3 Executive Summary The previous National Pollutant Discharge Elimination System (NPDES) permit for authorization for small Municipal Separate Storm Sewer Systems (MS4s) to discharge storm water (NPDES Permit No. OHQ000002) required the development and implementation of a Storm Water Management Program (SWMP) that satisfied the appropriate water quality requirements of Ohio Revised Code (ORC) 6111 and the Clean Water Act. The SWMP document is intended to identify and describe the best management practices (BMPs) selected by the City of Springdale (City) to meet the requirements of the six minimum control measures (MCMs) described in the permit, why those BMPs were selected in light of local water quality issues, and performance standards for BMP implementation. The six MCMs are: 1. Public Education and Outreach on Storm Water Impacts 2. Public Participation / Involvement 3. Illicit Discharge Detection and Elimination 4. Construction Site Storm Water Runoff Control 5. Post-Construction Storm Water Management in New Development and Redevelopment 6. Pollution Prevention / Good Housekeeping for Municipal Operations The NPDES small MS4 permit was reissued on September 11, 2014 (NPDES Permit No. OHQ000003), and requires MS4 communities which are renewing coverage under this permit to update their SWMP to be consistent with the permit and submit the updated SWMP to Ohio EPA for review. Permit No. OHQ requires that where applicable, BMPs shall be selected to address U.S. EPA approved Total Maximum Daily Load (TMDL) recommendations for identified water quality problems associated with MS4 discharges within the City of Springdale s watershed(s). 3

4 System Overview and Total Maximum Daily Loads (TMDLs) The City of Springdale (City) is located on the northern fringe of Hamilton County in southwestern Ohio. The requirements of the MS4 permit are applicable to the entire City area, which is considered an urbanized area due to the amount of development that has occurred within the City. Based on 2010 census data, the population within the City was 11,223. The land area of the City is 3,209 acres, or approximately 5.01 square miles, highlighted in the figure below. Because of existing topography, the majority of the City flows in an eastern and southern direction and falls within the Mill Creek watershed. A small portion of the City, approximately 50 acres of the Beacon Hills residential development in the northwestern section of the City, flows in a western direction and falls within the Great Miami River watershed. Runoff from both watersheds is ultimately conveyed in a southern direction before discharging into the Ohio River. These two watersheds are highlighted in the following figures. 4

6 Both the Mill Creek watershed and the Great Miami River watershed are in various stages of development through the Ohio EPA s TMDL program. Information on each of the watersheds and current TMDL status is described in the table below. Watershed HUC 10 Mill Creek Status of TMDL Approved in April 2005 Pollutants for TMDL Nutrients, including dissolved nitrogen and total phosphorous Sources / Notes Municipal and other sewage treatment plants, combined and separate sewer overflows, urban runoff, landfills, land disposal, industrial point sources, construction, land development / suburbanization, on-site sewage systems, channel modification. Great Miami River (Lower) TMDL report is in preparation. Not yet published, although nutrients listed as a special issue. The Great Miami River (lower) watershed was studied during A final study plan was published by OEPA in May

7 Organizational Chart The following organizational chart provides a visual representation of how the City of Springdale will accomplish the goals outlined in this Storm Water Management Program. Partnerships with other local storm water groups will continue to be considered to enhance specific components of the storm water management program, but the City will ultimately be responsible for implementing tasks associated with each of the six MCMs. 7

8 Minimum Control Measure 1: Public Education and Outreach on Storm Water Impacts 8

9 Minimum Control Measure 1: Public Education and Outreach on Storm Water Impacts The City of Springdale MS4 permit requires public education and outreach efforts to do the following: Shall implement a public education program to distribute educational materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges on water bodies and the steps that the public can take to reduce pollutants in storm water runoff. Performance Standards: Program shall include more than 1 mechanism and at least five different storm water themes or messages over the permit term, at least one theme shall be targeted to the development community, and reach at least 50% of the population. The following tables outline the best management practices (BMPs) selected by the City of Springdale to accomplish MCM 1. The City of Springdale has the legal authority to implement all identified BMPs. More than one mechanism will be implemented for public education and outreach. The five themes the City will focus on include the following: 1. Nutrient Pollution 2. Erosion Prevention and Sediment Control (Targeted to the Development Community) 3. Residential Storm Water Management 4. Litter and Trash 5. Hazardous Waste Disposal The City expects to reach at least half of its population over the permit term through the implementation of the following BMPs. BMP Type: Hard-Copy Outreach Materials Description of BMP: The City will develop, print, and distribute at least one brochure or fact sheet on each storm water theme over the five-year permit term. The City will also publish at least one article annually in the City-published newsletter about the impacts of storm water runoff.

