Grand County Unincorporated
City Zoning Code

All plats and subdivision of land within the unincorporated portion of Grand County shall conform to the following rules and regulations.

No permit for the construction of a building or buildings upon any tract or plot shall be issued until a building site, building tract or building lot has been created by compliance with one (1) of the following conditions:

The lot size, width, depth, shape and orientation, and the minimum building setback lines shall be appropriate for the location of the subdivision and for the type of development and use contemplated and shall not be less than those specified as minimum standards by the zoning district. In addition, such lot configuration shall be in accordance with the General Site Planning Standards of Section 6.9. The depth and width of properties reserved or laid out for commercial and industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated.

Side lot lines shall be substantially at right angles to street lines unless otherwise approved by the Planning Commission.

Each lot or building tract shall front upon a public street.

Double frontage lots shall be avoided, except where essential to provide separation of residential development from traffic or to overcome specific disadvantages of topography and orientation.

Notwithstanding other provisions of this LUC to the contrary, flag shaped or panhandle shaped lots may be created in any zone if all of the following requirements are met:

Where the area is divided into larger lots than for normal County building sites and, in the opinion of the Planning Commission, any or all of the tracts are susceptible of being resubdivided, the original subdivision shall be such that the alignment of future street dedications may conform to the general street layout in the surrounding area and so that the larger tracts may be later subdivided in conformance with the requirements of this LUC and the minimum standards specified by the zoning district.

On and after the passage of these regulations, all developers shall be required to construct asphalt or bituminous asphalt (chip and seal) streets in accordance with requirements of the Grand County Construction Standards. Other materials may be substituted if approved by the County Engineer and Road Supervisor.

Unless otherwise approved by the Planning Commission, provisions shall be made for the extension of streets and in accordance with the requirements of the Grand County Transportation Plan and Grand County Construction Standards. All streets shall bear a logical relationship to the topography and to the location of existing or planned streets on adjacent properties. Adequate local streets shall be provided to accommodate the subdivision and provide access to lots. Where the layout of streets is not shown in the Grand County Transportation Plan, the arrangement of streets in a subdivision shall either:

The system of streets designated for the subdivision, except in unusual cases, must connect with streets already dedicated in adjacent subdivision; and where no adjacent connections are platted, must in general be the reasonable projection of streets in the nearest subdivided tracts, and must be continued to the boundaries of the tract subdivided, so that other subdivisions may connect therewith. Reserve strips of land controlling access to or egress from other property or to or from any street or alley or having the effect of restricting or damaging the adjoining property for subdivision purposes shall not be permitted in any subdivision unless such reserve strips are conveyed to the County in fee simple.

Half Streets shall be prohibited except where essential to the reasonable development of the subdivision and where the Planning and Zoning Commission finds it will be practicable to require the dedication for the other half of a street when adjoining property is subdivided.

More than 2 streets intersecting at a point shall be avoided, except where it is impractical to secure a proper street system otherwise and all intersections shall be as near 90 degrees as possible and in no case shall the intersection angle being less than 60 degrees.

Non-intersecting streets with centerline offset of less than 125 feet shall not be approved.

Dead-end streets, except for cul-de-sacs, shall be prohibited unless they are designed to connect with future streets on adjacent lands that have not been platted. In cases where these types of dead-end streets are allowed, a temporary turnaround with a minimum radius of 50 feet shall be constructed.

Culdesacs shall not exceed 1000 feet in length or serve more than 20 dwelling units and shall have a turn-around diameter of 100 feet, subject to the limitations of the Grand Construction Standards. Ordinarily, cul-de-sacs are discouraged as they do not result in a continuation or conformance to existing streets or streets pattern, and may be used only where unusual drainage or land ownership configurations exist that make other designs impractical.

A Highway Access Permit must be approved by UDOT for each new subdivision with direct access to a state highway. Turn lanes, frontage road(s), curb and gutter may be required along the entire highway frontage if required by UDOT.

Street and alley widths, curves, grades design speed and centerline radius shall meet the Grand Construction Standards, which is summarized, in part, as follows:

Sidewalks shall be 5 feet in width in the NB, Neighborhood Business District and in the GB, General Business District; or 6 feet in width if installed adjacent to a curb. Sidewalks built in all other districts shall be 4 feet in width. The construction specification of all sidewalks will conform to the Grand Construction Standards (maintained in the office of the Grand County Road Superintendent).

Trails in Grand County shall be designed as multi-use trails and shall conform to the following standards:

The developer shall pay the costs of purchasing and installing all street lighting equipment. Street lighting design plans shall be subject to the approval of the County. The type of equipment, method of installation and location of the wiring and light poles shall meet the minimum standards and requirements of the electric company from which electricity is to be purchased. All street lighting shall be shielded and directed toward the ground so as to minimize horizontal view and visibility of the light source. All intersection with a major collector street shall have at least one street light.

Utility easements shall be provided in all residential areas unless otherwise approved by the Planning Commission and in commercial and industrial districts, except that the Planning Commission may waive the requirement where other definite and assured provision is made for service access consistent with and adequate for the uses proposed.

