City Manager Re: Traffic Calming Improvements
at SW 67 Ave /SW 64 St Intersection
Request No. 1:
Traffic Calming Improvements at SW 67th Avenue and SW 64th Street Intersection.
Action Taken:
As requested, we have been coordinating with the County staff to make sure the radii
of the intersection is curbed and that concrete pavers are installed in the intersection.
Three weeks after our request, the County staff in charge of the project finally
responded that they don't have funding for our request; however they will allow us to
fund and continue the construction.
In attempt to take over the construction we have secured the attached proposal for
$ 112, 018.69 for the construction. See attached project detail from our Public
Works staff. Since we do not have enough funds for the construction, we are
coordinating with County staff to share the scope of work and cost. I have asked staff
to prioritize this coordination with the County.
Should you need additional information on any of the issues above, please do not
hesitate to contact me.

Subject: Traffic Calming Improvements at S.W. 67th Ave. /SW 64`h St. Intersection
Date: July 14, 2008
The intent of this project is to provide infrastructure improvements at the intersection of SW 67th
Avenue /SW 64th St. The major improvement will consist of installing vehicular brick pavers at
the above referenced intersection to work as a traffic calming device. The work will also include
milling and resurfacing, construction of concrete crosswalks and small portions of sidewalk and
curbing of the radii. The only contracting mechanism available at this time to perform the work
immediately, would be to award a construction contract to Homestead Concrete & Drainage,
Inc. by "piggybacking" on their existing contract for Church Street Improvements Phase IV. By
using the "piggybacking" method (using older prices), the city will only save approximately
$11,250.00, when you compare the previous contract unit price for brick pavers
at $50.00 /S.Y. versus today's estimated unit price at $80.00 /S.Y. The total cost of 'the
improvements is $112,018.69 as shown in the attached cost proposal submitted by Homestead,
Concrete & Drainage, Inc. Please note that funding may not be available to complete the above
referenced improvements and may compromise current funding available for our Capital
Improvement Projects.
