Jackson's Grant I CARMEL, INDIANA
Preface
This Operations and Maintenance Manual (O&M) has been prepared based on guidelines published in the CITY OF
CARMEL STORMWATER TECHNICAL STANDARDS MANUAL for Republic Development, LLC (OWNER).
Stormwater Management Guidelines
Jackson’s Grant is a 266 acre +/- development located in the Williams creek watershed. The main purpose of the
stormwater management BMPs is for water quantity and quality control by reducing peak runoff and pollutant loading
that would discharge to Williams Creek from the increased impervious nature of residential development.
Per the City of Carmel Stormwater Technical Standards Manual, runoff from development must be routed through
two separate BMPs prior to discharge. This project utilizes numerous small, distributed stormwater BMPs to achieve
the required TSS removal. These BMPs include native dry detention basins with combinations of low flow swales,
infiltration trenches, and constructed wetlands. In general, stormwater runoff is directed into depressed areas with
wet tolerant native plantings, allowed to percolate, and then discharged. The invert of all BMPs has been depressed
to promote infiltration, temperature control, pollutant load reduction, and suspended solids settlement.
Purpose
This Operation and Maintenance manual defines requirements for operating, inspecting and maintaining Jackson’s
Grant including all Best Management Practices (BMPs) constructed as part of the sustainable sites engineering plans
prepared by Williams Creek Consulting (ENGINEER) on behalf of the OWNER. The proposed BMPs intend to provide
natural and sustainable water quality improvement.
The OWNER will be responsible for all maintenance and costs associated with routine inspections and maintenance of
the integrated stormwater management system BMPs.
Brief descriptions of what each BMP is intended to accomplish and the physical processes which govern its behavior
are included within the following manual. Inspection and maintenance guidelines specified in this manual should be
implemented in order to ensure that BMPs achieve their full performance capabilities.

Introduction
This document defines responsibilities for operating, inspecting and maintaining the Native Dry Detention
Basin Best Management Practices (BMPs) within Jackson’s Grant within Carmel, Indiana. An annual report
will need to be submitted to the City of Carmel Engineering Department, Attn: Storm Water Administrator,
One Civic Square, Carmel, IN 46032.
Native Dry Detention BMP
City of Carmel as well as Hamilton County personnel will have the right to enter the premises to perform
compliance inspections of all permanent BMPs. However, routine monthly and annual inspection of the
native/infiltration basin BMP is the responsibility of the owner. Additional inspections (using the monthly
checklist) are required within 48 hours of the end of any significant rainfall event (2 inches or more within
24 hours). Sample monthly inspection logs are included within this manual.
Monthly Inspections
The following areas should be inspected on a monthly basis:
Vegetation
• Some species of plants are considered invasive and should be eradicated within one month of
discovery. Invasive species include reed canary grass (Phalaris arundinacea), purple
loosestrife (Lythrum salicaria), common reed (Phragmites australis), and narrowleaf cattail
(Typha angustifolia.). The Appendix contains photos of these four common invasive species.
• If invasive volunteer trees appear, they should be documented for removal.
• Landscaped area of the banks that are eroded or have exposed bare earth shall be restored to
proper grade, stabilized and re-seeded with the appropriate native seed mixtures.
Floating Pollutants
• Remove all floatable debris.
• Note visible pollution such as oily sheens, discoloration, and cloudy or muddy water
• Remove shoreline pollution such as trash or oily liquids
• Miscellaneous debris
Erosion
• Inspect inlet, outlet, headwall and endwall areas for erosion and undercutting. If erosion is
occurring, then additional scour protection measures will need to be employed.
• Areas of severe erosion or other conditions that may constitute a public hazard should be
corrected as soon as possible and prior to the next monthly inspection.
Outlet
• All pond outlets shall be inspected and checked for debris and obstructions that disrupt the
flow within the storm water management system. If any pipes are obstructed, they must be
cleared.
Embankments
• Animal burrows – Burrowing mammals should be controlled or eradicated when present in
densities that endanger the integrity of the embankment. Damage caused by their burrowing
must be repaired as soon as possible. Any burrowing mammal control effort will need to be
carefully planned and executed to avoid negative impacts on adjacent habitats and wildlife.
Such measures will be confined to the embankment. Mammals that may be of concern are
beavers (Castor canadensis), and muskrat (Ondatra zibethica).
POST CONSTRUCTION OPERATION AND MAINTENANCE MANUAL I WILLIAMS CREEK CONSULTING, INC. I 19
Jackson's Grant I CARMEL, INDIANA• Slope protection failure – Inspect the slopes of the BMP for any sliding or scour protection
displacement. Please note location and describe the failure.
Maintenance
Maintenance responsibilities shall remain in effect for the life of the BMP from the date the construction is
completed. Data sheets are included to evaluate each area of concern.
Vegetation
Although the BMP is expected to develop into a system that will eventually require little or no vegetation
maintenance, some vegetation maintenance will be required in the first 2 years following
construction in order to give the new vegetation communities a chance to become well established.
Precautionary measures must be taken to prevent invasive species from establishing. These species
should be either physically removed or treated with herbicide by qualified plant maintenance professional.
Physical removal is strongly preferred above the application of herbicide. If herbicide is used, it must be
applied by State Chemists Office approved applicators and any application must be approved by the City of
Carmel Utility Department prior to application. Replant or reseed vegetation when damaged, vandalized or
removed in compliance to original planting specifications.
Mowing Plan
If turf grass surrounds BMP, once established, turf grass height shall be maintained at a minimum height
of four (4) inches to control weeds. Not more than ½ of the grass leaf shall be removed by the initial cutting
or subsequent cutting. Do not mow any live native herbaceous plant area.
Fertilizer
No fertilizer is to be used unless soil testing has found specific deficiencies in nutrients.
Herbicide and Pesticide Guidance
Throughout the first year, treat any weeds, non-native or invasive species with glyphosate herbicide
approved for use around water (Rodeo) by spot-spraying or other means that minimize incidental herbicide
drift. Herbicide application should be conducted on, windless days so that the chemical does not spread or
volatize. Re-seed and/or replant any die-back resulting from incidental treatment with herbicide.
Pre-emergent herbicides to be used on upland areas adjacent to stormwater management BMPs and other
native landscape areas without native seed, or at least one year following seed installation, consist of
prodiamine herbicides such as Barricade. Pre-emergent herbicides shall not be applied to plantings
located in standing water.
All herbicides must be applied by State Chemists Office approved applicators and any application must be
approved by the City of Carmel Utility Department prior to application.
Spill Response Plan
The proposed land use will consist of single family residential houses. The pollutants and sources of each
pollutant normally expected from these types of land uses are listed below:
• Pollutant Source: Passenger vehicles, delivery vehicles, and trucks
o Type of Pollutant: Oil, gasoline, diesel fuel, any hydrocarbon associated with vehicular
fuels and lubricants, grease, antifreeze, windshield cleaner solution, brake fluid, brake
dust, rubber, glass, metal and plastic fragments, grit, road de-icing materials

