level indicate that the study area is outside the noise contours for the field and is within acceptable exterior noise levels (60 LdN) for residential uses. This area is located in proximity to Highway 237 and Fair Oaks Avenue, a Class I arterial. According to projected noise levels for 2010, a portion of the study area would be subjected to LDNs of 60 or higher. In order to mitigate those noise effects, each residential project will need to conduct a noise study to determine appropriate individual construction mitigation to ensure acceptable noise levels for exterior areas.

    Interior Noise: All residential projects will need to comply with Title 24 of the California Code, stating that each project must provide adequate sound insulation to ensure interior noise levels not to exceed 45 dB. As this is a code requirement, no additional mitigation measures are necessary.

    Construction Noise: The construction activity associated with development of new residential units has noise impacts on surrounding properties. Title 16 of the Sunnyvale Municipals Code limits hours of construction for all projects to between the hours of 7 a.m. and 6 p.m. daily Monday through Friday. Saturday hours of construction shall be between 8 a.m. and 5 p.m., and construction is prohibited on Sundays and holidays. These limitations will ensure there are no significant noise impacts for surrounding residential properties.

    Traffic and Transportation: The increase in residential units will increase peak hour trips on adjoining roads. A traffic impact analysis has been conducted to identify the specific impacts and mitigation needed in order to maintain appropriate levels of service for nearby roads and intersections. This mitigation includes adding an eastbound and westbound right turn lanes at the intersection of Lawrence and Tasman. The improvements associated with the Lawrence/Tasman intersection are already included as part of the long-term traffic improvement plan for General Plan buildout.

    Population and Housing: The proposed project could increase the number of allowed housing units by 588. This would increase population in the area, and subsequently demand for City services, parks, and traffic. A separate analysis of each possible impact is included in this environmental document and appropriate measures are being taken in order to mitigate any potentially significant impact associated with this increase in housing units.

    Hazardous Materials: One semiconductor tool manufacturer utilizing toxic compressed gases is located in the study area. A large semiconductor manufacturer, also using toxic gases, is situated within 1000 ft. of the study area. Both facilities have the potential of releasing hazardous gases to the environment. However, through integration of specific engineering and administrative controls into the industrial process, as mandated by the California Fire Code and Sunnyvale Toxic Gas Ordinance, these facilities have significantly reduced the potential impacts to the surrounding community.

    Public Services: The increase in population will incrementally increase the need for public services. As this increase is a small percentage of the existing area served, evaluation of the impacts can be conducted on a case by case basis and incorporated into service budgets without specific mitigation from individual projects.

    Geology and Soils: The study area is located in a liquefaction zone. The City of Sunnyvale requires submittal of soils analysis prior to issuance of a building permit. As part of the building permit review, the City ensures that appropriate construction techniques are used in order to mitigate any potential effects of the liquefaction zone.

    Recreation: The proposed increase in units will not adversely affect or cause significant environmental impacts on City parks. It will increase demand for parks and open space and associated recreational services. The City’s existing level of service is 6.3 acres/1000 population. In order to maintain that standard, the Sunnyvale Municipal Code requires dedication of park land or payment of a park in-lieu fee for construction of every new residential unit. This fee is approximately $4,300/medium or high-density unit. The fees collected from this construction can be used to acquire additional park land so that the City may maintain existing levels of service. The City currently owns a 5.3 acre parcel within the study area that is designated for future conversion to a neighborhood park. The City will pursue acquisition of additional park land as funds become available and as projects develop.
