CHAPTER I
GENERAL PROVISIONS
1.1 Title
This ordinance will be known and may be cited and referred to as the "Storm Drainage,
Erosion Control, and Sediment Control Ordinance of the City of Jeffersonville.
Indiana" and will hereafter be referred to as "this ordinance".
1.2 Purpose
It is the purpose of this ordinance to reduce the hazard to public health and safety
caused by excessive storm water runoff and erosion: to reduce the economic hardships
caused by excessive storm water runoff and erosion; and to protect, conserve, and
promote the orderly development of land and water resources within the regulated area.
1.3 Applicability
This ordinance applies to all development which requires official review and approval
of any of the following agencies of the City of Jeffersonville: Plan Commission or its
Plat Review Committee, Board of Zoning Appeals, Board of Public Works and Safety,
City Engineer, or Building Commissioner.
Projects that consist of a single family dwelling, a two-family dwelling, or their
accessory structures are not subject to these requirements.
Recognizing that land-disturbing activities may cause soil loss, siltation, and
degradation of natural resources, the erosion control standards of this ordinance are
. applicable to all land-disturbing activities that are necessary for any development
regulated by this ordinance.
1.4 Conflicting Ordinance
The provisions of this ordinance are additional requirements to minimum standards
required by other ordinances of the City, particularly Section 155.46, Storm Drainage,
of the Subdivision Control Regulations, Ordinance 96-OR-28, dated June 4, 1996, or
its latest revision. In the case of conflicting requirements, the most restrictive apply.
1.5 Policy
Streams and drainage channels serving the City of Jeffersonville may not have
sufficient capacity to receive and convey storm water runoff resulting when land use
changes from underdeveloped or agricultural use to a more urbanized use. In addition,
deposits or sediment from developments during and after construction can reduce
capacities of storm sewers and drainage facilities and result in damages to receimng
lakes and streams.
Therefore, the City of Jeffersonville Drainage Board must require that all new
development, redevelopment and other new construction in the City of Jeffersonville
store storm water runoff and provide for its controlled release, except as exempted in
Section 1.3. The storm water release rate of a one hundred (100) year storm event
from development, redevelopment, and new construction must not exceed the storm
water runoff from a ten (10) year storm event from the land area prior to the new
development, redevelopment, or new construction or the capacity of its drainage outlet,
whichever is more restrictive. There may be certain circumstances where detention is
not justified or may be detrimental to the overall drainage basinl The Drainage Board
may waive detention requirements in these cases.
1.6 Permits For Construction In A Floodway
1.7
The 1945 Flood Control Act (Indiana Code 13-2-22) of the State of Indiana prohibits
the construction of abodes or residences in or on a floodway. Prior approval of
Department of Natural Resources is required for any type of construction, excavation,
or filling in or on a floodway.
All applications made to, and granted approval by, the Department of Natural
Resources do not in any way relieve the owner of the necessity of securing easements
or other property rights, permits or approvals from affected property owners and local,
state, and federal agencies.
Wetlands
Landowners and/or developers must notify and make application to all appropriate state
and federal agencies with authority for wetland protection. In cases where federal or
state jurisdictional wetlands have been determined to exist, those wetland areas and
boundaries must be indicated on preliminary and final drainage plans.
The Board will not make determinations of the accuracy of delineation or extent of
jurisdictional wetlands. Approvals required by this ordinance may be deferred until
wetland-related approvals have been obtained.
1.8 Adequate Drainage Outlets
All projects subject to this ordinance must provide drainage outlets whose adequacy
is based upon the following standards:
ho
Use of the outlet will not increase the velocity or rate of outflow above that
allowed by this ordinance;
Bo
The outlet must be approved by all involved regulatory agencies including
the Board; and
C. Use of the outlet will not cause hardship or compound existing problems.
The following outlets will generally not be deemed to be adequate:
A. An outlet that is not legally and physically accessible and maintainable;
Overland flow that is not a watercourse as def'med by this ordinance;
C. Existing or future city roadside ditches, unless specifically approved;
D. Agricultural field tiles for surface water, and
Railroad side ditches without adequate improvements, unless specifically
approved.
