Integrated Streambank Stabilization— Project Overview Owner: Simeon& Heidi Wolf Location: SE of SE Sec 8,TO8N RO6E; Town of Mazomanie I. Site Description The site is a farmstead and adjacent agricultural row crop fields and forested areas located in the Town of Mazomanie on directly adjacent Black Earth Creek. II. Project Description The landowners are proposing to address streambank erosion that is occurring on their farmstead and agricultural fields. The landowners are proposing to install bank stabilization in four areas where erosion is affecting their property. They are proposing to stabilize the banks by placing rock riprap one to two feet above the Ordinary High Water Mark(OWHM) and seeding grasses and forbs above the OHWM. This streambank stabilization project is designed and will be constructed under the NRCS Standard 580 for shoreline and streambank protection Hydrologic & Hydraulic computations have been performed on the watershed and the proposed design is stable for flows up to the 100 year flood event. III. Description of Activities A. General 1. The contractor shall notify Digger Hotline (800-242-8511) a minimum of 72 hours prior to any excavation at the site. 2. The contractor shall notify the LCD a minimum of 72 hours prior to an excavation at the site. Seth Ebel(608) 516-2639 3. The Landowner shall notify the DNR the same day it is notified by the contractor that work is about to start at the site. B. Construction 1. Construction equipment will access the site from Hudson Road. Materials such as rock, seed,mulch,erosion control blanket,will be hauled onto the site. Access to the sites will be from the gravel farmstead driveway. 2. Tree removal and grubbing of stumps will be required in along the area where riprap is proposed. Stumps and trees located outside this area will not be removed. 3. Erosion control will be accomplished by staging this project into four sections. All the work on one section of rock riprap including seeding and mulching will be completed before moving on to the next section of riprap. 4. All sections of rock riprap construction will be completed within 1 week weather permitting. For each section: a. Remove undesirable trees and stumps. b. Shape the bank to a 2:1 slope or flatter. Spoil will be placed outside the wetland and wetland indicator areas as defined in the construction plan and spread 3 to 6 inches thick in pasture or row crop fields. Wetlands are present adjacent to the most upstream site.
