King County WaterWorks Grant Agreement for Lake Fenwick Alum Treatment - Authorize Environmental Supervisor, Rowena Valencia-Gica noted that Lake Fenwick is on the state's "303d list", the list of impaired waterbodies, for phosphorus pollution. Excess phosphorus comes mainly from stormwater inputs from the surrounding Lake Fenwick watershed. A "hypolimnetic aerator" - basically a large fish-tank bubbler, was installed in the lake in 1994 to help sequester phosphorus to reduce large algae blooms in the lake. However, the amount of phosphorus pollution currently in the lake exceeds the aerator's capacity. ........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ Page I of 4 Packet Pg. 2 4.1 Public Works Committee CC PW Regular Meeting March 21, 2022 Minutes Kent, Washington The City is retrofitting the aerator to increase the oxygen in the lake. To control algal blooms and improve lake water quality, alum treatment can be combined with the aerator . Without the upgraded aerator and alum, treatments, it is estimated the lake may become toxic in 10 years. Alum inactivates phosphorus to prevent toxic algal blooms. The proposed alum treatment can reduce phosphorus and algae by up to 70%. A low dose alum treatment was applied to Lake Fenwick in 2011. Recently, several Western WA lakes have been treated with alum yielding significant water quality improvements. The best time to apply alum is in the fall. This project is critical to reduce the risk of future harmful algae blooms and o improve the recreational experience at Lake Fenwick Park. Lake Fenwick is a valuable and important natural resource for Kent, and this project helps o protect a key resource for the community. a MOTION: Move to authorize the Mayor to sign the King County WaterWorks Grant Agreement, in the amount of $150,000, for Lake a Fenwick Alum Treatment, subject to final terms and conditions R acceptable to the Public Works Director and City Attorney.

Proposed Revision to Residential Traffic Calming Program - Adopt Transportation Engineer, Erik Preston stated that the Residential Traffic Calming Program (RTCP) which was updated in June 2020, requires that 50% of mailed ballots must be returned and 67% of those returned ballots must vote "Yes" for a traffic calming proposal to pass. Transportation staff have found that the 50% return requirement is a particularly difficult threshold to achieve and that some residents are choosing not to vote rather than vote a "No" if they do not support the proposal. This has led to only two out of five (40%) ballot proposals achieving the 50% return rate, while four out of five (80%) have exceeded the 67% approval rate. Over the last year, three ballot proposals have failed to reach 50% return rate, while two of them achieved over 78% approval. Preston's recommendation is to reduce the 50% return rate requirement for the neighborhood vote down to 33% in order to improve resident participation in the process and better serve neighborhood residents with regard to traffic calming. Preston also recommended lowering the 67% approval rate to 55%. Both measures should make it more possible to implement traffic calming for qualifying neighborhoods. ........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
