D.C. Mun. Regs. tit. 11, § 1708
1708.1 Two (2) or more lots may be combined for the purpose of achieving the required FAR equivalent for preferred uses as follows:
(1) Is signed by the owners of all affected lots;
(2) Runs with the land in perpetuity;
(1) The lots' eligibility to allocate residential and nonresidential uses;
(2) The accuracy of the computations with respect to the amount of required preferred uses allocated; and
(3) Whether, after the transfer, the combined lots will conform to the maximum and minimum gross floor area requirements on the lots before any such transfer.
1708.2 In accordance with 11 DCMR § 1706.13(b), a certificate of occupancy may be issued for nonresidential uses on a sending lot or lots that allocated required residential uses to a receiving lot, without regard to the status of the receiving lot, if:
(a) An escrow account is established with a financial institution, including a title insurance company, that is recognized to be in good standing by the District of Columbia or other jurisdiction in which it conducts business;
(b) The escrow account is funded in accordance with § 1708.3; and
(c) The following are attached to the combined lot development covenant recorded and filed in accordance with § 1708.1 (i):
(1) A certification by the financial institution of the amount of funds received;
(2) An acknowledgment by the financial institution that the funds will be disbursed only in accordance with the mandatory escrow terms in § 1708.5; and
(3) A copy of the agreement governing the escrow account.
1708.3 The escrowed funds shall be equal to the amount computed according to either the formula E = GFA (AV / LA) / NRFAR x 50%, or the formula E = GFA x $15, whichever is less. The values in these formulae shall have the following meaning:
(a) E = The amount deposited into escrow;
(b) GFA = The gross floor area of additional nonresidential uses that will be achieved on the sending lot as a result of the combined lot transfer, above that to which the sending lot would have been permitted as a matter of right, as measured in square feet;
(c) AV = The assessed value of the sending lot's land and improvements, as of thirty (30) days prior to the escrow funding date, as that value is indicated on the records of the Office of Tax and Revenue;
(d) LA = The number of square feet of land included in the sending lot;
(e) NRFAR = The permitted nonresidential FAR before the transfer; and
(f) 50% = The proportion of commercial value that has been determined to be appropriate for the escrow.
Illustration: A sending lot zoned DD/C-2-C wishes to transfer its entire residential requirement. The lot is 20,000 square feet in size. As a consequence of its DD/C-2-C zoning, the lot's permitted density is 8.0 FAR, of which at least 4.5 FAR (that is, 90,000 square feet of gross
floor area) must be devoted to residential uses. The lot's assessed value, as of 30 days prior to escrow funding, was $ 700,000.
Based upon this scenario, the following formula values apply: GFA = 90,000 sq. ft.; AV = $ 700,000; LA = 20,000 sq. ft.; and NRFAR = 3.5 (8.0 - 4.5 = 3.5 of permitted nonresidential FAR).
The escrow funding would be calculated under the formula E = GFA (AV / LA) / NRFAR x 50% as follows: 90,000 sq. ft. x ($ 700,000 / 20,000 sq. ft.) / 3.5 x 50% = $ 450,000. Under the E = GFA x $ 15 formula, the escrow would be calculated as follows: 90,000 sq. ft. x $ 15 = $ 1,350,000. Since the result of the first formula ($ 450,000) is less than result of the second formula ($ 1,350,000), the minimum escrow funding would be $ 450,000.
1708.4 Escrowed funds shall be invested in investment grade securities.
1708.5 The escrow account agreement shall include terms providing that:
(a) Upon certification by the project architect to both the financial institution holding the funds and the Zoning Administrator that construction of all the residential uses required for the combined lot are at least 50% complete on the receiving lot, the funds held in the escrow account shall be disbursed in accordance with the applicable terms of the escrow agreement.
(b) If the above certification is not made within five (5) years after the filing date of the combined lot development covenant, or such further period of time as may have been permitted by the Zoning Commission pursuant to § 1708.6, escrowed funds and any accrued interest shall be released to the District of Columbia Housing Production Trust Fund and designated for the financing of housing in the DD Overlay District in the same Housing Priority Area as the receiving lot. The escrow agent shall advise the Zoning Commission if the funds cannot be released in accordance with this provision and, in that event, shall release the funds as the Commission may thereafter direct, consistent with the purposes of this chapter.
1708.6 The owner of the receiving lot may request the Zoning Commission to allow an additional period, up to a maximum of three (3) years, to make the certification set forth in § 1708.5(a). The request shall identify why the certification could not be made within the five-year (5-year) period provided and be accompanied by a timetable for construction and occupancy of the residential uses required for the combined lot. The Commission may grant the request upon a showing that the owner has proceeded with due diligence and in good faith in constructing the required residential uses.
