Section F (Post-Construction Site Runoff Control) of the permit requires managing stormwater runoff from developments and ensuring that controls are in place to minimize the water quality impacts. The conditions of the permit also require pollution prevention and good housekeeping measures to reduce pollution from authorized stormwater discharges (Section G). In order to meet stormwater quality standards of the permit, permittees utilize stormwater control measures (SCMs), which are permanent structural devices that are designed and constructed to remove pollutants from stormwater runoff. For SCMs to work effectively, they must be inspected and maintained regularly. 1.2 Purpose of Document The City of Raleigh Stormwater Management Division maintains and tracks the compliance of more than 2,000 SCMs across the City. In order to execute its SCM program, the City of Raleigh implements two city programs: 1) the SCM Inspections Program, and 2) the Asset Management Program. The Asset Management Program is a team of City employees responsible for ensuring that all City-owned SCMs required under sections 9.2.2 B or E of the UDO are inspected, maintained, and functioning as designed. The purpose of this plan is to document the responsibilities and procedures of the Asset Management Program. For tracking and enforcement of SCMs required under sections 9.2.2 A, B, and E of the UDO, refer to the COR SCM Inspections Program O&M Plan. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 2-1 2 Organizational Structure The following section details the responsibilities of the Stormwater Management Division, defines service-level agreements (SLAs) with SCM-owning City departments, and provides the ordinances and legal authority that allows the City of Raleigh to implement the SCM maintenance and inspection program. 2.1 Roles/Responsibilities The Stormwater Management Division, which falls under the Engineering Services Department, is responsible for implementing all post-construction stormwater management requirements listed in the City’s MS4 permit by managing compliance of privately-owned and City-owned SCMs within the City of Raleigh’s jurisdiction that are required by the City’s development ordinances. A modified, abridged version of the Stormwater Management Division’s organizational structure is shown in Figure 2-1. City departments that own SCMs are responsible for the inspection and maintenance of their SCMs unless otherwise stated in an SLA with the Stormwater Management Division. Figure 2-1: Stormwater Management Division (Modified, Abridged Organizational Chart) City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 2-2 2.2 SLA Model Template & Best Practices To facilitate the long-term inspection and maintenance needs of City-owned SCMs, the Stormwater Management Division has established SLAs to define the roles and responsibilities of other City departments with SCMs. The purpose of an SLA is to document the roles and responsibilities of both the owning department and the Stormwater Management Division, as well as to detail which resources and budgets are in place to provide the level of service (LOS) and the support each City department will need to maintain its SCMs. The SLA also documents the processes to which owning departments must adhere, such as device planning and construction, as-built acceptance, contractor agreements, and documentation requirements, for their SCMs. The Stormwater Management Division uses a standard SLA template for all owning departments, but the roles and responsibilities of the owning departments may be modified to account for any department-specific limitations. An SLA model template is included in Appendix A of this plan. 2.3 Ordinances/Legal Authorities The Stormwater Management Division is authorized to implement its SCM O&M Program through the City of Raleigh Unified Development Ordinance (UDO), Chapter 1.1, Article 1.1 Legal Provisions and Chapter 9, Article 9.2.2 Stormwater Management, Sections G and H. The UDO gives the City legal authority to construct or reconstruct, install, inspect, and maintain all post-construction stormwater devices required under sections 9.2.2 A, B, and E on both City and private property. Furthermore, it requires landowners to maintain all on-site stormwater devices unless those devices are accepted for maintenance by the Stormwater Management Division. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 3-1 3 Tracking To ensure uniform tracking of all pertinent information for SCMs required under sections 9.2.2 A, B, and E of the City’s UDO, the SCM Inspections Program maintains an internal Excel spreadsheet called the “Tracking Spreadsheet” as well as a Geographic Information System (GIS) database in ArcGIS Online called the “Tracking Layer”. The Asset Management Program is not responsible for updating or maintaining the “Tracking Spreadsheet” or “Tracking Layer.” For additional information on SCM tracking, please refer to the COR SCM Inspections Program O&M Plan. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-1 4 Inspections The following section discusses the various inspection types and the expected frequency; inspection preparation and safety; inspection checklists available for various types of SCMs; and inspection documentation. 