The sequencing is specified on this sheet.(See seasonal soil protection chart on this sheet).
B13. Material Handling and Spill Prevention Plan:
In order to minimize the release of potential pollutants during construction the Contractor
shall implement this material handling and spill prevention plan. The Contractor shall
review this plan with all subcontractors and require that they implement the plan as well.
1. Construction Equipment
a. Fueling, lubrication and fluids: All operations involving the addition of fluids
to equipment should be done in one location, as designated on Sheets C300, so
that spills are limited to one location on the site, which will facilitate the cleanup
of spills. If an onsite fueling tank is planned to be on site, it shall be double
walled and stored in this designated area. This location is an area that will not
allow spilled fluids to migrate into subsurface soils. In the event of a spill, the
fluid shall immediately be cleaned up by removing the contaminated soil or
stone which shall be disposed of in an acceptable manner. Spills on hard
surfaces shall be soaked up by an acceptable material such as Oil Dry and the
absorbent material disposed of in a proper manner. The spill shall also be
reported immediately to the Contractor's superintendent.
b. Equipment repair, especially when fluids must be removed from the
equipment or the possibility of fluid spills is high, should always be done offsite
at a facility that is more suitable than a construction site to handle spills. When
equipment must be repaired onsite it should be moved to the maintenance and
fueling area if possible. Otherwise, suitable on site containers should be placed
under the equipment during repair to catch any spilled fluids and these fluids
should be disposed of in a proper manner.
c. All reusable fluid containers, such as gasoline cans, shall be inspected for
leaks each time they are used. If leaks are found, the fluid shall be removed
from the container in a proper manner and the container disposed of in an
acceptable manner. Empty disposable containers, such as grease tubes and
lubricating oil and brake fluid containers, and their packaging, shall be disposed
of in a proper manner and shall not be left on the ground or in the open on the
construction site.

2. Construction Materials and Practices
a. Erosion control measures shown on these plans shall be implemented prior to
and during construction in the proper sequencing to minimize soil erosion.
Erosion controls shall be inspected and maintained as described elsewhere in
these plans. Excessive dusting of soil on the site shall be minimized by
reducing construction traffic across bare soil during dry and/or windy weather,
and by applying water or other acceptable dust control measures to the soil.
Upon completion of construction and suitable establishment of permanent
vegetation, temporary erosion control measures such as silt fence, check dams
and inlet protection devices shall be removed in a manner to minimize
additional land disturbance. Any areas disturbed by these operations shall be
properly revegetated.
b. Large waste materials created by cutting, sawing, drilling, or other operations
shall be properly disposed of in suitable onsite waste containers. The site shall o
be checked at the end of the day, as a minimum, and all waste materials,
including those blown across or off the site by wind, shall be picked up and
disposed of in suitable containers. Where possible, operations such as sawing
that create small particles should be performed in one spot in an area protected
from wind, and waste particles collected and disposed of frequently to minimize
wind dispersal.
Packaging used to transport materials to the site for construction of the facility
shall be disposed of properly, whether the material is taken out of its package
and incorporated into the project immediately or stored onsite for future use.
Packaged materials stored onsite shall be inspected regularly and any loose
packaging shall be repaired or disposed of properly.
c. All dewatering of activities shall be done in accordance to good erosion control
practices. These practices should include the use of dirt bags such as Dandy Dirt
Bags. The use of these types of dewatering devices will remove large quantities
of silt, sediment and dirt and prevent these materials to enter the storm sewer
system.
d. If the use of lime is used to stabilize the soil of the site then all construction
equipment used shall be cleaned of all excess material with water in the
maintenance and refueling area as shown within these plans.
e. Nutrients and fertilizers shall only be used to establish rapid vegetation. When
these products are utilized, the user should pay strict attention to the products
recommended usage.
3. Concrete Waste Water
a. All concrete waster water shall be disposed of in the designated area as shown on
Sheets C300 -C301. This area is a 4' high, 10' diameter doughnut type mulch berm which
shall be constructed over a geotextile fabric. This area shall be inspected on a daily basis
as a minimum. When this area becomes full, the pollutants shall be excavated, placed in
an acceptable container and disposed of in a proper manner.
4. Paint Products
a. All excess paint and there related products shall be disposed of in the manner at
which the manufacturer suggest. Under NO circumstances will paint or their related
products be cleaned or disposed of in soil, sanitary sewers, storm sewers, detention basins
or burned. Any violation of this shall be reported to the job superintendent.
5. Spill Response Directions
In the event of small spills please contact the construction supervisor.
