(Ord. No. 11-2011, § 3, 11-28-2011; Ord. No. 7-2022, § 3, 5-23-2022)

A.

Agricultural-Rural (AG) District. The main purpose of the agricultural-rural (AG) district is to provide for all the newly incorporated areas within the town of the size specified in this code and not otherwise designated for some other use, to be included in the AG zone district, as well as to promote the continued and new operation of agricultural operations important to the heritage of the community.

(B)

R-1 Low-Density Residential District. The R-1 low-density residential district is established as a district in which the principal use of land is for single-family dwellings in low density developments of between one and four dwelling units per acre. It is the intention of these regulations to discourage any use which would be detrimental to the single family residential nature of the areas included within the district.

(C)

R-2 General Residential District. The R-2 general residential district is established as a district in which the principal use of land is for residential purposes. A greater coverage of lot area and a medium density of between four and eight dwelling units per acre are encouraged in this district. It is the intention of these regulations to discourage any use which would be detrimental to the residential nature of the areas included within the district.

D.

R-3 Residential/Manufactured/Modular/Factory-Built Housing High Density District. The R-3 residential/manufactured/modular/factory built housing district is established as a district to provide for single-family and multi-family residential development, and permanent manufactured, modular and/or factory built residences. It is the intention of these regulations to encourage any use that would promote the higher density of be-tween eight and sixteen units per acre, and to discourage any use which would be detrimental to the residential nature of the areas included within the district.

E.

Planned Unit Development (PUD) District. The planned unit development (PUD) district is established as a district to accommodate innovative design under unified control or unified plan of development for a number of dwelling units; residential, commercial, educational, recreational, or industrial uses; or any combination thereof. It is the intention of these regulations to encourage development of this type when found to be in conformity with the town's comprehensive plan.

F.

Public Utility District. The public utility district is established as a district in which the principal use of land is for the construction, manufacture, storage and use of municipal facilities and public utilities. It is the intention of these regulations to establish areas within the town for facilities that serve the town with public services, including, without limitation, water and wastewater, irrigation water, maintenance shops, and administrative offices. This district shall encourage the logical expansion of such public services as the town requires due to growth.

G.

B-1 General Business District. The B-1 general business district is established as a district in which the principal use of land is for retail sales and services to the consumer. It is the intention of these regulations to encourage the development and orderly expansion of the district with such uses and in such a manner as to provide ample parking and a minimum of traffic congestion.

H.

B-2 Highway Business District. The B-2 highway business district is established as a district in which the principal use of land is for retail sales and services to the motoring public and other uses not requiring a centralized location, but which do require major highway frontage, comparatively large lot area, and carefully planned outdoor sales and/or open storage reviewed and approved by the town. It is the intention of these regulations to encourage the orderly development and expansion of the district with such uses and in such a manner as to provide ample parking space and a minimum of traffic congestion.

I.

B-3 Business-3 District. The B-3 business-3 district is established as a district in which the principal use of land is for the fabrication, assembly and manufacture of goods and materials in conjunction with related retail and wholesale activities and services to the general public. It is the intention of these regulations to encourage the development and orderly expansion of the district with such uses and in such a manner as to avoid dangerous or unsightly land uses.

J.

Downtown Mixed-Use Overlay (DMD) District:

1.

The downtown mixed-use overlay (DMD) district is established to allow for a transition over time from primarily residential uses in a particular area of town to compatible pedestrian oriented commercial, office, and personal service businesses. This district would be established as an "overlay zone district."

2.

An "overlay zone district" is one that allows all underlying zone district uses to continue while also allowing the new uses specified below, by special use only. Approval of a special use under this chapter shall have the effect of overlaying the existing zoning and thereby adding to and modifying the existing zoning regulations. If a conflict exists between the provisions of the existing zoning description and the special use approved, the regulation of the underlying zone shall apply unless specifically addressed in the provisions of the approved special use permit.

3.

The area defined as the downtown mixed-use overlay zone district is intended to increase the area of the historic downtown and includes most of the civic buildings in the community. By allowing nonresidential uses by special review, the intent is to create a live/work setting to promote small offices, cottage industries, low intensity service businesses and small-scale retail uses in close proximity to living areas. It is not the intent of this district to allow uses that require large parking areas, high-volumes of vehicular traffic or activities that are detrimental to the character of a mix of business and residential activities in the same neighborhood. Architectural character, parking areas, lighting, landscaping, non-motorized access and general business activity should reflect the original residential character of this district.

K.

Business-Industrial (B-I) District. The business-industrial (B-I) commercial district is established as a district in which more intensive commercial uses may be instituted and/or kept, including, but not limited to, fabrication, manufacturing, assembly, processing of natural resources, storage yards and other uses.

L.

OS-Open Space Zone District. The open space zone district is established to provide adequate lands open to the public for active or passive recreational use as well as to protect those lands that are being used for purposes other than open space. This open space district is intended for public and quasi-public open space, parks and other related facilities.

The boundaries of the zone districts provided for in Section 17.12.010 are established as shown on the map entitled "Town of Silt Boundary Map and Zoning Map," adopted by the board and certified by the town clerk.

Where district boundaries are indicated as approximately following the centerlines of streets, alleys, highways, streams, irrigation ditches or rivers, street or railroad right-of-way lines or such lines extended, such lines shall be construed to be such boundaries.

(Ord. 5-05 (part): Ord. 13-80 § 4.03.01)

(Ord. 5-05 (part): Ord. 13-80 § 4.03.02)

Where district boundaries are so indicated that they are approximately parallel to the centerlines of streets, alleys, highways or railroads, or rights-of-way of same, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the zoning map.

(Ord. 5-05 (part): Ord. 13-80 § 4.03.03)

Where a district boundary line divides a parcel in single ownership, the board of adjustment shall determine the correct zoning for the entire parcel, following a public meeting, where the town is presented evidence from the applicant, town staff and the comprehensive plan, or other documents as the town sees fit.

(Ord. 5-05 (part): Ord. 13-80 § 4.03.04)

Where physical or cultural features existing on the ground are at variance with those shown on the zoning map, or in other circumstances not covered previously in this chapter, the board of adjustment shall function as the board of interpretation and interpret the district boundaries at a regularly scheduled meeting, following submittal by the aggrieved party of all those documents that the town administrator or his designee shall determine is necessary.
