(Prior code 9-3-5; Ord. 956 § 1, 2014)
This provision for temporary uses and structures is intended only to accommodate the need for special exceptions to the zoning regulations and other applicable provisions of this Code during or resulting from officially declared local disasters or emergencies pursuant to Section 24-33.5-709, C.R.S., to provide immediate temporary relief from the direct and indirect damage to land, structures, businesses and supporting infra-structure. The principal purpose is to mitigate the loss of use and promote the rapid restoration of beneficial economic use of property that has suffered direct or indirect damage, including economic damage, due to flood, fire or other natural or manmade disaster. This Section authorizes the Town Administrator to issue permits in any zone for the temporary use of property that will aid in the immediate restoration of an area adversely impacted by a major disaster. The authorization of temporary uses and structures under this Section is intended to promote the recovery of damaged land and structures, accommodating necessary short-term transitional economic uses not otherwise provided for within the underlying zoning, to aid in the eventual restoration of permanent beneficial use consistent with the underlying zoning or proposed site specific master plan that advances the goals and objectives of the Comprehensive Plan. The Town Administrator shall have the authority to administer the provisions of this Section temporarily waiving or modifying provisions of this Code concerning building permits, demolition permits and restrictions on the use, development or occupancy of private property, provided that such action, in the opinion of the Town Administrator, is reasonably justifiable for the protection of life and property, mitigation of hazardous conditions, avoidance of undue displacement of households or businesses or prompt restoration of public infrastructure.
(1)
Critical facilities. Any police, fire, emergency medical, emergency communications facility or other critical municipal or public facility that may aid in the immediate restoration of the area may be permitted in any zone for a period not to exceed two (2) years from date of declaration of emergency.
(2)
Required findings. Other temporary uses: Temporary use permits may be issued in any zone, with conditions, as necessary, provided that written findings are made establishing a factual basis that the proposed temporary use: 1) will not be detrimental to the immediate neighborhood; 2) will not adversely affect the Comprehensive General Plan or any applicable specific plan; and 3) will contribute in a positive way to the reconstruction and recovery of areas adversely impacted by the disaster.
a.
Applicability. All applicants shall show a clear and immediate need for accommodation under this provision due to the direct or indirect damage to land, structures or business operations resulting from any officially declared disaster or emergency. All temporary uses and structures shall obtain a temporary use permit pursuant to the procedures set forth in this Section.
b.
Procedures for approval of temporary uses and structures. The procedure for an application for a temporary use or structure shall be as follows:
1.
Step 1: Pre-Application Conference. A pre-application conference is required for temporary use or structure applications under this provision. The applicant shall provide a written statement of intent that identifies the need for accommodation under this provision. Where the proposed temporary use does not conform to the underlying zoning, it shall be the applicant's responsibility to provide a written explanation of the beneficial nature of the requested temporary use as a temporary and transitional means to return to a conforming use. This may include a plan to re-zone the property in response to the changed circumstances resulting from the disaster to accommodate a use that will advance the goals and objectives of the Comprehensive Plan. The applicant shall establish the necessary connection between the temporary use as a bridge to the establishment of a permanent use.
2.
Step 2: Notice to Adjacent Property Owners of Application. The site shall be posted with a notice of the application provided by the Town for a period of at least seven (7) days before approval and issuance of a temporary use permit. Staff may also require written notice to be mailed to adjacent property owners. If so, the applicant shall provide the Town Clerk with one (1) set of stamped, addressed, certified (return receipt requested) envelopes. The envelopes shall have the Town's address as the return address and the envelopes shall be addressed to the surrounding property owners within three hundred (300) feet of the property and to any referral agencies identified by the Staff.
3.
Step 3: Staff Review and Action. Within thirty (30) days from the date a complete application is submitted and notice is posted, the Staff shall review the application according to the standards set forth in this Section and shall make a final decision to approve, approve with conditions or deny the application.
c.
Standards for review. The Staff shall review an application for a temporary use or structure and evaluate it for compliance with the following standards (as applicable):
1.
The proposed site for the temporary use or structure is adequate in size and shape to accommodate the temporary use;
2.
The proposed site is adequately served by streets, water, power, sanitary sewer and any other necessary infrastructure of sufficient capacity to accommodate the demand that the temporary use may reasonably be expected to generate;
3.
Adequate parking to accommodate vehicular traffic to be generated by such use will be available either on-site or at alternate locations; and
4.
The operation of the requested use at the location proposed and within the time period specified will not jeopardize, endanger or otherwise constitute a menace to the public health, safety or general welfare.
5.
The proposed temporary structure and/or use is needed to restore the property to an economically or structurally viable use.
d.
Conditions of approval. In approving a temporary use permit, the Staff may impose conditions, including but not limited to control of nuisance factors (e.g., glare, noise, smoke, dust), provision of security and safety measures, notice of the temporary change in use to the County for property tax purposes, and limitations on hours of operation, storage and parking, provided that such conditions are necessary to:
1.
Achieve the general purposes of this Section and the specific purposes of the zoning district in which the temporary use will be located, or to be consistent with the Comprehensive Plan;
2.
