Bitter Lake Reservoir Improvement Project 

Fall 2026 Update

Multiple construction vehicles doing earthwork at the construction site.

Construction for the new reservoir continues. SPU’s contractor spent the summer demolishing the decommissioned reservoir, excavating concrete and soil around the site, and installing new pipes. Over the next few months, the contractor will continue pipe work and begin pouring concrete for the new reservoir in sections. The contractor is also preparing the site for the rainy season. Adjustments are being made for how stormwater is directed and treated before it flows into the city drainage system.

What to expect

  • SPU and the contractor are using Best Management Practices to reduce construction-related noise, dust, and vibrations during work hours. This includes backup alarms for safety, heavy vehicle use, and power tools.
  • Temporary traffic impacts to accommodate construction vehicles. Flaggers may direct traffic. You may see a higher volume of construction vehicles on days where we are pouring concrete for the new reservoir.
  • We will store equipment, materials, and some excavated concrete and dirt on site for later use.

SPU and the contractor are following City of Seattle standards and regulations for noise, dust, and vibration. To learn more about these practices, visit www.seattle.gov/utilities/construction-resources.

Fall work hours

Beginning this fall, the contractor is expecting to work from 6 AM-6 PM Monday through Friday. There may be periods where they choose to work longer days to complete construction activities. Weekend work may be required as dictated by project needs.

Site lighting changes

The contractor has changed their site lighting plans due to recent break-in attempts. Moving forward, site lighting will be on throughout the night to discourage future break-in attempts. Site lighting will have hoods around the bulbs to minimize light shining into nearby homes.

City Council names six finalists for District 5 vacancy

Public Forum with finalists on Monday, July 21

Today, July 17th, in a special meeting, the City Council named six finalists to fill the vacancy representing District 5, left by former City Councilmember Cathy Moore.

A list of 22 eligible applicants with completed application materials was made available to the public on the Council Vacancy webpage on Friday, July 11. Councilmembers chose the six finalists from the list of 22 qualified applicants provided by the City Clerk.

The Council has also selected Unified Outreach to host a public forum with the finalists, giving the community a chance to hear from the candidates before the final selection is made. Each of the finalists is required to participate in the public forum and in a July 22 Special Council Meeting in order to move forward in the process to fill the Council vacancy.

The public forum will be held on Monday, July 21 from 5:30 p.m. – 8 p.m. in the Auditorium, Room LB 1207, first floor of the Library Building at North Seattle College, located at 9600 College Way North in Seattle. Moderators will be Ed Dumas, Executive Director of Unified Outreach, and April Goode, Operations Manager. 

Community members attending the public forum can request an interpreter, translation or disability accommodation, if needed. The public forum will also be streamed live on the Seattle Channel.

Background

Councilmember Cathy Moore resigned her seat on the Seattle City Council, effective July 7, 2025, leaving a vacancy on the Council. The City Charter gives the Council 20 calendar days to fill a vacant Council position, which ends on July 28. From the date of the appointment, the newly appointed councilmember will serve until the 2026 General Election results are certified and a successful candidate has been sworn in. 

What’s next

The Council will meet on July 22 to interview finalists. A vote on the final appointment is expected to take place on July 28. The successful candidate will need to gather a simple majority of five votes from the Council.

ADUs and Middle Housing Update

by  on July 7, 2025

On June 30, 2025, several adopted pieces of legislation became effective in Seattle related to compliance with State laws aimed to boost housing supply and diversify housing options in Seattle’s residential zones. These code changes, put forward by Mayor Harrell and adopted by Council, are known as the HB1337 and HB1110 Compliance Bills (Ord. 127211 and 127219 respectively).

The changes to the Land Use Code create a flexible framework to boost housing supply that aligns with state goals to address Washington’s housing shortage, estimated at 140,000–250,000 units. These changes will diversify housing options and reduce barriers to constructing Accessory Dwelling Units (ADUs) and several other housing types, often referred to as Middle Housing. Together, these laws position Seattle to accommodate population growth, reduce sprawl, and enhance housing access.

