21.40.070 Requirements.

The requirements of this section shall apply to all structures and uses in the BCWP district unless more stringent requirements are required pursuant to Chapter 21.71 HCC. The City of Homer water utility is exempt from this section.

a. Impervious Coverage.

1. Lots two and one-half acres and larger shall have a maximum total impervious coverage of 4.2 percent.

2. Lots smaller than two and one-half acres shall have a maximum total impervious coverage of 4.2 percent, except as provided in subsection (a)(3) of this section.

3. Lots smaller than two and one-half acres may be allowed impervious coverage up to 6.4 percent if (a) the owner submits a lot-specific mitigation plan for the City Planner’s approval, and (b) if approved, thereafter implements and continuously complies with the approved plan. The mitigation plan must be designed to mitigate the effect of impervious coverage on water flow and the effect of loss of vegetation created by the impervious coverage and shall comply with the following performance standards:

a. Disturbed areas shall be reseeded by August 31st.

b. Stormwater retention for the proposed new impervious surface must be provided on site.

i. The post-development stormwater discharge rate shall not exceed the pre-development peak discharge rate (PDR) for the 10-year frequency storm event, consisting of rainfall for a period of three consecutive hours at a rate of one-half inch per hour.

ii. Retention may be provided in the form of one or a combination of dry wells, rain barrels, rain gardens, foot drain retention or other method approved by the City Planner.

b. Impervious Coverage Calculations.

1. For the purpose of calculating impervious coverage on lots smaller than two and one-half acres, 50 percent of driveways and walkways may be excluded from the calculation, if constructed and maintained in accordance with a mitigation plan that addresses the entire impervious coverage proposed for the lot, submitted and approved in accordance with subsection (a)(3) of this section. Exclusion of more than 50 percent of driveways and walkways from the calculation shall require approval of the Planning Commission.

2. Except as otherwise provided in this section, parcels of land subdivided after February 25, 2003, shall be allowed a total impervious coverage of 4.2 percent including right-of-way (ROW) dedication. ROW coverage area shall be calculated as 50 percent of the total area of the dedicated ROW. The impervious coverage allowed for the subdivided parcels shall be calculated after deducting the ROW coverage from the total parcel allowance according to the following formula:

 

Formula:

(Area of parcel being subdivided) x 0.042 = Total allowed impervious coverage (TAC)

(Area of ROW dedication) x 0.5 = ROW coverage (ROW C)

(TAC) – (ROW C) = Allowed impervious coverage for remainder of parcel being subdivided

(Area of parcel being subdivided) – (Area of ROW dedication) = New parcel area

(Allowed impervious coverage for remainder) ÷ (New parcel area) x 100 = Percent impervious coverage allowed on subdivided lots.

c. Additional Requirements for Subdivisions and Lots.

1. Lots created by subdivision after February 25, 2003, shall be a minimum of four and one-half acres.

2. Applications for subdivisions, dedications, and vacations of easements and rights-of-way in the BCWP district must be approved by the Planning Commission prior to submission to the Kenai Peninsula Borough.

d. Building Setbacks. Buildings must be set back from the Bridge Creek Reservoir and from streams as provided in HCC 21.40.110 and 21.40.120.

e. Sewer Systems. Appropriate to the use of the lot, each lot shall be served by a septic or sewer system approved by the Alaska State Department of Environmental Conservation (ADEC). Stream setbacks equal to 100 feet for drain fields and subsurface discharge and 250 feet for raised septic systems are required.

f. Ongoing Construction and Timber Harvesting. All activities including, but not limited to, timber harvesting, road building, subdivision and building activities involving loss of vegetation ground cover or soil disturbance and that are in process on February 25, 2003, shall be required to obtain permits under this chapter and shall fully conform to the terms of this chapter. Activities leaving disturbed or lost vegetative ground cover, disturbed soils without revegetation or leaving slash piles will be considered in process for the purposes of this subsection, regardless of when the activity occurred.

g. Pending Subdivisions. Subdivisions that have not received final plat approval by February 25, 2003, shall obtain approval from the Planning Commission and shall be required to conform to the requirements of this chapter. [Ord. 15-23(S) § 1, 2015; Ord. 08-29, 2008].

21.40.080 Erosion and sediment control.

a. All activities within the BCWP district involving the disturbance of the existing ground cover (i.e., topsoil or vegetation or both) resulting from excavation, grading or filling or other similar activity and involving (1) any area within 500 feet of Bridge Creek Reservoir or 100 feet from any known stream or tributary or (2) an area in excess of 6,000 square feet require a conditional use permit approved by the Planning Commission. The conditional use permit must require that the activity comply with a site-specific erosion and sediment control plan prepared and signed by a certified hydrologist, professional engineer, or soil scientist whose qualifications to prepare such a plan are reviewed and approved by the Public Works Director.

b. The erosion and sediment control plan shall ensure compliance with the following requirements:

1. A drainage system shall be provided to direct all runoff from impervious coverage or the disturbed ground either into an engineered drainage system or into a natural drainage, but no runoff shall be discharged untreated directly into the Bridge Creek Reservoir, or any stream or watercourse tributary to Bridge Creek Reservoir.

