Contract No.: 27 Project No. : 150338 Date: February 3, 2020
Client: Kittitas County
Project Name: Potential Aquifer Recharge Site – Naneum
Description of Work Cost
Kittitas County (County) has broad coverage in its water bank for developable
lots in the County, as well as full back-mitigation for existing rural exempt users
through its implementation efforts from 2009 to 2019. In 2020, the County’s goal
is to:
1. Expand parcel suitability in areas where significant development potential
remains and a mitigation project is likely to be successful.
Aspect Consulting, LLC (Aspect) has been assisting the County on water bank
implementation since 2014 and proposes to provide technical assistance as
follows:
Task 1: Upper Teanaway and Naenum Mitigation
Developable lots exist in these subbasins that, despite the County’s best efforts,
do not have a likely full-season water right identified for acquisition and
mitigation. The County has developed options for mitigation in these locations by
collecting funds for in-lieu non-water right acquisition projects, and by partnering
with local developers on a consumptive use recharge pilot. Potential exists to
develop regional aquifer recharge sites in the Teanaway and Naenum basins that
can mitigation for the remaining developable lots using a future cost-share with
those lot owners. Depending on local site conditions, opportunities may also exist
for instream flow enhancement goals as part of the Yakima Integrated Plan, and
funding from that source or the Streamflow Restoration Grant Program may exist
if the proof of concept can be demonstrated. To investigate the feasibility of
regional mitigation in these hard-to-serve areas, Aspect will:
A. Coordinate with the County to identify and describe potential priority
locations in the Upper Teanaway and Naenum basins.
B. Describe the ownership and access characteristics of these sites.
C. Use geologic and soil mapping to predict ranges of infiltration rates that could
be available in target locations.
D. Use analytical methods to estimate likely fate, transport, and timing of water
at the sites.
Aspect will complete
this work on a time-
and-materials basis,
not-to-exceed:
$10,000
Change Order No. 27
Project No. 150338

E. Provide example water budgets for typical Package A and Package B
mitigation requirements.
Aspect will summarize its findings in a technical memo and meet with the
County. The goal is to provide foundational proof of concept support at these sites
for one or more grant applications in the 2021 funding cycle for a pilot
demonstration project. Aspect will complete this work on a time-and-materials
basis, not to exceed $10,000.
This change amends contract between Aspect Consulting, LLC and Client dated November 6, 2013 and
incorporates the attached Schedule of Charges. Except as amended above, all terms and conditions of
contract apply to this contract change.
