Question 1

Slope guidelines for development

Answer 1

The following contains some general slope guidelines for urban development:

0-0.5% = no drainage, not suited for development;
0.5-1% = no problems, ideal for all types of development;
1-3% = slight problems for large commercial areas; acceptable for residential;
3-5% = major problems for commercial/industrial/large scale residential;
5-10% = suitable only for specially designed development.

Question 2

Floor Area Ratio

Answer 2

Floor area ratio (FAR) is the ratio of the gross floor area of a building to its ground area. It is used primarily to determine building density on a site; i.e., the size of a building in relation to the size of the lot where it sits.