Measureable Goal Track the number of brochures distributed over the permit term, and document any specific City events where brochures are distributed to the public. Document the number of press releases or news articles published over the permit term, with a goal of at least one article per year during the permit term. Schedule and Frequency Ongoing Annually 9 Responsible Party City of Springdale Public Works Dept. City of Springdale Public Works Dept. Target Audience City residents, City employees, City businesses City residents

10 Rationale for BMP: Routinely providing written information on storm water topics to City residents, employees, and businesses will enhance public awareness of water quality issues. City-published newsletters reached the majority of the population within the City during the previous permit term, and this continues to be an effective public outreach activity. How BMP addresses TMDL: One of the target themes for the outreach materials will be focused on nutrients to support the Mill Creek TMDL objectives. BMP Type: Web-Based Storm Water Materials Description of BMP: The City will continue implementing a web-based storm water library of educational materials, via the City s website, to promote education and outreach of the storm water program and related issues. Various storm water themes will be posted on an annual basis, including an erosion prevention and sediment control theme targeted to the development community. Website links to the Ohio EPA TMDL website will be included, along with a link to the Mill Creek TMDL report. The City s storm water website is: Measureable Goal Track the number of website hits over the permit term. Schedule and Frequency Ongoing Responsible Party City of Springdale Public Works Dept. Target Audience City residents, local developers Rationale for BMP: Online communication continues to be an effective method to provide current storm water information to people of a wide variety of demographics. How BMP addresses TMDL: The website will be updated to include links to Ohio EPA s TMDL program and specific links to the Mill Creek and Great Miami River watersheds. Links to information about impacts of nutrients on water quality will also be added to the website. BMP Type: Participation in City-Wide Event Description of BMP: The City will present storm water runoff related information and themes at a minimum of one City-wide event on an annual basis. Themes are anticipated to included City maintenance and service activities that help prevent storm water pollution, such as the street sweeping program, catch basin cleaning program, and leaf collection program. Measureable Goal Document the number of people in attendance during the event. Schedule and Frequency Annually Responsible Party City of Springdale Public Works Dept. Target Audience City residents Rationale for BMP: The City-wide event allows residents an opportunity to engage directly with City staff responsible for administering the storm water program. How BMP addresses TMDL: One of the target themes for the City-wide event will be focused on nutrients to support the Mill Creek TMDL objectives. 10

How you will inform individuals and households about the steps they can take to reduce storm water pollution. Refer to the tables above for a description of the BMPs the City intends to implement to inform the public about storm water runoff pollution and ways to reduce pollution and improve water quality. ii. How you plan to inform individuals and groups on how to become involved in the storm water program (with activities such as local stream restoration activities). Website updates and City-published newsletters will be utilized to notify individuals about upcoming opportunities to get involved in the storm water program. iii. Who are the target audiences for your education program who are likely to have significant storm water impacts (including commercial, industrial and institutional entities) and why those target audiences were selected? Refer to the table above for a description of the target audiences. These audiences were selected because they represent a broad base including the public, City employees, City businesses, and developers. iv. What are the target pollutant sources your public education program is designed to address? Because the Mill Creek has an approved TMDL that emphasizes water quality impacts associated with nutrients, specific themes will be developed to educate the public about how nutrients can impact local streams. Information about other pollutants will be included during the permit term as well, such as sediments and bacteria. v. What is your outreach strategy, including the mechanisms (e.g., printed brochures, newspapers, media, workshops, etc.) you will use to reach your target audiences, and how many people do you expect to reach by your outreach strategy over the permit term. Refer to the tables above for detailed outreach strategies that are intended to reach the public, including City residents, City employees, City businesses, and local developers. The City expects to reach at least half of its population over the permit term. vi. Who (person or department) is responsible for overall management and implementation of your storm water public education and outreach program and, if different, who is responsible for each of the BMPs identified for this program. Refer to the tables above for the responsible party for each BMP included in the program. The City of Springdale Public Works Department is responsible for the implementation of the public education and outreach MCM. Partnerships with other local storm water groups will continue to be considered to enhance public education and outreach efforts, but the City will ultimately be responsible for implementing tasks associated with this MCM. 11

