Project Description 3a- Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The site is an existing residential subdivision with paved streets and landscaped home sites. The undeveloped areas are a combination of landscaped open spaces and natural undeveloped areas with woody vegetation. The general land use is residential. . . ........ 3b.

List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 10,000 linear feet + 3d� Explain the purpose of the proposed project: Repair & replace an existing culvert on Westshore Drive on the UT to the Toxaway River and Lake Toxaway. 3e, Describe the overall project in detail, including the type of equipment to be used: This project is to install one (1) new 4'x4' concrete Intake Structure and connection pipe to serve the off-line water feature pond located adjacent to the main entrance to Lake Toxaway Estates. This portion of the work will be subject to the requirements of USACE NWP 39 and the applicable NCDENR Water Quality Certification as directed by the regulatory authorities. This project also includes replacement of Dineteen 19 existing culverts that are presently in use and serviceable structures. These existing culverts are deteriorating and require replacement. The culvert replacements are located along West Club Blvd. (also known as Westshore Drive on some Tax Maps and survey maps). Most of the culverts to be replaced are located in "dry ditches" that only carry stormwater runoff during storm events. However, several culverts are located in streams. SEE ATTACHED SHEET C-1 THROUGH C-5 FOR ADDITIONAL DISCRIP'TION. (NOTE— Pages 3, 5, and 8 of the original PCN have been revised to include one additional culvert replacement on Mills Creek Road, Lake Toxaway Estates, Lake Toxaway, NC.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The smallest length of culvert possible was selected to minimize impacts. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. This work is to replace nineteen 19 c L_1 existing culverts and install one (1) new 41x4' precast concrete Intake Structure. The existing culverts are in-place servicable structures that require replacement. The culvert replacement work will be limited to failing culverts only. No in-stream work outside of the culvert footprint will I be performed'. The existing culverts wil be replaced with like kind materials. The new culvert will be installed at the same grade as the original culvert.
