14 IIW, P.C Pennsylvania Avenue Dubuque, IA (563) (563) (Fax) IIW, P.C. has been asked to complete an application for the City of Calamus for the Iowa Department of Natural Resources (IDNR) Clean Water State Revolving Fund (CWSRF) Water Resource Restoration Sponsored Projects. The City of Calamus and IIW have received assistance during the application process from Amy Bouska from the Iowa Department of Agriculture and Land Stewardship. The following information below addresses and answers the requirements identified in the Application Completeness Checklist. Assessment of the impacted waterbody and its watershed with data that supports the identification of the water quality problems to be addressed The City of Calamus is located near a local high spot of the regional topography. Hence, the City takes relatively little runoff from the areas surrounding the City s corporate limits. The receiving streams for the City of Calamus possible water resource restoration projects are an unnamed tributary of the Wapsipinicon River and an unnamed tributary of Calamus Creek in Clinton County. The unnamed tributary to the Wapsipinicon River appears to be a man-made channel to provide drainage of fields. Calamus Creek is also a tributary of the Wapsipinicon River. Calamus Creek has the following designated use classes: Class A1 and Class B (WW-2). The current designated use of Calamus Creek is aquatic life. The Wapsipinicon River has been included on Iowa s 303(d) list of impaired waters. The identified impaired use for the Wapsipinicon River is primary contact with the cause/stressor for the river being indicator bacteria. The current designated use classes for the Wapsipinicon River are Class A1, Class B (WW-1), and Class HH. The current designated uses for the Wapsipinicon River are Aquatic Life, Fish Consumption, and Primary Contact (Recreation). The listing rationale for the river is greater than 10% of samples containing greater than 400 orgs/100 ml. The possible proposed projects that would be implemented would capture runoff and promote infiltration and allow the water to flow through an engineered soil. These improvements will not only lower the amount of runoff generated by the City of Calamus but will also reduce the amount of nutrients and suspended solids released to the Wapsipinicon River. Exhibit A - EX A has been included in the application which portrays the two watershed areas associated with the City of Calamus. Generally, the Union Pacific Railroad that runs through the City of Calamus acts as the delineation line between the two watershed areas within the City. The northerly portion of town drains away from the railroad to the north to an unnamed tributary of Calamus Creek. The southerly portion of town drains to an unnamed tributary of the Wapsipinicon River. Exhibit B - EX B delineates the individual drainage areas within the City of Calamus. 1 P age

15 Discussion of project goals and objectives The measures that are identified in this application will provide improvement to stormwater quality through reductions in total suspended solids and nutrients. With the implementation of some best management practices (BMPs) the water can be captured in areas where infiltration will be promoted. With the capture and infiltration of runoff, the amount of nutrients and suspended solids will be lessened due to the capture of the runoff in these BMP areas. The City hopes to utilize BMPs such as bio-swales, bio-retention cells, and rain gardens to promote infiltration and removal of nutrients and suspended solids. The main objectives for the CWSRF Water Resource Restoration Sponsored Project with respect to the City are as follows: 1. Improve the water quality of the watersheds influenced by the City of Calamus. 2. Establish a working relationship with the local District and Watershed Conservationists and the Iowa Department of Agriculture and Land Stewardship representatives, so future BMPs might be incorporated in future public improvement projects within the City of Calamus. With the implementation of the identified BMP measures the City hopes to achieve secondary benefits of addressing runoff and drainage problems throughout the City. The City s existing storm sewer system is undersized in many areas throughout town. The undersized inlets and pipes lead to localized flooding and ponding in undesirable areas and have even resulted in water intrusion into buildings and basements. The implementation of these BMPSs could help to decrease nuisance ponding by keeping it contained within the BMP area. These BMP measures should also help to decrease the detrimental effects of the City s undersized storm sewer by lessening the peak runoff generated by the particular watershed. These goals and objectives would be considered a secondary benefit with the improvement of water quality throughout the various watersheds being the primary goal and objective of the project. Evaluation of possible water quality practices that could be implemented, considering the unique demographic, topographic, hydrologic, and institutional characteristics of the planning area The City of Calamus existing roadway type and storm sewer system consists of mainly rural section with very little curb and gutter present. The roadways primarily consist of