2022 Gypsy Moth Special Assessment Districts

Summary:
In response to numerous resident requests, the Village of Lake Isabella has created a process for residents to petition to have their property included in a Special Assessment District to fund an aerial spray targeting gypsy moths in the spring of 2022. This spring the community saw large areas where gypsy moth caterpillars fed on leaves of hardwood trees. Gypsy moth outbreaks started occurring in Michigan in the 1980s. Since then outbreaks have become a common nuisance, especially in residential areas. The caterpillars feed on the leaves of oaks, aspen, apple, and similar trees from late May until early July.  It is during this period that an aerial spray can be conducted to treat an infestation. 

After feeding for several weeks, the caterpillars will then spin a reddish-brown cocoon in July and pupate for one to two weeks. Adult moths then emerge from these cocoons usually around the end of July. The moths live only for a short period of time before the females lay a new egg mass.

IMG_2030Egg masses are typically found attached to trees, downed limbs, and on rock piles. They remain in place from the time they are laid in August and persist after the caterpillars hatch in May. They are typically shaped in a teardrop of 1 to 2 inches long. Egg masses are a yellow-brownish color and have a felt-like appearance. Destroying egg masses is the first step in preventing a problem in 2022. For each mass that is destroyed that is potentially several hundred caterpillars that will not be a problem in the spring. This fall please inspect surfaces on sheds, garages, landscaping, fencing, and woodpiles in addition to your trees. 

If the Council moves forward after the January Public Hearing, the next step is creating a Special Assessment Roll to cover the costs of treating areas within the District. Another Public Hearing would then be held in March where all properties where an assessment is proposed will have the right to object. The process of determining where to create a Special Assessment District will balance areas where egg masses are identified and where there is sufficient interest from property owners to fund a treatment. Any assessment levied would then be collected on the property’s 2022 Village tax bill.

Project Cost Example:
The example provided below is to illustrate the structure of a possible Special Assessment District. For the purpose of this illustration, $60/acre was used as the cost to spay, 100 acres is the illustrative district size, and there are 128 parcels in the example. Actual costs will likely vary from these numbers based on the actual spraying costs and the number of parcels included in a special assessment district.

Cost/Acre $60
Acres in Special Assessment District 100
Treatment Cost $6,000
Publication & Mailing Costs $400
                                              TOTAL COST: $6,400
Parcels in District Sharing Total Cost 128
Cost per Parcel $50
