Project Understanding - Phase I
wr The City of Tigard Comprehensive Plan Transportation Map identifies Gaarde Street for
extension to Walnut Street,when a direct connection between Scholls Ferry Road and Pacific
Highway will be provided through the extension of Murray Boulevard to Walnut Street and then
to Gaarde Street. Gaarde Street is classified as a Major Collector with a posted speed of 35 mph
and currently carries approximately 8,000 vehicles daily between 121"Avenue and 110th
Avenue. Based on the City of Tigard Public Improvement Design Standards, the roadway
should have a 60 to 80 foot right-of-way with 44 feet provided from curb-to-curb to allow for
three travel lanes (two through lanes plus a center left turn lane). While the City design
standards do not specifically call for bicycle lanes, the 44 feet of paved width will allow for the
three travel lanes plus bike lanes(two 11 foot travel lanes, one 12 foot center left turn lane and
two five foot bike lanes).
Phase I extends Gaarde Street from the northerly boundary of Quail Hollow Subdivision north
through two parcels of property that are owned by the City of Tigard to intersect Walnut Street
approximately 200 feet east of 132nd Avenue. Two homes currently occupy the property and
will be removed for construction of the new street extention. The new Walnut Street/Gaarde
Street intersection requires installation of a traffic signal. A traffic study will be necessary to
++M determine traffic signal needs along the roadway, traffic signal phasing, turn lane needs, and the
length of dedicated turn lanes. Walnut Street is also classified as a Major Collector and
improvements to Walnut Street will be necessary to allow the traffic signal equipment to be
placed in its ultimate location. Along with the widening of Walnut Street at its intersection with
Gaarde Street, an existing vertical curve on Walnut Street east of Gaarde Street will likely
require reconstruction to provide for adequate sight distance at the intersection. It would be
desirable to reconstruct Walnut Street for at least 300 feet in each direction of Gaarde Street such
that the vehicle detection and conduit associated with the new traffic signal can be installed in its
.r
ultimate location, thereby minimizing (or eliminating)the need for traffic signal modifications
during the Washington County MSTIP 3 improvement project along Walnut Street
Storm water improvements will utilize the Unified Sewerage Agency guidelines for surface
water runoff incorporating existing piping where possible. Surface runoff from the
improvements will be collected, detained and possibly treated prior to discharge into the existing
.r drainage pattern in the area. Street profiles from the extension of Gaarde through Quail Hollow
Subdivision indicate that the runoff will travel north to Walnut for discharge. A deeply incised
.drainage channel located directly adjacent to the southern terminus of the project is proposed to
dw utilize a large diameter pipe to carry flows.
Underground utility lines excluding storm drainage includes a new 12-inch pipe from Walnut to
the Quail Hollow Subdivision to complete a loop. Sanitary sewer is not anticipated to be
required within this section of Gaarde.
.. All remaining utilities including electrical, telephone, cable, etc. will be installed underground by
the respective companies.

Scope of Work
Century West will perform services on the project orientation, preliminary design, final design
and construction staking phases of this project. A fee schedule is provided for the project based
upon the following Scope of Services.
Task 1 - Project Orientation (June 10, 1999 )
■ Review technical data supplied by City along with policy and procedure manual at a meeting
concluded by a field visit to the project site.
■ Obtain all record drawings of existing City utilities including topographic maps, aerial photos,
tax maps, owner-ship reports and review for preliminary design.
Task 2 - Preliminary Engineering (.lune 14, 1999-August 1, 1999)
This phase includes up to 60% design completion and is divided into several individual work
items to successfully complete the project.
2.1 Field Location Survey
■ Research and gather surveys of record and County road records filed with the County
Surveyor for existing right-of-way identification.
■ Obtain existing deed and legal descriptions of the properties within the project areas.
■ Call on (in person if possible) and send notices to all adjoining property owners or residents
and notify them that we will be surveying in the area and the purpose of our survey.
■ Establish horizontal and vertical control networks and locate and tie existing monuments that
can be found. The work to complete this task is not a boundary survey.