1.9 Compliance with 327 IAC 15-5
All land-disturbing activities that disturb five (5) acres or more in total must comply
with 327 IAC 15-5 (Rule 5) "Storm Water Runoff Associated With Construction
Activity." It is the responsibility of the landowner or developer to determine if this
role applies to his/her project. The Board will make no determination of the
applicability of this role to individual projects. Copies of Notice of Intent (NOI) letters
must also be filed with the Jeffersonville City Engineer's Office prior to
commencement of the land-disturbing activity.
1.10 Compliance
In addition to the requirements of this ordinance, compliance with the requirements set
forth in other applicable City ordinances with respect to submission and approval of
primary and secondai'y subdivisions, site plan review, improvement plans, building and
zoning permits, construction inspections, appeals, and similar matters, and compliance
with applicable State of Indiana statutes and regulations, is required.

Ho
The erosion and sediment control measures to be implemented including,
but not limited to: design and installation details, location, vegetation
and schedule.
3.3 Submittal and Consideration of Plans
All applications must be submitted at least forty-five (45) days before the drainage
board meeting at which the application is to be considered on forms approved by the
Board and provided by the City Planner's Office. All applications must include a site
map. For projects which require approval through the Plan Commission and/or its Plat
Committee, such as subdivisions and site plan reviews, applicants must submit
preliminary and final plats to the Board pursuant to this ordinance, as well as to the
Plan Commission or its Plat Committee. The professional who prepared the plans
included with the application must attend any Board meeting at which the application is
considered.
¸3.4
The Board will give notice of its decision to the applicant. The Board must approve or
disapprove the plans within forty-five (45) days of submission unless the applicant
. consents to a continuance or extension. All approvals and disapprovals, with written
reasons therefor, must be incorporated into the Board minutes.
The Board may grant exemptions from any or all requirements of this ordinance and
waive any requirements of this ordinance at its discretion.
Determination of Runoff Quantifies
Runoff quantities must be computed for the watersheds within the parcel under
development. The quantity of runoff which is generated as the result of a given rainfall
intensity may be calculated as follows:
For areas up to and including two hundred (200) acres, the Rational Method
may be used: The peak rate of runoff (Q) in cubic feet per second is computed
as Q=CIA;
Where:
C = runoff coefficient, representing the characteristics of the drainage area and
defined as the ratio of runoff to rainfall;
I = average intensity of rainfall in inches per hour for a duration equal to the
time of concentration (tc) for a selected rainfall frequency; and
fn:8708/a~l~co.d0c[~m] 14
A = tributary drainage area :in acres.
Guidance for selection of the runoff coefficients is to be found in appropriate
design manuals. Rainfall intensity must be determined from the rainfall
frequency curves found in standard design manuals for this region or from data
shown. The time of concentration (tc) to be used must be the sum of the inlet
time and flow time in the drainage facility from the most remote part of the
drainage area to the point under consideration. The flow time in the storm
sewers may be estimated by the distance in feet divided by velocity of flow in
feet per second. The Manning Formula must be used to determine the velocity.
Other methods of determining runoff may be used upon approval of the Board.
Computer programs may be used and computer printouts submitted for drainage
calculations provided details of the program and the assumptions made by that
program are submitted with the calculations and approved by the Board. The
Board may require other methods of determining runoff.
3.5 .Amount of Runoff to be Accommodated by Various Parts of Drainage Facility
Various parts of a drainage facility must accommodate runoff water as follows:
The drainage facilities, including but not limited to, inlets, catch basins, street
gutters, component swales, storm sewers and small channels, which collect
storm water must accommodate peak runoff from at least a ten (10) year return
period storm. The allowable spread of water on collector streets is limited to
maintaining two (2) clear ten (10) foot moving lanes of traffic. One (1) lane is
to be maintained on local roads and subdivisions streets.
