QUESTIONS AND CORRECT ANSWERS WITH
COMPLETE SOLUTION
1. If a new residential development is planned near a transient water supply well, and the
setback distance required is 20 feet, what would be the implications if the
development is constructed only 15 feet away from the well?
There would be no implications as the distance is acceptable.
The development would likely face legal challenges due to non-compliance.
The water supply would be improved due to the proximity.
The construction would enhance the well's water quality.
2. A permit is required for a prefabricated above-ground swimming pool, accessory to a
Group R-3 occupancy, that is a minimum of _____ in depth or has a capacity of
more than __ _.
18 inches; 4,000 gallons
24 inches; 5,000 gallons
30 inches; 5,000 gallons
36 inches; 6,000 gallons
3. Explain why maintaining a setback distance of 100 feet for water supply wells is
important for environmental protection.
It prevents the depletion of groundwater resources.
It reduces the risk of contamination from nearby sources.
It allows for easier access to water supply for communities.
It ensures that water supply wells are visible from a distance.
4. A public water main shall be deemed available to a building, other than a one or two
family dwelling, if a property line of such building is within ' measured along a
street, alley, or right of way, of the public water supply system.

feet and a slope of 40%, what would be the appropriate setback distance to ensure
compliance with safety regulations?
10 feet
15 feet
20 feet
25 feet
7. Explain why maintaining a setback distance from surface waters is crucial for water
supply safety and environmental protection.
It prevents flooding in urban areas.
It reduces the risk of contamination from pollutants.
It ensures adequate space for recreational activities.
It allows for the construction of additional structures.
8. What is the required setback distance from the mean high-water mark for tidal
influenced waters such as marshes and coastal waters?
25 feet
50 feet
75 feet
100 feet
9. Slopes
