Stormwater Management Plan
1.0 SITE DESCRIPTION
1.1. Introduction
This report represents the Stormwater Management Plan for construction of the
Pickleball Ventures - Pickleball Facility. It was prepared to meet the regulatory
requirements of the City of Fort Collins Stormwater Criteria Manual as well as the
Colorado Department of Health, Water Quality Control Division in compliance with
the provisions of the Colorado Water Quality Control Act, and the Federal Water
Pollution Control Act.
This plan serves as a consolidated document for information on water quality
protection for the subject site and areas immediately adjacent. It should also be
noted that this plan is a living document that will need to be updated and maintained
throughout the construction process. The intent of this plan is to provide the
contractor a tool to consolidate records, logs, permits, applications, etc. as well as
guidance on water quality protection. The plan incorporates elements that can be
found in the contract plans and specifications as well as in the City of Fort Collins
Stormwater Criteria Manual.
1.2. Current Conditions
The Pickleball Ventures - Pickleball Facility is located in the southeast Quarter of
Section 31, Township 7 North, Range 68 West of the Sixth P.M. City of Fort Collins,
County of Larimer, State of Colorado. More specifically, the Pickleball Facility is a 4.37
ac. piece of property that is developed with a parking lot and warehouse structure,
and is zoned as incorporated land.
The site generally drains east to west at a 0.5%-1.5% slope, and is roughly over 90%
impervious area, including 1.37 acres of the building footprint. The drainage onsite to
the north and west generally sheet flows on the impervious areas to off and around
the site in existing drainage ditches, and into the Golden Meadows detention and
water quality pond offsite to the north in Golden Meadows Park. Flows to the south
and east are captured in a ditch and sent through a storm drain to the north into the
same offsite detention pond in Golden Meadows Park.
1.3. Nature and Purpose of Construction
The proposed site and its improvements are a portion of Lot 19 of the Golden
Meadows Business Park, bounded to the north by Golden Meadows Park and the
Golden Meadows detention and water quality pond, and is bound to the east by the
existing Union Pacific Railroad. To the south the site borders Colorado Early Colleges
Fort Collins High School, and to the west the site is bordered by Kruse Elementary
School.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
The existing 60,038 sf structure on site will remain, and will be separated into two
structures internally, roughly the west half of the building will be dedicated to the
Pickleball Facility, and the east half will be used for continued industrial purposes.
Additionally, the existing parking lot surrounding the structure to the east, south and
west will be largely resurfaced and repainted, with sections being removed entirely
for the purposes of building outdoor pickleball courts to the west of the structure. The
total disturbed area rounds out to be nearly 4.61 acres.
1.4. Wetlands and Receiving Waters
The site is located in the Fox Meadows Basin, which is a mostly residential developed
basin in Fort Collins. There are no wetlands on site, and there are no mapped
floodplains for the site.
1.5. Rainfall Erodibility & Erosion Sediment Control Methods
Attached at the end of this report are a series of drawings that describe the proposed
site conditions, as well as the locations of the erosion control Best Management
Practices (BMPs). The Erosion Control Plan depicts the anticipated drainage patterns
after grading activities and the anticipated locations for BMPs such as construction
fences, inlet protections, and stabilized staging areas. It has been assumed that the
majority of the surrounding areas will remain in their present state during the
construction of this project.
The Contractor will be responsible for implementing and maintaining the erosion and
sediment control measures described in the document and the accompanying design
drawings. The Contractor may designate these tasks to certain subcontractors as seen
fit, but the ultimate responsibility for implementing these controls and their proper
function at each phase of the project remains with the Contractor. Due to the sites
proximity to existing commercial parking, the contractor will be responsible for
thorough site cleanup day to day. The order of major activities will be as follows:
1.Install vehicle tracking control and other perimeter soil erosion control
measures.
2.Clear and rough grade for improvements.
3.Excavate and install improvements including underground piping and
drainage structures.
4.Fine grading.
5.Final stabilization.
6.Clean up.

