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)

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.
Should you have any questions, I can be reached at samuel.dark@hamiltoncounty.in.gov

2. Name of all receiving waters
If the discharge is to a municipal separate storm sewer, identify the ultimate receiving water
3. Estimate of peak discharge for post construction conditions (10-year)
4. Locations of specific points where stormwater discharge will leave the site.
5. Locations where stormwater may be directly discharged into groundwater, such as abandoned
wells or sinkholes

Good afternoon,
I have attached the secondary plat application. You will note that the legal description is not attached. We are
awaiting Cripe's response and still expect it this afternoon. Per Alexia's reply to Keith, I am sending this to you
now in hopes of still receiving a docket number today.
Know you are all in training, so I understand if it doesn't work out for you to assign it before end of business.
Thank you,
