Wattles are tubes of straw, rice straw, or coconut husk encased in ultraviolet (UV) degradable plastic netting or 100% biodegradable burlap material_ Wattles are used to help stabilize steep slopes where silt fence is difficult to install. Installing wattles will help break up the length of the slope which will help reduce the overall velocity of the overland flow. Wattles can also be used as perimeter control devices and ditch checks in areas of low flow. Refer to SUDAS Figure 9040.5 on the following page and Section 7.3 of this report for locations, installation and specification requirements. The engineer reserves the right to adjust locations and add additional protection areas as conditions warrant. 60312360/400/S Hills Drainage SWPPP-TDCdocx 11 December 2013 i AO 1133HS I 5.0406 3an!id I e o3 jcn gs eery pegjn;sia 0) 74- CD a1 ol 83; TI /0, 3 a a m b° 0 — m 0' a m suoRecgoeds pepue;s svans om — N �O vCD 53 �m am mg Lo_3 co 0 m c A- 1 a = �0. m0 — a AXOM Storm Water Pollution Prevention Plan (SWPPP) South Hills Drainage Improvements Waterloo, Iowa 5.3 DUST CONTROL This project is located in an urban area, and dust control will be required during the construction process. Dust control is the practice of controlling fugitive dust that results from grading, demolition, hauling and traffic on construction sites. Fugitive dust may cause off-site damage, health hazards, and traffic problems if preventative measures are not taken. Various methods of dust control may be employed during construction and should be approved by the engineer prior to application. Possible dust control methods include watering, surface roughening, and dust suppressants such as Calcium Chloride and soybean oil. The contractor is responsible for implementing dust control during the construction process. 5.4 CONCRETE WASHOUT AREA(S) Concrete washout area(s) are required during all paving operations. Washout area(s) shall be set up on-site and clearly marked during all paving operations. The washout area must be accessible to concrete trucks during wet or muddy conditions and must have adequate storage volume to contain all concrete washout. The contractor shall determine the location of the washout prior to any paving operations and update the SWPPP as necessary to show this location. 5.5 SANITARY/TRASH CONTROL A porta-potty shall be placed on-site in an area that would minimize pollution through storm water runoff if a spill were to occur. This location will vary depending on construction staging. The location shall be added to the Pollution Prevention Plan sheets. Dumpsters and hazardous material/chemical storage areas shall also be set up and clearly marked on-site and on the Pollution Prevention Plan sheets. These locations may also vary depending on the construction staging. The contractor is responsible for providing knowledge of spill prevention and clean-up to all employees working on-site. 5.6 CONTRACTOR OPERATIONS All contractors shall conduct their operations in a manner that controls pollutants, minimizes erosion, and prevents sediments from entering waters of the state. The prime contractor shall be responsible for compliance and implementation of the Pollution Prevention Plan for their entire contract. This responsibility shall be further shared with subcontractors whose work is a source of potential pollution. NPDES certification statements shall be signed and submitted to the SWPPP inspector prior to the beginning of construction by all contractors and subcontractors for the project. Refer to Chapter 4 for the certification forms. The prime contractor shall determine employee parking and storage areas prior to construction and present this information to the project engineer for approval. This information shall also be added to the Pollution Prevention Plan sheets. 60312360/400/S Mils Drainage SWPPP-TDCdocx 12 December 2013 1 OM Storm Water Pollution Prevention Plan (SWPPP) South Hills Drainage Improvements Waterloo, Iowa CHAPTER 6 SITE INFORMATION 6.1 GENERAL SITE LOCATION 60312360/400/S HBis Drainage SWPPP-TDCdocc 13 December2013 w F- z a� D ZIPMMINIMIENtekhaltaistA EN WI" 40 MEM IIIMMEMINIMINNIENNIIIII: NO Ihi4111110111 111 111111 ommuliniss 111 mmtc simmillsou _mu au 0\ Lam_. umMUT,11 Imm>•m igimm NMI SCALE IN MILES 1 2 3 4 0 8.000 SCALE IN FEET 16.000 Ci of Waterloo Black Hawk County, Iowa LiElpura i1i1f7f%1f sli!