For rainfall heavier than a ten (10) year storm, these minimum requirements
must be satisfied:
(A)
(B)
(c)
Open channels carrying peak flows greater than thirty (30) cubic feet per
second must be capable of accommodating peak runoff for a fifty (50)
year return period storm within the drainage easement;
New dulverts must be capable of accommodating peak runoff from a
fifty (50) year return period storm when crossing under a road which is
part of the Indiana Department of Transportation functional classification
system and is classified as principal or minor arterial, or major or minor
collector road; and
Drainage facilities must have adequate capacity to convey the storm
water runoff from all upsfream tributary areas through the development
under consideration for a storm of one hundred (100) year design return
period calculated on the basis of the upstream land in its present state of
development. An allowance, equivalent to the reduction in flow rate
provided, must be made for upstream detention when such upstream
detention and release rate have previously been approved by the Board
and evidence of its construction can be shown.
3.6 Drainage Easements
Drainage easements must be provided to cover all elements of the drainage facility and
must be designed:
1. To be adequate to install and maintain the drainage facilities;
2. To minimize conflicts with utility easements;
3. To maintain a sufficient buildable area on each lot or parcel;
To be at least fifteen (15) feet wide.
No building, fence, trees or shrubs may be placed within the drainage easement.
CHAPTER 4
STORM SEWER DESIGN STANDARDS
All storm sewers, whether public or private and whether constructed on public or private
property, must conform to the design standards and other requirements contained in this
ordinance.
4.1 Hydraulic Capacity
The hydraulic capacity of a storm sewer must be determined using Manning's
Equation.
4.2 Minimum Size
The minimum diameter of a storm sewer must be twelve (12) inches. An orifice plate
or other device must control rate of release for detention storage, subject to approval of
the Board, where the twelve (12) inch pipe will not limit the rate of release as required.
4.3
4.4
4.5
Grade
The minimum and maximum allowable sewer gradients are those capable of producing
velocities of two(2) and fifteen (15) feet per second, respectively, when the sewer is
flowing full. A minimum of two (2) feet of cover is to be maintained over the top of
the pipe. Pipe cover less than the minimum may be used only upon approval of the
Board. Uniform slopes must be maintained between structures. A final grade must be
set with full consideration of the dapacity required, sedimentation problems, and other
design parameters.
Alignment
In general, a storm sewer must be straight between structures. The Board may allow
curved sewers at its discretion under certain conditions.
Manholes
Structures must be installed to provide access to continuous underground storm
sewers for the purpose of inspection and maintenance. Manholes must be
provided at the following locations:
1. Where two (2) or more storm sewers converge;
2. Where pipe size changes;
3. Where a change in alignment occurs;
4. Where a change in grade occurs;
5. At suitable intervals in straight sections of sewer, and
6. Wherever pipe materials change.
B. The maximum distance between storm sewer manholes must be as follows:
Size of Pipe Maximum Distance
(inches) (feet)
12" thru 42"
400
48" and larger 600
4.6
Inlets
Inlets or drainage structures must be utilized to collect surface water through grated
openings and convey it to storm sewers, channels or culverts. The inlet grate opening
provided must be adequate to pass the design ten (10) year flow with fifty (50) percent
of sag inlet grate open areas clogged. An overload channel from sag inlets to a suitable
outlet or basin must be provided. (See Section 3.5.1)
4.7 Workmanship
The specifications for the constructions of storm sewers cannot be less stringent than
those set forth in the latest revision of the Indiana Department of Transportation's
"Standard Specifications".
