Shreeve, Interim Water Services Director Q rv--vw., I '1' Date 2 City of Peoria Stormwater Management Program May 2019 3 Stormwater Management Program This Stormwater Management Program has been revised by the City of Peoria (City) to incorporate changes and satisfy the requirements of the Clean Water Act (CWA) in accordance with the Arizona Department of Environmental Quality's (ADEQ) Arizona Pollutant Discharge Elimination System (AZPDES) General Permit Number AZG2016-002 (Permit). The Permit was issued by ADEQ effective on September 30, 2016, and continues until the Permit expires on September 29, 2021. In the event, ADEQ does not issue a new Permit by September 29, 2021, the permit will be administratively continued until a new permit is issued. This document makes some changes to and clarifies actions identified in the SWMP issued on May 2017, and along with comparable revisions to the Notice of Intent submitted at the time of its issuance will result in clarity and consistency in the City's program that was previously missing. 3.1 Regulatory Background AZPDES permit (AZG2016-002) is established by ADEQ pursuant to the CWA (Section 402(p)(3)(iii)) to ensure that pollutant discharges from small municipal separate storm sewer systems (MS4s) are reduced to the maximum extent practicable (MEP), protect water quality, and satisfy the appropriate water quality requirements of the CWA. ADEQ's 2002 AZPDES general permit required small MS4s to develop and implement stormwater management programs (SWMPs) designed to control pollutants to the MEP and protect water quality. This general permit builds on the requirements of the previous general permit. 3.2 2016 Arizona Pollutant Discharge Elimination System (AZPDES) Small MS4 General Permit This Stormwater Management Plan (SWMP) has been developed by the City of Peoria and a revised Notice of Intention (NOi) was submitted, see appendix B, in order to fulfill the requirements for compliance with the 2016 AZPDES Small MS4 General Permit, which became effective on September 30th , 2016. This SWMP addresses the six Minimum Control Measures (MCMs) established by the EPA: 1. 2. 3. 4. 5. Public Education and Outreach Public Involvement and Participation Illicit Discharge Detection and Elimination {IDDE) Program Construction Activity Stormwater Runoff Control Post-Construction Stormwater Management in New Development and Redevelopment 6. Pollution Prevention and Good Housekeeping for Municipal Operations 3 City of Peoria Stormwater Management Program May 2019 The BMPs associated with each of the six MCMs are identified in the SWMP for the City of Peoria. Each BMP includes a description and measurable goals to assess the effectiveness and level of implementation. Responsible departments, target audience, and metrics are also included for each BMP. The Responsible Party from each department are listed elsewhere in the document. The intent of the SWMP is to reduce the discharge of pollutants from the municipal separate storm sewer system {MS4) to the "maximum extent practicable" (MEP). The City of Peoria will be responsible for the administration and implementation of this SWMP and will remain in a regulatory role regarding illicit discharges, implementation of BMPs at construction sites, functionality of stormwater infrastructure, and adequate controls at commercial establishments, as necessary, within the City. In order to evaluate the effectiveness of the SWMP the City will conduct an annual review of the identified best management practices and report any updates in the annual report. The annual report will provide an update on the progress towards meeting the measurable goals including a BMP inventory and an implementation schedule. 3.3 Organization of SWMP This SWMP has been organized into eight sections with their respective appendices. Each section is briefly described below: Section 1 Executive Summary-A summary of the NPDES permit program and the organization of the SWMP.

