Town of McCandless, PA D Development District Performance Standards

The D Development District is a zoning district which permits a range of uses appropriate to the McKnight Road corridor including the existing uses permitted in the current zoning classifications. These uses are governed by a series of standards designed to protect the sensitive natural resources along the corridor and to insure that adjacent properties are adequately and effectively buffered from dissimilar uses and intensities of development.

§ 1314.02 Land use intensity.

[Ord. 964, passed 10-26-1987; Ord. 1052, passed 4-22-1991]

(a)

Introduction. Land use intensity refers to the magnitude of a given land use on any site within the D Development District. The maximum permitted use is determined by the site capacity analysis described in Section 1314.03. Within the D Development District a range of different uses is permitted as set forth in Article 1326. To allow for this flexibility in types of uses, the intensity of site development is regulated to insure adequate protection of adjacent land uses.

(b)

Land use intensity class standards. The land use intensity class standards, (see Figure 1), designate "class" ratings for permitted intensity of land use within the district. Class I represents the least intense and Class VIII represents the most intense use permitted within the district. Each class has a series of corresponding regulations that govern the permitted levels of site development, density of dwelling units, requirements for site landscaping, building heights, open space and recreational land. The specific categories are as follows:

(1)

Maximum density (gross). This pertains to residential uses only and is a measure of the total number of dwelling units permitted per acre within the D Development District. Maximum density is the quotient of the total number of dwelling units divided by the base site area.

(2)

Maximum impervious surface ratio. This is a measure of the land use intensity which is determined by dividing the total area of all impervious surfaces (asphalt, concrete, building coverage or any other surface that does not permit water to penetrate into the ground) by, in the case of residential uses, the base site area or, in the case of nonresidential uses, by net buildable site area.

(3)

Maximum floor area ratio (FAR). This is a measure of the maximum allowable floor area for a given land use and is determined by multiplying the FAR by the basic site area.

(4)

Site design standards. There are FAR designations for these standards - R, A, B and C. These standards are keys to Section 1314.05 and 1314.07. The site design standards specify the minimum requirements under these sections for all classes.

(5)

Maximum height (feet). This defines the permitted building height permissible within the D Development District. It is measured by taking the mean ground elevation along the perimeter of the building and calculating the height to the eave line of the roof in the case of a sloped roof or to the top of the roof structure for all other roofs. Enclosed spaces within roof forms above the permitted height shall remain as unoccupied spaces. Parapets, screening walls, mechanical penthouses, and other architectural elements intended to screen and/or shield rooftop mechanical equipment shall be permitted to extend above the permitted height. The maximum height for medical office, small-format hospital, and institutional uses containing the lower maximum floor area ratio in Land Use Classifications VI through VIII may exceed the maximum heights set forth in Figure 1, provided that the maximum height does not exceed 65 feet.

[Amended 6-25-2018 by Ord. No. 1476]

(6)

Minimum open space ratio (residential use only). This is a measure of the minimum requirement for undeveloped open space on a development site that shall be developed specifically for recreational purposes. Any portion of resource protection land which is improved for recreation purposes may be included as contributing to the total requirements for recreational land. This ratio is used in the site capacity calculations for recreational land (see Figure 1).

(7)

Maximum density factor (residential use only). This measure of intensity yields the maximum number of dwelling units per acre of net buildable land. This factor is used in the determination of site capacity calculations (see Figure 1).

(8)

Recreation factor (residential use only). This is a measurement of the minimum requirement for land to be developed for recreational use. (See Figure 1.)

§ 1314.03 Site capacity analysis.

[Ord. 964, passed 10-26-1987; Ord. 1360, passed 4-28-2008]

(a)

Introduction. The intensity of use on any site within the D Development District is governed by the site capacity analysis. This analysis is performed to determine the physical qualities of the site that are suitable for development. The calculations required by this Code to determine the site capacity pertain to both residential uses and nonresidential uses.

There are three basic steps in the site capacity analysis process which are as follows:

(1)

Determination of base site area;

(2)

Determination of sensitive natural resources which shall be preserved; (Residential uses only) determination of recreational land to be provided; and

(3)

Determination of site capacity.

