INNOVATION IN CADASTRE AND LAND DEVELOPMENT
A new fire station in the Sacramento, Calif., area provides medical aid, fire
suppression, hazardous materials response, and other emergency services
to the region. The $4.5 million structure required significant soil excavation,
drainage reconfiguration, and retaining walls to lower the building pad elevation.
Earthwork and grading minimized the visual impact of the 15,000-square-foot,
30-foot-high building while retaining as many trees as possible.
County requirements to limit peak stormwater discharge to predevelopment
conditions required the inclusion of a stormwater detention basin. CivilStorm
was used to analyze the detention pond, outlet structure, and storm drain
utilities. The stormwater management system includes sustainability features
such as grassy swales, infiltration areas, and a detention basin to reduce peak
flow impact on an adjacent creek and downstream residents.

Existing above and below ground utilities within the project limits required
relocation, and new underground utilities needed to be routed to avoid conflicts
with new and existing pipelines. KASL used InRoads to generate profiles and
resolve conflicts; 3D PDFs and Google Earth to create structural sections of
pavement and underground utilities; and a Google SketchUp building model
referenced from the architect. Digital terrain models were used to determine
earthwork quantities and create contouring.
Transoft Auto Turn was used to verify adequate sizing to accommodate the
turning radius and circulation patterns of large emergency vehicles assigned
to the three-bay drive-through fire station. This analysis resulted in a redesign
of the hardscape area to reduce the amount of driveway required behind
the station. It also validated a decision to reduce the size and amount of the
retaining wall that was originally planned for the site. This, combined with
the driveway reduction, resulted in an estimated $100,000 savings in
