This credit reduces stormwater management requirements in developments that support a strategy of watershed zoning by locating in subwatersheds that are designated as non-supporting. A similar credit could be applied to any development within targeted growth areas.
|Watershed Zoning: Summary|
|Goals||Encourage development in degraded watersheds.|
|Stormwater Management Objectives||Water Quality/ Recharge||Discount based on existing watershed impervious cover, or do not require.|
|May not be required.|
A watershed Zoning Credit can be awarded to developments that meet the following criteria:
The achieved credits include:
Care needs to be taken when implementing a watershed zoning ordinance. In TMDL watersheds, reducing water quality requirements may result in a violation of water quality standards. Furthermore, the credit needs to ensure that new development does not impact a relatively high quality reach within the subwatershed, or cause local flooding.
Modifications to the pre-development curve number condition only apply in communities that require the assumption of a highly pervious land use, such as woods in good condition. The pre-developed curve number needs to be clearly defined to limit abuse of this credit.
