          Use as redeveloped:   Commercial

          Site as redeveloped:   Office complex with limited retail and commercial facilities, total of 400,000

                                                square feet in five buildings

1.       If constructed in Baltimore County, Maryland:

a.       Authority:  Baltimore County Zoning Regulations (amended through July 6, 1998)

b.      Under § 207, the most appropriate zoning would be O-3 (Office Park) Zone.

c.       With regard to O-3 land use requirements, §§ 207.3 and 207.4 incorporate by reference the OR-2           requirements.

d.      In addition to use as offices, § 206.3 also authorizes a variety of commercial activities.

e.       § 206.4.C.5 imposes a maximum floor area ratio of 0.5.  This assumes that the building is a Class B

Office Building.  § 101 defines a Class B Office Building as an office building that was not originally constructed as a one or two family dwelling.  The project as redeveloped would fall within the definition of a Class B Office Building.

f.       Given a maximum floor area ratio of 0.5, the minimum amount of land area that would be required

          by the project would be 800,000 square feet.

g.      The parking (§ 409.A.2) and loading zone (§ 409.11) mandates could be accommodated within the

          minimum land required by § 206.4.C.5.

Office Building.  § 101 defines a Class B Office Building as an office building that was not originally constructed as a one or two family dwelling.  The project as redeveloped would fall within the definition of a Class B Office Building.

d.      Given a maximum floor area ratio of 0.5, the minimum amount of land area that would be required

          by the project would be 29,200 square feet.

e.       The parking (§ 409.A.2) and loading zone (§ 409.11) mandates could be accommodated within the

          minimum land required by § 206.4.C.5.

f.       29,200 square feet = 0.67 acres.

g.      Estimated BF/GF Trade-Off:  0.17:0.67 = 1:3.94

2.       If constructed in Carroll County, Maryland:

a.       Authority:  Carroll County Maryland – Zoning Ordinance (amended through September 1, 1996)

b.      Under § 14.6, the most appropriate zoning would be B-G (General Business) District.

c.       § 14.63(c) establishes a 25% maximum tract coverage limitation.

d.      The 25% maximum tract coverage limitation would require a total land area of 29,200 square feet.

e.       § 14.63(d) incorporates by reference the parking and loading zone requirements of § 14.1.  The

minimum land area requirement imposed by § 14.63(c) is sufficient to accommodate both the parking (§ 14.1(a)(23)) and loading zone (§ 14.1(b)(10)) requirements.

f.       29,200 square feet = 0.67 acres.

g.      Estimated BF/GF Trade-Off:  0.17:0.67 = 1:3.94

3.       If constructed in Frederick County, Maryland:

a.       Authority:  Zoning Ordinance, Frederick County, Maryland (amended through March 30, 2001)

b.      Under § 1-19-289, it would be most appropriate to locate the project in the Office/Research Industrial

          District.

c.       § 1-19-290 imposes a 40,000 square foot minimum lot size requirement.

d.      § 1-19-308.1(3) imposes a 20% open space requirement.  (The setbacks required by § 1-19-290 may

          be located in open space areas.)

e.       The parking (§ 1-19-167) and loading zone (§ 1-19-168(2)(f)) mandates would require a total land

          area of 7,860 square feet.

f.       The total area of the footprints of the project buildings plus the parking and loading zone

requirements = 15,160 square feet.  When the 20% open space requirement of § 1-19-308.1(3) is included, the minimum area required for the project becomes 18,192 square feet.

g.      18,192 square feet = 0.42 acres.

h.      Estimated BF/GF Trade-Off:  0.17:0.42 = 1:2.47

 


 

APPENDIX F – 9

(Burlington, Vermont Study Area)

SITE:          BUR – 1

          Site acreage:                0.40 acre

          Use as redeveloped:   Multifamily residential

          Site as redeveloped:   One single family residential building and one multifamily residential building

                                                on a single lot

1.       If constructed in the Town of Colchester, Vermont:

a.       Authority:  Town of Colchester, Vermont Zoning Regulations and Official Zoning Map (amended

          through April 14,1999).

b.      § 1.310 of the “Table of Permissible Uses” allows for multiple family residential development under

          the following zoning classifications: R-1, R-2, R-3, GD-1, GD-2 and GD-3.