4.8 Materials
Storm sewer manholes and inlets must be constructed of cast in place concrete or
precast reinforced concrete. Material and construction must conform to Indiana
Department of Transportation's "Standard Specifications", Section 720. Pipe and
fittings used in storm sewer construction must be reinforced concrete pipe (ASTM C-
76). Smooth-walled PVC pipe and smooth walled corrugated polyethylene pipe may be
used only in areas specially approved by the Board. Smooth-walled PVC pipe and
smooth walled corrugated polyethylene pipe cannot be used under streets or as
driveway culverts. Other types of inlets, end treatments, pipes and fittings may be
used only when specifically authorized by the Board. Pipe joints must be flexible and
soil tight and must conform to the requirements of Section 715.02 Materials, of the
latest edition of the Indiana Department of Transportation's "Standard Specifications".
Pipe end treatments must be metal end sections for plastic pipes and concrete end
sections for concrete pipes.
4.9 Pipe Bedding, Backfill and Surface Restoration
All pipe must be bedded on four (4) inches and covered by twelve (12) inches of
Indiana No. 57 crushed limestone.
Where pipe is installed in earth areas, not immediately adjacent to a street or
road, the remainder of the trench must be hackfllled with selected earth
materials, humped over the trench to alloTM for settling.
Where pipe is installed in a graveled area, the remainder of the trench must be
backfilled with Bank Run sand to a point eight (8) inches below original grade
and then filled with Indiana No. 73 crushed limestone to original grade.
fn:8708\s~s~°'a°ctsm] 18
Where pipe is installed in an asphalt street, driveway, or parking area, the
remainder of the trench must be backfilled with Bank Run sand to a point nine
(9) inches below original grade. The trench must then be trimmed back six (6)
inches on each side and filled with 3000 psi concrete. After all construction is
completed, the trench must be cleaned, primed and paved with a one (1) inch
compacted thickness of INDOT HAC Surface to be flush with the surrounding
area. All patch seams can only be saw cut, cut smooth, straight and tarred.
Where pipe is installed in a concreted area, the remainder of the trench must be
backfilled with Bank Run sand to a point nine (9) inches below original grade.
The trench must then be trimmed back six (6) inches along each side and filled
with 3000 psi concrete flush with original grade. All patch seams must be saw
cut only, smooth and straight.
All cutting of trenches in existing asphalt or concrete pavements must be done
with a saw only to provide a straight, smooth joint when new paving is done.
4.10 Special Hydraulic Structures
Special hydraulic structures such as siphons, stilling basins, or other special structures
required to control the flow of water in storm drainage facilities, must be limited to
those locations justified by prudent planning and designed with careful and thorough
hydraulic engineering analysis.
CHAPTER 5
OPEN CHANNEL DESIGN STANDARDS
All open channels, whether constructed on public or private property, must conform to the
design
standards and other requirements contained in this Ordinance.
5.1 Channel Cross Section and Grade
The required channel' cross section and grade are determined by the design capacity
based on Maiming's Equation, the material in which the channel is to be constructed,
and the requirements for maintenance. A minimum depth may be required to provide
adequate outlets for subsurface drains, storm sewer pipes, tributary ditches or streams.
The channel grade must be such that the velocity in the channel is high enough to
prevent siltation but low enough to prevent erosion. Channel lining materials must be
justified by the project engineer in the final drainage design.
5.2 Side Slopes
5.3
Side slopes of earthen channels must be no steeper than three to one (3:1), justified by
local materials and approved by the Board. Flatter slopes may be required to prevent
erosion and for ease of maintenance. Where channels will be lined, as per Section 5.7,
side slopes must be no steeper than one and one/half to one (11/2:1) with adequate
provisions made for weep holes. Side slopes steeper than one and one/half to one
(11/2:1) may be used for lined channels provided that the side lining and structural
retaining wall are designed and constructed with provisions for live and dead load
surcharges.
Channel Stability
A stable channel does not vary design gradient and cross section from
acceptable limits;
Channel stability must be determined for an aged condition. The velocity must
be based on the design flow or the bank full flow, whichever is greater, using
"n" values for various channel linings; and
Channel stability must be checked using conditions immediately after
construction for justification of erosion control measures. See Chapter Seven,
"Soil Erosion and Sedimentation Control", for erosion control standards.
