15.50 - Article VI - Subsection III

Section 260: Standards for Hazard Areas

260.1 Intent

The intent of this Section is to protect all uses, Town residents and their property, through identification and requirement of appropriate construction activity in areas where natural hazards exist so the development is sufficiently engineered to not become and/or present a hazard.

260.2 Other Regulations

This Section applies along with all other Town and State land use regulations.  If a provision of any other land use regulation conflicts with this Section, the most restrictive shall apply.

260.3 Description of Hazard Areas

Hazard areas regulated by this Section include all areas that are or may become hazardous due to environmental conditions.  Hazards include but are not limited to wildfire, avalanche, landslide, rock fall, floodway and/or plain, mud flow and debris fan, unstable or potentially-unstable and/or very steep slopes, seismic effects, radioactivity, ground-subsidence, and expansive soil and rock.

260.4 Restrictions on Development

Development proposed within an area that is or has the potential to manifest into a natural hazard may be disallowed if the development is not designed and built in a manner to adequately mitigate the identified hazard or the hazard that could result in such area if the development feature is not properly engineered.  Hazard areas and hazard conditions posed by the features of a development proposal should be identified as early in the development review process as possible.  At the earliest possible point when information on the development is available the administrators will consult sources of information such as but not limited to the hazard map(s) to help determine if hazards and/or hazardous conditions will result or exist.  As soon as reasonably practicable the administrators will discuss potential hazard areas and hazard issues with the applicant.  A strategy to mitigate all identified hazards and or conditions that may result from features of the development shall be determined and agreed upon with the administrators prior to the first public hearing on the project or before a building permit is issued.  Appropriate development agreements shall be drawn up for mitigation activities as necessary.

260.5 Classification of Hazards

For purposes of administration hazard areas can be defined using all reasonable and objective sources of information for the differing types of hazards and/or conditions.  Hazards are valid only in areas where it can be objectively established that the identified hazard exists.

260.6 Post Approval Requirements

No variances are allowed from the provisions of this section of the LUC.

Section 261: Standards for Floodplains and Floodways

261.1 Intent

The intent of this Section is to ensure that all development, including but not limited to, roads, bridges, subdivisions, and gravel pits, do not impact or become impacted by development in a floodplain and/or floodway and development is in compliance with the National Flood Insurance Program.  Flood hazard areas of the town are subject to periodic inundation which may result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare.  These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities, and, when inadequately anchored, damage uses in other areas.  Uses that are inadequately flood-proofed, elevated, or otherwise protected from flood damage also contribute to the flood loss.

261.2 Methods of Reducing Flood Impact

In order to accomplish the purpose of managing the floodplain as established under the National Flood Insurance Program and those Town policies for development in the floodplain, these standards include methods and provisions for:

  • Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities;
  • Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
  • Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel flood waters;
  • Controlling the filling, grading, dredging, and other development which may increase flood damage; and,
  • Preventing or regulating the construction of flood barriers that will unnaturally divert flood waters or which may increase flood hazards in other areas.

261.3 Definitions

Unless specifically defined below, words or phrases used in this Section shall be interpreted so as to give them the meaning used in common language and to give this Section the most reasonable application.

"Area of special flood hazard" means the land in the floodplain within a community subject to a one percent (1%) or greater chance of flooding in any given year.

"Base flood" means the flood having a one percent (1%) chance of being equaled or exceeded in any given year.

"Development" means any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations located within the area of special flood hazard.

"Flood" or "flooding" means a general and temporary condition of partial or complete inundation of normally dry land areas from the overflow of inland or tidal waters and/or

  • The unusual and rapid accumulation or runoff of surface waters from any source.
  • "Flood Hazard Boundary Map 11 (FHBM) means the official map issued by the Federal Insurance Administration where the areas of special flood hazard have been designated Zone A.

"Habitable floor" means any floor usable for living purposes, which includes working, sleeping, eating, cooking or recreation, or a combination thereof.  A floor used only for storage purposes is not a "habitable floor.”

"Mobile Home" means a structure that is transportable in one or more sections, built on a permanent chassis, and designed to be used with or without a permanent foundation when connected to the required utilities.  It does not include recreational vehicles or travel trailers.

Structure means a walled and roofed building or mobile home that is principally above ground.

"Substantial improvement" means any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds 50 percent (50%) of the market value of the structure either before the improvement or repair is started, or if the structure has been damaged and is being restored, before the damage occurred.  For the purposes of this definition "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure.  The term does not, however, include any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions, or any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.

