Backbone Storm Drain Construction
Warner to Valencia (CIP 70206) and
City of Tustin, California
n and Testing during Rough Grading and
for Tustin Ranch Road Improvements,
Valencia to Walnut (CIP 70100), Legacy,
INTRODUCTION
At your request, NMG Geotechnical, Inc. (NMG) is pleased to submit this proposal for geotechnical
observation and testing during rough grading and installation of the backbone storm drain associated
with construction of Tustin Ranch Road from Warner Avenue to Walnut Avenue. Our scope of
work and cost estimate is based on: the preliminary project schedule prepared by Parsons
Transportation Group (Parsons) and received by NMG on April 21, 2011; the rough grading and
backbone storm drain plans; our geotechnical report dated February 28, 2011; our familiarity and
prior exploration, grading and construction experience within the former Tustin Marine Corp Air
Station (YMCAs) site and information
The proposed rough grading and improvements for the portion of Tustin Ranch Road (TRR)
from Warner Avenue to Valencia Avenue include portions of the planned roadways for TRR,
Legacy Road, North Loop Road, and Park Avenue, adjacent structural building pads, drainage
basins, and the majority of the backbone storm drain improvement system. The proposed rough
grading and improvements for the portion of TRR from Valencia to Walnut include portions of
TRR and Valencia Road, adjacent structural building pads, drainage basins, Verdura segmental
retaining walls, fill embankments for the TRR bridge over Edinger Avenue, and small portions
of reinforced concrete pipe storm drain improvements. During grading and construction, NMG
will coordinate with the City and Parsons' construction management team to help the contractor
adhere to the geotechnical requirements and bid specifications.
SITE LOCATION AND GRADING HISTORY
The TRR project site is approximately 130 acres and is located on the former Marine Corps Air
Station in Tustin, California. The overall Tustin Legacy site is generally located south of Edinger

Avenue, north of Barranca Parkway, east of Red Hill Avenue and west of Jamboree Road. Since
2004, NMG has closely studied and evaluated the entire Tustin Legacy site.
NMG provided geotechnical observation and testing services during prior demolition of the
majority of the known existing underground improvements and during prior grading of portions
of the former base property, including the southerly Edinger Avenue bridge embankment, the
borrow site area east of the embankment, a future school site in Neighborhood G (offsite) and
Neighborhood E (offsite). Compacted fill surcharges have been constructed and a settlement
monitoring program was implemented for the southerly TRR bridge embankment adjacent to
Edinger Avenue.
PROPOSED ROUGH GRADING AND CONSTRUCTION
The planned grading and improvements will include the following:
• Removal of existing improvements (per plan);
• Remedial and design earthwork to reach rough grade for the subject roadways;
• A structural pad designated as Neighborhood B;
• A structural pad within the loop connector road to Edinger Avenue;
• Three structural building pads along the east side of TRR between Warner Avenue and
Moffett Avenue;
• A borrow site/detention basin area between Moffett Avenue and the loop connecter road;
• A temporary interim detention basin with 64.21 acre feet of storage capacity;
• Temporary earth berms and eight desilting basins throughout the property adjacent to the
road;
• Storm drain reinforced concrete pipe (RCP) and reinforced concrete box (RCB) improvements
along TRR, North Loop Road and Valencia Avenue;
• Anon-structural bio-swale system; and
• Improvements for TRR between Edinger Avenue and Walnut Avenue (TRR extension)
include Verdura segmental retaining walls (Walls A and B), 6- to 12-foot-high block
soundwalls and access roads.
SUMMARY OF GEOTECHNCIAL CONSTRAINTS
The primary geotechnical constraints to the subject grading and improvements include:
• Remedial grading of unsuitable near-surface soils;
• Impact of shallow groundwater to the grading operations, utility installation, roadway
construction, and structural foundations;
110622.doc 2
NMG
10151-02
June 22, 2011
• Deeper removals and excavations that encounter wet soils will require removal bottom
stabilization;
• Trench wall and temporary slope stability during excavation for deep utilities or other
subsurface structures;
• Construction dewatering for deeper excavations;
• Impact of future settlement of the soft clayey soils;
• Construction of the Verdura retaining walls which will require installation of geogrid
reinforcement and select backfill;
• Mitigation of moderately to highly expansive soils; and
• Mitigation of corrosive soils (concrete and metal).
Additional factors that will impact the site development include demolition/abandonment of
existing pavements and utilities, abandonment of groundwater monitoring wells, and removal of
subterranean structures associated with prior land use. Some of the existing utilities and
improvements at the site will also need to be protected in place or adjusted based on the finish
grades.
PROPOSAL ASSUMPTIONS
The following assumptions were made during preparation of this proposal and are applicable to both
sections of TRR (CIP 70206 and CIP 70100):
• NMG will provide pre-construction services, including calculation of remedial earthwork
quantities, site reconnaissance, review of updated groundwater data provided by Pacific States,
coordination with the project civil engineers and bid support. Bid support includes review and
preparation of geotechnical-related project special provisions and technical specifications,
response to bidder's questions, attend team meetings, and communication and coordination
with the project team.
• According to the schedule prepared by Parsons Transportation Group, the rough grading,
Verdura retaining wall construction and backbone storm drain construction will occur
simultaneously and will start July 26, 2011 with a total duration of approximately twelve weeks
(completed October 17, 2011). Please note that for our estimating purposes, we assumed an
additional two weeks due to overlap of grading/construction between both contracts.