The calculations establish the permissible intensity of development on a given site. In the case of residential uses, the analysis yields the maximum number of dwelling units permitted on the site for both single-family and multi-family. Also, the minimum required open space and land dedicated to recreation is determined. In the case of nonresidential uses, the maximum permissible impervious surface area (see definitions, Section 1311.04) and the maximum permitted floor area are determined.

This information is then cross-referenced with the land use intensity class standards (Section 1314.02) to establish the appropriate classification for a proposed development. These class standards also specify the site development requirements for the individual classes.

(b)

Base site area (all land uses). The first step in the determination of the site capacity is to establish the Base Site Area.

(1)	Gross site area as determined by actual on-site survey.		_____acres
(2)	Subtract land constituting roads and land within ultimate rights of way of existing roads, rights of way of utilities and easements of access.		- _____acres
(3)	Subtract land which is not contiguous:
	A.	A separate parcel which does not abut, adjoin or share common boundaries with the rest of the development	- _____acres
	B.	Land which is cut off from the main parcel by a road, railroad, existing land uses or major stream, such that common use is hindered or that the land is unavailable for building purposes	- _____ acres
(4)	Subtract land which in a previously approved subdivision encompassing the same land, as part or all of the subject parcel, was reserved for resource reasons, such as flooding or for recreation		- _____acres
(5)	Subtract land used or proposed for residential uses, whenever both nonresidential and residential uses are proposed. (In the case of the site capacity calculation for the proposed residential use, subtract the land proposed for nonresidential use.)		- _____acres
(6)	Subtract estimated land required for bufferyard area. (Do not subtract bufferyard areas where they coincide with resource protection lands.)		- _____acres
(7)	Equals base site area.		= _____acres

(c)

Resource protection land. One of the principal factors that shall influence the intensity of development on a particular parcel of land is the requirements for protecting the sensitive environmental resources existing on the site.

Specific natural resources which are sensitive to development such as forests, steep slopes, floodplains and streams are protected under the provisions in this Code. All land area consisting of the natural resources or natural features listed in the following table shall be measured (reference definitions in Section 1311.04). The total acreage of each resource shall be multiplied by its respective open space ratio to determine the amount of resource protection land. When applying for a grading permit, consult Town grading specifications. The maximum slopes for cut and fill shall be as specified in Article 1705 of the Building Code.

Resource Protection and Special Natural Features Land
Resource/Natural Feature (All Districts)	Open Space Ratio	Acres of Land in Resource	Resource Protection Land (Acres in Resource x Open Space Ratio)
Drainageways	0.50	_____	_____
Floodplains	1.00	_____	_____
Mature Woodlands	0.85	_____	_____
Woodlands	0.70	_____	_____
Young Woodlands	0.40	_____	_____
Steep Slopes (12% - 15%)	0.60	_____	_____
Steep Slopes (16% - 25%)	0.70	_____	_____
Steep Slopes (25% or greater)	0.95	_____	_____
Hazardous Soils	0.95	_____	_____
Landslide Prone Area (See Section 1314.02(f))		_____	_____
TOTAL LAND IN RESOURCE		_____	_____
TOTAL RESOURCE PROTECTION LAND			_____

(d)

Mature woodlands; woodlands; young woodlands.

(1)

No more than 15% of any mature woodland may be cleared or developed. The remaining 85% shall be maintained as permanent open space. No more than 30% of any woodlands may be cleared or developed. The remaining 70% shall be maintained as permanent open space. No more than 60% of any young woodland shall be cleared. The remaining 40% shall be maintained as permanent open space.

(2)

Replacement of woodlands credit. In the case of mature woodlands, the developer may clear or develop more than the area otherwise permitted to be disturbed by this subsection, provided that the total mature woodland or woodland area disturbed shall not be increased by more than 50% of the area otherwise permitted to be disturbed. No more than 22.5% of mature woodlands may be disturbed. No more than 45% of woodlands may be disturbed. In addition:

The developer shall designate a new woodland area on a part of the site not forested.

