Municipal Code §2.36.050(a)(6) and adopt resolution approving the
Memorandum of Agreement with the City of Livermore, City of
Pleasanton, and Alameda County Flood Control & Water
Conservation District Zone 7 regarding sharing the costs for services

2) Adopt resolution approving Consulting Agreement between
the City of Dublin, City of Livermore, City of Pleasant on, Alameda
County Flood Control & Watcr Conservation District Zone 7, and
HJW Geospatial, Inc. for aerial orthophotography services.
The total project cost submitted by the selected aerial contractor,
HJW, is $324,700.00 if the aerial orthophotography for the
participating agencies are taken in a single flight. Dublin's estimated
share is $53,199.44. The project will be charged to CIP Geographic
Information System 93192. Sufficient funds are included in the Fiscal
Year 2004-2005 CTP budget to complete the project.
DESCRIPTION: The City of Dublin has been actively engaged in the developmcnt of a
Geographic Information System (GIS) that will serve the City's Staff and community. Digital imagery
provides critical backdrop imagery to the City's on-line GIS and to most cartographic products. This digital
imagery is more than an enhancement; it is a system requirement. The City of Dublin has a unique
opportunity to acquire up-to-date digital orthoimagery at significant cost savings.

C/
The City of Livermore, City of Pleasant on, and Alameda County Flood Control & Water Conservation
District Zone 7 (Zone 7) require new imagery that would overlap with the City of Dublin's boundary. The
City of Dublin was invited to join a group purchase of aerial imagery for the Dublin-Livermore-Pleasanton
area. By using a data sharing agreement and dividing costs proportionally between the City of Livermore,
City of Pleasanton, and Zone 7, the City of Dublin can acquire imagery for the entire Dublin area at a
significantly reduced cost of $53, 199.44. Tfthe City were to engage HJW separately to conduct aerial
photography ofthe Dublin area the cost would be $102,401.68.
Because each agency will rcccive data from the entire flight area (which includes Zone 7, Pleasanton, and
Livermore), all projcct costs, estimated at $324,700.00 will be shared equally, with each participant paying
a portion based on its geographic size. As a result, Dublin is realizing a savings of $49,202.24 (48%).
It is advantageous for the City to enter into the MOA with thc City of Livermore, City of Pleasant on, and
Zone 7 to share the proposed costs and resulting data and realize the significant cost savings achieved when
all parties cqually participate in an expensive data collection project.
In most cases, the City's Purchasing Ordinance requires that major purchases be subject to the competitive
bid process. However, the Dublin Municipal Code §2.36.050 (a)(6), provides the following exception
from the competitive bid process: "When a purchase involves goods of a technical nature, where it would
be difficult for a vendor to bid on a standard set of specifications, the Purchasing Agent shall undertake a
thorough review of known products and a comparison of features which would most closely mcct the
city's needs at the least cost;"
HJW has established the digital terrain model (DTM), a largc data set for the area, and control registration
points from previous projects conducted for the participating agencies in 2001 and 2003. This work could
be re-established by other providers, but at significant additional expense.
In 2001, the City of Livermore, the City of Pleasant on, and Zone 7 issued a request for bids to obtain
aerial imagery as ajoint purchase. In rcsponse to this request, three bids were received. Based on those
agencies' reviews of the bids, it was determined that HJW was the most qualified, and it was
recommended to utilize HJW as the firm to conduct the work.
HJW was approached by the City of Livermore in February 2003 to develop a new scope of work for the
2001 aerial photography area. Other than the flight area, the services and parameters required for the
proposed 2003 aerial orthophotography project matched those ofthe 2001 project. HJW was stin highly
qualified to do the work and their pricing structure was stin competitive. HJW again conducted the work
in 2003 and this time the City of Dublin participated with the other agencies.
At this time the City of Livermore has again determined that HJW is the most qualified to again do the
work and offers the most cost-effective solution for the participating agencies. An aerial photography
update for the City of Dublin win show changes due to development over the past two years. The HJW
product of 2005 wilJ also be of a much higher resolution than the previous 2003 imagery.
RECOMMENDATION: Staff recommends that the City Council waive the competitive bid
process pursuant to Dublin Municipal Code §2.36.050(a)(6) and adopt resolution approving the
Memorandum of Agreement with the City of Livermore, City of Pleasant on, and Alameda County Flood
Control & Water Conservation District Zone 7 regarding sharing the costs for services provided by HJW
in the amount of$53,199.44, and adopt resolution approving an Agreement For Consulting Services
between the City of Dublin, City of Livermore, City of Pleasanton, Alameda County Flood Control &
Water Conservation District Zone 7, and HJW Geospatial, Inc. for aerial orthophotography services.

2005 Livermore Valley Mapping and Orthophotography
Project Scope
HJW will extend the relationship that has developed over the last 4 years by undertaking
a project to update the mapping and orthophotographic coverage we have provided to
the Livermore Valley Partners. The project will have two components: an area of high
resolution orthophotos meeting 100-scale accuracy specifications with contours
generated on a two-foot interval and an area of lower resolution orthophotos meeting
200-scale accuracy specifications with contours generated on a 10-foot interval. The two
project components are referred to as the HighRes and LowRes areas in the attached
Specifications and their extents are shown in Exhibit C following.
Photography and Control Methods
The new photographic materials that will be used in this update project will be consistent
with the materials used in the previous projects.
The HighRes area will be photographed at 1 :7200 in color and controlled by a
combination of Airborne GPS data collected at the time of flight, ground control
points from our previous work, and newly set and surveyed ground points. The
project pians call for approximately 500 exposures in 35 flight lines supported by
40 ground points.
The LowRes area will be photographed at 1 :24000 in color and controlled by a
combination of Airborne GPS data collected at the time of flight, ground control
points from our previous work, and newly set and surveyed ground points. The
project plans call for approximately 40 exposures in 4 flight lines supported by 8
ground points and ties to older photography.
Contour Mapping
The controlled photography will be used to update and extend the terrain model that was
developed in 2001 and revised partially in 2003. The terrain data generated for the City
of Dublin in1995 will also be incorporated and revised. The method relies on using our
softcopy compilation instruments. In the softcopy environment old data is viewed as it
overlays new stereo imagery enabling the compiler to easily identify areas of change.
The old data is clipped out and new data is compiled to accurately represent the
changed conditions. Contours are then generated as normally and introduced into the
stereo view to check for fidelity to the ground configuration. The contouring and spot
elevations are converted to AutoCAD .DWG format and cut into the tiling scheme of
each partner.
Digital Orthophotography
The new photography will be scanned at a resolution of 2000 dpi and subjected to
radiometric color balancing before ortho-rectification. The camera locations and
orientations from the aerotriangulation adjustment and the revised terrain model will be
z: \(.~\b~1 "e.~'
I <t iIQ 2.. z.-
used to generate an ortho-rectified image for each exposure. These orthophotos will be
mosaicked using seamline techniques designed to eliminate building lean conflicts from
the final orthophoto tiles. Special nadir exposures will be made of major elevated road
structures to eliminate the patches of missing ground imagery that would othelWise
result when elevated overpasses are shifted into their corrected location. The delivery
tiling scheme of the orthophotos will be as specified by each partner. Uncompressed
.tif/tfw and MrSID compressed .sid/sdw format images in both color and black/white will
be provided on DVD.