ditches behind the edge of the roadway with small culverts, inlets, and storm sewer piping to convey the water to either the north or the south side of town. The proposed water quality improvement projects could be implemented in the public right-of-way; property acquisition will not be required for the proposed projects. The proposed improvements for the projects include rain gardens, bio-swales and bio-retention cells. These types of improvements would work best for the community with the improvements being implemented in the limited amount of area that is within the public right-of-way. The City of Calamus has an overall topography of low to moderate slopes with elevations throughout town ranging from approximately 680 feet (MSL) to 700 feet (MSL). Generally the slopes of the existing topography are minimal which are beneficial for the implementation of water quality measures that promote infiltration with a minimal amount of grading. The City is planning on utilizing bio-retention type BMPs as one of the options as described above. Bio-retention areas are described in the Iowa Stormwater Management Manual as follows: Bio-retention areas are shallow stormwater basins or landscaped areas that utilize engineered soils and vegetation to capture and treat 2 P age

16 stormwater runoff. Runoff may be returned to the conveyance system, or allowed to partially or fully infiltrate into the soil. There are two different types of bio-retention that are identified in the Stormwater Management Manual: bio-retention areas and rain gardens. The City will utilize more bio-retention areas than rain gardens. The design and construction of the bio-retention BMP areas will implemented in accordance with the Iowa Stormwater Management Manual. The other BMP option that the City could utilize with the Sponsored Project is Bioswales. Bioswales are described in the Iowa Stormwater Management Manual as follows: Bioswales are vegetated open channels that are explicitly designed and constructed to capture and treat stormwater runoff within dry or wet cells formed by check dams or other means. With the City s existing roadway type (mainly rural with open ditches), the bioswales can be utilized by modifying the existing roadway ditches. The design and construction of the bioswales will be implemented in accordance with the Iowa Stormwater Management Manual. Description of potential practices to be implemented with the expected water quality outcomes The proposed best storm water practices to be implemented as a part of this project are bio-swales, bio-retention cells and rain gardens. The practices will be implemented and designed in accordance with the Iowa Stormwater Manual and be sized appropriately to the size of the tributary area. The practices are planned to be implemented in locations were the existing storm sewer system and drainage patterns cause ponding and backing up of the storm sewer into unfavorable locations. These practices will be implemented to promote the infiltration of the stormwater and allow the sediment and nutrients to settle out of the storm runoff rather than be conveyed downstream. In some cases, these practices may also be capable of capturing a portion of the runoff and reducing the peak flow of that drainage area. The proposed practices that are to be implemented will promote infiltration of the captured water. The selected BMPs are intended to improve water quality by promoting infiltration and providing filtration of suspended solids and nutrients. The proposed BMPs to be implemented as a part of the project have the capability of the removal of the following, according to the Iowa Stormwater Management Manual: total suspended solids, Total Nitrogen, Total Phosphorous and metals. Typical pollutant removal of pollutants from bio-retention areas are as follows: 80% of total suspended solids, 60% of Total Nitrogen, 50% of Total Phosphorous and 50% of metals. Typical pollutant removal of achieved by bioswales are as follows: % of total suspended solids, 30-65% of Total Nitrogen, <30% of Total Phosphorous and % of metals. Typical removal numbers were determined from the Iowa Stormwater Management Manual. Included in the attachments is Table 2 which identifies the volume of treated water and the anticipated various pollutants that the respective BMPs would be able to achieve. The amount of treated water is calculated under the assumption of all the required BMPs to address the total water quality volume that has been calculated for the identified watersheds throughout the City. The pollutant removal percentage is based on the values discussed above which come from the Iowa Stormwater Management Manual. Discussion of project locations, land ownership, and any plans for acquiring properties or easements The City and IIW have identified several areas throughout the City of Calamus where the proposed BMPs can be implemented as a part of the project. The possible locations for the implementation of BMPs are generally located near intakes and culvert inlets of the existing storm sewer system throughout the City. Other locations where BMPs can be implemented are in locations where storm runoff from the nearby agricultural fields enters 3 P age