4.1 Schedule/Frequency The City’s Stormwater Management Division manages compliance of SCMs within the jurisdiction of the City of Raleigh that are required under sections 9.2.2 A, B, and E of the UDO. The Asset Management Program is responsible for the inspection and maintenance of City-owned SCMs required under sections 9.2.2 B and E of the UDO, which undergo routine and annual inspections as specified in Sections 4.1.1 and 4.1.2. The City also developed an SCM Inspections standard operating procedure (SOP), which is included as Appendix B of this plan. 4.1.1 Routine Inspections The Asset Management Program aims to conduct routine inspections of City-owned SCMs on a quarterly basis to monitor for any maintenance needs and to ensure proper function. Routine inspections for City-owned SCMs are conducted by the owning departments, unless stated otherwise in the department’s SLA. The routine inspection checklists are provided in Appendix C-1 of this plan. 4.1.2 Annual Inspections Annual inspections are performed every 12 months for SCMs required under the City of Raleigh’s UDO section 9.2.2 (section A, B, and E) and cannot be conducted more than 90 days prior to the site’s anniversary date. Retrofit SCMs are not required by the City’s MS4 permit to undergo annual inspections. Annual inspections for City-owned SCMs are conducted by the owning departments unless stated otherwise in the department’s SLA. Annual inspections are comprehensive and require evaluation of each SCM component to demonstrate that the device is performing properly and is in compliance with the approved stormwater control O&M plan. Annual inspections must be conducted by a North Carolina professional engineer, surveyor, or landscape architect. The City has developed annual inspection checklists for use by professionals when completing annual inspections of City-owned devices. Following inspection, an annual inspection report must be completed and submitted to the SCM Inspections Program for review City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-2 and acceptance. Annual inspection reports must be certified by the North Carolina professional engineer, surveyor, or landscape architect who performed the inspection. More information regarding annual inspections and the annual inspection checklists developed by the City can be found in Section 4.3 below. 4.2 Inspection Preparation and Safety Prior to conducting any SCM inspection, inspectors should prepare by reviewing site- specific documentation, including as-built drawings, SCM specifications, maintenance requirements, planting plans, and past inspection/maintenance records, when available. All available site-specific documents are stored digitally on the City’s server. Inspectors should follow the local weather forecast to avoid inspecting devices directly following a significant rain event. For rain events totaling more than 1-inch, inspectors should allow 24 to 48 hours before conducting an inspection to ensure that all device components are clear, visible, and accessible. Prior to performing in-field inspections, safety precautions should be taken as needed, including, but not limited to; avoiding hazardous weather conditions, wearing appropriate personal protective equipment (PPE), and avoiding unsafe conditions. Inspectors should avoid confined spaces unless trained and equipped with proper PPE and required permits. 4.3 Annual Inspection Checklists The Asset Management Program uses device-specific annual inspection checklists when inspecting City-owned SCMs. A g eneral SCM inspection checklist has also been developed to cover new SCM types implemented in the future. The annual inspection checklists are provided in Appendix C-2 of this plan and include the following SCM types: • Bioretention basin • Constructed wetland • Dry pond • Filterra • Level spreader • Sand filter • Swale City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-3 • Underground detention • Wet pond • Generic checklist Each checklist includes a General section that is used to document relevant site information, such as the date of inspection, current weather conditions, the inspector’s name, rainfall amounts in the last three days, the anniversary date for the device, and the date of last inspection, as shown in Figure 4-1. Figure 4-1: General Information for Annual Inspection Checklists The other sections of the form are specific to each device type and ask a series of device-specific questions to determine whether each component is functioning properly or in need of maintenance. To provide more information on the extent of maintenance needed, each question has a two-part answer. The inspector will answer Yes, No, or Not Applicable and then select the appropriate action, which could be Monitor, Investigate, or Repair as shown in Figure 4-2. Figure 4-2: Area of SCM to be Assessed for Annual Checklists City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-4 For example, if the outlet structure of a wet pond is being inspected, the inspector will be asked to assess whether “Trash, sediment, debris is present at or obstructing the inlet.” If there is substantial sediment blocking the inlet at the time of inspection, the inspector would answer “Yes” and “Repair” as shown in Figure 4-3. Figure 4-3: Inlet Points for Annual Inspection Checklists Each individual component will receive a status code of Fully Functional (FF), Partially Functional (PF), or Not Functional (NF) based on the answers as shown in Figure 4-4. Figure 4-4: SCM Status Code Options for Annual Inspection Checklist At the conclusion of each inspection checklist is an overall SCM evaluation (see Figure 4-5 below), which requires the inspector to summarize all routine and immediate maintenance needs (if applicable), assess the probability and consequence of SCM failure, and provide a LOS score for the entire device. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-5 Figure 4-5: Overall SCM Evaluation for Annual Inspection Checklists The annual inspection checklists ensure that each component across all devices is thoroughly inspected and allow the City to track a device’s improvement or decline over time. The inspection checklists are reviewed and updated as needed on an annual basis by the City team as part of the continuous improvement process. 