RMCC Products That Can Help

SS

Credit 5.1 - Site Development: Protect or Restore Habitat

Implementing concrete parking garages within buildings can limit site disturbance. Parking garages within structures help maintain existing natural areas that would be taken out by paved parking.

Concrete for parking garages

SS

Credit 5.2 – Site Development: Maximize Open Space

Concrete parking garages on lower floors can be used to help reduce the footprint of the development.  Need to exceed the local zoning’s open space requirement by 25%.

Credit 6.1 – Stormwater Design: Quantity Control

Use of pervious concrete can reduce rate and quantity of stormwater runoff. If building site has an existing imperviousness of greater than 50 % the rate and quantity of stormwater runoff must be reduced by 25%. If existing imperviousness is less than 50% the postdevelopment discharge rate and quantity from site can not exceed the pre-development rate and quantity

Credit 7.1 – Heat Island Effect: Non-Roof

Provide any combination of the following strategies for 50% of the site hardscape (including roads, sidewalks, courtyards and parking lots):
   - Shade (within 5 years of occupancy
   - Paving materials with a Solar Reflectance Index of at least 29
   - Open grid pavement system
OR
Place a minimum of 50% of parking spaces under cover (defined as under ground, under deck, under roof or under a building).