1.6. Non-Stormwater Discharge
Non-stormwater discharges will be eliminated or reduced to the fullest extent
feasible. This plan does not cover construction dewatering. Pumping or draining
groundwater that has infiltrated into an excavation requires a general permit for
construction dewatering, regardless of the size of the project. Stormwater that mixes
with groundwater in an excavation is also subject to the controls in the general permit
for Construction Dewatering.
No materials shall be discharged in quantities that will have an adverse effect on the
receiving waters. The measures listed below will be implemented to achieve these
objectives.
Proper and lawful disposal of all waste materials.
Control any spills and leaks that may occur and clean up (mitigate).
Use of designated areas for equipment repair and cleaning.
Careful application of irrigation water.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
All potential materials and pollutants used during construction other than sediment
which have the potential to impact storm water quality will be stored, managed, used
and disposed of, and will be handled and disposed of in a manner that does not
contaminate and minimizes the potential for releases to the environment, especially
storm water.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
2.0 STORMWATER MANAGEMENT CONTROLS
2.1. Controls Overview
During construction, several controls and measures shall be implemented under the
direction of the General Contractor to prevent offsite discharge of contaminated
storm water. Controls for this project include erosion, sedimentation, stabilization,
and other BMPs. Specifications and engineering drawings for the selected BMPs can
be found in Appendix B of this report.
The contractor shall comply with the attached plans and guidelines as a minimum.
Field conditions and unforeseen circumstances will dictate modifications or additions
to this Stormwater Management Plan. Where storm water pollution potential exists,
appropriate preventative measures (BMPs) must be utilized and documented,
regardless of the status of those measures having been identified in this report or not.
2.2. Erosion and Sediment Controls
The purpose of erosion control on this site is to prevent construction-induced soil
movements. Conversely, sediment control methods are used to capture soil that has
been disturbed despite the erosion control measures. It is recognized that despite
necessary prevention, some sediment may still enter into runoff on the site, but
proper implementation of these methods can help reduce the impacts erosion and
sediment movement.
The BMPs scheduled for use during the construction of this site can be divided into
Structural and Non-Structural Practices. Section 2.2.1 of this report discusses the
proposed structural BMPs to be utilized. Section 2.2.2 discusses the non-structural
practices.
2.2.1.Structural Practices (See drawings for locations)
Structural BMPs are site management practices that will minimize erosion and
sediment transport. Such practices may include using straw bales, silt fences, drainage
swales, inlet protections, outlet protections, etc. to protect areas downstream of the
site from turbid water, sediment, oils and other contaminants, which may mobilize
during storm water flows. The structural BMPs that may be utilized on the subject site
are depicted in the Drainage and Erosion Control Plan and are described below:
Silt Fence:
A temporary vertical barrier of filter fabric attached to and supported by posts
and entrenched into the ground.
Utilized to intercept sediment from disturbed areas during construction
operations and to filter shallow sheet flow.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
Typically used along the toe of fills, in transition areas between cut and fills,
and adjacent to streams.
Generally installed prior to or immediately following land-disturbance activity.
Shall be inspected periodically and after each rain or snowfall event and
repaired when necessary. Sediment shall be removed from behind the fence
when it accumulates to one-half the exposed fabric height and properly
disposed of.
Inlet Protection:
A temporary barrier used across or around a storm drain drop inlet, a curb
inlet, or a culvert inlet.
Utilized to intercept and filter sediment-laden runoff and prevent it from
entering storm drainage systems.
Not to be utilized in place of a sediment-trapping device. Used as a secondary
control device.
Do not use where ponded water might flow onto the roadway.
Blocking of the inlet should not be watertight.
Generally installed prior to land-disturbance activity on existing inlets and
immediately after the construction of new inlets.
Shall be inspected periodically and after each rain or snowfall event and
repaired when necessary. Accumulated sediment shall be removed and
properly disposed.
