The drainage area to the stream crossing is approximately is 594.5 acres. Adequate ditches and cross culverts will be provided throughout the site to convey stormwater run off to the box culvert. At the point of discharge of the box culvert, the contribution from our site area is less than 1% of the drainage area and will not have an impact on peak flows in the existing stream. CHANNEL PROTECTION The project area is less than 1;,'�O' of the total drainage area of 594.5 acres. The project area has been laid with ditch stabilization matting as well as English ivy being provided on the slopes greater than 3:1 for slope stabilization. Adequately siiized culverts are being provided to convey water from the channel. By the time storm water runoff reaches the culvert it will have a negligible effect on downstream properties. QUALITY: Scope of this project is the development of a stream crossing driveway for a singe house on an 88 acre rural site. While there is no intention to clear massive wooded areas or to fundamentally alter the property as it exists today, we do understand the potential for- change in land use must be anticipated in completion of the run off reduction removal spreadsheet. We have developed an applicable area representing a portion of the property associated with this project of 4.15 acres. This area represents the areas within the stream buffer that are currently wooded. This area is already recognized as conserved due to the fact that it is within the stream buffer and will continue to be undisturbed by activities on the property. We have performed the computations and found that no treatment of storm water run off is required based on the Runoff Reduction Removal spreadsheet.
