WADOHThis feature layer was created by the Mapping Inequalities Project at the University of Richmond and shows the Home Owners' Loan Corporation (HOLC) neighborhood ranking system, better known as redlining. Redlining shaped where money and resources were invested — and where they weren't — for many decades. These decisions created long-lasting environmental and health impacts that are still felt today, especially by historically minoritized communities and people with fewer financial resources. The grades created by the HOLC ranged from A to D. A was color-coded green, B - blue, C - yellow, and D - red. A (Best): Typically upper- or upper-middle-class white neighborhoods that HOLC defined as posing a minimal risk for banks and other mortgage lenders, as they were "ethnically homogeneous". B (Still Desirable): Generally mostly white, non-immigrant neighborhoods classified as "still desirable" and sound investments for mortgage lenders. C (Declining): Areas where the residents were often working-class and/or first or second-generation immigrants from Europe. These areas often lacked utilities and were characterized by older building stock. D (Hazardous): Areas here often received this grade because residents consisted of minority populations. These areas were more likely to be close to industrial areas and to have older housing. These maps are available for Spokane, Seattle, and Tacoma, which are the only cities in Washington where Home Owners Loan Corporation (HOLC) created redlining maps.
