(A)
Purpose. The purpose of this chapter is to establish dimensional standards for development. These standards are established to provide flexibility in project design and promote high-quality development within the city.
(C)
Setback Height and Coverage Standards. Chapter 19.03 GFMC sets forth the required development standards for the zones.
(1)
Setback Measurement. A setback is measured from the edge of a street right-of-way, access easement or private road. Where there is no street right-of-way, access easement or private road, a setback is measured from the property line.
(2)
Designation of Required Setbacks. All lots except pipestem lots must contain at least one front yard setback. All lots must contain one rear yard setback except for corner, through, and pipestem lots. All other setbacks will be considered interior yard setbacks.
(3)
Corner Lots. If a lot abuts the intersection of two or more street rights-of-way, a front yard setback is required abutting each right-of-way.
(4)
Through Lots. In the case of a through lot, a front yard setback is required abutting each street right-of-way.
(5)
Front Yard Setback Averaging. Averaging may be used to reduce a front yard setback requirement when a principal building has been established on an adjacent lot with less than the standard required setback. This provision shall not apply if the adjacent lot has received a reduced setback based upon a discretionary land use approval. This exception shall be calculated as follows:
(a)
Averaging shall be calculated by adding the existing front yard setbacks of the adjacent lots together and dividing that figure by two.
(b)
When an adjacent lot is vacant, averaging shall be calculated by adding the front yard setback of the adjacent developed lot with the minimum front yard setback of the zone in which the construction is proposed and dividing that figure by two.
(6)
Slopes. If the topography of a lot is such that the minimum front yard setback line is eight feet or more above the street grade, and there is no reasonable way to construct a driveway up to the dwelling unit level, a garage/carport may be built into the bank and set at least five feet back from the right-of-way.
(7)
Accessory Structures – Interior Yard Exception. Detached one-story accessory structures may occupy 25 percent of the total area of a side yard (that portion of the yard exclusive of required setbacks).
(8)
Accessory Structures – Rear Yard Exception. Detached one-story accessory structures may occupy 50 percent of the total area of a rear yard and shall maintain a minimum five-foot setback, except in the DT-2,500 zones.
(9)
Bus Shelters. Bus shelters for school district or transit authority purposes may be located within a front yard setback when located on private property if they do not exceed 50 square feet of floor area and one story in height, provided all applicable site distance requirements are met.
(10)
Projection Exception.
(a)
Fireplace structures, bay or garden windows, enclosed stair landings, ornamental features, or similar structures may project into any setback, provided such projections are:
(b)
Uncovered porches and decks which do not exceed 33 inches from finished lot grade may project into any setback, provided such projections do not extend more than six feet into a front yard setback or 18 inches into a side yard setback.
(c)
Wheelchair ramps may project into any required setback.
(11)
Rear Yards – Exception. In the case of triangular or otherwise irregularly shaped lots, a line 10 feet in length entirely within the lot, parallel to and at a maximum distance from the front lot line, may be considered the "rear lot line."
(D)
Height Standards. (See Figure 1 set forth in subsection (D)(2) of this section for measuring building heights.)
(1)
Measurement. The height of a fence located on a rockery, retaining wall, or berm shall be measured from the top of the fence to the ground on the high side of the rockery, retaining wall, or berm.
(a)
Walls, fences, and berms up to three feet in height may be located on any part of a lot. Open fences may be up to four feet in height.
(b)
Walls, fences and berms up to six feet in height may be located to the rear of the front wall line of the principal residence unless otherwise determined to provide a site distance hazard by the building inspector.
(c)
The provisions of this section shall not apply to fences required by state law to surround public utility installations, or to fences enclosing school grounds and public playgrounds. A building permit shall be required for construction of any wall or fence over six feet in height located within the city.
(2)
Exceptions. Height standards shall not apply to the following:
(a)
Church spires, belfries, domes, chimneys, antennas, satellite dishes, ventilation stacks, or similar structures, provided the structure is set back from all property lines a distance equal to the height of the structure.
(b)
Rooftop Mechanical Equipment. All rooftop mechanical equipment may extend 10 feet above the height limit of the zone, provided all equipment is set back 10 feet from the edge of the roof.
(c)
Utility towers are subject to review of site location.
(E)
General Development Standards.
(1)
Existing Lot – Single-Family Dwelling Permitted. In any zone that permits a single-family dwelling unit, a single-family dwelling unit and permitted accessory structures may be constructed or enlarged on one lot which cannot satisfy the density requirements of the zone where the lot was legally created prior to the effective date of this regulation. This section shall not waive the requirements for setbacks and height of the zone in which the lot is located.
(2)
Combining Lots – Interior Yard Setback Exception. Where two or more lots are used as a building site and where principal buildings cross lot lines, interior yard setbacks shall not be required from those lot lines crossed by the principal building.
(3)
Legally Created Lots – Development Permitted Proof.
(a)
Development shall be permitted only on legally created lots.
(b)
To establish that a lot has been legally created, the applicant must provide one of the following:
(i)
A copy of formal plat, short plat, or large lot subdivision approved by Granite Falls separately describing the lot.
(ii)
A copy of the boundary line adjustment or lot combination separately describing the lot.
(iii)
Documentation that the creation of the lot was exempt from the provisions of the subdivision title.
(iv)
A deed, contract of sale, mortgage, recorded survey, or tax segregation that separately describes the lot.
(c)
Pipestem (Flag) Lots. Pipestem (flag) lots are allowed in the R-2.3, R-9,600 and R-7,200 zones. Pipestem (flag) lots may be approved subject to the criteria provided in this code.
(d)
Bulkheads and Retaining Walls. Any structure constructed and erected between lands of different elevations used to resist the lateral displacement of any material, control erosion, or protect structures may be placed within required setbacks to a maximum height of six feet, provided all applicable site distance requirements are met.
(4)
Development Standards for All Pipestem (Flag) Lots. All pipestem (flag) lots, irrespective of when platted, shall meet the following standards, subject to site plan review:
(a)
All development of principal residences, accessory dwellings, garages, sheds, and other structures shall be built within the required setbacks.
(b)
The "building area" within the setbacks shall be large enough to accommodate a 40-foot-diameter building circle to ensure that the shape of the lot is adequate to support development that results in attractive, usable open spaces.
(c)
The perimeter treatment of the lot including the driveway portion may include fencing or landscaping to screen the development from adjacent properties.
(d)
The maximum length of a "flag" shall be 200 feet.
(5)
Sanitary Sewer Connection. All new developments requiring sanitary sewer facilities must connect to a public sewer system if the system is within 200 feet of the property line. If not within 200 feet, the development must connect at the time that public sewer becomes available to any property served by a private sewage disposal system. This connection must be made within 90 days of sewer availability.
Any existing septic system that fails to meet Snohomish health district standards must be repaired or replaced within 90 days of failure.
(6)
Stormwater Drainage and Water Quality. All development shall comply with the Department of Ecology's 2005 Stormwater Management Manual for Western Washington and revisions thereto.
