STUDY OF GROUNDWATER CONDITIONS AT THE
LANGONI SOCCER FIELDS LOCATED AT 24 STREET

DEPARTMENT: PUBLIC WORKS
ISSUE
AGENDA ITEM #
DATE : February 28, 2000
Should City Council authorize a hydrogeologic study of groundwater condition at the Langoni Soccer
Fields located at 24 Street & High Street.
RECOMMENDATION
Approval of this Resolution
BACKGROUND
Several residents along Cheyenne Blvd. have complained to the administration about groundwater
seepage into their basements. They believe the seepage is due to irrigation of the soccer field complex
that lies to the east of their properties, and also, uphill from their properties.
The proposed hydrogeologic study by Kleinfelder will provide the City with information on groundwater
conditions in the area and possible solutions for groundwater control.
FINANCIAL IMPACT
The cost of the study is $7,420.00 and will be taken from unobligated Community Development Block
Grant Funds, Account No. 250 - 9540 - 600.80 -50 CD0047.
This study will take approximately 12 months.

Subject: Proposal for Hydrogeologic Study
24 ' Street Soccer Complex
Pueblo, Colorado
Dear Mr. Cvar:
�9 ! ;
Kleinfelder is pleased to present this proposal to evaluate seepage conditions at the athletic fields
northeast of the intersection of Cheyenne Avenue and 24"' Street in northwestern Pueblo,
Colorado. We understand that several residents of Cheyenne Avenue, located west of the athletic
fields, have complained about groundwater seepage in their basements. Furthermore, those
residents have claimed that the groundwater problem is directly associated with the drainage and
watering of the athletic complex located to the east. You requested that Kleinfelder submit a
proposal for a hydrogeologic and geotechnical evaluation of the situation. It is our understanding
you specifically want us to express professional opinions as to:
• The extent and severity of the claimed groundwater problem;
• If, and to what extent the drainage and watering of the athletic fields causes or contributes
to the claimed groundwater problem;
• The feasibility and order -of- magnitude cost impacts of potential groundwater control
measures; and
• The extent to which groundwater control appears to be a public or a private obligation.
This situation should be approached as a phased investigation. We believe that an initial
evaluation, based on site observations and available information, will support a meaningful
preliminary assessment. Based on the results of that preliminary assessment we will perform a
more - extensive investigation, involving test borings and groundwater flow analysis. Kleinfelder
therefore proposes to perform the following tasks:

• We will review the available data from City files concerning the design, construction,
maintenance, drainage, and watering schedule of the athletic complex. We will also
review data from the files of our predecessor firm, Lincoln DeVore, regarding soil and
groundwater conditions in the area.
• We will make a surface reconnaissance of the athletic fields and adjacent properties to the
west in the area between 24 Street and 27 Street. This reconnaissance will document
evidence of seepage or other groundwater problems immediately west of the athletic
fields.
• We will advance a total of 12 boreholes to bedrock in the area surrounding the athletic
fields at locations determined by our field reconnaissance. The boreholes will be logged
and sampled, with a temporary piezometer placed in each borehole for groundwater
monitoring.
• We will survey the top of borehole elevations and the approximate ground elevations
adjacent to the affected residences. This survey may include interviews with selected
homeowners or tenants.
• We propose monitoring the piezometers for a minimum of one year. During this time
frame the depth to groundwater will be measured once a month to help estimate seasonal
groundwater patterns.
• We will analyze our findings to develop a conceptual model of groundwater conditions,
to develop alternative measures for groundwater control, and to judge the likely
effectiveness of those measures. We will also provide rough estimates of costs for those
measures.
• We will prepare and submit a letter report documenting our findings and opinions.
Our work will require that the City compile the available records in City files regarding the
athletic complex. and make those records freely available to us. We also request that the City
provide us with a topographic map of the study area, if available. Kleinfelder will submit 5
copies of the report to you.
For the scope of services outlined above, we estimate that our fees will be $5,800.00. Changes to
the scope of services may result in extra fees being charged. An additional $135.00 will be
charged per month for a one -year period for well monitoring and data analysis. If work
exceeding that outlined in the scope of services appears necessary, we will contact you for
explanation and authorization prior to incurring such extra fees.
