NW 8th Avenue Reconstruction + Creek Sediment Control

The resurfacing and reconstruction of NW 8th Avenue was divided into three sections.

Sections A and C included removing and pouring selected sections of sidewalk, f-curbs, and driveways; installing a new pedestrian crosswalk with Pedestrian Activated Rapid Flashing Beacons; milling the roadway to various thicknesses; and applying new asphalt with new asphalt striping. The new plan altered the existing striping pattern to remove some of the existing on-street parking to allow for dedicated bike lanes traveling in both directions.

Section B consisted of removing all five-foot sidewalks and replacing with new ten-foot sidewalks, installing new concrete medians within the roadway at two locations, reconstructing ADA ramps; and creating new paver medians with ADA ramp truncated pavers. The project also included widening approximately 600 linear feet to install a new turn lane at NW 31st Drive and a new pedestrian refuge median and crosswalk. The three new pedestrian crosswalks feature Pedestrian Activated Rapid Flashing Beacons. Four new 24 inch RCP culvert crossings with a new stormwater structure were set and modified to tie into existing stormwater pipes, which will need to be modified for the roadway widening. Downstream at Possum Creek, the project also includes stabilization and creek repair by using new steel sheet piling and concrete to stabilize the creek bank and bottom around the roadway culvert. Downstream of Hogtown Creek, the creek bed was excavated down to 84 feet and stabilized.

From NW 8th Avenue, Hogtown Creek was dredged to Elizabeth Creek so that Hogtown may flow into Elizabeth. The roadway was milled to 5 inches deep with new asphalt and lane striping. NW 8th Avenue required extensive coordination with adjoining neighborhoodstakeholders, utility coordination, and specialized phasing. We worked in non-peak hours to limit disruption to local school and park schedules. During design development, we met with the City of Gainesville Public Works, GRU, GRUcom to identify any potentially clashing utilities with the new stormwater piping. We also met with the St. Johns River Water Management District, DEP, and the City of Gainesville Parks, Recreation, and Cultural Affairs to develop a plan to install cross culverts that hydrate the downstream wetlands and work within the wetland limits to remove sediment on the Hogtown Creek downstream.