Grading Techniques:
Soil surface roughening, terracing and rounding at tops of cuts, transitions and
roadway ditches can be used to facilitate plant establishment and minimize
erosion.
Utilized to temporarily stabilize disturbed areas and protect from wind and
water erosion after grading activities have ceased during construction.
Inspection and maintenance must be provided periodically and after each rain
or snowfall event that causes runoff to ensure roughened state is maintained.
Rills developed should be filled and the area re-graded immediately.
Erosion control measures are the responsibility of the General Contractor to inspect
and maintain. Any existing erosion control devices that are removed in order to
complete the construction of the utilities shall be replaced immediately following the
construction that required its removal unless directed otherwise by the construction
plans.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
2.2.2.Non-Structural Practices (See drawings for locations)
Non-Structural BMPs are both interim and permanent stabilization practices. Such
practices may include temporary seeding, permanent seeding, mulching, geotextiles,
sod stabilization, vegetative buffer strips, tree protection, preservation of mature
vegetation, etc. The non-structural BMPs that may be utilized on the subject site are
described in more detail below:
Temporary and Permanent Seeding:
Soil preparation, seeding, mulch tackifier and/or mulching shall be required
for all disturbed areas that are not surfaced.
Exposed soils which are not part of the active grading and/or construction
activity shall be stabilized.
Seeded areas shall be inspected frequently. If the seeded areas fail to
establish, provide adequate ground coverage. If seeded areas are disturbed,
the area should be re-seeded.
Permanent landscaping and vegetative cover are depicted on the Landscaping
plans.
Mulching:
Mulching is the application of plant residues to the soil surface. Typical
mulching material includes wood cellulose fiber and certified weed free hay or
straw, certified under the Colorado Department of Agriculture Weed Free
Forage Certification Program as regulated by the Weed Free Forage Act, Title
35, Article 27.5, CRS.
Utilized in combination with mulch tackifier for temporary erosion control
(i.e., incomplete slopes, detour slopes, stockpiles, or seasonal constraints).
Used to cover permanent or temporary seed areas. Hydromulch shall not be
done in the presence of free surface water.
Inspect frequently and reapply mulching in areas where the mulching has been
loosened or removed. Mulch tackifier must be applied with additional
applications of mulching.
Mulch Tackifier:
An organic soluble powder adhesive used as a water slurry to adhere native
hay, straw, hydromulch, or seeding to a surface and together.
Used to cover disturbances as temporary cover for wind erosion.
Mulch movement indicates poor application and procedure mixture. Proper
application will bond mulch material together and to the soil.
Inspect by touching mulch surface to determine if adhesion has occurred.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
Maintain Existing Vegetation:
Existing vegetation should be preserved and inspected regularly where
possible to prevent the migration of sediment.
Establish and maintain buffers for existing vegetation.
Areas beginning to show signs of erosion or soil transport may require
additional emergency BMPs.
2.2.3.Other Controls (See drawings for location)
Vehicle Tracking Control / Construction Entrance:
A temporary stabilized layer of aggregate underlined with geotextile or gravel
located where traffic enters or exits the construction site.
The structure shall be constructed prior to any construction activity and
maintained daily.
Stone shall be added and repairs performed as conditions require.
When mud is present and not easily removed by a tracking pad, tire washing
should be implemented as needed. Tire washing operations should occur near
the construction exit on a stabilized stone pad. Implementation of a tire
washing area should include provisions for collecting wash water and directing
it to an onsite pond.
Tracking of Sediment onto Roads, Streets and Parking Lots:
Public and private roadways and parking shall be kept clear of accumulated
sediment. Bulk clearing of accumulated sediment shall not include flushing the
area with water. Sediment will be shoveled and or swept from the street and
disposed of in a manner that prevents contamination of storm water or
surface water runoff.
2.3. SWMP Administrator
Implementation and management of the environmental aspects of this project under
this SWMP report are the responsibilities of the General Contractor. The General
Contractor shall ensure the all contractors providing services on the project have
access to a copy of the SWMP report and appropriate training regarding storm water
pollution prevention. The General Contractor, Building Contractor, Utility Installations
Contractor, Grading Contractor and all other contractors and subcontractors shall be
familiar with the SWMP report and their responsibilities on the plan.

