Osceola County Board of County Commissioners Meeting

December 4, 2006


Location

Location


Narcoossee road

Narcoossee Road

  • Corridor Study from US-192 to Orange County line (~7.4 miles)

  • Primary north-south arterial road in Northeast County


Existing conditions

Existing Conditions

  • 2 lane rural arterial road

  • 12 – foot travel lanes

  • 4 – foot shoulders

  • Open drainage system

  • 55 MPH speed limit


Need for improvement

Need for Improvement

  • Current Average Annual Daily Trips (AADT) = 15,002 – 16,247

  • Projected to fail adopted Level of Service (LOS) ‘D’ in 2010

  • By 2030, projected 44,000 – 47,500 AADT


Need for improvement1

Need for Improvement

  • Safety

    • 2005: 21 accidents (7 injuries)

    • January 2006 – March 2006: 9 accidents (10 injuries)


Typical sections

Typical Sections

  • Urban section

  • Closed drainage

  • Design for 6-lane

  • Construct 4-lane

  • 45 MPH design speed

Methodology roadway

Methodology - Roadway

  • Typical section requires 130’ of R/W

  • Minimize R/W takes

    • Existing R/W Typically 100’

    • Many segments of 130’ R/W

  • Minimize impacts to existing buildings

  • Minimize environmental impacts


Cyril s dr to orange county line

Cyril’s Dr. to Orange County Line

Existing Conditions:

  • Single family residential on both sides

  • Houses on left are closer to road

  • Reduced typical section

    Preliminary Recommendation:

  • Right widening

  • 15’ additional R/W required


Orange county line to boggy creek rd

Orange County Line to Boggy Creek Rd.

  • Inter-local agreement

  • Maintain reduced typical section

  • Orange County is constructing 6-lanes

  • Possibly re-align Boggy Creek Rd. intersection