17 the City s ditches and roadways. There are more potential locations for improvements than funds would allow for. Initial preliminary analysis and a field visit with project stakeholders will be utilized to determine the most impactful and viable locations. All proposed areas are located within the public right-of-way which is owned by the City. It is anticipated that all the proposed improvements would be implemented within the public right-of-way. Acquiring of property or obtaining easements for the identified proposed improvements is not anticipated at this point in time. Identification of any other organizations or resources to be involved in the project and their expected contributions As a part of the application process, design phase and the construction phase of the project, the City and IIW, P.C. will be receiving assistance from the local urban conservationist and soil and water conservation district representative. The City and IIW, P.C. have had both meetings and discussions to discuss the proposed projects and the application for the CWSRF Sponsored Project with the local urban conservationist. The local urban conservationist is Amy Bouska from the Iowa Department of Agriculture Land Stewardship organization. The City and IIW, P.C. have also met the local soil and water conservation district representative to discuss the proposed application and project. The local District Conservationist representative is Bruce Van Laere from the U.S. Department of Agriculture - Natural Resources Conservation Services. Bruce assists the Clinton County Soil and Water Conservation District. The City and IIW, P.C. are planning to utilize both Amy Bouska and Bruce Van Laere as technical resources for both the application as well as the design and implementation of the proposed BMPs for the City of Calamus. Upon grant approval, the City and IIW, P.C. will work with Amy and Bruce to determine the locations of the proposed improvements that will both provide benefit to the City and also have a beneficial impact on the water quality in the watershed. Proposed project schedule with major milestones, along with a discussion of how the sponsored project construction schedule coordinates with the infrastructure project schedule The proposed improvements would be constructed concurrently with the City of Calamus Wastewater Treatment Facility (WWTF) Improvement project. Currently, the City has submitted a Facility Plan to the Iowa DNR for review. The construction of the WWTF improvements are planned to commence sometime in late summer or early fall with construction continuing into the spring and summer of See below for the proposed schedule for the CWSRF Sponsored Project for the City of Calamus.

18 Proposed evaluation procedures and measures There are several goals that the City would like to achieve with the CWSRF Sponsored Project as discussed above. Locations and types of BMPs will be evaluated so that the goals of the City can be met as a part of the project. Asking and answering the following questions helps to identify the evaluation procedures that will be used when determining what BMPs will be installed in specific locations: Has the water quality from the storm runoff been affected positively by the BMPs implementation? Given the size of the overall watershed relative to the mass of the proposed BMPs, a numeric analysis of water quality before and after these improvements would not seem to yield a discernable result. Instead, measurements could be taken at each installed BMP that could provide a reading of the amount of total suspended solids captured by that BMP. We proposed to develop a scheme for such measurements during design and in collaboration with our technical resources. Have the BMPs positively impacted the City and its residents? This question could be answered by a poll of the residents, with field verification during rain events to assess the extent of localized ponding. Upon completion of the proposed BMP improvements the City intends to conduct annual field visits to inspect for maintenance needs, and ensure that the improvements are functioning properly. The City will also perform the necessary maintenance measures associated with the respective BMP. Explanation of the proposed budget, including other planned funding sources and flexibility to adjust budget according to final amount available through the sponsored project mechanism When looking at the possible locations of BMPs to be implemented, an Engineer s Statement of Probable Cost was developed. If BMPs are implemented in every watershed within the City of Calamus as identified in the attached exhibits, the cost could be as much as $1,211, This estimate includes Planning, Engineering, Construction and Construction Observation. See Table 1 attached, which details the average cost for each BMP and the anticipated number that could be implemented within the City of Calamus. The actual eligible costs under the CWSRF program have been tabulated in the application form under Section 6. The City will not be utilizing any other funds for the proposed improvements other than the money that would be generated as a part of the CWSRF Water Resource Restoration Sponsored Project. The extent of the proposed improvements would be selected as to not exceed the amount of money that the City would have with the program. 5 P age
