Consider executing Supplemental Contract No. 2 with Kasberg, Patrick&Associates,
LP for the Dove Creek Drainage Improvements Project.
In April of 2014, the City completed a drainage analysis for the southeast portion of the
Dove Creek neighborhood to determine the feasibility of implementing drainage
improvements to reduce the frequency of street inundation and property flooding that
has been experienced during intense rain events. Based on the results of this analysis,
the City then identified funding in order to hire a consultant to design improvements that
would improve the drainage in this area.
In December of 2014, the City Manager approved a Contract for Engineering Services
with Kasberg, Patrick &Associates, LP for the Dove Creek Drainage Improvements
Project. This Engineering Services Contract provided plans, specifications and related
documents necessary for the City to install the aforementioned improvements.
In May of 2015, the City Manager approved Supplemental Contract No. 1 in the amount
of$8,005 for bidding and construction phase services.
During a site visit with a resident who had some concerns about the current project in
the Dove Creek area, substantial erosion was identified downstream. After
investigation by City staff, it was determined that the erosion was compromising the

integrity of an existing wastewater line, and it would be more beneficial and cost
effective to address this problem with the current project. This Supplemental Contract
No. 2, in the amount of$5,485, will address these concerns and bring the total contract
amount to $42,455.
Staff recommends approval.
