Public Works
Included in the 2017 CIP its the design and construction of Well #21. This well will be located
in the southeast quadrant of the Hiighview Av./Dod Blvd. intersection.
Design off Well 21 began in the fall of 2016 with construction expected in 2017. The
estimated design and construction costs for Weill .t,21 included in the 2017 CUP is $ 75,000.
After significant analysis, staff has concluded that an additional well (Well H22) could also be
constructed on this site. Well ti22 was included in the 2017-2021 CLP in 2019 at a cost of
$918,750. The treason this its possible is that the wells will be constructed in diffffeirent as uiffers,
separated by different confining layers of earth that will eliminate the negative impacts of the
wells being located so close to one another.
This is a significant opportunity as it will result in an estimated cost savings of up to $230,000.
These cost savings can be irealiizedl° by being able to construct the wells as part off a single
contract and being able to utilize the infrastructure and site improvements for two wells
instead off just one. It will also allow the City to delay the construction off Well 23 a inirnum
of .ne year until at least 2020 and possibly allow delaying the construction of additional wells
planned in 2021
Adequate funding for this project is available in the Water Trunk (Fund, Allso, as part off this
project the City its required to install two olbseirvation wells and plans to seal and aban.ion
Well #7 that hasn't been used in over 10 years due to interference with private wells.
Staff recommends that the City Council authorize advancing the construction of Well W22 to
2017 to be constructed as part of the current Well N 21 contract.
