ATTACHMENT "A"
SCOPE OF SERVICES
Mobile LiDAR Project
Floodplain Project: FP-11-017-PF
Michael Baker Jr., Inc. (Baker) is pleased to present this scope of services to the City of Fort Worth for a Mobile
Light Detection and Ranging (LiDAR) project to prepare data and products in the areas of concern thereby
providing City staff with better tools to assist them in flood mitigation and other related initiatives. There are three
(3) study areas (Sunset Acres, Hulen Bend and Lake Worth) as shown in Figure 1.
The primary objective within the three study areas is to provide more accurate ground elevations, finished floor
elevations and adjacent ground elevations for the structures. This information coupled with the Base Flood
Elevations (BFEs) from the recently issued FEMA Flood Insurance Rate Maps (FIRMS) will allow the City to
accurately assess the impact of these newly adopted floodplain maps on the individual property owners.
Specifically, it will determine which structures are subject to future Letter of Map Amendment (LOMA) processing,
and which structures warrant more detailed investigation.
Mobile LiDAR technology was chosen because it has been proven to offer time and cost advantages. It provides
accurate efficient, cost effective survey -grade data with no public inconvenience. Mobile LiDAR data can fill in
gaps from traditional aerial LiDAR, provide additional accuracy in target areas, and supplement previously collected
data. It generally does not require accessing private property, and represents a hybrid approach of the traditional
methods (aerial LiDAR and field survey) typically used for data collection.
The Sunset Acres study area represents several hundred homes that were not previously in the Special Flood Hazard
Area (SFHA), but, with the new floodplain maps are now in the SFHA. This change has a significant impact on
these residents. Mobile LiDAR data will be used to remap the FEMA floodplains and correct the inaccuracies in
existing mapping and allow those residents that should not be mapped in a SFHA to be removed
Additionally, for the Hulen Bend study area, the data to be collected is also needed in order to prepare a detailed
drainage study. This area has a history of significant flooding Accurate topographic data is needed to develop a
thorough analysis of this area. Mobile LiDAR data will be used by the City of Fort Worth to supplement existing
low -resolution data to create a more detailed topographic basis for the more robust modeling analysis planned to
address the complex flooding problems that have been experienced in Hulen Bend.
The Lake Worth study area has several unique challenges. The terrain and tree cover has made it difficult to obtain
accurate topographic data using traditional aerial LiDAR. Mobile LiDAR can overcome these difficulties, thereby,
providing the Fort Worth Water Department with information needed for assessments of the dam, volumetric
determinations of Lake Worth and assistance with proposed improvements, including the perimeter trail.

1.1 - Control Survey
18 control points as shown in Figure 2 will be established using the control survey specifications.
1 2 — LiDAR Collection
Baker will utilize their Mobile LiDAR system to collect information along each street identified in Figure
2. The Baker collection staff will make practical efforts to effectively inundate the project area with high
density Mobile LiDAR data. Gaps due to laser shadowing from obstructions will be minimized using
multiple passes and approaches.
1.3 — LiDAR and Photo Processing
The LiDAR data will be constrained to the established control points improving the spatial accuracy of the
3D model (point cloud) of the study area to, approximately, 1 inch vertically. The ground points will then
be extracted from the point cloud to create the "bare earth" points used for earthworks and hydraulic
modeling A thinning program will be run to reduce the number of points to about a point every foot.
These pomts will be triangulated to create the 1 foot digital elevation model compatible with the ESRI
software as a deliverable. The thinning process will be run a second time again on the bare earth points and
reduced to a point density of 5 feet between points This will also be delivered in ESRI compatible fouuat
The 1 foot and the 5 foot points will also be delivered in the form of an X Y & Z file to support almost any
terrain modeling application. The full featured point cloud will be colorized to create a LAS 1.2 (Log
ASCII Standard) file The Tarrant County Appraisal District parcel boundary shape file will be used to
`tile' the point cloud based on parcel boundary extents. The parcel point clouds will be used in the
followmg steps:
Photo Processing
The photo locations from the field collection will be "geo-referenced" with a hyperlink to the photo linage
and delivered in an ESRI point shape file The hyperlink will use a "relative path" to support consistent
connectivity from the point to the image. The images will be delivered in JPEG format.