The new woodland area shall consist of 1.2 times the surface acreage of the woodland area disturbed pursuant to this subsection.

(3)

No clearing or timbering of any woodlands may occur unless connected with an approved site plan.

(e)

Steep slopes. In areas of steep slopes, the following standards shall apply:

(1)

12% to less than 15% slope: no more than 40% of such areas shall be developed and/or regraded or stripped of vegetation.

(2)

15% of 25% slope: No more than 30% of such areas shall be developed and/or regraded or stripped of vegetation, with the exception that no more than 20% of such areas may be disturbed in the case of landslide prone areas.

(3)

More than 25% slope: no more than 15% of such areas shall be developed and/or regraded or stripped of vegetation, with the exception that no more than 5% of such areas may be disturbed in the case of landslide prone area.

(4)

The limitations on disturbance of landslide prone areas set forth in parts (2) and (3) above may be waived pursuant to the modification process in Article 1705 of the Town Code if the Developer presents to the Town for approval fully engineered plans for the removal and remediation of any rock, soils or other materials that create the landslide prone condition and, upon a favorable recommendation by the Town Engineer, the modification is approved by Council.

(f)

Landslide prone area. An area where the downward and outward movement of the slope-forming materials composed of rock, soils, artificial fills or a combination of these materials exist. (See Article 1314 Appendix map on landslide prone areas, soil types and locations).

(g)

Drainageways. Any area to which runoff from surrounding land flows naturally or is caused to flow from existing land alterations and which conveys such runoff to a watercourse. No more than 50% may be developed.

(h)

Existing plant material.

(1)

Existing, healthy plant material may be counted as contributing to the total plant material required by this Code except in the case of establishment of new woodlands.

(2)

Whenever an existing area meets the definition of woodland, it shall satisfy any planting required by this Code regardless of the mix of plant materials provided that understory trees and shrubs constitute at least 70% of the individual trees and shrubs present. If, understory trees and shrubs constitute less than 70% of the trees and shrubs present, additional plant material shall be installed in order to meet the requirements otherwise imposed. No tree greater than five inch caliper shall be counted if more than one-eighth of the area under its canopy or drip line is closer than 15 feet from a building, parking area or road.

(i)

Establishment and maintenance of woodlands.

(1)

Establishment. The establishment of a woodland shall conform to the following standards:

The minimum area shall be 1 1/2 acres.

No area of woodland shall be less than 50 feet wide.

The following plant material shall be provided per acre of woodland to be established. Fractional requirements (resulting from fractions of acres to be established) shall be rounded up.

Plant Materials Required Per Acre	Minimum Size Plant Materials
5 slower canopy trees	3 inch caliper
10 canopy trees	2 inch caliper
20 faster growing canopy trees	1 inch caliper
30 slower growing canopy trees	5 feet (height)
10 understory trees	1 inch caliper
100 shrubs	3 feet (height)

All existing healthy trees shall be preserved to the maximum extent possible.

All areas of a newly established woodland shall be seeded as lawn or prairie unless ground cover has already been established.

(2)

Maintenance of newly established woodland areas. Additional plants established by natural succession shall be retained. Dead trees shall be removed where they adjoin roads or buildings. Debris and litter shall be cleaned on an annual or semiannual basis. Damage to 15% or more of the stand due to disease, wind or fire shall require the replacement of all such damaged, trees.

(j)

Recreational land (residential uses only). This calculation is required of all residential land uses with the exception of subdivisions which would be required to provide less than one-quarter acre by the following calculation. Total recreational land required for residential uses is calculated as follows:

§ 1314.04 Bufferyards.

[Ord. 964, passed 10-26-1987; Ord. 1373, passed 6-15-2009]

(a)

Purpose. Bufferyards are required to separate different land uses to minimize or eliminate any potential negative impacts on adjacent uses. The location, required amount of land to be designated as a bufferyard, and the type and amount of planting is specified for each bufferyard. The width of the buffer may vary, however, depending on the intensity of planting and landscape configuration.

