TITLE

Request authorization for the County Executive to enter into a contract between Whatcom County and Brown & Caldwell to conduct Phase 2 of the Lake Whatcom Total Maximum Daily Load (TMDL) Reassessment in the amount of $303,935

BODY

SUMMARY STATEMENT OR LEGAL NOTICE LANGUAGE:

Appendix 2 of the Western Washington Phase II Municipal Stormwater Permit requires that Whatcom County update phosphorus loading capacity targets for the Total Maximum Daily Load (TMDL) for Lake Whatcom. Phase I of this requirement involved the compilation of stream sampling data and the development of a Quality Assurance Protection Plan (QAPP) which lays out the steps and methodology for updating the model

Phase 2, the subject of this contract, will take data compiled in Phase I and begin model recalibration, water quality scenario modeling and interpretation of modeling results produced by the CE-QUAL W2 model
