Indian School Road,
Drinkwater Boulevard to Pima Road, Drainage
Improvements
Scottsdale,
Arizona
Dibble is currently
providing drainage design services to the
City of Scottsdale for 2 miles of Indian School
Road between Drinkwater Boulevard and Pima
Road. Currently, the corridor regularly experiences
mild flooding due to pavement drainage and
an undersized catch basin and storm drain
system. As part of roadway pavement improvements,
Dibble is updating the existing drainage measures
along the corridor to accommodate runoff from
a 10-year design storm event. The project
includes a new hydrologic analysis of both
onsite and offsite urban watersheds in order
to provide a comprehensive drainage solution.
Proposed improvements to the corridor include
catch basin upsizing and relocation, improved
pavement grades, and a new 72-inch storm pipe
to supplement the existing storm drain system.
