MEMORANDUM
DATE: July 17, 1998
TO: The Honorable Mayor and Board of City Commissioners
FROM: James W. Shira, P.E.

SUBJECT: Traffic Signal at Maguire/Roberson
The attached letter from PEC describes the work that will be required to advance design and
construction of this signal ahead of the proposed construction of the Maguire Road widening.
The longest lead item will be acquisition of the needed right-of-way. To install a traffic signal at
this intersection, now or during the main widening project, additional right-of-way is needed to
place the traffic signal strain poles in their proper location. Even without widening Maguire
Road, a traffic signal cannot be installed without acquiring additional right-of-way because there
would not be adequate clearance from the traffic signal strain poles to the traffic lanes. The
additional right-of-way that is required for this signal installation would have been acquired
along with drainage parcels, in the normal course of the design and right-of-way acquisition
process.
By advancing the construction of this signal,we will have to begin acquisition of this right-of-
way now. If we must go through the complete quick-take process for all of the needed right-of-
way, the acquisition process could take three to four months to complete. During that time,
detailed design of the signal installation can be completed. If the right-of-way is acquired in
three months, construction of the signal could be completed within another month, and then
would have to flash for two weeks before being placed in full operation. From this date, we
believe the signal could be operational in four to six months.
The cost to construct this signal as part of the overall Maguire Road widening project is
estimated to be $60,000. By advancing the construction of the signal, we believe there will be
approximately $20,000 in additional "throw-away" costs, and $7,000 in additional engineering
fees. These costs are due to the fact that upon construction of the full intersection and road
widening project, traffic detector loops and pull boxes will need to be relocated,traffic signal

heads will need to be realigned on the span wires to line up with the new lanes, and signal
phasing will have to be changed. The engineering fees are related to preparation of two sets of
drawings and specifications, including those required to modify the signal to be constructed now
to the ultimate configuration. The benefit derived in exchange for this $27,000 cost is an
operational signal at this location in four to six months instead of twenty-four months.
We request that the City Commission direct staff to either begin work on advancing construction
of this signal, or leave it as part of the overall Maguire Road widening project.

Dear Mr. Shira:
Professional Engineering Consultants, Inc. (PEC) is pleased to present an engineering
proposal to advance the signalization of the Maguire Road/Roberson Road intersection.
Presently the roadway design for the section of Maguire Road at the intersection of
Roberson Road is in the 60-80% completion stage. The current estimate is to complete the
Maguire Road construction in approximately 24 months from the date the work is
authorized to begin.
PEC has been requested to provide additional information related to the possibility of
immediately signalizing the Maguire Road/Roberson Road intersection. We have reviewed
the existing roadway plans and the signalization can be completed in the following manner.
1. Design the signalization improvements immediately;
2. Develop a set of construction drawings and specifications for the signalization
improvements;
3. Develop legal descriptions of the property that the City must acquire for placement
of the poles and signal equipment.
4. Utilize one of the five existing continuing contractors to install the signals.
5. Acquire the needed property (negotiation or eminent domain) for signalization.
The acquisition of property is consistent with the existing Maguire Road plans.
Additional property is not required but the property will be purchased sooner than
previously planned.

The design and preparation of the construction drawings, specifications and property legal
descriptions can be completed within two (2) weeks. The property acquisition may take
up to three months to complete the appraisal and court filings for a "quick take" if
negotiations are not successful. Construction and installation of the signals can be
completed within one month and the signals will have to "flash" for two weeks before
being placed into operation.
Additional costs for engineering services will not exceed $7,000. Additional design work
includes the separation of the signalization design from the Maguire Road plans and the
development of a separate set of specifications and bid documents. We also estimate that
the advance of the signalization of Maguire Road/Roberson Road may cost up to $20,000
more than if the signalization was incorporated into the Maguire Road construction.
Very truly yours,
