260-901D of this code.
(2) Maximum building height extensions. The measured building height and maximum building height shall not exceed 31 feet, except that:
[Amended 9-24-2012 by Ord. No. 2012-23]
(a) The maximum building height may extend up to 33 feet if:
[1] The front and rear yards are each at least 57 feet in depth;
[2] Each side yard is at least 38 feet in width; and
[3] The lot area is at least 80,000 square feet.
(b) The maximum building height may extend up to 35 feet if:
[1] The front and rear yards are each at least 80 feet in depth;
[2] Each side yard is at least 40 feet in width; and
[3] The lot area is at least 160,000 square feet.
(3) Nonconforming lots. See §
260-1005 of this code for lot requirements with respect to legal nonconforming lots of record.
(4) Clustering in planned unit developments. In A District planned unit developments, minimum lot size per unit requirements are intended only as a limit on overall development density and not as a requirement that each individual unit be placed on a lot of the specified size. Therefore, in A District planned unit developments, single-family detached dwelling units may be clustered together so long as sufficient common open space is provided within the development to meet the average minimum lot size requirement of the development taken as a whole.
(5) Density adjustments in A District planned unit developments.
(a) Authority to approve increased density. The Plan Commission may recommend and the Board of Trustees may authorize a reduction of the minimum lot size per dwelling unit requirement, and thus an increase in the overall density of development, when approving a special use permit for a planned unit development in the A District.
(b) Maximum permissible adjustments and specific standards. The Board of Trustees may authorize an increase in the permitted intensity of development up to, but not in excess of, the maximums hereinafter provided for upon compliance by the planned unit development with the conditions hereinafter set forth with regard to such maximums:
[1] One unit per 120,000 square feet. Intensity of use may be increased to a minimum average lot size per dwelling unit of 120,000 square feet if the Board of Trustees finds that the following conditions are satisfied:
[a] The planned unit development is adequately serviced by public sewers or, where such public sewers are not currently available or are not adequate, the applicant has established the ability, willingness and commitment (including the posting of a satisfactory guarantee of performance) to provide such facilities either by extending such sewers in a manner approved by the Board of Trustees as consistent with the Comprehensive Plan, the Village's current sewer program and ordinances and the best overall interests of the Village considering all of its current needs, obligations and goals; or by making a cash contribution, in an amount deemed adequate by the Village in light of the benefit to be received by and the burden to be imposed by the planned unit development, to a fund established to implement Village plans for constructing public sewers to serve an area or areas including the area of the proposed planned unit development; and
[b] The planned unit development is adequately supplied with water from the public water system or, where not so supplied, the applicant has established the ability, willingness and commitment (including the posting of a satisfactory guarantee of performance) to provide a water supply system by extending mains of the public water system in a manner approved by the Board of Trustees as consistent with the Comprehensive Plan, the Village's current water supply program and ordinances and the best overall interests of the Village considering all of its current needs, obligations and goals; or by making a cash contribution, in an amount deemed adequate by the Village in light of the benefit to be received by and the burden to be imposed by the planned unit development, to a fund established to implement Village plans for constructing public water mains and facilities to serve an area or areas including the area of the proposed planned unit development; and
[c] The planned unit development is adequately served by public streets with sufficient capacity to accommodate any projected traffic increase; and
[d] The planned unit development provides storm drainage and retention facilities which reduce the risk of flooding and damage from storm runoff in the Village and which meet the minimum standards established by the Bannockburn storm and sanitary sewerage systems and facilities regulations.
[2] One unit per 80,000 square feet. Intensity of use may be increased to a minimum average lot size per dwelling unit of 80,000 square feet if the Board of Trustees finds that the following conditions, in addition to the conditions set forth in the foregoing Subparagraph [1], are satisfied:
[a] The subject property comprising the planned unit development is either zoned in Lake County for permitted uses more intense than single-family dwellings on lots of 120,000 square feet and subject to a petition to annex to the Village of Bannockburn; or located adjacent to the Milwaukee Road railroad tracks; and
[b] The planned unit development provides direct vehicular access to either Route 22 or Waukegan Road; and
[c] The planned unit development provides special environmental amenities such as the perpetual preservation of significant wooded areas or natural prairie land or the provision of natural or man-made lakes; and
[d] The planned unit development demonstrates excellence in site planning, layout and landscaping; and
[e] The planned unit development provides, both for the total development and for each separate lot within it, a maximum lot coverage of 2,000 square feet plus 20%.
