MEMORANDUM
ITO: Don Ashworth, City Manager
FROM: Gary Warren, City Engineer
IDATE: March 5 , 1990
I SUBJ: Accept Feasibility Study for the Upgrade of Audubon Road
South of Railroad to Lyman Boulevard, Improvement Project
No. 89-18; Call Public Hearing
IImprovements to the north end of Audubon Road north of the
railroad crossing to Trunk Highway 5 were completed in 1989. The
II final wear course will be placed this . year. Similarly, the
City' s development district plan for Development District No. 2
included funding for improvements to the southerly half of
Audubon Road from the Soo Line Railroad south to Lyman Boulevard.
1 Since Audubon Road is a State-Aid road it was originally
anticipated that the upgrade would be funded through a percentage
participation utilizing State-Aid funds. However, as this is
I part of the development district as :shown on the attached map,
and recognizing the limited nature of- our State-Aid construction
funds, it is of considerable benefitrto the City to construct
II these improvements utilizing a combination of special assessments
and tax increment monies.
The feasibility study was authorized by the City Council on
I September 11 , 1989 and has been on hold basically due to the
changing nature of the -development plans in this area. Now that
the Redmond parcel and Lake Drive West ,project have been
1 initiated, the Audubon Road improvements plan can °be finalized.
As such, the attached feasibility study prepared by Howard,
Needles, Tammen and Bergendoff (aNTH) addresses the project
I scope. As noted, the segment of the roadway (Segment 1) from the
railroad tracks to Lake Drive West is proposed to be constructed
in an urban section with curb and gutter consistent with the
I roadway immediately to the north. The southerly segment (Segment
2 ) from Lake Drive West to Lyman Boulevard would be reconstructed
in a rural section and basically would require a bituminous
I overlay of three to four inches. Some minor vertical curve
improvements are anticipated to comply with State-Aid standards
in order to maintain the 45 MPH speed.

A trailway option has been presented in the feasibility study for
I constructing key elements of the City's rural trail network.
This is reflected in the exhibits in the feasibility study.
Specifically, cost estimates have been included for construction
' of a concrete sidewalk north of the railroad tracks along the
Audubon Court property and a bituminous trail south of the
railroad tracks along the westerly side of the roadway to Lyman
Boulevard. This will interconnect with the sidewalk constructed
' last year on Audubon Road from Trunk Highway 5 to Park Road. The
comprehensive trailway plan which is attached considers this link
as an element of the system network to connect with Lyman
' Boulevard.
In order to cross the railroad bridge the bridge abutment and
' pier caps will need to be expanded and a six-foot walk
constructed as an attachment to the bridge. There is not
sufficient bridge width to accommodate the trail without this
modification. This is included in the cost estimate.
' Sanitary sewer and watermain are proposed to be constructed on
Audubon Road to connect with the Lake Drive West proposed
' facilities and the sewer and water extensions from the area north
of the railroad tracks. Where these utilities traverse abutting
properties, a residential equivalent assessment has been proposed
for those properties. This is summarized in the proposed funding
' and assessments portion of the report and a detail preliminary
assessment roll is included in Appendix B. Approximately
$112,230 (18%) of the $629,500 project costs are proposed for
assessment.
It is therefore recommended that the City Council accept the
attached feasibility study as prepared by HNTB and call a public
hearing for March 26, 1990.

Manager's Comments: Funding of Audubon Road via tax increment,
south of the railroad tracks, has been considered since the
creation of the district - albeit not as quickly as currently being
' considered. Acceleration is primarily a result of Redmond/
Lake Drive proposals. This office concurs with the recommendation
of the engineer. However, the issue is whether sufficient TIF
monies exist. The answer to this question is dependent on two
factors:
Manager's Comments (continued)
March 5, 1990

- Tax Anticipation Estimates: The plan was completed
using estimated tax figures. Actual figures will not be
known for an additional year, but estimates that will be
within 5% will be known within the next sixty days. It is
the figures to be received within the next sixty days which
will be critical, i.e. we can tolerate a 5% error, but not
a 30%, 40%, or 50%; and
- Status of "A" or "B" Distribution Request: At time of
certification, the city requested that the district be
accepted as a "A" district under tax increment law. The
County Board did not act on this request leaving such to the
County Auditor. In layman's language, this request comes
down to a determination as to whether the fiscal disparities
distribution dollars will be available to the district or
not. That determination increases or decreases revenues by
37%. That difference alone determines whether funding is
available for this project.
As stated above, this office concurs with the engineer's '
recommendation with the caveat that whether funding exists will not
be known until the public hearing date or potentially later.
