SS 5-8 Flashcards
What is SS Credit 5 called?
Reduced Site Disturbance
What is the intent of the Reduced Site Disturbance Credit?
Conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity.
How many points are available for Reduced Site Disturbance?
Two
What is required on Greenfield sites for Reduced Site Disturbance Credit 5.1?
Limit site disturbance to 40 feet beyond the building perimeter; 5 feet beyond primary roadway curbs; 25 feet beyond constructed areas with permeable surfaces.
What is required on previously developed sites for Reduced Site Disturbance Credit 5.1?
Restore a minimum of 50% of the site area by replacing impervious surfaces with native or adapted vegetation.
What is required for Reduced Site Disturbance Credit 5.2?
Reduce the development footprint to exceed the local zoning’s open space requirement for the site by 25%. For areas that have no local zoning requirements designate open space area adjacent to the building that is equal to the development footprint.
What is SS Credit 6 called?
Storm water Management
What is the intent of the Storm water Management Credit?
Limit disruption and pollution of natural water flows by managing storm water runoff.
How many points are available for Storm water Management?
Two
What is required for Storm water Management Credit 6.1- if existing imperviousness is less than or equal to 50%?
Implement a storm water management plan that prevents the post-development 1.5 year, 24 hour peak discharge rate from exceeding the predevelopment 1.5 year 24 hour peak rate.
What is required for Storm water Management Credit 6.1- if existing imperviousness is greater than 50%?
Implement a storm water management plan that results in a 25% decrease in the rate and quantity of storm water runoff.
In Storm water Management credit 6.1, what are potential strategies for managing storm water flows
Design the project site to maintain natural storm water flows by promoting infiltration. Specify garden roofs and pervious paving to minimize impervious surfaces. Reuse storm water volumes generated for non- potable uses such as landscape irrigation.
What is required for Storm water Management Credit 6.2?
Remove 80% of the average annual post development total suspended solids (TSS) and 40% of the average annual post- development of total phosphorous (TP)
What document describes the practices to be used to reduce storm water TSS and TP?
EPA’s Guidance Specifying Management Measures for Sources of Non-Point Pollution in Coastal Waters, January 1993 (Document #EPA 840-B-92-002)
What is SS Credit 7 called?
