Additional Notes <br />The Planning Commission brought up a couple questions pertaining to shoreland management at <br />their February 4, 2009, work session. Staff has additional information for follow-up, included <br />below: <br />• What are the DNR definitions for the lake classifications, particularly recreational <br />development lakes (i.e. Round Lake)? <br />The DNR definitions for lake types are as follows: <br />-Natural Environment Lakes usually have less than 150 total acres, less than 60 acres per mile of <br />shoreline, and less than three dwellings per mile of shoreline. They may have some winter kill of <br />fish; may have shallow, swampy shoreline; and are less than 15 feet deep. <br />-Recreational Development Lakes usually have between 60 and 225 acres of water per mile of <br />shoreline, between 3 and 25 dwellings per mile of shoreline, and are more than 15 feet deep. <br />-General Development Lakes usually have more than 225 acres of water per mile of shoreline <br />and 25 dwellings per mile of shoreline, and are more than 15 feet deep. <br />• How are residents able to determine the Ordinary High Water mark for their lake? <br />Although residents will need to have a surveyor determine where the Ordinary High Water mark <br />(OHW) falls on their property, the DNR has an on-line lake survey that allows people to search <br />for information by lake name and/or identification number. The URL to this site is <br />http:Uwww.dnr.state.mn.us/lakefind/index.html. Staff intends to provide a link to the survey and <br />a list of city lake OWHs on the City website. <br />Per the DNR survey, the 2007 (current) OWHs for lakes in Arden Hills are: <br />-Lake Johanna: 878 feet <br />-Lake Josephine: 884.4 feet <br />-Little Lake Johanna: Not listed <br />-Lake Valentine: 878.7 feet <br />-Karth Lake: 934.95 feet <br />-Round Lake: 890 feet <br />*NOTE: Marsden Lake is not recognized as a lake in the DNR lake survey. <br />City of Arden Hills <br />Planning Commission Work Session for .Hatch 4, 2009 <br />P: IPlanninglPlanning Casesl2009W9-003 Shoreland Preservation Ordinance 1030409 - PC report - Shoreland Update.doc <br />Page 3 of 3 <br />
