The major components of plan implementation include utility rate implementation, staffing needs, additional resource needs, completion of PIC projects that address existing stormwater issues, interdepartmental collaboration, and interagency collaboration.
The activities and projects listed in this section would be funded by revenue from the stormwater utility. A financial analysis was conducted to define utility rate adjustments that are necessary to implement this plan.
In October 2019, the City approved the following stormwater rates for 2020 through 2025 to support the implementation of the Minimum tier of SWMP activities and the Priority CIPs.

ADDRESSING STAFFING NEEDS
Under the current level of staffing, City staff are not able to meet all the current requirements of the NPDES permit and will not be able to address the new activities. Also, current staffing levels will not be adequate to meet the new and expanded requirements of the 2019–2024 Phase II Permit and defined SWMP goals during future years. Refer to Appendix E for a detailed estimate of staffing needs.
The City will need staff to manage the construction management and project management aspects of proposed CIP projects. These costs are included in Appendix G.
Schedule of CIP project Implementation (SWMCP Table 6-1 pg. 73)
CIP projects were developed for known problems that include issues such as neighborhood-scale flooding, poor water quality, and failing infrastructure.
The City will implement stormwater CIP projects in the order shown in Table 6-1.
There are several projects that are not included in this plan due to high costs and low relative priority. These projects include additional flood reduction projects in the Scriber Creek Corridor, including the eventual raising of 44th Avenue West where the temporary flood notification signage is planned.
