RE: Rancho Santa Fe Road Realignment-Final Preliminary Engineering
Dear Doug:
Dokken Engineering is pleased to submit Milestone 4 for the Rancho Santa Fe
Road Realignment Project. Milestone 4, the fourth of four milestones, is the final
submittal for Design Stage 1. With this submittal, preliminary engineering has
been completed for the Rancho Santa Fe Realignment Project. Milestone 4 consists
of resubmittal of all previous Design Stage 1 project components with resolution of
all outstanding project issues.
Project components included herewith are substantially the same as that
previously submitted in Milestones 1, 2 & 3. Project components that have been
revised over the course of Design Stage 1 development are summarized on the
following page.
We have enjoyed working with the City of Carlsbad on Design Stage 1, preliminary
engineering for Rancho Santa Fe Road Realignment. We look forward to future
involvement with the City in Design Stage 2 as we complete Plans, Specifications
and Estimates for Phase I Construction.
If you require any additional information, or have any questions, please do not
hesitate to call us.
Sincerely,
Richard T. Lij^^

Project Component Evolution and Revisions
Profile for Rancho Santa Fe Road, shown on Geometric Approval Drawing, was revised for
Milestone 2 from initial submittal with Milestone 1. Profile was revised for several reasons:
Profile was raised slightly (approximately 2') in vicinity of 199+00 'RSF' to reduce height of cut
slope in order to minimize potential impact with overhead power poles on east side of alignment.
Profile was lowered slightly (approximately 4') in vicinity of 256+00 'RSF' to allow better
intersections tie-in grades with proposed realigned Questhaven Road. Profile was lowered slightly
(approximately 0.7') in vicinity of 281+00 'RSF' to allow for better connection with profile
developed for City of San Marcos improvements to Rancho Santa Fe Road north of Melrose
Drive.
Interim Conditions Drainage Plan was revised for this submittal from initial submittal with
Milestone 3. Interim Conditions Drainage Plan submitted with Milestone 3 showed concrete
drainage inlets being built to full dimensions at ultimate curb line locations. Revised drainage
plan shows drainage inlets being built at ultimate curb line locations, however they will not be
constructed to full dimensions. Winged portions of Type B inlets will not be constructed and a
modified Type G Inlet top will be constructed. This change will result in cheaper initial
construction costs for the City and allow for better surface drainage for interim conditions until
outside lanes are constructed.
Also shown on Interim Conditions Drainage Plan, included in this submittal, is the addition of
AC paved ditches located at approximate ultimate curb line locations. AC paved ditches will help
to convey storm water to drainage inlets from cut slopes and 'bench" areas created for fiimre
outside lane construction. Engineers Estimate(s) has been revised to reflect this addition to
project.
Long Term Detour Alignment and Profile for Altemative A, Scenario 1, has been revised since
initial submittal with Milestone 1. Altemative A, Scenario 1 assumes 'top of hill' phase boundary
and construct Phase I first. Alignment has been revised to eliminate conflicts with existing 12"
water line and to help minimize earthwork necessary for detour constmction. Revised alignment
and profile is included in 'Phasing' portion of this submittal. Horizontal stopping sight distance
calculations for revised alignment are included in sight distance portion of this submittal.
Utility Relocation Maps were revised for Milestone 3 from initial submittal with Milestone 2.
Revisions added existing utilities not previously shown with Milestone 2 submittal.

Topographic Mapping
Three-dimensional topographic mapping was developed exclusively for
use with this project utilizing the latest aerial photogrametric mapping
techniques. The project corridor was flown and photographed February 28,
1998. This information was used to develop 3-D contours, a digital terrain
model (dtm) and a triangulated irregular network (TIN) model. The TIN
model was used in conjunction with roadway design software to perform
earthwork analysis found elsewhere in this report.
Horizontal control for this project was established using static
Global Positioning System (GPS) surveying from County Of San Diego
High Precision Geodetic Network (HPGN) control monuments 'Lomax'
and 'Ca 11 07*, as shown on Record of Stirvey 14310. Additional
monuments, as shown on Record of Survey 13928, were also incorporated
into the network. A level circuit was run using County Of San Diego
Bench Mark K-302 as the vertical reference. This datum was used on
Record of Survey 13928. The data was then reduced and the values used
for subsequent Real Time Kinematic (RTK) surveying of the aerial
control.
DOKKEN
ENGINEERING
Topographic field surveys to supplement aerial mapping were also
performed to cross-section San Marcos Creek. This information will be
used in the study of creek hydraulics in the vicinity of planned Rancho
Santa Fe Road bridges over San Marcos Creek.

