f. Retaining Wall
Open space with natural landscape features can provide for a variety of functions including for wildlife habitat, active and passive recreation, trails, and can be integrated with stormwater and green infrastructure. The Open Space arterial frontage may be used to satisfy the requirements for on-site recreation requirements in SDC 21.02.030M. or be dedicated to the City for parks or open space at the City’s discretion. The Open Space arterial frontage must be a minimum depth of 100’.
On parcels and sites existing prior to December 31, 2021, the use a retaining wall may be an appropriate design on sloped sites. Retaining walls are limited to four feet in height, and the front of the house or unit must face the arterial street if within 100’ from the public right-of-way. Vehicle access must be taken from a non-arterial street unless determined to be infeasible by the City. This frontage type does not apply to subdivision applications and is only for lots existing prior to the adoption of arterial frontage standards.
