9.45.005 Introduction and purpose.

As land within the district continues to develop, additional units constructed or created on parcels increase the demand on the district’s water distribution and sewer collection systems. When a customer connects to the water and/or sewer systems, the district conducts evaluations to ensure that the district properly serves all customers and that all property owners bear their equitable share of the cost of the water and/or sewer system.

It is the purpose of this additional unit policy to formally address definitions, fees and charges and to provide additional technical requirements for these additional units as they pertain to water and sewer improvements; to the extent the requirements contained in this policy differ from or conflict with local agencies or the district standards and details, this document shall control.

It is not the purpose of this policy to regulate land use that is within the authority of other local jurisdictions but rather to provide rules and regulations that are limited to the authority provided to water and sewer districts pursuant to Chapter 57.08 RCW and other applicable law. This policy and the rules and regulations contained herein should be read in that context. [Res. 2022-8-1 § 1.]
