Investment Category-Focused Criteria

1. Define High Growth Area Need: Provide a narrative to explain how proposed project is needed to serve a high growth where project is located. (Please provide quantifiable data that demonstrates high growth in population, employment, commercial development or daily traffic.)

The number of households in Dayton and it's surrounding areas have been growing at a rate of almost 10% since 2018 and are projected to continue that growth rate. The added capacity of a relief route will help divert through traffic from the downtown area of Dayton. Additionally, traffics coming from Liberty toward Houston can divert around Dayton, saving time for commuters. This new facility helps improve LOS on the existing US 90 through downtown Dayton and reduces congestion caused by through traffic.

2. Is the proposed project recommended in a statewide, regional, or local plans?

No

3. Please provide proposed project description (detailed project scope).

Divided 4-lane new location access-controlled roadway from FM 1960 to US 90 south of the City of Dayton. Typical section is proposed as 4-12' travel lanes, 10' outside shoulders and 4' inside shoulders with a grassy median. Grade separation at UPRR crossings and interchanges at US 90, SH 146, and FM 1409.

3a. Does the project provide access to new planned land use development (residential or commercial), or connects existing discontinuous networks?

Yes

3a-i. If yes, explain.

Dayton Relief Route will provide a connection between FM 1960 to the west and US 90 heading east. Currently this connection passes through the city of Dayton and is discontinuous. Additionally, the Dayton Relief Route will provide connection to existing properties in a more direct manner as well as provide opportunity for greater growth by reducing truck traffic through Dayton and creating a thoroughfare on the south side of town where commercial development can occur.

3b. Does the project expand existing networks to alleviate anticipated congestions?

Yes

3b-i. If yes, explain.

Dayton Relief Route provides an alternate route around Dayton, redirecting the truck traffic that otherwise travels through the city heading east toward Liberty. This additional facility will relieve traffic along the existing US 90. It is a access-controlled facility, reducing conflict at intersections and the existing RRs and providing for more free-flow conditions.

3b-ii. What is the estimated Level of Service after the project is completed.

LOS B

4. Does the proposed project provide an alternative route to existing corridor (Road or commuter transit)?

Yes

4a. If yes, explain.

Dayton Relief Route provides an alternate route around Dayton, redirecting the truck traffic that otherwise travels through the city heading east toward Liberty. This additional facility will relieve traffic along the existing US 90. It is a access-controlled facility, reducing conflict at intersections and the existing RRs and providing for more free-flow conditions.

5. Is the proposed project located on a facility identified as a hurricane evacuation route in any regional or local plans?

No

5a. If no, is the proposed project located on a facility that functions as an alternative to an evacuation route?

Yes

5a-i. If yes, explain.

Other Investment Category Focused Criteria

1. Was the project scored under Regional Goods Movement Category?

Yes

2. Please provide a narrative explaining how the proposed project improves traffic operations. Within the narrative, please include if the proposed project includes construction of truck only lanes or managed truck only lanes, construction of an interchange, or intersection improvements.

Existing US 90 through the City of Dayton has an AADT of over 22,000 on an existing 4-lane facility with multiple signalized intersections. This facility experiences severe congestion during AM and PM Peak Hours. The proposed relief route bypasses downtown Dayton, reducing congestion by routing through traffic around downtown, allowing for trucks to travel more freely. Grade separations at major cross roads and the UPRR will be constructed. The relief route will add capacity to the overall east-west movement through the area.

3. Please provide a narrative explaining how the proposed project improves walking and biking conditions. Within the narrative, please explain if the proposed project scope includes construction of a new or improved existing bicycle and pedestrian infrastructure on a project facility or in the vicinity of the project.

The proposed relief route would reduce congestion and traffic volume on US 90 and thus should improve safety for bike/pedestrian users of that facility.

4. Please provide a narrative explaining how the proposed project improves traffic conditions for transit services (local, express, signature, or commuter).

The proposed relief route should help reduce the traffic volume on existing US 90 through Dayton. This should likewise reduce congestion and improve the level-of-service for all users of the existing roadway (including transit providers).

5. Please provide a narrative explaining how the proposed project will reduce inoperability for significant periods due to infrastructure damaged by a collision with vehicles such as trucks, ships, and barges.

This project creates an alternate route for US 90 in the event of damage to existing infrastructure through Dayton or if US 90 is partially or completely closed due to a vehicular accident. Also, by allowing through-vehicles to by-pass downtown Dayton, the resulting reduced congestion should provide emergency vehicles better access through Dayton.

