A landkreis cannot create TIRZ for economic development (z.B. infrastructure improvements around a new stadium), but a city can for this purpose create a TIRZ and increase to the borough.  Because federal and regional sources of rehabilitation are generally less available, local governments have been forced to find other ways to subsidize improvement projects in their communities without directly raising taxes. One of the instruments used by many states to deal with the slump due to a lack of federal and regional funds is the financing of tax assistance (TIF), a method of public funding used for more than 50 years for remediation and community improvement projects. Texas uses the TIF by creating Tax Reinvestment Zones (TIRZs) that can be initiated by the city or county or by a petition from homeowners whose overall holdings in the area consist of the majority of the assessed real estate value.  A TIRZ cannot be created without justification. As it stands, the region must have a detrimental influence on the economic future of the creative body. A Tax Increase Reinvestment Area (TIRZ) is a political subdivision of a municipality or county in the state of Texas, created to implement the funding of the tax increase. They can be initiated by the city or county or by a petition from owners whose total ownership in the area consists of a large part of the value of the land assessed. To obtain funding for a TIRZ area, applicants must complete three steps. There are three stages related to the creation of a TIRZ: [the sector must] severely stop or affect the healthy growth of the municipality or county that creates the area, delay the provision of housing or constitute an economic or social responsibility and pose a threat to public health, safety, morality or well-being in its current state and use…  However, this does not limit the use of TIRZ in poor areas. Among the conditions that justify the creation of a TIRZ is “the predominance of defective or inadequate landscaping of sidewalks or roads” and prosperous areas may be included in a TIRZ; Uptown Houston is a TIRZ.B.
