Project Description

Clients: Collier County and Lee County

Collier County officials selected Hole Montes to provide design, engineering, surveying, permitting and project management services for the portion of Livingston Road from the Lee County line south to Immokalee Road. The Hole Montes team conducted design and alternate location studies to arrive at an alignment that would reduce environmental and right-of-way impacts to existing wetlands and adjacent parcels. Design plans were prepared for 6.1 miles of 16-inch and 12-inch water mains, traffic signalization, signs and pavement marking, lighting and right-of-way plans for two lanes of an ultimate six-lane roadway including a bridge structure over the Cocohatchee Canal.

Required permit applications were coordinated with the FDEP, U.S. COE, SFWMD and the Big Cypress Basin.

Lee County then selected HM to design the four-laning of Imperial Street in Bonita Springs from the Collier County line to Bonita Beach Road, then in a second phase, northward to East Terry Street. These two segments of Imperial Street both dead-end at the Imperial River. A new four-lane bridge spans 325’ across the Imperial River and its floodplain to complete the Livingston Road/Imperial Street/Three Oaks Parkway connection from Collier to Lee Counties. The roadway design incorporates an urban cross-section with concrete walks, bicycle lanes, and landscape buffer areas. Other services included corridor planning, development and evaluation a new floodplain model for the Imperial River, and cooperative corridor drainage planning.
