Big changes are coming to Treasure Island in San Francisco. HCD recently joined the San Francisco Transportation Authority and other honored guests to celebrate the groundbreaking of the Hillcrest Road Improvement project. This project, which received $30 million from HCD’s Infill Infrastructure Grant program, will change Hillcrest Road into a one-way, two-lane road with a designated on-road bike lane—leaving space to convert the bike lane to a multi-modal pathway for pedestrians and cyclists in the near future.
The conceptual design includes the construction of new retaining walls further set into the hillside, guardrails, street and pedestrian level lighting, and concrete barriers for safety. This Capital Improvement Project will support the development of over 800 new homes destined for construction on the island as a part of the Treasure Island Master Plan project.
The Treasure Island Master Plan project will use over 400 acres on the island to create a new San Francisco neighborhood. This neighborhood will focus first on affordable housing for homeless island residents and will create the sustainable infrastructure necessary to support the new community, including transportation connections, access to parks, restaurants, stores, and more.