(b)

Location. Bufferyards shall be located along the outer perimeter of a lot or land parcel extending to the boundary line.

(c)

Determination of type. To determine the type of bufferyard required between two adjacent parcels or between a parcel and a street, the following procedure shall be followed:

(1)

Identify land use category of the proposed use;

(2)

Identify the land use intensity class of the proposed use and all adjacent property; and

(3)

Determine the bufferyard types required along each boundary by referring to the bufferyard type matrix. Each letter designates a specific bufferyard type.

The bufferyard shall be flexible. A single standard for all uses or even for any given pair of uses can both impose unnecessary hardship on the developer of a particular parcel and also lead to monotony. Within each class of bufferyard, a developer may choose from several options. Because different land values and plant material costs are introduced, the developer is given flexibility to make cost tradeoffs in deciding which option to select. Depending on the size of the parcel, this flexibility may become extremely relevant.

(d)

Requirements.

(1)

The following illustrations indicate the specifications for each bufferyard.[1] There are several options for bufferyard width with corresponding plant material requirements. The planting requirements are expressed as the material required per 100 linear feet of bufferyard. The "plant unit multiplier" assigned to each optional bufferyard width would determine the amount of planting material required for that particular width. Any calculations of five-tenths or greater for a particular type of plant shall be counted as a required plant material.

[1]

Editor's Note: The illustrations are included as an attachment to this chapter.

(2)

Each illustration depicts the total bufferyard located between two uses.

(3)

When development occurs adjacent to vacant land, this development shall provide the required bufferyard as specified in Figure 2. The second use to develop shall provide all additional planting and/or land necessary to provide the total bufferyard required between the two uses.

(4)

Existing plant material within the designated bufferyard area that meets the requirements for planting materials as set forth in this Code may be counted as contributing to the bufferyard planting requirements.

(5)

The following structures are equivalent and may be used interchangeably, so long as both structures are specified in the bufferyard illustrations in this section.

Structure	Equivalent Structure
F-3	B-1
F-4	B-2
F-5	B-3
F-6	BW-1
B-1	F-3
B-2	F-4
B-3	F-5
BW-1	F-6

(6)

Any existing plant material which otherwise satisfies the requirements of this section may be counted toward satisfying all such requirements.

(7)

The exact placement of required plants and structures shall be the decision of each user, except that the following requirements shall be satisfied:

Evergreen (or conifer) plant materials shall be planted in clusters rather than singly in order to maximize their chances of survival.

Berms with masonry walls (BW-1, BW-2 and BW-3) required of bufferyard J and K options are intended to buffer more significant nuisances from adjacent uses and, additionally, to break up and absorb noise, which is achieved by the varied heights of plant materials between the masonry wall and the noise source. When berms with walls are required, the masonry wall shall be closer, than the berm to the higher intensity use.

(8)

All bufferyard areas shall be seeded with lawn unless ground cover is already established.

(9)

Use of bufferyards. A bufferyard may be used for passive recreation; it may contain pedestrian or bike trails, provided that:

No plant material is eliminated;

The total width of the bufferyard is maintained; and

All other regulations of the Code are met.

(10)

Ownership of bufferyards. Bufferyards may remain in the ownership of the original developer (and assigns) of a land use, or they may be subjected to deed restrictions and subsequently be freely conveyed, or they may be transferred to any consenting grantees, such as adjoining landowners, a park or forest preserve district, municipality, or an open-space or conservation group, provided that any such conveyance adequately guarantees the protection of the bufferyards for the purposes of this article.

(11)

Maintenance of bufferyards. Bufferyards shall be maintained by the owner of the property. Debris and litter shall be cleaned on a semi-annual basis. Damage to 15% or more of the plant material for any reason, including disease, shall require replacement of all such damaged plant materials.

(12)

All bufferyard plant materials must meet the Plant Material Specifications set forth in Section 1314.05(d).

(13)

In lieu of planting bufferyards as required, and subject to prior approval of Town Council at its sole discretion, bufferyard plantings along roadways may be concentrated at the site entry point. This alternative shall not be applicable where double bufferyards are required.

