completion of the studies and coordination with the City. Additionally, Halff will coordinate internal
independent quality control and assurance reviews of all deliverables prior to submitting to the City. These
reviews will be documented in QAQC checklists with comment resolution.
MDP Rollout and Training
Support for GIS Services
To support the hosting and distribution of the Master Drainage Plan studies and spatial data, Halff will
provide support services to the City's GIS Services. This will include internal capabilities for hosting the
data from initial setup to an initiation of a web map interface. Ongoing updates will be supported as new
studies are completed and made available.
13620 Briarwick Drive, Suite 100, Austin, TX 78729 � halff.com
::: halff
Additionally, Halff will coordinate with and provide support services to the City's GIS Services to evaluate
options for making the data externally facing and available. This will include coordination of data access
needs (Viewable versus Downloadable) and capabilities of current license level.
Internal City Staff Training
To support the distribution, understanding and application of the previously completed Master Drainage
Plan studies and spatial data, Halff will provide training via lunch and learns for internal City department
staff to include Development Services, Parks and Recreation, Planning, Transportation Planning, Public
Works and GIS Services. Training materials will be developed and catered to the needs of the respective
departments. Halff will provide up to three (3) one-hour in person lunch and learn sessions.
Support of External Rollout
To support the City's distribution of the previously completed Master Drainage Plan studies, Halff will
conduct a stakeholder survey of local consultants on their needs, use and application of the data. This
feedback will facilitate further discussion and direction for the City to develop a short term and long-term
data rollout plan.
Capital lmprovement Planning
Consolidate, Review and Assess Existing Projects
Halff will consolidate and review projects lists known to Halff and provided by the City of all stormwater-
related projects. This shall include but not be limited to the following project lists: Stormwater
Management Program, CCTV, Plumber Park Retrofits, CIP, and Regional Flood Planning.
The City shall provide any additional City projects underway by other departments that may be reviewed
holistically with the stormwater— specific projects for review of potential integrated solutions.
2D Flood Assessment
Halff shatl develop a 2D rapid assessment model for the City and ETJ to identify flooding hots and ponding
locations within the playa system. The 2D rapid assessment will be developed in HEC-RAS, Version 6.4.1
for 24-hour duration, 2-, 10-, 25-, and 100-year ACEs. The following assumption will be made:
1) Existing conditions land use assumptions from inspection of aerial photography and impervious
area delineations provided by the City.
2) Infiltration parameters will be defined using curve number loss methodology.
3) Best available LiDAR topographic information provided by the City will be used to create a ground
surface mesh. Initial conditions for playas will be based on the elevations represented by the LiDAR.
4) Additional breaklines will be included in the model to establish greater definition of overland flow
patterns, as appropriate. Storm drain conveyance system will not be included in the rapid
assessment model.
5) Manning's n values for hydraulic roughness will be based on existing GIS land use datasets.
6) Rainfall will be defined using NOAA Atlas 14, in alignment with the City's Drainage Criteria Manual.
7) Delineate areas of flooding hot spots and ponding locations during each storm event.
13620 Briarwick Drive, Suite 100, Austin, TX 78729 � halff.com
::: halff
8) Validate results to available flood risk mapping, including the previously completed rapid
assessment, Fathom cursory floodplains, and base level engineering.
Hot Spot Analysis
Halff will review results of the 2D rapid assessment to identify areas of significant ponding and flow
conveyance. These areas will be reviewed against 911 Database of flood complaints provided by the City
and other known flood issues as provided by City Staff. These areas will be overlaid with the consolidated
projects to correlate identified flood risk areas with already identified project areas. The resulting analysis
will provide an updated lists of drainage issues throughout the City that will be prioritized for CIP planning.
A maximum of 30 hot spot areas will be reviewed.
Project Prioritization Criteria and City Collaboration
Halff will meet with the City to establish criteria for CIP project prioritization. This will include but not be
limited to:
1. Public Safety
2. Public Opinion
3. Correlation to Other City Projects
4. Cost and Available Funding
Halff will provide up to two (2) workshop sessions with key City staff to review and prioritize projects. A
final CIP project list will be developed with priority and conceptual level project costs. Halff will identify
these projects into categories for Maintenance, and Small, Medium and Large Construction projects.
Halff will work with key City staff to identify alignment with ongoing and future City projects and review
potential funding opportunities. This may include stormwater utility fees, public-private-partnership, and
state funding as well as other funding sources identified and discussed with City staff.
Report Documentation
Halff will prepare a Stormwater CIP Summary Report that includes identified problem area descriptions,
preliminary evaluation methodology and results, CIP ranking procedures and results, problem areas
selected for detailed study, proposed CIP alternatives, exhibits and opinions of probable construction cost
based on current regional unit costs. Halff will, in coordination with City staff, identify priority of future
feasibility studies and MDP playas studies informed by the results of the rapid assessment, hot spot
analysis, prioritization and funding review.