4.4 Documentation of Completed Inspections Completed routine inspections are documented in CityWorks, an Asset Management System used by the City to track routine SCM inspections and maintenance. A work- order generation capability for SCM maintenance workflow is currently under development for CityWorks. Annual inspection reports for SCMs required under sections 9.2.2 B and E of the UDO can be submitted to the SCM Inspections Program for approval 90 days prior to the site’s anniversary date in PDF format. Annual inspection reports must be certified by the North Carolina professional engineer, surveyor, or landscape architect who performed the inspection. Annual inspection reports must be submitted with the Stormwater Device City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 4-6 Annual Inspection Report Summary (Form-501). Once the annual inspection report has been approved and accepted by the SCM Inspections Program, the report will be signed by City staff and returned to the submitter and the acceptance of the annual inspection report will be tracked in the “Tracking Spreadsheet.” All signed annual inspection reports are retained for 6 years on the City’s server. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 5-1 5 Maintenance The Asset Management Program is responsible for maintaining SCMs located on City property, pursuant to the SLA with the owning department. The Asset Management Program identifies devices in need of maintenance, then prioritizes, budgets, and implements routine maintenance and major repairs in order to ensure all devices are maintained properly and functioning as designed. The following section discusses routine maintenance; specialized maintenance; major repairs and rehabilitation; contractor qualifications; general and SCM-specific routine maintenance guidance documents; the notification process for immediate corrective actions; and documentation of completed maintenance and costs. 5.1 Routine Maintenance Routine maintenance of City-owned SCMs will be accomplished by City maintenance staff or qualified maintenance contractors and tracked in CityWorks. Routine maintenance items are continuously addressed by maintenance staff or by contractors under routine maintenance contracts. Additional routine maintenance items can be identified during routine and annual inspections and would then be incorporated into ongoing routine maintenance activities. The City has developed technical guidance and specifications for routine maintenance of SCMs. The maintenance documents include a general section that addresses maintenance requirements for any type of SCM and additional sections that provide SCM-specific guidance. The maintenance documents specify required frequency of routine maintenance items, a framework for documentation of these items, and limited specifications for materials and methods. 5.2 Specialized Maintenance Specialized maintenance of City-owned SCMs will be accomplished by contractors with expertise in the specific maintenance needed. These maintenance needs may include, but are not limited to, aquatic vegetation maintenance or removal, tree care, pest control, etc. Specialized maintenance needs can be identified during routine and annual inspections. Any specialized SCM maintenance performed will be tracked in CityWorks. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 5-2 5.3 Major Repairs & Rehabilitation Major repairs or rehabilitation needs for City-owned SCMs are identified during routine and annual inspections as immediate corrective actions. These types of repairs are typically infrequent, costly, and are unable to be addressed by routine maintenance. SCMs in need of major repairs or rehabilitation are prioritized based on LOS scores which are given by the inspector (see Figure 4-5) during annual SCM inspections. The complexity of maintenance work as well as the consequences and probability of SCM failure are considered during prioritization. Depending on the level of effort, expertise required, and City staff availability, the major repairs will either be assigned to City Maintenance staff or to a qualified maintenance contractor. If the maintenance work is to be assigned to a contractor, the Asset Management Program will develop a Repair & Rehabilitation (R&R) Plan that is SCM-specific. An R&R Plan is a construction document that typically consists of general notes; specific restoration and maintenance activities; and annotated original design plans (if available) showing the locations and extent of needed repairs or modifications identified by the Asset Management Program. R&R Plans are not intended to be used to completely redesign or rebuild SCMs. Once an R&R plan has been developed and finalized, maintenance work will be awarded to a contractor through a bidding process; see Section 5.4 for maintenance contractor qualifications. As with other maintenance work, these activities will be documented in CityWorks. 5.4 Maintenance Contractor Qualifications The City is currently developing a process to identify and maintain a group of qualified contractors for SCM maintenance. The process will include development and use of the appropriate procurement process to identify qualified contractors for both non-routine maintenance projects, such as comprehensive rehabilitation projects, as well as routine maintenance of SCMs. The City has also developed mechanisms that would hold contractors responsible for issues that develop during a period following the completion of maintenance work and before the device is accepted by the Stormwater Division. This will be accomplished by providing for a contracting mechanism that incentivizes the contractor to maintain the device until final acceptance. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan February 2022 AECOM 5-3 5.5 Notification of Immediate Corrective Actions The immediate need for corrective actions may be triggered when the inspection reveals that the condition of an SCM may be deemed hazardous to public health, safety, and welfare or if the SCM is no longer functional. Examples of hazardous conditions may include standing water on travel ways open to traffic, failed/crushed piping, missing manhole covers, signs of embankment failure, damaged fencing around steep slopes, flooding hazards, etc. If an SCM is discovered to be a danger to the health, safety, and welfare of the public, the inspector should immediately notify their point of contact at the City by phone of the hazardous conditions so that appropriate action can be taken to address the issue. A hotline number (919-996-3940) or an email to RaleighStormwater@raleighnc.gov can also be used as methods for reporting. A quantitative risk assessment scoring mechanism, which will assess the level of risk to the City if a stormwater device were to fail, is currently in development and will be applied to the annual inspection checklists for City-owned SCMs. 5.6 Documentation of Completed Maintenance and Costs The owning department is responsible for documenting completed maintenance and associated costs within the CityWorks application. The Stormwater Management Division will reimburse the owning departments for any maintenance costs as specified in the SLA. Costs are tracked on a per device basis for time, labor, and materials. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 6-1 6 Annual Program Review The Stormwater Management Division reviews its stormwater program annually in order to identify whether sufficient funding and resources are available to meet the City’s NPDES MS4 permit requirements. The following section discusses the Asset Management Program’s budget and resource needs, and how the City seeks to continually improve its stormwater program. 6.1 Identify Budget and Resource Needs The Stormwater Management Division reviews their budget and resource needs for the Asset Management Program to perform inspections and maintenance for all City-owned SCMs. Program duties typically include: • Prepare and update SLAs with City departments that own SCMs, as appropriate. • Accept SCMs into the program once they are constructed, as-built certification is completed, and warranty period has ended. • Confirm with SCM Inspections Program staff that all SCMs accepted into the program are classified correctly such that all devices are inspected routinely and annually, as required. • Identify maintenance needs and develop R&R Plans accordingly based on routine and annual inspections. During annual review, the SCM Inspections Program documents several reporting metrics associated with the City’s post-construction runoff MS4 requirements, such as the number of sites with SCMs throughout the City and the number of sites with newly approved O&M plans. The Stormwater Management Division can use these metrics to assess program growth and whether more funding and/or resources are needed going forward. As SCMs continue to be constructed throughout the City of Raleigh, the Stormwater Management Division will continue to annually assess the budgetary, staffing, and resource needs for performing the Program’s duties listed above. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 6-2 6.2 Adaptive Management The City aims to continually evaluate and improve the Asset Management Program through process improvements based on findings from the annual program review. The City can make appropriate changes to the different procedures used to accomplish the program goals, such as evaluating the annual inspection checklists for necessary improvements and tracking SCM LOS scores or other performance measures to identify SCMs that may need more frequent maintenance to maintain functionality. City of Raleigh Project Number: 60658668 Asset Management Program SCM O&M Plan March 2022 AECOM 7-1 7 Annual Reporting The Stormwater Management Division is required by the City’s NPDES MS4 permit to submit an annual report describing the activities performed in support of each aspect of its Stormwater Management Plan (SWMP). The annual report is divided into ten sections, which include the six minimum control measures, program implementation, water quality monitoring, and total maximum daily loads. Each section includes a brief program narrative, the specific MS4 permit requirements, and associated best management practices (BMPs), as identified in the SWMP. Each program-specific BMP is accompanied by an annual reporting metric specified in the SWMP in order to demonstrate compliance, followed by the activities performed by the City during the permit year. MS4 permit requirements relating to SCMs, annual reporting metrics, and activities performed during the permit year are recorded in Section F of the annual report.

To meet the stormwater quality standards of the permit, the City utilizes stormwater control measures (SCMs), which are permanent structural devices designed to manage stormwater runoff. For SCMs to work effectively, they must be inspected and maintained regularly. The City of Raleigh Stormwater Management Division maintains and tracks the compliance of more than 2,000 SCMs across the City. In order to execute its SCM program, the City of Raleigh implements two city programs: 1) the SCM Inspections Program, and 2) the Asset Management Program. The SCM Inspections Program is a team of City employees tasked with tracking the compliance of all SCMs and overseeing enforcement. The Asset Management Program is a team of City employees responsible for ensuring that all City-owned SCMs are inspected, maintained, and functioning as designed. 