Site Evaluation & Layout Flashcards

A site evaluation reveals that the proposed fence line crosses a neighbor's property by 6 inches due to an old survey error. What is the correct course of action?

Answer: Halt the layout and advise the customer to resolve the boundary issue before proceeding

Installing a fence on a neighbor's property creates legal liability; the boundary dispute must be resolved through proper channels before installation begins.

What is the main reason for identifying the soil bearing capacity during a site evaluation?

Answer: To size footings so they can support fence loads without settling

Soil bearing capacity determines how large the footing must be to distribute the fence load and prevent differential settlement or tipping.

When evaluating a corner lot for fence installation, which unique consideration applies compared to an interior lot?

Answer: Sight-line triangles at intersections may restrict fence height near the corner

Most municipalities require a clear sight-line triangle at street intersections to maintain driver visibility, limiting fence height within that zone regardless of general height limits.

A property owner has a deed restriction limiting fence height to 4 feet in the front yard. The local zoning code allows 6 feet. Which standard governs?

Answer: The deed restriction, because it is the more restrictive of the two requirements

When both a deed restriction and a zoning code apply, the more restrictive requirement controls; deed restrictions are private covenants that can be enforced by other property owners.

Which tool is specifically used to establish a level reference line along an uneven grade during fence layout?

Answer: A line level or water level stretched between batter boards

A line level or water level provides a horizontal datum along the string line, allowing accurate measurement of how much the grade drops or rises between posts.

During site evaluation for a wood privacy fence, you note that one post location falls in an area with heavy clay and poor drainage. What is the best mitigation strategy?

Answer: Install gravel backfill around the post footing to improve drainage

Gravel backfill around the footing improves drainage, reducing moisture retention that accelerates wood decay and causes frost heave.

What is the purpose of a 'pull-string' layout method in long fence runs?

Answer: To maintain a straight alignment between two end posts across the entire run

A taut pull-string stretched between end or corner posts acts as a straightness guide so that intermediate posts are set in perfect alignment.