The corresponding range, township, section and quarter section are as follows: R13W, T89N, Section 14, NE % and NW %. The current ground cover for the project location is existing turf grass. The current grade is relatively flat, with slopes ranging from 0.5% to 1.0%. The golf course will not be open during construction. The current drainage system consists of small diameter drain tiles and overland flow that tie into a tributary of Sink Creek. The overland flow path crosses the 14th and 15th fairways, which can cause partial closures during and after moderate to heavy rains. This project will improve the drainage during these storm events by incorporating an underground storm sewer pipe that will convey water more efficiently to the existing outlet point. During construction and until vegetation is established, all areas shall be protected from erosion and sediment accumulation. The primary soil unit located at the project site is Kenyon -Floyd -Clyde according to the Iowa DOT soil mapping. This is classified as a moderate to well -drained soil type, with a hydraulic soil group classification of B. The existing runoff curve number of 61 will remain the same after project completion. The majority of soil disturbing activity will be from the trenching required to install the underground storm sewer piping. During this phase, the contractor shall utilize the construction entrance/exit as shown in the plans. Sweet Water Circle shall be kept clean from vehicle tracking. Any tracking that does occur shall be cleaned up within 24 hours of occurrence. Refer to Section 7.3 for the overall Storm Water Pollution Prevention Plan layout for erosion and sediment control for this project site. Wattles and existing vegetation will be the main Pollution Prevention Plan controls during construction. Before construction is to begin, the City Engineer shall be contacted for a pre -construction inspection. Upon approval from the City Engineer, ground -disturbing activities may begin. During grading activities, additional pollution prevention measures shall be added as conditions warrant. During construction, the contractor shall maintain all storm water pollution prevention controls discussed in Chapter 5 and report any deficiencies found. The contractor shall not disturb desirable grass areas or desirable trees outside the construction limits during construction. During paving operations, the contractor shall set up and use a concrete washout area. The total construction site area is approximately 1.1 acres, with an estimated 1.1 acres being disturbed. Runoff from this project will flow into a tributary to Sink Creek and ultimately to the Cedar River. Refer to the project plans for locations of typical slopes, ditch grades, and major structural and non-structural controls. 60312360/400/S Hills Drainage SWPFP-TDC docs 14 December 2013 Storm Water Pollution Prevention Plan (SWPPP) South Hills Drainage Improvements Waterloo, Iowa CHAPTER 7 POLLUTION PREVENTION PLAN LAYOUT AND DESIGN 7.1 SEQUENCE OF POLLUTION PREVENTION ACTIVITYIGENERAL NOTES A.

KEEPING PLANS CURRENT The permittee shall amend the plan whenever there is a change in design, construction, operation, or maintenance, which has a significant effect on the potential for the discharge of pollutants to the waters of the United States and which has not been addressed in the plan or if the storm water pollution prevention plan proves to be ineffective in eliminating or significantly minimizing pollutants from sources identified in Part IV.D.2. of this permit, or in otherwise achieving the general objectives of controlling pollutants in storm water discharge associated IOWA DEPARTMENT OF NATURAL RESOURCES NPDES GENERAL PERMIT No. 2 STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL ACTIVITY FOR CONSTRUCTION ACTIVITIES EFFECTIVE DATE - OCTOBER 1, 2012 TO OCTOBER 1, 2017 with industrial activity for construction activities. In addition, the pollution prevention plan shall be updated to: expeditiously change the site map to include changes at the site, include contractors identified after the submittal of the Notice of Intent as Co -permittees, described in Part IV.D.7. of this permit; identify any change in ownership or transference of the permit and permit responsibilities; or, if required, by the occurrence of a hazardous condition (as defined in Part VIII of this permit). Amendments to the plan may be reviewed by the Department of Natural Resources in the same manner as Part IV.B.2. D. CONTENTS OF THE POLLUTION PREVENTION PLAN. The storm water pollution prevention plan shall include the following items: 1. SITE DESCRIPTION Each plan shall provide a description of the following: A. a description of the nature of the construction activity; B. estimates of the total area of the site and the area of the site that is expected to be disturbed by excavation, grading, or other activities; C. an estimate of the runoff coefficient of the site after construction activities are completed and existing data describing the soil or the quality of any discharge from the site; D. a site map indicating drainage patterns and approximate slopes anticipated after major grading activities, areas of soil disturbance, the location of structural and nonstructural controls identified in the plan, the location of areas where stabilization practices are expected to occur, surface waters (including wetlands), and locations where storm water is discharged to a surface water; and E. the name of the receiving water(s) and the ultimate receiving water(s). 