in C.F.S.
A 19-minute time of concentration was used for the runoff calculations for existing
conditions. A 23-minute time of concentration was used for the runoff calculations for the
proposed conditions. The calculations include a fully developed adjacent lot draining
through a drainage easement to the rear yard drain.
Conclusions
More than sufficient capacity will exist in the system to handle a 10 year+ storm.
Introduction
The subject of this drainage study is approximately 1.4± acres located on the
south west side of Commerce Way in South Windsor, Connecticut.
Under existing conditions, the site drains to the north west side of the property.
The proposed improvements to the site include the construction of a
Office/warehouse with parking for 16 vehicles, and a storm water management system.
Collection of storm water will be through a series of catch basins to be connected to an
existing drainage pipe adjacent to the property. An existing catchbasin will be changed to
manhole at the rear of the property and a doghouse manhole will be added along the
common driveway between properties. Storm water detention is provided by a common
detention area which is part of the Industrial park.
Methodology
Both the Rational & SCS method were used to determine 2, 10, 25, 50 and 100
year storm discharges for pre-existing. The rational method was used proposed
conditions.
Triangular hydrographs were generated and flood routed through the designed
detention basin and storage by the use of the Storage Indication Method of flood routing.

MEMORANDUM

From: Jeffrey H. Folger-Zoning/Wetland Enforcement Officer
Date: April 13, 1999
Re: Appl#99-45P E&S Review of the proposed Finnegan Electric Inc. industrial site,
Plans dated 6/16/99.
The project is to construct an 6600sgft industrial building on 30,000sgft located at
Commerce Way.
Site: The site is located in the Scantic River watershed. The parcel is comprised of 1.5
acres. Currently the site is open and grassed.
There are no wetlands on the site or 40 feet from the property boundaries. The site is
comprised of medium and fine sands overlaying silts and clays. Erosion potential is
expected to be low because the site is level. Planned erosion controls appear to be
adequate for the project.
Stormwater is planned to be controlled by catchbasins and pipes to an existing drainage
pipe into the existing detention basin serving the entire street. Two sediment chambers
are planned to capture sediment and floatables. The two catchbasins located in the
driveway are proposed to have 4' sumps.
