Community Concerns • Drivers roll through the stop signs • Safety of pedestrians in crosswalk
Proposed Concept • Narrow the roadway with curb extensions to slow traffic and reinforce desired travel speeds • Shorter street crossings with improved crosswalk striping for people walking • Striping for future planned bike lanes and Neighborhood Bikeway route on SE 56th/117th Ave SE
Design Elements: • Curb, sidewalk, and curb ramps • New marked crosswalks with opportunity for creative/artistic crosswalks for increased visibility • Striping for bike facilities • Landscape plantings where feasible • Opportunity for raised intersection
Construction Cost: $75,000 - $250,000 Curb extensions

Example modified raised crosswalk on SE 22nd St, east of 148th Ave SE
Community Concerns • Poor compliance with crosswalks near school on 119th Ave SE (drivers don’t consistently stop for students)
Proposed Concept • Enhance crosswalk at SE 52nd to improve safety and compliance of drivers stopping for pedestrians • Coordinate with school for preferred crossing guard locations with new enhanced crosswalk at SE 52nd St and new sidewalk on west side of 119th Ave SE
Potential Design Strategies: • Enhanced crosswalk with creative/artistic pavement markings for increased visibility • Modified raised crosswalk • Advance pavement markings (e.g. zigzag markings) for increased awareness
Construction Cost: $10,000 - $75,000

Community Concerns • Drivers roll through the stop signs • Stop sign visibility • Safety of pedestrians in the crosswalk
Proposed Concept • Enhance the intersection to improve safety and compliance with stop signs • Possible improvements include a raised intersection or traffic circle
Potential Design Strategies: • Reconstruct with landscaped traffic circle or as enhanced intersection to reduce speeds and improve accessibility • Construct curb on west side of street to narrow road and reinforce desired travel speeds • Raise pedestrian awareness with creative/ artistic crosswalks
Construction Cost: TBD
(based on preferred design strategy)
