Agenda Memo
September 19, 2017 Public Works Committee Meeting
II. Central Maintenance Facility Landscaping & Noise Mitigation
Direction To Be Considered:
Recommend City Council action regarding award of landscaping base bid and noise wall
alternate bid for Contract 17-21 (Central Maintenance Facility (CMF) landscaping and noise
mitigation improvements).
Background:
Phase 1 of the CMF renovations is substantially complete consisting of additional heated
vehicle storage and equipment bays, enlarged and updated service bays, free standing
utility building, material storage bins, brine building and tanks and salt storage building.
The construction of some of the new facilities relocated some operations upon the CMF
site, as well as placed facilities where no facilities had previously existed.
Some of the residents of Terra Glenn, the single-family neighborhood west of the CMF
site, have expressed concerns with the aesthetics of the new facilities or the noise
related to the operations. Staff have communicated with the residents and responded
to requests.
On December 20, 2016, at the Council Listening Session, Terra Glenn residents
addressed the Council with their concerns about the salt shed that was recently
installed at the CMF. Staff noted further discussions will occur in the spring regarding
landscape screening for the perimeter of the CMF site, including the area near the salt
shed, and that the neighborhood will be included in that discussion. The Council
directed the Public Works Committee to review screening options.
On May 18, 2017, an open-house meeting was held with adjacent neighbors to solicit
input and share site constraints in preparation for landscaping and wall design.
On July 20, a second open-house meeting was held with the neighbors to share the
preliminary landscaping plans, as well as details of Phase II of the CMF renovations.
Updates:
Landscaping
The landscape architects have completed the design of the landscaping improvements
along the perimeter of the CMF property. The plans were advertised and two bids were
received on September 6.
The low base bid of $50,970.00 was 12% above the Engineer’s estimate of
$44,922.50.
Agenda Memo
September 19, 2017 Public Works Committee Meeting
Funding for the landscaping improvements would be paid via various funds as
designated in the 2016-2020 Facilities Capital Improvement Plan (Project 1206).
If a contract is approved, landscaping would be completed in the fall, 2017.
Noise Mitigation
Staff has purchased "white noise" backup beepers to test their use on vehicles and
equipment at the CMF. This alternative noise mitigation effort was suggested by one of
the Terra Glenn residents. The backup beepers meet OSHA safety requirements. Staff
has determined that all vehicles with backup beepers would be appropriate for
replacement due to safety reasons, as well as noise aesthetics. The cost to replace all
existing backup beepers with "white noise" versions would be $12,000. Staff is
proceeding with acquisition and replacement of all beepers.
Soil borings provided design guidance for the further consideration of the installation of
a noise wall. An alternate bid for a noise wall was included with the landscaping plans
that were advertised for bids.
The low alternate bid of $186,000.00 was 6% above the Engineer’s estimate of
$175,000.00 for the noise wall.
The City Attorney’s office has reviewed Minnesota Statutes 429 (Special
Assessments) and is recommending that the City not finance a noise wall installation
through assessments to the neighborhood. Funding for the noise wall could be paid
via various funds as designated in the 2016-2020 Facilities Capital Improvement Plan
(Project 1206), although such funding for the noise wall was not anticipated and was
not budgeted accordingly.
If a contract is approved, a noise wall could be completed in the fall, 2017.
Staff have communicated this information with Dave and Amy Ryan, 3513 Birchpond
Road. The Ryan’s have been invited to attend the Public Works Committee meeting.
