SUBJECT: Mason Street Neighborhood - Domestic Water Service Availability
CC: Bob Collins, Tim Pula, Darren Sandeno
PROJECT NUMBER: 217-9085-002
PROJECT NAME: Mason Street Neighborhood
Introduction:
The purpose of this technical memorandum is to request formal documentation from Jefferson
County Public Utility District that the Mason Street Neighborhood Development Project (Project) can
be adequately serviced by the PUD’s domestic water system.
Background and Purpose:
The Project is a residential subdivision project owned by Habitat for Humanity of East Jefferson
County. The project site is Parcel 901-023-007 in Port Hadlock-Irondale, Washington in Jefferson
County. The site is generally located between the intersection of Mason Street and Cedar Avenue.
The Project proposes constructing 138 residential lots – consisting of duplex, fourplex, and group
homes –amongst supporting utilities, roadways, and open space improvements. The Project is
beginning the land division process with the County by completing the Long Subdivision application.
Per the Jefferson County Code (JCC) 18.30.030, when development or redevelopment require the
availability of a supply of potable water, potable water shall be delivered by a means approved by the
Washington Department of Health and/or Jefferson County public health, and per JCC 18.35. 280
(8), a long subdivision application shall require documentation of water availability and adequacy for
each parcel affected sufficient to meet requirements of JCC 18.30.030.
A review of survey data and the Jefferson County PUD 2020 Water System Plan indicates that there
are existing water mains located in Mason Street and Cedar Avenue surrounding the Project site.
Approximately 138 equivalent residential units (ERU) are estimated to demand water service from
the PUD. Preliminary discussions indicate that the PUD has sufficient water rights availability and
water service capacity within the Quimper Water System to service the Project.
Conclusion:
Parametrix is requesting formal documentation from Jefferson County Public Utility District
confirming the availability and adequate capacity in its domestic water system to provide potable
water to the Project.

Single Family Group Home 2 1 2
Two single story group homes for adults needing supersivision and care. Eachbuilding has 8 single-
occupant bedrooms, shared kitchen facilities and shared restrooms. There isn't a perfect match on your
chart so I treated this as a multi-family building with each bedroom counting as a unit.
Single Family Duplex - 1 Story 16 1 16
Duplex is two single family homes sharing a common vertical wall. In our case each 1 story house is
attached to a 2 story house.
Single Family Duplex - 2 Story 32 1 32
Duplex is two single family homes sharing a common vertical wall. In our case each 1 story house is
attached to a 2 story house.