In the event of spills that require removal of soils or other materials, please contact
the construction supervisor, developer, County Surveyor's Office and the Local Fire
Department.
In the event of spills that have potential groundwater or surface water
contamination, please contact the construction supervisor, developer, County Surveyor's
Office, Local Fire Department and IDEM.
See 0 M Manual for all Emergency Numbers.
B14. Monitoring and Maintenance Guidelines for Each Proposed Pollution
Prevention Mea sure: Person in charge of and knowledgeable about erosion and sediment
control shall inspect the site for stormwater pollution prevention deficiencies at least
daily and again within 24 hours of every 1/2 inch rain event.
See Erosion Crontrol Notes on this sheet for specifications.

Lots: Construction sequence for individual building lots is shown on this sheet.
Stormwater Pollution Prevention Plan
Post Construction Component
Cl. Description of Pollutants and Their Sources Associated with the Proposed
Land Use: Proposed site will be a multifamily subdivision. Potential pollutants
from this type of development include, but are not limited to: fluids and debris from
parked vehicles vehicular traffic which could include: fossil fuels, oil, grease,
antifreeze, brake fluid, window washer fluid, rubber, plastic, metal fragments, grit
(sediment) from wearing of the road surface, trash (including bacteria and other
biological agents contained in the trash) from littering and other types of improper
disposal or storage, and elevated receiving water temperatures from stormwater nmoff
contact with impervious surfaces.
C2. &C3. Sequence Describing Stormwater Quality Measure Implementation:
Description of Proposed Post Construction Stormwater Quality Measures:
The post construction measures used to minimize sedimentation in waterways include
swales and detention ponds. The swales will collect nmoff from the buildings and a
majority of the pavement. The design of the swales will allow sediment to be partially
infiltrated before storm water enters the designed storm sewer system. Beehive inlets will
prevent large items from entering the storm pipes and leaving the site. The detentions
basins, which is designed to have water in it at all times, will also help reduce sediment
and trash by allowing it to drop out prior to leaving the site. The owner also desires to
keep some of the wooded part of the site undisturbed during and after construction,
allowing existing vegetation to help remove sediment during and after construction.
C4. Location, Dimensions, Specifications and Construction Details of Each
Stormwater Quality Measures:
Catch basins, swales, and lake locations are provided on the site development plans.
Details are provided on the Construction Plan Detail sheets.
C5. Description of Maintenance Guidelines for Proposed Post Construction
Water Quality Measures:
Maintenance of all Stormwater pollution prevention measures will be the responsibility of
the project owner, Roehling Enterprises until a point in time in which the Home Owners
Association is established, utilizing procedures outline in the O &M manual for Post
Construction water quality measures. At that point said association shall assume all
maintenance responsibilities. The maintenance guidelines consist mostly of good
housekeeping measures. Any grassed or vegetated areas that experience erosion from
rainfall events should be repaired and revegetated as soon as possible. Trash or litter
should be picked up and properly disposed to prevent it from getting into the storm
drainage system and downstream waterways.
Erosion of the detention pond banks should be addressed as soon as it becomes visible by
filling the eroded area with suitable soil and establishing vegetation immediately,
preferably by sodding, or by seeding and mulching and monitoring until suitable
vegetation is established. The same measure should be used for steep banks of any earth
berm or any other steep area. The detention pond should also be monitored for sediment
coming from the storm drainage system. If the bottom of the pond receives sediment,
indicated by the sediment markers, it should be cleaned out and the source found and
repaired. The elevation of the pond bottom should be checked every 8 to 10 years and, if
significant sediment is encountered, it should be removed from the basin. This should be
done during periods of low rainfall to allow soil stirred up by excavation to settle out
before a rain event. The detention pond outlet should also be protected by adequate
filtration (rip -rap, shown on these plans) to prevent soil from entering the offsite storm
drainage system.
Pavement areas should also be monitored for pollutants. Any large quantity of fluids such
as oil, antifreeze, brake fluid, etc. found on the pavement should be reported to the Home
Owner Association and the source determined, if possible, and removed from the site for
maintenance or repair. Pavements should also be monitored for sediment coming from
vegetated areas that drain onto the pavement. If sediment is found it should be cleaned off
the pavement, and the source of the soil found and repaired as discussed above.

Brookston silty clay loom- this soil is dark colored, silty in texture and on depressional uplands. It is deep and very poorly
drained with moderate permeability. It has high available water for plant growth and high organic matter content. It has
compact till starting at a depth of 40 to 60 inches. The main soil features that affect the urban development uses are seasonal
high water table, high potential frost action, moderate shrink -swell potential, moderate permeability and ponded surface water.
