Stormwater Retrofit & Low-Impact Development (LID) Project Team Deliverables
- Site Information – Kittery Traffic Circle Project (3,328Kb PDF)
Stormwater runoff is one of the largest water quality concerns in Spruce Creek. There are two primary problems associated with stormwater runoff: the increase volume and rate of runoff from impervious (paved) surfaces, and the concentration of pollutants in the runoff. In order to address stormwater runoff issues in the Spruce Creek Watershed, the Project will implement LID techniques at specific sites.
LID is an approach to environmentally friendly land use planning. It includes a suite of landscaping and design techniques that attempt to maintain the natural, pre-developed ability of a site to manage rainfall. LID techniques capture water on site, filter it through vegetation, and let it soak into the ground where it can recharge the local water table (groundwater) rather than being lost as surface runoff. An important LID principle includes the idea that stormwater is not merely a waste product to be disposed of, but rather that rainwater is a resource. The LID approach protects the natural ability of the site to capture precipitation, keep it clean and allow it to recharge the local water table.
At a small scale, LID techniques can be used to better handle rainfall for a single family lot through rain barrels and rain gardens. At a larger scale, proper site design in combination with many landscaping and infiltration techniques distributed throughout a development, cumulatively improve rainfall and run off management.
The LID Project Team will implement two large-scale and two smaller-scale stormwater retrofit LID demonstration projects. One of the large-scale sites is the parking lot at Bob’s Clam Hut. The Project Team will work with the owner and plant manager to provide consulting and design services to ensure their already-planned parking lot improvements maximize stormwater control. The three other projects will also be located either at the Town Hall or in the commercial “outlets” area, and will include two smaller sites (for example a curb-cut to a tree well) and a larger site (one which handles a larger area of stormwater runoff, such as a planted parking lot median).
Because the focus of this whole project is not only the reduction of stormwater impacts, but also the ability to educate others about methods of control, it will be important to develop these “showcase” sites where town boards and officials can demonstrate innovative stormwater control methods and show these best management practices in use. Final site selection will be determined on the basis of technical feasibility, cost-effectiveness, opportunity for demonstration to other commercial and municipal entities, and feasibility of maintenance. Site designs will be sent to Maine DEP for review and approval. Site selection will be completed in year one and installation will be complete within two years.
Grant Funding $24,635
Total Cost $72,275
Grant funding includes approximately 140 hours from the grant manager and 100 hours of a technical advisor from York County Soil & Water conservation District (YCSWCD). Additional funding has been included for travel expenses for these two project staff as well as $500 for supplies. There will also be $5,000 for an engineering consultant and $10,000 for construction. There is the potential for some of these funds to be shared across other projects under the grant as well. The matching funds include businesses, volunteers, and Town employee’s time and travel expenses for this work, as well as $1,000 in-kind from the Town for use of the GIS system. Additionally, the Town will match the construction monies with $20,000 and the retailers will match $17,000. There is also $400 for supplies as in-kind match.
- Reviewing existing Route 1 Stormwater Survey (and its authors) to identify sites
- Working with SCA to identify sites Working with TOK to identify municipal sites
- Working with retail outlet and restaurant owners and the Maine DOT to determine the final locations for stormwater retrofit implementation based on current efforts with the Kittery Premium Outlets future capital improvement efforts on private property, roadway maintenance activities and/or municipal planning efforts.
- Working with stormwater and LID specialist(s) who will develop the best stormwater Best Management Practice (BMP) technologies to utilize in the selected retrofit locations.
- Implementing at least two stormwater retrofit demonstration areas that will provide significant treatment of stormwater quantity and quality.
- Cooperating with the nearby UNH Stormwater Center to develop the best technology for the sites and use extensive data to determine probable benefits.
- Developing Letters of Agreement outlining long-term maintenance and construction cost sharing of the BMPs to be signed by all property owners before construction commences. Example letters will be provided by DEP.
- Working with landowners and LID specialists to include innovative LID and stormwater retrofit techniques at two identified retrofit sites within the retail district.
- Determining project opportunity by looking at possible financial partnering through capital improvements or other municipal or state activity and likely water quality benefits.
- Working with landowners to construct two smaller-scale LID technologies for demonstration of water quality improvements.
- Obtaining, if necessary, environmental permits before construction.
- Ensuring NPS Program grant funds are not used to undertake, complete or maintain erosion or storm water control work otherwise required by existing permits or orders.
- Working with Grant Manager to produce NPS Site Report for each NPS site.
