Figure 9. High-density ResidentialIn San Francisco, high-density residential development is classified as 40 or more living units per acre. Some defining characteristics of high-density residential are zero-lot line development, reduced, public open space, and high levels of imperviousness. In this context, the greatest opportunities for stormwater management reside in replacing impervious surfaces with pervious surfaces and adding green space to roofs and interior courtyards. Ample roof space with relatively low pollutant loads provides opportunities for eco-roofs and rainwater harvesting. Interior courtyards can accommodate landscape-based BMPs, permeable paving, and subsurface treatment or capture systems. Sidewalks and streets adjacent to high-density residential development are often the nearest public open spaces available to residents. As such, they are ideal places to site stormwater management BMPs that also improve streetscape aesthetics and provide wildlife habitat, such as biofiltration areas, street trees, green walls, and bioretention bulbouts. All of these measures help to manage stormwater runoff; they also reduce the volumes of stormwater generated by the site in the first place.

seFigure 11. Mixed UseMany new, redevelopment, and infill projects in San Francisco include mixed-use areas. Mixed use development fosters a high level of activity throughout the day, resulting in an active public realm. Roofs, public plazas, setbacks, parking lots, and the public right-of-way are all spaces that can double as LID measures that improve the quality of the public realm and achieve stormwater management goals. Of these spaces, roofs generally have the lowest pollutant loads while streets have the highest. The commercial elements of mixed use development sometimes require special attention. For example, restaurants and light industrial activities will need to implement source controls targeting grease, litter, and other food wastes.

GUIDANCE FROM OTHER CITIES
NEXT STEPS/ACTION PLAN
• Best practice policy and implementation research
• Biodiversity Stormwater and energy studies
• Follow up targeted conversations with key stakeholders and practitioners
• Policy recommendations
• Green Roof for healthy cities conference
• Education/Outreach by Green Roof Alliance
• Greenroof Tours
• Pilot projects
• Investigate city initiated green roofs, review City Capital plan to see what major buildings the city is planning to fund for new construction or renovation (ie 1SVN)
• Determine when a dedicated codified policy is needed vs. Removal of barriers (ie SFPUC clarity on planning height and neighborhood notification requirements)
Potential incentives:
Faster approval/construction permitting process
Loans or grants for capital costs
Reduced storm water/wastewater system development charges
Reduce stormwater/wastewater usage fees
Reduced size of stormwater management ponds or cisterns
Grants rewarding energy efficiency or economic and environmental objectives
Density bonus/ larger floor area ratio
Satisfy minimum parkland / green space requirements
Greenhouse gas emissions trading credits
