1 Limited to single-family detached residences occupied by those engaged in agriculture on the property or operating a stable on the property and accessory dwellings. The density and minimum lot area per dwelling shall not apply to accessory dwellings.
2 Lots smaller than 10 acres shall not be occupied by a dwelling unit or include a residence.
3 Within the Agriculture zone, temporary shelter for soil-dependent cultivation of horticultural or viticulture crops or erosion control during construction or planting shall not be considered a structure or impervious surface for the purposes of determining compliance with this provision. Within the Agriculture zone, properties occupied by commercial green houses may have an additional 10 percent of the site covered by impervious surfaces, provided that the increased impervious surfaces shall only be occupied by the commercial green houses. Any green house flooring shall be constructed in a manner that allows the soil to be returned to civilization.
4 Additional height may be granted to agricultural structures through the special use permit process.
5 Agricultural structures within the shoreline jurisdiction, such as silos and barns, may have a maximum height of 35 feet. Additional height above 35 feet may be granted to agricultural structures within the shoreline jurisdiction through the shoreline variance permit process, provided that structures greater than 35 feet in height are located outside of shoreline view corridors from residential areas located to the east and west of the valley floor.

20C.20.20-050 Bonus for Transferring Residential Densities Outside the Urban Recreation Zone.
(1) Since housing units allowed within the Urban Recreation zone are limited because of the area’s natural hazards, if the units are transferred to property outside the Urban Recreation zone and a legally enforceable provision is recorded against the property zoned Urban Recreation providing that no residences shall be constructed on that land, the housing units allowed by the Urban Recreation zone, including the bonus in this section, Bonus for Transferring Residential Densities Outside the Urban Recreation zone, shall not be restricted to single-family detached residences occupied by those engaged in agriculture on the property or operating a stable on the property and accessory dwellings. The transferred units may be any housing type allowed by Community Development Guide regulations applicable to the property to which the housing units are transferred.
(2) A density bonus of one dwelling unit per 10 acres shall be given if some or all of the housing units allowed within the Urban Recreation zone are transferred to property outside the Urban Recreation zone and a legally enforceable provision is recorded against the property zoned Urban Recreation providing that no residences shall be constructed on that land. Where less than 10 acres is owned in the Urban Recreation zone, a bonus of one housing unit shall be given.
(3) This section, Bonus for Transfer Residential Densities Outside the Urban Recreation Zone, shall not apply to properties within the Agriculture zone or that have deed restrictions, easements, or subdivision restrictions or subdivision notes which prohibit residential use of the property.