5.4 Drainage of Open Channels
Vegetated channels with a gradient of less than one percent (1.0%) or that are subject
to low flows of long duration or where wet conditions prevail must be drained with a
tile system or by other means such as paved gutters. Tile lines may be outletted
through a drop structure at the end of the channels or through a standard tile outlet.
Tiles must be bedded in granular materials that will not pass through tile openings.
Tiles must be installed with a minimum of six (6) inches of cover over the top of the
tile and must be offset from the centerline of the channel.
5.5 Appurtenant Struct/~res
The channel design will include the design of all structures required for the proper
functioning of the channel, the laterals, and the maintenance ways.
fn: 8708\sdese°'d°c[srnl 20 '
5.6 Disposition of Spoil Material
Spoil material resulting from clearing, grubbing, and channel excavation must be
disposed of in a manner that will minimize erosion and other adverse effects to
easements, surface drainage, and rights-of-way. Disposal must be done in a manner
that will also improve the aesthetic appearance of the site.
5.7 Materials
Materials acceptable for use as channel lining are concrete, gabions, pegged rod
erosion control blankets, and netting.
Other lining materials require specific approval of the Board. All channel materials
must comply with the latest edition of the Indiana Department of Transportation's
"Standard Specifications". Interconnected tires are not acceptable material.
CHAPTER 6
STORM WATER DETENTION
The following governs the design of any improvement with respect to the detention of storm
water runoff.
6.1 Acceptable Detention Methods
The increased storm water runoff from a proposed development must be detained on-
site by appropriate wet or dry bottom reservoirs, by storage on flat roofs, parking lots,
streets, lawns or other acceptable techniques. Measures that retard the rate of overland
flow and the velocity in runoff channels may also be used to control the runoff rate.
6.2 Detention Facility DeSign
Storm water facilities must be designed to store the excess flows from a post
development one hundred (100) year return interval storm. The release rate must be
that of a ten (10) year return interval storm on the site in its predeveloped state or the
capacity of the receiving stream, whichever is less. The developer's engineer is
responsible for determining the hydraulic capacity of the receiving stream
6.3 Allocation of detention
In the case of an existing limiting restriction that cannot be realistically removed, the
allowable release rate from any one detention basin must be in direct proportion to the
ratio of its drainage area to the drainage area of the entire water shed upstream of the
limiting restriction. The total runoff must not exceed the capacity of the restriction and
each development must be responsible for its proportionate share of the storage
requirement.
6.4 Determination of Storage Volume - Rational Method
For areas of two hundred (200) acres or less the Rational Method may be used to
determine the required volume of storm water storage, as outlined in the Cdunty Storm
Drainage Manual of the Highway Extension and Research Project for Indiana Counties
and Cities (HERPICC)
6.5 Determination of Storage Volume - Other Methods
6.6
Methods for determining runoff and routing of storm water other than the Rational
Method may be used to determine the storage volume required to control storm water
runoff. The procedures or methods used must receive the prior approval of the Board.
The TR-20 and TR-55 models are approved for appropriate use in analysis of the
runoff and routing of storm water.
General Detention Basin Design Requirements
Basins must be constructed to temporarily detain the storm water runoff that exceeds
the peak flow rate authorized by this ordinance. The following minimum standards
must be observed:
The maximum volume of water stored and subsequently released at the design
release rate must not result in a storage duration in excess of forty-eight (48)
hours unless additional storms occur within the period;
All storm water detention facilities must be separated by not less than twenty-
five (25) feet from any building or structure to be occupied, and the lowest floor
of any building or structure must be at least two (2) feet above the one-hundred
(100) year storm water elevation of detention facilities;
Safety grates may be required on all outlet control structures. Grates must
retain a sphere greater than six (6) inches in diameter and must have a screen
area at least six (6) times the end area of the outlet control structure;
Danger signs must be mounted at appropriate locations to warn of deep water,
possible flooding conditions during storm periods and other dangers that exist.
