EXHIBIT 2 <br /> Santa Ana Blvd. Grade Separation <br /> shoofly tracks east of existing railroad tracks. Nine parcels will require full acquisition, three <br /> parcels will require partial acquisition, and ten parcels will require temporary construction <br /> easements. Due the preliminary nature of this study, individual property owners were not <br /> consulted to determine the extent of the impacts to their properties. Full acquisition of a <br /> parcel is assumed where the proposed shoofly or detour road will impact an existing <br /> building, otherwise, temporary construction easements are assumed. Refer to Attachment G <br /> for a breakdown of the right-of-way requirements. <br /> 5.6 Drainage <br /> The drainage designs for the preferred alternative of the project follows the current Orange <br /> County Hydrology Manual (1986) and City of Santa Ana engineering design standards. <br /> Generally, 100-year and 25-year storm water discharges will be studied for sump conditions <br /> and gravity/flow-by conditions respectively. <br /> The project site currently receives surface flows generally from northeast to southwest by <br /> means of street flow. There is an existing storm drain system consisting of a 24-inch <br /> reinforced concrete pipe (RCP) and catch basins at Santa Ana Boulevard near the existing <br /> railroad at-grade crossing that receives surface flow from the project site and offsite flows <br /> from north of Santa Ana Boulevard. The project site runoff then drains to Santa Ana Delhi <br /> Channel and eventually discharges to Upper Newport Bay and Lower Newport Bay. <br /> In the proposed condition, a pump station and new catch basins are proposed to collect <br /> runoff in the newly created sump along Santa Ana Boulevard. The outflow from the pump <br /> station will be discharged to the existing 24-inch drainage system along Santa Ana <br /> Boulevard west of the project limit. A portion of the existing 24-inch RCP conflicting with the <br /> proposed improvements will be removed and a drainage system will be reestablished <br /> between the existing drainage system and the pump station. It is noted that the exact <br /> location and configuration of the pump station will be determined in the next phase of the <br /> project as details of the SARTC Master Plan and Street Car Corridor become available. <br /> Tentatively, the pump station is located next to the Fuller Street cul-de-sac since this is the <br /> area least impact by future SARTC expansion. <br /> The drainage pattern at Santiago Street near the project is not anticipated to be changed; <br /> however, additional catch basins should be considered at the northeast corner of the Santa <br /> Ana Boulevard / Santiago Street intersection to reduce surface flow traveling toward the <br /> proposed sump. The street flow along Logan Street and Lincoln Avenue north of Santa Ana <br /> Boulevard will be captured by an at grade swale before the underpass. <br /> 5.7 Utilities <br /> Refer to Attachment H for exhibits showing existing and proposed utilities. There are <br /> numerous existing utilities within the project footprint. Based on field investigation, as-built <br /> plan research, and coordination with various utilities owners, the existing utilities are <br /> summarized below. <br /> City of Santa Ana: <br /> 12" waterlines: A 12" waterline runs east-west along the Santa Ana Boulevard. It ties <br /> into a 16" waterline to near the intersection of the Santa Ana Boulevard and Santiago <br /> Street and tees into a 20" waterline running north-south direction along the Fuller Street <br /> to the east. A 20" waterline continues to the east under Santa Ana Boulevard until it <br /> connects to the 16"waterline along Grand Avenue. <br /> PROJECT REPORT EQUIVALENT 10 <br />
