Feasibility Assessment UpdateProcess• Refinement of alternatives through collaboration between RDA, 

TJPDC staff, and stakeholders

• Stakeholder input solicited via e‐mail and online survey forms

• Concept drawings and Feasibility Analysis update to reflect the refined alternatives

Alternative A‐1

Free Bridge Overpass/Expressway

The original Alternative A was split into A‐1 and A‐2.  Alternative A‐1 only includes construction of an elevated structure that would route two lanes of US 250 east and west bound traffic over the intersections of US 250/20 and US 250/High Street. The existing intersections and bridge will remain below the flyover structure.

Alternative A‐2

Jug Handle/ Left turn elimination at US250 W and High Street

Alternative A‐2 includes reconfiguring the US 250 and High Street intersection to eliminate left turn movements from west bound US 250. In this configuration traffic wanting to make a left turn would pass through the intersection and make a right at Landonia Circle.  A new connector road would then join Landonia Circle to River Road where a traffic light would be installed.

Alternative B

Park and Ride, and Bike/Pedestrian Connections

This alternative includes a new park and ride lot located at the VDOT offices (VDOT way and Richmond Road) and a hard surface trail. The trail will run parallel to the Rivanna River and then cross the river on a new bike and pedestrian bridge in the vicinity of Riverview Park. The trail will provide the opportunity for making connections further downstream along the river.

Alternative D‐1 & D‐2

Rivanna River Parkway

Alternative D‐1 includes construction of a new road linking Route 20 with Rio Road. This new road would have two vehicle travel lanes with two bike lanes (similar to the John Warner Parkway). The intersection with Route 20 would be aligned with an extension of Olympia Drive. In addition to adding a new 2 lane connection from Route 20 to Rio Road the project would also include widening Rio Road to 4 lanes from Pen Park Lane to the John Warner Parkway intersection.Alternative D‐2 is the same as D‐1 but considers improving Elk Drive through Darden Towe Park rather than constructing a road west of the Elks Lodge and the slated development for the land parcel south of the Lodge.

Alternative F

Increased Lane Capacity on Free Bridge

This alternative increases the number of through traffic lanes between High Street and Route 20 to three lanes in each direction. Increasing the number of lanes requires removal of existing sidewalks on Free Bridge and relocating them to a dedicated bike and pedestrian crossing immediately down river of the existing span.

Alternative G

South Pantops Drive Connector Bridge

This alternative includes a new bridge connection between New House Drive/South Pantops Drive and East High Street. The bridge would be a two lane urban style bridge with appropriate bike and pedestrian facility accommodations. Additional considerations include a new intersection at High Street aligned with Willow Drive, a new intersection at New House Drive/South Pantops Drive, and improvements to South Pantops Drive through the shopping center.

Alternative I

Intersection Improvements at US 250/Route 20 & High Street

This alternative consists of intersection improvements that would improve side street turning movements in addition to a west bound right turn lane from US 250 to Route 20. Additional side street lanes would be added to allow the implementation of split phase light timing. These changes have the potential to reduce collisions and improve intersection efficiency.

Estimates

Preliminary Engineering

• Estimated as a percentage of the Construction Cost using a sliding scale from 20% for a $5 million project to 10% for a $400 million project

Estimates

Right of Way and Utilities

• RDA Right of Way Staff researched assessed real estate values to develop a price per square foot cost

• The square feet of right of way required was measured off of the concept drawings based on GIS information

• A multiplier of 2.75 was used to account for temporary easements, permanent easements, damages, and administrative costs.

• Individual cost assessment was performed for parcels requiring relocation/total take.

• RDA Utility Staff used the VDOT Project Cost Estimating System (PCES) to estimate utility relocation costs based on field reconnaissance and utility records research

Estimates

Construction

• RDA Engineering Staff determined whether VDOT’s PCES tool or performing a quantity take‐off was the most appropriate method for each alternative

• PCES is a parametric estimating tool developed by VDOT that estimates construction cost using historical price data based on certain project characteristics and measurement inputs.  It’s best suited for typical roadway widening projects or new roadway construction

• On projects not deemed suitable for PCES, RDA staff calculated quantities of major construction items and used unit prices from VDOT Construction Division’s District Wide Averages published online.  Percentages for incidentals (smaller items not able to be quantified with this level of design) and contingencies were added to arrive at a final construction estimate

Next Steps

1. TJPDC Staff will begin the process of running alternatives through the Regional Ecological Framework tool and Travel Demand model

2. Results of this process will be discussed at the next meeting in September

3. Stakeholders can expect information about how alternatives would impact the natural environment and regional traffic conditions

4. Final Report to be completed October 31, 2014
