About the Database

TransForm’s GreenTRIP Parking Database includes data gathered at multi-family residential sites around the San Francisco Bay Area. The data shows parking supply and utilization at each site and information about the residential units in the building. You can browse the parking database, or apply selection criteria to search for sites.

Using the Map

Searching the Map

Begin by entering a location in the address above the map on the right side. Click the “Search” button and the map will zoom to that location. You may enter an address, zip code, neighborhood, city or county name. For this example we have typed in San Jose.

You can use the Google controls on the left side of the map to zoom in and out, and go to google streetview. As you zoom in on the map, the map will become more detailed, and you will see, transit lines, transit stations, bus stops, and car sharing sites.

Display Boundaries

Clicking on the “Boundaries” drop down menu gives you the option of displaying no boundaries, or outlines of priority development areas, county or city boundaries on the map.

In the example below, "Cities" has been selected.

Building Labels

Clicking “Building Labels” gives you a drop down menu of map themes to display. Options include building icons; Housing Affordability, which indicates whether a building’s rents are market rate or affordable; % of Parking Unused, which indicates high, medium or low levels of excess parking provided at a building.

In the example below, the "Housing Affordability" label has been selected.

Building Selection

Next to "Buildings" are buttons that allow you to Select or Clear All buildings, and Hide or Show unselected buildings. For all building label types, the marker background will be white if the building is not selected.

Clicking on a building label on the map pops up an information box where building and parking information is displayed.

The Building tab includes property information such as location, number of units and unit type. Clicking on the “Building Report” button provides a print-ready 2 page Building Report. You may click on the “zoom to building” button to zoom to the building’s location. Clicking on “Deselect Building” button unselects the building, while “Add to Selection” selects a building.

The Parking tab includes number of parking spaces, parking space usage, and traffic reduction strategies available to residents. The “Building Report”, “zoom to building” and “select / deselect” buttons are also available.

Viewing the Comparison Report

The Comparison Report provides information on all selected buildings. Aggregated summary statistics for all selected buildings, including aggregated total parking spaces, number of unused parking spaces and cost of unused parking spaces are given.

The number of buildings in the Comparison Report and any filters applied are reported. You may clear all filters by using the “Clear All Criteria“ button. Clearing all filters shows all buildings. You may individually clear filters by clicking on the “x” next to the filter.

Below the summary statistics, each building is listed individually, and includes information on building parking, residential units and transportation information. You can sort the buildings by clicking on the column headings. Clicking on the building name generates a detailed print-ready Building Report.

Searching the database

When you first arrive at the website, the default view is to show all buildings on the map and in the Comparison Report.

You can choose to narrow the selected buildings on the map and in the report by applying search criteria based on building, parking, location and transportation characteristics. Each time you apply a criteria, the number of buildings selected will update, the map will update and your filter criteria will be displayed, and the comparison report will update. You may select as many criteria as you like.

Building Tab

Using the checkboxes you can specify buildings by the number of units, unit type, unit size, % of units below market rate. A drop down menu of developer and project names can be used to select buildings. In this example we have chosen Development Type: Mixed Use. The number of buildings selecting meeting these criteria is 25.

Parking Tab

Clicking on the Parking tab gives options to specify buildings by Average Parking Spaces/Unit Provided, % of Used Spaces, Parking Type, Surrounding Street Parking, Assigned Parking and Parking Permits. In this example we have chosen Parking Type: Structure. The number of buildings selected is now 14.

Viewing the Building Report

You can create a Building Report for the buildings in your Comparison Report. Click on the name of the building to create the Building Report. In this example we have chosen Gish Apartments.

The Building Report is a two page printer friendly report with building details.

A resident and residential parking profile, including parking availability and usage, are detailed.

On the second page, included are a map, parking information, and traffic reduction strategies available to resident on site and in the surrounding neighborhood.
