—A—

Acquisition:  Acquisition means acquisition of standard housing only, with no expectation of other listed activities being carried out in conjunction with the acquisition.

Affordable Housing: Affordable housing is generally defined as housing where the occupant is paying no more than 30 percent of gross income for gross housing costs, including utility costs.

1.         Rental Housing: A rental housing unit is considered to be an affordable housing unit if it is occupied by a low-income family or individual and bears a rent that is the lesser of (1) the Existing Section 8 Fair Market Rent (FMR) for comparable units in the area or, (2) 30 percent of the adjusted income of a family whose income equals 65 percent of the median income for the area.  An exception is for those cases where, depending on the prevailing market conditions, HUD specifically establishes higher or lower FMR’s for a jurisdiction.

2.         Home ownership: Principal residence; and (2) has a sale price which does not exceed the mortgage limit for the type of single family housing for the area under HUD's single family insuring authority under the National Housing Act.

 (b)        Housing that is to be rehabilitated, but is already owned by a family when assistance is provided qualifies as affordable if the housing (1) is occupied by a low-income family which uses the housing as its principal residence and (2) has a value, after rehabilitation, that does not exceed the mortgage limit for the type of single family housing for the area, as described in 2(a) above.

Note:  these definitions apply for Consolidated Plan purposes, regardless of the Federal, State or local funding sources, i.e., even if the unit is not assisted with HOME funds.  Rental and home ownership projects assisted with Title II, HOME program funds are subject to "affordable housing" requirements, as contained in Section 92.252 (rental housing) and 92.254 (home ownership housing) of 24 CFR Part 92, which define "affordable housing" for purposes of the HOME program, unless otherwise noted.

AIDS and Related Diseases: The disease of acquired immune deficiency syndrome or any conditions arising from the etiologic agent for acquired immune deficiency syndrome.

Alcohol/Other Drug Addiction: A serious and persistent alcohol or other drug addiction that significantly limits a person's ability to live independently.

Area of Racial/Ethnic Concentration: The definition of Area of Racial/Ethnic Concentration is any area or Census Tract in the City of Redwood City where the ethnic classification of households exceed the citywide average of 10% for other than non Hispanic/white.

Assisted Household or Person: For the purpose of identification of goals, an assisted household or person is one which during the period covered by the annual plan will receive benefits through the Federal funds, either alone or in conjunction with the investment of other public or private funds.  The program funds providing the benefit(s) may be from any funding year or combined funding years.  A renter is benefited if the person takes occupancy of affordable housing that is newly acquired, newly rehabilitated, or newly constructed, and/or receives rental assistance through new budget authority.  An existing homeowner is benefited during the year if the home's rehabilitation is completed.  A first-time homebuyer is benefited if a home is purchased during the year.  A homeless person is benefited during the year if the person becomes an occupant of transitional or permanent housing.  A non-homeless person with special needs is concerned as being benefited, however, only if the provision of supportive services is linked to the acquisition, rehabilitation, or new construction of a housing unit and/or the provision of rental assistance during the year.  Households or persons who will benefit from more than one program activity must be counted only once.  To be included in the goals, the housing units must, at a minimum, satisfy the HUD Section 8 Housing Quality Standards (see 24 CFR section 882.109).  back to top

Lead-Contaminated Soil:  "Lead -contaminated soil" means bare soil on residential real property that contains lead at or in excess of the level determined to be hazardous to human health by the appropriate Federal agency.

Laboratory Accreditation: A laboratory that has been approved by a state to perform analyses of lead in paint and dust and whose approval is consistent with criteria established by the Environmental Protection Agency.

Lead-in dust: Interior house surface dust that contains an area concentration of lead that may pose a threat of adverse health effects in pregnant women or young children.  A hazard exists if concentrations exceed the Maximum Acceptable Standards: 200 micrograms per square foot (ug/sq.ft.) on floors, 500 ug/sq. ft on window sills, and 800 ug.sq ft. on window wells.

Replacement:  A strategy of abatement that removes components such as windows, doors, and trim that have lead-based painted surfaces, and installs new or de-leaded components free or lead-based paint.

Residential Dwelling:   (a) a single -family dwelling including attached structures such as porches and stoops; or (b) a single-family dwelling unit in a structure that contains more than 1 separate residential dwelling unit, and in which each such unit is used or occupied, or intended to be used or occupied, in whole or in part, as the home or residence of 1 or more persons.

Wipe Test: The testing of a surface for the present of lead dust by the patterned wiping of the surface, followed by analysis of the wipe by atomic absorption spectroscopy, giving the result in micrograms of lead per square foot of surface.  For clearance purposes, a sample of floors, windowsills, and window wells should be tested in accordance with HUD's Interim Guidelines.  The guidelines require that for clearance, all surfaces shall have less than the maximum allowance concentration standard of 200 ug/sq.ft. on floors, 500 ug/sq.ft on windowsills, and 800 ug/sq.ft on window wells.
