Round Lake Area Park District, ILLakewood Grove Community Park

001511-08113-0

1. Site DescriptionThe Round Lake Area Park District plans to develop the Lakewood Grove Community Park site with the purpose ofcreating new recreational opportunities. The approximately 12.8-acre site is located north of Illinois Route 60 andArden Lane in the Village of Round Lake. The project site is situated in northeast ¼ of Section 8, Township 44North, Range 10 East in the Fremont Township, Lake County, Illinois. The project involves the construction of soccerfield access, playground area, recreational trials, picnic shelter, parking facility, and entrance drive.

The intended sequence of major activities which disturb soils:Install perimeter silt fence, construction entrance, construction entrance.Permanent erosion control structures will be installed when appropriate during the construction process.Tree and brush clearing.Strip and stockpile topsoil.Complete necessary grading.Construction of shelter, drives, and parking.Respread topsoil on completed sections and vegetate.Restore remaining disturbed areas.

Construction activities will begin April 2009 and the completion date is August 2009.

Total estimated area of the site is 12.8 acres.

Soils on the project site consist of Ashkum silty clay loam and Martinton silt loam (Hydrologic Group C).

Existing Runoff Coefficient: CN = 80Proposed Runoff Coefficient: CN = 85

The project site is in the Fox River watershed with the overall prevailing drainage pattern from the southeast tonorthwest. The site drains to wetlands, which drains into Squaw Creek, Long Lake, Fox Lake, Nippersink LakePistakee Lake, and into the Fox River. Upland open space, wetlands, and the Squaw Creek are found within theproject area.

2. Potential Discharge of Sediment and/or Other Potential PollutantsSummary of Areas of ConcernThe following items have been considered areas of concern for this project:

1. Sediment tracking on adjacent streets.2. Wind/Dust erosion.

All areas outside of the construction limits of this project will remain undisturbed throughout the duration of theconstruction process.


Control Measures for Areas of ConcernThe following control measures address the critical issues listed above.

1. A rock construction entrance will be utilized to access the site and prevent sediment tracking onto adjacentstreets.

2. Adjacent streets will be swept as needed.3. Straw, mulch, or water, or in combination, will be applied to dry soils as needed to reduce the amount of

wind/dust erosion.

Summary of Critical IssuesThe following items have been considered areas of concern for this project:

1. Sediment entering wetlands.2. Sediment entering Squaw Creek.

All areas outside of the construction limits of this project will remain undisturbed throughout the duration of theconstruction process.

Control Measures for Critical IssuesThe following control measures address the critical issues listed above.

1. All open soil not actively being worked after 14 days will be temporarily seeded and mulched to preventsediment laden runoff to critical areas.

2. Silt fence will be installed on all down gradient perimeters to limit the amount of sediment leaving the siteand entering wetlands and Squaw Creek.

3. All exposed stockpiles will be enclosed with silt fence and temporary cover will be applied if not activelyworked after 7 days.

4. A stabilized construction entrance will be utilized to access the site and prevent sediment tracking ontoadjacent streets which drain to Squaw Creek.

5. Adjacent streets will be swept as needed.6. A perforated riser will be installed at the detention basin outlet.7. Erosion control blanket and turf reinforcement mat will be installed on all newly graded slopes.

Other Potential PollutantsThe table below represents possible storm water pollutants, and control measures for each, which will be presentduring the construction of this project:

Potential Pollutant Location Control MeasureAntifreeze Random leaks Trained personnelDiesel Fuel Secondary containment Oil absorbing diapers, trained

personnelFertilizer Areas to be sodded Managed application, certified

installers, not stored on-siteGasoline Secondary containment Oil absorbing diapers, trained

personnelHydraulic oil/fluids Random leaks Properly stored, oil absorbing

diapers, trained personnelGlue/Adhesives Pipe joints Empty container management

Hydraulic oil/ fluids Random leaks Oil absorbing diapers, trainedpersonnel


Stabilization PracticesTemporary soil stabilization shall be applied to disturbed areas within 14 days of the end of active hydrologicdisturbance. Soil can be temporarily stabilized using spring oats, wheat or cereal rye, straw or hydro mulch.Permanent stabilization (native vegetation or sod) shall be done within 7 days after completion of final grading ofthe soil.

Structural PracticesStructural practices to be installed include silt fence, stabilized construction entrance, erosion control blanket, turfreinforcement mat, and perforated riser. Structural measures will limit runoff and the discharge of pollutants fromleaving the site. The perforated riser will be installed at the detention basin outlet.

Storm Water ManagementDue to the nature of the project, recreational development project with shelter and on-site surface parking, thecreation of impervious surfaces is inherent in the design. Attempts have been made to minimize the percent of newimpervious surfaces. The total proposed impervious acreage is 1.28 out of 12.79 acres or about 10% of the totaldevelopment acreage.

The project site is surrounded by public right-of-way, residential lots, wetlands, and the Squaw Creek. No wetlandimpacts are anticipated.

Best Management Practices (BMPs) will be employed to prevent water quality impacts. Stormwater runoff willcollect in two inter-connected detention facilities with adjacent vegetated swales to promote infiltration. In largestorm events, excess water that does not infiltrate will discharge to Squaw Creek. The establishment of nativevegetation in the detention basins and vegetated swales will increase water quality by filtering pollutants, excessnutrients, and suspended solids and will slow water velocity, therefore reducing soil erosion.

Waste DisposalSolid waste must be disposed of properly off site by the contractor.

