RE: LEO at Carmel, Carmel Wavier Requests
Mr. Kashman:
Advenir Oakley Development, LLC is proposing to develop a multi-family housing development
on a 30.74+ parcel that is a part of the overall Legacy Development. The proposed development
is located on the south side of 146th Street and west side of Community Drive in Carmel,
Indiana. Currently the tract has been previously graded as a part of the Legacy project and has
since been covered with unmaintained trees and tall grass, with smaller portions of maintained
grass. The project site is adjoined by multi-family residential and single-family residential
properties to the north, multi-family residential and commercial properties to the east and south,
and single-family residential properties to the west. Existing stormwater drains south to the
existing storm sewer system in the adjacent multi-family development Windward at Legacy.
Weihe Engineers requests a wavier from standards for less than 2.5-feet of pipe cover in short
isolated areas near gutter lines of the street. The storm sewers downstream of these areas
have been designed at the lowest elevations possible to maximize the cover in these areas.
The lowest amount of cover under a paved area for these areas is 2.22’. Additionally, in
accordance with Carmel standards, the hydraulic modeling demonstrates that the hydraulic
grade line will not exceed the top-of-castings of the existing storm structures. We have worked
with Crossroads to address all other comments regarding the existing storm sewers.
If you have any further questions or requests for additional information pertaining to this project
review, please contact me at 317-846-6611.
Thank you,
Rick Ellis
Project Manager, Residential Development
