Kingwood residents lobbied the Texas Legislature, asking for modifications to the state's annexation laws. In 1999 the legislature successfully passed amendments requiring annexing municipalities to develop plans for services provided to communities being annexed, and municipalities are required to provide a three-year planning period prior to official annexation to allow for public comment. The modified law allows for communities to use arbitration if the annexing cities fail to follow through with their service plans. The amendments do not affect prior annexations, including Kingwood's annexation. Some Kingwood residents expressed satisfaction that other suburban unincorporated areas including The Woodlands would not undergo the annexation that occurred in Kingwood.