Protect the public health, safety and general welfare; or
3.
Ensure operation and maintenance of the temporary use in a manner compatible with existing uses on adjoining properties and in the surrounding area.
e.
Time limits on permits. Following the declaration of a local emergency, temporary
use permits may be issued with an effective period of up to one (1) year from the
date of issuance. The Town Administrator may, in his or her sole discretion, have
the authority to extend a temporary use permit to a date certain if the Administrator
finds that circumstances exist that would make termination of the permit unduly prejudicial
to the holder of the permit, and that those circumstances are beyond the control of
the permit holder. Any request for an extension must be accompanied by the notice
requirements set forth in Section 16-10-60(2)(b)2., above. If, at any time while the permit is active, substantial evidence
contradicting one (1) or more of the required findings comes to the attention of the
Town Administrator, then the temporary use permit shall be revoked.
Where a recreational vehicle, mobile or manufactured home or other structure is temporarily
authorized for residential use it must be removed from the property no later than
thirty (30) days after the certificate of occupancy or a certificate of completion
is issued for the new or rehabilitated residence or upon expiration of the temporary
use permit, whichever occurs first. If the permit holder fails to remove any temporary
structure following expiration of the permit, the Town may remove the temporary structure
at the permit holder's expense. Likewise, where the approved temporary use involves
the temporary occupancy of a permanent structure that is not otherwise suitable for
habitation, the occupants must cease the temporary occupancy of the structure no later
than thirty (30) days after a certificate of occupancy is issued for the residential
structure on the property. The Town shall be responsible for notifying the Boulder
County Sheriff's Office and the Lyons Fire Protection District whenever an approved
temporary use involves the occupancy of a nonresidential structure (e.g. a garage)
or of a temporary structure.
f.
No vesting/zoning change. Issuance of a temporary use permit under this provision shall not create a vested property right, nor shall the issuance of a temporary use permit constitute a rezoning.
g.
Unlawful acts. It shall be unlawful for any person to:
1.
Continue or maintain a temporary use not otherwise allowed in the applicable zone district after the period of time set forth in this Section or in any approval issued by the Town Administrator;
2.
Fail to cease occupying or fail to remove a temporary structure from the property as required by Subparagraph e. above; or
3.
Otherwise use the property in violation of this Chapter.
h.
Appeals. The final administrative determination of the Staff may be appealed to the Board of Trustees. The decision of the Board of Trustees may be appealed to the District Court pursuant to Colorado Rules of Civil Procedure Rule 106(a)(4).

This provision for temporary uses and structures is intended only to accommodate the need for special exceptions to the zoning regulations and other applicable provisions of this Code during or resulting from officially declared local disasters or emergencies pursuant to Section 24-33.5-709, C.R.S., to provide immediate temporary relief from the direct and indirect damage to land, structures, businesses and supporting infra-structure. The principal purpose is to mitigate the loss of use and promote the rapid restoration of beneficial economic use of property that has suffered direct or indirect damage, including economic damage, due to flood, fire or other natural or manmade disaster. This Section authorizes the Town Administrator to issue permits in any zone for the temporary use of property that will aid in the immediate restoration of an area adversely impacted by a major disaster. The authorization of temporary uses and structures under this Section is intended to promote the recovery of damaged land and structures, accommodating necessary short-term transitional economic uses not otherwise provided for within the underlying zoning, to aid in the eventual restoration of permanent beneficial use consistent with the underlying zoning or proposed site specific master plan that advances the goals and objectives of the Comprehensive Plan. The Town Administrator shall have the authority to administer the provisions of this Section temporarily waiving or modifying provisions of this Code concerning building permits, demolition permits and restrictions on the use, development or occupancy of private property, provided that such action, in the opinion of the Town Administrator, is reasonably justifiable for the protection of life and property, mitigation of hazardous conditions, avoidance of undue displacement of households or businesses or prompt restoration of public infrastructure.
(1)
Critical facilities. Any police, fire, emergency medical, emergency communications facility or other critical municipal or public facility that may aid in the immediate restoration of the area may be permitted in any zone for a period not to exceed two (2) years from date of declaration of emergency.
(2)
Required findings. Other temporary uses: Temporary use permits may be issued in any zone, with conditions, as necessary, provided that written findings are made establishing a factual basis that the proposed temporary use: 1) will not be detrimental to the immediate neighborhood; 2) will not adversely affect the Comprehensive General Plan or any applicable specific plan; and 3) will contribute in a positive way to the reconstruction and recovery of areas adversely impacted by the disaster.
a.
Applicability. All applicants shall show a clear and immediate need for accommodation under this provision due to the direct or indirect damage to land, structures or business operations resulting from any officially declared disaster or emergency. All temporary uses and structures shall obtain a temporary use permit pursuant to the procedures set forth in this Section.
b.
Procedures for approval of temporary uses and structures. The procedure for an application for a temporary use or structure shall be as follows:
1.
