To issue a Letter of Eligibility under 760 CMR 59.05(2), or a Letter of Approval under 760 CMR 59.05(4), DHCD must find that a proposed District satisfies each of the relevant requirements set forth in 760 CMR 59.04(1), and that no uncured Letter of Noncompliance has been issued to the Municipality under 760 CMR 59.07(3). Any area waiver request by a Municipality under 760 CMR 59.04(2) or any density reduction request under 760 CMR 59.04(3) must have been previously approved by DHCD under the procedure set forth in 760 CMR 59.05(6), no more than three years prior to the date of the 40R Zoning Application. DHCD may approve, disapprove, or approve with conditions, a request for the determination of eligibility for a District.
The 40R Zoning shall specify the minimum percentage of each Mixed-use Development that shall be devoted to residential use, which shall be no less than 51%. Zoning Incentive Payments for Mixed-use Developments shall be based on the applicable minimum residential density using the formula in 760 CMR 59.04(1)(d)1. Municipalities may mandate a certain percentage of commercial use in 40R Zoning as long as Mixed-use Developments meet the applicable minimum residential densities set forth in 760 CMR 59.04(1)(d)3. and 760 CMR 50.04(1)(d)4. as affected by the requirements set forth in 760 CMR 59.04(1)(d)1.
Example. A Mixed-use Development in a Smart Growth Zoning District is located on two acres of Developable Land (87,120 square feet) on which at least 40 Multi-family Residential units would be permitted if it were an entirely residential Project. The applicable Smart Growth Zoning requires a minimum residential density of 51% for Mixed-use Developments in the District.
Calculating the minimum number of residential units. If the Mixed-use Development were entirely residential, the minimum allowable density for the Project would provide for at least 40 Multi-family Residential units (two acres x 20 Multi-family Residential units). The applicable minimum residential density in this Mixed-use Development is 51%. A minimum of 21 residential units must be provided (40 residential units x 51% = 20.4, rounded up to the next highest integer).
In its 40R Zoning Application, the Municipality must also demonstrate that the District as developed at the proposed reduced density will be consistent with the Smart Growth goals set forth in M.G.L. c. 40R and 760 CMR 59.00. Approval of a density reduction will not be withdrawn by DHCD solely because, in a future census, the population of the Municipality exceeds 10,000.
