In calculating the amount of supplemental funds provided by a grantee for purposes of paragraph (1), the grantee may include amounts from other Federal sources, any State or local government sources, any private contributions, the value of any donated material or building, the value of any lease on a building, the value of the time and services contributed by volunteers, and the value of any other in-kind services or administrative costs provided.
In using grant amounts under this section made available in fiscal year 2000 or thereafter for supportive services under paragraph (1)(L), a public housing agency may deposit such amounts in an endowment trust to provide supportive services over such period of time as the agency determines. Such amounts shall be provided to the agency by the Secretary in a lump sum when requested by the agency, shall be invested in a wise and prudent manner, and shall be used (together with any interest thereon earned) only for eligible uses pursuant to paragraph (1)(L). A public housing agency may use amounts in an endowment trust under this paragraph in conjunction with other amounts donated or otherwise made available to the trust for similar purposes.
An application for a grant under this section shall demonstrate the appropriateness of the proposal in the context of the local housing market relative to other alternatives, and shall include such other information and be submitted at such time and in accordance with such procedures, as the Secretary shall prescribe.
The Secretary may determine not to apply certain of the selection criteria established pursuant to paragraph (2) when awarding grants for demolition only, tenant-based assistance only, or other specific categories of revitalization activities. This section may not be construed to require any application for a grant under this section to include demolition of public housing or to preclude use of grant amounts for rehabilitation or rebuilding of any housing on an existing site.
Any severely distressed public housing disposed of pursuant to a revitalization plan and any public housing developed in lieu of such severely distressed housing, shall be subject to the provisions of section 1437p of this title. Severely distressed public housing demolished pursuant to a revitalization plan shall not be subject to the provisions of section 1437p of this title.
The Secretary may require a grantee under this section to make arrangements satisfactory to the Secretary for use of an entity other than the public housing agency to carry out activities assisted under the revitalization plan, if the Secretary determines that such action will help to effectuate the purposes of this section.
If a grantee under this section does not proceed within a reasonable timeframe, in the determination of the Secretary, the Secretary shall withdraw any grant amounts under this section that have not been obligated by the public housing agency. The Secretary shall redistribute any withdrawn amounts to one or more other applicants eligible for assistance under this section or to one or more other entities capable of proceeding expeditiously in the same locality in carrying out the revitalization plan of the original grantee.
The term “supportive services” includes all activities that will promote upward mobility, self-sufficiency, and improved quality of life for the residents of the public housing project involved, including literacy training, job training, day care, transportation, and economic development activities.
Of the amount appropriated pursuant to paragraph (1) for any fiscal year, the Secretary may use up to 2 percent for technical assistance or contract expertise, including assistance in connection with the establishment and operation of computer centers in public housing through the Neighborhoods  Networks initiative described in subsection (d)(1)(G). Such assistance or contract expertise may be provided directly or indirectly by grants, contracts, or cooperative agreements, and shall include training, and the cost of necessary travel for participants in such training, by or to officials of the Department of Housing and Urban Development, of public housing agencies, and of residents.
