Stormwater Management Regulations and Requirements

The video tutorial covers the district's stormwater management regulations, focusing on two main types of regulated activities: major land disturbing activities and major substantial improvement activities. It explains the requirements for projects in the Anacostia Waterfront Development Zone (AWDZ) and introduces key concepts such as Stormwater Retention Volume (SWRV) and Off-Site Retention Volume (Off V). The tutorial also discusses the Stormwater Retention Credit (SRC) system, detailing how projects can use SRCs based on their location and compliance with SWRV requirements.

What are the two main types of activities that trigger the stormwater rule?

• Minor land disturbing activities and minor improvements

• Residential gardening and small-scale landscaping

• Commercial building maintenance and repair

• Major land disturbing activities and major substantial improvements

What is the minimum land disturbance size that classifies an activity as a major land disturbing activity?

• 7500 square feet

• 1000 square feet

• 2500 square feet

• 5000 square feet

Which of the following is a requirement for major substantial improvement activities?

• The project must be located in a residential area

• The cost must exceed 50% of the pre-project value of the structure

• The project must involve new construction only

• The project must be completed within one year

What are the two conditions for a project to be considered an AWDZ project?

• Located in a residential area and funded by the federal government

• Located in a commercial zone and funded by a private entity

• Located within the highlighted area and funded by the district government

• Located in a rural area and funded by a non-profit organization

What does SWRV stand for in stormwater management?

• Stormwater Reduction Variable

• Stormwater Regulation Value

• Stormwater Resource Verification

• Stormwater Retention Volume

What is the purpose of off-site retention volume (Off V)?

• To increase the amount of stormwater on-site

• To eliminate the need for on-site infrastructure

• To meet SWRV requirements through off-site solutions

• To reduce the cost of stormwater management

How can projects comply with their SWRV requirements?

• By using off-site retention volume or on-site solutions

• By increasing the project size

• By ignoring the SWRV requirements

• By using only on-site green infrastructure

What is required for AWDZ sites when using SRCs?

• They must use SRCs from any available source

• They must use SRCs from the MS4

• They must use SRCs from the CSS

• They must use SRCs from private vendors

What happens if SRCs are not from the Anacostia Watershed for AWDZ projects?

• They can be used without any additional requirements

• They must be approved by the federal government

• They need to use 1.25 times more SRCs

• They are not allowed to be used

What is the requirement for projects in the MS4 regarding SRCs?

• They are exempt from using SRCs

• They can use any SRCs available

• They must use MS4 SRCs regardless of on-site retention

• They must use CSS SRCs