Geometries
City of Carlsbad Circulation Element lists Rancho Santa Fe Road
as a prime arterial roadway. City of Carlsbad Design Manual lists the
design speed for a prime arterial at 60mph with a minimum centerline
radius of 2400'. The minimum centerline radius of 2400' assumes a
normal crown slope. In areas where a 2400' radius is not provided, the
roadway will be superelevated. The city Design Manual lists the maximum
profile grade for a prime arterial as 7%, and a maximimi profile grade of
6% where the prime arterial crosses an intersecting roadway. Because
Rancho Santa Fe Road is plaimed to have intersecting roadways within the
limits of this project, the maximum grade on Rancho Santa Fe Road is
proposed to be 6%.
Proposed Rancho Santa Fe Road is planned to tie into existing
Rancho Santa Fe Road south of La Costa Avenue. Tie to existing Rancho
Santa Fe Road will occtar approximately 800' south of La Costa Avenue at
a point where Rancho Santa Fe Road has been widened to ultimate
conditions (SDP 86-03A conditions property owner at SE comer of
Rancho Santa Fe Road and La Costa Avenue to construct improvements
adjacent this property). As proposed Rancho Santa Fe Road progresses to
DOKKEN
ENGINEERING
the north, horizontal alignment and vertical profile have been developed to
conform to previous alignment and profile developed by Project Design
Consultants (PDC). Conformance with PDC alignment and profile was
considered appropriate in part due to adjacent property owners previously
utilizing PDC alignment to develop master plans for their properties.
The proposed alignment is slightly easterly of the PDC alignment
in the vicinity of Mahr Reservoir. As proposed Rancho Santa Fe Road
approaches northem project limits, horizontal alignment has been
developed to tie into planned improved Rancho Santa Fe Road currently
being designed by City of San Marcos. Rancho Santa Fe Road plans
currently being developed by San Marcos will connect directly to City of
Carlsbad's Rancho Santa Fe Road, with Melrose Drive being realigned to
coimect to proposed Rancho Santa Fe Road as one leg of a fotir-leg
intersection.
Profile grade for Rancho Santa Fe Road in vicinity of San Marcos
Creek has been developed in accordance with findings foimd in San
Marcos Creek hydrology study and bridge hydraulics study. These studies
entitled "Hydrology Study for San Marcos Creek at Rancho Santa Fe
Road" and "Hydraulic and Scour Studies for Proposed Rancho Santa Fe
Road Bridge on San Marcos Creek" were developed for use with this
DOKKEN
ENGINEERING
project by Howard Chang Consultants and transmitted to the City of
Carlsbad under separate cover. These reports reached conclusions on
stream discharge and water surface elevations for a 100-year storm event
in San Marcos Creek at Rancho Santa Fe Road. 100-year storm water
surface elevations were used to help set bridge soffit elevations to insure a
100-year storm would pass under the planned stmcture. 100-year storm
water surface elevations were also used to set grades on Rancho Santa Fe
Road north of San Marcos Creek so that roadway will not flood during a
100-year storm event.
Table below summarizes curve data for the six horizontal curves
proposed for Rancho Santa Fe Road. Horizontal curves with radii less than
2400' will be superelevated at 2% and will require variance due to their
non-standard curve radii.

