The Capital Improvement Program (CIP) was developed through a multiple step process. The CIP includes transportation projects, parks projects, and surface water projects. Within the Engineering Division, transportation related projects (sidewalks, bike lanes, corridor improvements, pavement preservation, etc.) are managed and implemented. Individual transportation projects are identified through analysis of past capital project requests, previously proposed improvements, currently funded projects and recently identified projects. Once projects are identified, a Project Description Sheet is prepared describing the project scope of work and current status. Project costs are updated regularly and known funding identified. Using a collaborative effort City Staff identify the highest priority projects and available funding is allocated to those projects.
Current Major Projects can be found through the City's home page, or accessed here.
Environmental Services Projects
The City has contracted with Herrera, Inc to analyze in-water plant treatment data that's been gathered since 2017 before and after each treatment. The data will be used to update the IAVMP.
Visit the Integrated Aquatic Vegetation Management Plan page for more information on the original IAVMP and its current status.
Future Capital Improvement Plans
Design will resume in 2019 to complete improvements along SR 522 between 57th and 61st Avenues NE to increase safety, improve transit reliability, and ease congestion on the west end of the city.
Past Capital Improvement Projects - Surface Water & Transportation
Budget: Surface Water Component: $633,500
The SR 522 Corridor Improvements were completed in multiple phases and stages. The ultimate goal of the entire SR 522 project was to increase safety along SR 522 and improve capacity for vehicles, pedestrians, and cyclists. During the project, all of the drainage was improved as well. Many new flow control and water quality facilities were added to greatly improve the water entering Lake Washington and Sammamish River.
This project will remove an existing culvert and replace it with a new fish-passable box culvert to eliminate flooding caused by Little Swamp Creek at NE 192nd Street.
Log Boom Park Pedestrian Bridge
Log Boom Park's original pedestrian bridge was damaged during a 2009 storm. This project sought to replace the previous bridge with a new pedestrian connection through a public easement on the marina property.
NE 181st St Culvert Replacement
In May 2008, a sinkhole developed in the NE 181st St roadway over the Tributary 0056 culvert crossing. Due to the structural deterioration of the culvert, an emergency permit was issued and the culvert was replaced with a fish-passable box culvert.
An undersized vault located 200' east of 72nd Ave NE and NE 170th St was clogged during a large storm in 2007. The storm caused a back-up of Tributary 0057 and created massive right-of-way flooding and closures. A fish-passable box-culvert was constructed and resized to accommodate flows and relocate the stream through a different conveyance system.
2011 Log Boom Park Restoration Project
Log Boom Park houses the Tributary 0056 outfall at Lake Washington. The outfall was failing and eroding the stream bank. Permanent erosion control measures were installed as well and stream bank restoration.
City Hall's renovations were completed in 2010 and feature many cutting-edge drainage technologies. City Hall is equipped with Low Impact Development (LID) structures like a green roof, permeable pavement, and rain gardens to reduce the amount of pollution-generating surfaces and increase the infiltration area.