§ 1314.05 Landscaping.

[Ord. 964, passed 10-26-1987; Ord. 1373, passed 6-15-2009]

(a)

Introduction. Off-street parking landscape requirements and general landscaping requirements: Each land use and intensity level have specific requirements for site landscaping and landscaping in the off-street parking areas. A minimum square footage as well as planting materials are specified (see Figures 3 and 4).

(b)

General landscaping requirements. This section details the general landscaping required of particular land uses. The number and type of plant units required per 300 linear feet of nonresidential building(s) perimeter comprising the subject land use are specified for standards R, A, B and C. The landscaping requirement specified for residential uses (R) is the requirements per 10 dwelling units. The definitions of this Code (defining plant units) shall be applicable to the terms utilized in this section. The requirements of this section shall be applied proportionately when the total linear feet of building(s) perimeter varies from 300 feet for nonresidential uses or 10 residential dwelling units. All required planting shall be located in areas which do not include any bufferyard or right of way. Existing plant materials which meet the requirements of this Code may be counted as contributing to the total landscaping required by this section.

The following table specifies the type and number of plant units required by this section.

Figure 3
Landscaping Standard	Number of Landscaping Units Required (per 300 feet or 10 dwelling units)
Standard	Canopy	Understory	Shrubs
R	5	5	0
A	5	5	25
B	7	7	30
C	8	8	35

(c)

Off-street parking landscaping requirements. This section details the landscaping required of all off-street parking areas exceeding five parking stalls. The number and type of plant units required per 24 automobile spaces is specified for each standard (A, B, C or R). Also specified is a minimum area within which the required planting shall be provided. Existing plant materials which meet the requirements of this Code may be counted as contributing to the total landscaping required by this section. The requirements of this section shall be applied proportionally to any number of spaces other than 24. Meeting the requirements contained in Article 1346, Appendix A(b)(13) ("Parking Lot Landscaping Requirements") shall constitute full compliance with this section.

§ 1314.07 Architectural guidelines.

[Ord. 964, passed 10-26-1987; Ord. 1373, passed 6-15-2009]

(a)

Development character. "Campus" Image. The Development District encompasses rolling, wooded hills interlaced with residential neighborhoods. The architectural character of projects developed within this corridor should preserve this quality and respect the residential scale through the appropriate massing and scale of the proposed buildings as well as materials' use and landscaping of the grounds. A "campus" character is the goal for developments within this district which shall extend the existing residential vocabulary of surrounding communities and preserve the environmental qualities of the land.

This character shall be achieved by using basic guidelines defining height restrictions (performance zoning), materials use, roof treatment, landscaping, site lighting and signage requirements. Those basic guidelines shall permit individual flexibility in design and treatment of proposed projects by specifying critical parameters. The Architectural Review Board shall assist the developers in further defining the intentions of quality and character guidelines and shall review submitted designs to assure that the appropriate character within this district is maintained. Council shall appoint three persons who own property within the Town to the Board for a four-year term. The Board shall advise the Planning Commission as to the acceptability of a proposed project, as it relates to development character and conformance with the architectural guidelines.

(b)

Design guidelines. To insure that multi-family and office/commercial projects within the district reflect a desirable image of the Town, the following architectural guidelines shall be incorporated into the District standards.

(1)

Material use. All primary and accessory structures shall be constructed primarily of a brick or clay tile material. Colors should be compatible with the surrounding residential community. The following materials are not permitted as primary exterior cladding within the Development District:

Concrete block;

Metal;

Wood siding; or

Asphalt/fiberglass shingles.

(2)

Glazing. Glazing areas shall not exceed 60% of the exterior skin of the building. Mirrored glazing is not permitted within the Development District, though solar absorption/reflective glazing is an acceptable material.

(3)

Roof structures. Buildings having up to and including two stories shall have sloped roofs with a minimum 6:12 pitch. Buildings of three stories or more may have sloped parapets that shall have the appearance of a solid roof or fully enclosed sloped roofs. Minimum parapet heights/slopes are as follows:

Three stories or 35 feet to 12 feet height at 12:12.