Sight Distance Calculations
Horizontal stopping sight distance for this project has been
evaluated utilizing standards set forth in the Califomia Department of
Transportation Highway Design Manual, July 1990 edition.
Vertical sight distance has been evaluated utilizing Eagle Point
Roadway Design Software, in conformance with AASHTO standards.
The attached sight distance calculations are intended to identify
areas where the city prescribed 60mph design speed criteria for a prime
arterial cannot be maintained. Reasons for not being able to maintain
60mph design speeds will be identified and the use of non-standard design
speeds will be justified.
There are two horizontal ctirves on the proposed alignment where
the 60mph design speed cannot be met. At the first location, Curve 1, the
proposed Rancho Santa Fe Road ties into existing Rancho Santa Fe Road
south of La Costa Ave. This 1500' radius curve provides a 55mph design
speed for stopping sight distance. The majority of this curve is within a
portion of Rancho Santa Fe Road that is currently widened to its ultimate
condition. The radius of this existing curve was established at a time when
Rancho Santa Fe Road was classified as a major arterial. Rancho Santa Fe
Road was subsequently upgraded to prime arterial status by the city.
DOKKEN
ENGINEERING
At the second location, Curve 6, the proposed Rancho Santa Fe
Road approaches Melrose Drive from the south. This 1400' radius curve
provides a 55mph design speed for stopping sight distance. A 60mph
design speed cannot be achieved here without additional right of way
purchase by the city, or realignment of proposed roadway to the west.
Realigning the road to the west will result in increased rock excavation in
vicinity of proposed SB bridge abutment 1, and could also result in
increased environmental impacts by bridge in wetlands within creek
channel. The proposed curve is to be superelevated at a rate of 2%
maximum cross-fall.
There is a single vertical curve on the proposed alignment where
the 60mph design speed cannot be maintained. Sag vertical Curve 6,
which is the vertical curve between the proposed bridge over San Marcos
Creek and the intersection with Melrose Avenue has a design speed of just
imder 55mph, about 54mph. The length of this vertical curve and the
ahead tangent grade on this vertical curve are restricted due to the
requirement to tie into existing Rancho Santa Fe Road, or City of San
Marcos improved Rancho Santa Fe Road, near Melrose Avenue. Design
speed for sag vertical curves are govemed by headlight sight distance and
could be improved in this area with appropriate street lighting. In this area
the vertical and horizontal alignment maintain consistency, each with a
design speed of near 55mph.

Project Phasing
The Rancho Santa Fe Road realigimient project has been proposed
by the city to be built in two construction phases. Phase I construction will
build Rancho Santa Fe Road from La Costa Avenue toward the north;
Phase 11 will build Rancho Santa Fe Road from Melrose Avenue to the
south. It is possible Phase II will precede Phase I to construction.
Two scenarios have been analyzed for this project. Scenario 1
assumes Phase I precedes Phase II to construction. Scenario 2 assumes
Phase II precedes Phase I to construction. Each scenario considers two
altematives, Altemative A and Altemative B, for long-term transitions
between existing Rancho Santa Fe Road and proposed Rancho Santa Fe
Road.
For each scenario, the Altemative A phasing boundary is adjacent
to Mahr Reservoir, near the high point of original ground on the proposed
Rancho Santa Fe Road alignment. For each scenario, the Altemative B
phasing boundary is near where the proposed Rancho Santa Fe Road
aligmnent crosses the existing Rancho Santa Fe Road aligimient.
Attached exhibits show Altemative A and Altemative B plans and
profiles of long-term detours for each scenario. In the event Phase I and
Phase II are awarded as one contract, these altematives will be used to
help develop traffic handling plans for stage construction.
DOKKEN
ENGINEERING
Phase Boundary Recommendations
Factors considered when determining best location for the Phase I / Phase
II boundary were:
• Long-term detour alignment and profile
• Earthwork balancing between Phase I and Phase II
• Cost of detour construction
• Environmental Considerations
Altemative B, with the Phase I / Phase II boundary near where
proposed Rancho Santa Fe Road crosses the existing Rancho Santa Fe
Road (approximate Sta. 254+00 'RSF' line) is the recommended
boundary. This boundary is the preferred boundary no matter which phase
is constructed first. Altemative B surpasses Altemative A in all factors
considered.
Altemative B alignment for each scenario is much shorter with a
smoother profile than Altemative A for each scenario. As shown in the
earthwork analysis found elsewhere in this submittal, balancing between
Phase I and Phase II construction will be more easily accomplished with
the Altemative B phasing boundary. Earthwork required for Altemative B
DOKKEN
ENGINEERING
detour constmction for each scenario would be less than Altemative A for
each scenario. Therefore, detour constmction costs will be less. Also,
Altemative B detour construction will be more environmentally acceptable
than Altemative A detour because Altemative B detour does not encroach
upon the habitat protection area.

