• Planning & Design
• Storm Water Pollution < One Acre

For projects of less than one acre, develop a Storm Water Pollution Prevention Plan (SWPPP) that has been designed, specific to its site, conforming to the State Storm water NPDES Construction Permit or local ordinance, whichever is stricter, as is required for projects one acre or more. The plan should cover prevention of soil loss by storm water run-off and/or wind erosion, of sedimentation, and/or of dust/particulate matter air pollution.

• Bicycle Parking and Changing Rooms

A) Short-term bicycle parking

B) Long-term bicycle parking

C) Changing Rooms-for buildings with occupants over 10 tenant-occupants

• Designated Parking

Provide designated parking for any combination of low-emitting, fuel-efficient, and carpool/van pool vehicles.

• Light Pollution Reduction

Comply with lighting power requirements in the California Energy Code, CCR, Part 6, and design interior and exterior lighting such that zero direct-beam illumination leaves the building site

• Grading and Paving

The site shall be planned and developed to keep surface water from entering buildings. Construction plans shall indicate how site grading or a drainage system will manage all surface water.

• Energy Efficiency
• California Energy Commission

The California Energy Commission will continue to adopt mandatory building standards.

However, it is the intent of this code to encourage buildings to achieve exemplary performance in the area of energy efficiency.

• Water Efficiency and Conservation
