Lowell Park Landscaping PlanTRANSCRIPT
MEMORANDUM
To: Mayor and City Council
From: ~ Shawn Sanders, Director of Public Works
Date: September 11,2015
Subject: Lowell Park Landscaping
DISCUSSION:
A few months ago the City was approached by volunteer to design a tree plan for the north Lowell Park area and the newly constructed trail from Mulberry Street to Laurel Street. A plan was presented to Council (attached) in August that showed a four different types of trees in this area which include, 21 Red Buds along the trail, 10 Red Maples in the circle at the east of Mulberry, 4 Pin Oaks in Mulberry Point and 9 White Oaks in the park from Mulberry to Myrtle Street. In looking at the plan, staff decided to delete 4 of the maple trees in the circle, because it was thought that spacing was to close for these trees and to only plant 11 of the Red buds because of some utility work remaining Staff then received quotes from two vendors to furnish the trees which then would be planted by volunteers. The low quote for the trees was submitted by Bailey Nurseries, in the amount of $3956.90 and was presented to Council for approval at the last City Council meeting.
In the following days, staff was asked to bring this item back to Council for further discussion.
Since the meeting there have been a few comments on the plan regarding location and quantity of trees. The tree plan as presented can incorporate changes such as reducing the amount of trees, the type of tree and location at any time up until the trees are actually planted. In fact, tree locations will change due to the irrigation system, utility and electrical lines that exist in the park today.
Also, an area resident through the Friends of Parks has inquired about donating $745 towards the tree planting project as a memorial to their spouse.
It is proposed that trees would be planted the weekend of September 19th
ACTION REQUIRED
Council have a discussion on the project and provide some direction to staff on how to proceed and also to consider the donation of $745 towards the planting of the trees in the park.

A very hardy selection of the popular red maple from northern Minnesota, this shapely shade tree features brilliant red fall color and showy red flowers along the branches in early spring; intolerant of alkaline soils
Ornamental Features:
Northwood Red Maple has green foliage which emerges red in spring. The lobed leaves turn an outstanding red in the fall. It features showy red flowers along the branches in early spring before the leaves. It produces red samaras in late spring. The furrowed silver bark and brick red branches add an interesting dimension to the landscape.
Landscape Attributes:
Northwood Red Maple is a deciduous tree with a shapely oval form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition .
This is a relatively low maintenance tree, and should only be pruned in summer after the leaves have fully developed, as it may 'bleed' sap if pruned in late winter or early spring. It has no significant negative characteristics.
Northwood Red Maple is recommended for the following landscape applications;
-Shade -Accent