Section 5.7 Pollution Prevention and Good Housekeeping for Municipal Operations-The operations for reducing pollution from routine municipal operations and the City staff's training programs for stormwater pollution prevention are described in this section. Section 6 Annual Program Evaluation Protocol -This section describes the procedure for reviewing and evaluating the City's SWMP. The section also summarizes the steps for preparing the annual report. Based on necessity, the SWMP will be updated periodically, by the City, to maintain a stormwater quality management program. Minor updates will occur at the staff level and will consist of bookkeeping matters, such as changes in who is responsible for a specific BMP, etc. Major updates will include changes in the SWMP such as the implementation of new BMPs or the discontinuance of ineffective ones, policy changes, etc. PERMIT COVERAGE AREA This SWMP covers discharges from the City of Peoria. Figure 1 identifies the City of Peoria Limits and the urbanized area boundary based on the 2010 census. 5 City of Peoria Stormwater Management Program May 2019 City of Peoria, AZ D City Limits Durban Area �/61'1017 Figure 1: City of Peoria and Surrounding Urbanized Area 6 City of Peoria Stormwater Management Program May 2019 4 Program Management 4.1 Overview The Stormwater Management Program is an ongoing effort, which will be updated as necessary during the permit term. This section describes the overall objectives of the City's SWMP, some of the local issues specific to the City, departmental implementation of the SWMP, and an overview of the legal authority to implement and enforce the program. The mission of the City of Peoria is to provide excellent municipal services by anticipating community needs, creating partnerships, promoting sustainability, and embracing diversity. The City value statement states that we serve with integrity, embrace diversity, and are responsible stewards of taxpayer dollars and the natural environment. As part of the City's responsibility for the oversight of the design, construction, and maintenance of public and private infrastructure, the implementation of the SWMP will assist in fulfilling the City's mission and value statements. 4.2 Goals and Policy The goal of Peoria's SWMP is to reduce polluted stormwater runoff and protect its water resources through compliance with the AZPDES permit for small MS4s. The program is designed to aid in accomplishing this goal. The City of Peoria's stormwater program incorporates the six minimum control measures established by the EPA's Phase II final rule and the MS4 permit issued on September 30, 2016. The objectives of the SWMP are to: ■ ■ ■ ■ Along with the Notice of Intent be the guide to compliance with the MS4 Permit; Implement cost effective Best Management Practices (BMPs) that provide water quality benefits; Control pollutants that may adversely impact Peoria's receiving waters (New River and the Agua Fria River); and Maintain compliance with environmental laws and regulations, and remain compatible, and in coordination with other programs within the City. The implementation of the six minimum control measures specified in the Small MS4 Permit, and listed herein, will support these objectives through City policy and procedures. The City also recognizes the importance of the watershed approach in improving water quality. Therefore, the City will continue to work with neighboring jurisdictions in coordinating programs such as public outreach and education, attending meetings, participating in special studies, and reporting spills. 7 City of Peoria Stormwater Management Program May 2019 4.3 Discussion of Local Receiving Waters The City of Peoria is located within the Middle Gila Watershed. The majority of the streambeds are dry due to surface water diversions, groundwater pumping, and limited rainfall. The City receives approximately 7-9 inches of rainfall per year. Peoria has three main features that receive stormwater runoff. The first two are the Agua Fria River and New River, which both consist of dry riverbeds. The third feature is the ADOT drainage channel, which also discharges to New River. The North Peoria area discharges into the Agua Fria River, while the Central and South regions of Peoria discharge into the ADOT drainage channel and New River. Stormwater runoff from Peoria is collected and conveyed in both local municipal and private storm drain systems, open channels, washes, public and private streets, and other conveyances, before discharging into the rivers. Discharges from the City of Peoria must meet associated water quality standards to protect the designated beneficial uses of the river systems (see Table 1). There are no impairments identified in any of the receiving waters as it moves through the City of Peoria so no additional monitoring is required. There are approximately 260 outfalls to the Agua Fria River and the New River within the City's boundaries. Outfalls are updated annually, by the GIS Division, Information Technology Department, as necessary. Table 1: Receiving Water and Designated Beneficial Uses Receiving Water Designated Beneficial Use • Aquatic and Wildlife Ephemeral • Partial Body Contact Agua Fria River • Agricultural Livestock Watering • Aquatic and Wildlife Ephemeral • Partial Body Contact New River • Agricultural Livestock Watering This SWMP covers all stormwater runoff and discharges located within the City's urbanized area (see Figure 1). While much of the northern portion of the City of Peoria remains undeveloped, this area will continue to experience much growth in the future. This SWMP will serve as a comprehensive management tool to help maintain stormwater quality throughout the city. 8 City of Peoria Stormwater M anagement Program May 2019 4.4 Stormwater Management Responsibilities Table 2: Management Responsibilities: Department Responsible Party Development a n d Engineering Department Engineering Services Engineering Inspection Services Building Development 0 Building I nspections Public Works Department • Facilities • Fleet Maintenance • Solid Waste • Streets 0 Storm Water Maintena nce • Tra nsit Development and Engineering Director Deputy Engineering Director 0 Engineering l nsp Supervisor • Deputy Development Director 0 Buildi ng Official Public Works Di rector • Facilities Ma nager • Fleet Services Manager • Solid Waste Manager • Street Operations Manager 0 Street Maintenance Supervisor • Transit Supervisor Water Services Director • Planning and Operations Manager • Environmenta l Resources Ma nager • Plant Operations Manager • Field Operations Manager Planning and Com m u nity Development Director Com m u nity Services Director • Deputy Com m u n ity Services Director N eighborhood a nd H u man Services Director • Cod e Com plia nce Officer Fire Chief Chief Financial Officer IT Director • • • Water Services Department • Pla nning and Operations • Environmental Resources • Plant Operations • Field Operations Planning and Com m u nity Develop ment Department Com m u n ity Services Department • Parks/ROW/Sports Facilities N eighborhood a n d Human Services Department • Cod e Com p l i ance Fire Department Finance Department Information Technology ( IT) Department • Compliance with the City's stormwater man agement progra m is admin istered by the Water Services Department - Environmental Resou rces Division.

The City's program continues with the implementation of successful measures from the previous permit cycle. Some measures were moved to other locations in the Plan, where appropriate. Narrative descriptions and measurable goals for other measures have been re-written to clarify what needs to be done and by which department. There are also some new BMPs to help supplement the existing program. With the current stormwater management plan, the City will annually review best management practices and will eliminate those that are not effective and propose new practices when necessary. 5.2 MCM 1 - Public Education and Outreach The City of Peoria is required to implement a public education and outreach program that will distribute educational materials and provide outreach to the MS4 community. This program is required by Section 6.4. 1 of the Permit. The educational materials must provide messages for specific audiences regarding the impact of stormwater discharges within the community. Measurable goals must also be developed to assess the effectiveness of the BMPs. The purpose of the public education and outreach programs are to increase public knowledge regarding the impacts of stormwater discharges, change the behavior of the public, and identify ways they can reduce pollutants in stormwater by messaging through distribution of brochures, booklets, flyers, and postings to the City's webpage. The target audience for the City's public education and outreach campaign consists of residents, homeowners, commercial establishments, industry, the development community, and the general public. The City believes that when the target audience is educated about stormwater, greater support for, and assistance with, the program will occur. In addition, when the target audience is aware of the importance of stormwater pollution prevention, greater compliance with the goals of the program will be achieved, and a reduced pollutant load will reach the MS4 and waterways. The target pollutants for the public education and outreach campaign consist of sediment from construction; oil, grease, chemicals, and heavy metals from motor vehicles; pesticides, herbicides, and nutrients from lawns and gardens; viruses, bacteria, nutrients from pet waste and failing septic systems, trash and litter. Methods will be developed to evaluate the effectiveness of the educational and outreach programs and will be tied to the defined goals of the program. The message used for each 12 City of Peoria Stormwater Management Program May 2019 audience, the method of distribution, and the objective of changes in behavior and knowledge will be used to assess the overall effectiveness of the education program. The City will revise ineffective messages or distribution techniques. 5.2.1 Selected BMPs The City of Peoria has evaluated the public education and outreach requirements and implemented a program that is focused on informing residents and businesses of the importance of preventing stormwater pollution. Table 3 lists the selected BMPs, with a description of each BMP provided in this section.

