HYDROLOGIC AND HYDRAULIC STUDY
Prepare a comprehensive drainage study of the projects. The drainage study report will be conducted
in two parts:
A. Existing Conditions Analysis
Schedule and attend meetings on a regular basis with City of Pearland/Program
Manager for drainage coordination.
Identify existing drainage outfalls along the projects. A site reconnaissance will be
performed to vehfy drainage outfalls, drainage patterns, and existing cross drainage
structures. Supplemental topographic survey may be required to obtain pertinent
physical features along the drainage outfalls.
Obtain available hydrologic and hydraulic data and computer models 0tEC-1 and
HEC-2) from applicable drainage authorities, to the extent possible, for use in
analysis and determination of existing 5-, 25- and 100-year water surface elevation of
bayous, creeks and ditches along the projects.
Prepare a watershed map and identify existing drainage boundaries. Draihage
boundaries will be obtained using available contour maps and through limited field
reconnaissance.
Compute peak flows for the existing drainage and proposed systems in accordance
with Brazoria County Drainage District//4 and City of Pearland criteria and
methodology.
Determine the hydraulic capacity of the existing drainage structures and outfalls
along the project route. The 5-, 25- and 100-year water surface elevations will be
computed at the drainage outfalls.
Determine the profile of the natural ground along each proposed right-of-way, and
the existing roadway profile. This data will be utilized in the development of design
roadway profiles.
Superimpose these profiles on a drawing along with the 5-, 25- and 100-year water
surface elevations. The profile drawing will provide an overall view of the
roadway/existing ground elevations with respect to the various storm design
frequencies for the length of the project. This will enable Project Engineers to
determine the most feasible proposed roadway profile.
Summarize the above items in an interim progress submittal. Drainage areas and
sheet flow will be presented graphically in an exhibit. The plans and profiles will
also be included. Two copies will be submitted for review.
A-2-1
10.
Coordinate with all applicable govemmert agencies including Brazoria County
Drainage District #4 and City of Pearland.
Preliminary Impact Analysis
Determine a hydraulic gradeline starting at the outfall channels for each storm sewer
system in order to obtain a design tailwater for each existing system. The design
tailwater will be the starting basis for the design of the proposed storm sewer system.
Limit the outfalls for drainage areas into existing storm sewer to existing capacity
flows, which will be determined. Alternate flow routes, if feasible, will be looked
into for relieving storm sewer overload. The amount of the total detention storage to
control storm sewer runoff for the design frequency will be determined.
Determine drainage areas and flows for cross drainage systems as part of the
preliminary impact analysis. Sizing of the drainage crossings and hydrologic
information, once determined, will be provided to the Project Engineers.
CalcUlate the cut and fill impact quantities. Determine any impact on the right-of-
way requirements due to the above analysis.
Prepare a preliminary impact analysis, which shall include the preliminary findings of
the proposed cross drainage structures, bridge layouts, storm sewer capacities,
requirement for.line rerouting, preliminary detention storage volume and initial
recommendations on how to mitigate the storm impact on the receiving streams. The
storm sewer, conceptual and generic discussions of alternatives considered, a
comparative cost associated with each alternative, and recommended solution.
Provide eight (8) copies of the drainage study report to Brazoria County Drainage
District #4 and of City of Pearland for review and comment. Recommendations at
this point should be generic and conceptual in nature, mainly for discussions with
Brazoria County Drainage District #4 and of City of Pearland.
Final Impact Analysis
The final impact analysis will be performed on bayous, creeks, and ditches as related to the
City of Pearland and FEMA criteria 5-, 25- and 100-year storm. The impact prediction is
presented as follows:
Finalized drainage areas for the existing and proposed conditions along the project
route.
2. Finalize the hydraulic conveyance capacities of the existing drainage outfalls.
Obtain current hydrologic and hydraulic computer models from government agencies
and review and comment on the models. Current models will be updated to existing
conditionS and submitted to Brazoria County Drainage District #4 and of City of
Peafland as the revised existing condition model.
A-2-2
7.
Analyze existing and proposed drainage system and quantify the increase in 100-year
peak flows resulting from the roadway improvements. Compute existing and
proposed peak flows by using hydraulics and hydrologic methodology and computer
models. The additional lines should be accounted for the increasing percent
development.
Analyze proposed roadway and outfall drainage improvements to quantify impacts to
revised existing conditions model.
Base storage computations on hydrograph calculations and peak flows obtained in
Item B above. A mitigation volume for the 100-year storm will be computed.
Compute right-of-way corridor 100-year floodplain volumes for existing and
proposed roadway elevations. No decrease in 100-year floodplain volumes will be
allowed without adequate off-site mitigation. Hand calculations shall be provided
which quantify the cut and fill within the 100-year floodplain, if any occur. Identify
the additional right-of-way to satisfy floodplain and/or detention requirements.
Prepare conceptual 100-year sheet flow analysis for the project utilizing existing and
proposed conditions. Determine impacts of the proposed vertical alignment on sheet
flow.
Provide eight copies of a separate drainage report (signed and sealed by a Licensed
Professional Engineer) to City of Pearland and Brazoria County Drainage.District #4.