6 2. CONTROLS Each plan shall include a description of controls that will be implemented at the construction site. The plan will clearly describe the intended sequence of major activities and for each activity, the appropriate control measures and the timing during the construction process that the measures will be implemented. (For example, perimeter controls for one portion of the site will be installed after the clearing and grubbing necessary for installation of the measure, but before the clearing and grubbing for the remaining portions of the site. Perimeter controls will be actively maintained until final stabilization of those portions of the site upward of the perimeter control. Temporary perimeter controls will be removed after final stabilization). The description of controls shall address the following minimum components: A. EROSION AND SEDIMENT CONTROLS A.(1). STABILIZATION PRACTICES A description of temporary and permanent stabilization practices, including site-specific scheduling of the implementation of the practices. Site plans should ensure that existing vegetation is preserved where attainable and that disturbed areas are stabilized. Stabilization practices may include: temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, preservation of mature vegetation, and other appropriate measures. Except as precluded by snow cover, stabilization measures shall be initiated on all disturbed areas as soon as practical but in no case where construction activity will not occur for a period of 21 or more calendar days later than the 14th day after no construction activity has occurred on such area. Where the initiation of stabilization measures by the 14th day after no construction activity occurs is precluded by snow cover, then stabilization measures shall be initiated as soon as practicable thereafter. A.(2). STRUCTURAL PRACTICES A description of structural practices to the degree attainable, to divert flows from IOWA DEPARTMENT OF NATURAL RESOURCES NPDES GENERAL PERMrr No. 2 STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL. ACTIVITY FOR CONSTRUCTION ACTIVITIES EFFECTIVE DATE - OCTOBER 1, 2012 TO OCTOBER 1, 2017 exposed soils, store flows or otherwise limit runoff from exposed areas of the site. Such practices may include silt fences, earth dikes, brush barriers, drainage swales, sediment traps, check dams, subsurface drains, pipe slope drains, level spreaders, storm drain inlet protection, rock outlet protection, reinforced soil retaining systems, gabions, and temporary or permanent sediment basins. Structural practices should be placed on upland soils to the degree attainable. The installation of these devices may be subject to Section 404 of the CWA. A.(2).(a). For common drainage locations that serve an area with more than 10 disturbed acres at one time, a temporary or permanent sediment basin providing 3,600 cubic feet of storage per acre drained shall be provided where attainable until final stabilization of the site has been achieved. The 3,600 cubic feet of storage area per acre drained does not apply to flows from offsite areas and flows from onsite areas that are either undisturbed or have undergone final stabilization where such flows are diverted around the sediment basin. For drainage locations which serve more than 10 disturbed acres at one time and where a temporary sediment basin providing 3,600 cubic feet of storage per acre drained is not attainable, sediment traps, silt fences, or equivalent sediment controls are required for all sideslope and downslope boundaries of the construction area. A.(2).(b). For drainage locations serving 10 or fewer acres, sediment traps, silt fences or equivalent sediment controls are required for all sideslope and downslope boundaries of the construction area or a sediment basin providing for 3,600 cubic feet of storage per acre drained. A.(2).