BACKGROUND After annexation of the Tukwila South area into the City in 2009 infrastructure including roads, water, sewer, and stormwater was constructed. The sanitary sewers were built using a combination of City and grant funding. The City's cost will be recovered through payment of connection fees as each lot in the area is developed. DISCUSSION Sewer connection fees for Tukwila South and the adjacent residential lots accessed from Orillia Road were adopted in 2014 as TMC Chapter 14.19. The ordinance calculated the connection fee by dividing the total construction cost minus grant funding by the total area served. Then each lot was assessed a connection fee based on the L12-027 Preliminary Plat lot pattern. However, this plat was not recorded and was superseded by a different lot layout in Plat L17- 0031. Only the first phase of that plat was recorded and it has now expired. A new Preliminary Plat with a different lot pattern was submitted in 2024 and was recently approved. The proposal is to change the calculation of the connection fees to be based on a cost per square footage of each lot at the time it is developed and eliminate references to specific lots as those may continue to change over time. FINANCIAL IMPACT There will be no change to the City's overall cost recovery for the sewer construction, only the method of calculating fees will change. A fixed cost per square foot will be easier to calculate and more adaptable to future lot configurations. RECOMMENDATION The Council is being asked to approve the ordinance and place this item on the consent agenda at the June 2, 2025 Regular Meeting. ATTACHMENTS A.