Earthwork Analysis
Excavation and embankment quantities were calculated with
Geopak Roadway Design Software and a three-dimensional digital terrain
model developed for this project by PhotoGeodetic Corporation and
Lintvedt, McColl & Associates.
Earthwork was analyzed under three different cases. Case I
analyzed earthwork volumes over the entire length of proposed Rancho
Santa Fe Road (La Costa Avenue to Melrose Avenue).
Case II analyzed earthwork volumes with the assumption the Phase
I / Phase II boundary is adjacent to Mahr Reservoir (proposed Rancho
Santa Fe Road Sta 232+00 'RSF' line).
Case III analyzed earthwork volimies with the assumption the
Phase I / Phase II boundary is near where proposed Rancho Santa Fe Road
crosses existing Rancho Santa Fe Road (proposed Rancho Santa Fe Road
Sta 254+00 'RSF' line). Phase I is the south portion of the project and
Phase II is the north portion of the project.
Case I earthwork analysis calculated the earthwork volumes
required to complete the entire proposed Rancho Santa Fe Road
Realignment Project at 818,000 CY of excavation and 630,000 CY of
embankment. The profile grade for Rancho Santa Fe Road has been

ENBINEERING
designed to optimize the earthwork balance while still providing no greater
than the maximum grade of 6% for a prime arterial roadway through all
intersections. The excess material generated with this project will be
wasted on-site in a city approved disposal area.
Case II earthwork analysis assumes the Phase I / Phase II boundary
is adjacent to the Mahr Reservoir, near the high point of the original
ground on the proposed alignment. Phase I earthwork quantities have been
calculated at 681,000 CY of excavation and 286,000 CY of embankment.
Phase II earthwork quantities have been calculated at 137,000 CY of
excavation and 344,000 CY of embankment.
If Phase I is constmcted prior to Phase II, 207,000 CY of material
will need to be stockpiled and brought forward in Phase II to complete
embankment constmction. If Phase II is constmcted prior to Phase I,
207,000 CY of material will need to be borrowed from the southem
portion of the project to complete the embankment north of the reservoir.
Case III earthwork analysis assumes the Phase I / Phase II
boundary is near where the proposed Rancho Santa Fe Road crosses the
existing Rancho Santa Fe Road. Profile grades of the proposed and
existing alignments of Rancho Santa Fe Road cross within 3 ft of each
other at this location. Phase I earthwork quantities have been calculated at
DOKKEN
ENGINEERING
789,000 CY of excavation and 519,000 CY of embankment. Phase II
earthwork quantities have been calculated at 29,000 CY of excavation and
111,000 CY of embankment.
If Phase I is constmcted prior to Phase II, 82,000 CY of material
will need to be stockpiled and brought forward in Phase II to complete
embankment constmction. If Phase II is constmcted prior to Phase I,
82,000 CY of material will need to be borrowed from the southem portion
of the project to complete the embankment in Phase II.

San Marcos Creek Hydrology
A hydrology study was prepared to provide the discharges for
floods of different frequencies for San Marcos Creek at Rancho Santa Fe
Road. The existing Rancho Santa Fe Road Bridge on San Marcos Creek
does not have adequate capacity for passing the 100-yr flood; therefore,
this bridge will be replaced as a part of the Rancho Santa Fe Road
improvement project.
A previous hydrology smdy for San Marcos Creek was made by
the U.S. Army Corps of Engineers in 1971. Peak flows for intermediate
regional flood for San Marcos Creek at Rancho Santa Fe Road from the
1971 study is summarized below. The intermediate regional flood is one
that could occur about once in 100 years on the average. In other words,
the intermediate regional flood is equivalent to the 100-yr flood.
Intermediate Regional Floods obtained by Corps of Engineers
San Marcos Creek Location Intermediate Regional Flood
Rancho Santa Fe Road 13,000 cfs
The hydrology study by the Corps of Engineers was made at a time
before the master plan of development for the region was available. For
DOKKEN
ENGINEERING
this reason, the study was for the physical conditions of the drainage basin
existing at the time of study but it does not reflect the physical conditions
when the drainage basin is ftilly developed.
The proposed Rancho Santa Fe Road will serve the region for a
long time in the future. It is therefore necessary to design the bridge based
on the ultimate 100-yr flood for the fully developed conditions of the
drainage base for San Marcos Creek. The hydrology study was made to
determine the ultimate flood discharges based on the master plan for future
development on the drainage basin of the creek. The flood discharges of
San Marcos Creek at Rancho Santa Fe Road obtained from this study are
simmiarized below. The completed report entitled "Hydrology Study for
San Marcos Creek at Rancho Santa Fe Road" has been transmitted to the
City of Carlsbad imder separate cover.

