RE: Amendment to Water Distribution System Hydraulic Model and Planning Study Contract
CH2M HILL
In August of 2010 CH2M Hill was awarded a contract to complete a Water Distribution System Hydraulic
Model and Planning Study for the water system. The Study Scope included the following elements:
• Population and Service Area Growth Projections
• Water Demand Forecasts
• Analysis of Existing Water System Facilities
• Hydraulic Distribution System Model
• Water System Evaluation and Improvement Analysis
• Recommendation for Implementing Improvements
Additional work was required in the areas of fire flow analysis, future land use planning and review, and
hydraulic demand node modification. This additional effort provided important information that will be
used for future analysis and planning for water infrastructure improvements.
The original study agreement was for $ 170,100.00. This amendment is for $38,000.00 bringing the total
project cost to $208,100.00 Funds are available in the 2012 Water Utility operating fund budget to cover
the additional costs.

including engineering services, may be approved by the City Manger without the use of formal sealed
quotes. In accordance with 12 -10(E) of the Code, I am hereby submitting this report regarding this
contract amendment.