12 vii. How will you evaluate the success of this minimum measure, including how you selected the measurable goals for each of the BMPs? The measureable goals were selected to be specific, measureable, achievable and realistic. The City intends to evaluate the effectiveness of the public education and outreach BMPs by tracking and documenting information as described in the tables above. 12

13 Minimum Control Measure 2: Public Involvement/Participation 13

14 Minimum Control Measure 2: Public Involvement/Participation The City of Springdale MS4 permit requires the public involvement/participation efforts to do the following: Shall comply with State and local public notice requirements and satisfy this minimum control measure s minimum performance standards when implementing a public involvement/participation program. Performance Standards: Include, at a minimum, five public involvement activities over the permit term. The following tables outline the best management practices (BMPs) selected by the City of Springdale to accomplish MCM 2. The City of Springdale has the legal authority to implement all identified BMPs. The City intends to implement at least five public involvement activities over the permit term. BMP Type: City Programs for Residential Involvement Description of BMP: The City will continue to implement City-sponsored programs to encourage residential involvement for storm water quality improvement. These programs are anticipated to include the City s annual leaf collection program, and the collection of household hazardous waste from residents. The Public Works department performs leaf collection in the fall season, and this is a free service that is available to all residents. The City encourages the public to refrain from placing leaves in the street, which can cause localized flooding and potential water quality issues. Measureable Goal Implement the leaf collection program for City residents. Document the dates each year when the leaf collection program is initiated by the City. Implement the household hazardous waste program for City residents, including the collection of used motor oil. The quantity will be measured through the City s good housekeeping program. Schedule and Frequency Annually Annually Responsible Party City of Springdale Public Works Dept. City of Springdale Public Works Dept. Target Audience City residents City residents Rationale for BMP: Providing residents with an opportunity to utilize this free service from the City allows the public to be involved with storm water management and quality improvement through the effective prevention of leaves in the storm sewer system and local waterways. How BMP addresses TMDL: Prevention of leaves from entering the storm sewer system and local waterways can provide a benefit of reduced nutrients from the leaves. This would provide a benefit during the fall season when the program is implemented. 14

15 BMP Type: Pet Waste Bags at City Parks Description of BMP: The City will continue to provide bags for pet wastes at each City-owned park. The total number of stations where bags are provided for pet wastes is 10, with at least one station provided at every park. Measureable Goal Maintain pet waste disposal stations in public spaces. Schedule and Frequency Ongoing Responsible Party City of Springdale Parks and Recreation Dept. Target Audience City residents (pet owners, park users) Rationale for BMP: Involving the public in cleaning up after their pets provides value not only in keeping pollution out of the water, but also educating residents and keeping the Parks clean. How BMP addresses TMDL: No direct link to nutrient reduction goals of the Mill Creek TMDL. BMP Type: Stream Clean-Up Events Description of BMP: The City will participate and encourage the public to participate in at least one stream clean-up event annually during the permit term. Measureable Goal Document the number of volunteers participating in stream clean-up events. Schedule and Frequency Annually Responsible Party City of Springdale Public Works Dept. Target Audience City residents Rationale for BMP: Engaging the public in stream clean-up events provides opportunity for hands-on education and outreach while also cleaning up local streams.

