Impacts tables to be updated following comments receveid at CP4C permit review mee�ng General Comments: i. Tim Love, the new Hanover County Engineer, provided the following comments a�er the CP4C mee�ng to NCDOT on Tuesday October 24, 2023 a. The New Hanover County Planning Department is currently under contract with a consultant to evaluate flood mapping in the northern watersheds of the County. One of these areas is Island Creek in the vicinity of where this project �es into the I-140 7 | Page R-3300A CP4C Mee�ng – 10/18/2023 interchange. I believe Site 7 and Site 8 are in the area referenced. Please coordinate with NHC Planning regarding the �ming, scope, etc. of this study and consider incorpora�on of the study findings into design considera�ons for the crossing at Site 7 and the fill adjacent to the stream at Site 8. b. By rough approxima�on, there is approximately 1,500 acres of undeveloped land in New Hanover County upstream of this project. While the NHC stormwater ordinance does require pre- and post- atenua�on of stormwater from development, that is for the 25- year design frequency. If the 50-year or higher design frequency is u�lized for the bridge and culvert crossings in line with NCDOT 2022 Drainage guidelines and given the design life of these structures typically being 50+ years, if not already accounted for, please consider a future development scenario for this upstream area that would align with an�cipated uses iden�fied in the NHC comprehensive plan and consider accoun�ng for that with the hydraulic design of the bridges and culverts. If a 50-year design frequency is used, please provide NHC with calculated 100-year water surface eleva�ons for use in future planning considera�ons.