Because of these engineering limitations this site will be constructed as follows. Weston Pointe, being a multifamily
development within the jurisdiction of The City of Carmel and Hamilton County will have to abide by the current
Subdivision Control Ordinance. This ordinance requires that we have an artificially drained site and that the buildings
within this development be wet above the 100yr elevation of the proposed detention basins and therefore be protected
from flooding. All buildings will be of large slab type construction. In cases where a high water table is present special footings
6' MIN, shall be constructed. All roads wit have adequate sub -base. At sanitary sewers shall be public and therefore no septic
systems shall be allowed
CrA Crosby silt loam, 0 -3 percent slopes- this soil is light colored, silty in texture and on sloping uplands. It is deep and somewhat
poorly drained with slow permeability. It has high available water for plant growth and medium organic matter content. The soil
has compact till starting at a depth between 20 -40 inches. The main soil features that affect urban development uses are
seasonal high water table, moderate shrink -swell potential, high potential frost action and slow permeability.
Because of these engineering limitations this site will be constructed as follows. Weston Pointe, being a multifamily
development within the jurisdiction of The City of Carmel and Hamilton County will have to abide by the current
Subdivision Control Ordinance. This ordinance requires that we have an artificially drained site and that the buildings
within this development be well above the 100yr elevation of the proposed detention basins and therefore be protected
from flooding. All buildings will be of large slab type construction. In cases where a high water table is present special footings
shall be constructed. All roads will have adequate sub -base. All sanitary sewers shall be public and therefore no septic

The sequencing is specified on this sheet.(See seasonal soil protection chart on this sheet).
B13. Material Handling and Spill Prevention Plan:
In order to minimize the release of potential pollutants during construction the Contractor
shall implement this material handling and spill prevention plan. The Contractor shall
review this plan with all subcontractors and require that they implement the plan as well.
1. Construction Equipment
a. Fueling, lubrication and fluids: All operations involving the addition of fluids
to equipment should be done in one location, as designated on Sheets C300, so
that spills are limited to one location on the site, which will facilitate the cleanup
of spills. If an onsite fueling tank is planned to be on site, it shall be double
walled and stored in this designated area. This location is an area that will not
allow spilled fluids to migrate into subsurface soils. In the event of a spill, the
fluid shall immediately be cleaned up by removing the contaminated soil or
stone which shall be disposed of in an acceptable manner. Spills on hard
surfaces shall be soaked up by an acceptable material such as Oil Dry and the
absorbent material disposed of in a proper manner. The spill shall also be
reported immediately to the Contractor's superintendent.
b. Equipment repair, especially when fluids must be removed from the
equipment or the possibility of fluid spills is high, should always be done offsite
at a facility that is more suitable than a construction site to handle spills. When
equipment must be repaired onsite it should be moved to the maintenance and
fueling area if possible. Otherwise, suitable on site containers should be placed
under the equipment during repair to catch any spilled fluids and these fluids
should be disposed of in a proper manner.
c. All reusable fluid containers, such as gasoline cans, shall be inspected for
leaks each time they are used. If leaks are found, the fluid shall be removed
from the container in a proper manner and the container disposed of in an
acceptable manner. Empty disposable containers, such as grease tubes and
lubricating oil and brake fluid containers, and their packaging, shall be disposed
of in a proper manner and shall not be left on the ground or in the open on the
construction site.

2. Construction Materials and Practices
a. Erosion control measures shown on these plans shall be implemented prior to
and during construction in the proper sequencing to minimize soil erosion.
Erosion controls shall be inspected and maintained as described elsewhere in
these plans. Excessive dusting of soil on the site shall be minimized by
reducing construction traffic across bare soil during dry and/or windy weather,
and by applying water or other acceptable dust control measures to the soil.
Upon completion of construction and suitable establishment of permanent
vegetation, temporary erosion control measures such as silt fence, check dams
and inlet protection devices shall be removed in a manner to minimize
additional land disturbance. Any areas disturbed by these operations shall be
properly revegetated.
b. Large waste materials created by cutting, sawing, drilling, or other operations
shall be properly disposed of in suitable onsite waste containers. The site shall o
be checked at the end of the day, as a minimum, and all waste materials,
including those blown across or off the site by wind, shall be picked up and
disposed of in suitable containers. Where possible, operations such as sawing
that create small particles should be performed in one spot in an area protected
from wind, and waste particles collected and disposed of frequently to minimize
wind dispersal.