1.1 Purpose of Document The purpose of this SCM Inspection Standard Operating Procedure (SOP) is to provide standard procedures for SCM inspectors to conduct thorough inspections at each site, in order to ensure SCMs are performing properly in compliance with the site’s approved stormwater control plan and the City’s Unified Development Ordinance (UDO) Section 9.2.2.D. The recommendations and best practices detailed in this document are based on industry standards. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 2-1 2 SCM Inventory To ensure uniform tracking of all pertinent SCM information, the SCM Inspections Program maintains an internal spreadsheet called the “Tracking Spreadsheet”. The spreadsheet is used to track the annual inspection compliance status of each site, the anniversary date, plan name, site address, site contact information, and any tracking notes associated with each site. The spreadsheet is updated periodically to reflect any changes in ownership or contact information, compliance status, etc. To manage SCM data, the SCM Inspections Program creates and manages an N-file (N: Total Nitrogen) folder on the City’s server for each site, which may contain more than one SCM. An N- file folder contains digital copies or scans of a site’s as-built information, site maps, previous inspection documentation, enforcement documentation, and any other historical documents. The N-file folders assist the City with compliance tracking and fulfilling document requests from property owners and inspectors. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 3-1 3 Types of Inspections and Frequency The SCM Inspections Program administers inspections for SCMs required under the UDO Sections 9.2.2.A, B, or E. The following section describes the three types of SCM inspections. 3.1 Internal SCM Inspections At the direction of City Council, all SCMs within the City of Raleigh that were required under UDO Sections 9.2.2.A, B, or E must have an internal inspection be conducted by City Staff once every three years. The inspection report and accompanying photos are stored in the N-file folder, and the date of the most recent internal inspection is stored in the Tracking Spreadsheet mentioned in Section 2. These inspections are not required by the City’s National Pollutant Discharge Elimination System (NPDES) MS4 permit. 3.2 Routine SCM Inspections Routine inspections are not required by the City’s NPDES MS4 permit. However, since City- owned SCMs must be regularly maintained, the Asset Management Program conducts routine inspections of all City-owned SCMs on a quarterly basis. Any routine SCM inspections conducted on private property are completed at the discretion of the property owner. 3.3 Annual SCM Inspections Annual inspections are required for all SCMs that are under the City of Raleigh’s UDO Sections 9.2.2.A, B, or E. An annual inspection must be completed and certified by a North Carolina Professional Engineer, Surveyor, or Landscape Architect. The annual inspection report must certify that all SCMs, including open space areas, are performing properly and are in compliance with the approved stormwater control plan, the applicable maintenance manual, and Raleigh Stormwater Control & Watercourse Buffer Manual. Inspections are due on a yearly basis and must be conducted within 90 days prior to the SCM’s anniversary date. The anniversary date is based on the date the SCM as-built certification was accepted by the City. Pursuant to the owning department’s Service-Level Agreement (SLA), the Asset Management Program is responsible for annual inspections of City-owned SCMs. Therefore, the Asset Management Program contracts with professionals when necessary to perform these inspections and submit the reports to the SCM Inspections Program. Annual inspections are reviewed, enforced, and tracked by the SCM Inspections Program. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 4-1 4 Procedures for Inspection Preparation and Safety Proper preparation prior to SCM inspection is key to ensuring each inspection is thorough and representative of a device’s current condition. Prior to inspection, the inspector should review all relevant site documents, confirm that the inspection is scheduled appropriately, gather all necessary field equipment, and take adequate safety precautions. The following sections discuss the procedures for proper inspection preparation. 4.1 Document Review Reviewing historical documents prior to SCM inspection is an essential part of inspection preparation. The documents an inspector can reference and the information the inspector should take note of within each document are listed below. Digital copies or scans of historical documents are stored in each site’s N-file folder on the City’s server. As-Built Drawings & Photos: As-built drawings are construction drawings that show the post-construction dimensions, elevations, and locations of all design components associated with each SCM on site. Certified and sealed as-built drawings for each site must be submitted to the City upon completion of SCM construction. Inspectors should review the as-built drawings prior to inspection and take copies into the field if able. Prior to inspection, inspectors should review the as-built drawings and photos for the locations of all design components within the device, inlet and outlet pipe sizes and materials, riser details, vegetation, and any other pertinent information related to the device’s design. Once in the field, the inspector can then verify the as-built drawings against the device and note any deviations. Examples of deviations may include differing inlet pipe sizes or materials, the number of inlets in the field does not match the as-builts, riprap armoring on the emergency spillway was present in the field but not shown in the as-builts, etc. In case of SCMs where as-built documents are not available, available design