11-02-04: INDUSTRIAL ZONING DISTRICTS:

   1.   I-1: Industrial: Light:

      A.    Purpose: The I-1 zoning district is intended to accommodate light manufacturing, assembly, fabrication, and technology-related land uses that may require significant transportation services but that typically do not operate during nighttime hours and are generally compatible with nearby commercial and residential areas when accompanied by substantial buffering, screening, and standards designed to mitigate impacts.

The following table is a summary of the district-specific dimensional standards. Complete dimensional standards are included in Section 11-04-03, Lot and Building Design and Dimensions.

      D.   Streetscape Standards: All new development or an intensification of the development, shall comply with the following streetscape standards. The stricter provisions shall supersede any inconsistent dimensional standards in Section 11-04-07, Access and Connectivity.

         (1)   Each frontage on a local street shall include a detached sidewalk at least five feet in width that is separated from the curb line by a minimum of eight to 10 feet when a Class I, II, or III street tree is provided depending on the site conditions. This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

   (2)   Each frontage on a collector or arterial street shall include a detached sidewalk at least 10 feet in width that is separated from the curb line by a minimum of eight to 10 feet when a Class I, II or III street tree is provided depending on the site conditions. This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

      E.    Additional Standards:

         (1)   No uses that generate, use, treat, store, or dispose of hazardous substan ces (as set forth in Title 40, Code of Federal Regulations, Parts 116.4, 261.30 et seq., 302.4 and/or 355) are permitted.

         (2)   All operations creating odor, dust, smoke, cinders, gas, fumes, noise, vibrations, refuse matter, water-carried waste, or other emissions shall be reasonably mitigated to protect the health, safety, and general welfare of the surrounding land uses.

   2.   I-2: Industrial: Heavy:

      A.   Purpose: The I-2 zoning district is intended to accommodate general industrial activity with greater impacts than those in the I-1 zoning district, including uses that require significant heavy transportation services, uses that frequently operate during nighttime hours, and uses that require additional standards to protect health, safety, or general welfare. The I-2 zoning district should be separated from commercial or residential development.

      B.   Cross-References to Other Applicable Code Sections: All development shall comply with all applicable sections of this Code. Cross-references to some of the key sections are provided below.

      C.   Dimensional Standards:

The following table is a summary of the district-specific dimensional standards. Complete dimensional standards are included in Section 11-04-03, Lot and Building Design and Dimensions.

      D.   Streetscape Standards: All new development or an intensification of the development, shall comply with the following streetscape standards. The stricter provisions shall supersede any inconsistent dimensional standards in Section 11-04-07, Access and Connectivity.

         (1)   Each frontage on a local street shall include a detached sidewalk at least five feet in width that is separated from the curb line by a minimum of eight to 10 feet when a Class I, II, or III street tree is provided depending on the site conditions. This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

   (2)   Each frontage on a collector or arterial street shall include a detached sidewalk at least 10 feet in width that is separated from the curb line by a minimum of eight to 10 feet when a Class I, II or III street tree is provided depending on the site conditions. This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

      E.   Additional Standards: All Allowed Uses that generate, use, treat, store, or dispose of hazardous substances (as set forth in Title 40, Code of Federal Regulations, Parts 116.4, 261.30 et seq., 302.4 and/or 355), shall require a Conditional Use Permit.

   3.   I-3: Industrial: Technology:

      A.   Purpose: The I-3 zoning district is intended to provide for manufacturing and technological facilities that may have a greater impact on the surrounding area than industries allowed in the Mixed-Use zoning districts. Lands in the I-3 zoning district should be served by major transportati on facilities and be buffered from adjacent residential areas.

      B.   Cross-References to Other Applicable Code Sections: All development shall comply with all applicable sections of this Code. Cross-references to some of the key sections are provided below.

   C.    Dimensional Standards:

The following table is a summary of the district-specific dimensional standards. Complete dimensional standards are included in Section 11-04-03, Lot and Building Design and Dimensions.

      D.   Streetscape Standards: All new development or an intensification of the development, shall comply with the following streetscape standards. The stricter provisions shall supersede any inconsistent dimensional standards in Section 11-04-07, Access and Connectivity.

         (1)   Each frontage on a local street shall include a detached sidewalk at least five feet in width that is separated from the curb line by a minimum of eight to 10 feet when a Class I, II, or III street tree is provided depending on the site conditions. This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

This area will accommodate a landscape buffer and street trees required by Section 11-04-09.4, Street Frontage Landscaping. Class I trees are permitted only when overhead powerlines are present.

      E.    Additional Standards:

         (1)    Operational Standards:

            (a)    No uses that generate, use, treat, store, or dispose of hazardous substances (as set forth in Title 40, Code of Federal Regulations, Parts 116.4, 261.30 et seq., 302.4 and/or 355) are permitted.

            (b)   All operations shall be free of odor, dust, smoke, cinders, gas, fumes, noise, vibrations, refuse matter, water-carried waste, or other emissions.

         (2)   Design Review:

            (a)   To mitigate potential negative impacts on adjacent development, a concept map differentiating "peripheral" and "internal" development areas is required as part of an application to rezone to I-3. Areas approved as "peripheral" shall be subject to Major Design Review pursuant to Section 11-05-05.3.D.

            (b)   Because these developments are usually large enough to create an inner character compatible with surrounding uses, areas approved as "internal" shall be exempt from the design review process, unless otherwise required by this Section.

            (c)   Buildings taller than 45 feet in an area designated "internal" are subject to Design Review. The Planning Director may waive this requirement where it can be demonstrated that there are no material negative impacts associated with such buildings due to the proximity of surrounding buildings or structures.