17 Minimum Control Measure 3: Illicit Discharge Detection and Elimination 17

18 Minimum Control Measure 3: Illicit Discharge Detection and Elimination The City of Springdale MS4 permit requires the illicit discharge detection and elimination efforts to do the following: Shall develop, implement and enforce a program to detect and eliminate illicit discharges. Shall develop a comprehensive storm water system map, showing the location of all outfalls and the names and location of all waters of the United States that receive discharges from those outfalls; MS4 system (catch basins, pipes, ditches, detention/retention ponds, post construction water quality BMPs), and private water quality BMPs. Shall submit to EPA a list of HSTSs including addresses; a map of HSTS s including type and size of conduits that receive discharges. Shall effectively prohibit through ordinance, or other regulatory mechanism, illicit discharges including enforcement procedures. Shall development and implement a plan to detect and eliminate non-storm water discharges, including illegal dumping and HSTS. At a minimum this includes: i. Working with applicable agencies and/or departments to identify HSTS s that could be connected to central sewers, and require connection for any HSTS not operating properly. ii. iii. iv. Working with the health department to develop a proactive O&M program. Actively investigating contamination sources during dry weather screening. Evaluating the planned/possible installation of sewers in areas with high densities of HSTS s. Shall inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste. Shall address the following categories of non-storm water discharges or flows if identified as significant contributors of pollutants: water line flushing, landscape irrigation, diverted stream flows, rising ground waters, uncontaminated ground water infiltration, uncontaminated pumped ground water, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, street wash water, and discharges or flows from firefighting activities. Performance Standards: Initial dry weather screening of all storm water outfalls over the permit term. Establish priorities and goals for long-term system wide surveillance of MS4. System map shall be updated as needed. The following tables outline the BMPs selected by the City of Springdale to accomplish MCM 3. The City of Springdale has the legal authority to implement all identified BMPs. 18

19 BMP: Update Storm Sewer System Mapping Description of BMP: The City has already developed a comprehensive mapping database of the existing storm sewer system. The database includes catch basins, pipes, ditches, flood control facilities, post-construction water quality BMPs, storm water outfalls, and receiving streams. The City intends to continue updating the map as necessary to include any new storm sewer system data from new development or redevelopment projects. The City also intends to add available information on the only two remaining home sewage treatment system (HSTS) within the City. Implementation Measureable Goal Responsible Party Schedule and Frequency Document any new information added to the storm sewer system mapping database during the permit term. Ongoing City of Springdale Public Works Dept. Rationale for BMP: Updating the storm system mapping with information on future development and redevelopment projects will continue to provide the City with a detailed database of the storm sewer system mapping information. How BMP addresses TMDL: No direct link to nutrient reduction goals of the Mill Creek TMDL, but having an accurate map can be beneficial in the future if nutrient loadings need to be estimated. BMP: Dry-Weather Screening of Storm Water Outfalls Description of BMP: The City will conduct dry-weather screening of all known storm water outfalls during the permit term. The City has a dry-weather screening reporting form to assist with the dry-weather screening of outfalls. Implementation Measureable Goal Responsible Party Schedule and Frequency Track the location and number of outfalls screened for illicit discharges during dry weather. All outfalls will be screened at least once during the permit term. City of Springdale Public Works Dept. Rationale for BMP: Screening storm water outfalls will assist the City in identifying illicit discharges throughout the storm sewer system. How BMP addresses TMDL: Dry-weather screening of outfalls for illicit discharges will ultimately improve water quality once resolved, however this will not directly impact the nutrient loadings in the Mill Creek TMDL. 19

