CITY COUNCIL WORK SESSION Topic Report: Village of Sunfish Lake Consider Request 'of Developer to Alter Tree Preservation Plan By: Steve Jankowski, City Engineer Background: Grading for the Village of Sunfish Lake was initiated after tree preservation areas were identified and protected consistent with the approved tree preservation plan. At this point gading is. proceeding toward completion and the developer is requesting consideration for altering 1)~ree areas of the tree preservation plan. These areas are illustrated in the three exhibits prepared by Loucks Associktion which are attached to the case. The developer has annotated his reasons and comments on each area exhibit. Staff will have photos of the trees proposed for removal at the meeting. Staff offers the following comments on each area as follows: Area A · The grade from the rear of the house may be flattened to 1%, however, this will only save 2 to 2 V2 inches of fall. · The fingeriike incursion into the southeast comer of the tree preservation is not necessary. The stormwater pipe has been installed without any tree loss. · Alternative to encroaching ~nto the tree preservation area include: (a) Creating a rear yard depression a d raining through a yard d rain t o t he e xisting catchbasin near lot 7 (b) Raise the elevations of Lots 2 through 7 (other lots in this development have elevations 1 foot higher relative to the road) (c) Change walk out units to look out units or to the type of walk out units anticipated in Blocks 1 and 2. Area B The area of remaining trees appears to coincide with the northerly edge of the house pad on Lot 5. The seven-foot high retaining wall will require a minimum of eight feet from the face of wall at the toe to the rear of the wall at the top. It doesn't appear that tree impact can be avoided without the loss of Lot 5. Staff would suggest that the building pad for Lot 5 be staked prior to any tree removal so that it can be minimized. · The grade, difference between 146th Avenue and the area to the south is 5 to 5.5 feet. A 4 to 1 l~ackslope would require about 25 to 30 feet of trees to be cleaned behind the south curb line. The developer shows 45 to 50 feet beyond the curbline (based on the sca[e) A retaining wall could reduce this impact.
