Improve the quality of surface water and groundwater, protect natural habitats and manage water naturally during rainfall events.
Design the community on land without jurisdictional or non-jurisdictional wetlands.
Protect 100% on-site jurisdictional and non-jurisdictional wetlands from all construction activity.
If wetlands are disturbed, obtain at least 2 points under Advanced Stormwater Quality credit (Water Management Section)
Adhere to the following requirements:
Jurisdictional: Do not disturb by fill, discharge or drain more than 10% of jurisdictional wetlands on site. Disturbance can be allowed for installation of infrastructure only; not to create buildable area. Follow federal law for mitigation acreage and protocol.
Non Jurisdictional: Non-jurisdictional, isolated wetlands must be mitigated in a ratio of 1:1 in compliance with the following protocol (in order of priority):
- If it is impractical to mitigate on site, the project should mitigate off-site within the same watershed. The project team must demonstrate why it is impractical to mitigate on site.
- If it is impractical to mitigate off-site within the same watershed, the project must purchase land from a land trust or credits from a mitigation bank.
Any acreage created for mitigation of wetland impacts is not awarded ECC credit under other criteria or requirements.
- Wetland delineation map.
- Grading plans or erosion and sedimentation control plans clearly identifying protection fencing around all wetlands and buffers.
- Narrative explaining why wetlands must be disturbed.
- If the project is mitigating off-site, provide a map that indicates the mitigated area is within the same watershed.
- If the project is working with a land trust or mitigation bank, provide proof of mitigation credit purchase.
