311-7 Designation and Adoption of Zoning Maps

7.1The designation, location and boundaries of the zones shall be made by written description or by delineation on zoning maps which may be adopted or amended as provided in Chapter 2 of this division. (Former Section CZ#A311-8; Ord. 1705, 9/10/85)

7.2The maps and all notations, references, data and other information shown thereon shall be a part of, and subject to all of the requirements of this Code, and shall supersede all maps, notations, references, data and other information which are incorporated or referenced in any prior zoning maps of the County Code. Although the zoning maps and written legal descriptions of property within the County of Humboldt are not included in the text of this Code, they are incorporated herein by reference. (Former Section INL#313-3, INL#313-4; CZ#A311-8, CZ#A311-9; Ord. 519, Sec. 303, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

311-8 Uncertainties in Zone Boundaries: How to Resolve

Where uncertainty exists as to the boundaries of any districts shown on the zoning maps, the Hearing Officer, in reviewing a discretionary permit, shall apply the following rules to resolve such uncertainty: (Former Section INL#313-5; CZ#A311-10; Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

8.1 STREETS OR ALLEYS

Where zoning district boundaries approximately follow lot, alley, or street lines, such lot lines and street and alley centerlines shall be construed as the zone district boundaries unless said boundaries are otherwise indicated. (Former Section INL#313-5(a); CZ#A311-10 (A); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85)

8.2 SCALE ON MAP; DETERMINATION BY COMMISSION

Where the property is indicated on a zoning map or maps as acreage and not subdivided into lots and blocks, or where the zone boundary lines are not approximately street, alley or lot lines, the zone boundary lines on said zoning map or maps shall be determined by scale contained on such map or maps, and where uncertainty exists, the zone boundary line shall be determined by the Planning Commission. In the event property shown as acreage on the zoning map or maps has been or is subsequently subdivided into lots or lot and block arrangement does not conform to that anticipated when the zone boundaries were established, the Planning Commission, after notice to the owners of the property affected thereby, may interpret the zone maps in such a way as to implement the intent and purpose of these regulations and conform to the street, block and lot layout on the ground. Such interpretation shall be by written decision, and thereafter the copies of the zoning maps shall be changed to conform thereto. (Former Section INL#313-5(c); CZ#A311-10 (B); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

8.3 VACATED STREET OR ALLEY

Where a public street or alley is officially vacated or abandoned, the property formerly in said street or alley shall be included within the zone district or districts of the adjoining property on either side of said vacated or abandoned street or alley centerline. (Former Section INL#313-5(d); CZ#A311-10(C); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85)

8.4Where a boundary line follows the bank of a watercourse, it shall be construed as following the top edge of the nearest bank, or if there is no identifiable bank, the stream transition line. (Former Section CZ#A311-10 (D); Ord. 1705, 9/10/85)

8.5Where a boundary line is indicated as following a watercourse, it shall be construed as the centerline of the watercourse. (Former Section CZ#A311-10 (E); Ord. 1705, 9/10/85)

8.6Where further uncertainty exists, the Planning Commission, upon written application or on its own motion, shall determine the location of the boundary in question, giving due consideration to the location indicated on the Zoning Map and the purposes set forth in the Principal Zone district regulations. (Former Section CZ#A311-10 (F); Ord. 1705, 9/10/85)

311-9 How the Provisions of This Code Relate to Each Other and to Other Provisions of Law

9.1All other provisions of law still apply. Unless otherwise specifically provided, no provision of these Zoning Regulations shall be construed as relieving any party to whom a development permit, license, or variance is issued, from any other provision of State or Federal Law or from any provision, ordinance, rule, or regulation of Humboldt County requiring a license, franchise, or permit to accomplish, engage in, carry on or maintain a particular business, enterprise, occupation, transaction or use. (Former Section CZ#A311-11; Ord. 1705, 9/10/85)

9.2Each provision of this code is severable and independent. If any section, subsection, sentence, clause or phrase of these regulations is for any reason held to be invalid or unconstitutional, such invalidity or unconstitutionality shall not affect the validity or constitutionality of the remaining portions of these regulations. It is hereby expressly declared that this ordinance and each section, subsection, sentence, clause and phrase hereof would have been prepared, proposed, adopted, approved and ratified irrespective of the fact that any one (1) or more other sections, subsections, sentences, clauses or phrases be declared invalid or unconstitutional. (Former Section CZ#A311-12; Ord. 1705, 9/10/85)

