RECOMMENDED ACTION (Motion):
Staff recommends the City Commission approve the first reading of Ordinance No. 15-1006, adopting amendments to the Oregon City Municipal Code Chapter 13.12, Stormwater Management.

· Preventing water runoff generated by development from exceeding the capacity of downstream stormwater facilities;
· Reducing stormwater runoff rates and volumes, soil erosion and pollution, wherever possible, from developed and developing lands;

· Maintaining the integrity of stream channels for their biological functions, as well as for drainage and other purpose.
