Project Scope


  • The site is currently unused (was previously used by the Church)
  • There are four buildings
  • There is parking for 127 vehicles
  • 57% of the site is covered with buildings and pavement / hardscape
  • The main church building is built up against the east property line
  • The basement level of the building is up to 10 feet below the sidewalk

North City Water District is working with Wagner Architects to develop a Site and Facility Master Plan:

  • The Plan proposes to remove all existing development, including all paving and buildings
  • City Development guidelines limit hardscape to 50%; the Master Plan proposes only 40% of the site be covered with hardscape (hardscape cannot grow to over 50%)
  • The plan assumes that 6 Water District staff will work on site; this may grow to as many as 10 staff
  • The Master Plan provides parking for up to 13 staff and visitors, removing 114 parking spaces; this will significantly reduce traffic and street impacts in comparison to the site’s former Church use
  • Proposed development height would be lower than the existing church height
  • Development will include an office-crew Administrative building, smaller operational buildings, and an operational yard
  • The surrounding neighborhood will be shielded from operations by walls and fences, along with open landscaped space
  • The two existing driveways into the site will be maintained, one from 15th and one from 158th
  • Public access, visitor, and staff parking, as well as the front door into the Administrative building, will all be from 158th

There will eventually be four buildings on site:

1.  Office/Crew Administrative and Shop Building:

  • Building:
  • Offices
  • Large workroom for field crews
  • Toilets, showers and lockers
  • Lunchroom
  • Areas to clean up and store wet gear
  • A series of regular bays with vehicle access
  • Secure small parts storage
  • Workshop for working on meters and hydrants
  • Enclosed vehicle parking
  • Covered area in front
  • Back wall will shield operations from the neighbors to the west

2.  Drive-Through Vehicle Wash Building:

  • A drive thru heated parking space for the Vactor will be attached

3.  Decant Building:

This is where vactor truck spoils are discharged. The vactor is used to excavate around water pipe breaks; the excavated soils are a watery consistency, like milkshakes. The decant building separates the water from the solids.

4.  Future Fueling Station:

We may construct this building in the future, to ensure District vehicles can be fueled in the event of a natural disaster; it will be covered by an open canopy.

An adjacent standby generator will provide power to the entire site, it will be secured with a weather and sound enclosure.

We are currently working to clarify development standards on the site:

  • The street frontage along 14th, 158th, and 15th will all be improved
  • One half of 14th and one half of 158th will be paved with new curb, gutter, storm sewer, and landscaping
  • The sidewalk and landscaping along 158th will also be modified
  • There will be a dedicated Landscape Section at 14th, and at the intersection of 15th and 158th

Project Financing

In order to keep financing costs as low as possible, we pursued bond financing. When the interest rates dropped in the summer of 2016, we had our bond rating reviewed by Moody’s Investors Service: they confirmed our outstanding operations with an ongoing Aa3 Bond Rating as of October 25, 2016.

With such a great rating, we went to the bond market and on November 2, 2016, sold $7.685 million dollars of 30 year revenue bonds which will be applied to this maintenance building as well as other capital improvement projects.


Mid-1940s:  the site of North City Water District (NCWD)’s current maintenance facility (located at the intersection of NE 169th Street and 15th Avenue NE in Shoreline), was also home to our administration operations. During the next 30 years as our service area grew, we outgrew both spaces, and began exploring other parcels.

1996: NCWD purchased an old bank branch building located at 1519 NE 177th Street in Shoreline and converted it into affordable Administrative Operations space. The Maintenance Facility remained at its same location (169th and 15th).

1997:  NCWD and the Shoreline School District jointly purchased roughly 20 acres at 23rd Avenue NE and NE 150th Street, known as the South Woods property, from the Department of Natural Resources. We split the cost, and divided up the parcels so that each District (Water and School) could meet their needs. Our intent was to eventually consolidate by locating three new facilities on this site: a new Administrative Operations Facility, a new Maintenance Facility, and a new Water Treatment facility.

2005-2006:  the City of Shoreline passed a Parks Bond measure; at the City’s urging, we sold our South Woods parcel to the City so they could convert it into a park with trails.

2010-2012:  the old bank branch building that we had converted into our Administrative Operations building was showing significant signs of failure. While performing a study to ascertain the problems and solutions, we also explored the idea of combining both Administrative Operations and Maintenance Facility on the same site. This combination required significantly more land, which we attempted to obtain, but were unsuccessful, so we proceeded with the Administrative Building renovation only.

Meanwhile we explored several options for meeting the ever-growing Maintenance Facility needs, including 1) expanding and remodeling the existing site; 2) attempting to co-locate with another District or Agency at another location; or 3) purchasing or leasing a larger property.  Option 1 was not feasible, as the existing site did not provide good turning radius for some of the larger District vehicles, and could not be expanded enough to meet our current and future needs for equipment storage, work space, a back-up generator, and adequate crew space. Option 2 was attempted with the City of Shoreline at Brugger’s Bog, but final arrangements were unsuccessful. This left us with Option 3.

2013-2014:  after exploring several different sites, The Northwest Church’s property came up for sale in the summer of 2013. We conducted a preliminary site and building analysis and determined this was the best possible location for our new Maintenance Facility:  it was conveniently located near the District’s main Administration Office, the site was amply sized to accommodate our needs, it had little or no use restrictions (such as wetlands or steep slopes), and the site featured two ingress/egress points which would allow larger vehicles to access the site with ease. We purchased the 3.2 acre site from the church in February 2014 for $3.3 million dollars.

2014-2016:  The Northwest Church began renovating their new facility on Scriber Road in Lynnwood, while still using their existing site for services. Once their renovation was complete and the church moved to their new home, North City Water District conducted a more in-depth study to determine whether we should reuse the church’s existing structures, or remove and replace them with a more energy efficient facility. It soon became apparent that the existing structures were too big for our needs, which would cost more for us to convert, as well as to maintain over the life cycle of the site. In September 2016, after a formal Request for Qualification process, the District selected Wagner Architects to help us redesign the site for our maintenance facility.

2017:  we’ve held Public / Neighborhood Meetings in April and November to gather input and opinions about the site’s development, and look forward to working with our neighbors in the upcoming year as we further refine the vision for our site.
