Latona School (1906) in Wallingford. Parks similarly define some neighborhoods. Madrona Beach and Cowen and Ravenna Parks were privately established to encourage residential development upon otherwise unusable land. The plan for Olmsted Parks fulfilled its goal and significantly influenced the character of neighborhoods around parks and playgrounds. East Phinney and West Meridian neighborhoods are sometimes called Woodland Park, as well as South Green Lake or North Wallingford for Meridian. Covenants and racial restrictions Housing covenants became common in the 1920s and were validated by the U.S. Supreme Court in 1926. Minorities were effectively limited to the International District and parts of some neighborhoods in south-east Seattle for Asian- and Native Americans; or the Central District for people of African ancestry, clearly defining those neighborhoods. Ballard – Sunset Hill, Beacon Hill, Broadmoor, Green Lake, Laurelhurst, Magnolia, Queen Anne, South Lake City, and other Seattle neighborhoods and blocks had racially or ethnically restrictive housing covenants, such as the following sample: No person or persons of [any of several minorities] blood, lineage, or extraction shall be permitted to occupy a portion of said property ... except a domestic servant or servants who may actually and in good faith be employed by white occupants. Further restrictions on conveyance (rental, lease, sale, transfer) were often included, effectively defining most of the neighborhoods in Seattle during the first decades after establishment. The Supreme Court ruled in 1948 that racial restrictions would no longer be enforced. The Seattle Open Housing Ordinance became effective in 1968. Although unenforceable, legal complications prevent the covenants from being expunged from property title documents. Wards and Little City Halls Seattle initially adopted a ward system; however, in 1910, this system was replaced by non-partisan, at-large representation. Variations on ward systems were proposed and rejected in 1914, 1926, 1974, 1995, and 2003 and convictions for campaign-related money laundering followed the 1995 campaign. Critics claimed that district-style elections of the city council would result in Tammany Hall-style politics. In 1973, inspired by Boston's model, Mayor Wes Uhlman's administration implemented a system of Little City Halls, where Community Service Centers (CSCs) assumed responsibility for coordinating municipal services. Uhlman's political opponents called the CSCs a thinly disguised ward system designed to promote Uhlman's reelection. CSCs became a setting for political arguments between the city council and the mayor; controversies over accountability, cronyism, and ward politics occurred in 1974, 1976, and 1988. In 1991 the CSCs were