drawings should be reviewed and any deviations noted in the inspection reports. Planting Plans: Planting plans are construction drawings that show the different varieties of plants that should be present within a device after construction is completed, as well as the number of each plant variety. Planting plans are often included with the as-built drawings and are typically only associated with devices that use planted vegetation for treatment such as stormwater wetlands, bioretention cells, and Filterra units. If a device has a planting plan, inspectors should review the planting plan prior to inspection and take a copy into the field if able. Prior to inspection, the inspector should become familiar with the plant varieties shown on the planting plan and gather information on what the plants look like so the inspector can identify them in the field. Once in the field, the inspector can then verify the planting plans against what is present in the device and note any deviations. Deviations may include different plant varieties present in the field than what is shown in the planting plan, and the specified number of each plant variety in the field does not match the planting plan. Stormwater Operation & Maintenance (O&M) Manual:All SCMs required under the UDO Sections 9.2.2.A, B, or E must have an approved O&M manual. O&M manuals are device-specific documents written by the design engineer that establish procedures and maintenance requirements for each design component. Inspectors should briefly SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 4-2 review the O&M manual prior to inspection to gather information such as the required drawdown time, vegetation that should be removed if present, appropriate grass height, where to inspect for signs of erosion, different kinds of erosion and the associated indicators to look for, specific areas of outlet structures that warrant close inspection, depth of sediment inside the device that requires removal, permanent pool elevation, etc. Previous Inspection Reports: Previous years’ inspection reports are particularly important to review prior to inspection. Inspectors should review the reports for information regarding previous routine maintenance needs and any major repairs identified. During inspection, the inspector should verify that all maintenance needs or repairs mentioned in the previous inspection report have been addressed. 4.2 Scheduling Inspections The inspector should take into account the type of inspection being performed, the SCM’s anniversary date, if any of the devices on-site are dependent on the growing season, recent rainfall amounts, and the proximity to other sites. More detail on what specifically the inspector should consider when scheduling an inspection is provided below. Inspection Type:There are three types of inspections performed by the City with different frequency requirements. The inspector should be aware of the inspection type they are performing and schedule accordingly. Refer to Section 3 for more information on each inspection type and their frequency. Anniversary Date:An SCM’s anniversary date is defined as the date the as-built package for an SCM requiring an annual inspection was accepted by the City. If the inspector is performing an annual inspection, the inspector must perform the inspection and submit the annual inspection report within 90 days prior to the anniversary date for the site to remain in compliance. Growing Season:Inspecting certain devices during the growing season is especially important for annual inspections. The main purpose of annual inspections is to confirm that the device is functioning as designed and is maintained properly. For device types that include planted vegetation as a design element, it is critical to inspect these devices during the growing season to ensure that the health of the planted vegetation can be accurately assessed. Devices that commonly include planted vegetation are stormwater wetlands, bioretention cells, and Filterra units. Significant Storm Events:A significant storm event is defined as a storm totaling greater than 1 inch within 24 hours. Unknowingly inspecting devices directly after a significant storm event could lead to conclusions that are not representative of the overall condition of a device. For example, unknowingly inspecting a dry pond the day after a significant storm event could cause the inspector to falsely conclude that the device is holding water, triggering maintenance items. Inspectors should consult a device’s O&M manual or the device-specific North Carolina Department of Environmental Quality (NCDEQ) O&M manual to determine the required drawdown time. Inspectors should also review recent rainfall data to determine if a significant storm event or any other smaller events have occurred within 72 hours of the inspection and take that data into consideration when performing an inspection. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 4-3 Location:If an inspector is performing inspections at multiple sites on a given day, the inspector should use each site’s location and determine their proximity to each other to determine the most efficient route. 