Koon’s Toyota working with Spa Creek Conservancy pro bono ESDS consultants and members of SCC, to develop the site BMP requirements. The ESDS representatives are long standing members of Spa Creek Conservancy and provide pro bono services on project technical services and project management. The project was managed and technically directed by the ESDS alliance, in coordination with the technically qualified City staff.
SCC partnered with the Koon’s Toyota to meet the following objectives:
• Reduction of site stormwater runoff by 40 percent (CBP goal) from area of over 98% imperviousness through infiltration and filtration.
• Introduce and demonstrate a new stormwater runoff reduction BMP and sheet flow control techniques by using cisterns.
• Continue the successful Spa Creek Stewards Program developed with Center for Watershed Protection with CBT funding in 2009.
• Provide a “to do” list of BMP for implementation at the site. Many of the recommendations can be implemented by procedural changes, e.g. dumpster cleanliness, and alertness to critical pollution issues, e.g., car leaking fluids, and car washing practices.
• Provide a multi-business showcase project for the automobile dealership and general business communities of Annapolis – Baltimore – Washington.
• Mitigate the pollutant and nutrient loads of the runoff from 38% to 87% (see research). Remove 90+% of Total Suspended Solids – Site contributes to both College and Spa Creeks.
• Install interpretive signage on West Street for maximum exposure to Annapolitans and visitors.
This is the first breakthrough initiative Spa Creek Stewards Program project. Getting businesses in these very tight economic times to consider their environmental impact on their local watersheds represents a major challenge. They recognize that they may have severe pollution problems but they have little knowledge of how their runoff affects the creeks. Culprits like sealants that protect parking lots are cancer causing agents according to a study that appeared in Environmental Science & Technology, and the journal of the American Chemical Society.
Besides car emissions, it turns out automobiles are indirectly causing yet another environmental problem: parking lot pollution. Researchers at Purdue University have shown they contribute significantly to water pollution. Parking lots accumulate pollutants such as oil and heavy metals that cannot be absorbed by their surfaces; the pollutants are then washed into creeks by way of rainfall. This type of runoff is very toxic to our tributary biosystems and fisheries.
This project design was developed by the experienced engineers and landscape architects. The Spa Creek Conservancy project team with the pro bono assistance of Anne Guillette, MLA, LEED AP, of LID Studio, who is a member of SCC, was invited to coordinate on the best management practices design and location.