Fencing must be provided if deemed necessary by the Board. The Board
must approve design and locations.
Outlet control structures must be designed to operate as simply as Possible and
must require little or no maintenance and attention for proper operation;
Emergency overflow facilities such as a weir or spillway must be provided for
the release of exceptional storm runoffs or in emergency conditions such as the
normal discharge devices becoming totally or partially inoperative. The
overflow facility must be of such design that its operation is automatic and does
not require manual attention; and
7. Side slopes must be in compliance with Section 5.2.
6.7 Dry Bottom Detention Basin Design Requirements
Dry Bottom Detention Basins must comply with the following additional requirements:
Provisions must be incorporated to facilitate complete interior drainage of dry
bottom detention basins. Acceptable methods include natural grades to outlet
structures, longitudinal or transverse grades to perimeter drains, paved gutters,
or subsurface drains. Dry bottom detention basins with less that one percent
(1%) gradient must be provided with subsurface drainage or paved gutters;
2. Recreational facilities, aesthetic qualities, open space or other secondary use
- must be considered in planning the detention facility; and
The maximum planned depth of storm water Stored without a permanent pool
must not exceed four (4) feet.
6.8 Wet Bottom Retention Basin Design Requirements
Where part of a detention basin, excluding wetlands, Will contain a permanent pool of
water, the following additional requirements apply:
If fish are to I/e maintained, a pond must have a water area of at least one/half
(1/2) acre and a minimum depth of approximately ten (10) feet must be
maintained over at least twenty-five (25) percent of the pond area. The
remaining pond area must not have extensive shallow areas, except as required
by subsection (3) below;
If fish are not to be maintained, a minimum depth of eight (8) feet must be
maintained over at least twenty-five (25) percent of the pond at permanent water
level. Where a limiting layer prevents excavation to that depth, a minimum of
six (6) feet over at least fifty (50) percent of the area is required;
In excavated ponds, the underwater side slopes in the pond must be stable. In
the case of valley storage, natural slopes may be considered to be stable;
A safety ledge a minimum of six (6) feet in width and a 10:1 slope is reqUired
and must be installed in all ponds approximately thirty (30) inches below the
permanent water level; and
Erosion control measures must be installed to prevent erosion from wave action
and wet-dry cycles;
Chain-link fencing must be provided around the perimeter of the wet bottom
retention basin. The minimum fence height must be six (6) feet.
6.9 Rooftop Storage
If rooftop detention is proposed, details of such designs are to be included in the
Improvement Location Permit application and must,include the depth and volume of
storage, details of outlet devices and down drains, and elevations of emergency
overflow provisions. Rooftop detention is not recommended.
6.10 Parking Lot Storage
Paved parking lots may be designed to provide temporary detention storage of storm
water. Ponding should, in general, be confined to those positions of the parking lots
farthest from the area served. Ponding areas must not conflict with handicapped
parking and access routes. Such ponding areas should be exposed to sunlight in winter
months to minimize icing. Storage depth must be linfited so as not to conflict with
parking lot use. Any detention facility utilizing a parking lot must take resurfacing and
other parking lot maintenance activities into consideration during design.
6.11 Facility Maintenance Responsibility
Maintenance of draixiage facilities during construction must be the responsibility of the
land developer. Maintenance responsibilities must be documented by appropriate
restrictive covenants to property deeds prior to final drainage plan approval. Routine
maintenance is the developer's responsibility for a minimum of five (5) years after
completion of the drainage facility. After that time, upon the approval of the City
Engineer, the City may accept responsibility for routine maintenance of the drainage
facility. The permanent pool of a wet bottom basin is the responsibility of the
developer or homeowner's association. Routine maintenance must, at a minimum,
assure that the drainage facility performs the functions for which it was designed and
constructed. Unless specifically accepted by the City, all drainage facilities must be
privately owned and funded.
