Oak Wilt Grant + � CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR ACTION CITY COUNCIL MEETING DATE: June 6, 1995 AGENDA ITEM: Oak Wilt Grant AGENDA SECTION: New Business PREPARED BY: Bud Osmundson AGENDA�� City Engineer/Public Works Director � � ATTACHMENTS: Application, Maps & Other Info APPR�VED BY: The City has been contacted by the Minnesota Department of Natural Resources, Division of Forestry (DNR) for interest in participating with the DNR in the Minnesota Cooperative Suppression Program for Oak Wilt. Mr. Tom Eiber from the DNR discussed the Oak Wilt Program with myself, Mark Joosten the City Forester and Lacelle Cordes, Park & Rec Department. The City has received a number of calls from residents regarding Oak Wilt. The Program works on a 50% cost share agreement with the DNR. The Program that Staff is suggesting and which is used by many cities does not actually include any City costs except some Staff time. The City utilizes residential payment for half the cost of the treatment of the diseased trees. The purpose of the Program is to coratrol Oak Wilt in the City of Rosemount, and to educate the Community of the problem and to promote a healthy environment to all citizens. The DNR has 510,000 available for the City residents who wish to pay 50% of the cost of the treatment. There are a number of "Shade tree professionals" who have the expertise and equipment necessary for treatment of the Oak Wilt disease. The main treatment is to actually plow a 48" deep furrow around the drip line of the infected tree. Oak Wilt is passed from tree to tree through the roots and this process cuts off the co- mingling of the roots and therefore the Oak Wilt is not passed on further. The initial Staff time will include mailing of information to a targeted area, then receiving calls and directing the residents to the vendor who would perform the treatment. Mark would be available to answer specifics if needed. The initial target area is the northwest corner, including Country Hills, Amberwood Estates and Danbury Way neighborhoods. More information will be provided at the Council meeting. Staff recommends the authorization to proceed with the Program.
