<br /> <br /> <br /> <br />MEMORANDUM <br /> <br />TO: Jeremy Barnhart, Planning Manager <br /> <br />FROM: Rebecca Haug, Environmental Administrator <br /> <br />DATE: August 21, 2006 <br /> <br />SUBJECT: Oak Wilt identified at the proposed Uberty Heights Estates <br />Plat <br /> <br />Oak wilt is an aggressive disease that affects many species of oak trees, and is threatening the <br />urban and rural forests of Minnesota. Recendy, the Sherburne County Forester identified <br />oak wilt at the Liberty Heights Estates plat using aerial photography. <br /> <br />As a condition of plat approval, the developer should be required to do the following: <br />). NO pruning of oak trees between April 1 and July 1; if accidentally wounded, non- <br />toxic paint or dressing to wounds shall be applied. <br />~ The developer must hire a qualified tree inspector to determine the presence of any <br />oak wilt and/or develop an oak wilt control! prevention plan. <br />o If oak wilt is identified, remedies to control it must be provided to the city <br />for approval as well as the oak wilt control plan. <br />o All remedies to control oak wilt must be conducted in a timely manner. <br />). Developer must inform buyers of any active oak wilt known to exist on the property <br />and any oak wilt suppression work known to have occurred on the plat as a <br />condition of plat approval <br />). The above conditions should be required for all plat approvals. <br /> <br />It costs money to control oak wilt, but doing nothing can be much more expensive. Costs <br />of ignoring oak wilt include increased heating and cooling costs for homes, cost of additional <br />dead tree removal and decline in property value and quality of life. <br />
