Permit Guide Procedures
Storm Water Management & Erosion Control Permits
WHEN: Proposed land development activity in unincorporated areas that will expose soil to erosion (grading or filling) or increase storm water runoff (add rooftops & pavement) and meets any of the following permit thresholds:
WHY: To minimize water pollution, flooding, and other negative impacts of urbanization on downstream water resources (lakes, streams, wetlands & groundwater) and property owners. Aimed to control soil erosion and sedimentation during construction and manage the discharge of storm water after development. Pursuant to Waukesha County Code Chapter 14 – Article VIII – Storm Water Management and Erosion Control.
WHO: The Waukesha County Department of Parks and Land Use - Land Resources Division issues permits.
HOW: To obtain a permit, the applicant must prepare erosion control and/or storm water management plans, as noted above. The contents of these plans depend on the size and complexity of the site. For erosion control plans on sites one acre or less, a short checklist of plan requirements is on the application form. For all storm water management plans and erosion control plans for larger sites, published checklists and other technical guidelines are available. A submittal must include the following documents (available here):
New land divisions that meet any of the triggers listed above for storm water management plans are required to obtain a Preliminary Review Letter prior to asking for action on a preliminary plat or other zoning approvals. Obtaining conceptual/general review comments on these plans will help facilitate other plan review and approval processes. It also allows the applicant to proceed through those processes without committing the resources needed to complete final engineering designs and construction plans or line up contractors, which are all needed to obtain a permit. Certification of compliance (see checklist 4) with this ordinance is also required before recording new land divisions at the Waukesha County Register of Deeds.