The minimum rights-of-way width of each utility easement shall be 10 feet.

Utility easements shall be provided of 10 feet in width on each side of all rear lot lines and 5 feet in width on each side of side lot lines. Where the rear or side lot lines abut property outside of the subdivision on which there are no rear or side lot line easements at least 5 feet in width, the easements on the rear and side lot lines in the subdivision shall be 10 feet in width.

Water and sewer easements shall be a minimum of 20 feet in width.

Easements 20 feet in width shall be provided in T-intersections and cul-de-sacs for the continuation of utilities or drainage improvements, if necessary.

Fire lanes and emergency access easements 20 feet in width shall be provided where required by the Fire Chief.

When a proposed subdivision is traversed by an irrigation ditch or channel, natural creek or stream or a proposed drainage easement, an easement shall be provided sufficient for drainage and to allow for maintenance of the ditch.

When a proposed subdivision is traversed by a public trail shown on an adopted plan or when the Planning Commission finds that a trail easement can better serve the proposed development than a sidewalk, a 15 feet wide easement shall be provided sufficient for public trail construction, maintenance and access purposes in accordance with the provisions of Section 7.4.

When easements in areas adjoining proposed subdivisions are necessary to provide adequate drainage thereof or to serve such subdivisions with utilities, the developer shall obtain such easements.

A subdivider shall provide, at his expense, drainage structures in accordance with the requirements of the Grand Construction Standards, which will become integral parts of the existing street or roadway drainage system. The dimensions of all drainage structures must be approved by the County Engineer prior to installation. Design shall be based on environmentally sound site planning and engineering techniques. It is especially critical that storm water management systems be designed for an entire drainage basin rather than just for specific sites. If improvements are identified and necessary in the Grand County Storm Drainage Master Plan downstream of the proposed development to Pack or Mill Creek and no approved capital improvement plan exists to addressed the necessary improvement the developer shall be required to demonstrate that such existing drainage features are adequate to serve the anticipated development and to protect the public health, safety, and general welfare at full build out under existing zoning. Where such demonstration is not made, the developer shall be required to install the necessary improvements as identified in the Grand County Storm Drainage Master Plan.

New development shall provide water supply that is sufficient in terms of quality, quantity and dependability for the proposed development. [Where private water systems are proposed, water rights information and water system design and capacity should be provided.] In making its determination as to whether the proposed water supply meets this standard, the decision-making body shall give substantial weight to the recommendations of the Grand County Health Department; the State Engineer; the Department of Environmental Quality, Southeast Utah Division; service provider(s); the County Engineer and other County staff. All water systems in the unincorporated portion of Spanish Valley shall be provided by or through the Grand Water and Sewer Service Agency and meet all applicable requirements of the Grand Construction Standards.

The Grand Water and Sewer Service Agency is hereby designated as the Culinary Water Authority. The written approval of the Culinary Water Authority shall be required prior to the approval of any subdivision plat within the Grand Water and Sewer Service Agencies service area.

If all or part of a proposed development is within 1320 feet of an approved public water system, then the applicant must obtain a written certification from the public water service provider stating that it is able to provide an adequate supply of drinking water with adequate quantity, quality and sufficient pressure to meet the needs of the proposed development based on the projected water usage of the development. Individual or common wells or other private water systems shall be permitted only when the subdivision boundary is more than 1320 feet from the nearest approved public water system able to serve the development.

All subdivisions (except Minor Record Surveys), planned unit developments, commercial developments and industrial developments shall comply with the fire protection standards of this section. New development shall provide fire protection that is sufficient in terms of quality, quantity and dependability for the proposed development. In making its determination as to whether the proposed fire protection system meets this standard, the decision-making body shall give substantial weight to the recommendations of the Local Fire District, service provider(s), the County Engineer and other County staff.

New development shall provide sanitary sewage disposal that is sufficient in terms of quality, quantity and dependability for the proposed development. In making its determination as to whether the proposed sewage disposal plan meets this standard, the decision-making body shall give substantial weight to the recommendations of the Grand County Health Department, service provider(s), County Engineer, and other County staff.

The Grand Water and Sewer Service Agency is hereby designated as the Sanitary Sewer Authority. The written approval of the Sanitary Sewer Authority shall be required prior to the approval of any subdivision plat within the Grand Water and Sewer Service Agencies service area.

If all or part of a proposed development is within 1320 feet of an approved public sewer system, then the applicant must obtain a written certification from the public sewer service provider stating that it is able to provide sewer service to meet the needs of the proposed development. Individual septic tank systems, or other private sewage systems, shall be permitted only when the nearest point of the subdivision boundary is more than 1320 feet from an existing approved sanitary sewer system, except that no septic systems shall be permitted within the boundaries of the Valley Aquifer Impact Zone. All sanitary sewer service and facilities in the Spanish Valley provided by or through a sewer improvement district or a municipal system shall comply with all applicable requirements of the Grand Construction Standards or municipal service requirements, as appropriate.

All utilities shall be placed underground, except transformers, switching boxes, and terminal boxes.
