• • DANE COUNTY DEPARTMENT OF PLANNING & DEVELOPMENT SUPPLEMENTARY STAFF REPORT Petition 7287—Fish Lake Development Corp. Date of report: 9/2/98 I. ANALYSIS OF EFFECT OF CHANGE IN WATER LEVEL OF FISH LAKE The Zoning Division has evaluated the effect of the new ordinary highwater mark of Fish Lake on Petition#7287. According to the Department of Natural Resources, the water level of the lake has risen by 2.24 feet since 1993. The DNR has established the new ordinary highwater mark elevation for Fish Lake at 859.25 feet above mean sea level, compared with the previous mark of 856.45. Based on field investigations of the Summer Place on the Lake site, Zoning Division staff estimate that this change would result in a horizontal loss of between 25 and 40 feet of shoreland on the east shore of Fish Lake. This means that the depth of the condominium units along the shore (numbers 1 through 31) has been substantially reduced. Based on this information, the Zoning Administrator has determined that the mobile homes currently located on Units 5, 7 and 10 have now become non-conforming structures. Under the county zoning and shoreland ordinances, such structures are allowed to remain, but cannot be expanded or improved beyond 50% of their current assessed value and must be brought into conformity if they are ever substantially damaged. The Zoning Administrator estimates that approximately six to eight of the vacant condominium units have been so reduced in size that placing a 76' mobile home and a 12' deck will likely be impossible without violating zoning setback standards. Detailed studies of individual units will be necessary to determine the allowable building footprint for each unit. II. SUGGESTED CONDITIONS OF APPROVAL In light of the rapidly changing water level of Fish Lake and the potential impact of the proposed development described in the original staff report for Petition 7110, the committee may wish to consider adopting the following findings of fact and conditions: FINDINGS OF FACT: Regarding Petition # 7287, seeking to remove deed restrictions limiting the use of property in the Town of Roxbury to a seasonal mobile home park use, the Zoning and Natural Resources Committee finds the following: 1. Conversion of the property from seasonal to year-round use represents a significant change in the intensity of the land use. 2. Year-round use of the property is likely to lead to more and larger permanent structures, greater impervious surface area and significant changes in the hydroloy, vegetation and character of the immediate shore area. 3. Without additional safeguards, these changes to the character of the immediate shore area would likely result in degraded water quality, increased risk of erosion and water pollution,