20 BMP: Implementation of Illicit Discharge Detection and Elimination Program Description of BMP: The City will continue implementing its illicit discharge detection and elimination program to eliminate illicit discharges within the storm sewer system. The City has already developed and implemented an illicit discharge ordinance. This is Ordinance No , which adopted Section of the Springdale Codified Ordinances ( Measureable Goal Maintain existing ordinance prohibiting illicit discharges including enforcement procedures. Document the number of illicit discharge reports identified and resolved. Implementation Schedule and Frequency Ongoing All reports of illicit discharges will be investigated and resolved. Responsible Party City of Springdale Public Works Dept. City of Springdale Health Department City of Springdale Public Works Dept. City of Springdale Health Department Rationale for BMP: Eliminating illicit discharges results in a successful program. How BMP addresses TMDL: Eliminating illicit discharges will improve water quality, however this will not directly impact the nutrient loadings in the Mill Creek TMDL. MCM 3 Decision Process Rationale Statement The rationale statement shall include the following information, at a minimum: i. How you will develop a comprehensive storm sewer map showing the location of all outfalls and the names and location of all receiving waters. Describe the sources of information you used for the maps, and how you plan to verify the outfall locations with field surveys. If already completed, describe how you developed this map. Also, describe how your map will be regularly updated. The City has already developed a comprehensive mapping database of the existing storm sewer system. The database includes catch basins, pipes, ditches, flood control facilities, post-construction water quality BMPs, storm water outfalls, and receiving streams. The City developed the map based on a combination of comprehensive field data collection and the integration of information from record drawings from new development and redevelopment projects. The City intends to continue updating the map as necessary to include any new storm sewer system data from new development or redevelopment projects. The City also intends to add available information on the only remaining home sewage treatment system (HSTS) within the City. The City will utilize additional City resources to keep GIS shapefiles updates as changes are needed. ii. The mechanism (ordinance or other regulatory mechanism) you will use to effectively prohibit illicit discharges into the MS4 and why you chose that mechanism. If you need to develop this mechanism, describe your plan and a schedule to do so. If your ordinance or regulatory mechanism is already developed, include a copy of the relevant sections with your program. 20

21 The City will continue implementing its illicit discharge detection and elimination program to eliminate illicit discharges within the storm sewer system. The City has already developed and implemented an illicit discharge ordinance. This is Ordinance No , which adopted Section of the Springdale Codified Ordinances ( The City chose to use the ordinance as its mechanism to enforce the illicit discharge program because it allows the City to impose penalties for non-compliance. A copy of this ordinance is included as Appendix A of this SWMP document. iii. Your plan to ensure through appropriate enforcement procedures and actions that your illicit discharge ordinance (or other regulatory mechanism) is implemented. The City s Ordinance includes penalties for non-compliance this is the enforcement mechanism. Through the dry-weather screening of outfalls, the City will implement a plan to detect the source of any illicit discharges, then ultimately use the ordinance if necessary to implement enforcement procedures. iv. Your plan to detect and address illicit discharges to your system, including discharges from illegal dumping and spills. Your plan shall include dry weather field screening for non-storm water flows and Ohio EPA recommends field tests of selected chemical parameters as indicators of discharge sources. You shall describe the mechanisms and strategies you will implement to ensure outfalls which have previously been dry-weather screened will not have future illicit connections. Your plan shall also address on-site sewage disposal systems (including failing on-lot HSTSs and off-lot discharging HSTSs) that flow into your storm drainage system. Your description shall address the following, at a minimum: 1. Procedures for locating priority areas which include areas with higher likelihood of illicit connections (e.g., areas with older sanitary sewer lines, for example) or ambient sampling to locate impacted reaches; Priority areas will be located by considering areas with concentrated resident complaints/reports, and areas of the system noted by City staff as a possible concern. The City has only two remaining HSTSs, so there are no longer clusters of HSTSs that could be used in a prioritization of areas with potential for higher illicit discharges. 2. Procedures for tracing the source of an illicit discharge, including the specific techniques you will use to detect the location of the source; City crews have the ability to provide general field investigations, CCTV inspection, dye testing, and smoke testing to help locate the source of illicit discharges. Water quality sampling may also be utilized where needed. 3. Procedures for removing the source of the illicit discharge. Illicit discharges will be resolved on a case-by-case basis given the unique nature of each situation. 4. Procedures for program evaluation and assessment. 21

