3.0 Subdivision Design Flashcards
What is subdivision?
Subdivision is the process of dividing existing parcel(s) into new parcels, or changing existing property boundaries. The common sub-division process is to create multiple single-family lots from a single-parent lot. The property owner or developer will apply to the host municipality to complete a subdivision process.
Subdivision is the process of altering legal property boundaries. Most often this involves the division of a larger property into smaller lots and may include the realignment of an existing property.
Where can the Legislation regulating the subdivision process be found?
In the Local Government Act, and the Land Title Act of British Columbia. In the New Westminster subdivision and Development Control Bylaw no. 7142, 2007 requires that all subdivisions be approved by the municipality’s Approving Officer. The Director of Engineering has been appointed by the council as the City’s Approving Officer.
Types of Subdivision
Adjusting or realigning an existing property line
Creating several lots from one or more existing properties
Creating several strata lots from one or more existing properties
Creating several lots from an existing property with the creation of a road
Types of setbacks for Residential Subdivisions
Setbacks: Front setback, rear setback, street side yard
The subdivision process ensures that:
New lots are adequately serviced with water, sewers, underground electrical, telephone, street lighting, roads, sidewalks, street trees, and other requirements identified by the City.
The subdivision meets the minimum lot size and frontage requirements under the Zoning Bylaw
Future development opportunities are not obstructed (supports future development of neighbouring opportunities)
The subdivision is consistent with the requirements of the Offical Community Plan
Subdivision features
Basic Road Pattern
Access Considerations
Servicing Considerations
Residential Lot standards
Urban rezoning and Subdivion process
Urban and rural Conditions
Parkland Dedication
Lot Layout Efficiency
Primary objective: max. Lot yield to suit market condition
Grid street pattern (major transportation corridors)
Curvilinear pattern (local streets)
Grid street pattern is most efficient lot subdivision
Cul-de-sac pattern attracts certain buyers (families)
Accurate survey by BCLs
Saleable frontage ratio (ideal revenue to street length= 2:1)

Building envelope
Defined portion of a lot where building construction will be permitted, or other activities as described on the plan. Building envelopes are placed on certain lots and plats for a reason, such as to protect the natural terrain, drainage, riparian areas, and vegetation
