Preliminary
Belt Line Road Street Assessment Program
The street assessments for the Belt Line Road Improvement
project have been prepared by three different methods. These
three methods are summarized on the next two pages for
comparison. The results have been tabulated for both a 6-lane
and a 4-lane project.
Method A, as shown in the table, is based on assessing the
property owners for the total project cost that is assessible
without deducting the funds appropriated by Dallas County from
that figure. The gross cost to the City using this method
includes all non-assessible items (ie., landscaping, street
lights, and traffic signalization), 10% of the paving and
engineering costs and all non-recoverable assessments (ie.,
Public R.O.W.'s and other non-assessible property). The net
total cost to the City is found by deducting the funds
appropriated by Dallas County from the City's gross cost for the
above items mentioned.
Method B is based on assessing the property owners for the net
total project cost that is assessible which is found by
deducting the funds appropriated by Dallas County from the total
project cost. The gross cost to the City using this method is
based on the sum of the costs for all the non-assessible items,
10% of the paving and engineering and all non-recoverable
assessments.
Method C is based on deducting both the funds appropriated by
Dallas County and the 1984 bond funds originally estimated for
this project from the total project cost to arrive at a net
figure of which is to be accounted for through street
assessments. Since the net figure accountable from street
assessments is a fixed figure, the assessment to be applied is
directly related to the recoverable assessments. Therefore, the
actual linear footage which is recoverable is what determines
the assessment rate per front foot. The net total cost to the
City using this method is the 1984 bond funds originally
estimated for this project (ie. $3,660,000.00).
In all three methods, the front footages are the same. The
total frontage length for this project is 17,100 linear feet.
The recoverable assessed frontage with DP&L's frontage included
is 16,710 linear feet. The recoverable assessed frontage
without DP&L's frontage included is 11,962 linear feet.
