Objective:
Complete design of alternate sewer route in Arabian Avenue in lieu of the Baxter
Meadows HOA sewer route and shift sewer alignment east of the Maynard Border Ditch
through the City Park from Baxter Lane to Equestrian Lane. Also includes miscellaneous
design revisions not included in the original scope of work.
Subtasks:
412 Misc. Final Design Revisions (Fiber,Nelson Sub, GW Plume)
Revise final plans to include items not in the original project scope of work,
including: adding fiber optic conduit and associated appurtenances at the I-90
crossing and forcemain route; update plans to include connections to the water
main and sewer forcemain for the Nelson Meadows Subdivision; address
groundwater dewatering associated with the solvent plume; and prepare
deviations and coordinate with DEQ on permitting to include the water and sewer
main in a single casing at the I-90 crossing and setbacks from wells along the
project corridor.
413 Review As-builts and Existing Information for Arabian Route.
The existing as-built drawings for the Arabian Avenue sewer route include the
Baxter Meadows Subdivision Phase 3 record drawings from 2007. These record
drawings will be reviewed with respect to the existing sewer and water main
depth in Equestrian Lane, Arabian Avenue, Kimberwicke Street, and the existing
water and sewer service locations in Arabian Avenue. Other existing information
includes private utility maps, aerial imagery, and the City of Bozeman GIS
mapping.

1 of 3
done to update the existing base drawing sheets and show the existing lots along
Arabian Avenue. The topographic survey limits will be an average of 60 feet
wide and extend from the original Norton sewer route located on the south side of
Equestrian Lane on the west side of the Maynard Border Ditch, then northeast to
the intersection of Equestrian Lane and Arabian Avenue, then north in Arabian
Avenue to the north side of Kimberwicke Street, and then west approximately 100
feet to the original Norton sewer route. Additional survey will also be completed
for the revised route through the City Park on the east side of the Maynard Border
Ditch from Baxter Lane to Equestrian Lane. Utility locates will be requested for
the Arabian route and survey measure downs will be conducted on existing water
valves and sewer manholes along the Arabian route. The existing survey base
map will be updated based on the additional topographic survey.

Design sewer alignment and depth in Arabian Avenue based on following the
existing sewer alignment in Arabian Avenue at a depth necessary to reconnect the
existing sewer services into the new 27-inch sewer main and cross under the
existing water services. It is assumed that the revised sewer main route will
connect back into the original Norton sewer design at Baxter Lane and north of
Kimberwicke Street without redesigning the sewer main upstream or downstream
