Sherman Avenue Stormwater Park

The City has engaged with neighborhood residents two times since beginning the engagement process in November 2024. The first outreach included a neighborhood-wide digital survey advertised with 636 doorhangers on apartment building residences, 852 postcards mailed to single-family residences in the project area (shown below), and 30 posters posted in nearby businesses. The second engagement opportunity was an in-person workshop on September 17^th at City Hall. The workshop was announced through another mailing of 852 postcards to neighborhood residences, posters hung at nearby businesses, and graphics shared on the City's social media pages.

The first engagement feedback helped the City form three design alternatives which was presented at the workshop to refine and confirm the direction of the design concepts. Check out the results to each outreach method below.

In 2022, the City of Port Orchard purchased a 30-acre property located at the south end of Sherman Avenue near Blackjack Creek (see the property outlined in black below).  The property was purchased to provide a regional stormwater facility that would facilitate the development of sidewalks and road improvements in the surrounding neighborhood and to provide a neighborhood park. The City is continuing the public outreach process to determine neighborhood preferences for how the property should be developed and to develop a park master plan for the property.

When it rains, water flows across hard surfaces like streets, roofs, and yards, picking up pollutants along the way. The City’s drainage system, made up of pipes and ditches, helps direct this runoff to local waters like streams and Sinclair Inlet. This system helps protect homes, roads, and other infrastructure from flooding and damage.

In more recently developed areas of the city, pipes and ditches lead to large stormwater detention and infiltration ponds that allow for infiltration of stormwater to groundwater and/or attenuate the flow of stormwater to local waters.  These ponds are often fenced off and aren’t always attractive.  Recently, efforts have been made to design more attractive stormwater facilities that are integrated into the design and co-located with park and recreation facilities.  These projects are known as stormwater parks.

Stormwater parks, like the proposed Sherman Avenue facility, can help reduce the harmful effects of stormwater on our environment while providing park improvements for residents. They clean and control runoff before it reaches important areas like streams, beaches, and groundwater. This is important for protecting wildlife such as salmon and keeping water safe for recreation and local seafood like shellfish.

Stormwater parks can be a component in maintaining healthy watersheds, the areas of land where water flows into streams and the sea. These parks can reduce flooding and improve water quality, making our community more resilient while providing public recreation amenities, educational opportunities, and increased access to neighborhood green space.