Four stories or 45 feet to 15 feet height at 12:12.

Buildings of three stories or more may also have fully enclosed roofs with a minimum of 6:12 pitch or highly articulated roof forms that express the building and at the same time shield exposed roof mounted mechanical systems from view.

Permitted roof materials shall be metal (copper, pre-finished aluminum, terne, stainless steel), slate or tile.

(4)

Screening. All mechanical equipment and trash collection areas shall be screened from public view and construction using materials consistent with the primary building.

(5)

Accessory structures. All accessory structures shall be constructed using materials consistent with the primary building.

(c)

Theaters, museums, auditoriums and fairgrounds shall be permitted marquee signs up to an additional 100% in area beyond that permitted for freestanding signs, provided that the area of other signs to which the theaters, museum, auditorium or fairground may be entitled is reduced. The increase in area permitted the marquee sign shall be equal to the reduction in area of other permitted signs.

Auxiliary signs. An auxiliary sign may be freestanding, attached to freestanding structures or equipment, or may be attached to the building or windows.

Freestanding signs. A freestanding sign shall not be located within any bufferyards required by the use of the site on which it is located.

Graphic signs. A graphic sign shall consist of or be constructed of the same material as the facade of which it is an integral part, with the exception that individual letters or symbols which do not project more than one inch from the facade need not be of the same material as the facade.

Super graphic. A super graphic shall consist or be constructed of the same material as the facade of which it is an integral part. No difference in material is permitted.

[1]

Editor's Note: The Table of Sign Performance Standards is included as an attachment to this chapter.

(d)

Exterior lighting standards.

(1)

Purpose. The purpose of this subsection is to regulate the spillover of light and glare on operators of motor vehicles, pedestrians and land uses in the proximity of the light source. With respect to motor vehicles in particular, safety considerations form the basis of the regulations contained herein. In other cases, both the nuisance and hazard aspects of glare are regulated. This subsection is not intended to apply to public street lighting.

(2)

Definitions.

CANDLEPOWER: The amount of light that will illuminate a surface one foot distant from a light source to an intensity of one footcandle. Maximum (peak) candlepower is the largest amount of candlepower emitted by any lamp, light source or luminaire.

CUTOFF: The point at which all light rays emitted by a lamp, light source or luminaire are completely eliminated (cutoff) at a specific angle above the ground.

CUTOFF ANGLE: The angle formed by a line drawn from the direction of light rays at the light source and a line perpendicular to the ground from the light source, above which no light is emitted.

CUTOFF-TYPE LUMINAIRE: A luminaire with elements such as shields, reflectors or fractor panels which direct and cut off the light at a cutoff angle that is less than 90°.

FOOTCANDLE: A unit of illumination produced on a surface, all points of which are one foot from a uniform point source of one candle.

GLARE: The brightness of a light source which causes eye discomfort.

LUMINAIRE: A complete lighting unit consisting of a light source and all necessary mechanical, electrical and decorative parts.

MAXIMUM PERMITTED ILLUMINATION: The maximum illumination measured in footcandles at the interior bufferyard line at ground level in accordance with the standards of subsection (d)(3) hereof.

(3)

The following standards are required of all exterior lighting except the outdoor recreational uses specifically exempted below. Many uses have the option of providing a lower light post with a noncutoff type luminaire or a higher pole, up to 60 feet, with a luminaire that totally cuts off light spillover at a cutoff angle smaller than 90°. The maximum height light post permitted is dependent on amount of cutoff provided. This is designed as a protection against excessive glare and light spilling over to neighboring properties. The exceptions which are permitted provide adequate protection for neighboring residential property. Exterior lighting shall meet one of the following standards:

When light source or luminaire has no cutoff:

Standard	Maximum Permitted Illumination	Maximum Permitted Height of Luminaire (feet)
R	0.20	10
A	0.20	15
B, C	0.30	20

Illustrations of this type of luminaire are provided below.