2. Where open-ditch construction is used to handle drainage within the tract, a minimum of 30 feet shall be provided between any structures and the top of the bank of the defined channel of the drainage ditch.

3. When a closed system is used to handle drainage within the tract, all structures shall be a minimum of 10 feet from the closed system.

4. Natural vegetation shall remain undisturbed except as necessary to construct improvements and to eliminate hazardous conditions, in which case it must be replanted with approved materials including ground cover, shrubs and trees. Native vegetation is preferred for replanting operations, and will be used where practicable.

5. Grading must not alter the natural contours of the terrain except as necessary for building sites or to correct unsafe conditions. The locations of buildings, roads and rights-of-way must be planned to follow and conform to existing contours as nearly as possible.

6. Upon completion of earthwork, all exposed slopes and all cleared, filled, and disturbed soils shall immediately be given sufficient protection by appropriate means, such as landscaping, planting, and maintenance of vegetative cover, or temporary protective measures to prevent erosion.

7. All exposed, cleared, filled and disturbed soils shall be revegetated within the current growing season, unless required to be revegetated sooner by other provisions of this title or other law.

8. Drainage, erosion, siltation, slope failure and other adverse effects may be prevented or controlled by means other than vegetation, if approved by the Planning Commission.

9. Development activities shall not adversely impact other properties or watershed water quality by causing adverse alteration of surface water drainage, increased turbidity above natural conditions, surface water ponding, slope failure, erosion, siltation, intentional or inadvertent fill, root damage to neighboring trees, or other adverse physical impacts. The erosion and sediment control plan shall address this requirement, and the property owner and developer shall take such steps, including installation of culverts or buffers, or other methods, as necessary to comply with this requirement. [Ord. 08-29, 2008].

21.40.110 Stream buffers.

a. A stream buffer must be preserved and maintained along all perennial and intermittent streams in the BCWP district. The stream buffer must be at least 50 feet on each side of the stream measured from the top of the stream bank. Buildings and other features that require grading or construction must be set back at least 10 additional feet from the edge of the buffer. To avoid a decrease in the buffer’s effectiveness in protecting the stream the buffer shall remain in natural and undisturbed vegetation.

b. The following exceptions or intrusions into the stream buffer may be granted by conditional use permit approved by the Planning Commission:

1. Street, driveway, culvert, recreational features, intakes, utilities, bridges or other crossings; provided, that they are designed to minimize the amount of intrusion into the buffer. The aforementioned structures and improvements may run generally within the stream buffer only where no other access route is available and when their design minimizes the amount of intrusion of the stream buffer.

2. Passive recreational activities, such as walking trails; provided, that service facilities for such activities, including but not limited to parking, picnicking and sanitary facilities, are located outside of the buffer.

3. Clearing and re-vegetating the stream buffer for the purposes of improving its pollutant and silt removal efficiency may be permitted based upon clear and convincing proof that efficiency will be improved.

4. Stormwater control structures and temporary erosion control structures; provided, that:

a. The property owner or applicant demonstrates to the satisfaction of the Public Works Director and Planning Commission that such facilities cannot be practicably located outside of the stream buffer, and that any proposed stormwater control structure is sited and designed to minimize disturbance of the stream and stream buffer. Siting stormwater control structures away from the stream channel is preferable to siting such structures in the stream channel.

b. A vegetated buffer of a width not less than the minimum recommended by the Public Works Director is provided around the stormwater control structures.

c. Any land disturbed for construction of these structures is immediately revegetated.

5. Timber harvest operations; provided, that:

a. Along perennial streams the buffer must include, but is not limited to, a 50-foot permanent buffer of undisturbed natural vegetation and an additional 75-foot buffer area of selective logging leaving no less than 30 percent of the original standing timber; and

b. Along intermittent streams or drainages the buffer must include, but is not limited to, a 25-foot buffer area of selective logging leaving no less than 30 percent of the original standing timber; and

c. Vegetation sufficient to stabilize the soil shall be established on all disturbed areas. [Ord. 08-29, 2008].

21.40.120 Bridge Creek Reservoir buffer.

A 500-foot reservoir buffer must be maintained from the banks of the Bridge Creek Reservoir, measured at normal full water level. The reservoir buffer must remain in undisturbed natural vegetation. The facilities and improvements of the City water utility are exempt from this section. [Ord. 08-29, 2008].

