Nivaar worked solution (AI-drafted; not reviewed by a licensed engineer)
National Exams, May 2013 — 04-Geom-B6, Land Use, Planning & Environmental Management. Three hours; closed book (approved Sharp/Casio calculators permitted). Format: seven questions of equal value (20 marks each); the paper directs that answering any five (5) of the seven constitutes a complete exam (100%), and the first five as they appear in the answer book are marked. All seven questions are solved in full below so the set serves as a complete study resource. Content is framed in the Canadian planning context (the Canadian Institute of Planners definition of planning; provincial planning legislation and official community plans; Canadian metropolitan and small-town examples), consistent with the Engineers Canada / EGBC syllabus for this exam.

Small towns differ from large cities not merely in size but in the character and pattern of their land uses. Their development reflects a simple economic base, a modest population, and an origin closely tied to the original survey and to a single transportation spine.
A single “Main Street” core. The commercial heart of a small town is typically a linear main-street strip rather than a clustered downtown — shops and services line one principal road, usually the through-highway or the street facing the railway station, with civic and institutional buildings (town hall, churches, arena, post office) close by.
Low density and a dominant single land use. Residential areas are overwhelmingly low-density single-detached housing on generous lots. Densities are low, journeys to work are short, and the town is compact enough to be walkable, though car-oriented.
Mixed, weakly segregated uses. Land uses are far less specialised and less rigidly separated than in a city. Small workshops, stores and homes coexist, and formal zoning — where it exists at all — is simple. Industry, if present, clusters near the rail line, highway or the resource it depends on.
A grid tied to the survey and the transport spine. The street pattern is usually a rectangular grid derived from the original townsite survey, oriented to the railway or highway that gave the town its start. That spine still organises the town’s land uses.
A central-place service role. Many small towns exist as service centres for a surrounding rural hinterland (central-place function), so their commercial land supports agricultural services, machinery, and retail drawing on the countryside.
Vulnerability and change in the pattern. The land-use pattern is sensitive to two forces. A narrow economic base — the single-industry resource town — makes the whole settlement vulnerable to one employer. And the highway bypass or edge-of-town big-box/strip development draws commerce away from Main Street, hollowing the historic core and producing ribbon commercial development along the approach roads — a central challenge for small-town planning in Canada.
