If pipe material and age are available, they will also be provided. This data will be
provided in GIS format if possible.
b. Provide available data pertaining to water demand data, current CIP information,
street locations, and available parcel maps. Whenever possible, this data will be
provided in electronic format. As much as possible, data will be provided in ArcView
compatible format.
C. Examine all alternate solutions, studies, reports, sketches, proposals and other
documents presented by Engineer;

ADDENDUM TO EXHIBIT B
Engineering Services
The purpose of this project is to provide support to the City for running "what if
scenarios using the most recent water model (WaterGEMS model platform). The existing
and future conditions models have been updated as of August 2015. The services shall
include the following tasks:
1. The model will be updated as appropriate to reflect additional constructed
infrastructure as provided by the City. The model will then be run to evaluate
specific additional loads/demands to the water utility systems as specified by the
City in writing. Periodically, the updated model may be provided to the City, if
requested.
2. Engineer will evaluate specific development situations as directed by the City and
provide a recommendation as to whether existing infrastructure can support the
development and, as necessary, recommendations regarding the infrastructure
required to allow for the proposed development.
3. An email and/or informal memo will be prepared and sent to the Project Manager
outlining the request for evaluation and results of the evaluation. The Project
Manager will distribute to the City as needed. For evaluations that involve multiple
development areas, as opposed to one or two individual development lots,
associated CIP maps and/or cost tables will be updated as directed by the City.
The overall 10 -year CIP map will be updated to reflect major infrastructure
required for the area. As needed or requested, preliminary/planning level cost
estimates will also be prepared and provided along with the updated 10 -year CIP
map.
4. Engineer will also indicate in the email/memo if the plans for specific
developments meet the criteria established for determining water demands based on
the future land use plan. This information will help the City determine if there are
significant deviations from their CIP.
5. Services will also include periodic conference calls or, if needed, meetings with the
City to discuss evaluations and implications of development scenarios. Engineer
will revise data as directed by the City based on these discussions.

Consider executing Supplemental Contract No. 1 with CDM Smith for the 2014 Water
Master Plan Update Project.
It has become necessary to retain CDM Smith, the engineers who developed the city's
most current water model, to provide additional modeling tasks as -needed. This
supplemental agreement would enable the City to request the engineers to run different
scenarios or to revise the model as need be for various circumstances that routinely
arise. These circumstances include modifications to the water distribution system or
how the system is operated, or how a proposed development might impact or be
served using existing or modified infrastructure. The agreement will allow the City to
obtain water model assistance as it arises. This task will be included in the next Water
Master Plan contract so that no supplemental agreements would be necessary in the
future for this type of service.
Staff Recommends Approval.