Step 1: Pre-Application Conference. A pre-application conference is required for temporary use or structure applications under this provision. The applicant shall provide a written statement of intent that identifies the need for accommodation under this provision. Where the proposed temporary use does not conform to the underlying zoning, it shall be the applicant's responsibility to provide a written explanation of the beneficial nature of the requested temporary use as a temporary and transitional means to return to a conforming use. This may include a plan to re-zone the property in response to the changed circumstances resulting from the disaster to accommodate a use that will advance the goals and objectives of the Comprehensive Plan. The applicant shall establish the necessary connection between the temporary use as a bridge to the establishment of a permanent use.
2.
Step 2: Notice to Adjacent Property Owners of Application. The site shall be posted with a notice of the application provided by the Town for a period of at least seven (7) days before approval and issuance of a temporary use permit. Staff may also require written notice to be mailed to adjacent property owners. If so, the applicant shall provide the Town Clerk with one (1) set of stamped, addressed, certified (return receipt requested) envelopes. The envelopes shall have the Town's address as the return address and the envelopes shall be addressed to the surrounding property owners within three hundred (300) feet of the property and to any referral agencies identified by the Staff.
3.
Step 3: Staff Review and Action. Within thirty (30) days from the date a complete application is submitted and notice is posted, the Staff shall review the application according to the standards set forth in this Section and shall make a final decision to approve, approve with conditions or deny the application.
c.
Standards for review. The Staff shall review an application for a temporary use or structure and evaluate it for compliance with the following standards (as applicable):
1.
The proposed site for the temporary use or structure is adequate in size and shape to accommodate the temporary use;
2.
The proposed site is adequately served by streets, water, power, sanitary sewer and any other necessary infrastructure of sufficient capacity to accommodate the demand that the temporary use may reasonably be expected to generate;
3.
Adequate parking to accommodate vehicular traffic to be generated by such use will be available either on-site or at alternate locations; and
4.
The operation of the requested use at the location proposed and within the time period specified will not jeopardize, endanger or otherwise constitute a menace to the public health, safety or general welfare.
5.
The proposed temporary structure and/or use is needed to restore the property to an economically or structurally viable use.
d.
Conditions of approval. In approving a temporary use permit, the Staff may impose conditions, including but not limited to control of nuisance factors (e.g., glare, noise, smoke, dust), provision of security and safety measures, notice of the temporary change in use to the County for property tax purposes, and limitations on hours of operation, storage and parking, provided that such conditions are necessary to:
1.
Achieve the general purposes of this Section and the specific purposes of the zoning district in which the temporary use will be located, or to be consistent with the Comprehensive Plan;
2.
Protect the public health, safety and general welfare; or
3.
Ensure operation and maintenance of the temporary use in a manner compatible with existing uses on adjoining properties and in the surrounding area.
e.
Time limits on permits. Following the declaration of a local emergency, temporary
use permits may be issued with an effective period of up to one (1) year from the
date of issuance. The Town Administrator may, in his or her sole discretion, have
the authority to extend a temporary use permit to a date certain if the Administrator
finds that circumstances exist that would make termination of the permit unduly prejudicial
to the holder of the permit, and that those circumstances are beyond the control of
the permit holder. Any request for an extension must be accompanied by the notice
requirements set forth in Section 16-10-60(2)(b)2., above. If, at any time while the permit is active, substantial evidence
contradicting one (1) or more of the required findings comes to the attention of the
Town Administrator, then the temporary use permit shall be revoked.
Where a recreational vehicle, mobile or manufactured home or other structure is temporarily
authorized for residential use it must be removed from the property no later than
thirty (30) days after the certificate of occupancy or a certificate of completion
is issued for the new or rehabilitated residence or upon expiration of the temporary
use permit, whichever occurs first. If the permit holder fails to remove any temporary
structure following expiration of the permit, the Town may remove the temporary structure
at the permit holder's expense. Likewise, where the approved temporary use involves
the temporary occupancy of a permanent structure that is not otherwise suitable for
habitation, the occupants must cease the temporary occupancy of the structure no later
than thirty (30) days after a certificate of occupancy is issued for the residential
structure on the property. The Town shall be responsible for notifying the Boulder
County Sheriff's Office and the Lyons Fire Protection District whenever an approved
temporary use involves the occupancy of a nonresidential structure (e.g. a garage)
or of a temporary structure.
f.
No vesting/zoning change. Issuance of a temporary use permit under this provision shall not create a vested property right, nor shall the issuance of a temporary use permit constitute a rezoning.
g.
Unlawful acts. It shall be unlawful for any person to:
1.
Continue or maintain a temporary use not otherwise allowed in the applicable zone district after the period of time set forth in this Section or in any approval issued by the Town Administrator;
2.
Fail to cease occupying or fail to remove a temporary structure from the property as required by Subparagraph e. above; or
3.
Otherwise use the property in violation of this Chapter.
h.
Appeals. The final administrative determination of the Staff may be appealed to the Board of Trustees. The decision of the Board of Trustees may be appealed to the District Court pursuant to Colorado Rules of Civil Procedure Rule 106(a)(4).