(c). Unless infeasible, the following measures shall be implemented at all sites: utilize outlet structures that withdraw water from the surface when discharging from basins, provide and maintain natural buffers around surface waters, direct storm water to vegetated areas to increase sediment removal and maximize storm water infiltration and minimi soil compaction. Topsoil shall be 7 preserved at all construction sites unless land use precludes the practice. The requirement to preserve topsoil shall be met only when the depth of topsoil after soil disturbing activities have been completed and final stabilization achieved for the permitted activity is equal to, or greater than, 4.0 inches, including soil contained in sod, on all areas of the site where the surface of the ground disturbed for the permitted construction activities is exposed and not covered by concrete, asphalt, gravel or other such material and where 4.0 inches or more of topsoil existed prior to the commencement of soil disturbing activities that are permitted under the current permit authorization for the site. On areas where less than 4.0 inches of topsoil existed prior to the commencement of soil disturbing activities that are permitted under the current permit authorization for the site, the minimum depth of topsoil after soil disturbing activities have been completed and final stabilization achieved for the permitted activity shall be equal to, or greater than, the depth of topsoil that existed prior to the commencement of soil disturbing activities that are permitted under the current permit authorization for the site. The final topsoil depth is to be measured after the soil has been compacted in a fashion generally considered adequate for an established lawn and so that the expected settling that will occur after measurement will be minimal and shall include the soil contained in any sod that has been placed on the site. The type of topsoil at the site after soil disturbing activities have been completed and final stabilization achieved for the permitted activity shall be similar to that which exists or existed in the general area of the site. For construction activity which is part of a larger common plan of development, such as a housing or commercial development project, in which a new owner agrees in writing to be solely responsible for compliance with the provisions of this permit for the property which has been transferred or in which the new owner has obtained authorization under this permit for a lot or lots (as specified in subrule 567-64.6(6) of the Iowa Administrative Code), the topsoil preservation IOWA DEPARTMENT OF NATURAL RESOURCES NPDES GENERAL PERMIT No. 2 STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL ACTIVITY FOR CONSTRUCTION ACTIVITIES EFFECTIVE DATE - OCTOBER 1, 2012 TO OCTOBER 1, 2017 requirements described above must be met no later than at the time the lot or lots have reached final stabilization as described in this permit. For sites where less than 4.0 inches of topsoil is to be in place after soil disturbing activities have been completed and final stabilization achieved for the permitted activity, a soil survey conducted by properly qualified personnel who regularly conduct soil surveys as part of their normal job duties must be conducted prior to commencement of soil disturbing activities that are permitted under the current permit authorization for the site. The results of the soil survey shall become part of the Pollution Prevention Plan and shall indicate the depth of topsoil at a suitable number of points on the site commensurate with standard engineering practices established for the size of the site. The topsoil preservation requirement described above shall be implemented for projects that have not received an authorization under this permit prior to October 1, 2012. The topsoil preservation requirements are not required to be implemented for projects that have been authorized prior to October 1, 2012. In residential and commercial developments, a plat is considered a project. For other large areas that have been authorized for multiple construction sites, including those to be started at a future date, such as those located at industrial facilities, military installations and universities, a new construction project not yet surveyed and platted out is considered a project. This stipulation is intended to be interpreted as requiring the topsoil preservation requirements on development plats and construction activities on other extended areas that may have several construction projects permitted under the same authorization to be implemented on those projects not yet surveyed and platted out prior to October 1, 2012 even if other plats and construction activities in the same development or other extended area were authorized prior to October 1, 2012. B. STORM WATER MANAGEMENT A description of measures that will be installed during construction to control pollutants in 8 storm water discharges that will occur after construction operations have been completed. The installation of these devices may be subject to Section 404 of the CWA. This permit only addresses the installation of storm water management measures, and not the ultimate operation and maintenance of such structures after the construction activities have been completed and the site has undergone final stabilization. Permittees are only responsible for the installation and maintenance of storm water management measures prior to final stabilization of the site, and are not responsible for maintenance after storm water discharges associated with industrial activity have been eliminated from the site. B.