Rain Garden Professional List

The link above provides lists of landscape professionals that attended training on rain garden design, installation, and maintenance. The lists are sorted by the location of the counties where the training took place. Some of the contractors provide services in counties other than where they took their training. This information can be found on each list. These lists are provided as a resource for homeowners seeking professional assistance with rain gardens.

Rain Gardens Work in Snohomish County

Snohomish County supports nearly 700,000 residents and continues to grow on a fast track. As we have lost native forests and replaced them with solid surfaces and stormwater sewers, water infiltration has decreased while surface water runoff has increased. The runoff has increased the severity of flooding and swept containments from our homes and streets directly into streams. Rain gardens give us the ability to mimic nature by increasing infiltration of stormwater that comes off our roofs, driveways and landscapes. This helps protect Puget Sound.

What is a rain garden?

Rain Gardens are simply shallow depressions that:

  • Can be shaped and sized to fit your yard
  • Are constructed with soil mixes that allow water to soak in rapidly and support healthy plant growth
  • Can be landscaped with a variety of plants to fit the surroundings

See the Rain Garden video.

Low Impact Development

Rain gardens are one of the most versatile and effective tools in a new approach to managing stormwater called Low Impact Development (LID). A LID project may incorporate several tools to soak up rain water, reduce stormwater runoff, and filter pollutants. Examples of these tools are permeable paving, compost-amended soils, vegetated roofs, rain water collection systems, and rain gardens.

Snohomish County Surface Water Management

The Surface Water Management Division provides a comprehensive approach to managing surface water in order to respect and preserve the county's streams, lakes and other waterbodies. Its main activities are to 1) protect water quality; 2) control, accommodate and discharge storm runoff; 3) provide for groundwater recharge; 4) control sediment and stabilize streamside and lakeshore erosion; 5) monitor water quality and quantity; and 6) rehabilitate stream and drainage corridors for hydraulics, aesthetics, and fisheries benefits. The Division provides technical advice to landowners in unincorporated areas of Snohomish County on a variety of issues and topics related to managing surface water on-site, including rain gardens, and managing streamside and shoreline properties.

Adopt-A-Stream Foundation Logo

Adopt-A-Stream Foundation

The mission of the Adopt A Stream Foundation (AASF) is to teach people how to become stewards of their watersheds. That mission is carried out by producing environmental education materials, conducting Streamkeeper Academy™ classes for all ages, and providing local communities with stream and wetland restoration technical assistance. Currently, AASF ecologists and technicians are surveying local streams to identify fish and wildlife habitat degradation and water pollution problems, designing solutions, and working with land owners to find resources for corrective actions that have included installing native plant landscapes in place of lawns, restoring wetlands from parking lots, stabilizing stream banks using “bio-engineered” techniques, building fish ladders, and creating new in-stream fish habitat.
