Big Branch Project #12 -0724, Issue Date August 27, 2012 Dear Ms Higgins The Clay of Raleigh had submitted the above referenced three projects that are a part of the City's Petition Program and obtained permits for each project in 2012 We discussed the permits in February with Mr David Schaffer of the US Army Corps of Engineers and he informed us that the permits will be expiring prior to completion of construction and that a resubmittal of the document would be required so that the permits could be re- issued A subsequent phone call to DWR staff confirmed that because the COE permit was required to be resubmitted that resubmittal to re -issue the 401 Permit would also be required The petition program gives City of Raleigh residents the opportunity to petition the City to qualify for design and construction assistance for repairs or improvements due to structural flooding or severe erosion The City had maintained an on -call contractor to perform the construction for these projects The construction contractor's contract with the City expired and the City had to place a hold on completing construction projects for the petition program In an effort to get the projects built soon, the City has decided to bundle several of these petition projects together and put them out for public bid so that construction can begin in the fall of 2014 The attached three projects are a part of this first bundle of projects Construction is anticipated to be completed on all projects in the summer of 2015 Please find attached five copies of the PCN which have been updated to the new PCN form. No changes have been made to the construction plans or attached documentation from the original PCN submittal.

Property Identification Number 520 Lakestone Drive: 1705481885 524 Lakestone Drive: 1705397030 1c Property Size: 520 Lakestone Drive: 0.64 acres 524 Lakestone Drive: 2.87 acres 3a. Existing Conditions The project is located in a well - established residential area of Raleigh, NC and consists of two properties 524 Lakestone a 0.64 acre parcel and 520 Lakestone a 2.875 acre parcel. The watershed for this project is fully developed with single family residences. The size and age of the house on this lot is typical of the majority of the residential development in this area which was built in the late 1970's. Five lots were subdivided around 2005 in which single family residences were built on three of the five 1/3 acre lots which has increased the stormwater runoff directly uphill from the residence at 524 Lakestone Drive. The increased impervious area and lack of sufficient storm drainage inlets within the right of way has caused stormwater to enter the combined driveway for 520 and 524 Lakestone Drive with a greater frequency. The only curb inlet is located at the lower end of the driveway at the street and therefore water for a majority of storm events does not enter the storm system. The stormwater overtops the combined driveway for 520 and 524 Lakestone Drive and flows down the driveway and towards the back of the house structure located at 524. An existing 18 inch RCP pipe currently collects and conveys the stormwater collected in the street to a stream located in the rear yard of the property. The pipe discharges into a small ditch that connects to the stream. An existing 15 inch RCP pipe is located under the existing driveway for 520 Lakestone. The outlet from the pipe to the stream is severely eroded. Additionally the stream right bank as viewed looking downstream is also experiencing severe erosion and has a lack of vegetation. Storm water from the piped system is currently entering the stream at a 90 degree angle to flow. This direction of discharge is contributing to the right bank erosion. 3b. List the total estimated acreage of all existing wetlands on the property: No wetlands area located at the end of the pipe and within the limits of disturbance. 3d. Explain the purpose of the proiect. The purpose of the project is to minimize the stormwater flooding at the property located at 524 Lakestone Drive, realign and stabilize the pipe system outlet, increase pipe capacity and provide additional stormwater access to the system with the installation of an additional inlet, and the reshaping, matting, and vegetative stabilization of the stream banks. The improved system will provide for better pipe capacity and stormwater collection, reduce flooding issues, stabilize stream bank erosion, and re- introduce woody vegetation into the stream bank and buffer through herbaceous and woody plantings. 3e. Describe the overall proiect in detail including the type of equipment to be used The project will consist of the addition of storm drainage infrastructure in the street right of way, an existing storm drainage pipe replacement with a larger pipe, drainage outlet channel improvements and stream bank stabilization. To provide better collection of stormwater at the street a new inlet has been designed on the uphill side of the driveway to collect stormwater before it crosses the driveway. The driveway will also be re- graded to direct water to the natural area and away from the structure. The existing 18 inch pipe is currently under sized to handle the design storm capacity. The existing 18 inch pipe will be replaced with a 24 inch pipe and angled to discharge into the existing stream at a better angle within the existing storm drainage easement ending at the approximate distance away from the stream as the original pipe. The existing pipe will be removed except for two locations in which the existing pipe is too close to an existing structure for removal or is underneath the existing asphalt driveway. The storm drainage ditch from the pipe outlet to the channel will be graded and protected with riprap to prevent erosion. The existing stream banks will be graded back to a 2H: 1V slope and stabilized with herbaceous and woody vegetation. Rock toe protection is planned around the pipe outlets and where turbulent flow is expected that may cause bank de- stabilization The rock toe stabilization will be placed only at the toe of the stream and will extend up the bank to a distance no higher than two feet. The stream bank will be seeded with an herbaceous mix of native grasses and matted with a biodegradable matting Woody vegetation in the form of rooted plant plugs will be installed for long term stabilization on the stream banks and will be added to the graded areas in the buffer as shown on the planting plan. The equipment to be used in this project is earth moving equipment and various other support apparatus. Heavy equipment may include hydraulic excavator, compactors, bulldozers, skidsteer loaders, and material hauling apparatus such as a dump truck This type of equipment will be used for excavation and placement of materials for the project. The construction equipment will enter off Lakestone Drive at the project property. The construction equipment will not enter or cross the stream and will perform all construction activities from the top of the existing stream bank. C. Proposed Impacts Inventory 6i. Comments for Buffer Impacts The buffer impacts categorized as B1 will consist of temporary impacts to access the area for installation of the storm drainage pipe and improvements to the drainage channel. Areas disturbed during construction will be restored to match the existing vegetative cover and new woody vegetation will be introduced. The buffer impacts categorized as B2 are impacts that will be for the pipe and stream stabilization The improved drainage channel and stream bank will be seeded to establish a stable, non - erosive channel for stormwater conveyance and enhanced with woody vegetation. D. Impact Justification and Mitigation 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project This project is necessary to aleviate flooding issues from an existing public storm drainage system that is under capacity. The project has minimized the impacts with the realignment of the existing pipe system and drainage outlet channel to provide a better flow into the channel that will reduce erosion. The proposed pipe has been designed to discharge at the same distance from the stream as the existing pipe. The proposed design will include bank stabilization and revegetation of the stream banks and buffers. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The proposed construction will minimize potential impacts by performing the construction from the top of the channel within a limited area on either side of the proposed storm drainage pipe and drainage channel. No equipment will be permitted to cross the stream. Native vegetation will be utilized for the herbaceous seed mix and rooted plant plugs that will be installed to stabilize the stream and enhance the buffers.