Metricse: Listing of events participated in with the AZ Water Association 5.3 MCM 2 - Public Involvement and Participation The second mandated minimum control measure seeks the active participation and involvement of the public. The objective of this requirement is to provide opportunities to engage the public to participate in the review and implementation of the City's SWMP. The public involvement and participation requirements are outlined in Section 6.4.2 of the Permit. Getting the public to actively participate in events related to the stormwater program, and involving the public in the review of the SWMP is believed to result in increased support for the program. Increased support for the program will then lead to a reduction in pollutant loading in the stormwater. The City of Peoria public involvement and participation program allows the public to engage with the City on stormwater related issues, to understand key aspects of the program, and the opportunity to help shape it. It allows the City to leverage their own and citizen resources in implementing the program. 5.3.1 Selected BMPs The City of Peoria has evaluated the public involvement and participation component of their stormwater program and has identified BMPs to better inform the residents and businesses of the importance of preventing stormwater pollution.

This section describes the City's procedures for plan review, site inspection tracking, and stormwater enforcement at construction sites. The Construction Activity Stormwater Runoff Control requirements are in Section 6.4.4 of the Permit. The goal of the program is to prevent pollution of stormwater in the MS4 from construction site activities and wastes. Construction activity stormwater runoff control includes the following measures: • An ordinance or other regulatory mechanism that requires the use of sediment and erosion control practices. 26 City of Peoria Stormwater Management Program May 2019 ■ ■ ■ ■ ■ ■ ■ An inventory of all construction activities that disturb or will disturb one or more acres within the permitted area, including those that are less than one acre but are part of a larger common plan of development that will ultimately disturb greater than one acre. Written procedures for site inspections and enforcement of sediment and erosion control measures. Inspection frequency based on the following: o Phase of construction o Proximity to a receiving water; o Proximity to an impaired, not-attaining water or Outstanding Arizona Water; o Size of the construction activity (acreage disturbed); and o History of non-compliance (site or operator). Requirements to take all necessary follow-up actions to ensure compliance Requirements for construction operators to implement sediment and erosion control BMPs appropriate for the conditions at the construction activity. Examples include: Minimizing disturbed area and protecting natural resources; Stabilizing sites when complete or in holding pattern; Protecting slopes; Protecting storm drain inlets, and armoring all newly constructed outlets; Perimeter controls; Stabilized entrances and exits with vehicle tracking control; and Inspection of stormwater controls on site. The program must also provide education to contractors and construction personnel on erosion and sediment control best management practices requirements. The public should also have the opportunity to submit information and considerations for the program. 5.5.1 Selected BMPs The City of Peoria construction activity stormwater runoff control program is focused on reviewing construction activities during active construction. Key components to the construction program include construction plan reviews, issuance of grading and drainage permits, and construction site inspections during active construction. As a result of evaluation, the City of Peoria has identified BMPs to better inform the residents and businesses of the importance of preventing stormwater pollution from construction activities. The selected BMPs are listed in Table 6 and described in this section.

Once the grading and drainage plans are approved by the City, and prior to issuing a grading permit, the operator must provide a fully executed copy of the SWPPP and NOi to the City. The City will not issue a grading permit until copies of the SWPPP and NOi are submitted. After the Development and Engineering Department approves the construction plans, the applicant submits all necessary bonds, insurance, and other required documentation, and all fees are paid, they will issue construction permits. There will be site inspections during active construction, and after storm events. The City has the authority to cite operators of construction sites found to be out of compliance, MCM 4-1. Res ponsieble Deepartmente(s ): Development and Engineering Department Measuraeble Goalse: The City will track the number of SWPPPs and NOls reviewed with respective grading and drainage plans, the number of inspections conducted, enforcement actions taken, and enforcement actions resolved.