22 The dry-weather screening of all storm sewer system outfalls will provide an opportunity to assess the illicit discharge detection and elimination program. v. How you plan to inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste. Include in your description how this plan will coordinate with your public education minimum measure and your pollution prevention/good housekeeping minimum measure programs. The hazards of illicit discharges will be a topic or theme that is covered under the hardcopy outreach materials and web-based storm water material BMPs described under MCM 1 in this SWMP document. vi. Who is responsible for overall management and implementation of your storm water illicit discharge detection and elimination program and, if different, who is responsible for each of the BMPs identified for this program. Refer to the tables above for the responsible party for each BMP included in the program. The City of Springdale Public Works Department is responsible for the implementation of the illicit discharge detection and elimination MCM. vii. How you will evaluate the success of this minimum measure, including how you selected the measurable goals for each of the BMPs. The measureable goals were selected to be specific, measureable, achievable and realistic. The City intends to evaluate the effectiveness of the illicit discharge detection and elimination BMPs by tracking and documenting information as described in the tables above. 22

23 Minimum Control Measure 4: Construction Site Storm Water Runoff Control 23

24 Minimum Control Measure 4: Construction Site Storm Water Runoff Control The City of Springdale MS4 permit requires the construction site storm water runoff control efforts to do the following: Shall develop, implement, and enforce a program to reduce pollutants in any storm water runoff to your small MS4 from construction activities that result in a land disturbance of greater than or equal to one acre including projects less than one acre that are part of a larger common plan of development. At a minimum this includes: i. Ordinance or other requirements for construction site operators to require erosion and sediment controls as well as sanctions to ensure compliance. ii. iii. iv. Requirements for construction site operators to implement appropriate erosion and sediment control BMPs.

25 Rationale for BMP: Standardized tools and updated program objectives will aid the City in the successful implementation of this MCM. How BMP addresses TMDL: Although the Mill Creek TMDL targets are focused on nutrients, construction and land development are listed as sources of water quality pollutants. As a result, the implementation of standardized tools and program updates can help address sedimentation issues. BMP: Construction Site Runoff Control Implementation Description of BMP: This BMP includes implementation of the program in accordance with the ordinances and regulations already in place. Measureable Goal Track the number of construction site inspections completed. Track the number of SWPPPs reviewed as part of plan review process. Track the number of construction runoff issues reported. Implementation Schedule and Frequency Ongoing Ongoing Ongoing Responsible Party City of Springdale Building Department City of Springdale Building Department City of Springdale Building Department Rationale for BMP: Implementation of construction site runoff plan review and inspection activities are critical for a successful construction site runoff control program. How BMP addresses TMDL: Although the Mill Creek TMDL targets are focused on nutrients, construction and land development are listed as sources of water quality pollutants. As a result, the implementation of standardized tools and program updates can help address sedimentation issues. MCM 4 Decision Process Rationale Statement The rationale statement shall include the following information, at a minimum: i. The mechanism (ordinance or other regulatory mechanism) you will use to require erosion and sediment controls at construction sites and why you chose that mechanism. If you need to develop this mechanism, describe your plan and a schedule to do so. If your ordinance or regulatory mechanism is already developed, include a copy of the relevant sections with your SWMP description. The City has already developed and implemented an ordinance with requirements for erosion prevention and sediment control measures. This is Chapter 151 of the City s Codified Ordinances ( The City chose to use the ordinance as its mechanism to enforce the construction site runoff control program because it allows the City to impose penalties for non-compliance. A copy of this ordinance is included as Appendix B of this SWMP document. ii. Your plan to ensure compliance with your erosion and sediment control regulatory mechanism, including the sanctions and enforcement mechanisms you will use to ensure compliance. Describe your procedures for when you will use certain 25

