Stormwater Management Acceptance & Review Information
(Rezoning, Special Permit, Special Exception, & Development Plan Applications)
- Effective February 21, 2005, Land Development Services (LDS) will be the lead agency for the coordination of the Department of Public Works and Environmental Services' (DPWES) review of stormwater management issues on rezoning, special permit, special exception and development plan applications.
- Effective February 21, 2005, a checklist/sheet index form will be used to evaluate whether the required stormwater information has been incorporated on development plans and plats submitted in association with rezoning and special permit and special exception applications.
- Guidance for meeting the outfall submission requirements on rezoning, special permit, special exception and development plan applications.
Effective July 1, 2004, the submission requirements for rezoning, special permit, special exception and development plan applications were amended to require greater detail that addresses the design of stormwater management facilities and stormwater conveyance systems; and compliance with outfall requirements. Since that date, the Stormwater Planning Division (SWPD) of DPWES has taken the lead on coordinating DPWES' review of this information. To improve the consistency of comments and communication between the zoning and site plan processes, coordination of the DPWES review is being transferred to staff of the Environmental and Site Review Division (ESRD) of LDS. SWPD will continue to review the applications on a routine basis and will forward comments to ESRD. The Maintenance and Stormwater Management Division will review applications and supply comments to ESRD as warranted based on the specifics of the design. ESRD will compile the comments received into a single response to the Zoning Evaluation Division of the Department of Planning and Zoning, and will represent DPWES at meetings and public hearings as needed.
To facilitate both the timely acceptance of rezoning, special permit, special exception and development plan applications and DPWES' review of the stormwater information, applicants are requested to incorporate (i.e. "sticky back") the checklist entitled "Minimum Stormwater Information for Rezoning, Special Exception, Special Permit and Development Plan Applications" onto development plans and plats submitted with rezoning, special permit and special exception applications. The checklist, which includes the plan sheet numbers where the required information is located, will facilitate the acceptance of zoning applications and the review of the stormwater information by DPWES by ensuring that all required information is included and readily located on the submission.
As noted above, the recently adopted submission requirements for rezoning, special permit, special exception and development plan applications include the requirement for additional detail with respect to stormwater outfalls. Information is required with respect to the adequacy of downstream drainage, including the sufficiency of capacity; a narrative description of the existing outfall conditions through a specified distance downstream; and a narrative description of how the outfall requirements of the Public Facilities Manual (PFM) will be satisfied. In describing the existing outfall conditions, applicants must note the types of conveyance structure(s) existing/proposed throughout the required distance, and the existing condition of the conveyance structures, as well as noting if there will be a change in drainage area to the outfall as a result of the proposed development. For example, when the conveyance system is a natural channel, any erosion along the channel must be identified. With respect to the description of compliance with the PFM's outfall requirements, applicants must describe any improvements (e.g. channel stabilization, pipe replacement, etc.) that are necessary to achieve compliance.