The post-construction requirements are in Section 6.4.5 of the Permit. The program will contain a regulatory mechanism that will specify that owners or operators of new development and redevelopment sites discharging to the MS4, shall design, install, and maintain post-construction stormwater controls. The controls must reduce or eliminate the discharge of pollutants from the site after construction activities are completed. Educational materials will be provided to development owners and operators to help increase awareness and knowledge of post-construction stormwater runoff. The program will include inspections to evaluate and approve post-construction stormwater controls. It will also contain an inventory system of all post-construction structural stormwater control measures installed and implemented at new development and redeveloped sites. These will include both public and private sector sites located within the permit area that discharge into the MS4. The inventory will be searchable by property location and other relevant criteria. 5.6.1 Selected BMPs The City of Peoria has evaluated the post-construction stormwater management in new development and redevelopment component of their stormwater program and has identified BMPs to address stormwater pollution from new development and redevelopment projects. The selected BMPs are summarized in Table 7, with a description of each BMP provided in this section. Table 7: MCM-5 Post-Construction Stormwater Management in New Development and Redevelopment BMP Summary Description BMP 31 City of Peoria Stormwater Management Program May 2019 MCM 5-1 MCM 5-2 MCM 5-3 MCM 5-4 Inspection Program Post Construction Stormwater Control Inventory Educational Materials for Post Construction Management in New Development and Redevelopment Post Construction Management Training MCM 5-1 - Inspection Program Descrieptione: The City will have inspection and enforcement procedures for new development and redevelopmerit. Stormwater discharges from new development and redevelopment sites have the potential to degrade water quality, from soil disturbance associated with construction, or from an increase in impervious surface cover. Stormwater control measures addressing post-construction discharges incorporate several different approaches to maintain and/or improve water quality. To remove pollutants from stormwater runoff, structures are installed to filter, slow, and treat drainage using various processes. These stormwater structures are called Best Management Practices, commonly referred to as BMPs. They are designed to reduce flooding, remove pollutants, and decrease the amount of runoff from stormwater that ultimately flows to our washes and rivers. Ensuring that these facilities function correctly requires long-term maintenance and inspections. The City has existing processes in place for development projects and capital improvement projects to assure site stabilization has occurred at the end of the construction period. As part of the acceptance or punch list inspection phase of the project, any outstanding stabilization measures are noted for the contractor. The sites are also re-inspected one year after acceptance as part of a warranty inspection at which time any remaining control measures such as silt fencing that has not been removed is done so at that time. Post-Construction Stormwater Management Program includes three distinct components: • Documentation - Inspections are a necessary and important part of the Post­ Construction Stormwater Management Program. The inspection forms will provide the necessary documentation to demonstrate when and what was inspected and notification to responsible party. 32 City of Peoria Stormwater Management Program May 2019 • Inspections 1. All post-construction stormwater BMPs shall be maintained by the entity responsible for its operations and maintenance. 2. The property owners are responsible for inspection, operation, and maintenance of privately owned stormwater facilities. 3. The Public Works Department inspects 20% of the publically owned stormwater infrastructure per year, to ensure proper operation and maintenance. 4. The Public Works Department will notify the Water Services Department of observations of polluted stormwater entering the City's MS4 from private stormwater infrastructure (illicit discharges) during the conduct of their O&M responsibilities. 5. The Water Services Department will investigate reports of polluted stormwater entering the City's MS4 from private development. 