c.       Under § 902.2, Planned Residential Development standards are applicable to the development of

          multifamily residential facilities in the low or medium density residential districts (R1, R2 and R3).

d.      § 1503.3 of the Planned Residential Development standards includes open space requirements.

e.       Under § 905, the maximum lot coverage in zoning classifications R-1, R-2 and R-3 is 20%.

f.       Because of these open space and maximum lot requirements, construction of the facility under R-1, R-

          2 or R-3 zoning classifications was not given further consideration.

g.      Multiple family residential development is permitted within the GD-1 zoning classification but only if

          the development complies with the aforementioned Planned Residential Development standards.

h.      The “Dimensional Requirements” (Table 1) require 10,000 square feet per dwelling unit (both single

          family and multiple family) within the GD-3 zoning classification.

i.        However, the “Dimensional Requirements” only mandate a 20,000 square foot minimum lot size for

          multifamily residential development in the GD-2 district.

j.        Because it would have required the minimum amount of land, the 20,000 square feet requirement of

          the GD-2 zoning classification were assumed.

k.       20,000 square feet = 0.491 acres.

l.        Estimated BF/GF Trade-Off:  0.40:0.491 = 1:1.15.


 

2.       If constructed in the Town of Milton, Vermont:

a.       Authority:  Town of Milton, Vermont Zoning Regulations (amended through December 28, 1998)

b.      Under § 302(2), multifamily residential developments are permitted in high density residential

          districts (R1) only as Type A Planned Residential Developments.

c.       Under § 312(4), multifamily residential developments are permitted in medium density residential

          districts (R2) only as Type A Planned Residential Developments.

d.      Under § 322(4), multifamily residential developments are permitted in medium density residential

          districts (R3) only as Type A Planned Residential Developments.

e.       Under § 332(4), multifamily residential developments are permitted in transitional residential

          districts (R4) only as Type B Planned Residential Developments.

f.       § 822.1 requires Type A Planned Residential Developments to have a minimum of five dwelling

          units.

g.      § 824.6 imposed mandatory open space requirements on Type A Planned Residential Developments.

h.      The five dwelling unit requirement is not applicable to Type B Planned Residential Developments

          (§ 822.2).

i.        Under § 825.4(3), the minimum lot area for a Type B Planned Residential Development that is

          connected to municipal water and sewer systems is 20,000 square feet.

j.        Development was assumed to occur as a Type B Planned Residential Development in a transitional

          residential district (R4) having a 20,000 square feet minimum lot size.

k.       20,000 square feet = 0.491 acres.

l.        Estimated BF/GF Trade-Off:  0.40:0.491 = 1:1.15.

3.       If constructed in the Town of Williston, Vermont:

a.       Authority:  Town of Williston, Vermont Zoning Ordinance (amended through April 30, 1998)

b.      Under the “Chart of Permitted and Conditional Uses” (§ 3.15), multifamily residential development

is permitted in the Taft Corners (TC) zoning district, is permitted as a Planned Residential Development in the Medium Density Residential (R) zoning district and the Mixed Use (MU) zoning district and as a conditional use in the Village Center (VC) zoning district.

c.       It is most likely that development would occur in either the Medium Density Residential (R) zoning

          district or the Mixed Use (MU) zoning district.

d.      Under § 3.16, Planned Residential Developments located in either the Medium Density Residential

          (R) zoning district or the Mixed Use (MU) zoning district have a minimum lot size of 6,000 square

          feet. 

e.       Also under § 3.16, the same setback requirements apply to both the Medium Density Residential (R)

zoning district and the Mixed Use (MU) zoning district with the exception of the front yard setback from roadways other than the principal town highways.  The setback requirement is 35 feet in the Medium Density Residential (R) zoning district and 50 feet in the Mixed Use (MU) zoning district.

f.       Because of the smaller setback requirements, development was assumed to occur in the Medium

          Density Residential (R) zoning district.

g.      Applying the setback requirements to the dimensions of the project resulted in a minimum area

          requirement of 7,750 square feet.

h.      The 6,000 square feet minimum lot size requirement noted above could not be used because it was

          less than the minimum area requirement resulting from the application of minimum setback

          requirements.

i.        7,750 square feet = 0.178 acre.

j.        Estimated BF/GF Trade-Off:  0.40:0.178 = 1:0.44.
