Myrtle Creek City Zoning Code

Twelve to less than 16 percent slope: no more than 40 percent of such areas shall be developed and/or regraded or stripped of vegetation.

Sixteen to 25 percent slope: no more than 30 percent of such areas shall be developed and/or regraded or stripped of vegetation, with the exception that no more than 20 percent of such areas may be disturbed in the case of poor soil suitability (i.e., Nonpareil No. 5).

More than 25 percent slope: not more than 15 percent of such areas shall be developed and/or regraded or stripped of vegetation, with the exception that no more than five percent of such areas may be disturbed in the case of very poor soil suitability (i.e., Nonpareil No. 6).

All erodible slopes shall be protected in accordance with the control standards contained in MCMC § 18.160.070.

All such areas shall remain as permanent open space. No uses or improvements other than those permitted herein shall be permitted in any erosion hazard area or any area consisting of bluff as defined by this title.

In the erosion hazard area associated with bluffs, any nonstructural recreational use is permitted, including pedestrian accessways.

Erosion hazard areas may be used to provide vehicular access to nonhazard areas. In this event, an environmental assessment (or site investigation report) shall provide the basis for location of such access. Minimum damage to the area shall be the guide in location of the access.

All erodible slopes shall be protected in accordance with the control standards contained in MCMC § 18.160.070.

At least 98 percent of all ravines shall remain in permanent open space. At least 80 percent of all ravine buffers shall remain in permanent open space. No uses or improvements other than those permitted herein shall be permitted in any area consisting of ravines or ravine buffers as defined by this title.

Ravines shall not be the site of any land use or development, with the exception that access to other areas may be provided in ravine areas. In this event, an environmental assessment (or site investigation report) shall provide the basis for location of such access. Minimum damage to the area shall be the guide in location of the access. The protected areas of ravine buffers shall be used only for passive recreation.

All erodible slopes shall be protected in accordance with the control standards contained in MCMC § 18.160.070.

The determination of floodplain boundaries and the standards for flood hazard area protection are contained in the regulations for the special district/flood hazard area. Whenever any land located in a stream channel or body of water is disturbed, a soil erosion or sedimentation control plan shall be submitted in accordance with MCMC § 18.160.070.

Located within areas of special flood hazard are areas designated as floodways. In accordance with the natural resources element of the comprehensive plan, the floodway shall be designated as open space, forming a greenway, and is to be incorporated in the recreation/open space system proposal. Rights-of-way or easements, whenever feasible, shall be provided at the time of development on all properties located in the floodway as shown on the open space (greenway) proposal.

Greenways are linear green belts linking residential areas with other open space areas. These greenways may contain bicycle paths, footpaths and bridle paths. Connecting greenways between residences and recreational areas is encouraged. Maintenance is limited to minimum removal and avoidance of hazards, nuisances, or unhealthy conditions.

The time of concentration of stormwater flows remains unchanged or is lengthened.

Stormwater and ground water storage capacity is unchanged or increased.

Vegetation is replanted.

The resultant new drainageway has less velocity than preexisted or reduces streambank erosion through the provision of erosion control measures.

SESC Plan. In order to prevent both soil erosion and sedimentation, a soil erosion and sedimentation control plan shall be required as part of an application for development whenever any land located in a stream, stream channel or body of water is disturbed and whenever a development will involve any clearing, grading, transporting, or other form of disturbing land by the removal of earth, including the mining of minerals, sand, and gravel; provided, that any one of the following descriptions applies to said movement of land:

Definitions for the purpose of this section are:

Erosion Control Measures. All measures necessary to minimize soil erosion and to control sedimentation in the disturbed land area shall be provided, which includes obtaining any appropriate state and/or federal erosion control permits. Specifically, the following protection shall be provided for all disturbed areas: Minimize velocities of water runoff, maximize protection of disturbed areas from stormwater runoff, and retain sedimentation within the development site as early as possible following disturbances. A list of major problem areas for erosion and sedimentation control follows. For each one, the purpose(s) of requiring control is described. Soil erosion and sedimentation control measures for all such areas shall be provided with a view toward achieving the specific purpose listed below for which a control plan is required.
