HomeMy WebLinkAboutHamilton County Surveyor's Review Letter May 10, 2016 Weihe Engineers ATTN: Eric Carter 10505 North College Avenue Indianapolis, IN 46280 VIA E-MAIL: CarterE@weihe.net RE: Horse Barn & Riding Center Dear Mr. Carter, We have reviewed the construction plans submitted to the Hamilton County Surveyor’s Office on April 22, 2016, for this project and have the following comments: 1. The proposed project falls in the incorporated area and MS4 jurisdiction of the City of Carmel. 2. The proposed project DOES NOT fall in a Carmel Wellhead Protection Zone. 3. The proposed project falls in the Little Eagle Creek Watershed. 4. Please submit an outlet permit for the indirect discharge to the Bear Creek Arm of Little Eagle Creek Regulated Drain. The application is available at Surveyor's Form Page. 5. For determining the allowable release rates, the post developed shed should stop at the future 146th Street ROW line, as it will have its own stormwater conveyance and detention system. The temporary situation until road improvements are complete can route the water through the pond and pass it through as off-site during the large storm events. 6. The open channel across this parcel to Shelborne Road is natural stream, with maintenance being the responsibility of the property owner. The owner could petition for it to become part of the Bear Creek Arm of Little Eagle Creek Regulated Drain, which would provide for maintenance to be covered from the watershed maintenance fund that all benefited users pay into. 7. Please submitted revised construction plans/drainage calculations once all TAC comments are addressed. Should you have any questions, I can be reached at 317-776-8495. Sincerely, Greg Hoyes, AC, CFM, CPESC Plan Reviewer CC: Angie Conn – Carmel DOCS John Thomas – Carmel Engineering Dave Barnes – Carmel Engineering Greg Ilko – Crossroad Engineers
