18.100.080 Special district overlay – Erosion hazards near sensitive water bodies.

(1) The purpose of the erosion hazards near sensitive water bodies special overlay district is to provide a means to designate sloped areas posing erosion hazards which drain directly to lakes or streams of high resource value which are particularly sensitive to the impacts of increased erosion and the resulting sediment loads from development.

(2) The following development standards shall be applied in addition to all applicable requirements of Chapter 18.65 CMC to development proposals located within erosion hazards near a sensitive water bodies district overlay:

(a) A no-disturbance area shall be established on the sloped portion of the special district overlay to prevent damage from erosion. Land clearing or development shall not occur in the no-disturbance area, except for the clearing activities listed in subsection (2)(a)(i) of this section. Clearing activities listed in subsection (2)(a)(i) of this section shall only be permitted if they meet the requirements of subsection (2)(a)(ii) of this section.

(i) Clearing activities may be permitted as follows:

(A) For the construction of single-family residences on pre-existing separate lots;

(B) For the construction of utility corridors to service existing development along existing rights-of-way including any vacated portions of otherwise contiguous rights-of-way;

(C) For the construction of roads providing sole access to buildable property and associated utility facilities within those roadways; or

(D) For the construction of development within an isolated no-disturbance area of two acres or less in size. The isolated no-disturbance area is either geologically separated from other no-disturbance areas or lies completely within a separate drainage sub-basin and is, therefore, hydrologically isolated from the rest of the no-disturbance area.

(ii) The clearing activities listed in subsection (2)(a)(i) of this section may be permitted only if the following requirements are met:

(A) A report which meets the requirements of CMC 18.65.120 shall show that the clearing activities will not subject the area to risk of landslide or erosion and that the purpose of the no-disturbance area is not compromised in any way;

(B) The clearing activities shall be mitigated, monitored and bonded consistent with the mitigation requirements applicable to sensitive areas regulated in Chapter 18.65 CMC;

(C) The clearing activities are limited to the minimal area and duration necessary for construction; and

(D) The clearing activities are consistent with Chapter 18.65 CMC.

(3) The following conditions shall apply to the wetland or along the main channel of the stream riparian zone containing the heron rookery (tributary streams are excluded).

(a) The upslope boundary of the no-disturbance area lies at the first obvious break in slope from the upland plateau over onto the steep valley walls. The downslope boundary of this zone includes those areas designated as erosion or landslide hazard areas pursuant to CMC 18.65.220 and 18.65.280. The sensitive areas folio indicates the general location of these hazard areas, but it cannot be used to specify the areas’ precise boundaries. Maps of the approximate boundaries of these no-disturbance zones shall be available at the Department. Single-family or multifamily residential density from the no-disturbance area may be reallocated onto any buildable portion of the site pursuant to CMC 18.30.080, or transferred to other sites pursuant to Chapter 18.95 CMC.

(b) New development proposals for sites which drained predeveloped runoff to the no-disturbance zone shall evaluate the suitability of on-site soils for infiltration. All runoff from newly constructed impervious surfaces shall be retained on-site unless this requirement precludes the ability to meet minimum density requirements in Chapter 18.30 CMC. When minimum density cannot be met, runoff shall be retained on-site as follows:

(i) Infiltration of all site runoff shall be required in granular soils as defined in the City of Covington surface water design manual;

(ii) Infiltration of downspouts shall be required in granular soils and in soil conditions defined as allowable in the surface water design manual when feasible to fit the required trench lengths on-site;

(iii) When infiltration of downspouts is not feasible, downspout dispersion trenches shall be required when minimum flow paths defined in the surface water design manual can be met on-site or into adjacent open space; and

(iv) When dispersion of downspouts is not feasible, downspouts shall be connected to the drainage system via perforated pipe.

(c) For the portions of proposed subdivisions, short subdivisions and binding site plans that cannot infiltrate runoff up to the 100-year peak flow, at least 25 percent shall remain undisturbed and set aside in an open space tract consistent with CMC 18.65.150 through 18.65.180.

