Re: AMENDMENT No 1
COFW Project 01068, Cedar Breaks Storm Drain Extension
Mr., Perkins,
Originally, the Cedar Breaks scope was to extend the existing storm drain from the southwest
end of Cedar Breaks Drive to the west end of Mesa Verde Trail. When survey and SUE were
conducted, numerous utility conflicts were revealed. These conflicts, along with an existing
concrete roads ayY made the preliminary engineer 11 s estimate approximately $583,000. At the
30% review, it was, determined that we should investigate the possibility of using underground
,detention and/or trench drains, as a means of reducing flooding in the Cedar Breaks area., A
prelimi�nary analysis using NCTCOG contours indicates that the HOA lot on Starwood Drive has
adequate elevation to accommodate underground detention. Additionally, a preliminary estimate
from Contech was $100,000 for the installation of their Storm Trap system. However, detailed
survey and SUE are required to conduct a full design. The initial survey and SUE only extended
to the outlet of the concrete flume. It is assumed that the ground water will be below the
detention, and this is supported by geotechnical testing in the area that indicated no
groundwater to a depth of ten feet., An additional option is to route the storm water to the
existing storm system in Basswood Boulevard by installing an Inlet at the top of the concrete
flume and tying It to the, back of the inearest inlet on Basswood. Finally, instead of extending the
existing Cedar Breaks storm drain, trench drains may be installed to route the water with
minimal impact to existing utilities and roadway pavem�ent.,
Due to the change in scope, MULTATECH is requesting an amendment to our current contract
to cover the additional expense of survey, SUE, and geotechnical testing for the proposed
detention area, the existing', concrete flume, and the adjacent streets (Basswood Boulevard and
Starwood Drive) to determine if the runoff can be routed to underground detention using
Contech or ADS detention systems or if'the water can be routed to the Basswood storm drain
system. These options will be taken to the 30% design level. If it is determined that Contech or
ADS systems are feasible for installation under the H:OA lot on Starwood Drive, it is anticipated
that the remaining design work can be completed within the remaining budget of the original
contract. This wound be due to reducing the project area and eliminating the utility conflicts.
Contech or ADS would design their product for the site at no additional cost to the City. If either
the Basswood storm drain or Cedar Breaks, trench drain system is selected, additional
engineering design services will be required as listed bel�olw.