6.12 Joint Development of Control Systems
Storm water control systems may be planned and constructed jointly by two (2) or
more developers as long as compliance with this ordinance is maintained.
6.13 Allowance for Sedimentation
Dry bottom detention basins and wet bottom retention basins must be designed with an
additional six percent (6 %) of available capacity to allow for sediment accumulation
resulting from development and to permit the pond to function for reasonable periods
between cleanings. Basins should be designed to collect sediment and debris in specific
locations so that removal costs are kept to a minimum.
6.14 Detention Facilities in a Flood Plain
If detention storage is provided within a floodplain, only the net increase in storage
volume above that which naturally existed in the floodplain must be credited to the
development. No credit will be granted for volumes below the elevation of the
regulatory flood at the location unless compensatory storage is also provided.
CHAPTER 7
SOIL EROSION AND SEDIMENT CONTROL
7.1 General Provisions
Measures taken to control erosion and sedimentation must assure that sediment is not
transported from a site by storm events. The following general provisions should be
used in the preparation of submissions required under this ordinance:
To minimize potential for soil erosion, development should fit the topography
and soils of the site. Steep slopes, deep cuts, and fills in er0dible soils should
be avoided wherever possible and natural contours should be followed as
closely as possible;
.Natural vegetation must be retained and protected wherever possible. Areas
~mmediately adjacent to natural watercourses and protected wetlands must also
be left undisturbed wherever possible. Vegetation to be preserved must be
protected prior to construction;
All activities on a site must be constructed in a logical sequence so that the
smallest practical area of land will be exposed for the shortest practical period
of time during development;
Practices including, but not limited to, sediment basins, silt traps or filters must
be installed prior to land-disturbing activities and maintained to remove
sediment from runoff leaving the site as long as unstabilized soil conditions
exist;
The selection of soil erosion and sediment control measures must include the
assessment of the probable frequency of climatic events. The aesthetics of the
project improvements and the requirements of continuing maintenance must be
considered; and
Provisions must be made to accommodate the increased runoff caused by
changes in soil and surface conditions during and after developments. Drainage
ways must be designed so that their final gradients and resultant velocities will
not create erosion.
7.2 Design Criteria, Standards, and Specifications for Erosion Control Measures
All erosion control measures must meet the design criteria, standards, and
specifications outlined in the:
a) The "Field Office Technical Guide" of the Soil Conservation Service (SCS of the
United States Department of Agricultural (USDA)); and
b) The "Urban Development Planning Guide" of the Hoosier Heartland Resource
Conservation and Development Council; and
c) The "Indiana Handbook for ErOsion Control In Developing Areas" Of th~ iDNR_
Division of Soil Conservation.
These publications are available through the Clark County Soil and Water Conservation
District, the Natural P~esource Conservation Service (NRCS) offices, the U~S.
Government Printing Office, and the IDNR Division of the Soil Conservation. Erosion
control measures must be identified on the plans using standard symbols (See Appendix
A).
7.3 Maintenance of Erosion Control Measures
The applicant or subsequent landowner must maintain all sediment basins and other
erosion control measures necessary to meet the requirements of this ordinance. After
land-disturbing activities cease, and the silt is stabilized, temporary sediment basins and
other temporary erosion control measures may be eliminated if their purpose has been
fulfilled. Any disturbed soil resulting from removal of such practices must be
stabilized by approved methods.