ADUs

Seattle’s previously adopted ADU rules varied by zone. All general standards for ADUs are now consolidated in SMC 23.42.022 and are consistent between all zones that allow residential development. The new ADU standards also include more flexibility including:

  • Allowing two ADUs per lot in addition to a primary unit on all lots.
  • ADUs can be configured as one or more units in detached, attached, or stacked apartment flat configurations.
  • Reduced requirements for an attachment between units (minimum 3 feet of attachment).
  • Setback and height standards have been loosened to be no more restrictive than those for the primary home.
    • Additional height up to 32 feet in most Neighborhood Residenetial zones and higher in the Lowrise zones.
    • ADUs are allowed in the rear yard up to 32 feet.
  • Size limits for ADUs have been raised to 1000 square feet across all zones where they are allowed.
  • ADUs are exempt from street improvement requirements regardless of zone.

Middle Housing

The second ordinance, the HB1110 Compliance Ordinance, will adopt new rules to encourage several types of housing Citywide. This ordinance will allow up to 4 units on every residential lot and up to 6 units when the development provides low-income housing or is located near major transit stops. Code changes to the Neighborhood Residential and Lowrise code are extensive and include measures such as:

  • Increased density. Existing lots, even those that are less than 5000 square feet, are allowed increased density of 4 units or 6 units if the lot provides low-income units or is near a major transit stop.
  • A broader range of housing types in what has historically been single family zoning. These unit types include:
    • Detached units, such as stand-alone residences or cottage housing
    • Attached units, such as a townhouse or rowhouse developments
    • Stacked apartment flats
  • Increased lot coverage allowances and reduced minimum setback requirements to accommodate more units on a lot.
  • Height limit increases in all Neighborhood Residential and Lowrise zones.
  • More flexible amenity area standards in Lowrise zones.
  • Elimination of bicycle parking and bike parking storage requirements for all middle housing types.
  • Increased requirements for Electric Vehicle (EV) ready parking.
    • Private parking spaces in a development need to be EV ready
    • The first 12 parking spaces in a parking area serving multiple units needs to be EV ready
    • Residential parking areas with more than 24 units need to provide EV ready stalls for 45% of the spaces

Our online Seattle Municipal Code may take several months to be updated to the new regulations and so a consolidated version of these codes is provided on the Office of Planning and Community Development’s website. If you have questions about these new rules, visit our website or submit your question to our Virtual Applicant Services Center. See our Opinion Letter page for a list of our paid land use information services for specific questions regarding the eligibility of an existing lot to accommodate additional density or to request more detailed zoning information.

Aurora Ave N Bus Lane Changes Coming

Aurora Ave N Bus Lane Hours Expanding to 24/7

.

We are reaching out to share updates about changes to the bus lanes on Aurora Ave (SR 99). In the next month, we’re changing the existing bus/parking lanes on Aurora to be bus-only lanes and prohibiting parking to support reliable transit trips throughout the day.

These changes are taking place in preparation for increased traffic expected during upcoming construction on I-5 as part of the Washington State Department of Transportation’s (WSDOT) Revive I-5 program.

The Aurora bus-only lanes are currently in effect during morning and evening peak commute times. They will change to be in effect all day, every day as new signage is installed this spring. This will help ensure a reliable trip for people on the RapidRide E Line, while managing extra traffic on Aurora Ave during the upcoming I-5 lane closures. The expanded bus lane hours are expected to take effect before the start of Revive I-5 construction. We have been working together with businesses and the community along Aurora Ave to prepare for these changes.

What’s changing with Aurora Ave bus lanes?  

  • Southbound: One lane from N 115th St to N 38th St will become a 24/7 bus lane.
  • Northbound: One lane from N 38th St to N 59th St, and from Winona Ave to N 115th St, will become a 24/7 bus lane.  

       What to Expect:

  • Starting as soon as late May, bus-only lane signs will be installed along Aurora Ave.
  • As the new bus-only lane signs are installed the new 24/7 bus lanes will go into effect. These lanes will operate all day, every day, instead of only during peak travel times.

What does this mean for parking and loading?

  • In general, the expanded hours of the bus lane mean there will no longer be parking or loading on Aurora as the new bus-only lane signs are installed. A few additional signs are being installed in locations where there will be parking and loading exceptions.
  • We recognize this is a change from your current routines. We encourage you to take transit to get to destinations on Aurora. For more information on ORCA transit passes, please visit Home | ORCA.
  • King County Metro offers discounted transit passes for employees and multifamily residents.  Please visit their websites for more information: ORCA Business Passport. and ORCA Multifamily Development Passport
