SUBJ: Authorize Feasibility Study for Street and Utility Improvements to Teton
Lane fran Lilac Lane south to Ashton Court and Lilac Lane west of Powers
Boulevard, in Association with the Development of the Donovan Property.
' LUR 91-1
Project No. 91-4
The segment of Teton Lane from Lilac Lane south to Ashton Court is a substandard
' city street that is currently barricaded at the intersection with Ashton Court.
I am sure you are well aware of the issues that arose and the history of events
that occurred during the development of the Curry Farms Addition that produced
the current status. This substandard street improvement was believed to be the
appropriate compromise since only one property owner, Natole, would be utilizing
that segment of Teton Lane for access. At the time, none-of the property owners
' adjacent to this portion of Teton Lane expressed any intentions of developing
their properties any time in the near future.
City staff has recently received and inquiry on the ten acre parcel, owned by
James Donovan, to the west of Teton Lane. In fact, the prospective developer
and his engineer have met with staff to display and discuss sane conceptual
development plans for the property. During our discussions, the developer was
informed that a development proposal for this property would require the impro-
vement of Teton Lane to current City standards and as a minimum, depending on
access configurations, would require improvement to the segment of Lilac Lane
' from County Road 17 and Teton Lane. In response, the developer has made a for-
mal request for the City to initiate a feasibility study for the improvement of
Teton Lane and Lilac Lane and has provided the City with a partial escrow to
confirm their intentions.
' A feasibility study for improvements to Teton Lane was prepared in 1988 by the
consulting engineering firm of William R. Engelhardt & Associates. The study
' was undertaken at that time in association with the Curry Farms Development. A
number of alternatives were suggested, one of which was employed and yielded the
present street situation.
' Given that there is now a proposal for the development of the Donovan Property
and based on the information and comments received from residents and other
associated parties following the previous feasibility study it would seen
' appropriate to reevaluate the street and utility needs of this area and prepare
an updated feasibility study for the improvements to Teton Lane and Lilac Lane.

Engelhardt & Associates are very familiar with the history and issues associated
with this street improvement and therefore, would be the appropriate consulting
engineering firm to perform this feasibility study. I
I have recently received a proposal from Engelhardt & Associates to perform this
updated feasiblity study. The cost to perform this service along with conducting
some needed survey work is estimated at approximately $5,000.00.
Therefore, it is my recommendation that the City Council authorize the
feasibility study for the street and utility improvements to Teton Lane and '
Lilac Lane conditioned upon the applicant/developer providing a total security
(letter of credit or cash escrow) in the amount of $5,000.00 to pay for the
study and that the consulting engineering firm of Engelhardt & Associates be
designated as the engineer on the project.
