Realizing the Water Supply Benefits of Daylighting a Historic Creek
Yosemite Creek Daylighting Project
The Upper Yosemite Creek Daylighting Project restores the natural flow of the ephemeral historic Yosemite Creek in order to better manage flows from 110 acres of McLaren Park . The creek will flow along the northern edge of the park from Yosemite marsh and around the Louis Sutter Playground soccer and softball fields ; the creek channel will convey stormwater and alleviate localized flooding issues as well as provide storage and infiltration facilities . This is the first creek daylighting project initiated by the City and will reintroduce habitat and provide opportunities for community learning and beautification . In early 2018 , the project team began transitioning from the planning to the design phase , which will include identifying design elements such as material color , construction methods , and construction coordination .
Integrating Green Infrastructure into Design
Stormwater Management Requirements and Design Guidelines
Managing stormwater , which can overwhelm our combined sewer system during large storm events , is critical to protecting the quality of San Francisco Bay . The San Francisco Stormwater Management Requirements and Design Guidelines describe the requirements for stormwater management for development and redevelopment projects subject to the San Francisco Stormwater Management Ordinance and give project proponents the tools to achieve compliance . By encouraging residents to incorporate green infrastructure and design into projects , the SFPUC is not only conserving potable supplies , but protecting the health of San Francisco Bay and the Pacific Ocean by redirecting water from treatment plants and reducing ocean discharge . One example of this is the Lake Merced Well Green Roof , where compliance with the Stormwater Management Ordinance has integrated innovation into the SFPUC ’ s own assets .
Greening Our Roofs
Lake Merced Well Green Roof
The Lake Merced Well Station incorporates a green roof that visually blends the well facility with the landscape to the west and south of the facility . A viewing platform was created on the sidewalk above the well station to increase visual exposure to the site from the public area . The green roof utilizes native plants and provides visual continuity as well as sustainable benefits including reduction of stormwater runoff , increased energy efficiency , reduction in life cycle costs , and potential habitat for birds . By providing these benefits , this project is an ideal example of how we can look holistically at our resources to develop projects that provide multiple benefits .
