Dams: The State Engineer regulates dam safety for embankments greater than 10 feet in height, or water surface area greater than 20 acres, or retains greater than 100 acre feet plus water, CRS37-87-105 as amended. While the State Engineer's office does not have funding to allow examination of small impoundments under 10 feet, a citizen who believes that a dam is unsafe can request an inspection by the State Engineer under Section 37-87-109C.R.S(1973). If the structure is not found to be unsafe, then the person requesting the inspection must pay the expenses incurred by the State Engineer.
Hazardous Materials: The Jefferson County Office of Emergency & Disaster Services has additional information about the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and the Federal Superfund Amendment and Reauthorization Act of 1986 (SARA), 42 USC 9601 et.seq. and their application to Jefferson County.
Jefferson County Recycling & Household Hazardous Waste Program: The Jefferson County Board of Commissioners in April, 1987, appointed an advisory group to work with the County Solid Waste Coordinator to address recycling and household hazardous waste. For additional information, contact the Solid Waste Coordinator at the Jefferson County Planning Department.
Landfills/Methane Gas: Jefferson County Health and Environmental Services has mapped all known landfills and methane readings in the County. This information is available at the Health and Environmental Services office and includes information on the geology, site physiology and landfill history.
Undesirable Plants: Defined in the Colorado Weed Management Act are the following noxious species: leafy spurge (Euphorbia esula); the knapweed plants commonly known as diffuse, Russian, and spotted knapweeds (Centaurea diffusa, Centaurea repens, and Centaurea maculosa).
The Board of County Commissioners may designate additional undesirable plants within its jurisdiction after a public hearing with thirty days prior notice to the public. Source: CRS 35-5.5-108
Please review the following maps which were adopted as part of this Plan:
The projections of housing units were computed in the following manner.
1. The North Mountains area was divided into traffic zones.
2. For each traffic zone the amount of acreage for each slope category was determined; 0-30%, 30-40%, 40+%.
3. The amount of acreage for each slope category was reduced by 20% to account for driveways, roads, etc.
4. The reduced slope/acreage was divided by the acreage per housing unit for each scenario: existing zoning (assumed to be 1 du/10 acres) and the Housing section policy recommendations.
5. The number of units per traffic zone were then summed.
Note: The number of future housing units assumes existing development. The Housing section recommendations for development served by public water and sanitation were not used to project traffic generation. The traffic projections are based on build-out of existing zoning, standard and excellent design housing density policies.
Well and septic: When well and septic will be used, the potential number of housing units on a site is based on the amount of acreage in each slope category and the degree of excellence of site design, i.e., compliance with other Plan polcies and Mountain Site Design Criteria. Lot size can vary depending on the site design, hydrologic study, and type of water and sanitation service provided.

Highway Capacity Improvements: Additional capacity on two-lane highways can be gained with treatments, such as: Improving sight distance, providing paved shoulders, adding a third lane for passing or climbing, and providing protected turning lanes for left and right turns at intersections. The additional capacity to be gained by these treatments depends on level of service, type of terrain, and the amount of no passing zones. Depending on the existing conditions and the proposed improvement, the additional capacity gained could range from a few percent up to approximately 50%.

Level of Service: Level of service (LOS) is used to express, numerically, the driving experience on various roads. LOS A provides relaxed travel at the speed limit without delays. LOS F would mean extreme delays, even gridlock, with speeds well below the posted limit.
A level of service definition generally describes driving experience in terms of such factors as speed and travel time, freedom to maneuver, traffic interruptions, comfort and convenience, and safety.
Six levels of service are defined for each type of facility for which analysis procedures are available. They are given letter designations, from A to F, with LOS A representing the best operating conditions and LOS F the worst.
Level of service definitions: In general, the various levels of service are defined as follows for uninterrupted flow facilities:
LOS A represents free flow. Individual users are virtually unaffected by the presence of others in the traffic stream. Freedom to select desired speeds and to maneuver within the traffic stream is extremely high. The general level of comfort and convenience provided to the motorist, passenger, or pedestrian is excellent.
LOS B is in the range of stable flow, but the presence of other users in the traffic stream begins to be noticeable. Freedom to select desired speeds is relatively unaffected, but there is a slight decline in the freedom to maneuver within the traffic stream from LOS A. The level of comfort and convenience provided is somewhat less than at LOS A, because the presence of others in the traffic stream begins to affect individual behavior.
LOS C is in the range of stable flow, but marks the beginning of the range of flow in which the operation of individual users becomes significantly affected by interaction with others in the traffic stream. The selection of speed is now affected by the presence of others, and maneuvering within the traffic stream requires substantial vigilance on the part of the user. The general level of comfort and convenience declines noticeably at this level.
LOS D represents high-density, but stable, flow. Speed and freedom to maneuver are severely restricted, and the driver or pedestrian experiences a generally poor level of comfort and convenience. Small increases in traffic flow will generally cause operational problems at this level.
LOS E represents operating conditions at or near the capacity level. All speeds are reduced to a low, but relatively uniform value. Freedom to maneuver within the traffic stream is extremely difficult, and it is generally accomplished by forcing a vehicle or pedestrian to "give way" to accommodate such maneuvers. Comfort and convenience levels are extremely poor, and driver or pedestrian frustration is generally high. Operations at this level are usually unstable, because small increases in flow or minor perturbations within the traffic stream will cause breakdowns.
LOS F is used to define forced or breakdown flow. This condition exists wherever the amount of traffic approaching a point exceeds the amount which can traverse the point. Queues form behind such locations. Operations within the queue are characterized by stop-and-go waves, and they are extremely unstable. Vehicles may progress at reasonable speeds for several hundred feet or more, then be required to stop in a cyclic fashion. LOS F is used to describe the operating conditions within the queue, as well as the point of the breakdown. It should be noted, however, that in many cases operating conditions of vehicles or pedestrians discharged from the queue may be quite good. Nevertheless, it is the point at which arrival flow exceeds discharge flow which causes the queue to form, and LOS F is an appropriate designation for such points.
These definitions are conceptual in nature, and they apply primarily to uninterrupted flow. Levels of service for interrupted flow facilities vary widely in terms of both the user's perception of service quality and the operational variables used to describe them. Each chapter of the Highway Capacity Manual contains more detailed descriptions of the levels of service as defined for each facility type.
On the following chart, the amount of traffic is expressed as Average Daily Trips (ADT), i.e., the number of trips during a 24-hour period. Peak travel times in the morning and evening can result in a lower level of service.
Maximum AADT (Average Annual Daily Traffic) Versus Level of Service for Two-lane Rural Highway Rolling Terrain
The Colorado Department of Transportation (CDOT) and the Jefferson County Highways and Transportation Department use the following definitions for terrain:
Rolling Terrain: Any combination of horizontal and vertical alignments causing heavy vehicles to reduce their speed substantially below that of passenger cars, but not causing heavy vehicles to operate at crawl speeds for any significant amount of time.
Mountainous Terrain: Any combination of horizontal and vertical alignment causing heavy vehicles to operate at crawl speeds for significant distances or at frequent intervals.
CDOT and Highways and Transportation agree that U.S. 6 and S.H. 72 are "rolling terrain". In addition, Jefferson County Department of Highways and Transportation characterizes Golden Gate Canyon and Crawford Gulch roads as "rolling terrain".
