1.
No provision stipulated herein shall prohibit a building from being situated adjacent to a railroad right-of-way for purposes of loading and unloading materials.
2.
Or not less than 200 feet where a building abuts a residential district; except that when a railroad right-of-way is situated between a building and a residential district, then the yard distance shall be not less than 100 feet.
3.
Floor Area Ratio. The maximum gross floor area of a building within the LM District shall be based upon the percentage proportion of the gross floor area to be utilized for offices versus research laboratories and/or limited manufacturing as defined in Section 16-2 of this chapter; specifically, the following floor area ratios shall apply to the LM District, with allowable square footage derived for any "critical" acreage on a site transferred to the "non-critical" acreage:
Percentage of Gross Floor Area Utilized By Offices | Maximum F.A.R. For Non-Critical Acreage | Maximum F.A.R. For Critical Acreage |
|---|---|---|
0% to 40% | 0.175 | 0.035 |
Over 40% to 60% | 0.125 | 0.025 |
Over 60% to 100% | 0.08 | 0.016 |
In reviewing submitted applications for development in order to determine the percentage proportion of office versus research laboratory and/or limited manufacturing use, the Board shall be guided by the fact that a basic premise and purpose for distinguishing between office versus research laboratory and/or limited manufacturing space within buildings is to equalize the traffic impact emanating from a given square footage of building space within the District; therefore, any building space likely to generate a floor/space occupancy rate equal to or less than 350 square feet per person shall be classified as "offices". |
Moreover, all main building lobbies, hallways, stair-wells, elevator shafts, and mechanical equipment rooms and storage areas shall be deemed "common areas", and the aggregate square footage of such common areas shall be counted as office versus research laboratory and/or limited manufacturing space in direct proportion to the gross floor area otherwise specifically determined to be office versus research laboratory and/or limited manufacturing space. |
Thereafter, the entirety of the gross floor area of the building shall be designated as "office area", "research laboratory area", or "limited manufacturing" for the purpose of determining the maximum F.A.R., and the applicant shall submit floor plans specifically indicating the location and extent of the three areas, with a specific indication and quantification of the common areas which have been allocated to the office, research laboratory and/or limited manufacturing square footage. |
In instances where the applicant is seeking site plan approval prior to being able to commit a portion or portions of a building to one of three areas noted above, the non-committed portion or portions shall be considered offices for the purpose of determining the percentage proportion of the gross floor area of the building to be utilized for office versus research laboratories, and/or limited manufacturing. |
4.
Lot Coverage
Percentage of Gross Floor Area Utilized by Offices | Maximum Lot Coverage |
|---|---|
0% to 40% office | 42.5% |
Over 40% to 60% office | 37.5% |
Over 60% to 100% office | 32.5% |
e.
General Requirements.
1.
Any principal building may contain more than one use or organization. Any lot may contain more than one principal building, provided that the minimum lot size is at least 20 acres and that all land coverage requirements of this chapter are met.
2.
Within the required front yard area and at least 50 feet adjacent to any lot line, there shall be no parking and, except for access driveways, the area shall be planted and maintained in lawn area or ground cover and landscaped with evergreen shrubbery.
3.
No merchandise, products, waste, equipment or similar material or objects shall be displayed or stored outside.

All areas not utilized for buildings, parking, loading, access aisles and driveways or pedestrian walkways shall be suitably landscaped with shrubs, ground cover, seeding or plantings and maintained in good condition. A portion of the required landscaped area may contain a permanent water area.
6.
No critical acreage shall be developed.
7.
Parking lots on adjacent properties shall be interconnected via common driveways through side and/or rear yard areas where feasible and when approved by the Planning Board or Zoning Board of Adjustment, as the case may be, in order to promote a planned off-street traffic circulation pattern which minimizes the necessity to utilize public streets.
f.
Minimum Off-Street Parking. Each individual use shall provide parking spaces according to the following minimum provisions:
1.
One space for every 1,000 square feet or fraction thereof of net habitable floor area used for inside storage, plus one space for every 500 square feet or fraction thereof of net habitable floor area used for research laboratories and/or limited manufacturing, plus one space for every 250 square feet or fraction thereof of net habitable floor area used for offices; provided that the minimum number of parking spaces resulting from the application of these provisions to the subject building shall not be increased by more than 10%.
g.
Minimum Off-Street Loading. The provisions specified in Subsection 16-4.5g of this chapter shall apply.
h.
Permitted Signs.
1.
Each principal building may have one freestanding sign along each road which the property abuts, provided that there is at least 250 feet of unbroken frontage, plus each principal permitted use may have one attached sign, provided and in accordance with the following:
(a)
Any freestanding sign shall not exceed 40 square feet in area, shall be set back at least 15 feet from any street right-of-way line and 25 feet from any other property line and shall not exceed eight feet in height.
(b)
Each principal use in a building with direct access from the outside shall be permitted a sign attached flat against the building. The size of each such attached sign shall not exceed 1/2 square foot of sign area per one linear foot of building facade fronting on a street and occupied by the individual use, but in no case shall the size of the sign exceed 50 square feet in area.
2.
Additionally, each subdivided development park may have one freestanding sign along each abutting arterial or collector road which provides vehicular access to the development, provided there exists at least 250 feet of unbroken frontage. Such sign(s) shall not exceed eight feet in height, shall be set back at least 15 feet from any street right-of-way line and driveways and 25 feet from any other property line, shall not exceed an area of 50 square feet, and shall be used only to display the development's name.
3.
For each multi-tenant building or each building on a single lot or in a subdivided development park, one directory sign listing the building names or addresses and/or tenants may be permitted within the internal circulation system, provided that the sign is set back at least 60 feet from any street or property line and is no larger than 20 square feet in size or eight feet in height.