2.4. Materials Management
2.4.1.Potential Pollution Sources
It is anticipated that this construction project will not utilize any abnormal or atypical
hazardous materials. The construction site will operate much like other typical
construction projects. The following materials or substances are expected to be
present onsite during construction:
Concrete/Additives/Wastes Cleaning solvents
Detergents Petroleum based products
Paints/Solvents Pesticides
Acids Fertilizers
Solid and construction wastes Sanitary wastes
Soil stabilization additives
Activities on the site that may have an impact on stormwater include the following:
Equipment and/or vehicle washing
Fertilizers, chemicals, or other material storage
Vehicle maintenance or fueling
Waste incineration, treatment, storage or disposal
Off-site vehicle tracking
Loading/unloading areas
Concrete truck washout
As construction progresses, specific areas shall be designated for vehicle maintenance
and refueling, material and waste storage, construction equipment staging, and
bathroom facilities. Management measures and procedures for these facilities are
discussed later in the plan.
2.4.2.Pollution Prevention Measures
Pollution prevention measures shall be utilized to prevent construction materials with
the potential of polluting stormwater, such as those listed above, from coming in
contact with runoff. Measures include good housekeeping and proper disposal of
construction and demolition debris, equipment fuel, lubricants, paints and solvents,
asphalt, concrete, topsoil and other materials, as well as controls which prevent
sediments from being tracked off-site by construction vehicles, and proper control of
any non-stormwater flows on-site.
Best Management Practices (BMPs) are schedules of activities, prohibitions of
practices, maintenance procedures, and other management practices to prevent or
reduce pollution of public waters. BMPs also control site runoff, spillage or leaks,
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
sludge or waste disposal, or drainage from raw material storage. With regard to
construction, these may include structural controls and nonstructural practices that
are designed to prevent pollutants from entering water or direct the flow of water
away from potential sources of pollution.
For construction sites, there are three main types of BMPs: those that prevent erosion
and sediment transport, others that prevent pollutants from construction materials
from mixing with stormwater, and those that trap pollutants before they can be
discharged. BMPs for most common construction materials and wastes with the
greatest potential for adversely affecting stormwater quality are as follows:
BMPs for Disturbed and Stored Soils:
Soil preparation, seeding, mulch tackifier and/or mulching shall be required
for all disturbed areas that are not surfaced.
Exposed soils, which are not part of the active grading and/or construction
activity, shall be stabilized.
Seeded areas shall be inspected frequently. If the seeded areas fail to
establish, provide adequate ground coverage. If seeded areas are disturbed,
the area should be re-seeded.
Permanent landscaping and vegetative cover are depicted on the Landscaping
plans.
BMPs for Vehicle Tracking of Sediment:
Use vehicle tracking pads at the entrances of construction.
o A temporary stabilized layer of aggregate underlined with geotextile or
gravel located where traffic enters or exits the construction site.
Public and private roadways shall be kept clear of accumulated sediment. Bulk
clearing of accumulated sediment shall not include flushing the area with
water. Sediment will be shoveled and or swept from the street and disposed
of in a manner that prevents contamination of storm water or surface water
runoff.
The structure shall be constructed prior to any construction activity and
maintained daily.
Stone shall be added and repairs performed as conditions require.
When mud is present and not easily removed by a tracking pad, tire washing
should be implemented as needed. Tire washing operations should occur near
the construction exit on a stabilized stone pad. Implementation of a tire
washing area should include provisions for collecting wash water and directing
it to an onsite pond.

o If a container does spill, provide cleanup immediately.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
Plan for additional containers and more frequent pickups during the
demolition phase of construction.
Make sure that construction waste is collected, removed, and disposed of only
at authorized disposal areas.
Check with local solid waste management agency for specific guidance.
