Model Development. This section describes the methods used to compile data for the hydrologic restoration evaluation. The goal of the hydrologic report is to conduct an evaluation on pre and post hydrologic conditions that will occur during the rehydration of the Breakfast Point mitigation area. The Breakfast Point primary stormwater management system (PSWMS) consists of connected series of natural creeks and ditched canals. Characteristic data was obtained from a new field survey, site visits, interviews, topographic and aerial maps. Survey locations and data are illustrated in Exhibits 3-1 and 3-2. For this study, the existing Breakfast Point PSWMS was represented with sixteen (16) hydrologic basins (storage) connected by thirteen (13) link (conveyance/structure) nodes. A nodal diagram is included in Exhibit 3-3. The nodes identified in the Breakfast Point PSWMS can be classified as either conveyance or storage elements. Conveyance elements include closed conduits, open channels, bridge crossings and road overflows that collect and route runoff through the system. Storage elements (basin nodes) include closed basins, natural depression areas that store and attenuate runoff within the system. Sixteen basins were delineated for this study and are identified in Exhibit 3-4 and represented with the symbols N-10 through N-160. Link structures (culverts, bridges, low areas) at basin outflows are also represented in Exhibit 3-4 and are labeled similar to L-071.