21.40.130 Exceptions to buffers.

a. A conditional use permit is required for any intrusion into a required buffer including, but not limited, to those intrusions and exceptions listed in HCC 21.40.110(b). When any approved intrusion into a buffer involves excavation or clearing, the conditional use permit must require the disturbed area to be revegetated immediately.

b. Upon application of the property owner, the Planning Commission may grant a conditional use permit to reduce the reservoir buffer requirements on a case-by-case basis only if it finds that:

1. The full reservoir buffer would result in an exceptional hardship, depriving the property owner of the economic advantages of ownership, i.e., all potential for appreciation and all opportunity for development of the property. Mere failure to realize the maximum appreciation or full development potential from the property shall not be considered an exceptional hardship.

2. The intrusion into the reservoir buffer is the minimum necessary to relieve that exceptional hardship.

3. The intrusion will not cause a degradation of the water quality or endanger the suitability of the Bridge Creek Reservoir as a water supply source for the City’s public water utility.

In making such findings, the Planning Commission must consider topography, water quality protection, erosion potential, surrounding uses, the size of the parcel, and any other relevant factors. A site plan and an erosion and sediment control plan must be provided by the property owner. The Planning Commission must impose any conditions necessary to protect the water quality and ensure continued suitability of the Bridge Creek Reservoir as a water supply source for the City’s public water utility.

c. Upon application of the property owner, the Planning Commission may grant a conditional use permit, on a case-by-case basis, to pipe an intermittent or perennial stream, thereby reducing or eliminating stream buffer requirements, only if it finds that:

1. For intermittent streams, the owner demonstrates that such piping is necessary to allow reasonable use of the property or for purposes of public safety.

2. For perennial streams, the owner or applicant demonstrates that use of the property without such piping will cause an exceptional hardship, depriving the property owner of the economic advantages of ownership, i.e., all potential for appreciation and all opportunity for development of the property. Mere failure to realize the maximum appreciation or full development potential from the property shall not be considered an exceptional hardship.

3. The intrusion will not cause a degradation of the water quality or endanger the suitability of the Bridge Creek Reservoir as a water supply source for the City’s public water utility.

If the Planning Commission approves a conditional use permit for stream piping, it must impose conditions requiring a vegetated buffer area or other device approved by the Public Works Director to protect the stream at any intake structure and other conditions as necessary to control erosion and sedimentation. All buffers and physical improvements related to the stream piping must be located entirely on the affected property or on easements adjacent to the property. [Ord. 08-29, 2008].

21.40.135 Nonconforming lots, uses, and structures.

a. Except as otherwise provided in this section, lawfully subdivided lots, lawful existing uses, and lawfully constructed existing structures and improvements that are rendered unlawful by the adoption of this chapter or by any amendment to this chapter shall be treated as nonconforming.

b. No aspect of any nonconforming lot, use, structure, improvement, or any other kind of nonconformity in the BCWP district shall expand or increase in size or degree of nonconformance beyond the nonconformity existing on the effective date of the enactment that rendered it unlawful.

c. Nothing in this section shall be construed to exempt ongoing activities or pending plats from the requirements of HCC 21.40.070(g) or to be an exemption from any other provision of this chapter that specifically applies to any activity or thing in progress on the effective date of the enactment.

d. Nothing in this section shall be construed to allow any preexisting or ongoing violation of HCC 21.40.140 to continue. [Ord. 08-29, 2008].

21.40.140 Pollution prohibited.

No person shall pollute, poison, defile or corrupt the waters of the Bridge Creek Watershed nor throw or deposit offal, refuse, rubbish, garbage, dead animals, excrement, hazardous material, petroleum product, or any foul, offensive or noxious matter into the waters of the Bridge Creek Watershed or upon these waters when frozen, or upon the shores of these waters and the land constituting the watershed. No person shall cause, allow or permit any sewage, drainage, refuse or polluting matter that either by itself or in connection with other matter will tend to corrupt or impair the quality of the water of said watershed, or tend to render it injurious to health, to discharge, drain, percolate or permeate into the watershed. [Ord. 08-29, 2008].

21.40.150 Enforcement.

a. In the event that any person holding a conditional use permit issued under this chapter violates the terms of the permit or any person implements site development in such a manner as to adversely affect or endanger the water quality in the Bridge Creek Watershed, the City Planner may issue a stop work order or suspend or revoke a conditional use permit. A stop work order or suspension of a conditional use permit may be imposed immediately and without prior notice to stop or prevent imminent material harm to the water quality; provided, that notice and a reasonable opportunity for a hearing must be provided promptly after the issuance of the order or suspension. A conditional use permit may be revoked permanently or suspended for longer than 30 days only after notice and a reasonable opportunity for a hearing. A revocation or suspension of a conditional use permit for longer than 30 days must be done by written decision.
