Stormwater Management Technical Report
KinderCare Learning Center – 10940 North Michigan Road, Carmel, IN 46032
Design by Crandall Engineering 2020-03-13
1. Project Description Narrative:
The project is a proposed commercial development (1.33 acres) and future
development sub-parcel (1.13 acres) on approximately 2.48 acres. The construction
will consist of commercial building (child daycare), asphalt parking, utility
extensions, and stormwater management.
2. Existing Condition:
a. The existing project site is an undeveloped open field with fallow ground cover.
Existing stormwater drains west to the pipe end section provided by the Michigan
Road Retail Project. No existing utility or building is located within the property
boundary.
3. Post-development Design (see post-development drainage map):
a. The proposed site includes the construction of the commercial building, parking,
utilities for the business, and stormwater system designed in accordance with “The
City of Carmel Stormwater Technical Standards Manual.”
b. The proposed stormwater pipe network is designed to handle the stormwater
discharge of a 10-year storm event. Stormwater will collect in catch basins and
discharge to an existing catch basin by connecting to the stormwater stub provided
for the site. The stations used in the stormwater calculations are as follows:
c. Station #1 consists of the northwest portion of the parking lot. It flows to the catch
basin CB102 at the northwest region of the lot. Then it discharges through the
underground pipe network to the existing stub connection.
d. Station #2 consists of the northeast portion of the lot. It flows to the catch basin
CB101 at the northeast region of the lot. Then it discharges through the underground
pipe network to the existing stub connection.
e. Station #3 consists of the northern half of the west parking lot and the play area. It
flows to the northwest corner of the parking, and to catch basin CB103 near the
depressed curb at that corner. Then it discharges through the underground pipe
network to the existing stub connection.
f. Station #4 consists of the north region of the roof. The west side of this station
discharges through roof drains and daylights at the curb face to the west parking lot.
Then it flows to catch basin CB103 and into the pipe network. The remainder of the
station discharges through roof drains to the north parking lot where it flows to catch
basin CB 101 and into the pipe network. Then it discharges through the underground
pipe network to the existing stub connection.
g. Station # 5 consists of the south region of the roof. The west side of this station
discharges through roof drains and daylights at the curb face to the west parking lot.
Then it flows to catch basin CB103 and into the pipe network. The remainder of the
station discharges through roof drains and daylights at the ditch to the south of the
building. It flows through the ditch to the end section with animal guard at the
southwest corner of the parcel. Then it discharges through the underground pipe
network to the existing stub connection.
h. Station # 6 consists of the grassy area to the east, west, and south of the lot.
Stormwater from the northwest region of the station flows to catch basin CB104 then
to the underground pipe network. The rest of the stormwater of this station flows
through the ditch to the south and to the end section with animal guard at the
southwest corner of the parcel. Then it discharges through the underground pipe
network to the existing stub connection.
i. Station #7 consists of the southern portion of the west parking and play area. It flows
west to the southwest corner of the parking, and to CB105 near the depressed curb at
that corner, then through the underground pipe network to the existing stub
connection.
4. Water Quality
a. Water quality for the proposed KinderCare Learning site will be treated off-site at the
Aria Development. Water quality will be provided with three mechanical water
quality units sized to serve the Aria development and the Michigan Road Retail Site
which includes the KinderCare Learning site. Refer to the “Stormwater Technical
Report for Michigan Road Site” which was approved for the Aria Development and
Michigan Road Retail Development for more details on the water quality units.
5. Stormwater Detention:
a. Stormwater detention and restricted release will be provided by a large detention
basin on the Aria Development site. This detention will store water for the multi-
family development and the Michigan Road Retail Site Development which includes
the proposed KinderCare Learning Center site. The runoff curve number for the
proposed KinderCare Learning Center site is 88.60. The detention sizing calculations
assumed a runoff curve number of 92.5 for this commercial development. Please
refer to the “Stormwater Technical Report for Michigan Road Site” which was
approved for the Aria Development and Michigan Road Retail Development for
more details on the detention sizing and release rate.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/
portal/nrcs/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

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
development of resource plans. If intensive use of small areas is planned, however,
Custom Soil Resource Report

onsite investigation is needed to define and locate the soils and miscellaneous
areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
