Woolpert Proposed Restaurant & Retail (Meijer Outlot C) – Carmel, IN
January 2018
Project Summary
This project consists of the development of an 11,760 sf multi-tenant building located within the
Meijer side parking lot north of the intersection of Pennsylvania Street & Carmel Drive in
Carmel, IN. The site consists of 2.00-acre lot and is bordered to the north, east, and south by
Meijer parking lot and to the west by Pennsylvania Street.
Pre-Developed Conditions
The site is currently developed as a parking lot for the Meijer Store. The existing drainage
patterns can be found in the previously approved drainage plan and report for the Meijer Store
dated April 1993. There is also an Existing Basin Map (Exhibit 1) that shows the storm basin
effective area. The development area drains south through the Meijer storm sewer to a detention
pond to the south end of the development.
The existing soils onsite are Crosby Silt Loam (CrA) and Brookston Silty Clay Loam (Br). These
soils are generally somewhat poorly drained to poorly drained soils and are typical for
agricultural Indiana areas. All soils for the curve number calculations were assumed to be type
D soils. See Appendix A1.
According to the FEMA Flood Insurance Rate Map, Community Panel 18057C0207G, the site
lies within Unshaded Zone X, outside the 100-yr floodplain. The FEMA FRIM can be found in
Exhibit 4.
Post-Developed Conditions
The developed conditions for the proposed area will include an 11,760 sf multi-tenant building,
and a parking lot with associated parking and appropriate lighting, landscaping and green space
per City of Carmel standards. The two acre site will convert an existing parking lot into a
proposed strip mall center. The improvements will be shown as one drainage area. The
stormwater will be collected through catch basins and routed through an Aqua-Swirl. Stormwater
is then released into the existing storm system running through the site that outlets to the
detention pond.
This development will reduce the existing curve number of 93 to 92 with at least the same
amount of green spaces provided. There is a small net loss in impervious area. A comparison of
the existing and proposed curve numbers can be found below in Table 1.

Storm Sewer Design
The proposed storm sewers for the site were designed utilizing the Rational method with the
software StormCAD. Proposed storm sewer drainage map can be found in Exhibit 3 and the
calculations can be found in Appendix B1 of this report. The storm sewers were sized for a 10-
year storm event. Although all storm sewers on site are private, hydraulic grade lines were
designed to be maintained within the pipes during the 10-year storm event and the structures
during the 100-year event.
Water Quality
The City of Carmel requires the removal of 80% TSS from the storm water for water quality.
The water quality volume was calculated using the first flush, 1” rainfall over the proposed
improvement area. The following has been provided to address the water quality within the
stormwater management system.
In order to meet stormwater quality requirements for the proposed site, an Aqua-Swirl and
permeable pavers have been designed. The west part of the site will be treated by the permeable
pavers while the east side and the building will be treated by an Aqua-Swirl. A Water Quality
basin map can be found in Exhibit 6.
The Flow Through BMP Sizing calculations were utilized per Chapter 701.04 of the Stormwater
Technical Standards Manual. Using PondPack, the SCS Type II 24 hour 1” storm was run and a
flow of 2.31 cfs was calculated to be the Water Quality treatment volume. An Aqua-Swirl was
sized for this flow rate and an AS-6 was chosen to treat this flow. The AS-6 has been sized to
meet these standards and provide water quality for an equivalent area to the area being disturbed.
An AS-6 can treat up to 2.32 cfs per City of Indianapolis Standards.
Water Quality calculations are provided in Appendix B3 of the report.
Conclusion
The proposed development will conform to the technical standards required by the City of
Carmel and to the existing conditions curve number. The drainage is being sufficiently addressed
for both runoff and water quality. Runoff from the site is being adequately detained through the
existing detention pond and stormwater quality is being improved by the proposed development.
Therefore, no adverse impacts are anticipated with this development.

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil

Please rely on the bar scale on each map sheet for map
measurements.

Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
