Implications
Exceeding standards for Turbidity Total Suspended Solids (TSS) Phosphorus (P)
Lower (older) portion of the watershed lacks infrastructure needed for water quality
Expectations“Impaired” listing for
TurbidityPhosphorus
Active retrofitting lower creek
Creative infrastructure/close coordination with City
