2. Water Supply Planning
Ash Hammerbeck, Project Manager summarized previous work session discussions regarding ground
storage water tanks and water tower storage units. Project Manager Hammerbeck outlined the
geotechnical report findings indicated suitable soil at the proposed location for both tower and ground
storage water supply facilities, noted suitable findings for the water treatment facility at proposed site,
reviewed low ground water finding, and noted clay soils will likely require a sump operation. Council
and Project Manager Hammerbeck discussed diameter dimensions of ground and tower storage, and
comparisons. Project Manager Hammerbeck reviewed the infrastructure considerations necessary for
pump stations from the well, to the treatment facility location, to the underground water storage option
or water tower option. Council discussed water tower locations. Council reviewed land availability
options for water tower, site feasibility of soil and elevation suitable for a water tower, and components
necessary for operational processes of a water tower. Council discussed resident comments and
concerns of industrial land use and an additional infrastructure burden of a water tower within the
same area. Council discussed location option of a water tower structure on an alternate parcel. Public
Works Director Mattson summarized engineering factors involved in selecting an alternate and
feasible land parcel location. Council requested a utility billing finance cost analysis to calculate
modeling capital costs necessary. Council and staff discussed future water storage needs, difficulty in
securing new water storage locations, and community agreement. Council noted interest in a different
property and requested staff to pursue land options with the landowner. Council discussed location of
water tower in relation to residential need and costs associated with land acquisition and infrastructure
costs. Council noted a preference for water tower location separate from residentially zoned areas.
Project Manager Hammerbeck noted importance of a land purchase by fall of 2022. Council and staff
discussed savings and efficiencies of working with developer on infrastructure, credit for land as park
dedication upon development, and recapturing some costs through trunk fees. Council directed staff to
review an alternate parcel site for a water tower location, to review design options, and to review with
Council at January meeting. Project Manager Hammerbeck presented options for different
architectural styles of treatment facilities, noted incorporation of an aeration tower in the water
treatment facility for organic treatments, slope versus pitched roofs, and brick building material to
soften the aesthetics of the facility. Council discussed incorporating a modern grain silo, copper roofs,
and cupulas to maintain Corcoran's character in the architecture. Council and staff discussed higher
maintenance building materials, and noted larger sized buildings create a more institutional look.
Council noted incorporating large windows to view internal pipework of the facility. Council and staff
discussed incorporating an expansion of facility for future needs and balancing needs of city relative to
cost of facility. Project Manager Hammerbeck reviewed the Bellwether proposed test well location, and
noted reports on initial testing of water quality, and flow necessary to towers based on number of
users. Council and staff discussed number of facilities, possible expansions, locations, capacity of
1
facility, noting further discussion at a future Council meeting. Public Works Director Mattson noted
future water supply planning will become routine discussion as infrastructure is