[3] Inclusion of streets. The maximum intensity of development permitted in an A District planned unit development may be increased to the extent of including the area of all streets and rights-of-way in excess of a width of 22 feet as part of the required minimum area per dwelling; provided, however, that no such increase shall be allowed unless the Board of Trustees shall expressly find such increase to be necessary to compensate for the developer's installation of streets of unusual length in order to accommodate unusual physical features of the site or to preserve specific natural features of the site.
(c) General standards for adjustment. No such adjustment shall be recommended or authorized except on the basis of the development's achieving the purposes for which planned unit developments may be approved pursuant to §
260-1163B of this code and satisfying the standards applicable to such developments as set forth in §
260-1163E of this code.
(6) Lot dimensions and yards in A District planned unit developments.
(a) Authority to waive. The Plan Commission may recommend and the Board of Trustees may authorize the waiver of the lot dimension and yard requirements of the A District when approving a special use permit for an A District planned unit development.
(b) Special requirements; limitation of waiver authority. Special landscaping, perimeter treatment, and spacing requirements for planned unit developments are set forth in §
260-1163E(2)(f) and
(g) of this code. Such requirements shall not be waived under any circumstances.
(c) Standards for waiver. Such waiver shall be recommended or authorized only if the development achieves the purposes for which planned unit developments may be approved pursuant to §
260-1163B of this code and satisfies the standards and procedures applicable to such developments as set forth in §
260-1163E and
H of this code.
(7) Special setbacks for signs. Special setbacks established for some signs by §
260-906F and
H of this code shall control over the yard and setback requirements established in the table.
(8) Permitted obstructions in required yards. See §
260-909 of this code for certain structures and uses that may be located in certain required yards.
(9) Special street setbacks. No building or use or accessory building or use or any part thereof shall be erected or conducted within 90 feet of the center line of Wilmot Road or Telegraph Road, or within 83 feet of the center line of any other street.
(11) Side and rear yard regulations for accessory structures and uses. Accessory structures and uses may be located in required side or rear yards, provided said accessory structure or use is located not less than 15 feet from the side and rear lot lines; and provided, further, that any accessory structure of more than 10 feet in height shall be set back one additional foot from said lot lines for each foot or fraction thereof by which said structure exceeds 10 feet in height; provided, however, that this regulation shall not apply to residential recreational facilities, stables, or antennas and antenna support structures; and provided, further, however, that no accessory structure or use, or any combination of such structures or uses, located within an otherwise required side or rear yard pursuant to this subparagraph shall occupy more than 30% of such required yard.
(12) Rear yard regulation exception for decks. Decks may be located in rear yards, provided they are located at least 40 feet from the rear lot line in the A District and 25 feet from the rear lot line in the B District.
(13) Maximum lot coverage in certain planned unit developments.
(a) Density adjustments. See Subparagraph G(5)(b)[2][e] of this section [Footnote (5) above] regarding permissible density adjustments in A District planned unit developments.
(b) Certain planned unit developments (average lot size of 80,000 square feet). Notwithstanding the maximum lot coverage restrictions of Subsection E, an A District planned unit development authorizing the development of one unit per 80,000 square feet in area pursuant to Subparagraph G(5)(b)[2] of this section that also includes the area of streets within the lot area pursuant to Subparagraph G(5)(b)[3] shall be subject to a maximum lot coverage restriction of 2,000 square feet plus 20% for any one lot and for the development as a whole; provided, however, that a variation may be granted pursuant to the procedures in §
260-1153 of this code to authorize a maximum lot coverage of 25% for a lot that does not meet the 2,000 square feet plus 20% maximum lot coverage restriction as of December 11, 2006.
(14) Spacing regulation exception for specified structures. This limitation shall not apply to air-conditioning units, decks, antennas, or antenna support structures, nor to any accessory structure protected by a fire separation wall approved by the Building Commissioner.
(15) Credit for right-of-way dedication. For any zoning lot included within the A Residential District that has any frontage along Half Day Road (Illinois Route 22), to the extent that any land from such lot is dedicated or otherwise conveyed for right-of-way purposes for Half Day Road, the Half Day Road lot line(s) for such lot shall be deemed to be the lot line(s) as existing on September 22, 2008. The prededication lot area and dimensions of such lot shall be applied for purposes of calculating lot area and dimensions, yards, gross floor area, and lot coverage requirements; provided, however, that this provision shall not apply to any zoning lot from which additional right-of-way has been taken, dedicated, or otherwise conveyed beyond the rights-of-way lines set forth in the Illinois Department of Transportation Plats of Highway for Illinois Route 22, consisting of 16 pages, and dated September 22, 2008.
