Sec. 59-C-5.3. Development standards.

	I-1	I-2	I-3	I-4	R&D	LSC
59-C-5.31 Building height.
No building shall exceed the following height limits:
(a) Normally:
—In stories	3	5		3
—In feet	42	70	100	42	50	200
(b) In the I-1 zone, this height may be increased under Section 59-C-5.41.
59-C-5.32. Coverage limitations. (Percent of gross tract area)
—Minimum green area	10	10	35	203	30
—Minimum public use space in the LSC zone; however, such space may be provided in part or entirely off-site on a separate lot or parcel in the same zone.  A payment instead of all or some of the required public use space may be made at the time of site plan review, if approved under the applicable provisions of Section 59-D-2.31.						20
—Off-street parking is not allowed to occupy more than			451
59-C-5.321. Maximum density of development.2  The maximum density of development must not exceed the following floor area ratio, which is to be based on and may be averaged over the gross tract area.					0.30
In the I-3 and LSC zones, the maximum density of development must not exceed the following floor area ratio, based on gross tract area, which may be averaged over 2 or more lots created by the same subdivision plan if the density is recorded by covenant in the land records for all affected lots. When averaging is used for previously approved subdivision plans the total development density must not exceed the density for which Facility approval was previously granted, unless a new Adequate Public Facility test is applied. In such situations, the shift of density must be recorded in the land records for all affected lots. In the LSC Zone, if an applicant for a preliminary plan or site plan;   1) owns more that one tract of land; or   2) owns a tract of land, controls the total gross floor area on another tract of land not owned by the applicant, and the density transfer is consistent with the applicable master or sector plan’s recommendations, the floor area ratio in one portion of the gross tract area may exceed the maximum floor area ratio of the zone only if the floor area ratio for the total tract area does not exceed the maximum floor area ratio. The maximum floor area for each lot and parcel comprising the subject tracts must be shown in documents, including an easement and appropriate releases, in a recordable form approved by the Planning Board.  The Planning Board must determine compliance with the densities shown in the documents when a site plan application is before it.  The documents must be recorded in the land records before a building permit is approved. In the LSC zone, any density above a floor area ratio of 0.50 must be supported through the purchase of a BLT easement under Section 59-C-5.473.			0.50			2.04
In the I-3 zone, the maximum density may be increased up to a maximum floor area ratio of 0.60, provided that the applicant for development obtains approval of a traffic mitigation agreement at the time of site plan review that will result in traffic generation equal to or less than a project with a floor area ratio of 0.50.
59-C-5.322. Requirement for landscape plan.  In the R&D zone, the preliminary plan of subdivision must include a landscape plan and a plan for the preservation of natural features.

 

1   In unusual circumstances, may be waived by the Planning Board at the time of site plan approval upon a finding that a more compatible arrangement of uses would result.

2   An entire floor or story or a portion of a floor or story used exclusively for mechanical equipment is excluded from the maximum density of development calculation, and no portion of any floor or story excluded from the maximum density calculation that exceeds the Floor Area Ratio of the zone may be used for any other purpose.  The aggregate area of any partial floors or stories excluded from the maximum density of development calculation must not exceed the gross floor area of any full floor of the building.

3   May be reduced in a Transit Station Development Area under 59-C-5.44(f).

4   Non-residential uses.  In order to maintain an appropriate emphasis on the purpose of the LSC Zone, the following minimum and maximum percentages of the total non-residential gross floor area proposed in a concept plan, preliminary plan, or site plan are required for tracts under common ownership larger than 5 acres:

   Life sciences - 40 percent minimum of the gross floor area proposed; the proposed gross floor area used for the purpose of calculating the minimum percentage of life science uses excludes: (1) hospitals and the hospital’s accessory uses; and (2) educational facilities.

   All retail uses - 10 percent maximum of the gross floor area proposed; however, if the Planning Board finds that unique circumstances are present and the area would be enhanced by additional retail activity, then a maximum of 15 percent of the gross floor area proposed may be used for retail purposes.

   Residential uses - The maximum residential density, excluding dormitories, must not exceed 30 percent of the permitted FAR.