261.4 Lands to Which this Section Applies

This Section shall apply to all areas of special flood hazards (mapped floodplains) and all floodways, including obvious dry arroyos, within the jurisdiction of Town of Rangely.  The areas of special flood hazard identified by the Federal Emergency Management Agency in a scientific and engineering report entitled “The Flood Insurance Study” for the Town of Rangely, effective September 28, 1990, with an accompanying flood insurance rate map is adopted by reference and declared to be a part of this Section and is on file at the Town Hall, Rangely, Colorado.

261.5 Compliance

No structure or land development feature (road, pond, etc) or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of these standards and other applicable regulations.

261.6 Abrogation and Greater Restrictions

These standards are not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions.  However, where these standards and another resolution, ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.

261.7 Interpretation

In the interpretation and application of these standards, all provisions shall be:

  • Considered as minimum requirements;
  • Liberally construed in favor of the governing body, and;
  • Deemed neither to limit nor repeal any other powers granted under state statutes.

261.8 Warning and Disclaimer of Liability

The degree of flood protection required by these standards is considered reasonable for regulatory purposes and is based on scientific and engineering considerations.  Larger floods can and will occur on rare occasions.  Flood heights may be increased by man-made or natural causes.  These standards do not imply that land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages.  These standards shall not create liability on the part of the Town.

261.9 Establishment of Development Permit

For purposes of development in the floodplain an approval shall be obtained before construction or development begins within any area of special flood hazard as established.  Application for an approval shall be made on forms furnished by the Town and approval is subject to the information and submittal requirements of this LUC as applicable.  The receipt of an approval under this LUC is regarded as the appropriate permit for compliance with this Section.  Specifically, the following information is required:

  • Elevation in relation to mean sea level, of the lowest floor (including basement) of all structures;
  • Elevation in relation to mean sea level to which any structure has been flood-proofed;
  • Certification by a registered professional engineer or architect that the flood-proofing methods for any non -residential structure meet the flood-proofing criteria and,
  • Description (and engineering) providing information of the extent to which any watercourse will be altered or relocated as a result of proposed development and evidence that the development has mitigated potential impacts to surrounding uses and property.

261.10 General Standards

In all areas of special flood hazards the following standards shall apply:

261.10.1 Anchoring

  • All new construction and substantial improvements shall be anchored to prevent flotation, collapse, or lateral movement of the structure.

261.11.2 Nonresidential Construction

New construction and substantial improvement of any commercial, industrial or other nonresidential structure shall have either the lowest floor, including basement, elevated to the level of the base flood elevation; or, together with attendant utility and sanitary facilities, shall:

  • be flood-proofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water;
  • have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and be certified by a registered professional engineer or architect that the standards of this Subsection are satisfied.

261.11.3 Manufactured Homes

Manufactured homes shall be anchored in accordance with this standard.  All manufactured homes or those to be substantially improved shall conform to the following requirement:
A manufactured home that is newly installed or has incurred "substantial damage" as the result of a flood, shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated to or above the base flood elevation and shall be securely anchored to an adequately anchored foundation system to resist floatation, collapse and lateral movement.

261.12 Floodway

Development located within areas that are or could be designated as floodways are an extreme risk due to the velocity of flood waters which carry debris, potential projectiles and erosion potential.  The following provision shall apply to all areas that could be considered floodways and flash flood channels:

It is prohibited to encroach, fill, construct new or substantial improvements, and other development unless certification by a registered professional engineer is provided demonstrating that encroachments (as defined by any of the above) shall not result in any increase in flood levels during the occurrence of the base flood discharge and/or that the development will not present undue hazard to surrounding uses and/or properties.

Section 262: Standards for Fire Protection and Emergency Medical Service

262.1 Intent

The intent of this Section is to establish minimum regulations consistent with nationally recognized good practice for the safeguarding of life and property from the effects of fire, wildfire, and to provide for an orderly response to emergencies.  Regulations in this Section of this Code are intended to mitigate the risk to life and structures from intrusion of fire, from wildland fire exposures, fire exposures from adjacent structures and to mitigate structure fires from spreading to wildland fuels.  The extent of this regulation is intended to be tiered commensurate with the relative level of hazard present.  The unrestricted use of property in wild-land fire hazard areas is a potential threat to life and property from fire and resulting erosion.  Safeguards to prevent the occurrence of fires and to provide adequate fire-protection facilities to control the spread of fire throughout the Town and into the County and particularly in urban-wildland interface areas, shall be in accordance with this LUC.  This standard is intended to supplement the Fire Districts’ jurisdictions to provide for consistency in application and to mitigate the fire and life-safety hazards in the Town.

262.2 Level of Service and Access

Proximity to Fire/EMS Station:  Development shall provide access roads capable of supporting emergency equipment year-round.  Compliance with this part shall be determined in conjunction with the Standards for Transportation and Location Systems in the Conditions of the Roads/Streets section of that standard.  

