Tree Canopy

Tree cover is important for cities because it reduces air, water, and noise pollution, and keeps our hard surfaces cooler, making cities more comfortable and reducing air-conditioning needs. City codes regulating tree removal and replacement in Shoreline are currently achieving the stated purpose of “no net loss.”

King County Planting 1 Million Trees

King County is working with Shoreline and other civic, public, and private partners to plant 1 million trees by 2020. By building on existing tree-planting efforts by Shoreline and others, this initiative amplifies those efforts to support common goals of cleaner air and water, more resilient landscapes and livable communities, and a smaller carbon footprint for the region.

Aurora Corridor Tree Plantings

As a part of the Aurora Corridor project, the City planted more than 900 trees in the medians and planting strips to increase Shoreline’s urban tree canopy, replenish oxygen, filter pollutants, provide shading to cool urban heat islands, and add natural beauty to the urban landscape. Tree grates surround street trees in the planting strip, which extend the walkable area of the sidewalk.


Shoreline’s resilience depends on supporting the health and wellbeing of all our residents. Access to parks is one indication of our community’s wellbeing. Open and natural spaces provide residents with opportunities for recreation and fitness, learning about the natural world, and improving emotional health.

Habitat Restoration

Development and non-native species have disturbed many sensitive natural areas. By restoring these critical areas in its parks, Shoreline can improve the overall health of natural ecosystems for wildlife. Dedicated volunteers help the City remove invasive species and secure funds and materials to replant native species in the critical areas in our parks.

Tackling Invasive Species in Partnership with EarthCorps

Shoreline has an active volunteer community. Many volunteers devote time to restoring habitat in City parks. Native Plant Stewards are active at Richmond Beach Saltwater Park, Hillwood Park, Twin Ponds Park, and South Woods Park. The City also works closely with nonprofit agencies such as EarthCorps and the Mountains to Sound Greenway Trust to hold volunteer events that create and restore wetlands in Shoreline’s parks.

Water Quality

The quality of our surface water, including lakes and rivers, affects the health of fish and wildlife habitat, safety of swimming beaches, and overall health of Lake Washington and Puget Sound. Conventional “gray” infrastructure allows polluted runoff to flow straight to these waterbodies, causing significant pollution. Shoreline aims to use green infrastructure, including pervious paving and natural drainage systems, to slow, absorb, and filter polluted runoff from roads and surfaces, returning cleaner water to our nearby streams, lakes, and Puget Sound.

Water quality has improved in many of Shoreline's streams since 2008. City strives to achieve water quality index score of 80 or better for all streams by 2030.

Water Quality Index

To measure the relative health of a stream over time, the City uses the Washington Department of Ecology’s Water Quality Index (WQI) score. The WQI summarizes water quality data in a simple, clear format. The score and ratings represent the relative water quality of the study streams over time.

Rebates for Rain Gardens in Soak-It-Up Program

Recognizing the importance of managing polluted runoff, Shoreline’s Surface Water Utility offers up to $2,000 rebates for home or business owners to install a rain garden or native vegetation landscaping on their property. These green features filter pollution before it reaches local waterways, reduce flooding by absorbing water, increase recharge of our groundwater resources, and provide habitat for insects and birds. Learn more about the Soak-it-up Rebate Program.

Salmon-Safe Certification

In 2019, the City of Shoreline was recognized as the first Salmon-Safe Certified City in Washington State. Salmon-Safe Certification recognizes Shoreline’s regional leadership in preventing water pollution and improving the health of the Puget Sound. Learn more about Salmon-Safe and access tips on how you can be Salmon-Safe and protect water quality at home and work 


Restore our natural areas

Girl Scouts removing invasive ivyJoin your neighbors for a fun and productive day of natural area restoration! The City organizes restoration work parties throughout the year where you and other volunteers can help remove invasive plants, plant native species, and beautify the landscape. Visit the calendar on the City website for information about upcoming habitat restoration parties and projects.

Install a rain garden

A rain garden is a planted, shallow depression that acts as a natural filter, slowing and cleaning runoff from roof tops, driveways, patios, and other areas that don’t allow water to soak in. Rain gardens can be shaped and sized to fit your yard, and can be landscaped with a variety of native plants to fit the surroundings. The City of Shoreline Surface Water Utility provides rebates of up to $2,000 for property owners in Shoreline to install a rain garden on their property. Visit the Soak It Up Rebate Program page to learn more. 

Install native vegetation landscaping

Native vegetation landscaping is the removal of hard surfaces such as pavement or turf grass and replacing it with native plant species that have deeper root systems and amended soils. In addition to laying down mulch, this technique slows down the flow of stormwater runoff, allows for the groundwater to recharge, and filters out pollutants. The City of Shoreline Surface Water Utility provides rebates of up to $2,000 for native vegetation landscaping projects. Visit the Soak It Up Rebate Program page to learn more. 

Install a green roof

City Hall green Roof rain gardenGreen roofs provide wildlife habitat, remove pollution from the air, lessen polluted runoff during storms, and reduce heating in summer and cooling in winter. Green roofs can also increase the lifespan of roofing materials, making them cost-competitive with conventional roofs. Consider installing a green roof on your home, business, garage, or shed. Over one-third of green roofs in Seattle are small projects (300-1,500 square feet) found on private homes. To see a local public example, visit Shoreline City Hall’s green roof.

Certified backyard habitat

The Washington Department of Fish and Wildlife instituted the Backyard Wildlife Sanctuary program to help offset habitat loss from development. The program certifies backyards in homes, schools, and public places that meet criteria for healthy habitat, which includes native plants, different sizes of plants from trees to groundcovers, a source of water, places to hide, and more.
