3. APPLICATION REVIEW
C-21-08: 908 Hartford Turnpike — Multifamily Development — Cohanzie Partners, LP. -
Applicant, Estate of Constance Rice - Owner, & Summer Hill Civil Engineers - Agent
Mike Ott, PE, Summer Hill Civil Engineers, Sagan Simko, Wetland Scientist, BL Companies,
Quandra Swayze, Harrison Consultants, Ron Penton, LaRosa Building Group, were present for
the applicant.
M. Ott reviewed the project location and the proposal to construct two buildings with a total of
40 rental apartment units and a community building.
S. Simko reviewed the wetlands in closest proximity to the development area. An un-named
perennial stream in the Jordan Brook watershed flows east to west. It has a man-made excavated
pond area and is identified as watercourse 1 in the wetland report. A forested wetland area is
hydraulically connected to the stream and is identified as wetland 1. Both the stream and
wetland have cobble and boulder substrates. There is another stream and wetland further south
on the property but it is well away from the proposed development.
M. Ott reviewed a site grading plan for the development with the 100 ft. upland review area and
50 ft. off-set from the wetland boundary highlighted. Activity within the upland review area is
limited to the eastern side of the development. He noted the limit of disturbance line has been
re-located closer to the limits of grading. A double row of silt fence has been added at the limit
of disturbance. He reviewed the proposed outlet location and design flow rates. The infiltration
basin will treat the water quality volume and provide the groundwater recharge volume on an
annual basis. The basin will be over-excavated and a sand, topsoil, compost mixture placed in
the basin bottom. Vertical riser pipes will direct flows exceeding the water quality volume to the
subsurface detention chambers.

p. 2 0f2
W. Thomas asked if the outlet could be relocated to the west side of the basin, further from the
wetland. M. Ott replied he does not think he can make it work elevation-wise.
W. Thomas asked if a hydro-dynamic separator unit was considered for the storm drain prior to
the infiltration basin and if isolater rows were going to be incorporated into the subsurface
chamber system. M. Ott noted he will be adding a forebay to the basin but will look into a
separator unit design as well.
R. Muckle requested written responses to staff's review comments and requested the engineer
review an alternative location for the outfall.
M. Ott reviewed the grading and sidewalk locations around the community building. The
proposed walking trail is an existing path, no improvements are proposed at this time.
Staff reviewed her written comments of August 9, 2021 with the Commission.
The Commission discussed whether the application requires a public hearing in accordance with
Section 9.1 of the wetland regulations.
Motion: Motion by D. Lersch, second by I. Plis that the proposed regulated activity does not
involve a significant impact or require a public hearing per Section 9.1 and does not require a
public hearing.
Vote: 7-0.
