Dear Mr. Sauceda:
Halff Associates presents this Amendment No. 3 for additional services to City Project
No. 01499. Amendment No. 3 shall include the effort necessary to complete the plans
and project technical specifications for the Walsh Ranch Sanitary Sewer Extension
Phase 2. The plans will be constructed by the developer's contractor so no bidding
documents or services are required. Halff completed the original design of the
approximately 4,700 linear feet of 24-inch diameter sanitary sewer extension in
September 2004. Following is the scope and fee for completing the construction
documents.
SURVEY
Horizontal and Vertical Control—Halff's sub-consultant, Gorrondona &Associates, Inc.
will verify and re-establish the horizontal and vertical control along the proposed
Phase 2 alignment, which is approximately 4,700 linear feet. Vertical and horizontal
control shall be verified /established from the GPS control points that TranSystems
established for the Walsh Ranch Projects.
Topographic Survey— Gorrondona will provide a topographic survey for the new
features along the route. The survey will locate all new features within the
topographic limits including but not limited to power poles, trees or tree lines,
buildings, sanitary sewer cleanouts, paving, fences, driveways, culverts, water
valves, sanitary sewer manholes, and grade breaks. Since the plans were
completed in 2004, the downstream manhole was constructed, a new driveway and
creek crossing was constructed off of Old Weatherford Road at approximately SS
Station 33+00, and a new fence was constructed on the north side of Old
Weatherford Road between SS Stations 40+00 and the 47+00. Halff personnel will

velocities and potential scour at the aerial crossings based on the latest hydraulic
models of Mary's Creek. Halff will update the aerial crossing plans to include any
additional general notes, sections, details and specifications to meet the latest
design standards and channel velocities. Halff will also make any modifications
necessary to accommodate a 30-inch sewer line.
