<br />R~ d nti~ Commercial Street Improvement Projects
<br />On residential street improvement projects which include Easy, Mossy,
<br />Willow View Road, Plainbrook Road, Lemon Lane, North "P", Battleview
<br />Drive, and Flintrock Drive, we recommend, as alternative 1, a two
<br />coarse surface treatment, 6" limestone base, and 6" lime S:~,abili.zed.
<br />subgrade. .Alternative 2 is a two coarse surface treatment, 8" calcium
<br />sulfate base, and 6" lime stabilized subgrade.
<br />Although the residential street projects are within original budgeted
<br />funds, only two alternatives are given because the overall project,
<br />which includes residential and commercial, will be over the original
<br />budget.
<br />The.following is a. cost comparison for the two alternatives for the
<br />above mentioned residential streets:
<br />Alt. 1 Alt. 2
<br />Easy Street 24,375 23,605
<br />Mossy Street 19,638 19,007
<br />Willow View Road 46,512 45,137
<br />Plainbrook Road 49,614 48,159
<br />Lemon Lane 65,535 62,135
<br />North '.'P" Street 44,519 43,052
<br />Battleview Drive 29,796 28,886
<br />Flintrock Drive ~20~,021 19,269
<br />Total 300,010 289,250
<br />The commercial street improvement projects include the following streets:
<br />West Polk, West "G", North 17th, West "F", West "E", and West Adams. The
<br />alternatives were similar for all streets with the exception of West "E".
<br />Mr. Smith recommended an alternative of reinforced concrete on this street
<br />because of the heavy traffic loads. It is our suggestion that this year we
<br />use the set of standards used in the. past and choose from the alternatives
<br />recommended by staff. This will result in savings of dollars and allow more
<br />study into the change of policy of constructing reinforced concrete streets.
<br />For all commercial streets with the exception of West "E", alternative 1
<br />would consist of 12" asphaltic concrete, 8" limestone base, and 6" lime-
<br />stabilized subgrade. Alternative 2 would be 12" asphaltic concrete surface,
<br />10" calcium sulfate base, and 6" lime stabilized subgrade.
