CEPSCI Post-Construction and Site Restoration

Question 1

What is 'permanent stabilization' in the context of post-construction erosion control?

Accepted Answer

Establishment of permanent vegetative cover or non-vegetative measures sufficient to prevent long-term erosion without ongoing maintenance

Answer

Permanent stabilization ensures that soil will be protected from erosion after construction is complete, typically through vegetation achieving at least 70% coverage per the NPDES CGP.

Question 2

What is a 'seed mix' and why is it important for post-construction stabilization?

Accepted Answer

A combination of grass and other plant species selected to provide rapid cover, erosion resistance, and long-term site compatibility

Answer

Selecting appropriate seed species for local climate, soil type, and site conditions ensures successful establishment and long-term erosion control without requiring ongoing reseeding.

Question 3

Which post-construction BMP is specifically designed to remove pollutants from stormwater before it discharges from a developed site?

Accepted Answer

A post-construction stormwater management facility such as a bioretention cell or wet pond

Answer

Post-construction stormwater management facilities (bioretention, extended detention basins, wet ponds) are designed to treat runoff from the completed development for the long term.

Question 4

What is 'bioretention' (rain garden) as a post-construction BMP?

Accepted Answer

A shallow, vegetated depression that captures and treats stormwater through filtration, infiltration, and plant uptake

Answer

Bioretention cells use engineered soil media and native plants to filter stormwater pollutants, reduce runoff volume through infiltration, and attenuate peak flows.

Question 5

What is the primary goal of restoring native vegetation on a post-construction site?

Accepted Answer

To establish a self-sustaining plant community that prevents erosion, supports biodiversity, and requires minimal long-term maintenance

Answer

Native vegetation is adapted to local climate and soils, establishing deep roots and dense canopy that provide superior erosion control, habitat value, and reduced maintenance needs.