When a luminaire has total cutoff of an angle greater than 90°, the maximum illumination and the maximum permitted luminaire height shall be:

Standard	Maximum Permitted Illumination	Maximum Permitted Height of Post (feet)
R	0.3	15
A	0.5	20
B	0.75	25
C	1.0	30

An illustration of this type of luminaire is illustrated below.

When a luminaire has total cutoff of light at an angle less than 90° and is located so that the bare light bulb, lamp or light source is completely shielded from the direct view of an observer five feet above the ground at the point where the cutoff angle intersects the ground, then the maximum permitted illumination and the maximum permitted height of the luminaire shall be:

Standard	Maximum Permitted Illumination	Maximum Permitted Height of Luminaire (feet)
R	0.5	20
A	1.0	25
B	2.0	30
C	3.0	40

Exemption for specified outdoor recreational uses.

Because of their unique requirements for nighttime visibility and their limited hours of operation, ball diamonds, playing fields and tennis courts are exempted from the exterior lighting standards of this section. These outdoor recreational uses shall meet all other requirements of this section and this Code.

The outdoor recreational uses specified above shall not exceed a maximum permitted post height of eight feet.

The outdoor recreational uses specified above may exceed a total cutoff angle of 90°, provided that the luminaire is shielded to prevent light and glare spillover to adjacent residential property. The maximum permitted illumination at the interior bufferyard line shall not exceed two footcandles.

Additional regulations. Notwithstanding any other provision of this section to the contrary:

No flickering or flashing lights shall be permitted.

Light sources or luminaires shall not be located within bufferyard areas except on pedestrian walkways.

Measurement.

Metering equipment. Lighting levels shall be measured in footcandles with a direct-reading, portable light meter. The meter shall have a color and cosine-corrected sensor with multiple scales and shall read within an accuracy of plus or minus 5%. It shall have been tested, calibrated and certified by an independent commercial photometric laboratory of the manufacturer within one year of the date of its use.

Method of measurement. The meter sensor shall be mounted not more than six inches above ground level in a horizontal position. Readings shall be taken by qualified personnel only after the cell has been exposed long enough to provide a constant reading. Measurements shall be made after dark with the light sources in question on, then with the same sources off. The difference between the two readings shall be compared to the maximum permitted illumination. This procedure eliminates the effects of moonlight and other ambient light.

Exterior lighting plan. At the time any exterior lighting is installed or substantially modified, and whenever a zoning certificate is sought, an exterior lighting plan shall be submitted to the zoning office in order to determine whether the requirements of this section have been met.

§ 1314.08 Detailed use regulations.

[Ord. 964, passed 10-26-1987]

(a)

Residential use regulations. This section specifies the minimum lot dimensions and other requirements for each type of residential unit permitted by this Code. The regulations provide for lot sizes that vary with the number of bedrooms or size of house and with the type of housing. This gives the developer considerable freedom. For example, in areas where the site is best suited to smaller lots or dwellings, these can be accommodated without a zoning change so long as the overall intensity is balanced by the use of larger lots on other portions of the site.

Any type of single-family detached dwelling unit for which particular standards are not specified in this section shall comply with the requirements of a single-family house.

When a lot exceeds the minimum permitted area, all other standards applicable to the minimum lot area shall nevertheless apply. The figures specified in the tables of this section are expressed in terms of square feet, feet or a ratio, whichever applies. The off-street parking figures specify minimum number of off-street parking spaces. When the off-street parking is to be provided entirely on a lot and the required number of spaces is not a whole number, the number of required spaces shall be rounded up to the next higher whole number.

Reduction in number of off-street parking spaces: when a development is specifically designed to be used for senior citizens, all such units shall be required to provide one parking space for each such unit.

(1)

Conventional subdivisions. Use current R-1 and R-2 standards.

(2)

Performance subdivision. (Replaces R-3, R-4 and R-5 standards). Performance subdivisions may contain one or more of the housing types that are specified in this subsection. Refer to Section 1701 of the Building Code for regulations governing fire detection, fire wall separation and suppression.
