he Community Development Block Grant (CDBG) program requires that each CDBG funded activity must either principally benefit low- and moderate-income persons, aid in the prevention or elimination of slums or blight, or meet a community development need having a particular urgency because existing conditions pose a serious and immediate threat to the health or welfare of the community and other financial resources are not available to meet that need. With respect to activities that principally benefit low- and moderate-income persons, at least 51 percent of the activity's beneficiaries must be low and moderate income. For CDBG, a person is considered to be of low income only if he or she is a member of a household whose income would qualify as "very low income" under the Section 8 Housing Assistance Payments program. Generally, these Section 8 limits are based on 50% of area median. Similarly, CDBG moderate income relies on Section 8 "lower income" limits, which are generally tied to 80% of area median. These data are from the 2011-2015 American Community Survey (ACS).

DeprecatedUpdated for PY-2023 (effective March 1, 2023, to September 30, 2024). Deprecated October 1, 2024.What does the data represent?These are named polygons that follow block group boundaries that contain 51% or greater low-to-moderate income persons as published by HUD from 2011-2015 ACS data. That data has been superseded by data developed from 2016-2020 ACS data by HUD and published at https://services.arcgis.com/VTyQ9soqVukalItT/ArcGIS/rest/services/LMISD_layers/FeatureServer/4. Target areas primarily served residential areas, and each target area ideally could self-identify as the named community.Where were they located?Target Areas of Harris County fit within the Harris County Service Area, which was the unincorporated land of Harris County, Texas plus then-cooperative cities. Any portions of otherwise qualified block groups that extended into non-service area were excluded from the target area. This prevented “double-dipping” community development resource entitlements.How accurate are they?Block group boundaries in Harris County follow visual cues such as roadways and streams. Census Bureau linework attempts to delineate these bounding features but they are seldom more accurate than within thirty feet of ground truth.Full-service city boundaries determine whether an incorporated area is within the Harris County Service Area or the non-service area. These are updated roughly quarterly in the Harris County GIS Repository layer managed by the Harris County Appraisal District. Target areas have been updated each year using this data from the late autumn to the end of each calendar year.When were they collected?When HCCSD updated the Service Area and Target Areas of Harris County in the latter part of each Program Year, it uses the current HUD LMISD dataset and HCAD full-service city boundaries to perform the update. HUD publishes an updated LMISD dataset every year, but the data HUD analyzes to create these updates only changes when an additional five-year period of American Community Survey data has accumulated. Therefore the survey data reported in the HUD LMISD were collected from 4 to 8 years prior (PY2019) to as much as 9 to 13 years prior to publishing the results (PY2023). Unless a local income survey was conducted more recently between one and four years ago, each Program Year’s target area boundaries reflect LMISD block group information collected at least four to as much as thirteen years ago.Who collected them?Harris County Community Services Department (HCCSD) collected and Harris County Housing & Community Development (HCHCD) maintains Harris County Service Area and Target Area information. As representative of one of the largest urban counties in the U.S. and the largest in Texas, the Highest Elected Official in Harris County has delegated HCHCD to implement HUD-assisted community development activities on unincorporated land and on behalf of the cooperative cities. Cooperative cities are generally those of insufficient size to become entitled to HUD funds on their own, i.e. less than 50,000 population. Through 9/30/2024 Harris County maintained agreements with 12 cooperative cities, including: Deer Park, Galena Park, Humble, Jacinto City, Katy, La Porte, Morgan's Point, Seabrook, Shoreacres, South Houston, Tomball, and Webster in PY2023. Tomball ended its agreement 9/30/2024, thereafter becoming part of the non-service area.