■ Conduct topographic survey making ties to all utilities, curbs, pavement edges, street
" centerline, buildings within 50 feet of the right-of-way, trees, shrubs and landscape features,
driveways, power/utility poles and other features which may affect the design along Gaarde
from the intersection of 132nd east a distance of approximately 600 feet. Other areas to be
surveyed include the extension of Gaarde through a strip of undeveloped property recently
purchased by the City of Tigard and along Walnut both east and west of the proposed new
intersection. -
■ Prepare a detailed topographic map which includes the following limits within the existing
right-of-way and property previously identified. Gaarde; extention of SW Gaarde from the
terminus of Quail Hollow Subdivision to the intersection of Walnut, a distance of
approximately 650 feet; Walnut from the intersection of SW 132nd Avenue east a distance of
approximately 600 feet.
irr
2.2 Subsurface Investigation
■ A Geotechnical Report presenting our interpretation of the subsurface conditions together with
n our recommendation with respect to asphalt pavement thickness design will be provided.
■ To evaluate the subsurface conditions, three shallow borings are proposed within the road
alignment made with a trailer mounted drill rig. One of the borings will be made in the
segment just south of Walnut. The borings will vary from five to 25 feet, depending upon
location. The borings will be deeper where cuts or fills are anticipated. All samples obtained
from the borings will be examined in the laboratory to verify the field classifications with in-
place densities to be determined. A representative bulk sample will be tested to determine the
moisture-dry density relationship and CBR strength of the subgrade soils for subgrade
compaction and pavement support characteristics.
■ Upon completion of our explorations, laboratory tests and engineering studies, a Geotechnical
Report will be provided for determination of stable cut and fill slopes, embankment settlement
and to determine economical pavement sections using the AASHTO pavement design methods.
Traffic counts and a breakdown of anticipated vehicular types shall be provided by the City
for use in this report.
2.3 Preliminary Engineering Design
.+. ■ Prepare preliminary base maps at horizontal scale of one inch equals 20 feet. Total length of
improvements are assumed to be completed within the dimensions identified in Section 2.1,
Paragraph 6.
■ Prepare preliminary design of storm drain pipes and catch basins using Chapter 3 of the USA
design manual for surface water. Determine if adequate capacity exists in drainage system
immediately down-stream which may require some form of on-site detention for the 25 year
design storm.
.. ■ Prepare preliminary street design plans within the project based upon a Major Collector street
wide of 44 feet using a design speed of up 35 mph utilizing topographic survey data and
Softdesk design software. Additional right-of-way on Gaarde and Walnut will be identified.
The limits of work on Walnut will be within the 600 foot section surveyed to accommodate
sight distance restrictions and vehicle detector loop installations.
■ Prepare preliminary design alternatives within the project based upon various street widths and
vertical curves using design speeds of up to 35mph. A minimum of two conceptual
alternatives utilizing topographic survey data and Softdesk design software will be used
showing additional right-of-way for the new vertical curves and the widened street section
with the use of retaining walls where necessary. Upon completion of the layouts, Preliminary
Design Memo will be provided identifying the various options. Following review by City
staff, preliminary design of the selected alignment will be initiated. Additional right-of-way
■■ to construct the improvements can be easily identified at this time. Legal descriptions for
acquisition of this property or miscellaneous easements greater than the estimated number will
also be negotiated as additional services. For estimating purposes a total of 10 parcels of
property are assumed to require easements within Phase I.
`. ■ Meet with the CIT (Citizens Involvement Teams) to present the recommended alignment from
City review and to discuss impacts to local residents. Conduct two neighborhood meetings
with property owners for each Phase to solicit input during preliminary design and addressing
these concerns in a proactive manner to increase public support of the project.
■ Prepare preliminary erosion control plan.
■ Prepare preliminary tree planting plan for any areas that have sufficient width within the right-
of-way. City approved tree standards will be followed in selection. This will not include
subsurface irrigation for plant establishment.
■ Prepare itemized quantity estimates, quantity summary and cost estimates for all aspects of the
improvements.
