LID stormwater management requirements for construction projects are outlined in the Navy LID Policy (November 2007) and the Federal Energy Independence and Security Act (EISA) Section 438 (December 2007).

Navy LID Policy requirements Sets a goal of No Net Increase in SW volume and sediment/nutrient loading

This applies to major renovation projects (Greater than $5 Million) and construction projects (Greater than $750 Thousand)

Directs that LID be considered for all projects that require stormwater management.

EISA Section 438 requirements Applies to all Federal facility development and redevelopment projects with a footprint that exceeds 5,000 square feet.

The predevelopment hydrology of the property must be maintained post-construction with regard to temperature, rate, volume, and duration of flow

To accomplish this, Navy and A/E designers should use LID site planning, design, construction, and maintenance strategies to the Maximum Extent Technically Feasible.
