Subject:
Mary's Creek Detention Enhancement Study
Dear Mr. Kneupper:
Dannenbaum Engineering Corporation (Dannenbaum) is pleased to present this proposal for
engineering services for the above-mentioned project.
In March of 2003, Dannenbaum submitted its final report for the West Mary's Creek Regional
Detention Facility. The report presented the analysis of the hydraulics of a proposed regional
detention facility on West Mary's Creek between FM 1128 and Harkey Road. The report
recommended a comprehensive study to investigate the cumulative effects of all the existing and
proposed regional detention facilities on Mary's Creek. In particular, the report mentioned that the
water surface elevation reductions presented in the final report will have an effect on the operation of
the existing Southwest Environmental Center (SWEC) regional detention facility.
In recent discussions with personnel from the City of Pearland (the City) it was brought to our
attention that the City is in fact concerned about the mutual effects of the proposed West Mary's
facility and the SWEC facility on one another. Moreover, the City indicated an interest in modifying
the designs of both facilities in a way that would yield the best flood reduction benefits possible on
Mary's Creek.
Dannenbaum proposes a hydrologic and hydraulic study of the proposed West Mary's facility and
the SWEC facility that would address the concerns mentioned above. The proposed study would
make use of existing models of the Mary's Creek watershed, which include HEC-1 models of the
Mary's Creek watershed, HEC~2 models of Mary's Creek and ICPR models of the proposed West
Mary's Creek detention facility.
In addition Dannenbaum will incorporate the proposed improvements to the Corrigan Subdivision
(as-is) into the modeling effort described above. Klotz and Associates is currently conducting an
Impact Study for sections of Magnolia drive from roughly SH-288 to Pearland Parkway.
Dannenbaum will coordinate with Klotz and share information as required.
Dannenbaum proposes the following scope of work:
Mr. Doug Kneupper, P.E.

Revised December 22, 2003
PHASE I -Trial HydrOlogy and HydraUlics
The current HEC-1 models do not reflect the simultaneous operation of the proposed West' Mary's
facility and the existing SWEC facility. Therefore, Dannenbaum will need to modify the current
models as follows:
1) Revise drainage sub-area boundaries and the location of HEC-1 nodes to accurately reflect
the location of each detention facility.
2) Add information as necessary to incorporate the proposed Corrigan Subdivision
improvements into HEC-1 (as-is).
3) Revise the Clark Unit Hydrograph parameters in the HEC-1 model to accommodate the
changes to the drainage sub-area boundaries.
4) Develop trial diversion relationships based on the current weir inlet desig-ns for each facility.
5) Perform storage routing computations for the trial hydrologic conditions.
6) Develop HEC-1 hydrographs for the 3-Yr, 10-Yr, 25- Yr, and 100-Yr storm events for input
into the ICPR model.
7) Compute the 3-Yr, 10-Yr, 25-Yr, and 100-Yr profiles in HEC-2 using the HEC-1 flows
developed in the previous step.
8) Develop a trial rating curve for the Mary's Creek cross-section just upstream of the AT&SF
railroad to serve asa downstream boundary condition for the ICPR model.
9) Extend the channel links in the ICPR model downstream to the AT&SF railroad.
10) Input the existing geometric and weir data for the SWEC facility into the ICPR model.
11)Input the appropriate trial boundary conditions and HEC-1 hydrographs into the ICPR
model.
12) Run the 3-Yr, 10-Yr, 25-Yr, and 100-Yr simulations in the ICPR model.
13) Make any adjustments necessary to the ICPR model so that the peak stages and peak flows
computed by ICPR are reasonably comparable to those computed by HEC-1 and HEC-2.
14) Compare the flow diversions computed for each facility in ICPR with the diversion

relationship that was previously input into HEC-1 and make adjustments to the HEC-1 input
as necessary.
15)Re-run the HEC-1 models for the 3-Yr, 10-Yr, 25-Yr, and 100-Yr storm events to
accommodate the changes to the diversion relationships in the previous step.
16) Re-compute the 3-Yr, 10-Yr, 25-Yr, and 100-Yr profiles in HEC-2 using the HEC-1 flows
developed in the previous step.
17) Prepare and submit a brief interim report to the City engineer with appropriate tables, graphs,
and exhibits that summarize the results of the above analysis.
Phase I of the proposed study will end with the completion of the above tasks. At this point the City
will know the mutual effects of the proposed West Mary's facility and the SWEC facility on one
another as they are currently designed. The City will be able to make an informed decision as to
whether the designs should be altered to provide better flood reduction benefits. This will be
addressed in Phase II of the proposed study.
PHASE II - Enhanced Flood Reduction Benefits Analysis
This phase of the study will focus on enhancing the flood reduction benefits on Mary's Creek by
modifying the weir inlet structures of the proposed West Mary's facility and the SWEC facility.
Dannenbaum proposes to work closely with City personnel to determine precise goals for enhanced
flood reduction benefits on Mary's Creek. These goals may include working toward storing two-
thirds of the combined detention volume for the 10-year storm event and at least maintaining or
exceeding the current performance of the SWEC facility. Based on the results from this phase of the
study Dannenbaum will recommend design modifications to the proposed West Mary's facility and
the SWEC facility that would allow the achievement of those goals within reason. The following
tasks are proposed for this phase of the study:
1) Meet with City personnel to establish goals for flood reduction benefits.
2) Determine appropriate modifications for the weir inlet of each facility.
3) Perform steps (9), (11) and (13) of the Phase I analysis to incorporate the modifications.
4) Perform storage-routing computations using HEC-1 and HEC-2.
5) Perform steps (14) and (15) of the Phase I analysis to incorporate modifications.
6) Prepare and submit a brief interim report to the City engineer with appropriate tables, graphs,
and exhibits that summarize the results of the above analysis.

8) Prepare a revised cost estimate for the proposed West Mary's facility if needed.
9) Prepare a final report to the City Engineer.
Phase II of the proposed study will end with the completion of the above tasks.
Our lump sum fee for the proposed scope of work will be $29,740. Our proposed budget is attached.
Time for completion will be approximately 10 weeks from notice to proceed.

Proposal for Engineering Services
Design, Bid, and Construction Phase Services for the
Construction Plans for SWEC Detention Facility Outfall Modifications
Dear Mr. Keller:
Dannenbaum Engineering Corporation (DEC) is pleased to submit this proposal for providing
engineering services for the development of construction drawings for the construction of SWEC
detention facility outfall modifications along Mary's Creek in Pearland Texas. This project
scope includes the preparation of construction drawings based on the results of the optimization
hydraulic analysis to be done by DEC. This work includes the development of construction
drawings for demolition of existing structure and reconstruction of control structures. DEC will
also be available to answer questions, and provide additional information during the Bid and
Construction Phases of the project.
Based on the revised drainage analysis to be done under separate contract, modifications will
likely be designed for the SWEC Detention Pond inlet structure downstream of the Mary's Creek
Detention Pond. This revised budget estimate includes the construction drawings and cost
estimates necessary to bid this project. The bid and construction phases can be handled under
the original budget for West Mary's Creek. Any survey work, if needed, is assumed to be
conducted by others. It is assumed that the SWEC weir modifications will be included in the
construction plans set for West Mary's Creek Regional Detention, therefore, cover sheets and
applicable details will not be duplicated.
The following is a detailed summary of the proposed Scope of Work for the three (3) phases
(Design, Bid, and Construction) of the project. The Pearland Mobility and Drainage Bond
Program (PMDBP) through TC&B will be involved in each milestone of the project as outlined
in the Scope of Work. PMDBP comments will be incorporated before continuing on subsequent
phases.
