The modification request is a result of roadway design changes which are necessary to service the proposed school. The following revised project information is included as part of this modification request: • Project Summary Sheet • Pre -Construction Notification Form • Project Site Figures o Figure 5 — Proposed Site Layout (2015 ESRI Aerial ) o Figure 6 — Impact Area (2015 ESRI World Imagery Aerial) • Permit Drawings for Iredell Charter Academy The revised project impacts will result in permanent impacts to 135 linear feet of an Unnamed Tributary to Kerr Branch (S1) from the replacement of an existing 41 If, 48" CMP culvert crossing at Crosstie Road with proposed 118 If of twin 60" RCP culverts. Non- erosive design criteria will be met from the installation of 2-15 If rip -rap aprons (30 If of permanent impacts) at the inlet and outlet of the proposed culvert. The rip -rap aprons will be installed so that the finished elevation of the rip -rap does not exceed that of the original stream bed. The project requires 60 linear feet of temporary stream impacts to install impervious dikes, stone rings, and a pumped bypass to allow work in dry conditions.

A low density residential area is located south of the project area. 3b. List the total estimated acreage of all existing wetlands on the property: 0 acres 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: —1,260 If 3d. Explain the purpose of the proposed project: The project seeks to construct a charter school on a 34 -acre property that would accommodate over 1,000 elementary and middle school students at full enrollment. Offsite roadway improvements are necessary in order to service the new school including the construction of a round -a -bout along US21/NC 115. New location roadway is proposed to serve as the main entrance in to the school. 3e. Describe the overall project in detail, including the type of equipment to be used: The project will result in permanent impacts to 135 linear feet of an Unnamed Tributary to Kerr Branch (S1) from the replacement of an existing 41 If, 48" CMP culvert crossing at Crosstie Road with proposed 118 If of twin 60" RCP culverts.

Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. An earlier proposed roundabout along US Hwy 21 was removed, avoiding the need to extend an existing culvert which would have resulted in additional permanent impacts. The sidewalk along the entrance into the school was designed to the minimum width required to minimize impacts to the stream channel during and post -construction. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The project is utilizing new impervious area but accompanied with proper sedimentation basins and ponds for water quality considerations within project footprint. The side -slopes are at a maximum of 2:1 where appropriate to minimize stream impacts. Temporary construction impacts will be limited by the installation of stone rings an impervious dike for temporary stream diversion as well as restoring/stabilizing when construction is complete. 2.