Packaging used to transport materials to the site for construction of the facility
shall be disposed of properly, whether the material is taken out of its package
and incorporated into the project immediately or stored onsite for future use.
Packaged materials stored onsite shall be inspected regularly and any loose
packaging shall be repaired or disposed of properly.
c. All dewatering of activities shall be done in accordance to good erosion control
practices. These practices should include the use of dirt bags such as Dandy Dirt
Bags. The use of these types of dewatering devices will remove large quantities
of silt, sediment and dirt and prevent these materials to enter the storm sewer
system.
d. If the use of lime is used to stabilize the soil of the site then all construction
equipment used shall be cleaned of all excess material with water in the
maintenance and refueling area as shown within these plans.
e. Nutrients and fertilizers shall only be used to establish rapid vegetation. When
these products are utilized, the user should pay strict attention to the products
recommended usage.
3. Concrete Waste Water
a. All concrete waster water shall be disposed of in the designated area as shown on
Sheets C300 -C301. This area is a 4' high, 10' diameter doughnut type mulch berm which
shall be constructed over a geotextile fabric. This area shall be inspected on a daily basis
as a minimum. When this area becomes full, the pollutants shall be excavated, placed in
an acceptable container and disposed of in a proper manner.
4. Paint Products
a. All excess paint and there related products shall be disposed of in the manner at
which the manufacturer suggest. Under NO circumstances will paint or their related
products be cleaned or disposed of in soil, sanitary sewers, storm sewers, detention basins
or burned. Any violation of this shall be reported to the job superintendent.
5. Spill Response Directions
In the event of small spills please contact the construction supervisor.
In the event of spills that require removal of soils or other materials, please contact
the construction supervisor, developer, County Surveyor's Office and the Local Fire
Department.
In the event of spills that have potential groundwater or surface water
contamination, please contact the construction supervisor, developer, County Surveyor's
Office, Local Fire Department and IDEM.
See 0 M Manual for all Emergency Numbers.
B14. Monitoring and Maintenance Guidelines for Each Proposed Pollution
Prevention Mea sure: Person in charge of and knowledgeable about erosion and sediment
control shall inspect the site for stormwater pollution prevention deficiencies at least
daily and again within 24 hours of every 1/2 inch rain event.
See Erosion Crontrol Notes on this sheet for specifications.

Cl. Description of Pollutants and Their Sources Associated with the Proposed
Land Use: Proposed site will be a multifamily subdivision. Potential pollutants
from this type of development include, but are not limited to: fluids and debris from
parked vehicles vehicular traffic which could include: fossil fuels, oil, grease,
antifreeze, brake fluid, window washer fluid, rubber, plastic, metal fragments, grit
(sediment) from wearing of the road surface, trash (including bacteria and other
biological agents contained in the trash) from littering and other types of improper
disposal or storage, and elevated receiving water temperatures from stormwater nmoff
contact with impervious surfaces.
C2. &C3. Sequence Describing Stormwater Quality Measure Implementation:
Description of Proposed Post Construction Stormwater Quality Measures:
The post construction measures used to minimize sedimentation in waterways include
swales and detention ponds. The swales will collect nmoff from the buildings and a
majority of the pavement. The design of the swales will allow sediment to be partially
infiltrated before storm water enters the designed storm sewer system. Beehive inlets will
prevent large items from entering the storm pipes and leaving the site. The detentions
basins, which is designed to have water in it at all times, will also help reduce sediment
and trash by allowing it to drop out prior to leaving the site. The owner also desires to
keep some of the wooded part of the site undisturbed during and after construction,
allowing existing vegetation to help remove sediment during and after construction.
C4. Location, Dimensions, Specifications and Construction Details of Each
Stormwater Quality Measures:
Catch basins, swales, and lake locations are provided on the site development plans.

Water Quality Measures:
Maintenance of all Stormwater pollution prevention measures will be the responsibility of
the project owner, Roehling Enterprises until a point in time in which the Home Owners
Association is established, utilizing procedures outline in the O &M manual for Post
Construction water quality measures. At that point said association shall assume all
maintenance responsibilities. The maintenance guidelines consist mostly of good
housekeeping measures. Any grassed or vegetated areas that experience erosion from
rainfall events should be repaired and revegetated as soon as possible. Trash or litter
should be picked up and properly disposed to prevent it from getting into the storm
drainage system and downstream waterways.
