EROSION CONTROL & STORM WATER MANAGEMENT

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:

4,000 square feet land disturbance (grading/structures)
400 cubic yards of excavation, fill or a combination of these
Disturbs a slope of 20% or greater
300 lineal ft. of new utility or other open channel disturbance (unless utility is plowed in outside of ditch line)
All new "SUBDIVISIONS" (as defined by local codes)
All sites where at least 1/2 acre of impervious surface is added to the landscape (rooftops, pavement, etc.)
Other sites, regardless of size that the Land Conservation Division determines is likely to cause an adverse impact to an environmentally sensitive area or other property (may require erosion control and/or storm water management plan)

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 Eau Claire County Code Chapter 17.05 – Storm Water Management and Erosion Control

WHO:
The Eau Claire County Department of Planning and Development – Land Conservation Division issues permits. Department is located at 227 1st Street West, Altoona, WI 54720, phone 715-839-6226.

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:

Signed Application
Permit Fee
Site Map
Erosion Control Plan
Storm Water Management Plan
Narrative/support materials explaining plan contents & designs, construction sequence, etc.
Other applicable items, such as a storm water facility Maintenance Agreement or Performance Bond

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 with this ordinance is also required before recording new land divisions at the Eau Claire County Register of Deeds.

VARIANCE OR APPEAL:
An appeal of a decision by the Land Conservation Division staff must be made in writing and submitted to the Board of Land Use Appeals within 30 days of the date of decision.

TIME:

Staff must approve or deny applications within 20 days
If staff requests additional information, the 20-day time line will start again when the Department receives the new information.