1.4 — Elevation Canture
The parcel point clouds will be used to populate an ESRI shape file that contains the following fields:
A) Parcel ID
B) First Floor Elevation (within, approximately, 1 to 3 inches for screening purposes)
C) Adjacent Grade Elevation (within, approximately 1 to 3 inches for screening purposes)
D) Base Flood Elevation (from latest available DFIRM (Digital Flood Insurance Rate Map) for Tarrant
County)
1.5 — Raw Floodnlain Manning
Floodplam mapping for the project area will be generated using the 1 foot spacing DEM (Digital Elevation
Model) data created for this project and water surface elevations published in the FEMA flood profiles. No
smoothing process will be applied.
1.6 — FEMA Floodnlain Manning
Floodplain mapping generated in Task 1.5 will be smoothed to meet FEMA specifications.
1.7 — HAZUS Enabled Database
A HAZUS enabled database will be provided that is populated from information readily available from
three sources: (1) the terrain data collected as a part of the Mobile LiDAR data collection effort, (2) data
included for each parcel within the Tarrant County tax records, and (3) the most recent DFIRM for Tarrant
County.
The ground elevations obtained with the Mobile LiDAR unit will be combined with the DFIRM data cross
sections, base flood elevations and floodplain boundaries to create accurate flood depth grids.
Michael Baker Jr., Inc. Page 11 of 18
Contract for Mobile LiDAR Project
The Mobile LiDAR unit will collect first floor elevations for structures, which are a crucial element for the
HAZUS flood analysis. Other attributes like replacement costs, building type or year built will be derived
from the assessor's database and converted into HAZUS accepted formats.

feet in North American Vertical Datum of 1988 (NAVD 88) An ASCII text file containing the X, Y & Z
points for the 5 foot grid spacing will also be provided for use in other applications.
The point clouds that are collected will be colorized based on the photography and then tiled out into
smaller files based on the Tarrant County Appraisal District parcel boundaries shape file This will
provide a more manageable data set so that the computer requirements for using the data are lessened.
Using the bare -earth DEM, contours will be derived at 1 foot intervals. The resultant contours will be
delivered in ESRI Shape file format. Due to the nature of the Hulen Bend site having closed drainage
systems, the extra step of delineating breaklines will be performed The process of establishing breaklines
allows for controlling the topographic surface behavior caused by curb and gutter systems. The resultant
breaklines will be delivered in ESRI Shape file polyline format.
4.4 — Elevation Capture
The LiDAR data will be used to identify the first floor elevations as well as the adjacent ground elevations
for all structures in the 3 study areas. The data will be delivered in an ESRI shape file that contains the
fields for the parcel ID, First Floor Elevation (FFE), Adjacent Grade Elevation (AGE), Base Flood
Elevation (BFE), if available, and the date entered This will be used by the City staff in determining the
need for LOMAs. See Figure 5 for an example.
4.5 — Raw Floodplain Mapping and FEMA Floodplain Mapping
Raw floodplain mapping and FEMA floodplain mapping generated for Sunset Acres will be provided in
ESRI shape file formatted to comply with FEMA DFIRM.
4.6 — Detailed Lake Worth Features
4.6.1 - Boat Dock Planimetrics and Boat Dock Elevations
Using a combination of Mobile LiDAR and Static Scanning a detailed topographic map of the
public boat ramps surrounding Lake Worth will be developed. Planimetric features such as
parking, docks, signs and utilities will be combined with elevation data to clearly depict the fixed
improvements. The resulting topographic map will be delivered in Micro Station DON (or
AutoCAD DWG) and ESRI Shape file format.
4 6 2 - Detailed Dam Survey
Similar to the boat ramps, static scanning will be deployed in addition to the Mobile LiDAR A
closed traverse will be performed around the dam at the east end of Lake Worth including the
flow area from the spillway providing more dense coverage. Planimetric features of fixed
improvements and vegetation will be mapped in Micro Station DGN (or AutoCAD DWG) and
ESRI Shape file format
4.6.3 - 594-foot and 600 Foot Contour
594-foot and 600-foot contours will be provided, in separate GIS shape files, to accurately represent key
jurisdictional and FEMA floodplain boundaries around the lake.