SUMP CATCH BASINS
THE HAMLET AT JACKSON’S GRANT, SECTION 2
PURPOSE & BACKGROUND
The BMP’s for The Hamlet at Jackson’s Grant, Section 2, are sump catch basins located at specified
structures prior to or at the outlets of the BMP Basins (see construction documents or BMP
Location Map). The sump catch basins are storm structures constructed with a sump which serves
as a sediment storage basin that can be accessed and cleaned out when necessary.
INSPECTION & MAINTENANCE ACTIVITIES
The performance of a sump catch basin is highly dependant on the inspection and maintenance of
the structure. If the structure is not properly maintained, the ability to remove pollutants will
decrease. The BMP owner will need to provide the maintenance for the sediment removal.
The BMP owner agrees to the following monthly inspection program:
1. Remove manhole lid or open pavement grate to expose inside of box structure.
2. Lower a dip stick equipped with a ball valve (Sludge Judge or similar device) into opened
box structure.
3. Measure the depth of sedimentation. The level of sedimentation shall not exceed 12
inches before maintenance.
4. In the event that maintenance is required, call a local vactor company to remove
sediments and other debris with a vacuum truck. Dispose of all waste in accordance
with the City of Westfield and any applicable state, and/or federal requirements.
Along with these monthly inspection reports, the BMP owner agrees to the submittal of annual
inspection reports to the City of Carmel Engineering due one year after construction is completed,
with subsequent reports due each year within the same month of the initial report.

OUTLET CONTROL STRUCTURES
THE HAMLET AT JACKSON’S GRANT, SECTION 2
PURPOSE & BACKGROUND
There are basin areas within the project that use Outlet Control Structures in order to restrict flows
and allow sediment and other debris to settle prior to moving into the downstream storm sewer
system. This is accomplished by smaller orifice openings on the basin side of the structures. Some
of these structures have larger openings on top of the structure for heavier rain events. One of these
structures is a BMP for The Hamlet at Jackson’s Grant, Section 2. This structure is labelled #638
and the details for this structure are provided in this manual (also see construction documents or
BMP Location Map).
INSPECTION & MAINTENANCE ACTIVITIES
The performance of these Outlet Control Structures are highly dependent on the inspection and
maintenance of the structure. Protection from clogging is required for any orifice size. Smaller
orifice openings are more susceptible to clogging, which prevents the structure control from
performing its function and potentially causing adverse impacts. If the structure is not properly
maintained, the ability to remove pollutants will decrease. The BMP owner will need to provide the
maintenance for the sediment removal.
The BMP owner agrees to the following monthly inspection program:
1. Outlet control structures should be inspected after several storms to ensure that they are
functioning properly and that there are no erosion or debris problems developing.
2. Inspect for sediment and/or debris buildup. Sediment or debris blocking any of the
orifice openings or the opening on the top of the structure restrict the effectiveness of
the structure.
3. In the event that maintenance is required, remove sediments and other debris. Dispose
of all waste in accordance with the City of Carmel and any applicable state, and/or
federal requirements.
