Section 55.63 – GENERAL REGULATIONS

The following regulations apply to all uses in this zone unless otherwise noted:

1.    Refer to Chapter 1 KZC to determine what other provisions of this code may apply to the subject property.

2.    All development or associated land surface modifications shall be set back 100 feet from the north boundary of the TL 9B zone.

3.    Vehicular access shall be from the south of the slope. If necessary, for uses other than “A Retail Establishment providing vehicle or boat sales, repair, services, storage or washing,” access may be from 132nd Avenue NE; provided, that such access is limited to one point and meets other City standards.

4.    For residential development:

a.    The base density for residential development on the slope should be eight dwelling units per acre.

b.    Lot coverage for development should be lower than that allowed for the less environmentally sensitive properties to the south, to enable the preservation of vegetation and watercourses on the site.

c.    Vegetative cover should be maintained to the maximum extent possible. Clustering of structures may be required to preserve significant groupings of trees.

d.    Watercourses should be retained in a natural state.

e.    Development should only be permitted if an analysis is presented that concludes that the slope will be stable. The analysis should indicate the ability of the slope and adjacent areas to accommodate development, the best locations for development, and specific structural designs and construction techniques necessary to ensure long-term stability.

f.    The hillside with the steepest slopes should be left undisturbed in a natural condition and retained as permanent natural open space through the creation of a greenbelt easement or the dedication of air rights. In order to provide property owners with reasonable development potential, some development may be permitted on the southern, lower portion of the hillside. In no case should such development or associated land surface modification extend closer than 100 feet to existing single-family residential development north of the slope.

g.    Any part of the hillside which is retained as permanent natural open space, but which has been previously altered from its natural state, or which is so altered as a result of soils testing or watercourse rehabilitation, should be returned to its natural condition.

h.    Surface water runoff should be maintained at predevelopment levels.

i.    Vehicular access should be from south of the slope. If necessary, access may be from 132nd Avenue NE; provided, that such access is limited to one point and meets other City standards.

j.    Where residential uses are allowed, a total of five stories measured above an average building elevation is allowed if at least 10 percent of the units provided are affordable units.