Trash, debris and spoils shall be properly contained at the end of each day.
BMPs for residual Concrete disposal:
Emptying or wash out of excess concrete may be allowed on site. Excess
concrete and wash water should be disposed of in a manner that prevents
contact between these materials and stormwater discharges from the site.
Residual concrete shall be discharged in specifically designated dike areas,
which have been prepared to prevent contact between the concrete and/or
washout and stormwater discharged from the site and/or ground water.
The hardened residue from the dike areas shall be disposed of in the same
manner as other non-hazardous construction waste materials or may be broke
up and utilized as deemed appropriate by the contractor.
The use of the washout area shall be temporary (less than one year).
Washing of trucks and masonry equipment is to be performed only at a
designated concrete washout. Do not bury wastes.
BMPs for Sanitary/Septic Wastes:
Sanitary or septic wastes that are generated onsite should be treated or
disposed of in accordance with State or local requirements.
If self-contained/temporary facilities are utilized, the domestic waste haulers
should be contracted to regularly remove the sanitary and septic wastes and
to maintain the facilities in good working order.
Any facilities to be connected to a sanitary sewer system should be properly
hooked to the sanitary sewer system to prevent illicit discharges.
Untreated, raw sewage should never be discharged or buried onsite.
Contact local government and state regulatory agencies to ensure the
compliance with state or local requirements.
If sewage is being discharged to the sanitary sewer, the local treatment works
authority should be contacted.
BMPs for Pesticides:
Store pesticides in a dry covered area and elevate above the ground.
Provide curbs or dikes to contain possible spills.
Have measures on site to contain and clean up spills.
Strictly follow recommended application rates and recommended application
methods.

BMPs for Fertilizers/Detergents:
Fertilizers and detergents shall be stored in dry and covered area and elevated
above the ground.
o Berms shall be provided around the storage area to avoid contact with
stormwater runoff.
Limit the application of fertilizers to the minimum area and minimum
recommended amounts.
Reduce exposure of nutrients to storm water runoff by working the fertilizer
deep into the soil.
Hydro seeding, where lime and fertilizers are applied to the ground surface in
one application should be limited where possible.
Limit the use of detergents onsite: wash water containing detergents should
not be discharged to the storm system.
Implement good erosion and sediment control to help reduce the number of
fertilizers that can leave the site as well as sediments.
BMPs for Hazardous Wastes Disposal:
Check with local waste management authorities to determine what the
requirements are for disposing of hazardous materials, or often found on the
manufacturers recommended method, usually found on the label.
Use the entire product before disposing of the container.
Do not remove the original product label from the container. It contains
important information.
Do not mix products together unless specifically recommended by the
manufacturer.
2.5. Spill Management
Construction site supervisors should create and adopt a spill control plan that includes
measures and procedures to stop the source of the spill, contain the spill, clean up,
and to dispose of contaminated materials. The following measures would be
appropriate for a spill prevention and response plan:
Store and handle materials to prevent spills:
o Tightly seal potentially hazardous containers.
o Make sure all containers are clearly labeled.
o Stack containers neatly and securely.
o Where possible, store containers on pallets in a covered area.
Reduce stormwater contact if there is a spill:
o Have cleanup procedures clearly posted and cleanup materials readily
available.
o Stop the source of the spill.
o Contain any liquid and cover the spill with an absorbent material.
Dispose of contaminated materials according to manufacturer’s instructions
or according to state or local requirements.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
Identify personnel responsible for responding to a spill of toxic or hazardous
materials:
o Provide personnel spill response training.
o Post names of spill response personnel alongside cleanup procedures
postings.
Keep the spill area well ventilated.
Additionally, records of spills, leaks, or overflows that result in the discharge of
pollutants must be documented and maintained. Information such as the time and
date, weather conditions, response procedure taken, response personnel involved,
reasons for the spill, etc., shall be recorded for all occurrences in the Stormwater
Management Plan and on the site map. Spill Categories are as follows:
Minor Spills:
Any event that involves 5 gallons or more and involves the following:
o Less than the reportable quantity.
o Stays within the permitted area.
o Does not threaten any stormwater conveyances.
