COUNCIL ; PWING To: Mayor Butler Mark Bernhardson, City Administrator -2 Orono Council Members �� ' From: Jeanne A. Mabusth, Zoning Administrator CITY OF MONO Date: August 21, 1985 Subject: a) #852 Stanley Gregory, 1410 Shoreline Drive - Conditional Use Permit - Installation of decorative pond - second review by Council - tabled at 7/22/85 meeting pending staff's resolution and recommendation for procedurally dealing with the alleviation of designated wetlands. b) #927 Stanley Gregory, 1410 Shoreline Drive - Multiple Variances for Swimming Pool a) #852 Staff recommendation regarding construction of decorative pond - alteration and installation of wildlife pond to be reviewed at a later meeting. Review of application since last reviewed by Council - Staff met with the following individuals on August 1 to discuss the total Gregory application: Mr. & Mrs. Gregory Greg Kopischke, Applicant's Engineer/Planner Glenn Cook, City Engineer Jim Mahady, MCWD Joel Settles, U.S. Soils Office Dr. Richard Hanson, FWBI It became apparent early into the discussion that the decorative pond proposed was viewed as minimal in scope and considered to have little if any negative impact on water quality or quantity. Retention is improved, aeration will preserve water quality. The subject area is not a wetland but a retention area - runoff flows directly from area out to lake via southern culvert. The open pond at a depth of 4 feet will now serve as a sediment trap - ridding runoff of the heavier sediment particules. Currently, severe rainfalls could permit the heavier or larger sediment to run directly into the lake. The "experts" see no problem with allowing independent construction of the decorative pond as long as the following is addressed: 1. The question of the maintenance of the desired water level must be resolved. Does the applicant plan to pump water from the main lake or install an independent well. They advise that droughts or dry periods will effect the water level of the pond constructed at the 929.4 elevation. 2. Plans for the temporary overflow outlet to the southern culvert must designate elevation of outlet, channel construction, cross pro- file of channel (banks to be at 7:.1 slope (horizontal :vertical) desig- nated to encourage return of vegetation. Channel to northern wetland will not be constructed until wildlife pond alteration is resolved.
