REQUEST: Utility Department Requesting Authorization to Execute Amendment 51 for
Consulting Engineering Services with Conklin, Porter & Holmes Engineers, Inc.
PURPOSE: The purpose of this Board item is to request authorization for the execution of
Amendment 51 for a Mt. Greenwood Percolation Pond Investigation with Conklin,
Porter & Holmes Engineers, Inc. at a cost of$9,475.00.
CONSIDERATIONS:
This study is needed to address the concerns of residents of Cello Circle about the
impact of the Mt.Greenwood Percolation Ponds on drainage problems in the area. During
wet weather periods or the rainy season, the residents experience problems with standing
water. This is an ongoing problem that has improved since the Utility staff reduced the
utilization of these ponds during rainy season. However, these ponds are a necessary and
permitted part of the effluent disposal system for the West Water Reclamation Facility.
As part of the study, CPH Engineers, Inc. will utilize the services of a hydrogeologist
subconsultant, L.J. Nodarse & Associates. The scope of work includes gathering field data
to establish a model to evaluate the impact of the ponds on the surrounding area. A more
detailed description is included in the hydro geologists proposal to CPH which is attached.
The cost for the study is $9,475 of which $8,675 is for the subconsultant.

Attn: Mr. Terry Zaudtke, P.E.
RE: Proposal for Evaluation of Mount Greenwood
Effluent Disposal Ponds and High Water Ta~le Conditions
Winter Springs, Seminole County, Florida
Dear Mr. Zaudtke:
In accordance with your request, L.J. Nodarse & Associates, Inc. (UN) is pleased to present for
your review and consideration, our proposal to characterize the effective aquifer system at the
subject site and model the effluent ponds to assess the on-site and off-site impact on current
groundwater conditions. Based upon our understanding of the City of Winter Springs' requirements
and needs, the following is a brief description of our proposed scope of services:
Task 1 Drill a series of soil borings and obtain site specific hydrogeologic characteristics of
soils and surrounding areas. This will include collecting undisturbed tube samples,
conducting field permeability tests and measuring the current stabilized groundwater
levels on-site. Laboratory tests will include soils classifications and permeabilities
on the undisturbed Shelby tubes removed on-site. The information gathered in
Task 1 will be utilized in model calibration during Task 2 activities.
Task 2 Utilizing existing and previous available data generated on-site, an effort will be
made model existing conditions on-site to determine the impact loading of effluent
has on groundwater conditions and surrounding areas. This effort will include the
characterization of the aquifer system, identification of confining soil layers, setting
up a three-dimensional groundwater flow model, calibration of the model to existing
observed conditions, and modeling the site with and without the influence of the
percolation ponds. -

Task 3 A final report will be prepared outlining all field and modeling activities including
an assessment the percolation ponds have on groundwater conditions at various
potential loading rates. The report and all information will be prepared in such a
manner to support any potential legal action considered as part of activities on
surrounding properties.
It is estimated we can complete the above generally outlined scope of services for a not to exceed
cost of $8,675.00. Attachment A is a breakdown of the costs projected for this project. It is further
estimated that we can complete all field and modeling activities within two (2) weeks of notice to
proceed, with the engineering analysis, modeling and preparation of the report with
recommendations completed two (2) weeks upon completion of all field and laboratory work.
CLOSURE
UN appreciates the opportunity to submit this proposal and we look forward to working with you
and the City of Winter Springs on this project. If you have any questions or if we can provide any
additional information, please feel free to call us at your convenience.
Sincerely,
L.J. NODARSE & ASSOCIATES, INC.
