LANDSCAPING/TREE PRESERVATION
Existing tree cover of the site is approximately 100% and consists mainly of oak, basswood, and
box elder. As part of the review of the Creekside subdivision, a 60' x 60' building pad and 20'
wide driveway was estimated for tree removal. If additional tree removal is done in excess of
these amounts, tree replacement shall be required pursuant to the tree preservation ordinance.
WETLANDS
An Ag/urban wetland is located in Outlot D adjacent to Lots 3 and 4. A 40 foot setback from the
wetland buffer is required for buildings on these lots. The wetland buffer shall average 10 feet in
width with a range from 0 = 20 feet. Wetland buffer areas shall be surveyed and staked in
accordance with the City's wetland ordinance. The City will install wetland buffer edge signs
before accepting the utilities and will charge the applicant $20 per sign.