Significant Spills:
Report the quantity if it falls under the reportable quantities of spilled
materials (for more information, refer to SARA Title III List of Lists, which is
available from the EPA if necessary).
Report if any of the spilled materials leave the permitted area.
Spills where the spilled material threatens entering any water conveyances.
Hazardous Spills:
Any substance requiring an MSDS response.
Procedures included in hazardous spills can also include but are not limited to:
o Securing the area,
o Providing first aid, if necessary,
o And notifying emergency response personnel of the spill material,
observed symptoms, and any other necessary related information.
Some spills may need to be reported to the Division of Water Quality and the City of
Fort Collins immediately. Specifically, significant spills that are a release of any
chemical, oil, petroleum product, sewage, etc., which may enter waters of the State
of Colorado (which include surface water, ground water and dry gullies or storm
sewers leading to surface water), any spill that exceeds the reportable quantity, and
any amount that leaves the permitted area must be reported. The Division’s toll-free
24-hour environmental emergency spill reporting line is 1-877-518-5608. Written
documentation to both the Colorado Department of Health & Environment and the
City of Fort Collins of significant spills should be provided within 5 days.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
3.0 DRY LAND VEGETATION
3.1. Soil and Surface Conditions
The Pickleball Facility site consists of primarily Nunn clay loam. Nunn clay loam
belongs to hydraulic soil group C. The Nunn clay loam generally has slopes ranging
from 1-3% in wet conditions to 3-5%. The soil at the site is moderately well to
somewhat poorly drained, and has a texture that retains moisture but has slower
permeability.
3.2. Seed Mixes
A standard City of Fort Collins seed mix should be used for the site. If a standard mix
is not used than a request to the city must be submitted of the preferred seed mix
alongside the desired the application rates.
3.3. Mulches
Typical mulching material includes certified weed free hay or straw, certified under
the Colorado Department of Agriculture Weed Free Forage Certification Program as
regulated by the Weed Free Forage Act, Title 35, Article 27.5, CRS and wood cellulose
fiber. Mulch should be utilized in combination with mulch tackifier for temporary
erosion control (i.e., incomplete slopes, detour slopes, stockpiles) when seeding is not
allowed due to seasonal constraints. Mulch is also used to cover permanent or
temporary seed areas. The mulch should be inspected frequently and reapplied in
areas where the mulch has been loosened or removed. Mulch tackifier must be
applied with additional applications of mulching.

5.0 INSPECTION AND MAINTENANCE
5.1. Inspection and Maintenance Overview
A site inspection of all erosion control facilities shall be conducted at least once every
two weeks and immediately following any significant precipitation or snowmelt event
that could cause surface erosion and every 30 days for inactive construction projects.
The inspection must determine if there is evidence of, or the potential for, pollutants
entering the drainage system, and BMPs should be reviewed to determine if they still
meet the design and operational criteria in the SWMP report and that they continue
to adequately control pollutants at the site. The construction site perimeter, disturbed
areas, discharge points and areas used for material storage that are exposed to
precipitation shall be inspected for evidence of, or the potential for, pollutants
entering the storm drainage system. Erosion and sediment control measures
identified in this SWMP report and within the construction plans shall be observed to
ensure that they are operating correctly. Any other structural BMPs that may require
maintenance, such as secondary containment around fuel tanks or the conditions of
spill response kits shall also be inspected. Stormwater items to be inspected include
the following:
Condition & failures of structural & non-structural BMPs
Perimeter and outfall structure
Evidence of spills, upsets & discharges
Maintaining accurate SWMP report documentation
Material handling and storage
Good housekeeping
Site stabilization
Meet authorities during inspections
Update permit disturbed acreage
Equipment and vehicle storage area
Maintenance records of equipment, systems & operations
The project site and the adjacent streets and parking areas impacted by the
construction shall be kept neat, clean and free of debris. The control measures and
facilities need to be maintained in good working order. Any items that are not
functioning properly or are inadequate should be promptly repaired or upgraded. The
site shall be inspected by responsible personnel who are familiar with the site.
