If the existing residence or lot is not connected to county sewer and if an applicant for a building permit establishes that the minimum threshold height prevents gravity flow connections to county sewer, the planning and zoning director, upon the recommendation of the watershed management director or designee, may grant an administrative variance to allow the threshold height to be up to five feet above the threshold of the previously existing residence in order to allow for gravity flow into the existing sewer tap. Should a greater increase in threshold height be required, a variance from the zoning board of appeals must be obtained in accordance with the process set forth in article VII of this chapter.

(4)

Topographical conditions. If exceptional topographical restrictions exist on the subject lot that were not created by the owner or applicant, then the planning and zoning director may grant an administrative variance to allow the threshold to be up to three feet above the threshold of the previously existing house.

(Ord. No. 2016-06-07, att. (5.4.4), 7-11-2016)

(a)

Intent. Transitional buffers are intended to create a visual screen in order to diminish the potential negative impacts of nonresidential and mixed land uses on adjacent residential land uses. Similarly, transitional buffers diminish the potential negative impacts of higher intensity residential development on adjacent single-family residential land uses.

(b)

General requirements. Natural or planted transitional buffers required by this division shall be established and permanently maintained by the property owner as follows:

(1)

The required transitional buffer shall be depicted in detail on each site plan or plat prior to final approval. Type and location of natural and planted vegetation shall be included.

(2)

Within the transitional buffer, the natural topography of the land shall be preserved and existing growth shall not be disturbed except where necessary to remove dead or diseased trees and undergrowth or to enhance the buffer with additional landscaping in order to provide a screen so as to prevent view of the higher density development from the lower density development.

(3)

Grading or construction adjacent to the transitional buffer zone shall not disturb or encroach upon the transitional buffer zone.

(4)

Notwithstanding subsection (b)(3) of this section, if grading is required in the transitional buffer in order to prevent or control erosion, the area of such grading shall cover no more than 20 percent of the required transitional buffer, shall be immediately replanted upon completion of easement improvements and shall avoid disturbance of the soil within the dripline of trees within the transitional buffer.

(5)

Any approved utility crossings shall be perpendicular to the transitional buffer.

(6)

A pedestrian walkway, a maximum width of five feet, may be located in the buffer to provide pedestrian access to the adjoining property. Where a pedestrian walkway is provided, a gate shall be installed in the required screening fence.

(7)

If existing vegetation in a buffer area does not meet the transitional buffer standards, a five foot high, landscaped berm may be installed subject to the approval of the city arborist. Grading to construct the berm shall not remove significant plants designated by the city arborist as part of the approval of the landscaped berm.

(c)

Buffer planting and materials. When the conditions of the existing natural topography and vegetation are insufficient to achieve the visual screening required by this section, a landscape planting plan to enhance the transitional buffer shall be prepared and implemented to supplement existing natural growth or to provide new plant materials of such growth characteristics as will provide a screen meeting the standards below:

(1)

Planting height. Proposed planting as part of an enhanced transitional buffer shall have a height of at least six feet at the time of planting and planted in a minimum of two rows, with staggered on center spacing such that a continuous opaque screen is created within two years of planting.

(2)

Plant types. Plant species in an enhanced transitional buffer shall be evergreen, native, naturalized or other species well-adapted to the local climate and rainfall patterns, disease and pest-free, healthy and vigorous, and meet standard for American Nursery Stock, ANSI Z60.1.

(3)

Plant functions. Plants shall be approved from a list made available from the planning and zoning department, but shall not be exclusive of other plants which may be suitable, provided they can provide a continuous opaque screen.

(4)

Fences. Fences are required with transitional buffers and shall meet the requirements of section 46-1340.

(5)

Wall and fence finishes. Walls and fences shall be constructed with the finished or decorative side facing outward from the property.

(d)

Buffer dimensions and specifications. Table 5.2(a) identifies the transitional buffer class required for each zoning district based on the zoning district to which it is adjacent. Table 5.2(b) summarizes the minimum width of the required transitional buffer for each transitional buffer class (A-E).

Table 5.2(a). Transitional Buffer Class by District

*R= RE, RLG, R-100, R-85, R-75, R-60 (except when R-60 use is single-family attached).

**Where the Mixed Residential District has single-family units along an adjacent residential (R) boundary, then a transitional buffer is not required.

Open Space and Enhanced Open Space Calculations

(1)

For development projects with residential uses requiring enhanced open space, no lot or multifamily building shall be more than one-quarter mile distance from a designated enhanced open space. If site constraints limit access to the enhanced open space, the distance may exceed the minimum setback requirement of this subsection, subject to the approval of the planning and zoning director. Measurement of distance shall be based on the distance of road and/or pathway providing connectivity to the enhanced open space.

