City staff described a Crystal Beach Pool storm‑drain issue revealed during recent flooding and recommended replacing the existing concrete case so a backflow preventer can be installed. Christian Hansen told the board that the existing case cannot accommodate the device and that the installation will reduce the risk of stormwater running back into the pool and adjacent properties.

Hansen said the work includes replacing the concrete case and installing a check‑style backflow valve; the department has been inspecting and repairing related sump pumps and has set alarms on the basement sump pump. Staff confirmed a previously quoted price of $8,900 for the work and recommended accepting the Sedam (Sedan?) Contracting proposal. The board approved the contract by voice vote.

Hansen noted that the measure would reduce early flood ingress to the pool and nearby properties but would not prevent flooding in an extreme event that overtops the system. The department will continue periodic checks and monitor sump pump performance during rain events as part of routine maintenance.
