"Owner Will Maintain" program in King County

"Owner Will Maintain" Program

King County offers residents the opportunity to participate in a companion program to the Roads Maintenance Spray Program. The "Owner Will Maintain Program" allows residents to control vegetation on the right-of-way that abuts their property. To participate in this program, residents must sign a maintenance agreement with the county to maintain the right-of-way and to also post "Owner Will Maintain" signs in an area visible from the roadway.

Maintenance agreements may be obtained using the "No Spray Request Form" or by calling 206-477-8100 or toll-free by calling 1-800-KC-ROADS. The maintenance agreement must be completed and returned to Road Services before an "Owner Will Maintain" sign can be issued. The signs are provided to property owners at no charge. To continue participation in this program, residents must complete a new agreement and submit it to Road Services annually.

"Inert" Ingredients the EPA has now removed from the approved list

In December 2016, the Environmental Protection Agency (EPA) announced they would take action to remove 72 ingredients from their approved pesticide products list. According to the EPA, “Manufacturers wishing to use these ingredients in the future will have to provide EPA with studies or information to demonstrate their safety. EPA will then consider whether to allow their use.”

Fact Sheets on Common Garden Problems

Fact Sheets on the top garden problems, and their least toxic solutions, were created in 2015 through the combined efforts of the EPA,  Puget Sound Partnership, and Seattle Tilth, with input from our Garden Green effort.   Each Fact Sheet covers the these common problems:

•          Aphids

•          Dandelions and other broadleaf weeds

•          Moss

•          Powdery Mildew and other fungal diseases

•          Quack grass

•          Slugs and Snails

The Fact Sheets were customized by Garden Green to include all the products sold on Vashon Island which are rated Green in all categories by Grow Smart, Grow Safe®, (GSGS): 1. human health, 2. pets and wildlife, 3. aquatic life, and 4. water pollution.   Click here for the complete set of Fact Sheets customized for Vashon Island

Pesticide Induced Disease Database

The common diseases affecting the public’s health are all too well-known in the 21st century: asthma, autism and learning disabilities, birth defects and reproductive dysfunction, diabetes, Parkinson’s and Alzheimer’s diseases, and several types of cancer. Their connection to pesticide exposure continues to strengthen despite efforts to restrict individual chemical exposure, or mitigate chemical risks, using risk assessment-based policy.