Hazardous materials must be properly stored to prevent spills, leaks, or other discharge. Restricted access to storageareas must be provided to prevent vandalism. Storage and disposal of hazardous waste must be in compliance withcurrent environmental regulations.

External washing of trucks and other construction vehicles are limited to a defined wash-out area. Runoff must becontained and waste properly disposed of. No engine degreasing is allowed on site.

SWPPP ImplementationEach Operator of the site and the area of the site over which the Operator has control are provided in the SWPPP.

Chain of ResponsibilityConstruction Site Superintendent – It is the responsibility of the construction site superintendent to review andapprove the inspector’s corrective action notices and to oversee all areas of the construction project including theinstallation of BMPs.ESC Subcontractor – It is the responsibility of the ESC subcontractor to install and maintain the BMPs recommendedby inspectors and approved by the Construction Site Superintendent.Inspector – It is the responsibility of the inspectors to perform weekly site inspections and to recommend correctiveactions to be completed on site.Trade Partners – It is the responsibility of the trade partners to comply with al parts of this SWPPP.

Installation and Timing of BMPsThe sequence and timing of significant soil-disturbing activities at the site are:

1. Install perimeter silt fence, construction fence, and construction entrance prior to soil disturbance.2. Permanent erosion control structures will be installed when appropriate during the construction process.3. Tree and brush clearing.4. Strip and stockpile soil.5. Install detention basin and perforated riser.6. Compete necessary grading.7. Construction of shelter, drives, and parking.8. Respread topsoil on completed sections and vegetate.9. Restore remaining disturbed areas.

Plan AmendmentsThe Storm Water Pollution Prevention Plan (SWPPP) will be amended if there is a change in design, construction,operation, maintenance, weather or seasonal conditions that has a significant impact on the discharge to surfacewaters or underground waters. The Plan will also be amended if it is proven to be inadequate in controllingpollutants in storm water discharges due to construction activities.

Final Stabilization MethodsFinal site stabilization is achieved when perennial vegetative cover provides permanent stabilization with a densitygreater than 70 percent over the entire pervious surface area, or other equivalent means necessary to prevent soilfailure under erosive conditions.

All temporary synthetic and structural erosion prevention and sediment control BMPs must be removed as part of thefinal stabilization. Accumulated sediment must be cleaned out from sediment basin.

3. MaintenanceDuring construction activity, the maintenance of all BMPs will be required as set forth in the SWPPP.

4. InspectionsThe ESC Technician will inspect the site on a weekly basis and within 24 hours of every 0.5-inch storm event. An“Incidence of Noncompliance” report should be completed for any SWPPP violations and submitted the EnforcementOfficer.


5. CalculationsHydrologic and Hydraulic AnalysisThe hydraulic analysis and modeling for the storm sewer system was performed using HydroCAD with Bulletin 70rainfall amounts and appropriate Huff distributions. Assumptions and the methodology used in developing themodels of the pipe networks are as follows:

Times of concentration were calculated using the TR-55 tabular method.Tributary drainage areas, composite curve numbers and land/watercourse slopes were computed from thetributary drainage areas.The 2-year 24-hour rainfall of 2.80 inches is taken from Bulletin 70 for Lake County, Illinois.CN of 80 applies to the pervious areas of the site. Impervious areas have a CN of 98.0.676 acre-feet of on-site stormwater detention is provided.

Inspection Log Guidance

General

Provisions of the NPDES Permit require that weekly and event driven inspections be done for all permittedprojects. A log of these inspections, and resulting corrective actions (maintenance), is also required.Therefore, the ESC Inspection Log is set up from the perspective of the permit requirements.

It is a good idea to take photos during inspections to photo-document good practices and site conditions aswell as BMPs or site conditions in need of corrective action. Then take photos during the followinginspection to document that the corrective action(s) has been done (or not).

Following is a description and explanation (where necessary) of all headings on the Inspection Log.

Project Name: Include Phase, Addition or other distinctions included on permit/application

Owner: The City or private client that the permit was obtained for

Contractor: Typically the prime or primary contractor signed on the Permit. May change with phase ofproject.

NPDES Permit #: Shown as the “Identification Number” on the yellow permit card (Notice of Storm WaterPermit Coverage)

Owner Project #/Bonestroo Project #: Self explanatory

Bonestroo Inspector: Our inspector doing the ESC inspection on our permitted portion of the project site.Could be from Construction Services or from the ESC Team.

ESC Supervisor: The individual named by and working for the contractor that is the go-to person for ESCissues.

ESC Contractor: The company subbed by the contractor to install, maintain, etc all ESC BMPs.

Date of Inspection: Must be no more than a week since the last date of inspection.

Type of Inspection: Is it the weekly inspection or within 24-hours of a rain event of more than ½ inch of rain.

Date of Last Rain: Any amount of rain. There should be a rain gauge on site. This is important because ifwe got only 3/10 inch, an event inspection is not required. Repeat last rain date on weekly during dry periods.

Amount of Rain: If this is ½ inch or more, the date of inspection should be no later than the next day.

Runoff Controlled?/Erosion Minimized?/Sediment Managed?: In keeping with objectives of constructionsite ESC, evaluate the site overall in these terms. Use this as an indicator for which BMPs are working, or not.

Corrective Action Required: Pertains to particular BMPs, practices, site conditions, etc.

Prior Corrective Action Completed?: Did the contractor satisfactorily complete the activities required asthe result of the last inspection or Corrective Action Notice?

Comments: Photos taken? Change of contractor/ESC tech? Large/intense rain? Corrective action issues? Etc.

Location of Permit Posting: Where the permit card is posted on the project site (required).
