The Jefferson County Code is current through Ordinance 08 -20, passed November 16, 2020.
18.30.040 Sewage disposal.
(1) All development shall be provided with an individual, on-site septic system and drainfield approved by Jefferson
County public health in compliance with Chapter 8.15 JCC, unless Jefferson County public health determines that
public sewer is available which would then require connection to the approved public sewer.
(2) Design and construction standards for on-site sewage disposal shall conform to the requirements of Jefferson

(3) Large on-site sewage systems (LOSS) and community drainfields are not considered a sanitary sewer system as
applied under the Growth Management Act. Jefferson County considers these systems a rural governmental service.
(4) New construction of a sanitary sewer system, extension, or connection to a sanitary sewer system located outside
of an urban growth area may only occur if:
(a) The new sanitary sewer system, extension, or connection is a necessary response to protect basic public
health, safety, and the environment; the sewer is financially supportable at rural densities; and, the sewer,
extension, or connection does not permit urban development;
(b) The new sanitary sewer system, extension, or connection is necessary to support a Limited Area of
More Intensive Rural Development (LAMIRD); the sewer is needed to mitigate a threat to the public
health, welfare, or to protect an area of environmental sensitivity caused by existing development; and the
sewer is limited to those properties or facilities needed to mitigate the threat to the public health, welfare, or
to protect an area of environmental sensitivity;
(c) The new sanitary sewer system, extension, or connection is necessary to provide service to an essential
public facility if no practicable alternative exists to site the essential public facility in an Urban Growth
Area; or,
(d) The new sanitary sewer system, extension, or connection supports schools sited in a rural area that serve
students from a rural area and an urban area, when consistent with the Jefferson Cou nty Comprehensive
Plan, RCW 36.70A.213, and the following requirements:
(i) The applicable school district has adopted a policy addressing the school service area, facility
needs, and educational program requirements;
(ii) The applicable school district has made a finding, with the concurrence of the county
legislative authority and the legislative authorities of any affected cities, that the proposed site is
suitable to site the school and any associated recreational facilities that the applicable district has
determined cannot reasonably be collocated on an existing school site, taking into consideration
the extent to which vacant or developable land within an urban growth area meets those
requirements;
(iii) The county and affected cities agree to the extension of sewer to serve the school sited in a
rural area that serves urban and rural students at the time of concurrence of subsection (4)(d)(ii);
(iv) Any impacts associated with the siting of the school are mitigated as required by the State
Environmental Policy Act, Chapter 43.21C RCW; and,

shall allow the sewer to serve a property or properties in addition to the school if the
property owner so requests, provided that the county and affected cities agree with the

district may, for a period of time not to exceed 20 years, require reimbursement from a
requesting property owner for a proportional share of the construction costs incurred by
the school district for the extension of the sewer.
