UPDATE OF 2022 COMPREHENSIVE STORMWATER
MANAGEMENT PLAN
In 2022 Herrera completed an update of the City of Pasco's Comprehensive Stormwater
Management Plan (CSMP). The City of Pasco (the City) has determined that the CSMP should be
updated to include the entire urban growth area (UGA) as well as a few other small areas within
the City in the CSMP. The City authorized Herrera Environmental Consultants (Herrera) to
prepare a scope of services and cost estimate outlining services that Herrera will provide to
update the CSMP to meet this need.
This scope of services includes a discussion of the activities, assumptions, deliverables associated
with the following tasks:
Task 7 — Project Management
• Task 8 — CSMP Update
The budget for this work is included as Exhibit B.
TASK 7 - PROJECT MANAGEMENT
Herrera will be responsible for ongoing management of this project, including preparing
monthly invoices, as well as coordination of work efforts with the City's project manager
(Michael Henao). Herrera's project manager (Joy Michaud) will have phone and e-mail contact
with the City's project manager and other City representatives on an as -needed basis with
regard to scope, schedule, budget, and invoicing.
Project management activities will include contract set up and close out as well as monthly
invoices and progress reports.

EXHIBIT A - SCOPE OF SERVICES
Assumptions
• The project will not require monthly meetings with City staff or planned project manager
check ins.
• It is assumed that project management activities will occur over a period of up to 3
months.
Deliverables
• Monthly invoices and progress reports
TASK 8 — CSMP UPDATE
Updating the service area covered by the CSMP will require updating all of the GIS files and the
associated figures and tables in the CSMP, as well as minor to substantive revisions to different
Sections of the CSMP as detailed in the assumptions below.
Assumptions
• Update of the CSMP is expected to require the following:
o Substantive changes to Section 2 of the CSMP, including the majority of the
tables and figures. These changes will require updates to GIS data and
regeneration of approximately 6 to 10 tables and 9 to 10 figures.
o Moderate changes to Sections 3, 5, and 6 of the CSMP. Updates to Sections 5 and
6 will focus on additional staffing and other needs associated with the expansion
of the City's service area due to the recent annexation of most of the UGA.
o Minor revisions to Sections 1 and 4 of the CSMP.
o There will be no additional assessment of problem areas or identification of CIPS
associated with this CSMP update.
o In the modification of the basin boundaries, all of the area recently annexed into
the City as well as any remaining areas within the UGA, but outside the City will
be included as part of Basin 6. The inholdings ("donut holes") inside the City
limits will also be included as part of Basin 6 but will be denoted separately as
Basin 6A.
