Low Impact Development

We are passionate about the wonderful place we live in and through our work strive to improve our environment. DCG's engineers are well-versed in Low Impact Development (LID) with training and certification through the LID program offered by the Puget Sound Partnership and WSU Department of Civil Engineering, as well as experience in numerous LID projects.

Whidbey Island Center for the Arts (WICA) - Whidbey Island, Washington

Whidbey Island Center for the Arts Davido Consulting Group provided civil and structural services for the expansion of the existing WICA Theater which is seeking LEED Certification. DCG has designed stormwater controls, such as rain gardens and drywells, using Low Impact Development techniques, and is completing the LEED submittal paperwork for the water quality control credits and the construction stormwater pollution prevention (TESC) credits.

Seattle Pacific University Camp Casey - Whidbey Island, Washington

Davido Consulting Group provided engineering planning services to Seattle Pacific University for the Camp Casey Conference Center Master Plan. This plan provides for the phased development of facilities at Camp Casey to meet the need for a modern conference center that will likely strive for LEED and/or other environmental certifications. DCG provided stormwater planning with LID BMPs including rain gardens for treatment and infiltration.

The Highlands - Langley, Washington

The Highlands DCG was contracted to provide site civil engineering design services for a 52-unit mixed residential use community on a 14-acre site in Langley, Washington. Design services included storm water controls utilizing low impact techniques including raingardens and downspout drywells.

St. Augustine’s In-the-Woods Site Improvements - Washington

DCG was contracted by the St. Augustine In-The-Woods Episcopal Church to provide site design services for renovations to their existing church facility and parking lot. DCG utilized Low Impact Development stormwater design techniques including bioretention (rain garden) facilities and stormwater dispersion systems to control stromwater runoff from the site.

The goal of the low impact design techniques was to mimic predevelopment conditions by increasing time of concentration for storm events using a combination of infiltration and dispersion to limit surface runoff from impervious surfaces. Amended soils and landscaping within the proposed rain gardens provides water quality treatment, as well as, an increase in plant evapotranspiration potential. Excess stormwater from the rain gardens is directed through a Department of Ecology approved dispersion system to existing buffer perimeter vegetation similar to pre-project conditions.

Kinney Street Parking Lot Improvements - Island County, Washington

Kinney Street Parking Lot improvements Kinney Street Parking Lot Improvements, Island County: DCG was contracted to provide site design services for the renovation of an existing service vehicle parking facility in the town of Coupeville, Washington.

Design work included the incorporation of LID stormwater control techniques such as bioretention (rain garden) areas and permeable paving, in the form of a plastic grid system, to help attenuate peak surface water runoff.