Inspection and monitoring will follow the procedures outlined below:
Minimum Monitoring (Inspection) Requirements:
Inspections of the construction site shall be conducted by the contractor (or
agent) every two weeks and after significant storm events.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
The qualified site superintendent familiar with this SWMP report/BMP shall
perform the inspections.
The contractor shall certify the site is in compliance with the SWMP
report/BMP and the permit by:
o Ensuring that areas contributing significant storm water discharges
related to the construction activities have been identified.
o Evaluating preventive measures required by the SWMP report /BMP to
insure they are adequate and has been properly implemented.
o Points of discharge from the site will be inspected to check for signs of
pollutant discharge.
o Certifying the grade, elevations, and capacity of permanent
sedimentation facilities.
o Determining if additional control measures will need to be
implemented.
o Updating this SWMP report if new measures are implemented or
existing controls are deleted.
Based on the results of the inspection, the description of potential pollutant sources,
and the pollution prevention and control measures that are identified within this plan
shall be revised and modified as appropriate and as soon as practicable after such
inspection. Typically, corrective action shall commence immediately when a
deficiency is observed.
In addition to the inspections performed at least every 7 days, several daily
inspections will be required. Each day when any type of construction activity has taken
place onsite, qualified personnel provided by the General Contractor shall:
Inspect all onsite areas where petroleum products are stored, used or handled
for spills and leaks from vehicles and equipment.
Inspect all onsite locations where vehicles enter or exit the site for evidence
of offsite sediment tracking.
5.2. Final Stabilization and Long-Term Stormwater Management
Permanent stabilization will be achieved by establishing a vegetative cover on all
disturbed areas. The vegetative cover will be as specified on the Landscape Plan. Final
stabilization shall be considered complete when all paving and landscaping are
completed and the vegetative cover has been established with a density of at least 70
percent of pre-disturbance levels (including shrubs and trees).
Temporary and permanent seeding shall be completed within 14 days after grading
has ceased and left to idle for more than 30 days. Care should be taken to complete
seeding activities prior to November 1st for disturbed land intending to remain
inactive for the winter months.
Pickleball Ventures – Pickleball Facility
Stormwater Management Plan
Roughening and scarifying disturbed areas is allowed as a temporary stabilization
under the following conditions:
During winter activity.
There is intention to seed in the spring/fall seasons.
There is intention for further mitigation methods to be active within 2-3
months of inactivity (with Stormwater approval).
Management of storm water after completion of construction will be accomplished
by utilizing the practices listed below:
Upon completion of construction, the site shall be inspected to ensure that all
equipment, waste materials, and debris have been removed.
The site will be inspected to make certain that all graded surfaces have been
landscaped or seeded with an appropriate ground cover.
Upon acceptance of final stabilization measures, all temporary BMPs shall be
removed and proper function of inlets, drainage ways, or other storm water
conveyance elements shall be restored.
The storm sewer systems and the detention pond will be returned to full
capacity and the outlet structures will be checked to assure they are unclogged
and in working order.
The General Contractor shall remove all temporary erosion and sediment control
BMPs after stabilization is achieved or after temporary BMPs are no longer needed.
Trapped sediment will be removed by the General Contractor or stabilized onsite.
Disturbed soil areas resulting from removal of BMPs or the General Contractor will
permanently stabilize vegetation as soon as possible.
The General Contractor shall be responsible for maintaining the storm water controls
in good working order including removal measures until an Inactivation Notice is filed
with the State. The state requires the Inactivation Notice to be filed within 3 months
of the proposed end of construction. Alternatively, permit responsibilities may be
transferred or reassigned by submitting a Notice of Transfer and Acceptance of Terms
or a Reassignment of Coverage if control of a portion of the site changes parties.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.
