Silvis City Zoning Code

ARTICLE IV

SPECIAL PROVISIONS AND STANDARDS

Sec. 102-516.- Maximum height limitations.

(a)

In any zoning district, the maximum height of any building shall be limited by the standards listed in table I, section 102-519, in order to protect the visual integrity of residential areas, to protect solar access and to ensure that buildings are within the range of firefighting apparatus.

(b)

Exceptions to building height limits may be granted when the proportion of the building proposed above the regulation height is not used for residential purposes and has an internal sprinkler system approved by the fire chief or does not contain combustible materials or is needed to permit solar energy collectors.

(Code 1976, § 29-90)

Sec. 102-517. - Lot and yard requirements.

In any zoning district, the minimum lot and yard dimension shall be limited by the standards listed in table I, section 102-519. These standards establish maximum densities of buildings and minimum separation of buildings to preserve the character of established neighborhoods and developing areas, to ensure accessibility to all parts of the building in emergencies, to prevent fire from spreading from one building to another, to ensure that adequate open space and yards are provided for each dwelling unit, and to provide adequate space for buffer areas and screening between incompatible uses.

(Code 1976, § 29-91)

Sec. 102-518. - Minimum lot and yard dimensions on irregular shaped lots.

The code enforcement officer shall determine the yard requirements on irregularly shaped lots, but in no case shall the yard be less than the minimum permitted in the zoning district. These setbacks shall generally follow parallel to the shape of the lot, but in no case shall the distance between the front and rear yards be less than 40 feet or the distance between the side yards be less than 40 feet.

(Code 1976, § 29-92)

Sec. 102-519. - Maximum lot coverage.

(a)

In any zoning district, no lot shall be covered with surface or material that is impermeable to rain more than the percent allowed in table I in this section, but in no case shall stormwater drainage exceed that allowed under subsection 102-12(b). This reduces the amount of stormwater that could runoff of the lot due to building, driveway, patios, and sidewalk surfaces, and maintains a minimum amount of open space and landscape area.

(b)

Upon review, the percentage of lot coverage may be reduced through the variance procedure when the lot is substandard and the use proposed requires additional area of impervious surface, but in no case shall the rate of discharge of stormwater exceed that allowed under subsection 102-12(b).
