A.

Purpose of the R4 Zoning District.

1.

The purposes of the R4 single-family residential zone are to:

a.

Implement the comprehensive plan policies that result in the creation of neighborhoods of single-family detached houses consistent with the residential design guidelines;

b.

Provide for suburban residential neighborhoods that have a full range of public services and facilities while allowing nonresidential uses that complement the residential nature of these zones;

c.

Promote diversity in the size and type of new single-family developments to provide housing opportunities for various family sizes and incomes in Duvall.

2.

This zone is appropriate where designated by the comprehensive plan and when such areas are served at the time of development by adequate public sewers, water supply, roads, and other needed public facilities and services. These zones are also appropriate where the surrounding lands have already been developed with lower density single-family detached housing.

3.

R4 zoned properties are those residential lands that were designated as "Suburban Housing Densities" in the 1994 comprehensive plan and zoned R3 on the City of Duvall zoning map in effect on November 23, 2004. The zoning on these properties was increased from three to four units per acre through the adoption of the official zoning map.

B.

Permitted Uses. Allowed uses are those uses that are permitted in the R4 zoning district. Such uses are:

1.

Accessory dwelling unit (see DMC Chapter 14.48);

2.

Adult family home;

3.

Cottage units constructed as part of a cottage housing development;

4.

Dwelling unit, detached;

5.

Park, public or private;

6.

Pea-patches;

7.

Recreational trail, nonmotorized;

8.

Wireless facilities attached to an existing building or structure and camouflaged (see DMC Chapter 14.56).

C.

Development Standards. The following development standards specifically apply to the R4 zoning district.

Table 14.12.050.C

1. Porches and stoops may project up to two feet into the required front yard setback. This provision provides incentives for porches without taking up building envelope space for the dwelling unit.

2. Garages must be set back a minimum of twenty (20) feet (fifteen (15) feet for side entry garage) from the designated property line, and or back of sidewalk. This ensures sufficient space for cars to park in driveways without blocking sidewalks. See residential design standards for garage setback/differentiation from house.

3. The minimum setback for any one side is five feet. Side setbacks for accessory structures are five feet for all residential zones. Example: five feet on one side requires ten (10) feet on the other side.

4. The setback requirement is intended for sixteen (16) to twenty (20) foot alleys and tracts.

5. See DMC Section 14.42.090, Density credits.

6. The floor area ratio shall exclude garages and basements from the measurement. Example: 6,000 square foot lot x 50% = 3,000 square foot maximum house size.

7. The minimum lot width circle identifies the minimum lot width circle diameter that must fit within each newly created lot for each residential zone. This circle establishes that at least some portion of a lot must be at least as wide as the minimum lot width. The lot width circle shall not include streams, floodways, wetlands, or steep slopes. See Figure 14.12.050.C.1.

8. Minimum lot frontage is the minimum width of a lot where it shall adjoin a street or approved access corridor. For individual flag lots, lot frontage is measured where the access corridor meets the street. See Figure 14.12.050.C.2.

9. See DMC Section 14.64.130 for calculating building height.

10. Two floors allowed on the uphill side and three floors allowed on the downhill side.

11. Projects using the binding site plan process for residential units shall meet the same setbacks.

 * Subtract right-of-way. Example: 100,000 square feet - 20,000 square feet of ROW = 80,000 square feet X 75% = 60,000 square feet of impervious coverage allowed.

12. Detached accessory dwelling units may be located at a lot line if the lot line abuts a public alley.
