surface & stormwater management performance audit final report

Surface & Storm Water Management Performance Audit
Kitsap County, Washington
Final Report
• Catch Basin Cleaning - R.W. Beck recommended that the Program conduct annual
cleaning of all catch basins. The Program has actually cleaned more than 100% of its
catch basins in each of the last two years (cleaning has been required for certain catch
basins more frequently than once a year). Program personnel report that the costs
associated with satisfying this recommendation has been less than the amount assumed
by R.W. Beck.
• Pollution Prevention Plans - R.W. Beck recommended that the SSWM Program develop
Pollution Prevention Plans for County-owned facilities. These plans have been
completed.
• Street Sweeping - R.W. Beck recommended monthly sweeping of all curbed streets. This
activity is the responsibility of the County Roads Department. During winter months, the
current goal is to pick up sand within two weeks of its application. During the summer
months, streets are swept on an as-needed basis. It is not expected that the Phase II
Permit will require a change in the County’s current street sweeping frequency.
• Facilities, Parks and Recreation Department Impacts - The Phase II Permit would
require that maintenance of stormwater facilities in County parks also be performed in
accordance with the pollution prevention minimum control measure requirements. This
would be the responsibility of the County Facilities, Parks, and Recreation Department.
SSWM Program personnel report that they have completed some work on behalf of the
Facilities, Parks, and Recreation Department and other County departments, and as a
result a somewhat better working relationship has developed.
Observation: There are a number of SSWM program elements that are not required by the
NPDES permit, but Kitsap County has other state requirements and its own requirements that it
fulfills through its SSWM program.
To determine what SSWM program elements are required versus those that are discretionary, the
program elements were compared to the NPDES requirements. As noted in Chapter II, the
Board of Commissioners established the SSWM Program for a broad number of purposes that
are not solely related to the NPDES permit requirements. As a result, there are a number of
SWWM program elements and certain tasks of other program elements that are not required by
the draft NPDES Phase II Permit requirements (i.e., these program elements go beyond the
minimum requirements of the Phase II Permit). Exhibit 10 shows the SSWM program elements
by department/agency and shows what program elements are required and discretionary. A more
detailed analysis is in Appendix B.