4.3 Field Preparation Proper field preparation is an important aspect of conducting thorough inspections, and the necessary equipment and preparation may vary between sites. Some SCMs may be located at secure facilities or on private property and will require inspectors to notify and coordinate access with the City departments, the facility, and/or the owner prior to inspection. Depending on the device type, such as devices with underground components, inspectors may also need to coordinate with the City or subconsultants to facilitate the use of closed-circuit television (CCTV) devices prior to the inspection of underground components. Some sites will require facility and/or device specific preparation, and inspectors should develop a checklist of field items needed to complete inspections. This checklist should include items such as proper identification, inspection forms, electronic devices used for inspections, personal protective equipment (PPE), a first aid kit, sunscreen, insect repellant, snake chaps, measuring tape, leather gloves, manhole hooks, etc. An example field materials checklist can be found in Appendix A. 4.4 Safety Prior to performing field inspections, safety precautions should be taken as needed, including, but not limited to, conducting a vehicle check before traveling to the site, avoiding hazardous weather conditions, wearing the appropriate PPE, and taking frequent breaks for water. Inspectors should avoid confined spaces unless trained and equipped with the proper PPE and required certifications. Inspectors should be aware of their surroundings at all times while performing inspections. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 5-1 5 Inspection Checklists The City performs three types of SCM inspections: internal, routine, and annual. Each type of inspection uses a distinct inspection checklist. The following sections provide an overview of the checklists for each type of inspection with guidance on how to complete them. The figures shown in Sections 5.1 and 5.2 use the Dry Detention inspection checklist as an example. 5.1 Internal Inspections At the direction of City Council, all SCMs within the City of Raleigh that require an annual inspection must be inspected once every three years by City staff. Internal inspections are performed by the SCM Inspections Program using PDF-fillable, device-specific inspection checklists called Form 600s. A blank Form 600 is attached in Appendix B. Each inspection checklist, regardless of device type, requires the inspector to fill out general information about the site. This information, shown in Figure 1 below, is important to ensure each device being inspected is accurately identified. Figure 5-1: Internal Inspections Checklist – General Information The inspection checklist is intended to be brief but provides each design component and the overall device with a status of Fully Functional (FF), Minor Functional Issues (MFI), Partially Functional (PF), or Not Functional (NF). Once finished with the inspection, the inspector should assign the device an Overall Status of FF, MFI, PF, or NF based on the assessment of each design component. The status codes are defined as follows: Fully Functional (FF) – All parts are in good working order Minor Functional Issues (MFI) – Device is functional, but has some minor areas to monitor Partially Functional (PF) – Part of the device needs repairs Not Functional (NF) – Repairs are required Each design component has a series of checkboxes that list potential maintenance needs associated with that design component. Common maintenance needs may vary slightly across design components. During inspection, the inspector should only check the boxes that apply. Figure 5-2 below is an example of how this may be filled out in the field. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 5-2 Figure 5-2: Internal Inspections Checklist – Maintenance Needs Assessment Once the inspector has checked all boxes that apply, each design component will be assigned a status code based on what was observed in the field. For further clarification, any field observations or maintenance needs should be written out in the Comments section for each design component. The comment shown in Figure 5-3 below illustrates how to fill out this section. Figure 5-3: Internal Inspections Checklist – Status Code At the end of each inspection checklist is an area for the inspector to attach photos, shown below in Figure 5-4. The inspector should attach photos of any important maintenance needs identified during the inspection and include a caption explaining what is being shown in each photo. Figure 5-4: Internal Inspection Checklists – Photos of Maintenance Needs SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 5-3 5.2 Routine SCM Inspections Routine SCM inspections of City-owned SCMs are performed quarterly by the Asset Management Program using electronic inspection checklists developed in CityWorks. Privately- owned SCMs are inspected at the discretion of the property owner and do not use the routine inspection checklists shown in Appendix C. Appendix C includes an overview of the routine SCM inspection fields as they appear in CityWorks. Routine inspections checklists are brief in nature and are specific to each device type. The inspector is required to select Yes or No from a drop-down menu in response to each question, shown in Figure 5-5 below. Figure 5-5: Routine Inspections Checklists – Drop Down Menu Maintenance needs are identified throughout the routine inspection checklists based on the question and the inspector’s answer. Contingent on an inspector’s answer, the inspector may be required to provide comments, as shown in Figure 5-6; however, certain questions require a comment regardless of the inspector’s answer, as shown in Figure 5-7 below. Comments should clearly explain the current condition of the design component in question, the routine or immediate maintenance needs identified, and any other information needed to understand the device’s current condition. Figure 5-6: Routine Inspection Checklists – Comments Contingent Upon Previous Answer Figure 5-7: Routine Inspection Checklists – Required Comments SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 5-4 Lastly, at the end of each inspection checklist is an area for the inspector to provide any closing observations about the overall device, list all needed repairs across all design components, and