9.3These regulations supersede other existing code sections previously adopted. These Regulations supersede the existing zoning regulations, as amended, of the County of Humboldt, for land which lies within the unincorporated areas of the County. If any provisions of these Regulations should be determined to be invalid or inapplicable, the provisions of the most recently adopted pre-existing zoning regulations shall apply. (Former Section CZ#A311-13; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

9.4These Regulations shall not be construed as validating or legalizing any building, structure or land use conducted, constructed, erected, or maintained in violation of any Federal, State or Humboldt County ordinance. Insofar as the provisions of these regulations impose the same regulations as those imposed by existing zoning regulations, this ordinance shall be construed as a continuation of said regulations and not as a new enactment. (Former Section CZ#A311-13; Ord. 1705, 9/10/85)

311-7 Designation and Adoption of Zoning Maps

7.1The designation, location and boundaries of the zones shall be made by written description or by delineation on zoning maps which may be adopted or amended as provided in Chapter 2 of this division. (Former Section CZ#A311-8; Ord. 1705, 9/10/85)

7.2The maps and all notations, references, data and other information shown thereon shall be a part of, and subject to all of the requirements of this Code, and shall supersede all maps, notations, references, data and other information which are incorporated or referenced in any prior zoning maps of the County Code. Although the zoning maps and written legal descriptions of property within the County of Humboldt are not included in the text of this Code, they are incorporated herein by reference. (Former Section INL#313-3, INL#313-4; CZ#A311-8, CZ#A311-9; Ord. 519, Sec. 303, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

311-8 Uncertainties in Zone Boundaries: How to Resolve

Where uncertainty exists as to the boundaries of any districts shown on the zoning maps, the Hearing Officer, in reviewing a discretionary permit, shall apply the following rules to resolve such uncertainty: (Former Section INL#313-5; CZ#A311-10; Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

8.1 STREETS OR ALLEYS

Where zoning district boundaries approximately follow lot, alley, or street lines, such lot lines and street and alley centerlines shall be construed as the zone district boundaries unless said boundaries are otherwise indicated. (Former Section INL#313-5(a); CZ#A311-10 (A); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85)

8.2 SCALE ON MAP; DETERMINATION BY COMMISSION

Where the property is indicated on a zoning map or maps as acreage and not subdivided into lots and blocks, or where the zone boundary lines are not approximately street, alley or lot lines, the zone boundary lines on said zoning map or maps shall be determined by scale contained on such map or maps, and where uncertainty exists, the zone boundary line shall be determined by the Planning Commission. In the event property shown as acreage on the zoning map or maps has been or is subsequently subdivided into lots or lot and block arrangement does not conform to that anticipated when the zone boundaries were established, the Planning Commission, after notice to the owners of the property affected thereby, may interpret the zone maps in such a way as to implement the intent and purpose of these regulations and conform to the street, block and lot layout on the ground. Such interpretation shall be by written decision, and thereafter the copies of the zoning maps shall be changed to conform thereto. (Former Section INL#313-5(c); CZ#A311-10 (B); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

8.3 VACATED STREET OR ALLEY

Where a public street or alley is officially vacated or abandoned, the property formerly in said street or alley shall be included within the zone district or districts of the adjoining property on either side of said vacated or abandoned street or alley centerline. (Former Section INL#313-5(d); CZ#A311-10(C); Ord. 519, Sec. 305, 5/11/65; Ord. 1705, 9/10/85)

8.4Where a boundary line follows the bank of a watercourse, it shall be construed as following the top edge of the nearest bank, or if there is no identifiable bank, the stream transition line. (Former Section CZ#A311-10 (D); Ord. 1705, 9/10/85)

8.5Where a boundary line is indicated as following a watercourse, it shall be construed as the centerline of the watercourse. (Former Section CZ#A311-10 (E); Ord. 1705, 9/10/85)

8.6Where further uncertainty exists, the Planning Commission, upon written application or on its own motion, shall determine the location of the boundary in question, giving due consideration to the location indicated on the Zoning Map and the purposes set forth in the Principal Zone district regulations. (Former Section CZ#A311-10 (F); Ord. 1705, 9/10/85)

