The urban residential zone is intended to be applied in areas designated as urban residential in the general plan. These areas are served by public water systems. This zone allows the highest density of residential use, taking into consideration neighborhood characteristics and soil capacity for wastewater leaching. The following regulations shall apply in all urban residential zones. [Ord. 166 § 4.06, 1979].

Principal permitted uses are:

A. Single-family dwelling, subject to the requirements of TMC 17.32.090;

B. Home occupation, as provided in TMC 17.56.060. [Ord. 166 § 4.06(A), 1979].

Uses permitted with a use permit in the UR zone include:

A. Guesthouse; servants’ quarters;

B. Removal of trees more than 12 inches dbh. [Ord. 167 § 6, 1980; Ord. 166 § 4.06(B), 1979].

When a septic tank is to be the means of wastewater disposal, new lots shall include sufficient area to accommodate required yards, the intended use, and primary and reserve septic leach fields as determined from requirements in the wastewater disposal regulations adopted by the city. In no case shall a lot be less than 8,000 square feet in area. [Ord. 166 § 4.06(C)(1), 1979].

Maximum density in the UR zone is 8,000 square feet of lot area per dwelling, guesthouse or servants’ quarters. [Ord. 166 § 4.06(C)(2), 1979].

Unless modified by the planning commission as provided in Chapter 17.60 TMC, minimum yards in the UR zone are:

A. Front, 20 feet;

B. Rear, 15 feet;

C. Side, five feet. [Ord. 2001-01 § 5, 2002; Ord. 166 § 4.06(C)(3), 1979].

Maximum building height in the UR zone is 25 feet, except that the planning commission may require a lesser height as provided in Chapter 17.60 TMC. [Ord. 2001-01 § 5, 2002; Ord. 166 § 4.06(C)(4), 1979].

Trees may be removed if they are diseased or pose an imminent danger to people or structures, subject to the approval of the city engineer. Vegetation shall not be removed from a proposed building site until the site is approved by the building inspector. The building inspector shall approve the proposed site only if it involves removal of the least number of trees over 12 inches dbh. The minimum number of trees and shrubs over eight feet in height may be removed for the purpose of improving private or public views subject to the approval of the design assistance committee. [Ord. 166 § 4.06(C)(5), 1979].

Structures, septic disposal systems, driveways, parking areas, pedestrian trails and other improvements permitted in the SR zone shall only be permitted on lands designated as unstable or of questionable stability on Plate 3 of the general plan if analysis by a registered geologist or professional civil engineer with expertise in soils or foundation engineering, or by a certified engineering geologist, at the applicant’s expense, demonstrates to the satisfaction of the planning commission that construction of the development will not significantly increase erosion and slope instability and that any potential adverse impacts have been mitigated to the maximum extent feasible. The geologist’s report shall conform to the requirements of TMC 17.20.130. [Ord. 97-3 § 1, 1997; Ord. 166 § 4.06(C)(6), 1979].
