−Some areas have road side drainage ditches

•Planning for future growth is being doneproperly

−Water storage needed for new water sources

−Renewable surface supplies

General Observations (con’t)

•Water and sewer lines in older parts ofthe City are starting to need replacement

•Messages from City about waterconservation are not well read

−Need to find more effective messagingapproach

•Make sure security at 144th Ave. watertreatment plant is adequate

Current Water Supply Sources

•The Northern Colorado WaterConservation District

•Denver Water Department

•Reclaimed (treated) wastewater

•Raw water from water rights owned byBroomfield

Capacity of Potable Water System

•Build out need (37,300 tap equivalents)

•Present water supply (28,171 tap equivalents)

−8,994 acre-feet from Northern Colorado WaterConservation District

−6,500 acre-feet from Denver Water

•Future water supply (11,000 tap equivalents)

−Windy Gap

•Allow for possible future higher densityrebuilding after buildout

Capacity of Non-Potable Water Systems

•Non-potable reuse water

−3,100 acre-feet to irrigate 1,275 acres

•Big Dry Creek Wastewater Treatment Plant

−12 million gallons per day present capacity

−11.8 mgd needed at buildout

−Will require three to five lift stations from eastand north

•Storm water drainage and flood control

−Broomfield is mainly within the Urban Drainageand Flood Control District (UDFCD)

•Except for lands annexed from Weld County

Water Resources for Future Growth

•Windy Gap Water

−Diverted from Colorado River Near Granby

−Junior Water Right

•Available only at high stream flow

•Water is taken when available and stored forlater use

−Requires Storage to “Firm” the Supply

•Grandby Reservoir (when storage capacity isavailable)

•Broomfield Reservoir (5,000 acre ft.)

−Budget cost $75 million

•Chimney Hollow Reservoir (Broomfield share25,000 acre ft.)

−Broomfield share of budget cost $106 million

•Adequately Plan and Coordinate UtilityDevelopment to Buildout

−City Water and Sewer Utility DepartmentPlan for 15 to 30 years into the future

•System repair, maintenance and replacementafter buildout

•Finance Utilities for Buildout

•Sustainable Utilities

−Rely on renewable surface water resources

−Maximize water reuse

Planning Goals (con’t)

•Community Aesthetics

−Build necessary “unattractive” facilitiesbefore nearby neighborhoods develop

•Public Health

−Reduce residents on wells and septicsystems

•State of the Art CommunicationsInfrastructure

−Encourage high speed fiber optic systemthroughout the City

New Recommendations in 2016 Plan

•Convene Annual Utility Planning Meetings

−Linear utilities (water, sewer, Xcel, CenturyLink, etc.)

−Cell phone towers