26 sanctions. Possible sanctions include non-monetary penalties (such as a stop work orders), fines, bonding requirements, and/or permit denials for non-compliance. Chapter 151 of the City s Codified Ordinances includes penalties for non-compliance this is the enforcement mechanism. iii. Your requirements for construction site operators to implement appropriate erosion and sediment control BMPs and control waste at construction sites that may cause adverse impacts to water quality. Such waste includes, but is not limited to, discarded building materials, concrete truck washouts, chemicals, litter, and sanitary waste. All requirements are detailed in Chapter 151 of the City s Codified Ordinances. iv. Your procedures for pre-construction storm water pollution prevention plan review which incorporate consideration of potential water quality impacts. Describe the estimated number of sites that will have pre-construction site plans reviewed. All proposed construction sites in the City are required to go through the plan review process which includes the development of a SWPPP for erosion control. As part of this permit cycle, a checklist will be developed to further standardize the plan review process. v. Your procedures for receipt and consideration of information submitted by the public. Consider coordinating this requirement with your public education program. Information submitted by the public related to construction erosion issues are inspected by the City of Springdale staff, and the City coordinates with the contractor to resolve the issue. vi. Your procedures for site inspection and enforcement of control measures, including how you will prioritize sites for inspection. The City of Springdale Building Department is responsible for conducting monthly inspections of all active construction sites, and quarterly inspections on all inactive sites, and additional inspections as needed. vii. Who is responsible for overall management and implementation of your construction site storm water control program and, if different, who is responsible for each of the BMPs identified for this program. The City of Springdale Building Department is responsible for the review and approval of plan submittals including SWPPPs, as well as site inspections. viii. Describe how you will evaluate the success of this minimum measure, including how you selected the measurable goals for each of the BMPs. The measurable goals were selected to be specific, measurable, achievable and realistic. The City intends to evaluate the effectiveness of the construction site runoff control BMPs by tracking and documenting information as described in the tables above. 26

27 Minimum Control Measure 5: Post-Construction Storm Water Management in New and Redevelopment 27

28 Minimum Control Measure 5: Post-Construction Storm Water Management in New and Redevelopment The City of Springdale MS4 permit requires the post-construction storm water management in new and redevelopment efforts to do the following: Shall develop, implement, and enforce a program to address storm water runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development. Shall develop and implement strategies which include a combination of structural and/or non-structural BMPs. Shall use an ordinance, or other regulatory mechanism, to address postconstruction runoff from new and redevelopment. Shall ensure adequate long-term operation and maintenance of BMPs. Performance Standards: Post construction SWMP shall include a pre-construction SWPPP review of all projects which disturb greater than 1 acre. Site shall be inspected to ensure controls are installed per requirements. Program shall ensure long term O&M plans are developed and agreements are in place. The following tables outline the best management practices (BMPs) selected by the City of Springdale to accomplish MCM 5. The City of Springdale has the legal authority to implement all identified BMPs. BMP: Tools and Program Update Description of BMP: The City has already developed and implemented an ordinance with requirements for post-construction storm water runoff control measures. This is Chapter 151 of the City s Codified Ordinances ( The City will focus on implementing tools and program updates to meet this MCM. Measureable Goal Develop a storm water plan review checklist to assist City staff with reviews. Evaluate and update post construction BMP inspection program. Review existing ordinances and guidelines and update as needed. Implementation Schedule and Frequency To be developed by Year 3 of permit term. Ongoing Ongoing Responsible Party City of Springdale Building Department City of Springdale Building Department City of Springdale Building Department 28

29 Rationale for BMP: Standardized tools and updated program objectives will aid the City in the successful implementation of this MCM. How BMP addresses TMDL: Although the Mill Creek TMDL targets are focused on nutrients, construction and land development are listed as sources of water quality pollutants. As a result, the implementation of standardized tools and program updates can help address sedimentation issues. BMP: Post-Construction Runoff Control Implementation Description of BMP: The City will continue implementation of the post-construction storm water runoff control program in accordance with the ordinances and regulations already in place. Implementation Schedule Measureable Goal Responsible Party and Frequency Track the number of privately owned post-construction BMPs installed. Track the number of City owned post-construction BMPs installed. Track the number of private maintenance agreements put in place. Track the number of postconstruction BMPs inspected. Ongoing Ongoing Ongoing Ongoing City of Springdale Building Department City of Springdale Building Department City of Springdale Building Department City of Springdale Building Department Rationale for BMP: Ongoing management and implementation of the post construction program is the key to the program being successful and impactful. How BMP addresses TMDL: Program management and implementation will keep the designers and contractors accountable for the proper design and installation of BMPs which will provide water quality benefits to help meet the TMDLs. MCM 5 Decision Process Rationale Statement The rationale statement shall include the following information, at a minimum: i. Your program to address storm water runoff from new development and redevelopment projects. Include in this description any specific priority areas for this program. The City of Springdale requires by ordinance all new and redevelopment projects that disturb greater than 1 acre to implement post-construction storm water runoff control, both for water quantity and water quality. A copy of this ordinance is included as Appendix B of this SWMP document. ii. How your program will be specifically tailored for your local community, minimize water quality impacts, and attempt to maintain pre-development runoff conditions. 29

