CITY OF FOREST HILL

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
could 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.

Some streets are recommended on the 1990 Thoroughfare Plan for upgrading from Local to Collector. If
the pavement structure of the current street section is in need of 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 reoccur and requiring future appropriations) to avoid future shortfalls.

A 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.
