The ordinance amendment adopted Chapter 4 of the Washington County Development Code with exceptions, and outlined changed standards. Under Minnesota Pollution Control Agency (MPCA) requirements, the City is also required to submit changes to the MPCA for review along with a required checklist and list of differences between Minn. Rules Chapter 7080 and 7081 and the City Code. Upon compiling this checklist and list of differences, Staff found that a number of definitions within the City Code were not consistent with Minn. Rules and has prepared definition amendments to obtain consistency. The MPCA has reviewed Chapter 51 and the proposed definition amendments and has found no issues with either.

PROPOSAL DETAILS/ANALYSIS: Staff has prepared amendments to these definitions which accomplish the following: • Repeal definitions which are not found elsewhere within the Code. • State that certain definitions shall not apply to Sections 51.001-51.005. Sections 51.001- 51.005 adopt Chapter 4 of the Washington County Development Code, which sets forth definitions to which the chapter applies. FISCAL IMPACT: None. OPTIONS: • Approve the proposed ordinance as proposed. • Amend the proposed ordinance and approve. • Deny the proposed ordinance. RECOMMENDATION: Staff respectfully requests that Council, as part of tonight’s Consent Agenda, approve the ordinance amending definitions to Chapter 11: Definitions pertaining to Sections 51.001-51.005: Subsurface Sewage Treatment Systems Waste as proposed. If removed from the Consent Agenda, Council may adopt the proposed ordinance with the following motion: “Motion to adopt Ord 08-171 amending definitions of Chapter 11: Definitions pertaining to Sections 51.001-51.005: Subsurface Sewage Treatment Systems Waste.” Staff also recommends that the Council authorize summary publication of Ord 08-171. “Motion to adopt Resolution 2017-022 approving summary publication of Ord 08-171.” ATTACHMENTS: • Ord 08-171 • Resolution 2017-022 CITY OF LAKE ELMO COUNTY OF WASHINGTON STATE OF MINNESOTA ORDINANCE NO. 08-171 AN ORDINANCE AMENDING CHAPTER 11 OF TITLE I: GENERAL PROVISIONS OF THE LAKE ELMO CITY CODE SECTION 1.
