• AGENDA ITEM V. G STAFF ORIGINATOR: Jeff Smyser P & Z MEETING DATE: July 12, 2000 TOPIC: PUBLIC HEARING (continued): Ordinance 09 -00 Tree Preservation Ordinance BACKGROUND We have received information that allows staff to analyze a hypothetical development with regard to the requirements of the draft tree preservation ordinance. The site analyzed is about 7.7 acres including road right of way and 17 lots. We have completed the exercise of reviewing the development plan, which resulted in the following: • total tree cover 4,000 caliper inches • tree loss 1,000 caliper inches • tree loss 25% of the total tree cover. • at 25% loss, replacement requirement would be 50% of lost trees • replacement: 500 caliper inches • We then attempted to estimate the cost of this replacement The Environmental Specialist assembled the following data: 250 red oak trees of 2" diameter 286 green ash trees of wholesale planted $119 each, $29,750 total $238 each, $59,500 total balled & burlap $29 each, $8294 total $58 each, $16,588 total 1.75" to 2" diameter potted Though there are more options than this, this provides a good range from an upper to a lower end cost. Assuming a 50/50 variety of trees, the total replacement would be about $38,000. If this exercise indicates a typical expected level of loss and cost and we judge it is too high a cost, we should examine the replacement percentages. If this level of loss and cost is not typical, we would be examining an exceptional piece of land and should not be making policy based on such an example. Some exception could be written into the ordinance to account for excessive cost situations. To see if this is an unusual piece of land, we are attempting to examine the tree cover in • Lino Lakes using the environmental inventory. If we can use the inventory to compare
