A local improvement district (LID) is a funding tool governed by state law, by which property owners pay to help fund the costs of public improvements that directly benefit their property. The Waterfront LID improvements are a multi-year investment in Seattle’s central waterfront totaling approximately $739 million and are anticipated to be completed in 2024.  Property owners within the Waterfront LID boundary area are contributing to a portion of the LID improvement costs based on the “special benefit” they receive from those improvements.  The LID is a key component of the Waterfront Seattle Program funding plan, along with City and State funding and private philanthropy. An LID was included in the Waterfront Strategic Plan and approved by Council in 2012.

As part of the Waterfront Seattle funding plan, Seattle City Council passed Ordinance 125760 establishing a Local Improvement District (LID) on January 22, 2019.

On June 14, 2021, Council passed the Waterfront LID Assessment Roll Ordinance No. 126374 confirming the Final Assessment Roll for the Waterfront LID.  The Final Assessment Roll is on file and available to be viewed at the Office of the City Clerk and online: final assessment roll.


On July 9, 2021, consistent with state law, the City of Seattle Treasury Division of the Finance and Administrative Services Department (FAS) mailed a Prepayment Assessment Notice to each owner or reputed owner in the LID boundary area to the address shown on the tax rolls of the King County Treasurer (see sample Prepayment Assessment Notice). The Prepayment Assessment Notice provided the assessment amount due for each parcel and contained information regarding the option to prepay the assessment in full or in part during an initial 30-day prepayment-period without incurring interest. The one time 30-day Prepayment Period concluded on August 10, 2021 and is no longer a payment option available to owners in the LID boundary area.


Beginning in 2022, and continuing through 2041 (the 20th anniversary of the end of the Prepayment Period), the City of Seattle Treasury Division of the Finance and Administrative Services Department (FAS) will send a LID assessment payment notice annually to each owner or reputed owner in the LID boundary area to the address shown on the tax rolls of the King County Treasurer.  LID assessment billing will be due on August, 10, 2022 and continue annually for 20 years or until the assessment is deemed paid in full.

As described in the Waterfront LID Assessment Roll Ordinance No. 126374, for the first 10 years (2022-2031) annual installments will be billed as interest-only installments, meaning that only the interest on the principal balance of the assessment will be due in years 1-10. In years 11-20, installments will be billed as interest plus equal annual principal installments.  This will result in a much larger assessment billing amount in year 11 compared to year 10 as illustrated in the table below. The outstanding principal balance of each LID Assessment bears interest at a rate of 3.78%.

There is no penalty for prepayment of all or any portion of the principal balance at any time.  Please note interest is paid in arrears and is not prorated. Any payment made after the annual payment due date is subject  to a full year’s interest.  Property owners may prepay assessments in full or in part at any time so long as all principal and penalties, together with interest payable through the next annual installment payment date, are paid.

The assessment is a lien on the property and remains a lien on the property until it is paid in full (or foreclosed upon). The lien and its priority are described in RCW 35.50.010. 

The City is unable to provide additional guidance regarding the LID in relation to finances. Property owners should seek advice from a financial advisor relating to refinancing or resubordinating a property in the LID.