provide recommendations for maintaining the device. The inspected SCM is then assigned a condition score. The conclusion of the routine inspection form is shown below in Figure 5-8. Figure 5-8: Routine Inspection Checklists – Closing Observations 5.3 Annual SCM Inspections Annual inspections are performed on a yearly basis and must be conducted within 90 days prior to the SCM’s anniversary date. Annual inspections of City-owned SCMs are conducted by the Asset Management Program or their contracted professionals. Annual inspections of privately- owned SCMs are conducted by a North Carolina Professional Engineer, Surveyor, or Landscape Architect as discussed previously in Section 3.3. Annual inspections require thorough evaluation of each design component to demonstrate that the device is functioning as designed. The Asset Management Program has developed nine device-specific annual inspection checklists for inspection of City-owned SCMs. Checklists were developed for the following SCM types:  Bioretention basin  Dry pond  Filterra  Level spreader  Sand filter  Stormwater wetland  Swale  Underground detention  Wet pond A generic annual inspection checklist was also developed to be used for any device that does not have a specific checklist. Appendix D includes the nine (9) SCM-specific annual inspection SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 5-5 checklists as well as the generic SCM inspection checklist. Appendix E includes an example annual inspection checklist, which has been annotated with instructions and guidance on how to complete.Not all sections of the annotated inspection checklist have been completed, but rather only the sections where guidance on completing the checklist would be beneficial to the inspector. Each inspection checklist contains a General section that documents relevant site information such as the device type, N-file, date of inspection, the site’s anniversary date, recent rainfall, etc. The following sections of each form are specific to the design components associated with each device type. For example, the dry pond inspection checklist will include sections for Inlet Points, Forebay, Basin, Outlet Structure, Emergency Spillway, Embankment, and Miscellaneous, whereas the swale inspection checklist will include sections for Inlet Points, Swale, Outlet Structure, and Miscellaneous. Each design component section asks a series of questions to determine if the component is functioning properly or needs maintenance. Each question requires a two-part answer. The inspector will be required to provide an Observation of Yes,No, or Not Applicable and an Action of Monitor, Investigate,or Repair.Once the inspector has completed all questions, the inspector will be required to give each design component a Status Code of Fully Functional (FF),Partially Functional (PF), or Not Functional (NF) and provide notes detailing what was observed in the field to warrant the Status Code assigned. At the conclusion of each annual inspection checklist are the Approximate Quantity of Maintenance Items Required section and the SCM Evaluation section. If applicable, the inspector shall document the length, material, and diameter of pipe replacement, as well as the square footage of area to be re-seeded and the number of trees to be removed in the Approximate Quantity of Maintenance Items Required section. The SCM Evaluation section requires the inspector to provide a summary of all routine maintenance needs and immediate corrective actions, the probability and consequence of failure, and providing a Level of Service score for the overall device. The Level of Service score for each device is used by the City to track the performance of SCMs over time. The details on Level of Service scores are provided in the checklists in Appendix D. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 6-1 6 Documentation of Completed Inspections Documentation of completed annual SCM inspections are required by the City’s MS4 NPDES permit to be in compliance. Internal and routine SCM inspections are documented for the City’s record but are not required by the City’s permit. Completed Internal SCM Inspections:Internal inspections are tracked in the City’s Tracking Spreadsheet managed by the SCM Inspections Program. The date of inspection and any observations or maintenance needs identified during the inspection are also documented in the City’s Tracking Spreadsheet. Completed Routine SCM Inspections:Routine inspections of City-owned SCMs are completed and tracked in CityWorks by the Asset Management Program. Completed Annual SCM Inspections:Annual inspection reports for SCMs are submitted to the SCM Inspections Program up to 90 days prior to the SCM’s anniversary date in PDF format and are tracked using the City’s Tracking Spreadsheet. All annual inspection reports of SCMs required under the UDO Sections 9.2.2.A, B, or E are retained for 6 years and are located on the City’s server. Annual inspection reports of SCMs are required by the City to be submitted with a Stormwater Device Annual Inspection Summary form (Form 501). Form 501 serves as a cover page for the annual inspection report and provides a general overview of the SCM location, property owner information, and the North Carolina Professional Engineer’s, Surveyor’s, or Landscape Architect’s seal. As specified in Form 501, reports should include all items listed in the Stormwater Device Annual Inspection Report Checklist. SCM Inspections SOP Project Number: 60658668 January 2022 AECOM 7-1 7 Compliance and Enforcement Processes Compliance and enforcement procedures only apply to annual inspections. The submittal of an annual inspection report within 90 days prior to a device’s anniversary date is required for all SCMs to remain in compliance with UDO Sections 9.2.2.A, B, or E.
