Downtown Specific Plan Amendment

The City retained Ascent Environmental, Inc. in 2018 to help update the Downtown Specific Plan (DSP). The purpose of the update is to reflect changes in the retail market (with the rise of internet shopping) and consider allowing more jobs and housing near the Sunnyvale Caltrain Station.

The public hearing process for the Downtown Specific Plan (DSP) Amendment began in July 2020 and ended in August 2020. The City began amendments to the DSP in 2018 to address three potential developments and took the opportunity to revise the plan. The City Council approved the DSP amendments, Municipal Code changes, Environmental Review and two Development Agreements on Aug. 11, 2020. See Documents and Background tabs for additional information and reports.

Future Development Applications

Currently there are three developers with pending applications for five sites within the Downtown Specific Plan area. Their review is dependent on approval of the DSP amendment.

The largest proposal is from CityLine with three of the five sites. They are:

Block 18, Sub-block 1 located at 300 South Mathilda Ave. (at the corner of West McKinley Avenue). This project would construct a five-story office building with a combination of surface and underground parking on the existing vacant lot.

Block 18, Sub-block 2 located at 300 W. Washington Ave. This project would add an additional unit to an existing building.

Block 18, Sub-block 3, includes the site of the former Macy's building and the area around the historic redwood trees. The development of this site would include two seven-story office buildings and two ten-story residential buildings. The total project is 400 units with ground-floor retail and restaurants around a future plaza that retains the existing redwood trees, and includes underground parking.

Block 18, Sub-block 6 consists of the existing surface parking lot south of West Washington Avenue between Sunnyvale and Murphy Avenues. The development of this site would involve the construction of 392 residential units with ground floor retail or restaurant uses and would include underground parking.

The other two development applications are:

Located at 100 Altair Way, this project would replace the existing three-story mixed use residential building and downtown post office with a seven-story office building with underground parking.

Located at 111 W. Evelyn, this project would replace the existing parking lot at the corner of Sunnyvale Avenue and W. Evelyn Avenue with a four-story office building with underground parking.

The City first adopted the Downtown Specific Plan (DSP) in 2003 to guide future development in the heart of Sunnyvale. The goal of the DSP is to create an enhanced downtown that continues to be the heart of the community, providing a variety of destinations in a pedestrian-friendly environment. Since the DSP's adoption in 2003, the area changed from a downtown shopping mall to a vibrant mixed-use environment with places for people to live, work, and visit.

In 2015 and 2017, three property owners approached the City with requests to allow for more development on several sites near the Sunnyvale Caltrain Station. The City Council allowed the property owners to submit applications. At the same time, the City Council recognized that these projects would require amendments to the DSP and authorized hiring an outside firm to help evaluate and update the DSP. The City hired Ascent Environmental, Inc., the selected firm, in 2018.

Summary of Proposed DSP Update

The proposed updated plan keeps the Vision for Downtown (adopted in 2003) as "An enhanced traditional downtown serving the community with a variety of destinations in a pedestrian-friendly environment." The update:

  • Acknowledges the changing retail environment
  • Includes flexibility for increased density through incentive programs or Community Benefits 
  • Strengthens the design guidelines
  • Provides guidance to enhance the pedestrian experience and include more wayfinding such as signs, gateways and other icons

To create consistency with the DSP amendments, the City Council also approved Municipal Code text changes and a Zoning Map change. In addition, the City Council approved two Development Agreements (for two of the three developments). An Environmental Impact Report (EIR) was prepared for the proposed DSP amendments and all three development proposals and the City Council approved the Final EIR.

Downtown Parking District Study

The City Council also considered study findings and recommendations on the Downtown Parking District (2016 Council Study Issue - CDD 11-02 [PDF download] - Downtown Development Policies for Parking). The Study found that there is currently an overall surplus of parking that will continue in the foreseeable future. The Study recommended a series of near-term, mid-term and long-term actions to improve management of the parking district and support a successful and vibrant Downtown. Staff will return to the City Council with short-term recommendations.

Development Agreements

The City Council approved two separate Development Agreements for two sites within the DSP - STC Venture and Kasik. A Development Agreement is a tool used by cities to guarantee development approvals to the landowner and to provide additional benefits to both the City and a developer that are otherwise not available. The approved DSP amendments enable additional housing units, additional square footage of offices uses, and greater building height based on development incentive programs or a Development Agreement.

  • A 30-month freeze on impact fee amounts