30 Per the City s storm water management ordinance, the designer/contractor must submit a detailed SWPPP including post-construction storm water control techniques with sizing calculations and drawings. The City then reviews the submittal and coordinates with the designer/contractor to address any deficiencies. This site-specific review by City staff is the component that allows the program to be specifically tailored for the local community. The City is already almost completely developed, as evidenced by no new development over one acre occurring over the last several years. There are a few remaining green space areas that could ultimately be developed in the future, but most of the postconstruction storm water management facilities in the future could be due to redevelopment projects. iii. Any non-structural BMPs in your program, including, as appropriate: green infrastructure storm water management techniques, policies and ordinances that provide requirements and standards to direct growth to identified areas, protect sensitive areas such as wetlands and riparian areas, maintain and/or increase open space (including a dedicated funding source for open space acquisition), provide buffers along sensitive water bodies, minimize impervious surfaces, and minimize disturbance of soils and vegetation; policies or ordinances that encourage infill development in higher density urban areas, and areas with existing storm sewer infrastructure; education programs for developers and the public about project designs that minimize water quality impacts; and other measures such as minimization of the percentage of impervious area after development, use of measures to minimize directly connected impervious areas, and source control measures often thought of as good housekeeping, preventive maintenance and spill prevention. As indicated above, The City is already almost completely developed. The City s storm water management ordinance includes language references to the latest edition of the Ohio Department of Natural Resources (ODNR) Rainwater and Land Development Manual and the Ohio Department of Transportation (ODOT) Location and Design Manual as references for post-construction storm water management design. The City s Building Official also maintains a current list of the City of Springdale s Post-Construction Best Management Practices. iv. Any structural BMPs in your program, including, as appropriate: green infrastructure storm water management techniques, storage practices such as wet ponds and extended-detention outlet structures; filtration practices such as grassed swales, bioretention cells, sand filters and filter strips; and infiltration practices such as infiltration basins and infiltration trenches. The City has mapped all of the structural post-construction storm water BMPs that have been installed within the City on previous new development and redevelopment projects. The City is currently in the process of converting the information in the GIS database of these post-construction BMPs from a point shapefile to a polygon shapefile to better represent the footprint of the BMP. v. The mechanisms (ordinance or other regulatory mechanisms) you will use to address post-construction runoff from new developments and redevelopments and why you chose the mechanism(s). If you need to develop a mechanism, describe your plan and a schedule to do so. If your ordinance or regulatory mechanism is 30

31 already developed, include a copy of the relevant sections with your program. The City has already developed and implemented an ordinance with requirements for post-construction storm water runoff control measures. This is Chapter 151 of the City s Codified Ordinances ( The City chose to use the ordinance as its mechanism to enforce the post-construction storm water runoff control program because it allows the City to impose penalties for noncompliance. vi. How you will ensure the long-term operation and maintenance (O&M) of your selected BMPs. Options to help ensure that future O&M responsibilities are clearly identified include an agreement between you and another party such as the postdevelopment landowners or regional authorities. The City s ordinance requires the submittal of a maintenance schedule for postconstruction storm water management practices. Operation and maintenance requirements are shown on the property deed or covenants that are included with the property. Through easements, the City has the ability to conduct inspections of postconstruction storm water management practices and the ordinance is used to enforce corrective measures if any deficiencies are identified. vii. Who is responsible for overall management and implementation of your postconstruction SWMP and, if different, who is responsible for each of the BMPs identified for this program. The City of Springdale Building Department is responsible for the review and approval of post-construction storm water management practices, as well as site inspections. viii. How you will evaluate the success of this minimum measure, including how you selected the measurable goals for each of the BMPs. The measureable goals were selected to be specific, measureable, achievable and realistic. The City intends to evaluate the effectiveness of the post-construction storm water runoff control program by tracking and documenting information as described in the tables above. 31
