We are beginning Phase 2 design! The City of Sammamish is continuing improvements to SE Issaquah-Fall City Road/SE Duthie Hill Road corridor. We are beginning design for Phase 2 which is between Klahanie Dr SE and SE Issaquah-Beaver Lake Rd to improve safety and traffic flow for all users. Our design team is going to be busy the next few months gathering information and developing the preliminary design concept. We’ll share the concept and ask for your feedback this fall.

What's the latest?

  • Share your input to continue helping establish the project vision and priorities via our interactive map below! Your feedback will help us develop the preliminary design concept. Thanks to everyone who participated in our initial survey! Stay tuned for a summary.
  • Sign up for email updates to stay up to date on project updates and upcoming opportunities to get involved and provide feedback. We will be hosting a Virtual Open House to share our findings, design progress, and recommendations with the community, as well as presenting to City Council, in early 2021.

Why are improvements needed?

The SE Issaquah-Fall City Road/Duthie Hill Rd corridor is a vital connection route to residents of the City of Sammamish and surrounding communities. With recent decades of community growth, the needs of this old rural corridor have evolved, and change is needed. Updates are being made to better traffic flow and promote the City’s goal of complete streets by including bike lanes, sidewalks, and landscaping along with other safety and environmental improvements.

Phase 1 of the corridor which extends from 242nd Ave SE to Klahanie Drive SE is currently under construction. Phase 2 will extend improvements from Klahanie Dr SE to SE Issaquah-Beaver Lake Rd.

Preliminary design concept:

The preliminary design concept is based on the City’s Arterial Street standard consisting of two travel lanes, a center turn lane or planted median, bike lanes, sidewalks and streetscaping. We are currently gathering community input and data from various traffic and environmental studies to refine the preliminary design concept. Sign up for email updates to stay tuned for upcoming opportunities to learn more about the preliminary design concept and provide input.

To the right of the trail are trees and grass that separate the trail from an eight foot shoulder. To the right of the shoulder are two eleven foot wide drive lanes that are separated by a yellow line. To the right of the drive lanes is a four foot wide shoulder. To the right of the shoulder is trees and grass.

To the right of the trail are trees and grass that separate the trail from an six foot wide sidewalk. To the right of the sidewalk is a six and a half foot wide planter area. To the right of the planter area is a five foot wide bicycle lane. To the right of the bicycle lane is a eleven foot wide drive lane. To the right of the drive lane is a twelve foot wide center turn lane. To the right of the center turn lane is an eleven foot wide drive lane. To the right of the drive lane is a five foot wide bicycle lane. To the right of the bicycle lane is a six and a half foot wide planter. To the right of the planter is a six foot wide side walk. Trees and grass are to the far most right of the image.

The project area today:

The corridor today consists of two-lanes with shoulders and open ditches, and lacks sidewalks, landscaping, and designated bike lanes. Numerous driveways are along the south side of the corridor to access homes, schools, and small businesses; and Klahanie’s pedestrian trail and Green Space Preservation Tract is on the north side. Overgrown roadside vegetation often restricts sight distance and near Endeavour Elementary School, heavy rains in the winter often result in water over the roadway.

How will the community be involved in the Phase 2 design process?

The City’s goal is for the Phase 2 design to reflect the community’s priorities and input. Early in the design process we will be gathering feedback to inform the preliminary design process. In early 2021, the City will share updates and gather additional public input to refine the vision for the design. As design progresses, the City will continue to engage with the community to solicit feedback on specific design details, including landscaping, sidewalk and bike lane design, connections to community resources and amenities, and corridor aesthetics. We look forward to working with the community to develop this project to meet your needs and priorities.


We are committed to continuing to engage with the community while COVID-19 continues to impact our ability to meet in-person. Regular updates will be shared on this website, as well as via email updates, the City Newsletter, project mailers, and more.
