Existing storm sewers vary in size from 12" to 36" in diameter. Most drainage facilities are comparatively small and due to the generally flat slopes, have limited capacity. Although maps with pipe sizes were provided by the city, pipe elevations are not available and thus a detailed capacity analysis is not possible. Existing system capacities were noted in the previous Carter Burgess study for some locations and existing capacities were estimated in critical areas based on surface grades. A more detailed evaluation of existing system capacity should be conducted during final design and prior to construction to verify any assumptions. Identified Drainage Problems The drainage problem areas evaluated with this study were determined from several sources. As part of the previous Carter Burgess study, problem areas were identified for the following locations: 1. Clayton Street in the downtown commercial area. This area has experienced frequent flooding streets with excessive ponding in the streets and flooding of adjacent buildings and basements during storm events. 2. Sunset Addition (referred to as Emerson Street and Sunset Park in the previous Carter Burgess study). This area also experiences frequent excessive street flooding and occasional flooding of adjacent residences. The existing Sunset Park retention pond has frequently filled up to, or close to its maximum capacity and contributes to a reduced capacity of the existing storm sewers in streets in the area.
