Clark County Public Works Clean Water division owns property at 5600 NE 129th St. in Vancouver. The property contains underground stormwater control structures and above-ground recreational facilities. Clark County maintains the stormwater facilities and the Philbrook Farms homeowners association maintains the recreational facilities. The stormwater facilities have not been performing as designed, causing over a foot of water to flood the basketball court and playground during periods of rain. Testing during the winters of 2021-2022 and 2022-2023 indicated that rapidly rising groundwater levels during rain events contribute to the flooding, resulting in closures to recreation facilities during the rainy season.
UPDATE - November 2023
Clark County has determined the area will need to be fenced and closed from November 2023 to June 2024. Temporary fencing was installed the week of Nov. 13
Groundwater monitoring activities have concluded, but the county continues to monitor the system’s water levels and its overflow. Currently, county staff are evaluating the feasibility of short and long-term solutions. We will provide an update to residents in spring 2024 on next steps.

Project timeline
We anticipate completing a plan for short and long-term improvements as early as spring 2024. Depending on repair options, and construction schedules installation of short-term improvements could begin as early as fall 2024.
Budget
The estimated budget for interim improvements is $225,000, which is funded from the 2024-2029 Stormwater Capital Plan. This will include short-term access improvements. Long-term flooding solutions are likely to exceed current budget and will be addressed in future capital plans.