Erosion of the detention pond banks should be addressed as soon as it becomes visible by
filling the eroded area with suitable soil and establishing vegetation immediately,
preferably by sodding, or by seeding and mulching and monitoring until suitable
vegetation is established. The same measure should be used for steep banks of any earth
berm or any other steep area. The detention pond should also be monitored for sediment
coming from the storm drainage system. If the bottom of the pond receives sediment,
indicated by the sediment markers, it should be cleaned out and the source found and
repaired. The elevation of the pond bottom should be checked every 8 to 10 years and, if
significant sediment is encountered, it should be removed from the basin. This should be
done during periods of low rainfall to allow soil stirred up by excavation to settle out
before a rain event. The detention pond outlet should also be protected by adequate
filtration (rip -rap, shown on these plans) to prevent soil from entering the offsite storm
drainage system.
Pavement areas should also be monitored for pollutants. Any large quantity of fluids such
as oil, antifreeze, brake fluid, etc. found on the pavement should be reported to the Home
Owner Association and the source determined, if possible, and removed from the site for
maintenance or repair. Pavements should also be monitored for sediment coming from
vegetated areas that drain onto the pavement. If sediment is found it should be cleaned off
the pavement, and the source of the soil found and repaired as discussed above.

CONSTRUCTION ENTRANCE DETAIL
Brookston silty clay loom- this soil is dark colored, silty in texture and on depressional uplands. It is deep and very poorly
drained with moderate permeability. It has high available water for plant growth and high organic matter content. It has
compact till starting at a depth of 40 to 60 inches. The main soil features that affect the urban development uses are seasonal
high water table, high potential frost action, moderate shrink -swell potential, moderate permeability and ponded surface water.
Because of these engineering limitations this site will be constructed as follows. Weston Pointe, being a multifamily
development within the jurisdiction of The City of Carmel and Hamilton County will have to abide by the current
Subdivision Control Ordinance. This ordinance requires that we have an artificially drained site and that the buildings
within this development be wet above the 100yr elevation of the proposed detention basins and therefore be protected
from flooding. All buildings will be of large slab type construction. In cases where a high water table is present special footings
6' MIN, shall be constructed. All roads wit have adequate sub -base. At sanitary sewers shall be public and therefore no septic
systems shall be allowed
CrA Crosby silt loam, 0 -3 percent slopes- this soil is light colored, silty in texture and on sloping uplands. It is deep and somewhat
poorly drained with slow permeability. It has high available water for plant growth and medium organic matter content. The soil
has compact till starting at a depth between 20 -40 inches. The main soil features that affect urban development uses are
seasonal high water table, moderate shrink -swell potential, high potential frost action and slow permeability.
Because of these engineering limitations this site will be constructed as follows. Weston Pointe, being a multifamily
development within the jurisdiction of The City of Carmel and Hamilton County will have to abide by the current
Subdivision Control Ordinance. This ordinance requires that we have an artificially drained site and that the buildings
within this development be well above the 100yr elevation of the proposed detention basins and therefore be protected
from flooding. All buildings will be of large slab type construction. In cases where a high water table is present special footings
shall be constructed. All roads will have adequate sub -base. All sanitary sewers shall be public and therefore no septic
systems shall be allowed
MmB2 Miami silt loam, 2 -6 percent slopes- this soil is light colored, silty in texture and on sloping uplands. It is deep and well drained
with moderate permeability. It has moderate available water for plant growth and a medium organic matter content. It has
compact till starting at a depth between 20 -40 inches. The main soil features that adversely affect urban development uses are
moderate potential frost action, moderate shrink -swell potential, moderately slow permeability, low strength and erosion during
construction.
Because of these engineering limitations this site will be constructed as follows. The foundations and footings used
in this development shall be designed to include foundation drain tiles as to help prevent structural damage from
shrinking and swelling and low strength. There will be no septic fields in this development. All roads will have adequate sub -base.
1.
Fill geotextile bags approximately half full
with 2 to 3 inch stone or mulch.
2. At a position downslope of the lot and upslope
of the inlet, lay bags tightly in a row curving
upslope from curb and away from inlet.
3. Overlap bags onto the curb and extend a min-
imum of 3 feet into the street.
4. For additional layers, overlap bags with the
row beneath, and leave a one -bag gap in the
middle of the top row to serve as a spillway.
5. Place bags in an arc around curb inlets that
are in a sump position.
6. Set up safety /traffic barriers to keep vehicles
from hitting bags, causing possible injury.
7. Inspect and repair as needed, and remove any
accumulated sediments after every storm.
