The intensity of land use should not be so great as to cause congestion of building or traffic or to preclude the amenities of good housing.

Greater than or equal to 45 feet or 5 stories in height | 25% |
17.14.050 Usable open space.

B. For all multiple-family and assisted living center uses of land, usable open space shall be provided as follows:
Residential Structure | Square Feet of Open Space Per: | |
