Document Description
An addendum to the Capistrano Bridge Fish Passage Project Initial Study/Mitigated Negative Declaration is needed to clarify a change in the third full paragraph on page 11-3 of the project description section of the Initial Study. This change in project description does not change the environmental analysis, or type or level of impacts contained in the Initial Study. The measures that have been incorporated into the project to minimize impacts on steelhead and red-legged frogs as listed in the Initial Study/Mitigated Negative Declaration will apply to this phase and the mitigation measures included to reduce hydrological impacts will also apply. This paragraph currently states: "City officials also have initiated restoration of an additional reach of San Pedro Creek, which extends from the eastern most limit of the current restoration project job (i.e., Linda Mar Convalescent Hospital) to the Peralta Street Bridge. This restoration is considered Phase III of the waters/wetlands ecosystem restoration of lower San Pedro Creek. Initial design is underway to lay back the south bank along this 1,300 ft. reach, remove non-native vegetation, widen the channel, and replant with native species in a plant community type complex identical to the lower restoration effort." This paragraph will be replaced by the following: "Removal of Pump Station at Convalescent Home The pump station and culvert along San Pedro creek at the Convalescent Hospital will be removed and the Convalescent Hospital's sewage drain system will be connected to the City's main wastewater system for the Linda Mar area. At this area, the creek has a steep bank (less than 2:1). This grade will be laid back to a minimum 2:1 grade to stabilize the creek after pump station is removed. The total extent of creekbank to be regraded would be about 300 feet long by about 40 feet wide. After the creekbank is regraded, it will be planted with a plant mosaic of appropriate plant species native to the creek as listed in page 11-5 of the Initial Study. The existing 48-inch storm sewage outfall pipe that goes to the pump station currently drains directly into the creek. This sewage pipe drains the drainage shed area, area roadways and the Convalescent Hospital parking lot. From the Convalescent Hospital, this existing sewer line will be redirected to the west along the new top of bank to an existing sewer main tie-in west of the hospital and across the creek. The new line will cross the creek. There are big stands of existing willows in this area which would be saved as an island, and a new overflow channel would be excavated between this island and the northern edge of the Convalescent Hospital property. This overflow channel will tie directly into the existing flood control channel just downstream (west) of the Convalescent Hospital property. The project will avoid affecting waters below the ordinary high water (OHW) mark with the exception of the removal of the storm drain. Storm drain removal will occur when the creek has receded enough for this area to be dry. The City is in the process of obtaining an easement from the property owner in exchange for fixing the sewer pump overflow problem. Approximately 1000 cy of dirt will be removed to lay back the creek (excavation). This dirt will be used in completing Phase 1 of the project. The appropriate plant species for this portion of creek and creekbank will be chosen from the seven plant community types as listed on page 11-5 of the Initial Study. These include: (1) Palustrine scrub-shrub community along the riparian corridor, dominated primarily by Arroyo and Sitka willows (Salix lasiolepis and S. sitchensis, respectively), with Red alder (Alnus rubra) also present; (2) Palustrine scrub shrub found primarily along the stream terraces, dominated primarily by Arroyo willow; (3) Palustrine scrub shrub community type planted along the steeper side slopes, dominated primarily by Arroyo and Sitka willows; (4) Palustrine forest along the riparian corridor, dominated by Red alder and Yellow willow (S. lucida subsp. lasiandra); (5) Palustrine forest dominated only by Red alder; (6) Palustrine emergent (persistent) planted along the creek margin, dominated by rushes and sedge (e.g., Scirpus microcarpus); and (7) Palustrine emergent (persistent along the slopes dominated by rushes (e.g., Juncus patens) that tolerate relatively drier site conditions."
