5.0 Off-Site Servicing 2: Road, Street lighting, Utilities (dry), Landscaping

Question 1

Roadworks

Answer 1

Connectivity: Access versus Mobility
Geometric Grades
Cross sections
Sidewalks and Crossings
Turn-arounds and emergency access
Bicycle facilities

Question 2

Bicycle facilities

Answer 2

Protected bike lane/cycle track
Bike path and trails
Multi use path
Bike lanes/road shoulders (painted)
Shared lanes
Bi-directional paths can provide cyclists more direct routes in areas with large block lengths and intensive land use.
Intersections require special consideration
Undirectional paths are generally recommended on roadways
Spectrum of Bikeway implementation
tactical/demonstration
Rapid implementation
Traditional implementation

Question 3

Turn-arounds and emergency access

Answer 3

Firetrucks and waste collection vehicles
Min 6m wide ROW with min travel width of 4m
Cul-de-sac and hammerhead
Max length is 150m
Or else secondary access is required
Place bulb on high side of street
The desirable max. Is 4%

Question 4

Sidewalks and Crossings

Answer 4

Generally on both sides except residential low density, residential, cul-de-sac and industrial
Boulevard between curb and sidewalk is preferred over monolithic sidewalk-curb
Median and Curb extension provide
Improved pedestrian visibility
Reduced crossing distance
Center refuge area
Optimize street parking

Question 5

Cross sections

Answer 5

Common Right-Of-Way is 20m
Arterial is more than 24m
Collector is 20-24m
Local is 15-20m

Question 6

Geometric Grades

Answer 6

TAC
Align new road diagonally across the contours (compromise)
Provides usable lot areas
Maintain manageable road gradient
Reduces cut and fill requirements
Driveway slopes are more gradual
Align new road at right angle to contour lines
Likely exceeds max allowable road grade
Driveway slopes are more gradual but retaining wall may needed on high side
Retaining wall max height (visual)
Still need side lot access to rear lot
Align new road parallel to contour lines
Maintain minimal road gradient
Cut and fill balancing
Potential steep driveways
Deeper gravity to service low side of road
Steep grades for lots (front to back)
Side lot access may be limited

Question 7

Connectivity: Access versus Mobility

Answer 7

Road classification (Arterial, Collector Local)
Higher order - mobility
Lower order - access to property

Question 8

Street Lighting and Dry utilities

Answer 8

Street Lighting designed by a professional electrical engineer
Illumination level to be met for specific road classification
Hydro, Telus, Fortis Gas
Electrical Power and Telecommunication

Question 9

Electrical Power and Telecommunication

Answer 9

Coordination of undergrounding of overhead lines
Coordination of service connections

Question 10

what is a Landscaping problem

Answer 10

Sidewalk Heaving
Protection

Question 11

Landscaping Protection

Answer 11

Tree drip line area
Tree fencing
Duration of construction activity

Question 12

How to solve Sidewalk Heaving

Answer 12

Select appropriate tree species
Use of root barriers
Provide suffiecient soil volume for tree health
Surround application
Linear Application

Question 13

Challenges and Future Trends

Answer 13

Multimodal transportation
Technological changes
Climate change resilience and adaption
Competition for limited road space