(d) For the portions of all development proposals that cannot infiltrate runoff up to the 100-year peak flow, no more than 35 percent of the gross site area shall be covered by impervious surfaces. For new subdivisions and short subdivisions, maximum lot coverage should be specified for subsequent residential building permits on individual lots.

(e) If the application of this section would deny all reasonable use of property, the applicant may apply for a reasonable use exception pursuant to CMC 18.65.070(2).

(f) The Director may modify the property specific development standards required by subsections (3)(a) through (e) of this section, when a development proposal complies with the following:

(i) The proposed development is subject to public/private partnerships such as an approved community block grant or other such water quality program designed to improve water quality in the basin;

(ii) The proposed development is designated by City of Covington as a demonstration project designed to implement best management practices and state of the art technology that assures the greatest possible improvement to water quality; and

(iii) A site-specific study is conducted by the applicant and approved by the Director, which demonstrates that the proposed development substantially increases water quality by showing the following:

(A) Water quality on-site is improved;

(B) The development project will not subject downstream channels to increased risk of landslide or erosion;

(C) The development project will not subject the nearest sensitive water body to additional erosion hazards; and

(D) The project is consistent with subsections (3)(f)(i) and (ii) of this section, and provides predictable improvements to water quality. (Ord. 42-02 § 2 (21A.38.200))

18.100.090 Special district overlay – Urban stream protection area.

(1) The purpose of the urban stream protection area special district overlay is to provide a means to designate areas with substantial fisheries resources that have severe flooding and stream damage problems from high storm water volumes. This district overlay limits land coverage along significant urban stream corridors to reduce storm water volumes and the costs associated with flooding problems and loss of salmon resources.

(2) The following development standards shall be applied to development proposals on R-1 zoned parcels located within an urban stream protection area district overlay:

(a) Clearing is limited to and development shall be clustered on 30 percent of the site. Parcels adjacent to streams or wetlands shall place structures as far as feasible from streams and wetlands. For binding site plans, subdivisions and short subdivisions, the remaining 70 percent of the site shall be placed in a contiguous permanent open-space tract retaining the native vegetation. For individual lots, the remaining 70 percent of the parcel shall retain the native vegetation and be placed in a County-approved conservation easement, or notice shall be placed on the title of the lot. The notice shall be approved by the City of Covington and filed with the Records and Elections Division. The notice shall inform the public of the presence and location of an urban stream protection area on the property and that limitations on actions in or affecting the corridor exist;

(b) Where existing clearing has already exceeded 30 percent of the gross acreage of the site, reforestation according to a County-approved plan shall be provided to restore native forested cover to 70 percent of the site;

(c) The maximum impervious surface area shall be eight percent of the gross acreage of the site. Proposed short subdivisions, subdivisions, and binding site plans shall record the distribution of allowable impervious area among individual parcels on the face of the plat. Impervious surface of roads shall not be counted towards the allowable impervious area. This condition may be modified by the Director only as necessary to accommodate unusual site access conditions;

(d) Keeping or grazing of livestock shall be prohibited; and

(e) No road crossings of streams defined in CMC 18.20.1240 shall be allowed. Crossing of streams by utilities shall be limited to existing road or utility rights-of-way unless no feasible alternative exists. (Ord. 42-02 § 2 (21A.38.220))

18.100.100 Special district overlay – Significant trees.

Repealed by Ord. 04-08. (Ord. 42-02 § 2 (21A.38.230))

18.100.110 Special district overlay – Floodplain density.

(1) The purpose of the floodplain density special district overlay is to provide a means to designate areas that cannot accommodate additional density due to severe flooding problems. This district overlay limits development in sensitive areas to reduce potential future flooding.

(2) The following development standards shall be applied to all development proposals on RA-5 zoned parcels located within a floodplain density special district overlay:

(a) Density is limited to one home per 10 acres for any property that is located within a sensitive area; and

(b) All development shall be clustered outside of the identified sensitive areas, unless the entire parcel is a mapped sensitive area. (Ord. 42-02 § 2 (21A.38.240))
