SCOPE OF SERVICES

2.1 BACKGROUND:

Dirksen Drive (CR 4162) is a 2-lane undivided Urban Minor Arterial with open swale drainage that extends east-west from US 17/92 to Sunrise Boulevard within the City of DeBary in Volusia County, Florida. The land-use on both sides of Dirksen Drive is a mix of residential, commercial, and parkland (Gemini Springs Park) with dedicated left turn lanes provided at US 17/92, Gemini Springs State Park, Mansion Boulevard, River Village Drive, and Palm Road. Portions of the existing roadway contain superelevated horizontal curves and sight distance within the project limits is generally adequate. The posted speed limit along this corridor is 45mph between US 17/92 and Palm Road. Between Palm Road and Sunrise Boulevard, the posted speed limit reduces to 35mph. The north side of Dirksen Drive lacks sidewalk up until approximately 160 feet west of Sunrise Boulevard. A shared-use path runs adjacent to the south side of Dirksen Drive from Mansion Boulevard to Sunrise Boulevard. At Mansion Boulevard, the Springs-to-Springs Trail crosses Dirksen Drive. There is a marked crosswalk and a Trail Wayfinding sign at this location.

Overhead utilities are found on the north side of the corridor. There is no street lighting on either side of Dirksen Road.

Currently, Dirksen Drive experiences heavy volumes especially when forced or unforced incidents occur on Interstate 4. The corridor is used as a detour by providing access from Interstate 4 to multiple north-south local city roads including State Road US 17/92. From past conversations with the City of DeBary, a primary concern was raised with cut-through traffic in nearby neighborhoods when Dirksen Drive becomes congested. City officials stated cut-through traffic occurs on almost every side street intersecting at Dirksen Drive within the project limits.

GENERAL SCOPE OF SERVICE:

To alleviate the substantial congestion on Dirksen Drive during periods of high congestion on Interstate 4, capacity improvements were recommended particularly the widening of Dirksen Drive to a 3-lane undivided typical section configuration. Widening to 3-lanes will accommodate extra traffic demand and provide some benefit during Interstate 4 incidents. Coordination with the City of DeBary and FDOT is expected. The County ROW Office will complete all services related to ROW acquisition including negotiations with existing private property owners. This project will consist of two phases – A Study Phase followed by a Design Phase.

Study Phase:

A more formal corridor evaluation with engineering concepts to better understand and define the implications of the improvements will be required. Design Consultant will revisit the current Dirksen Drive Evaluation Study prepared by TEDS on September 24, 2020 and review Alternative No. 3 – Three-Lane Undivided Typical Section with Preliminary Concept Plans, enclosed as Exhibit A. The Study Phase of this project will include updating traffic counts, addressing safety concerns at the crossing of the County Trail at Mansion Boulevard, and conducting preliminary engineering analysis to determine how best to implement the 3-Lane Alternative. The proposed widening improvements to be considered in the preliminary engineering analysis will require coordination with the City of DeBary and FDOT. Additional coordination with County Traffic Engineering and FDOT Traffic Operations for signal timing and queueing concerns at the intersection of US 17/92 and Dirksen Drive is recommended. The preliminary engineering analysis will include preparation of updated concept plans and cost estimate with a narrative report.

Key Attributes from Alternative No. 3 include:

1. An Urban Typical Section (curb and gutter)

2. 11-foot travel lanes (one for each direction)

3. 12-foot two-way continuous left-turn center lane

4. 6’ sidewalk at the back side of proposed curb on the north side of Dirksen Drive as permitted by right-of-way constraints. (No sidewalk was considered on the south side of the corridor due to right-of-way constraints and the availability of the existing shared-use path (trail) on the south side of Dirksen Drive).

5. Piping drainage swale on the north side of Dirksen Drive may be required.

6. Includes a minimum right-of-way width of 56 feet. Additional easements outside of the right-of-way will be required to tie-down from the roadway to existing ground.

7. From the US 17/92 intersection heading east along Dirksen Drive, Alternative 3 extends both the existing dedicated right turn lane an additional 300 feet (approx.) and the existing dedicated inside left turn lane an additional 400 feet (approx.) to increase lane capacity, reduce queue lengths, and facilitate better turning movements.

8. Alignment shifts, cross slope corrections, and/or superelevation adjustments may be required to accommodate the proposed widening.

The following professional services will be required for the Study Phase:

• Full Topographic, Boundary, and LIDAR Survey Services

• Full Level B Utility Investigation (SUE – Horizontal & Vertical Locates)

• Full ROW Mapping Services – County may pursue Advance ROW Acquisition during Study

Phase

• Traffic Engineering, Qualitative Assessment, and Operational Modeling Analysis Services

• Preliminary Utility Coordination Services

• Volusia County, City of DeBary, and FDOT Engagement/Coordination