Master Drainage Plan Playa Studies
System E Update
Halff will perform a hydrologic and hydraulic modeling on Subbasin E122A which is considered as the
study area for the System E Update. The study will be performed using ICPR software, which is capable of
1D and 2D modeling analysis. The playa basins will be modeled based on assumed future fully developed
conditions determined by the City planned land use and typical development patterns. The objectives of
modeling will be to redefine the overland flow from anticipated overflows from Clapp Park traveling east
of Interstate 27. Modeling will incorporate overland and subsurface conveyance to identify the overflow
inundation traveling southeast to Yellow House Canyon.
13620 Briarwick Drive, Sufte 100, Austin, TX 78729 � halff.com
::: halff
The City will provide Halff with any approved Drainage Analysis Reports and hydrologic and/or hydraulic
analysis computer models within the study area. The City will provide Halff with record drawings and other
existing information relating to storm drain locations and depths within the study area.
Hydrolo�y and Hydraulics Analvsis
The fully developed conditions analysis will analyze the hydrologic and hydraulic conditions for Subbasin
E122A to evaluate the overflow path and discharge from Subbasin E122A. Halff will leverage the Clapp
Park Study provided by the City to establish an upstream inflow hydrograph. The upstream model and
additional supporting data will be reviewed and evaluated by Halff. Coordination with the City will occur
prior to any updates to the Clapp Park Study. Any updates made to the Clapp Park model, if deemed
necessary, will be an additional service. Halff will evaluate overland flow and subsurface storm water
conveyance. Storm drain system within the study area will be modeled with the most up-to-date data.
Overland flow will be modeled using the best available LiDAR topographic information provided by the
City most recent with representative cross sections of the overflow inundation. Based on the Study results,
Halff will update the overflow discharge from E122A to the downstream playa (L005) and evaluate the
impact to the downstream system. Halff will leverage previous models developed as part of the City MDP
studies to evaluate the change to the downstream playa system in System E.
Floodplain Mappin�
Mapping shall follow standard mapping procedures utilized in the City's MDP study updates. Overflow
inundation results will be mapped on best available LiDAR data showing the 100-year and 500-year FFP
floodplain extents. Halff will evaluate the impact to the downstream playa (L005) and downstream
conveyance system mapping and revise mapping to account for the revised inflows.
LOMR
Halff will prepare the LOMR application documentation and coordinate with City staff for approval and
signature prior to submittal. Halff will coordinate and participate in two (2) iterations with FEMA during
the review process. The City will be responsible for the required FEMA review fee upon submittal to FEMA.
System F — L196
Development interest is occurring east of Interstate 27 and south of 82"d Street, potentially impacting
playa lakes No. 81, 196, and 195A. Playa lake No. 81 has previously been studied through the completed
Master Drainage Plan, however, playa lakes No. 196 and 195A have not been studied. These two lakes
are independent of each other and may be studied separately. This scope of work is specifically for the
analysis of playa lake No. 196.
To establish flood extents and thoroughfare capacity analysis for playa lake No. 196, Halff will conduct
hydrologic and hydraulic modeling using ICPR software. The playa basins will be modeled based on future
fully developed conditions based on City planned land use and typical development patterns. The
objectives of modeling will be to identify expected stormwater runoff volumes, impacts of runoff to the
major thoroughfare crossings and thoroughfare capacity analysis. Halff will compile the datasets used to
develop the MDP models into a standardized GIS database for integration into the existing GIS database
and use by City staff. Additionally, the results of the hydraulic modeling will be used to develop inundation
areas and expected flow paths of the stormwater runoff. Halff will prepare a summary MDP report for
each playa basin documenting the assumptions, model parameters, and results. No LOMR is included as
part of this scope of work.

4th and Wood — Near Leprino Site
Playa lakes No. 72, 73, 74, and 321 have been previously studio by Hugo Reed and Associates in support
of the development of the Leprino Site. This existing study completed future fully developed analysis
based on future land use assumptions but did not complete thoroughfare capacity analysis. Halff will
leverage the existing study and update hydrology for playa lakes No. 72, 73, 74, and 321 for future fully
developed impervious cover based on site plans and analyze the thoroughfare capacity for 4"' Street and
Wood Avenue. Halff will prepare a summary MDP report for each playa basin documenting the
assumptions, model parameters, and results and the MDP spatial data for incorporation into the final
MDP geodatabase. No LOMR is included as part of this scope of work.
Feasibility Studies of Existing Flood Risk Areas
Dunbar Lake
Dunbar Lake is currently experiencing undercutting of the sidewalk on the east side of Canyon Lakes Drive.
To assess the condition and feasible solution, Halff will acquire and review any available modeling data,
as-built plans, and survey from the City which may be used to establish current flow conditions.
Additionally, Halff will leverage the results of the Rapid Assessment completed as part of this scope of
work, to validate existing model results. Field measurements and photos will be obtained to assess the
undercutting extents. Halff will determine the amount and extent of overflow and develop one (1)
conceptual level alternative to repair the undercutting.
If seepage is identified during field visits, City staff shall be notified before proceeding further with the
study. No survey or geotechnical analysis is included as part of this scope of work and will be Additional
Services.
Deliverables will include a technical memo and exhibit documenting the proposed improvements. No
design plans are included as part of this scope of work.