(1). Such practices may include: storm water detention structures (including wet ponds); storm water retention structures; flow attenuation by use of open vegetated swales and natural depressions; and infiltration of runoff onsite; and sequential systems (which combine several practices). A goal of 80 percent removal of total suspended solids from those flows which exceed predevelopment levels should be used in designing and installing storm water management controls (where practicable). Where this goal is not met, the permittee shall provide justification for rejecting each practice based on site conditions. B.(2). Velocity dissipation devices shall be placed at discharge locations and along the length of any outfall channel as necessary to provide a non-erosive velocity flow from the structure to a water course so that the natural physical and biological characteristics and functions are maintained and protected (e.g. maintenance of hydrologic conditions present prior to the initiation of construction activities). C. OTHER CONTROLS C.(1). WASTE DISPOSAL All wastes composed of building materials must be removed from the site for disposal in permitted disposal facilities. No building material wastes or unused building materials S. IOWA DEPARTMENT OF NATURAL RESOURCES NPDES GENERAL PERMIT No. 2 STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL ACTIVITY FOR CONSTRUCTION ACTIVITIES EFFECTIVE DATE - OCTOBER 1, 2012 TO OCTOBER 1, 2017 shall be buried, dumped, or discharged at the site. c.(2). Off-site vehicle tracking of sediments shall be minimized. c.(3). The plan shall ensure and demonstrate compliance with applicable State or local waste disposal, sanitary sewer or septic system regulations. D. APPROVED STATE OR LOCAL PLANS Facilities which discharge storm water associated with industrial activity for construction activities must include in their storm water pollution prevention plan procedures and requirements specified in applicable sediment and erosion site plans or storm water management plans approved by State or local officials. Applicable requirements specified in sediment and erosion plans, site permits or storm water management plans approved by State or local officials that are applicable to protecting surface water resources are, upon submittal of an NOI to be authorized to discharge under this permit, incorporated by reference and are enforceable under this permit even if they are not specifically included in a storm water pollution prevention plan required under this permit. Operators of facilities seeking alternative permit requirements shall submit an individual permit application in accordance with Part I.C.2. of this permit along with a description of why requirements in approved State or local plans should not be applicable as a condition of an NPDES permit. 3. MAINTENANCE A description of procedures to maintain in good and effective operating conditions vegetation, erosion and sediment control measures and other protective measures identified in the site plan. 4. INSPECTIONS Qualified personnel (provided by the discharger) shall inspect disturbed areas of the construction site that have not been stabilized with a perennial, vegetative cover of sufficient density to preclude erosion at least once every seven calendar days. Unless erosion is evident or other conditions 9 warrant them, regular inspections are not required on areas that have been stabilized with a perennial, vegetative cover of sufficient density to preclude erosion. A. Disturbed areas and areas used for storage of materials that are exposed to precipitation shall be inspected for evidence of, or the potential for, pollutants entering the drainage system. Erosion and sediment control measures identified in the plan shall be observed to ensure that they are operating correctly. Where discharge locations or points are accessible, they shall be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to receiving waters. Locations where vehicles enter or exit the site shall be inspected for evidence of offsite sediment tracking. B. Based on the results of the inspection, the description of potential pollutant sources identified in the plan in accordance with paragraph IV.D.1. of this permit and pollution prevention measures identified in the plan in accordance with paragraph IV.D.2. of this permit shall be revised as appropriate as soon as practicable after such inspection. Such modifications shall provide for implementation of any changes to the plan within 7 calendar days following the inspection. C. A report summarizing the scope of the inspection, name(s) and qualifications of personnel making the inspection, the date(s) of the inspection, major observations relating to the implementation of the storm water pollution prevention plan, and actions taken in accordance with paragraph IV.D.4.B. of the permit shall be made and retained as part of the storm water pollution prevention plan for at least three years after final stabilization has been achieved and a Notice of Discontinuation has been submitted to the Department. The report shall be signed in accordance with Part VI.G. of this permit. 5.
