Percent slope is computed as:
This is the standard civil engineering definition of grade/slope used in surveying, drainage, and roadway work. With a 10 m × 10 m grid, the plan distance between two grid points is determined from the grid spacing (10 m increments). Using the elevations/contours shown at pointsD1andC2, the elevation difference divided by the plan distance yields a slope that matches6.79%. This corresponds to a rise/fall of roughly0.679 m per
10 mof horizontal distance (or an equivalent ratio based on the exact D1-C2 spacing in the grid), which is consistent with the computed percent. Therefore, the correct selection is6.79% (Option C).

Before asphalt paving, the immediate supporting layer must be at the correct line and grade because asphalt thickness is builton top of the prepared base. Thetop of baseelevation controls final pavement structure thickness and the finished riding surface elevation when combined with asphalt lift thicknesses. If base grade is too high or low, the asphalt thickness will vary outside tolerance, which can affect performance (rutting, cracking), drainage crossfall, and tie-ins at structures and curbs. Standard field inspection practice therefore verifies base course elevations (and crossfall) immediately before paving so corrections (regrading
/recompaction) can be made while accessible. This fits typical roadway QA/QC sequencing: shape and compact subgrade/base to the specified elevations, confirm, then place asphalt lifts to achieve final grade.
Hence, the elevation that must be confirmed prior to placing asphalt istop of base.

Increasing slump from80 mm to 200 mmis a large jump in workability. Adding water would increase slump but typically raises the water-cement ratio, which can reduce strength and durability and increase cracking risk unless it remains within permitted limits and is authorized. Industry guidance on jobsite water addition recommends consideringwater-reducing admixtures / superplasticizersas the preferred alternative for increasing slump while maintaining concrete performance, provided segregation is avoided and proper mixing is performed.
Ahigh-range water reducer (HRWR), also called asuperplasticizer, is specifically intended to produce a major increase in slump/flow at essentially the same water content, achieving very high workability concrete for placement. Low-range water reducers typically do not provide such a large slump increase. Therefore, the correct action is toadd a high-range water reducerto achieve the required 200 mm slump without compromising the designed water-cement ratio and associated properties.

The bylaw excerpt establishes mandatory requirements (one family, minimum 120 m² floor area, and minimum setbacks) and then provides the required administrative action in Section 3.4:any application that does not fulfill the above requirements shall be referred to Council. The correct decision is therefore governed directly by the regulatory text: when any requirement is not met, the prescribed next step is referral rather than approval. Option C matches the bylaw's stated process exactly by directing the application to Council due to noncompliance. Options B and D propose outright rejection reasons that the excerpt does not authorize as the required action; the excerpt explicitly states "referred to Council" for noncompliant applications. Option A is only valid when all requirements are met. Accordingly, the correct response isrefer to Council.

Survey work depends on traceable, reproducible observations. Handwritten field notes (field book entries, sketches, stationing, and benchmark ties) function as theprimary recordof what was measured, under what conditions, and how control was established. Lindeburg describes that elevations of temporary benchmarks are generally found infield notesand local official filings, reflecting that field notes are treated as an enduring record used later for computations, verification, and re-establishment of control. This is why good surveying practice emphasizes complete notes, clear sketches, and unambiguous identification of points-so results can be checked, recalculated, and defended long after the crew leaves site. While survey data supports mapping and may indirectly support disputes, the fundamental purpose of handwritten notes is to create apermanent, auditable recordof survey results and control ties.