(2)

A development project with residential uses not within one-half mile distance to a public park or recreation facility that is required to provide enhanced open space shall incorporate at least one enhanced open space type identified as clubhouse/pool amenity, neighborhood park with active recreation, and/or playground.

(3)

For development projects with residential uses within one-half mile of an existing or programmed public school, park, trail or library, the applicant for a land-disturbance permit shall provide for pedestrian access to the school, park, trail or library. If an existing or future pedestrian network and/or multi-use trail is identified by the city or county, the applicant may be required to provide a future reservation for such a connection. Where a programmed facility has no current concept design for potential alignment, an applicant for a land-disturbance permit requiring connection to a park shall meet with the parks and recreation department to determine whether any reasonable spur connection would be possible.

a.

For measurement of distance to a qualifying public amenity, measurement shall be taken along an improved walkway or sidewalk to the entrance of the public amenity.

b.

For measurement to nearby existing or proposed public trail or greenway, measurement shall be taken from a point along the exterior boundary of the development directly to the nearest point of the trail or greenway.

(d)

Enhanced open space. Enhanced open space shall be required as set forth in table 5.4. Standards for enhanced open space are found in tables 5.5 and 5.6. In addition, each function may be designated as either public (subject to the approval of and acceptance by the city) or private ownership.

(e)

Open space and enhanced open space standards.

(1)

Required open space shall conform to the zoning district requirements in article II of this chapter. Where table 5.4 conflicts with article II of this chapter, article II of this chapter shall prevail. Open space and enhanced open space design within an historic district that is subject to architectural design review shall require a certificate of appropriateness from the county historic preservation commission.

(2)

Lakes or ponds may be included as part of the open space requirements in a development, provided they are incorporated as part of enhanced open space design, subject to limitations of the riparian buffer as set forth in chapter 22.

(3)

Dry detention basins shall be designed by a professional engineer and may not count toward open space area requirements unless designed as an amenity or aesthetic feature.

(4)

Enhanced open space may include hard space surface areas in accordance with the permitted elements identified in table 5.6.

(5)

Below ground utilities or facilities may be located in the open space area.

(6)

Designated wetlands and dedicated conservation areas for native species and/or vegetation may count toward open space requirements in accordance with table 5.5.

(7)

Open space adjacent to existing buildings that have historical or cultural significance may be counted toward the minimum required open space if made accessible for the common usage of the development. However, the enclosed building area may not be included in the minimum required open space requirement.

(8)

Stormwater facilities may be located within open space if the stormwater facility is designed and approved as an amenity and/or low impact stormwater management technique, and is in compliance with applicable regulation of chapter 22, including approved best management practices. Such facilities may be exempt from fencing, provided that the public health safety and welfare is not jeopardized by the lack of fencing as determined by the director of planning.

(f)

Open space requirements. No residential lots shall be allowed to extend into the required open space nor shall individual residential yards count toward open space requirements.

Table 5.4. Enhanced Open Space: Minimum Requirements

(g)

Enhanced open space standards and types.

(1)

Enhanced open space areas are areas readily accessible, practical, and generally acceptable for active or passive recreation uses. If able to meet these characteristics, enhanced open space areas may not include required setback areas, drainage easements required by the director of public works, dedications with existing aboveground facilities, or contain structures not intended for landscape or recreational purposes.

(2)

Maintenance of such areas is not the responsibility of the city unless formally established and approved by the city through legal agreements. Maintenance shall be the responsibility of the owner or homeowners association in a form approved by the city.

(3)

Total enhanced open space may be distributed throughout the project, but each individual enhanced open space type shall meet the enhanced open space dimensional standards of table 5.5.

(4)

Elements shown under the permitted elements column in table 5.6 are allowed for the various enhanced open space types. Other elements that are not listed may be allowed by the planning and zoning director if they are consistent with the enhanced open space type.

(5)

Table 5.5 establishes enhanced open space types and minimum dimensional standards. The minimum size for any enhanced open space type shown in table 5.5 may be reduced below the minimum amount if another enhanced open space type in the same development is increased by a corresponding amount above the minimum size shown in table 5.5. Table 5.5 is supplemented further by table 5.6 which provides design requirements for each type.

(6)

Table 5.6 establishes the requirements for each enhanced open space type and its associated design requirements. Elements may be required by specific development types according to table 5.6.
