John Stevens, Chief of Capital Services
Brian Kagarise, P.E., Project Manager
Slide 2
▪ Billingsley Road is an existing 2 lane rural roadway,
primarily consisting of 20 to 22 feet of paved width and
no shoulders throughout the majority of the study
limits.
▪ For the majority of the corridor, the County claims
prescriptive easements along the corridor that cover
30 feet of width centered on the paved roadway.
Background
Slide 3
Background
A study to identify areas of safety concerns/issues along
the entire corridor was completed in April of 2016. The
study examined the following:
▪ Geometric Criteria
▪ Crash Analysis
▪ Road Safety Audit
▪ Recommendations
Slide 4
Recommendations
The list of recommended safety improvements, in order
of relative importance identified were:
1. Prince Edward Drive Intersection improvements
2. Restoration of surface friction between Middletown
Road and Spring Valley Road
3. Selective tree removal to create a minimum of 8’
clearance from edge of pavement
4. Restoration of surface friction between MD 229 and
Prince Edward Drive
5. Geometric improvements between Pearl Street and
Prince Edward Drive improvements

Slide 10
Issues/Concerns (Initial Submission – 6/2016)
▪ Substandard design to minimize impacts to properties:
• Right-of-Way width 60’ in lieu of 80’
• Shoulders 2’ in lieu of 8’
• Lacking deceleration lane at Pearl St.
• Historical property impacts
▪ During meeting with County staff, owners expressed
objections for properties with major impacts
• House within 25 feet of proposed roadway
• Close proximity of two wells
• Driveway access cannot conform to ordinance
• Impact to septic system drain field

Recommendations Prince Edward Drive & Pearl Street Improvements (1,5)
Slide 12
SWM & Alignment 1st Intermediate Design (10/2017)
▪ Adjusted road alignment to:
• Minimize impact to property on north side of road
• Relocate SWM facility to minimize impact of grading along
frontage of property
Recommendations Prince Edward Drive & Pearl Street Improvements (1,5)

SWM & Alignment 2nd Intermediate Design (9/2019)
Recommendations Prince Edward Drive & Pearl Street Improvements (1,5)
Slide 14
SWM & Alignment 2nd Intermediate Design (9/2019)
▪ Road alignment revised to meet current road ordinance:
• Right-of-Way width reflects 80’
• Revise road shoulders to 8’
• Include acceleration/deceleration lane at Pearl St.
• Compliance with Road Ordinance/AASHTO vertical
alignment requirements
• Improved horizontal alignment to remove reverse curve
• Extended project limits to address sight distance
Recommendations Prince Edward Drive & Pearl Street Improvements (1,5)

SWM & Alignment 2nd Design Submission (12/2019)
Recommendations Prince Edward Drive & Pearl Street Improvements (1,5)
Slide 16
SWM & Alignment 2nd Design Submission (12/2019)
▪ Road alignment to finalize 2nd Intermediate SWM & Alignment
design
▪ Reviewed and Approved by Codes Permits and Inspections
Services on 1/27/2020
▪ Resubmission forthcoming to adjust alignment to:
• Show complete property acquisitions to avoid impacts to some properties
on south side of road
Impact to septic drain field
Impact to private well
Negates need for retaining wall
• Provide property for partial on-site mitigation to meet forest conservation
requirements