311-9 How the Provisions of This Code Relate to Each Other and to Other Provisions of Law

9.1All other provisions of law still apply. Unless otherwise specifically provided, no provision of these Zoning Regulations shall be construed as relieving any party to whom a development permit, license, or variance is issued, from any other provision of State or Federal Law or from any provision, ordinance, rule, or regulation of Humboldt County requiring a license, franchise, or permit to accomplish, engage in, carry on or maintain a particular business, enterprise, occupation, transaction or use. (Former Section CZ#A311-11; Ord. 1705, 9/10/85)

9.2Each provision of this code is severable and independent. If any section, subsection, sentence, clause or phrase of these regulations is for any reason held to be invalid or unconstitutional, such invalidity or unconstitutionality shall not affect the validity or constitutionality of the remaining portions of these regulations. It is hereby expressly declared that this ordinance and each section, subsection, sentence, clause and phrase hereof would have been prepared, proposed, adopted, approved and ratified irrespective of the fact that any one (1) or more other sections, subsections, sentences, clauses or phrases be declared invalid or unconstitutional. (Former Section CZ#A311-12; Ord. 1705, 9/10/85)

9.3These regulations supersede other existing code sections previously adopted. These Regulations supersede the existing zoning regulations, as amended, of the County of Humboldt, for land which lies within the unincorporated areas of the County. If any provisions of these Regulations should be determined to be invalid or inapplicable, the provisions of the most recently adopted pre-existing zoning regulations shall apply. (Former Section CZ#A311-13; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

9.4These Regulations shall not be construed as validating or legalizing any building, structure or land use conducted, constructed, erected, or maintained in violation of any Federal, State or Humboldt County ordinance. Insofar as the provisions of these regulations impose the same regulations as those imposed by existing zoning regulations, this ordinance shall be construed as a continuation of said regulations and not as a new enactment. (Former Section CZ#A311-13; Ord. 1705, 9/10/85)

311-10 Limitations on Land Uses and Structures

Except as otherwise specifically provided in this Code:

10.1 USE REQUIREMENTS

(Former Section INL#313-7(a); Ord. 519, Sec. 307, 5/11/65; Amended by Ord. 2214, 6/6/00)

10.2 HEIGHT REQUIREMENTS

No building or part thereof or structure shall be erected, reconstructed or structurally altered to exceed in height the limit hereinafter designated for the zone in which such building is located except as otherwise specifically provided in this Code.

10.3 AREA REQUIREMENTS

No building or part thereof or structure shall be erected nor shall any existing building be altered, enlarged or rebuilt or moved into any zone, nor shall any open space be encroached upon or reduced in any manner, except in conformity to the yard, building site area, and building location regulations hereinafter designated for the zone in which such building or open space is located. (Former Section INL#313-7(c); Ord. 519, Sec. 307, 5/11/65; Amended by Ord. 2214, 6/6/00)

10.4 DUPLICATE USE OF OPEN SPACE AND YARDS

No yard or other spaces provided about any buildings for the purpose of complying with provisions of this division shall be considered as providing a yard or open space for any other building, and no yard or other open space on one building site shall be considered as providing a yard or open space for a building on any other building site unless specifically permitted elsewhere in this Code. (Former Section INL#313-7(d); Ord. 519, Sec. 307, 5/11/65; Amended by Ord. 2214, 6/6/00)

311-11 Completion of Existing Buildings When the Regulations Change

11.1These regulations do not require any change in the plans, construction or designated use of a building or structure for which a Coastal Development Permit has been issued by the Coastal Commission, or to any permit issued by the County prior to the effective date of these Regulations or any amendment of these regulations, provided that actual construction of such building or structure is commenced within 120 days after the date of issuance of the permit, and is completed within one (1) year from the effective date of such adoption or amendment. (Former Section CZ#A311-14; Ord. 1705, 9/10/85; Amended by Ord. 2214, 6/6/00)

11.2Actual construction is hereby defined to be the actual placing of construction materials in their permanent position, fastened in a permanent manner, except that where a basement is being excavated such excavation shall be deemed to be actual construction, or where demolition or removal of an existing structure has begun preparatory to rebuilding, such demolition or removal shall be deemed to be actual construction. (Former Section CZ#A311-14; Ord. 1705, 9/10/85)
