STREET IMPROVEMENTS (Continued)

Items that are considered in determining priority are water, sanitary sewer and/ or storm drain
improvements as these projects can be scheduled as complete reconstruction projects, or delayed so that
utilities can be constructed first. In some cases, streets falling into this category are recommended for 2”
overlay or slurry seal work to preclude further pavement deterioration until utility improvements can be
completed. An interagency agreement with Tarrant County provides for shared cost related to street
base, overlay, and slurry seal. The county provides labor and equipment and the City provides supplies.

Updates to the 1990 Thoroughfare Plan were made in the 2010 Comprehensive Master Plan. If the
pavement structure of the current street section needs rehabilitation exceeding the overlay process,
these projects take longer to complete.

Some streets which were rehabilitated or reconstructed over the past 10-15 years and were periodically
maintained through crack sealing continue to develop surface cracks. These cracks, if unsealed, can
destroy permanent foundation by allowing water to enter the subgrade, causing clay pockets to expand
and contract again during dry periods. Therefore, street projects recommend slurry sealing. Non-
recurring or one-time revenues should, to the extent possible, only be used for one-time expenditures
(expenditures not expected to recur and requiring future appropriations) to avoid future shortfalls.

Mill and overlay repair is less costly as the mill product can be used for recycled material on other projects.

WATER and SEWER IMPROVEMENTS

Water and Sewer improvements require removal of existing pipe, excavation to required depth,
approximately 6” sand below pipe, pipe, approximately 6” sand above pipe, 6” of road base, and 2” of
asphalt or permanent road base.

FUNDING LINES

The adopted budget includes appropriations for projects listed in the five-year CIP-Street program in the
general fund, street fund, and water sewer fund. As these projects are completed, the capitalizable value
will be moved to the Capital Improvements Fund. Costs are addressed on a project-by-project basis and
potentially funded from available fund balance in the Capital Projects Fund.
