The purpose and need for the Project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality. This project is located in Charlotte, North Carolina, just east of downtown along an unnamed tributary to Little Sugar Creek (Project Vicinity Map, enclosed). CMSWS is hereby submitting an addendum to the aforementioned re -authorization request in an effort to provide more accurate and complete information. A Jurisdictional Determination and Nationwide Permit (Action ID 2011-00366) were issued for this project by Ms. Amanda Jones on March 2, 2011. Ms. Coleen Sullins issued Water Quality Certifications (DWQ No. 11-0022) for the project on January 13, 2011. The project was delayed in order to allow time to update the plans to meet new design standards from various agencies and City Departments. This included updated NCDOT standards, updated and new City of Charlotte storm water and stream restoration details and standards, and new CDOT handicap accessibility standards. With each update of standards there were delays for negotiating design fees, field surveys, plan revisions, and subsequent City reviews. Both the jurisdictional determination and the nationwide permits expired during this lengthy construction plan update process. Proposed impacts remain unchanged from the originally permitted impacts. Project impacts are proposed to perennial RPW streams and include pipe extension, placement of plunge pools and rip rap energy dissipaters, longitudinal channel adjustments to accommodate pipe system upgrades, and stream enhancement activities. Proposed project impacts are illustrated in the newly annotated Louise Avenue CIP Construction Plans (enclosed) and overall project area map and are summarized in Table 1 below. As additional clarifying information, the existing culvert under Louise Avenue is shown as buried 1 foot on the construction plans from that culvert installation; therefore, the extension of this culvert will be constructed to match the existing elevation of the culvert. If the culvert was originally installed correctly, the extension should also be buried 1 foot to allow for aquatic life passage. The step -pool sequence described as impact S2 is proposed to have a maximum drop of 12" to the water surface elevation at any point. This can be seen in the attached permitting plan set on detail sheet 2R. To report pollution or drainage problems, call: 311 � http://stormwater.charmeck.org '`l' CHAMOTTE Table 1.

As such, the revised Louise Avenue CIP mitigation plan consists of purchasing 198 SMUs from the City of Charlotte Umbrella Mitigation Bank to offset permanent impacts of 198 linear feet (1:1 ratio confirmed by Ms. Amschler on 7/19/16). 42 SMUs will be purchased to offset permanent impacts associated with the Siegle Avenue Culvert Replacement project (USACE Action ID: 2009-00680) and 156 SMUs will be purchased to offset the permanent impacts associated with the Louise Avenue CIP. CMSWS respectfully requests re -authorization of the project under the USACE Wilmington District's nationwide permit program. Potential adverse water quality impacts associated with construction storm water runoff will be managed in accordance with NCDENR NPDES General Construction Storm water Permit, NCGO1000, and the City's PCCO requirements. I appreciate your prompt attention to this request. If you have any questions regarding this request please do not hesitate to contact me at (704) 336-3927 or erin.tumer@ci.charlotte.nc.us.