2.4 Preliminary Lighting Design
■" ■ Provide suitable light levels with new poles and luminaries to safely move pedestrians and
vehicles through the new improvements.
+r ■ The basis for roadway lighting design shall be the "Roadway Lighting Handbook" by the
FHWA. Specifications and lighting design will conform to ODOT Standard Specifications for
Highway Construction and will meet the requirements of the City of Tigard.
2.5 Preliminary Traffic Engineering
■ Meet with City traffic engineering staff to coordinate requirements.
■ Prepare a detailed traffic engineering analysis which includes a traffic signal warrant analysis
for the Gaarde/Walnut intersection. New 24-hour tube counts with speed data will be
necessary on Walnut at Gaarde to conduct the signal warrant analysis. Traffic demand on
Gaarde at Walnut will be estimated by using the City's travel demand model developed by
DKS for work on the City's Transportation System Plan.
■ Other traffic engineering elements to be determined include: the need for left turn and/or right
turn pockets at the Gaarde/Walnut intersection; the sight distance needs at the intersection; the
length of the turn pockets (if any); and construction staging for the project.
■ Signing and striping plans will be developed along Gaarde with an emphasis on protecting
pedestrians and bicycles. These plans will meet Manual of Uniform Traffic Control Devices
standards.
■ Traffic control will be described through the use of special provisions to the contract
documents and detailed drawings.
irr
Task 3 - Final Design (August 15, 1999 -October 15, 1999)
Task 3 includes 60% to 100% completion and bid period services. It involves the following
„ issues:
■ Incorporate items identified in the City's review of the drawings and specifications.
■ Revise the quantity estimate, summary of the quantity estimate and cost estimate.
■ Provide ROW and easement descriptions and maps for property acquisition including right-of-
way, slope and construction easements. These will be prepared on City forms suitable for use
in negotiations with the property owner. The maps will show property lines and a few easily
referenced items such as existing edge of pavement or other features the property owner can
easily identify. A total of 10 parcels of property adjacent to Walnut are estimated to require
one or more legal descriptions.
"" ■ Complete lighting design, signing and striping plan along with traffic control plan.
■ Write special provisions to the City of Tigard Standard Construction Specifications as
necessary to provide a description of the work required and method of payment for all items
of work and to clarify construction details.
• Task 4 - Bid Period Services (Spring 2000)
■ Answer bidder's questions at the pre-bid meeting.
■ Assist the City in clarifying the intent of the contract documents for the bidders and prepare
text for any needed addenda
■ Conduct a pre-construction conference with the City, Contractor and all applicable utility
agencies which will be affected by the construction
Task 5 - Construction Staking (summer 2000)
■ Provide one set of construction stakes for street improvements within limits of project
identified under 2.1 including clearing limits, rough-cut grade, curb, storm drainage and
do waterline. The fee provided must still be refined when all of the improvements are designed.
■ Provide a road monument survey with Washington County Surveyor and provide a copy to
the City after construction is complete. Prior to construction also file with County a record
of survey map showing locations of existing corners, which may be disturbed or destroyed
during construction with a copy to the City.

�. REVIEW / CHECKING
The quality of work on this project is important. The Gaarde Street project is the second
opportunity for Century West to work with the City of Tigard on a street project during the last
year. Consequently, if we meet their expectations and deliver a quality project, there exists a
good chance of being selected for future projects of this same nature. Thus, the project team
must strive for excellence on this project.
It is the responsibility of Century West to inform its employees of the expectations of quality
placed on their work. This has been done with the Quality Assurance/Quality Control
(QA/QC) Manual. Please review this resource before and during the project such that you are
familiar with it. When in doubt of the expectations of Century West or the client, please consult
the Project Manager, Ron Weigel, for more direction.
The QA/QC review will be performed by Matt Hall. He has extensive experience in this type of
engineering work. He will perform an independent review during various stages of the project
and complete and in-depth 90 percent review of the plans and specifications. His review and
resulting revisions will be conducted prior to submittal to the City of Tigard for their review.
