j. Is the City planning on doing in-person interviews?
i. If the City determines interviews are necessary for making a consultant
selectfon, they will be conducted virtually by Microsoft Teams or Zoom. City staff

k. Does the budget in the RFQ include both City and Consultant Costs?
i. The Sam Chastain Trail feasibility study project is entfrely funded by a grant from
the Washington State Department of Commerce with no additfonal project
funding currently available. The antfcipated budget of $415,000 for the
preliminary consultant scope of work included in the RFQ considers a total finite
project budget of $485,000, which also covers previously expended consultant
(i.e., pre-grant contract cultural resources study) and miscellaneous publishing
costs (e.g., DJC publishing fee) in additfon to consultfng fees for this scope of
work. No additfonal project funding is currently available.
l. What consultants assisted in the grant applicatfon whether it be cost estfmatfng or scope
development and are they excluded from the RFQ response? If work was completed,
was it solicited under an RFQ process or with a different project?
i. All materials developed in support of the grant with the Washington State
Department of Commerce were produced in-house by City staff. This project has
been ongoing for decades, a number of consultants have been involved at
various points, and no one is excluded from responding to the RFQ.
m. Have agency coordinatfon meetfngs already occurred with regulatory agencies? If so,
which ones?
i. While the City maintains relatfonships with regulatory agencies, no recent
coordinatfon meetfngs have occurred with regulatory agencies for the Sam
Chastain Trail Project. The selected consultant team will be expected to lead
and/or support coordinatfon meetfngs with the appropriate regulatory agencies.
n. Which project partner relatfonships are already established, and which will need to be
developed by the selected consultant?

will rely on the selected consultant to lead and/or support project partner
coordinatfon and engagement.

i. The City collaborated with all partfes involved in restoratfon efforts on DNR
property including during project permitting. As a result of this coordinatfon, the

connectfon across DNR property. The restrictfve covenant is available at the

p. Will teams be expected to build upon previous technical work or start with a fresh
evaluatfon of alternatfves?
i. The City is open to recommendatfons for alternatfve project approaches.
However, teams may consider previous technical work to determine its
relevance and feasibility under current conditfons.

assistance antfcipated? (Facilitatfon, supportfng graphics, translatfon services, etc.)
i. Please refer to the City’s response included under Questfon “c”. The City will

or stakeholder engagement, as well as partfcipatfon at key
meetfngs/engagement opportunitfes. Translatfon services are not antfcipated to
be a component of this scope of work. The final scope of work will be developed
with the selected consultant based on City needs and consultant
recommendatfons.