7.4
Control of Erosion and Sediment during Land Disturbing Activities
The following requirements must be met on all sites:
Sediment Trapping: Temporary sediment basins or other suitable control
measures must detain sediment-laden water flowing from the site. Water may
not be discharged in a manner that causes erosion of the site or receiving
channels or an accumulation of sediment within the receiving channel or its
outlets;
Waste and Materials Disposal: All waste and unused building materials
including, but not limited to, garbage, debris, cleaning wastes, wastewater,
toxic materials, and hazardous substances must be properly disposed of and not
allowed to be carried by runoff into a receiving channel or storm sewer system;
Tracking: Prior to the land-disturbing activity each site must have graveled
access drives or other approved systems of sufficient width and length to
eliminate sediment being tracked onto public or private roadways. Gravel
access drives must be maintained by acceptable methods. Flushing is not an
acceptable method;
TemPorary Stream Crossings: A stream crossing during land-disturbing
activities must be non-erosive and structurally stable and must not contribute to
flooding or safety hazards. Streams should be crossed at right angle to the
stream flow. Erosion control measures must be employed and must be
appropriate tO the expected life of the crossing. Temporary crossings must
convey bankfull flow or a two (2) year peak discharge, whichever is less.
Overflow areas must be protected from erosion for a ten (10) year peak flow;
Sediment Removal: Public or private roadways must be cleaned daily and after
major storms using acceptable methods to remove any accumulated sediment.
The developer's contractors are responsible for supervision of the construction
activity within the development and must take all necessary actions to remove
sediment from the streets. Appreciable sediment should be replaced and
stabilized properly and protected from redeposit onto the road or into the storm
water system;
Drain Inlet Protection: All storm drain inlets must be protected with straw
bales, filter fabric, or equivalent barriers meeting accepted design criteria,
standards and specifications. Curb inlet protection measures that trap sediment
within pavement areas are prohibited; and
Site Erosion And Sediment Control: The following items apply only to the time
period when land disturbing activities are taking place which may cause water
and sediment to leave the site:
(a)
Runoff passing through the site from adjacent areas must be minimized
by protecting the existing channel or, if necessary, diverting it around
disturbed areas if legal, feasible, and practical; and
(b)
On the site, runoff from the entire disturbed area must be controlled by
meeting the following:
(1)
(2)
All disturbed ground left inactive for seven (7) or more days
must be stabilized by seeding, sodding, mulching, or by other
equivalent erosion control measures;
For sites having less than ten (10) acres disturbed at one time, silt
fences, straw bale dams, or equivalent erosion control measures
must be placed along all sloping perimeters where erosion and
sedimentation could occur. If a channel or an area of
concentrated runoff passes through the site, silt fences must be
placed along the channel edges to reduce the amount of sediment
reaching the channel; and
(3)
Where drainage acres are too large or runoff volumes are too
great for sediment trapping practices, one or more sediment
· basins should be constructed. Each sediment basin should have a
'sufficient depth and a sufficient surface area to trap the sediment.
The discharge rate or velocity from a basin should be
sufficiently low so as not to cause erosion or the receiving
channel must be adequately protected.
~: During cut and fill operations toPsoil must be stockpiled
and re-spread on final grades where vegetation is tO be establishedl
Soil Stockpiling: Excess soil that is stored to be used at a later date must be
stockpiled and protected from erosion.
8.1 Sump Pumps
CHAPTER 8
ACCESSORY DRAINS
Sump pumps installed to receive and discharge ground waters or other storm water
must be connected to a storm sewer, a subsurface drain or a designated storm discharge
channel. Floor drain flow or other sanitary sewage must be connected to the sanitary
sewers or septic systems and must not discharge to storm sewers or surface outlets.
8.2 Down Spouts
All down spouts or roof drains must discharge onto the ground or be connected directly
to the storm sewer pipe. Down spouts or roof drains must not be connected to the
sanitary sewers or subsurface drains.
8.3 Footing Drains
8.4
Footing drains must be connected to a storm sewer, subsurface drain or designated
storm drainage channel. Footing drains or drainage tile must nOt be connected to the
sanitary sewer or septic system.
Basement Floor Drains
Basement floor drains must be connected to the sanitary sewers or septic system.
Basement drains must not be connected to sump pumps that discharge to storm sewers.