6. Please provide a narrative explaining how the proposed project will improve state of good repair and extend the service life of the project facility.

By reducing traffic on existing US 90, the proposed project should help extend the service life of the US 90 pavement. The pavement section for the proposed relief route would be built to design standard based on the latest traffic data and the new roadway would have a service life of several decades with minimal maintenance needed.

Planning Factors Criteria

1. What is the existing fatality crash rate at the project location? Regional crash data is available online on the crash data viewer. H-GAC staff will provide assistance in calculating the crash rates upon request.

1.275

2. What is the existing serious injury crash rate at the project location? Regional crash data is available online on the crash data viewer. H-GAC staff will provide assistance in calculating the crash rates upon request.

1.912

3. Please provide a narrative explaining how the proposed project reduces expected fatality and serious injury crashes. Narrative must include specific improvements (work types) included in the project scope. Crash reduction factors associated with specific work types can be found in the safety benefits calculation template. H-GAC staff can provide assistance in gathering the crash reduction factors upon request.

The proposed relief route would remove conflict locations as it will have grade separations at RR and cross streets. It would reduce traffic volume along the existing corridor from through vehicles, including heavy truck traffic, again eliminating many potential conflicts.  The proposed relief route would be built to current design standards with 12' travel lanes and 10' outside shoulders,  and the proposed design should include edge line and centerline rumble strips

Resiliency

1. Please select the vulnerability to flooding score at the project location based on the Regional Resiliency tool. H-GAC staff can provide assistance with the regional resiliency tool upon request.

Low

2. Please select the criticality score at the project location based on the Regional Resiliency tool. H-GAC staff can provide assistance with the regional resiliency tool up on request.

Model.HighGrowthAreaNeedsQuestionnaire.Resiliency2

3. Please provide a narrative explaining how the proposed project reduces vulnerability to flooding. The narrative must include specific improvements such as drainage improvements that are included in the scope.

The relief route would reduce the vulnerability to flooding as it would be built to current hydrologic and hydraulic design standards.  It would be designed to meet or exceed ATLAS-14 drainage standards.  With the relief route being designed to potentially higher drainage standards than the existing roadway (US 90) the risk of interruption of traffic due to flooding should be minimized. The profile of this new location roadway would be set at a sufficient elevation to not be overtopped by the design flood and this route could be used as an alternative to US 90 if there were flooding on US 90.

3. Please provide a narrative explaining how the proposed project provides benefits to vulnerable populations. Benefits include safety improvements, construction of or improvements to ped/bike facilities, or improvements to transit stops.

By providing an alternate route around Dayton, the proposed project should reduce traffic congestion and help minimize travel delays on existing US 90 through Dayton. The reduced congestion on US 90 should improve connectivity to and from the numerous employment opportunities along this corridor in Dayton. The reduced traffic volume and congestion on US 90 should also improve safety for bike/pedestrian users of that facility and it should reduce trip time for transit users (area served by Brazos Transit).

4. Please provide a narrative explaining how the proposed project avoids or mitigates adverse effects to vulnerable populations. A list of adverse effects was provided in detailed criteria document.

The footprint of the proposed roadway improvements would be minimized to limit impacts to adjacent properties, thus reducing any possible displacements of persons, businesses, etc. Any sound walls that are identified prior/during the National Environmental Policy Act (NEPA) process will be constructed on this project. Construction of this relief route would lessen traffic on existing US 90 and would improve the level of service of US 90 (improving access to adjacent properties and improving connectivity along US 90).

Impacts on Natural and Cultural Resources

1. Please provide a narrative explaining how the proposed project avoids or mitigates impacts to natural (flood plains, wetlands) and cultural (historic and archeological sites) resources. H-GAC staff can provide assistance in identifying natural and cultural resources located within a quarter mile buffer of the project location.

Floodplains present in the project vicinity include the 100 year, 500 year, and a floodway. In addition, wetlands are present. During project development, wetland information is provided to the design team to determine where the project might impact Waters of the U.S. (WOUS). The design is adjusted if possible to avoid and minimize impacts to WOUS. Any unavoidable impacts are mitigated through USACE approved mitigation banks. With regard to the floodplains present, the project would be designed to have no negative impact to the floodplain and we would coordinate with the floodplain administrator concerning these.
