the Puerto Rico Housing Authority, created by Gov. Luis Muñoz Marín and headed by Juan César Cordero Dávila, to consolidate several state and municipal housing agencies. Puerto Rico Housing and CRUV were responsible for the design and construction of many of the older "residenciales" in Puerto Rico. The first three public housing developments, Ponce De Leon, Santiago Iglesias and Caribe, are located in the city of Ponce. Henry Klumb provided early support for those efforts and one of his protégés, George McClintock was the first Architect-in-Chief of Puerto Rico Housing in the early-to-mid 1950s. Klumb's designs are the 1945 design work for the Cataño, San Lorenzo, Lares and Aguadilla Puerto Rico Housing projects, Naranjito Public Housing Project in 1957, Comerío Public Housing Project in 1958, and Residencial Las Virtudes, designed and built between 1969 ad 1976. Klumb had previously done work for several municipal housing agencies, including Mayagüez' and Ponce's. In 1973, José Enrique Arrarás became the first Secretary of Housing. He was appointed by Gov. Rafael Hernández Colón. In 1993, then governor Pedro Rosselló had the Puerto Rico National Guard doing security work at some of the public housing areas where crime, related to drug trafficking, was most prevalent. Since their construction, there have been many occasions when families are evicted en masse, and the buildings are demolished to make space for the erection of some new type of housing, that doesn't resemble "public housing". Organization As of 2020, there were 325 public housing developments in Puerto Rico under the Puerto Rico Public Housing Authority (PRPHA) and being managed by Management Agents. Operating funds are provided by HUD for tenant rent subsidizing and for the construction, acquisition, maintenance, and operations of public housing projects, which are in turn administered by several entities throughout the island called Public Housing Agencies (PHAs). The main Public Housing Agency in Puerto Rico is the Public Housing Administration (Administración de Vivienda Pública, or AVP, in Spanish) under the Puerto Rico Department of Housing (Departamento de Vivienda in Spanish). Other Public Housing Agencies include certain municipalities which are authorized by HUD and commonwealth law to operate housing projects independent of the main state PHA. All PHAs can contract a Management Agent (usually a for-profit enterprise) to manage the day-to-day operations, including processing tenant complaints, housing unit repairs, and overall project maintenance. HUD also allows private non-profit organizations and for-profit enterprises to manage housing projects as
