<br />k. Placement of natural rock riprap and placement of a filter blanket shall be allowed without a permit if the
<br />finished slope does not exceed four feet horizontal to one foot vertical, the landward extent of the riprap is
<br />within ten feet of the ordinary high-water level and does not extend five feet below the ordinary high-water
<br />level, and the height of the riprap above the ordinary high-water level does not exceed three feet. A permit
<br />shall be required for placement of riprap which exceeds these standards.
<br />(Code 1982, 9 904.08(3))
<br />
<br />Sec. 30-2024. Placement and design of roads, driveways and parking areas.
<br />(a) Public and private roads and parking areas shall be designed to take advantage of natural vegetation and
<br />topography to achieve maximum screening from view from public waters. Documentation shall be provided
<br />by a qualified individual that all roads and parking areas are designed and constructed to minimize and control
<br />erosion to public waters consistent with the field office technical guides of the local soil and water
<br />conservation district, or other applicable technical materials.
<br />(b) Roads, driveways, and parking areas shall meet structure setbacks and shall not be placed within bluff
<br />and shore impact zones.
<br />(c) Public and private watercraft access ramps, approach roads, and access-related parking areas may be
<br />placed within shore impact zones, provided the vegetative screening and erosion control conditions of this
<br />division are met. For private facilities, the grading and filling provisions of section 30-2023(c) shall be met.
<br />(Code 1982, 9 904~08(4))
<br />
<br />Sec. 30-2025. Stormwater management.
<br />The following general and specific standards shall apply to stormwater management:
<br />(1) General standards.
<br />a. When possible, existing natural drainageways, wetlands, and vegetated soil surfaces shall be used to
<br />convey, store, filter, and retain storrnwater runoff before discharge to public waters.
<br />b. Development shall be planned and conducted in a manner that will minimize the extent of disturbed areas,
<br />runoffvelocities, and erosion potential, and reduce and delay runoff volumes. Disturbed areas shall be
<br />stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site.
<br />c. When development density, topographic features, and soil and vegetation conditions are not sufficient to
<br />adequately handle stormwater runoff using natural features and vegetation, various types of constructed
<br />facilities such as diversions, settling basins, skimming devices, dikes, waterways, and ponds may be used.
<br />Preference shall be given to designs using surface drainage, vegetation, and infiltration rather than buried
<br />pipes and manmade materials and facilities.
<br />(2) Specific stalulards.
<br />a. Impervious surface coverage of lots shall not exceed 25 percent of the lot area. In lieu of meeting this
<br />impervious surface requirement, a property may submit a stormwater drainage plan to the city for review and
<br />approval which restricts the developed five-year frequency event peak discharge to a rate no greater than the
<br />five-year historic undeveloped peak discharge. To the maximum extent possible, the drainage plan must also
<br />provide for methods of runoff settlement and/or filtration prior to discharge to the receiving water.
<br />b. When constructed facilities are used for stormwater management, documentation shall be provided by a
<br />qualified individual that they are designed and installed consistent with the field office technical guide of the
<br />local soil and water conservation districts.
<br />c. New constructed stormwater outfalls to public waters shall provide for filtering or settling of suspended
<br />solids and skimming of surface debris before discharge.
<br />(Code 1982, 9 904.08(5))
<br />
<br />Sec. 30-2026. Commercial, industrial, public, semipublic, agricultural, forestry and extractive uses.
<br />(a) Stal1dards for conznlercial, industrial, public, and senzipublic uses. Surface-water-oriented commercial
<br />uses and industrial, public, or semipublic uses with similar needs to have access to and use of public waters
<br />may be located on parcels or lots with frontage on public waters. Those uses with water-oriented needs shall
<br />meet the following standards:
<br />(1) In addition to meeting impervious coverage limits, setbacks, and other zoning standards in this division,
