Downtown Specific Plan


Project Overview

The City of San Dimas is embarking on the creation of its first Downtown Specific Plan. The new Specific Plan will help establish a planning and zoning framework for encouraging innovative, transit-oriented development in the greater downtown area while preserving the character of the historic commercial district. During the planning process, new housing, retail, employment, and hospitality uses in the downtown area will be proposed to complement a new Metro Gold Line passenger light rail and transit station opening in 2025. Several opportunity sites within walking distance of the transit station will allow significant potential for infill development and adaptive reuse of existing underutilized properties in the downtown.   


One of the key outcomes of the process will be the creation of design guidelines for both private development and the public realm. These guidelines will encourage future development to meet the community’s standards and expectations and to create a strong sense of community identity and place.

Purpose of the Downtown Specific Plan:

The Downtown Specific Plan offers:

  1. A community-supported vision and guiding principles that encourages a vibrant and pedestrian-friendly downtown.
  2. Goals and policies to guide decision-makers in achieving the community’s vision for the downtown area.
  3. Actions to be taken by the City to develop projects and partnerships that implement the goals and policies.
  4. Phased catalytic projects to spur new economic investment and residential and commercial development in downtown.
  5. New objective design and development standards to provide clear guidance for property owners, developers, and City staff.
  6. Streetscape improvements to activate the public realm, providing an inviting and engaging pedestrian-friendly environment.
  7. Fulfillment of the goals, policies, and actions of San Dimas’ General Plan by promoting orderly growth, and efficiently utilizing existing infrastructure and services.

Components of the Specific Plan:

Land Use & Housing:
The Specific Plan will address development projections for residential and non-residential land use that reflect the market analysis; land use designation, distribution, and intensity of development.

Mobility & Parking
The Specific Plan will address roadway hierarchy and cross sections, potential improvements to transit routes, facilities, and accessibility; and alternative and active transportation networks, linkages, and accessibility. The Specific Plan will also cover parking and related issues as appropriate.

Infrastructure & Public Services
The Specific Plan will identify necessary infrastructure and utilities, improvements and relocations, as needed to support the City, including storm drain, wastewater, water, energy, and telecommunications systems.

Open Space & Environment Framework
The Specific Plan will describe and illustrate conceptual plans, policies, and proposals for open space and the environment with an emphasis on enhancing the design and use of outdoor amenities.

Urban Design & Placemaking Framework
The Specific Plan will promote local identity and placemaking through architectural form and character, historic and cultural resource preservation and enhancement, public art programming, and signage.

 Community Involvement

A key component of the process is public participation. As part of the outreach efforts, Staff will seek public input from residents, business and property owners, and stakeholders. Community workshops will be held throughout the process to allow, an interactive website to  collect comments and input has been created, and a Community Advisory Committee (CAC) and a Technical Advisory Committee (TAC) will be formed.

Community Workshops
A total of five public community workshop meetings will be held at various stages of the planning process. The main goal of these workshops will be to solicit valuable community input on the process, with the overall intent of informing the public about the project, achieve a general consensus and vision for the study area, and allow for valuable feedback and evaluation of concepts and recommendations. Community members can get involved in the creation of the Specific Plan by providing local insights, feedback, and comments during the following Community Workshops:

MindMixer Website

In an effort to provide different avenues of public participation, the City created an  interactive website. The MindMixer website allows community members to comment and provide input through interactive means. The website serves as a unique online forum to stimulate discussion and elicit feedback through interactive polls and map, and surveys. The community is strongly encouraged to get involved by visiting the website at and take the survey, share ideas and provide comments. 


Community Advisory Committee (CAC)
The CAC is comprised of residents, local business owners, an architect/resident, and representatives from the Chamber of Commerce, Downtown San Dimas/Bonita Corridor, San Dimas Senior Citizens Club and the Sheriff’s Department. The goal of the CAC will be to provide a diversity of viewpoints, valuable input, and create dialogue to question the plan’s purpose, process, and potential effects, when necessary.

Technical Advisory Committee (TAC)
The TAC is comprised of City Staff from various departments/divisions, project team consultants, and a representative each from the Bonita Unified School District, Metro, Golden State Water Company, Active San Gabriel Valley (SGV), and Foothill Transit. Information gathered from TAC meetings, may include ideas and efforts by their respective organizations, and various studies and reports will help the City in determining where improvements can be made to create a more effective, equitable, and sustainable DTSP.