RG: Rancho Santa Fe Road Realignment - Engineers Estimate
City of Carlsbad Project 3190
Dear Doug:
Please find attached the Engineers Estimate of cost for above referenced project.
This estimate has been prepared at a preliminary engineering design stage and
includes a contingency of 15%. Also shown are an estimated 12% design fee and
15% construction administration fee.
Attached are two plots (Altemative A and Alternative B) showing different
geographic zones for which the project has been broken into for purposes of
assignment of costs, construction phasing, and funding source identification. The
geographic zone dividing lines are based upon factors such as: timing of proposed
construction; construction in Tiabitat protection area'; phase boundary between
Phase I construction and Phase II construction; and HBRR funding area.
Altemative B geographic zones assume phase boundary is at ^crossover' where
proposed Rancho Santa Fe Road crosses over existing Rancho Santa Fe Road near
proposed Rancho Santa Fe Road station 254+00 *RSF. Altemative A geographic
zones assume phase boundary is at 'top of hill' location, adjacent Mahr Reservoir
and by high point of proposed Rancho Santa Fe Road alignment near station
225+40 'RSF (see Milestone 1 submittal, 'Phasing'). Descriptions of Altemative
B geographic zones are as follows:
Zone I consists of improvements to Rancho Santa Fe Road south of La Costa
Avenue (159+00 to 165+80 'RSF'). This area has been broken into a separate
zone because the City of Carlsbad has determined the property owner at the
southeast corner of Rancho Santa Fe Road and La Costa Avenue is
responsible for the widening of Rancho Santa Fe Road adjacent their
property. Also, it is considered likely this portion of Rancho Santa Fe Road
will be widened prior to the realignment of Rancho Santa Fe Road.

Zone 2 consists of realignment of Rancho Santa Fe Road between La Costa
Avenue and begin ^habitat protection area' (165+80 to 217+00 'RSF'). This
area has been broken into a separate zone due to its location adjacent the
*habitat protection area'. It is considered likely the property east and west of
Rancho Santa Fe Road within Zone 2 will eventually be developed. Because
this area will be eventually developed it is anticipated the initial
construction of Rancho Santa Fe Road will include only 2 NB lanes and 2 SB
lanes, with the remaining 1 NB and 1 SB lane constructed as the adjacent
land develops.
Zone 3 consists of realigned Rancho Santa Fe Road within 'habitat
protection area' (217+00 to 237+00 *RSF'). This area has been broken into a
separate zone because property east and west of realigned Rancho Santa Fe
Road will not be developed. Becaiise adjacent property will not be developed
it is possible initial construction of Rancho Santa Fe Road will include
building this portion of roadway to its ultimate width of 3 NB lanes and 3
SB lanes.
Zone 4 consists of reaHgned Rancho Santa Fe Road between end 'habitat
protection area' and 'crossover' phase botmdary location (237+00 to 254+00
'RSF). This area has been broken into a separate zone due to its location
between the 'habitat protection area' and 'crossover* phase boundary. The
northem limit of Zone 4 has been chosen at station 254+00 'RSF' because it
will be the approximate location of end constmction in Phase I constmction
contract for Alternative B. It is considered likely the property east and west
of Rancho Santa Fe Road within Zone 4 will eventually be developed.
Because this area will be eventually developed it is anticipated the initial
constmction of Rancho Santa Fe Road will include only 2 NB lanes and 2 SB
lanes, with the remaining 1 NB and 1 SB lane constmcted as the adjacent
land develops.
Zone 5 consists of realigned Rancho Santa Fe Road between 'crossover'
phase boundary and proposed bridge federal funding limits (254+00 to
268+32 'RSF). The southem limits of Zone 5 (254+00 'RSF) has been chosen
because it will be the approximate location of begin constmction in Phase II
constmction contract for Altemative B. The northem limits of Zone 5
(268+32 'RSF') has been chosen due to its location at 200' south of begin
Rancho Santa Fe Road bridges over San Marcos Creek. 200' is the normal
approach length for which federal funding is available for HBRR projects.
Zone 6 consists of reaHgned Rancho Santa Fe Road within vicinity of
proposed bridges over San Marcos Creek and includes bridges (268+32 to
276+00 'RSF). The southem and northem hmits for this zone have been
chosen to include proposed stmctm-es and 200' of approaches from begin and
end bridges. 200' is the normal approach length for which federal funding is
available for HBRR projects.
DOKKEN
ENGINEERING
Zone 7 consists of realigned Rancho Santa Fe Road between northem
HBRR funding limits and proposed realigned Melrose Drive (276+00 to
284+20 'RSF). The northem limit for this zone has been chosen at location
of proposed realigned Melrose Drive because it is likely all improvements for
Rancho Santa Fe Road north of realigned Melrose Drive will have been
completed by City of San Marcos prior to Phase II constmction.
Zone 8 consists of realigned Rancho Santa Fe Road north of proposed
reaHgned Mefrose Drive (284+20 to 295+00 'RSF'). This area has been
broken into its own zone because it is considered Hkely this area of roadway
will have been improved by the City of San Marcos prior to Phase II
constmction. Northern limit of Zone 8 has been chosen to adequately
transition realigned Rancho Stmta Fe Road into existing Rancho Santa Fe
Road north of proposed realigned Melrose Drive.
Descriptions of Altemative A geographic zones are as follows:
Zone I consists of improvements to Rancho Santa Fe Road south of La Costa
Avenue (159+00 to 165+80 *RSF). This area has been broken into a separate
zone because the City of Carlsbad has determined the property owner at the
south-west comer of Rancho Santa Fe Road and La Costa Avenue is
responsible for the widening of Rancho Santa Fe Road adjacent their
property. Also, it is considered likely this portion of Rancho Santa Fe Road
will be widened prior to the realignment of Rancho Santa Fe Road.
Zone 2 consists of realignment of Rancho Santa Fe Road between La Costa
Avenue and begin 'habitat protection area' (165+80 to 217+00 'RSF). This
area has been broken into a separate zone due to its location adjacent the
'habitat protection area'. It is considered likely the property east and west of
Rancho Santa Fe Road within Zone 2 will eventually be developed. Because
this area will be eventually developed it is anticipated the initial
constmction of Rancho Santa Fe Road will include only 2 NB lanes and 2 SB

