RE: Major Ditches Contract E12191
Task Order No.2
Dear Mr. Edmonds,
Lockwood,Andrews&Newnam,Inc.(LAN)has completed the work associated with task order number 1 on the
Major Ditches contract E12191(TOO. The recommendations made in the draft report include follow-on work to
realize the vision of the Coastal Bend Hazard Mitigation Plan(HMP)dating back to 2002 and the most recent
capital improvement project following similar scope. Since its inception the Major Ditches project has been about
flood mitigation and due to the modeling LAN has completed it is has been made apparent that much of the goals
for Major Ditches can be met with detailed modeling. Those areas identify as"Damage Centers" in the LAN TO#1
draft report will benefit from the completion of the detailed modeling and the completion of the alternatives
identification and due diligence necessary to determine the costs for these alternatives.
Since our meeting LAN obtained a copy of the Major Ditches Hazard Mitigation Grant Program(HMGP)application
and has reviewed its contents. The current application does not reflect the costs associated with the high level
mitigation alternatives presented nor,in our opinion,does the depth damage assessment. Attached to this letter
is Attachment'A'which is a scope of services for completion of detailed modeling and the completion of depth-
damage assessments using the latest data. Attachment'B'is a consultant fee estimate for completion of the scope
of work presented in Attachment'A'.
Please contact me or Scott Harris our Corpus Christi area Regional Manager if you have any questions or concerns
regarding the information presented.
Respectfully submitted,
Just M.Murra PE,EN

Scope of Services
Task Order#2
IDIQ Major Ditch Improvements (E12191)
I. Description
CONSULTANT entered into an agreement for Task Order No. 1 (TO#1) under the Master Services
Agreement(MSA)for Project E12191"Major Ditch Improvements"with the CITY on September 26, 2017.
The scope of services for TO#1 assumed that the modeling for the La Volla Creek basin would be based on
Federal Emergency Management Agency (FEMA) modeling completed in 2009 by CH2MHill. However,
the models were not readily available from the CITY or Nueces County. Therefore,CONSULTANT prepared
completely new hydraulic models for the study reaches. Additionally,the hydrologic modeling completed
by HDR for the Oso Creek Basin provided by CITY was not conducive for use with the modeled hydraulics
due to the coarseness of the hydrology and the relatively small basins contributing to the studied reaches.
Further,the study scope stated that the study reaches were to be utilized to update reach routing within
the hydrologic modeling using the Modified-Puls method. This could only be accomplished if the basin
delineations allowed for routing of the upstream basins further necessitating the need to complete new
basin delineations, reach routing, and junction identification in a new hydrologic model.
A project status update and report of preliminary results was provided on February 25,2019. Immediately
following the presentation,the CITY requested that CONSULTANT provide a scope of work(SOW)for the
recommendations made regarding the preliminary results. These recommendations included work which
was not included in the SOW for Task Order No. 1. Below is the SOW required for the completion
II. Phase 1—Scope of Work
Task 1. Administrative
1. Meetings with staff—CONSULTANT will prepare presentations and exhibits for
meetings with CITY staff and meeting minutes following each of the meetings for a
total of 5 meetings. Two of the meetings will be used for kick-off and close-out of
the task order,three of the meetings will be used for progress meetings;
2. Field visits—CONSULTANT will complete site visits to determine any changed
conditions which affect the modeling which will be used for the update of the
modeling for La Volla Creek and its tributaries. CONSULTANT will provide a letter to
CITY summarizing the results of the site visit and noting any changed conditions and
providing recommendations as they relate to completing the work;
Deliverables:
• Meeting minutes;
• Meeting presentations of assumptions, results, and recommendations;
■ Electronic copies only
Task 2. Existing Conditions Hydrologic Modeling
1. Updates to Task Order No. 1 Modeling—CONSULTANT will update the hydrologic
modeling,shapefiles,and routing data to accommodate the existing conditions
hydraulic modeling. The rainfall depths used for the 2-, 5-, 10-, 25-, 50-, 100-, and
Exhibit A

Scope of Services
Task Order#2
IDIQ Major Ditch Improvements(E12191)
500-year events will be based on the City of Corpus Christi DRAFT Drainage Design
Manual (DDM);
2. Updates to Task Order No. 1 Modeling(Atlas 14)—CONSULTANT will re-run the
hydrology for the La Volla Creek basin using Atlas 14,Volume 11 rainfall. It is
expected that the CITY will adopt the revised rainfall as its current effective design
rainfall. Therefore,the results of the Atlas 14 model run will be used in the
hydraulic models sent to FEMA. Results will be reported and contrasted with DDM
rainfall for the 2-,5-, 10-,25-, 50-, 100-, and 500-year events;
3. Drainage Area Maps—CONSULTANT will prepare drainage area maps at a 1"=1000'
scale on 22"x34"titleblock showing the subbasin delineation,flow paths,storm
drainage, inlet, hydrologic reaches,junctions,and contour data used for completing
the hydrology;
4. Soils Maps—CONSULTANT will prepare soils maps at a 1"=1000' scale on 22"x34"
titleblock showing the subbasin delineation, and hydrologic soil group data;
5. Land-use Maps—CONSULTANT will prepare land-use maps at a 1"=1000' scale on
22"x34"titleblock showing the subbasin delineation and land-use data used in
performance of the hydrologic calculations;
6. Technical memorandum—CONSULTANT will summarize model assumptions and
results,compile mapping in a technical memorandum in letter format. A draft and
final have been included in the scope of the tasks throughout this task order.
Deliverables:
• Draft technical memorandum (separate report from Technical Memo#1);
• One(1) electronic PDF copy;
• Two(2)full color hard copies;
• Final technical memorandum
• One(1)electronic PDF copy;
• Two(2)full color hard copies;
• Draft HEC-HMS models in electronic format;
Task 3. 1D Riverine Hydraulic Modeling
1. Create New Reaches—CONSULTANT will modify modeling from Task Order No. 1 to
include additional cross sections for seven new reaches shown in Figure 1. The new
reaches have a drainage area of 1 sq. mi.or greater and were not included in the
scope of the previous task order. FEMA mapping and modeling standards define a
floodplain as a flooding source having a drainage area 1 square mile or larger;
2. Create New Hydraulic Model—Create a new 1D stead-state HEC-RAS hydraulic
model for Airport Ditch No. 2, Horne Road Ditch,and Airport Tributary No. 1 Reach
2 with boundary condition from XPSWMM 1D/2D hydraulic model for Horne Road
ditch;

and supporting documentation for the City's application of GLO and HMGP funds;
2. Prepare project descriptions,exhibits,and estimates which will be used by the city's
grant manager when applying for funds. CONSULTANT assumes that city will
provide direction to utilize the preliminary recommendations made during the
February 2019 status update meeting as the basis of forming project scopes and
estimates. CONSULTANT further assumes that due to the limited time available to
respond and finalize the grant applications that the city acknowledges the potential
for significant changes in project scope and estimates during phase 1 of the grant
process.
3. Estimated project benefit will be based on February 2019 modeling and application
of"Depth-Damage Relationships for Structures,Contents, and Vehicles and
Content-to-Structure Value Ratios(CSVR) in Support of the Donaldsonville to the
Gulf, Louisiana, Feasibility Study" by the United States Army Corps of Engineers New
Orleans District dated March 2006. CONSULTANT further assumes that Phase 1 of
the HMGP grant will be used to confirm the depth-damage using the required FEMA
depth-damage calculator;
4. Attend six(6) monthly grant status conference calls and prepare minutes from the
call.
