a. Prevent impacts to water quality and stormwater quantity that would result in a net loss of shoreline ecological functions, or a significant impact to aesthetic qualities, or recreational opportunities.

b. Ensure mutual consistency between shoreline management provisions and other regulations that address water quality and stormwater quantity, including public health, stormwater, and water discharge standards. The regulations that are most protective of ecological functions shall apply.

c. Existing public stormwater management systems and facilities should be retrofitted and improved to incorporate low impact development techniques whenever feasible and as specified in Chapter 15.42 BMC.

d. Improving water quality is one of the primary goals within the restoration plan (Appendix B). The water quality improvement objectives should be considered and implemented into future watershed planning including prioritization and identification of retrofitting opportunities.

e. Drainage from single-family residences should not be tight-lined directly to or over shoreline bluffs or steep banks. Drainage, to the maximum extent feasible, should be designed or retrofitted to include water-quality measures that filter out pollutants common to single-family residences such as phosphorus-leaching vegetative material in roof gutters, fertilizers and pesticides and should be discharged at a point that does not prematurely erode the shoreline or the face or toe of said bank/bluff.

f. Boating practices on Lake Whatcom, Lake Padden and Bellingham Bay including operation and maintenance should be conducted in such a manner that prevents harmful substances from entering the water such as gasoline, two-stroke engine fuel, paint and wood conditioner and other boat related substances.
