Development Standards—Design Requirements | Town Center
d. Covered Entry. All houses shall provide a covered entry with a minimum dimension of eight feet by six feet. Exceptions may be granted by the director for the use of regional housing styles that do not traditionally contain such entries. Porches up to 200 square feet may project into the front yard. See SDC 21.07.050Q. e. Windows on the Street. Transparent windows and/or doors are required on at least 15 percent of the facade (all vertical surfaces facing the street) as determined by the director.
f. Stormwater Management. All developments shall adhere to sub-basin plans per SDC 21.07.060A.10. g. Minimum Landscaped Open Space. All single-family housing lots shall provide landscaped open space at least equal to 40 percent of the lot area. See SDC 21.07.060A.9.a.v. and SDC 21.07.070 for the definition and provisions for landscaped open space. Critical areas, naturally vegetated areas, and all other landscaped areas shall be counted as landscaped open space provided they are on the applicable lot. h. Minimum Usable Open Space. All residences with garages in the back yard shall provide a contiguous open space equivalent to 10 percent of the lot size. Such open space shall not be located within the front yard. The required open space shall feature a minimum dimension of 15 feet on all sides. For example, a 3,000 square foot lot would require a contiguous open space of at least 300 square feet, or 15 feet by 20 feet in area. Rooftop decks with direct and level access from dwelling units may be used to meet the requirements. Driveways shall not count in the calculations for usable open space. The director may modify this requirement
