• Narrative
Introduction
The project site is located at the southeast corner of intersection of 106th Street
and Commerce Drive in Carmel, Indiana, and is bounded by 106th Street on the
north, by a commercial building to the south, by future development to the east
and Commerce Drive to the west. The site is not within the 100-year flood zone
per Flood Insurance Rate map 180081 Panel 0205, Map Number 18057C0205F
effective February 19, 2003.
Description
This project consists of the construction of a proposed bank building and
associated parking. areas and landscaped areas. Additional project activities
include the construction of a proposed storm sewer system.
Existing Site Description
The site is presently undeveloped. Under existing conditions, the project site
consists of grass. A soil map from United States Department of Agriculture Soil
Conservation Service identifies Crosby and Brookstone soils on the property.
Existing drainage characteristics are such that the site generally flows to the
existing swale on the north that eventually discharges into storm sewer system
within Commerce Drive.
Proposed Conditions
Proposed drainage for the developed site consists of a system of new storm
inlets and connecting pipes. The developed site will drain to the west into an
existing storm sewer system within Commerce Drive. The storm drainage system
along Commerce Drive was designed to accommodate the direct runoff from the
subject site. All new storm sewers are designed to accommodate a 10-year
storm event using the Rational Method.
. Calculations are included in this report.
• Based on the study prepared by American Consulting, Inc, the subject site has been
included as the area in the proposed condition that will flow to the existing culvert under
US 421 and into the Park Northwestern drainage system.
