Stormwater Series: Newport News, Virginia
Operation and maintenance includes day-to day operation of AIMS (Analysis, Inspection, Maintenance, Support), back- and side-ditch maintenance, major outfall and lake maintenance, storm sewer cleaning, storm sewer construction, and roadside ditch maintenance throughout the city. The Vector Control section utilizes the concept of Integrated Pest Management (IPM), which includes surveillance for larvae and adult mosquitoes, establishment of action thresholds, selection of appropriate control strategies, and use of current technology.
In June 2004, the Asset Management Division implemented Cityworks, a GIS-centric asset management solution, for the Department of Public Works. The stormwater assets are in the GIS and therefore available in Cityworks. Over the past eleven years, Asset Management has worked closely with Stormwater to ensure their needs have been met by the GIS and Cityworks. Over time, stormwater assets have continually been captured and updated in the GIS. Updates to the GIS generally come from three sources:
Stormwater employees working collaboratively with GIS staff in the Asset Management Division to add assets and keep them up-to-date.
Completing projects to capture stormwater assets not already included in the GIS.
Surveyors from the Department of Engineering collecting data for integration into the GIS
To support asset management, attributes are populated as assets are added or updated in the GIS, allowing Cityworks users to view the assets and their characteristics. Information such as install date, material, condition, and condition date are critical. Service requests and work orders are used to capture operations and maintenance and vector control activities, as well as special project work. A complete work history is attached to each asset and can be used to determine its current and expected future performance. Additional GIS layers such as stormwater work management sub-areas and vector control areas are useful resources for Cityworks users. Layers such as these are used to help plan operations, maintenance activities, and projects.
GIS and Cityworks are also important tools for meeting regulatory standards. Depending on the type of service request or work order, the appropriate information required for regulatory compliance is captured. Using the collected data, stormwater management is able to report the division’s activities, thus ensuring compliance. This includes anything from the frequency of cleaning assets to the volume of debris removed. Currently, the Municipal Separate Storm Sewer System (MS4) Permit requirements are being finalized between the regulatory agency and the City. Asset management staff will then work with stormwater staff to review the requirements and determine if any changes are needed to the data captured in Cityworks. Changes could be anything from creating new custom fields to designing a new work order template. This open collaboration and commitment are vital to the success of the City’s stormwater program.
