To support long term growth planning and development of the island, the City of Bainbridge Island (COBI) needed to collect physical and groundwater data for a groundwater model that would set the stage for urban planning efforts. COBI also required improved tracking of Illicit Discharge and Detection (IDDE) to meet a tight grant-funding deadline and be in compliance with its Phase II National Pollution Discharge and Elimination System (NPDES) permit.
To meet data collection and management goals for the groundwater model, Aspect developed a custom database to collect field and electronic data in a single repository that allows holistic review, analysis, and reporting. COBI completed the hand off of all the required data to US Geological Survey for their modeling pursuits, as well as setting a new bar in reporting to citizens. To meet COBI’s NPDES requirements and the grant funding deadline, Aspect developed a custom database to track all of their cases digitally, allowing the city to quickly and accurately calculate the annual statistics required for government reporting. COBI met the funding deadline now has the tools necessary to report on the cost, effort, quantity, and types of Illicit Discharges that occur on the island at any time.
Port of Seattle Stormwater Services
Aspect has assisted the Port of Seattle in complying with mapping, SWPPP, O&M, best management practices, and records-keeping requirements of their Phase I Municipal NPDES Permit.
Our work has included the following:
- Developing and maintaining a geodatabase mapping the stormwater conveyance system for all Seaport facilities. Coordinated initial mapping of stormwater system. Updated GIS system as new information is learned or system is modified by construction.
- Coordinating development of a web mapping application to share stormwater mapping data within the Port.
- Custom database application development to track Port leases to determine relevance to stormwater management.
- Planning and design of a temporary stormwater collection and treatment system.
- Participating in development of Operation and Maintenance Manual for stormwater system. Updated O&M manual to include new City of Seattle requirements in 2010.
- Developing and maintaining a stormwater records keeping data base.
- Developing SWPPPs for all Seaport operated facilities. Developed SWPPP template for use by Port tenants. Assisted a few port tenants in completing SWPPP template.
- Overhauling recreational and commercial vessel BMPs.
- Managed laboratory and field water quality monitoring data and submitted final data to Ecology’s database EIM.
- Conducting a planning exercise for Industrial Stormwater General Permit.
- Assisting with outfall inspections.
