Box 147 1 Chanhassen, MN 55317 Re: Boulevard Planting Proposal I Dear Ms. Olsen: 1 This letter proposal responds to your request for assistance in preparing plans and specifications for boulevard plantings. We understand the project areas would include Audobon Road from Arboretum Boulevard south to Heron Drive, and Kerber Boulevard I from Powers Boulevard Southeast to near Coulter Drive. Each of these roadway's boulevards pose differing opportunities and constraints for potential tree plantings. 1 Therefore, each of the two segments will be treated consistent with the area's abutting land use, topography, utility constraints, available right -of -way, and so on. I The following scope of services identifies those tasks that we feel are appropriate in completing the assignment. I SCOPE OF SERVICES Task 1: Basemap Preparation 1 The boulevard areas that will receive landscape plantings have basemaps of varying quality and scales. These basemaps were provided as a part of the street's original I construction documents. This task will establish basemapping for the boulevard areas of similar format such that a set of construction documents can result. The City of 1 Chanhassen will provide reproducible street construction basemaps for reformatting by Barton- Aschman. Task 2: Field Review I Barton - Aschman will conduct on -site field review for each of the boulevard areas, after the basemaps have been prepared, to become better acquainted with each area's physical 1 characteristics. In addition, inconsistencies with the prepared basemapping will be noted and revisions made if possible.

Task 3: Conceptual Landscape Plan 1 A graphic concept plan that portrays proposed locations for plantings will be completed. 111 The concept will be formulated from information gained on the basemaps, field review, and input from city staff. Tentative tree locations and intended species will be portrayed. Preliminary cost estimates will be arrived upon for review, comment, and I approval by the city. City staff will be responsible for reviewing the concept and obtaining necessary City I Council approvals.
