IEI. Proj. No. 0335
Site Location
The proposed project is located on a tract of at the southwest corner of Main
Street and Guilford Road. The parcel is part of the West Half of the Southwest
Quarter of Section 25, Township 18 North, Range 3 East in Hamilton County,
Carmel, Indiana. The
Proiect Description
The proposed Project is to redevelop the existing vacated gas and service station
by demolishing the existing facilities and parking and construction a new
approximate 7,542 s.f. building footprint. The proposed building will include a
seven bay automotive service and repair business, in addition a possible caf6,
office or retail tenants. The development of the site will include providing 38
parking spaces, associated drives, curbing, sidewalks, landscaping, site lighting
& a detention basin.
ME
Existin¢ Site Conditions
The total existing site is a 1.32-acre tract of land including the street right-of-
way. The site is 0.88-acre excluding the street right-of-way. The site is presently
a vacated gas and service station consisting of a building, canopy, parking and
circulation. The existing facilities will be completely demolished to develop the
site. The existing site generally drains to the south — southwest. A portion of the
site, approximately 1/3 drains into the ditch along the south side of Main Street.
The ditch along the south side of Main Street flows west approximately 200' into
an existing storm pipe that flows south along the western property line of the
west adjoining property of the proposed developed site. The south lii to 2/3's of
the site sheet drains to the south/south-west across the adjoining west property
into an existing inlet that is part of the storm pipe system that collects drainage
from the ditch along the south side of Main Street. See the included Drainage
Area Map for additional detail. There is approximately 6-7 feet of elevational
change from the eastern portion of the site to the west.
Proposed Storm Water Drainane System
The proposed storm water drainage system for the site will include a dry
detention basin located at the southwest corner of the site. The storm water
detention basin will collect all the developed site building and parking area that is
approximately 0.80 acres of the site after additional right-of-way is dedicated to
the City of Carmel. The remaining 0.52-acres of the site is the existing street
right-of-way and the additional 20 feet of future right-of-way along Main Street
that consist of right-of-way pavement, sidewalk and grass. The existing and
future street right-of-way will be collected into a storm pipe and inlet system and
discharged into the existing ditch along the south side of Main Street. The
detention basin will out let through a storm pipe that will be connected to the
existing storm pipe collection system along the western portion of the west
adjacent property. The detention basin is being developed with a retaining wall
along the southwest corner of the property to maximize the detention volume
available in the area at the site. There is approximately 0.0386-acres of lawn that
sheet drains directly off the western portion of the site. The allowable outflow
rate from the detention basin has been adjusted for the direct runoff area.
The dry detention basin will outlet off -site through a 12" storm pipe which will
be constructed in an easement obtained from James & Paula Quinn. The
connection is approximately 110 feet to the west. Thel2" pipe will be connected
to an existing 15" storm pipe which changes to an 18" pipe approximately 10'
down stream. As shown on the attached exhibit in the drainage summary and the
site survey, this storm system drains the proposed site, the adjacent western
office building and the south portion of the Main Street right-of-way from
Guilford to just west of a beehive as on the exhibit. As discussed previously, the
proposed site drains into the offsite storm system through the ditch along the
south side of Main Street and also across the southern portion of the Quinn
property. After an initial analysis of the system and the area, the 15" storm has a
-4-
capacity of over 10 cfs and the contributing flow to the system at the connection
point calculated to be 6.86 cfs for the 10-year event and 9.92 cfs for the 100-year
event. Therefore, since the proposed site will be providing detention for the
developed runoff to existing conditions, the proposed development will not
adversely affect the offsite system.
The following are runoff rates for the existing and developed conditions for the
project.
Existing:
Q an = 1.62 cfs
Q io-,+ = 2.46 cfs
Q imn = 3.58 cfs
Developed Runoff to Detention Basin:
Q z-,* = 2.24 cfs
Q 10-n = 3.29 cfs
Q 100-n= 4.65 cfs
Developed Runoff for Western Direct Discharge:
Q an = 0.05 cfs
Q myr = 0.10 cfs
Q,aan= 0.17 cfs
Allowable Developed Runoff from Detention Basin:
Q vn =
1.57
cfs
Q ian =
2.36
cfs
Q wun=
2.29
cfs
Developed Detention Basin Discharge:
Q 2-n =
1.52
cfs
Q Io-yr =
1.92
cfs
Q iaay'=
2.26
cfs
The proposed storm water detention basin will limit the discharge from the site in
the proposed developed condition to the existing 2-yr and 10-yr runoff rates as
summarized above and meets the requirements for detention design by the City
of Carmel.
See Attached Appendix "A", `B" and "C" for Project Site information and Design Calculations.
