Ward; Samuel Clark Cc:Nola Albrecht; Erik Dirks; Keith Buck; Karen Valiquett Subject:North End Drain, notes, 4.21.20 Attachments:North End Townhomes (AKA Smokey Row)--Review Letter.pdf     Thanks again for your time today. I am providing an overview of what we discussed below. If you find I have overlooked any expectations, please feel free to respond.   Aim: refresh on North End comments and coordinate approach to PP, SP, and subsequent ADLS filings in relation to "blueline" or "ditch" where Hamilton County Surveyors are looking to take jurisdiction.   Focus: Spirit of North End is taking LOTS of time and effort to preserve topo and trees and setting buildings into spots as minimally invasive to natural topo possible. Seeking coordination on: General direction as design team and HamCO expectations for timing to take drain and what looks like and how we impose impact at Phase 1 and 2. *Because Old Town and Erik specifically is working on creative storm water solutions, already in Corp of Engineers process, and coordinating with Kashman (drain currently in Carmel jurisdiction), the agreed upon next steps are to: 1) allow Erik/Old Town to still work to make stormwater plan more affordable, as what we are doing with the blueline is currently unknown. (see attached image); while honoring Kent/Ham Co Surveyor's main goal to keep the water flowing.     2) Keith/Shrewsberry need to follow up on flood plain study for Hunter's Knoll Drain, (double check drainage report). As Kent identified this as standard and in ordinance: from 31 to Cool Creek tributary, must have some flood study on that area; need hydraulic study of blue line (confirm if there is flood plain associated with the blue line)    3) Erik/Old Town need to note that as we get into SP, if any trees fall across then OT clears, also DO NOT use "Tree Preservation area" in wording, as this makes it difficult for Ham Co Surveyor if future issues.     4) Erik/OT & Keith/ Shrewsberry still working out plan for NE of lot 60, possible encapsulation of short section    Kent clarified:   1) not talking about clear cutting  2) (OT operating currently off of city easement requirements) Kent clarified statutory easement 75 feet from center line of enclosed structure from both sides if open then 75 from top of bank (can be 150'); statute lets you go down to 15’ on tile/storm system and 25’ on open ditch, but doesn’t give any room for maintenance on open ditch (ie people put fences right up to it). Therefore open ditch is 35’ minimum from top of bank; down to 15’ on pipe depending on size of pipe, so 15’ on edges of pipe.  Future preparation needed from Shrewsberry: 1) Consider the encapsulation section and modified easement width that both Kent and Jeremy are happy with because at end of Phase 2/Phase 3, Old Town intends to petition for HamCo jurisdiction.    2) Note in writing on Project Dox that #4 (see attached letter) will happen in Phase 2 and will respond pending approval (go ahead with Phase 1 without it being regulated AS LONG As we have easements needed and any comments on plans about debris clean up identified)   CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender  and know the content is safe.   2     .       Rebecca McGuckin   Community Collaborator  To help protect your privacy, Microsoft Office prevented automatic download of this picture from the Internet.  (317) 496-7160  URVCYWS OFF fanN It It 4V rJ I t xenton C. `Ward, C"FM Suite 16S Surveyor of Xamitton County One Namilton County Square T6one (3�7) 776-9495 ,Noblesville, Indiana 46o6o-2230 `Fax (317) 796-9629 Shrewsberry &Associates 7321 Shadeland Station Indianapolis, IN 46256 RE: North End Townhomes We have reviewed the construction plans submitted to the Hamilton County Surveyor's Office on December 5, 2019, for this project and have the following comments: 1. The project falls in the incorporated area and MS4 jurisdiction of the City of Carmel. 2. The proposed project DOES fall in a Carmel Wellhead Protection Zone, 3. The proposed project falls in the Cool Creek Regulated Drain Watershed. 4. This project's drainage system is to be county regulated as well as the existing waterway running through the subdivision per preliminary discussions and will require the following procedural items: Petition for regulated drain subdivision, subdivision outlet permit for the indirect discharge to the Cool Creek Regulated Drain, engineer's estimate, and all associated bonds for 120% of construction cost. 5. Site plan must accommodate the statutory easement of 75 feet from the top of bank on each side of the Hunters Knoll open drain. As of now, site plan does not display any easements for the Hunters knoll open drain. 6. Access to the waterway must be provided within designated common areas. This must be called out on the plat. 7, BMPs cannot limit the maintenance, use and access of regulated drain easements. 8. The Hunter's Knoll Open Drain must be improved to county standards. This will include the clearing of trees for the purpose of easement access. 9. The 10-year storm event will need to remain within the banks of the Hunter's Knoll open drain for both the upstream watershed and the on -site flow. 10. Please show the crossing of the Hunter's Knoll drain on sheet 2.1 including the cover. 11. The outfall from the US-31 pipe will need to be stabilized. Please verify whether there is a significant grade drop out of the structure. 12. Structure 601 needs to be stabilized per HCSO design standards (0-5). Please provide this construction detail. 13. The pedestrian crossing "L" over the Hunter's Knoll drain will need to pass the 100 year storm event with no reduction in velocity. 14. Please provide updated drainage calculations when they become available. 15. Please provide updated construction plans/drainage calculations once all TAC comments have been addressed 16. Please note, additional comments may be warranted at a later date.
