Low Impact Development (LID) 

Here are some links to examples, how-to's and other helpful info and guidance. Some links may include information about programs that are available only to persons living in that community:

Directions and list of nearby LID uses that are accessible to the public:


Fort Nugent Park, Oak Harbor Parks & Rec, Fort Nugent Rd: 100% on-site

stormwater retention using bioswales, ponds with native plants,

& (due late 2007) a pervious concrete pathway to football field & beneath bleachers.

Harbor Station, mixed use commercial development, corner NE 7th & SR 20 (due in 2008):

Runoff directed into planted bioretention strips with under-drains, filters through plants &

topsoil,then into perforated pipe to underground retention area. On-site subsoils infiltrate

poorly,so stormwater must be piped off site, but LID systems will clean water & regulate



Coupeville High School, south of SR 20 at intersection of SE Main & Terry (new in 2007):

Water from paved areas flows through bioswales into vegetated detention pond. Property

is atop impermeable clay so on-site infiltration to groundwater not possible, but pond

provides irrigation, wildlife habitat, education & surge protection as stormwater runoff is

slowed, filtered & cleaned by plants and soil. Excess runoff is piped from pond into storm

drain system.


Bayview Corner Redevelopment, a project of Goosefoot; at corner of Bayview Rd &

Marshview, just off SR 525: Showcases multiple LID features, including porous concrete

parking areas & sidewalks; interlocking plastic grid (grass pave) parking area; walkway

using interplanted recycled concrete pavers; composting toilet (public restroom) with solar

power & rainwater collection for flushing; & reused building materials. Call or e-mail to

arrange personal tour: 360-321-4535, info@goosefoot.org.

Bayview High School: Rain garden & native plant restoration in historic schoolyard

captures roof runoff. Call South Whidbey School District for visitation info: 360-321-2343.

Clinton Beach, Port District of South Whidbey Island, adjacent to ferry landing: Vegetated

roof on picnic shelter; porous surfaces & native landscaping for stormwater infiltration.
