Wake County requires the use of the Wake County Stormwater Hybrid Design Tool for all stormwater management submittals. Accurate use of this tool ensures compliance with the Neuse Nutrient Strategy (Neuse Rules), the Wake County UDO and the Falls Lake and Jordan Lake Rules. Tool calculations are based on a combination of the Falls/Jordan Nutrient Accounting Tool developed by the State for nutrient loading and a Wake County Design Tool previously prepared for Wake County by Withers and Ravenel (2006) for volume control. The purpose of the tool is to streamline the many different stormwater requirements and facilitate more timely review and approval of stormwater management plans. For each regulatory requirement, Wake County adheres to design standards readily accepted by the State of North Carolina. Please see the Wake County Stormwater Manual: Submittal and Design Guidance for complete stormwater requirements. Design of stormwater control measures shall be consistent with the State of NC Minimum Design Criteria.
Older versions of Excel will require the installation of a compatibility pack from Microsoft to ensure functionality. Please contact Ashley Rodgers (919-291-3893) if compatibility pack does not yield desired results.
