STORMWATER DRAINAGE SUMMARY
Project: Auto Max Site Improvements
Location: 9728 N. Michigan Road, Carmel, IN 46032
Introduction
Block Properties, Inc. is proposing the redevelopment of a 1.19 acre lot into a commercial
automotive retail site located just north of the intersection of 97th Street and Michigan Road (US
421) in Carmel, Indiana, on the west side of Michigan Road. The existing commercial property
currently shares an access driveway from Michigan Road with the commercial property located
immediately to the north. The proposed site development for the property will continue to utilize this
shared access drive.
The improvements are approximately 0.79 acres and consist of paving a new interior access
driveway and associated parking to service an existing building being used as an automotive retail
shop. A portion of the site, approximately 0.40 acre to the west, currently exists as undeveloped
land and will remain in that state upon completion of this site development project.
Pre-Developed Conditions
Pre-developed land cover for the development watershed includes an asphalt driveway from
Michigan Road, two existing buildings, and some gravel and concrete parking areas. A portion of the
site, located at the far western end, is currently undeveloped.
The existing project site consists of six (6) different drainage watersheds. Runoff from the existing
northeast (EX NE) watershed flows via overland sheet flow to the east toward an existing inlet within
the Michigan Road right-of-way. Runoff from the existing southeast (EX SE) watershed flows via
overland sheet flow to the east toward another existing inlet within the Michigan Road right-of-way,
located immediately to the south of the first existing inlet. Runoff from the existing north central (EX
N) watershed flows via overland flow to the north of the existing concrete pad and sits there in a low
spot. Runoff from the existing south central (EX S) watershed flows via overland flow to the south of
the existing concrete pad and eventually is routed into an existing pond located offsite to the south
of the property. Runoff from the undeveloped existing northwest (EX NW) watershed flows via
overland sheet flow to the north. Runoff from the undeveloped existing southwest (EX SW)
watershed flows via overland sheet flow to the south.

South: Developed, Commercial

West: Undeveloped
Soil Types
Soils maps from the United States Department of Agriculture, Soil Conservation Service identify
Brookston and Crosby soils on the subject site. The soils predominantly are composed of Hydrologic
3
Groups B/D and C/D. When calculating curve numbers, the undrained condition was used for the
post-developed calculations.
Stormwater Management Design
Representatives from HWC Engineering met with representatives from the City of Carmel to
determine the required level of stormwater management for both quantity and quality. Because this
is a redevelopment project, the detention requirements for the proposed improvements are to detain
runoff from the 100-year post-developed condition to the 10-year existing condition of the site. This
storage will be provided within the stone base of two pervious asphalt pavement areas within the
proposed parking lot, as well as within a new bio-retention area which will be located immediately to
the east of the parking lot. Each of these areas occurs in series, and all will be connected via a
perforated HDPE underdrain to allow equalization within the pervious pavement stone for full storage
area utilization. The onsite detention system will ultimately outlet into an existing inlet within the
Michigan Road right-of-way, identified as STM. STR. #100 on the plan sheets.
The allowable release rate for the 100-year storm was determined by calculating the existing runoff
rate from the 10-year storm to STM. STR. #100, which includes runoff from the EX SE basin. The
Icpr stormwater modeling program was used to calculated the allowable release rate. Following is a
summary of those calculations:
Basin Area
(acre)
Curve
Number
Time of
Concentration
(min)
10-year
Runoff
(cfs)
EX SE 0.29 82.7 12 0.76
All of the proposed parking lot improvements have been graded to direct runoff to one of two
pervious asphalt pavement areas, PP1 and PP2. The bio-retention area watershed encompasses
mainly the bio-retention area. A portion of the existing driveway connection onto Michigan Road will
continue to drain toward Michigan Road since no new asphalt paving or grading will occur in that
area. The outlet orifice from the bio-retention area was set at a level to achieve storage of the
required water quality volume, as discussed in a later section. The Icpr stormwater modeling
program was used to design the detention systems and calculate the release rate from the overall
detention system. Following is a summary of those calculations:

Erosion Control and Water Quality Compliance
An onsite erosion control plan is designed to minimize the movement of sediments and other
pollutants both during construction and immediately after the completion of construction. The intent
of the plan is to comply with current IDEM "Rule 5" requirements. See the Site Construction Plans for
Erosion Control Plan Details and specifications.
The post-construction water quality treatment for the majority of the site will be provided through a
treatment train of two best management practices (BMP). Runoff will first be directed through the
pervious asphalt pavement, and then will receive a second level of treatment within the bio-retention
area. The water quality volume for this portion of the site was calculated according to the City of
Carmel Post-Construction Stormwater Quality Management Technical Standards. The water quality
volume is 1,568 CF, and the outlet orifice from the bio-retention area was set at an elevation to
achieve that amount of storage prior to discharging.
A small portion of the site contains an existing section of concrete pavement at the back of the
existing building. The northern portion of this concrete pavement will drain into PP2 and be treated
through the pervious pavement and bio-retention system. The southern portion of this concrete
pavement currently drains overland to the south and eventually flows into an existing pond located
offsite to the south. No work is being done within this area; however, water quality treatment is
required to be provided. The proposed water quality treatment train in this area will consist of a level
spreader and vegetative filter strip. Runoff from the existing concrete pavement will flow via
overland flow to the level spreader. The level spreader consists of a section of 1-foot wide by 2-feet
deep stone which will help slow down runoff, allowing some sediment to settle out, and will also
provide a level elevation for runoff to uniformly flow onto the vegetative filter strip.
The vegetative filter strip will consist of a strip of vegetation approximately 110 feet wide by 10 feet
long and will be planted with tall fescue and annual ryegrass, which will help sediment settle out and
also help remove other pollutants from the runoff. The water quality flow rate was calculated using
the Icpr stormwater modeling software. Following is a summary of those calculations:

Map symbols consist of a combination of letters or of letters and numbers. The first capital letter is the initial
one of the soil name. The second letter is lowercase and separates map units whose names begin with the
same letter. The third letter is a capital letter and indicates the class of slope. Symbols without a slope letter
are for miscellaneous areas, Udorthents, or nearly level soils. Some symbols have a number at the end and
are eroded phases. A final number of 2 indicates that the soil is moderately eroded, and a number 3
indicates that the soil is severely eroded.