HEARING:
SUBJECT: Authorize Execution of a Professional Services Agreement with Michael Baker Jr., Inc., in
the Amount of $427,798.00 for the Mobile LIDAR Project, Increasing Appropriations in the
Stormwater Utility Fund and Decreasing the Available Cash Balance in the Amount of
$328,091.00, Authorize Transfer of Funds from the Lake Worth Gas Lease Capital
Improvement Fund to the Stormwater Utility Fund, Increasing the Estimated Receipts and
Appropriations in the Stormwater Utility Fund in the Amount of $99,707.00 and Adopt
Appropriation Ordinances (COUNCIL DISTRICTS 3, 6 and 7)
RECOMMENDATION:
It is recommended that the City Council:
1. Authorize transfer of funds from the Lake Worth Gas Lease Capital Improvements Fund to the
Stormwater Utility Fund in the amount of $99,707.00;
2. Adopt the attached appropriation ordinance increasing the estimated receipts and appropriations
in the Stormwater Utility Fund in the amount of $99,707.00 from available funds;
3. Adopt the attached supplemental appropriation ordinance increasing appropriations in the
Stormwater Utility Fund in the amount of $328,091.00 decreasing the available cash balance by the
same amount; and
4. Authorize the execution of a professional services Agreement in the amount of $427,798.00 with
Michael Baker Jr., Inc., for the Mobile LIDAR Project.
DISCUSSION:
The professional services Agreement recommended by this Mayor and Council Communication is for
the Mobile LIDAR (Light Detection and Ranging) project; a survey data collection and floodplain
mapping project that will correct FEMA floodplain mapping errors, resulting in a direct economic
benefit to negatively affected property owners. The project will also quantify the number and types of
dock and pier structures in Lake Worth, enhance emergency response operations, and develop
detailed topographic information to assist in trail and park enhancements around Lake Worth.
On September 25, 2009, FEMA updated all of the floodplain maps for the City of Fort Worth. The City
is required to use these maps so that affordable flood insurance will continue to be available to our
residents, and the premiums will be reflective of the actual risk. Unfortunately, the 2009 floodplain
maps included many significant errors, incorrectly placing as many as 500 homes and businesses in
the floodplain. The City of Fort Worth is required by federal regulations adopted by our Floodplain
Provisions Ordinance to request re -mapping of incorrect FEMA floodplain boundaries when the
boundaries are known to be inaccurate.
The average cost to a resident of Fort Worth for a flood insurance policy in a floodplain is
approximately $950.00 per year. Force -placed flood insurance policies through mortgage companies
are frequently two -three times more expensive. The errors in this particular situation could impose as

much as $1.4 million in unwarranted flood insurance premiums on Fort Worth property owners.
Mobile LiDAR technology will be utilized to quickly and accurately survey each of the project areas to
determine to what extent the floodplain must be re -mapped. Contour data generated by the Mobile
LiDAR survey will be used to determine accurate boundaries of the FEMA floodplain and finish floor
elevations for all insurable structures in the project areas to provide the required proof to FEMA and
mortgage companies This project will greatly reduce the amount of staff time required to assist the
property owners in this area and establish floodplain maps that are reflective of the actual risk of
flooding.
Stormwater staff is also coordinating with Water Department to include a survey of dock and pier
structures in Lake Worth, as well as developing detailed topographic information for use in park and
trail planning. A normal pool elevation contour for Lake Worth will also be created, and emergency
response operations will benefit by identifying the most flood -prone areas. The technology will also
be evaluated as an alternate method of determining impervious cover for utility rate billing. Finally, the
high -resolution elevation data will be used to model existing storm drain systems and feasible
improvements in the Hulen Bend project area.
The Water Department is funding $99,707.00 for the Lake Worth shoreline survey. The survey of the
lake perimeter will include documenting boat dock locations and data to be used during the planning
of the trail system.
Michael Baker Jr. Inc., proposes to perform this project for a lump -sum fee of $427,798.00. Staff
considers this fee to be fair and reasonable for the scope of work proposed, based on the size of the
study areas and the deliverables.
M/WBE - Michael Baker Jr. Inc., is in compliance with the City's M/WBE Ordinance by committing to
24 percent M/WBE participation. The City's goal on this project is 24 percent.
The project is located in COUNCIL DISTRICTS 3, 6 and 7.
FISCAL INFORMATION/CERTIFICATION:
The Financial Management Services Director certifies that upon approval of the above
recommendations and adoption of the attached supplemental appropriation ordinances, funds will be
available in the current operating budget as appropriated, of the Stormwater Utility Fund. Upon
approval, the available cash balance of the Stormwater Fund will be in compliance with the minimum
reserve as outlined in the Financial Management Policy Statements.
