11-026.00 Spokane County 2011 Sewer Construction ProgramMemorandum of Understanding
Between the City of Spokane Valley and Spokane County
Pavement Replacement Cost Sharing and Drainage Improvement Costs
For the 2011 Sewer Construction Program
WHEREAS the City of Spokane Valley (the CITY) and Spokane County (the COUNTY)
desire to work collaboratively to construct portions of the COUNTY's 2011 Sewer
Construction Program together with CITY paving and drainage improvement projects;
and
WHEREAS the CITY desires that the roads impacted by the construction of sewers in
the 2011 Sewer Construction Program be reconstructed to the full preconstruction width
for an improved roadway surface; and
WHEREAS the CITY also desires that pavement replacement work be extended in
some areas beyond the limits of sewer construction; and
WHEREAS the CITY also desires that certain drainage improvements be constructed in
areas that will be impacted by the COUNTY's 2011 Sewer Construction Program; and
WHEREAS the costs of such full width repaving, additional length of road
reconstruction, and miscellaneous drainage improvements are not funded by the
COUNTY's Sewer Construction Program, and said costs will need to be paid by the
CITY; and
WHEREAS the 2011 Sewer Construction Program includes the Green Haven and
Micaview Sewer Projects within the limits of the CITY, as identified in the COUNTY's
adopted Six -Year Sewer Capital Improvement Program 2011 -2016.
NOW THEREFORE, the CITY and the COUNTY do hereby agree as follows:
1. Prior to the bid of each project, the COUNTY shall provide the CITY with a set of
project plans, together with a cost estimate indicating the extent of pavement removal
and replacement to be paid for by the COUNTY as a part of the sewer project. The
CITY shall review the plans and estimate, and shall advise the COUNTY regarding the
extent to which the CITY desires to add pavement removal and replacement, as well as
the specific drainage improvements that the CITY would like to make in conjunction with
the project.
2. The CITY has requested that the COUNTY, through the Division of Engineering and
Roads, prepare a road design for a segment of Barker Road located within the 2011
Sewer Construction Program. The CITY intends to include the associated work in the
construction contracts for the sewer projects. The scope of work and design cost
estimate for this roadway is presented in Attachment A to this Memorandum of
(2a11- v2�
Memorandum of Understanding
2011 Sewer Construction Program Page 2 of 3
Understanding. The CITY will coordinate this design work directly with the Road Design
Engineer in the Division of Engineering and Roads. The Division of Engineering and
Roads shall invoice the CITY on a monthly basis for this road design work.
3. The COUNTY shall include the additional road and drainage work outlined in
Paragraphs 1 and 2 above in the bid documents for the applicable sewer project area.
4. After the bids for a project are opened, the COUNTY shall prepare the bid tabulation
and provide a copy to the CITY, typically within 24 hours, together with an estimate of
the CITY's share of the project cost based upon the unit prices submitted by the lowest
responsive bidder. The calculation of the CITY's share will include a representative
credit for the COUNTY's avoided cost of crack sealing and surface sealing that would
be associated with partial road width removal and replacement. If the CITY then
decides to proceed with the desired improvements, the CITY shall provide a written
notice to the COUNTY within two days of the receipt of the bid tabulation.
5. The CITY and COUNTY agree that the minimum pavement section for local access
roads in the 2011 Sewer Construction Program shall consist of two (2) inches of hot mix
asphalt overlying four (4) inches of crushed rock, which has been the historical practice
for the Septic Tank Elimination Program, and which is an exemption from the new road
paving standards adopted for the CITY.
6. The CITY's total estimated share of the construction and design costs are presented
in Table 1 below. The estimates in Table 1 are based on a minimum pavement section
for local access roads consisting of two (2) inches of hot mix asphalt overlying four (4)
inches of crushed rock.
7. The CITY and the COUNTY recognize that the estimated costs shown in Table 1 are
for planning purposes, and that the actual costs billed to the CITY will be based upon
final quantities and actual contract prices. The CITY's maximum cost for the 2011
projects shall not exceed $ 900,000 without written authorization by the CITY. The
COUNTY shall not proceed with any work that would increase the CITY's cost to an
amount greater than the total amount authorized.
8. If the CITY subsequently elects to make additions to the scope of any project, the
CITY shall request such additional work in writing. A corresponding adjustment shall
then be made to the CITY's share of the cost based upon the resulting increase in pay
quantities and the associated contract bid prices. For work items requested by the
CITY that are not covered by the contract bid prices, the COUNTY shall prepare a
change order for the CITY's review and acceptance prior to work items being
constructed.
9. As paving operations are undertaken for each project, the COUNTY will send
progress invoices (no more than one per month) to the CITY for the CITY's portion of
the cost of roadway and drainage improvements. When all paving and drainage work is
completed on a project, the COUNTY will send a final invoice to the CITY for the
Memorandum of Understanding

remainder of the CITY's portion of the project costs. For each project that is not
completed by the close of the 2011 construction season, the COUNTY will send a
progress invoice to the CITY prior to December 31, 2011.