This area has been broken into a separate zone because property east and
west of reaHgned Rancho Santa Fe Road will not be developed. Because
adjacent property wiU not be developed it is possible initial constmction of
Rancho Santa Fe Road will include building this portion of roadway to its

268+32 'RSF). The southem limits of Zone 4 (225+40 'RSF) has been chosen
because it will be the approximate location of begin constmction in Phase II
constmction contract for Altemative A. The northem limits of Zone 5
(268+32 'RSF) has been chosen due to its location at 200' south of begin
Rancho Santa Fe Road bridges over San Marcos Creek. 200* is the normal
approach length for which federal funding is available for HBRR projects.
Zone 5 consists of realigned Rancho Santa Fe Road within vicinity of
proposed bridges over San Marcos Creek and includes bridges (268+32 to
276+00 *RSF). The southem and northem Hmits for this zone have been
chosen to include proposed stmctiu^s and 200' of approaches from begin and

available for HBRR projects.
Zone 6 consists of reaHgned Rancho Santa Fe Road between northem
HBRR funding limits and proposed realigned Melrose Drive (276+00 to
284+20 'RSF). The northem Hmit for this zone has been chosen at location
of proposed realigned Melrose Drive because it is likely aU improvements for
Rancho Santa Fe Road north of reaHgned Melrose Drive will have been
completed by City of San Marcos prior to Phase II constmction.
Zone 7 consists of realigned Rancho Santa Fe Road north of proposed
realigned Mebose Drive (284+20 to 295+00 'RSF). This area has been
broken into its own zone because it is considered likely this area of roadway
will have been improved by the City of San Marcos prior to Phase II
constmction. Northem Hmit of Zone 8 has been chosen to adequately
transition realigned Rancho Santa Fe Road into existing Rancho Santa Fe
Road north of proposed realigned Melrose Drive.
The Engineers Estimate has been broken into seven different estimate schedules.
Assumptions used in the development of these different schedules are listed below.
Summaries of the seven different estimate schedules are as foUows:
Schedule A: Schedule A Engineers Estimate of costs consists of constmction costs
associated with widening and reaHgnment of Rancho Santa Fe Road between La