6. If corrective actions have not been implemented the inspector will document in the appropriate database and initiate enforcement pursuant to the City Code. • Maintenance-The effectiveness of post-construction stormwater control BMPs depends upon regular inspections and maintenance of all aspects of the facility. There are typically two types of BMP maintenance, referred to as routine maintenance and corrective maintenance. Corrective maintenance consists of repairs performed to correct a deficient part of the BMP facility as identified in the inspection. Maintenance action returns the BMP component to the original design conditions for proper function. Post-construction BMPs shall be maintained by the entity responsible for its operations and maintenance. Responsibility is determined by language included on the Dedication Statement found on the Final Plat. The operation and maintenance requirements follow the property regardless of property owner changes. Inspections, by the City, of post-construction BMPs operated and maintained by an entity other than the City (such as an HOA or commercial property owner) will be restricted to locations where they discharge into the City's MS4 and upon observing potentially polluted stormwater or illicit discharges, and will also be complaint driven through the Peoria Reporter App or hotline. Res ponsi ble De partment (s ): Public Works Department, Water Services Department. Measuraeble Goalse: The City will annually report 1) the number and percentage of storm sewer system assets inspected (public and private, as appropriate), included on the City inventory and included on the City's GIS maps; and 2) enforcement actions taken and resolved or referred for further enforcement. 33 City of Peoria Stormwater Management Program May 2019 Target Auediencee: Developers; Homeowners Associations, commercial property owner, City staff; general public Overarcehing Metrics The City will annually report the number of Final Letters of Acceptance (FLOAs), and track the annual number of Post Construction inspections, corrective actions, and complaints/incidents addressed. Metricse: The City will annually report the number of Post Construction inspections conducted, corrective actions and complaints/incidents resolved. MCM 5-2 - Post Construction Stormwater Control Inventory Descrieptione: The City will incorporate post-construction features into their Geographic Information System (GIS). All stormwater control BMPs are inventoried in GIS. As stated above Post Construction BMPs include; detention basins, retention basins, drywells, channels, culverts, and drainage pipes. Upon completion of projects, developers/contractors are required to deliver site as-built plans to the City prior to issuance of the Final Letter of Acceptance. The as-built plans are then incorporated into the City's GIS. As-built plans are typically input into the City's GIS system soon after being submitted so that stormwater infrastructure remains up to date. Res ponsieble Deepartmente(s ): Development and Engineering Department, Information Technologye- GIS Measuraeble Goalse: As the city obtains as-built drawings from developers, consultants, and/or contractors, the post construction features will be incorporated and tagged into the GIS system on an on-going basis. Target Auediencee: City inspectors; City staff; general public; HOAs Overarcehing Metricse: The City maintains a GIS database that is updated annually with post construction features, Metricse: Average time (in days) from submittal of final as-built drawings to update on GIS. MCM 5-3 - Educational Materials for Post Construction Management in New Development and Redevelopment 34 City of Peoria Stormwater Management Program May 2019 Desceriptione: The City will provide educational materials to private property owners and the general public on best management practices for post construction managem ent in new development and redevelopment. The City of Peoria maintains stormwater collection system components in public right-of-way, drainage easements, and on City owned property. It is the private property owner's responsibility to maintain stormwater collection system com ponents on such private property and to p revent or minimize discharges of pollutants to the public stormwater collection system. The intent of the City's Stormwater Best Management Practices - A Handbook for Developers, Owners and Operators is to assist private stormwater collection system owners in performing proper maintenance of the system com ponents and to inform private property owners of the requirements detailed in the Peoria City Code. Private property owners shall either directly or indirectly ensure that all necessary controls are in place and properly maintained to prevent non-stormwater discharges. Private property owners are encouraged to develop, implement, and maintain a program and/or procedure(s) that establish an inspection and maintenance plan to ensure that periodic inspections and associated maintenance is conducted in a timely manner. Inspection and maintenance procedures and appropriate fiduciary mechanisms should be outlined in the association's Conditions, Covenants, & Restrictions (CCRs) and the Final Grading and Drainage Report, and should detail who will inspect, what will be inspected, inspection frequency, recordkeeping, routine maintenance schedules, interim maintenance response procedures, response to hazardous spills, and illegal dumping procedures.