• Remedial grading will generally consist of 680,000 cubic yards of remedial removal and
replacement. Remedial earthwork will also include determination of the need for wet removals.
Where wet removals are deemed necessary, evaluation of wet removals and observation of
subgrade stabilization will also be performed.
• Unclassified excavation (estimated) is anticipated to be approximately 325,000 cubic yards.
1 10622doc 3
NMG
10151-02
June 22, 2011
• This proposal does not include observation and testing during excavation and construction of
wet utilities, dry utilities, TRR vehicular bridge and street improvement construction. A
proposal for this work will be provided under separate cover.
• The special inspection and materials testing, as well as environmental services/testing for the
project will be performed by others.
• Laboratory testing during rough grading/improvements will include: maximum density
consolidation/collapse, expansion index, soluble sulfate and sand equivalent.
• The project will be required to follow prevailing wage guidelines.
The following assumptions are applicable to only the section of TRR between Warner and Valencia
(CIP 70206):
• One full-time technician is assumed necessary to evaluate and map removal bottoms, observe
and test placement of compacted fill and complete paperwork during ten weeks of rough
grading operations. Extended days and weekend work are not anticipated.
• Earthwork operations and storm drain construction within the "Special Construction Zone"
(SCZ) will be conducted in accordance with the project specifications pertinent to the SCZ. A
40-hour CaIOSHA-trained senior project technician will be required for earthwork and
construction in the SCZ.
• The subgrade and trench backfill observation and testing during the storm drain construction
will include trench bottom evaluation and stabilization (necessary in most areas), placement of
rock and fabric below the RCP, placement of fabric, rock/aggregate base and soil backfill for
RCB sidewall backfill, shading for RCP storm drain and backfill above the RCB or RCP storm
drain (trench backfill). The backbone storm drain improvements will include:
- The Tustin Ranch Road backbone storm drain will include approximately 3,500 feet of 18 to
84-inch RCP stone drain ranging from 6 to 14 feet in depth (average 6' of cover over RCP)
and approximately 500 feet of various sized additional non-RCP storm drain pipe with soil
cover generally 8 feet deep or less. Stone drain installation will also include approximately
30 transition or junction structures.
- The Tustin Ranch Road backbone storm drain will also include approximately 2,600 feet of
RCB ranging from 4 to 6 feet in height and 5 to 14 feet in width. The RCB soil backfill
cover is generally less than six feet in thickness. RCB construction will also include
approximately ten total inlets, structures or manholes.
- The Park Avenue storm drain improvements will include approximately 700 feet of RCP
with approximately 20 total smaller laterals and inlets. Depth and soil backfill cover over the
pipe is similar to the above depths. Approximately 10 transition or junction structures,
associated with this storm drain, will also be constructed.
- The Park Avenue storm drain improvements will also include approximately 450 feet of 10
foot by 4 foot and 10 foot by 6 foot RCB with cover generally less than six feet in thickness.

The storm drain construction will require observation and testing on a part-time or full-time
basis, dependent upon the schedule and the task occurring.
• One final report for observation and testing during grading (and a separate report for storm drain
improvements are anticipated.
The following assumptions are applicable to only the section of TRR between Valencia and Walnut
(CIP 70100):
• One full-time technician is assumed necessary to evaluate and map removal bottoms, observe
and test placement of compacted fill and complete paperwork during four weeks of rough
grading operations. Extended days and weekend work are not anticipated.
• The Verdura retaining wall construction will include Wall "A", along the east side of Tustin
Ranch Road and Wall "B", along the west side of Tustin Ranch Road. Wall "A" is
approximately 1,000 feet long and ranges up to 23 feet in height at its south end and diminishes
in size as it extends northward. Wall "B" is approximately 1,100 feet in length and ranges up to
12 feet in height at its south end and diminishes in size as it extends northward.
• Site evaluation and laboratory testing to evaluate the 40,000 cubic yards of select import
material for the Verdura Walls. Laboratory tests will include: Sieve, Atterberg Limits, Direct
Shear and Expansion Index.
• Verdura retaining wall construction is anticipated to require approximately six weeks to
complete. Full-time observation and testing will be necessary during wall construction and
backfill.
• The TRR extension storm drain improvements will include approximately 320 linear feet of
RCP with cover generally less than ten feet in thickness.
• We assume that the access roads along the west and east sides of Tustin Ranch Road along the
portion north of Edinger Avenue will be constructed with rough grading improvements. The
access road on the east side consists of approximately 1,600 feet of decomposed granite (DG)
pavement. The access road along the east side consists of approximately 1,200 feet of asphalt
concrete over aggregate base.
• NMG will furnish and install two settlement plates at TRR extension. Installation includes
placement of the steel plate on the removal bottom and coordination with the contractor and site
surveyors, drilling to the settlement plate with abucket-auger drill rig, extension of the
galvanized steel riser pipe and backfill with lean slurry. Engineering evaluation of collected
settlement data and preparation of a settlement release report upon completion of the settlement
waiting period.
• The storm drain construction will require observation and testing on a part-time basis.
• One final report for observation and testing during grading (including Verdura segmental
retaining walls and storm drain improvements) is anticipated.
