Sustainable Development Task Force's Technical Advisory Group on
Critical Area Ordinance Issues
The purpose of this technical advisory committee is to develop some suggested approaches and ideas for jurisdictions to follow in order to incorporate sustainable development strategies and principles into the update of their local Critical Areas Ordinances (CAO’s).
As we have discussed in our meetings, the challenge of offering technical suggestions to jurisdictions is that our advice must be easy to follow and flexible enough for incorporation. To this end, we have identified three (3) main areas of focus:
- Programmatic strategies for preserving shallow groundwater recharge functions
- Incentives for incorporating sustainable development strategies
- Incorporating the use of pervious concrete in new development, where applicable
These areas of focus provide a range of ideas, from an overall site and program assessment for determining the potential for incorporating sustainable development methods, to a rewards system approach, and finally to a specific technique that has test-case examples that can be identified. These issues are addressed in detail in the following attachment.
Technical Paper on Incorporating
Sustainable Development Methods into Critical Areas Ordinances

Barry
and Shahnaz Bettinger, owners of Snoqualmie Gourmet Ice Cream Company,
have a vision for their new facility in the Maltby area: a building
and development that have a low impact on the site, allows less
storm water runoff, uses less energy and water, produces less waste,
and provides a pleasant environment for customers. . Peter Anderson,
Imago De Lineo Architecture turned this vision into reality that
integrates site, building and community.The Bettingers have been
inspired by the expertise and energy of Noel Higa, Higa-Burkholder:
Land Use Planners and Civil Engineers, to see a sustainable development
through from start to finish
The
Snoqualmie Gourmet Ice Cream Company submitted a Low Impact Development
Project and was accepted into Snohomish County’s Reduced Discharge
Drainage Program. The site features an integrated low impact trail
system that will serve the Maltby Community. The plan allows for
a bio-filtration swale within the public right of way in lieu of
the standard curb gutter sidewalk approach found in most urban areas.
It sets the tone for continued environmental protection within Maltby
Urban Growth Area (UGA), especially since this is the headwaters
of several distinct drainage systems. “The people of Snohomish
County PDS have been great” said Barry, “Though this
project does not fit within their normal process they have been
very supportive”.
Other
innovative site features include:
-
Planned use of permeable pavers and concrete.
-
Tree retention and landscape plan that serves dual purposes of
reducing runoff as well as screening traffic noise and impacts.
-
Driveway widths will be reduced and the parking area will remain
in an unpaved condition.
-
A rain garden will also be incorporated into the site design as
part of the landscape and drainage features.
How about the building itself? State of the art energy efficient lighting, refrigeration and compressors along with heat recovery systems will significantly reduce energy and water usage. Snohomish County Solid Waste has worked with the Bettingers on a plan to reduce waste through recycling and other measures.
The Taskforce is proud to be working with such committed people as the Bettingers. Learn more about their ice cream and their innovative sustainable development at www.snoqicecream.com

The
Serene Way Sidewalk project
The Serene Way Sidewalk project was initiated by the Lake
Serene Community Association with a request for a walkway along
Serene Way from Shelby Road to Lake Road. This project is located
in a highly urbanized area in the southwest region of Snohomish
County
The
proposed walkway is approximately 4500 feet along Serene Way adjacent
to Lake Serene. Serene Way is a local access road and consists of
two travel lanes with little or minimal shoulders. Drainage from
the road collects into the open ditches along both sides of the
road. Existing right-of-way for the road is 60 feet.