At a minimum, access shall consist of all-weather roads with a minimum width of 20 feet and a clear height of 13 feet 6 inches and shall be designed to accommodate the loads and turning radii for fire apparatus.  They should have a gradient negotiable by the specific fire apparatus normally used at that location within the jurisdiction.  Dead-end roads in excess of 150 feet (45,720 mm) in length shall be provided with turnarounds, as applicable, as determined by the Fire District of jurisdiction.  All-weather road surface shall be any surface material acceptable to the administrators and fire districts that will normally allow the passage of emergency service vehicles typically used to respond to that location within the jurisdiction.  The gradient for access roads and driveways shall not exceed the maximum approved by the Town and Fire Districts, generally not in excess of 10%.

Access to all water sources, required by the Fire District and/or this LUC shall be unobstructed at all times.  The administrators and emergency equipment shall not be deterred or hindered from gaining immediate access to water source equipment, fire-protection equipment or hydrants

262.3 Location Systems

Marking of roads with approved signs or other approved notices shall be provided and maintained for access roads and driveways to identify such roads and prohibit the obstruction thereof or both.  All road identification signs and supports shall be of noncombustible materials.  Signs shall in general have 4-inch-high reflective letters with ½-inch stroke on a contrasting 6-inch-high sign.  Road identification signage shall in general be mounted at a height of 7 feet (2134 mm) from the road surface to the bottom of the sign.  Fire-Protection Equipment and fire hydrants shall be clearly marked in a manner approved by the administrators and Fire District.  Existing roads and fire protection equipment shall be provided with address markers as noted above.

All buildings shall have a permanently posted address, which shall be placed in a visible location such as but not limited to driveway entrance, home front, garage so that it is visible from both directions of travel along the road.  In all cases, the address shall be posted at the beginning of construction and shall be maintained thereafter, and the address shall be visible and legible from the road on which the address is located.  Address signs along one-way roads shall be visible from both directions.

Where multiple addresses are required at a single driveway, they shall be mounted on a single post, and additional signs shall be posted at locations where driveways divide.  Where a roadway provides access solely to a single commercial or industrial business, the address sign shall be placed at the nearest road intersection providing access to that site.

Identification of water sites, draft sites, hydrants and fire-protection equipment and hydrants shall be clearly identified in a manner approved by the administrators to identify location and to prevent obstruction by parking and other obstructions.

262.4 Central Water Distribution Supply

All development that utilizes a central water system shall conform to the requirements of the Fire District in which it is located.  In general, where a central water system is provided, fire hydrants shall be provided in all developments and shall be separated by no more than 600 feet.  No dwelling shall be more than 300 feet from the nearest hydrant.  Fire-fighting water sources for the proposed development should meet the requirements set forth in the National Fire Protection Association, National Fire Code, Standard 1231 'Standard On Water Supplies For Suburban And Rural Fire Fighting' or the specific fire regulations agreed upon with the Fire Protection District of jurisdiction.

262.5 Other Standards

Individual fire protection districts may have adopted or may use higher standards than those specified in this Section.  If so, those higher standards will apply.

262.6 Submittal Requirements

When required by the administrators and/or fire districts, applicants shall provide a plan with a narrative describing the fire protection situation.  The plan shall include a vicinity map showing the location of fire stations, route used for calculating the proximity-to-fire-station criteria, information on road design and provisions for complying with this standard.

Section 263: Standards for Airport Impact Areas

263.1 Intent

The intent of this Section is to ensure that new construction does not impact the area around and/or the navigatable air space of the airport within the Town of Rangely.

263.2 Standard

All development that is within the airport impact area as defined in the most recent airport plan categorizing the airspace and impact area shall mitigate any potential impact and comply with Federal Aviation Regulation Part 77-Objects Affecting Navigable Airspace and any others that may apply including FAA form 7460 (reporting of structures above 1:100 foot relationship from the centerline of the main runway) or over 200 feet if further than 20,000 feet.  In addition the following provisions shall apply:

263.2.1 Light sources shall be controlled or hooded so that light is directed away from the flight patterns around the airport and from any adjoining residentially zoned property or public streets.

263.2.2 No activity shall be permitted that creates any off-site electrical disturbance (especially radio transmissions to or from any aircraft).

263.2.3 No emission of air contaminants in the form of smoke or visual deterrent from any source within the boundaries of any lot or tract shall be allowed if it has the potential to impact the navigable airspace around an airport.

263.2.4 No material change shall be made in the use of land and no structure or tree shall be erected, planted, altered or otherwise established that would result in an obstruction into the airport hazard area of the Town of Rangely airport.  This regulation shall not be construed to require the removal, lowering or other changes of any structure or tree not conforming to this regulation as of its adoption date.

Section 264: Standards for Oil and Gas Operations
