The proposed realignment of Telegraph Canyon Creek would be roughly parallel to the originally proposed alignment and the new segment would, at its furthest point, be approximately 300 feet south of the existing creek in the city of Chula Vista. The realigned channel would consist of a rectangular concrete channel upstream of Broadway Street to a point 700 feet downstream. The channel would then change into a covered concrete double box which would tie into the existing culverts at the Interstate 5 crossing. The existing natural creek would be the disposal site for the material excavated from the construction of the new channel segment. Construction will occur from July 1987 to July 1988. The proposed project has been designed to avoid or to minimize environmental impacts. The potential impacts of the total project are temporary, localized, and not considered to be significant to biological, noise, air, water, cultural, and aesthetic resources. It is my determination that impacts resulting from the proposed project will not have significant effects on the physical environment or the quality of the human environment, and that the preparation of an Environmental Impact Statement is not required. 2 APR 1987 DATE ~ D. FRED. BUTL , . 1.0 ?TT~ODUCTION This Supplemental Environmental Assessment (SEA) covers the proposed channel realignment of Telegraph Canyon Creek that will occur between July 1987 and July 1988. A Final Environmental impact Statement (FEIS) was prepared for the Telegraph Canyon Creek flood control project in July 1983. This report described and mitigated impacts that would result from the project. The original alignment of the channel would have bifurcated privately owned parcels, thus making part of the property inaccessible to the owner. The new channel would be aligned on the border between properties, thus less land would have to be acquired. The proposed action would reduce Right of Way costs and impacts. This project is authorized by Section 205 of the 1948 Flood Control Act, as amended, (PL 80-858). 2.0 PROJECT DESCRIPTION The proposed realignment would be roughly parallel to the originally proposed alignment and the new segment would, at its furthest point, be approximately 300 feet south of the existing creek between Moss Street and Arizona Street. The realignment would encompass land approximately 200 feet east of Industrial Avenue to approximately 200 feet east of Broadway Street (Figure 1). The newly excavated and realigned channel would consist of a rectangular concrete channel upstream from Broadway Street to a point 700 feet downstream. The channel would then change into a covered concrete channel double box which would tie into the existing culverts at the Interstate 5 crossing. The existing natural creek would be the disposal site for the material excavated from the new channel. This material would consist of natural earth, stone, and organic material. The channel would be 25 feet wide and deep with a total width, including access roads, of 55 feet. All other aspects of the project are exactly the same as described in the 1983 FEIS. 2.1 ALTERNATIVES. .~--- ___ a. No Action. The No,Action alternative would align the channel as proposed in the 1983 PEIS. If the No Action alternative is chosen, Right of Way~nd construction costs would be higher than with the prop6Sed'project. 3.0 AFFECTED ENVIRONMENT. Refer to the FEIS for a description of biological resources, threatened and endangered species, cultural resources, air and water quality, noise, aesthetics and recreational resources that would be affected by the proposed channel realignment. Biological resources in the project area are of limited value. 3.1 THREATENED AND ENDANGERED SPECIES. On April 11, 1986, a letter was sent to the U.S. Fish and Wildlife Service requesting a list of threatened and endangered species in the proposed realignment area. No threatened or endangered species are present in the project area. FWS concurredin a letter dated May 14, 1986 (see Appendix A). CHANNEL ~E--.ALJGNME. i, // PROPOSED REALIGNMENT: ,, ".'~"',...;y,-~ ~-~ .'.~' '~ ,, ./ ~ ~"/.~,, / Figure 1. / CITY OF CHULA VISTA SAN DIEGO COUNTY 3.2 LAND USE. The project area is divided into small parcels, each of which is privately owned. Land use in the area is primarily urban; it consists of residential areas, a parking lot, light industry, and open fields. 3.3 PUBLIC HEALTH AND SAFETY. The project area is now used informally as a play area for children. 3.4 CULTURAL RESOURCES. A records search and in-field inspection completed for the project in May 1986 resulted in negative findings. The Corps has determined that the proposed project would not involve National Register or eligible properties. SHPO concurred in a letter dated 30 June 1986 (see Appendix A). 4.0 E~IVIRONMENTAL EFFECTS. The purpose of this SEA is to address the channel realignment of Telegraph Canyon Creek. Potential impacts on air quality, noise and aesthetics, recreation, and biological resources would be the same as those already discussed in the FEIS. Impacts on biological resources would be very limited. 4.1 THREATENED AND ENDANGERED SPECIES. There would be no impacts to threatened or endangered species in the Telegraph Canyon Creek project area. FWS concurred with this finding in a letter dated 14 May 1986 (see Appendix A). 4.2 LAND USE. The environmental effects on land use would be the same or similar as those discussed in the FE!S, except that less land would need to be acquired for the project. By realigning a segment of the channel there would be a reduction in the impacts to property owners because less of their property would be acquired, hence more of their property would be accessible to them. 4.3 PUBLIC SAFETY AND HEALTH. Since the old channel would be filled in with the material excavated from the new channel, there would be no public health or safety hazard remaining as a result of the construction. 4.4 CULTURAL RESOURCES. There would be no impacts on cultural resources. SHPO concurred with this finding in a letter dated 30 June 1986 (see Appendix A). 4.5 WATER QUALITY. .There would be no adverse impacts to water quality. The attached 404(B) water quality evaluation in Appendix B addresses the filling in of the old creek with the material excavated from the new channel. All other aspects regarding water quality are the same as described in the 1983 FEIS. 5.0 COORDINATION. DUe to the limited scope of the change in the project and the resultant lack of impacts, it was dete~ined that-- only limited coordination was necessary. During informal coordination no concerns were expressed. See coordination records in Appendix Ao 6.0 COMPLIANCE WITH ENVIRO~MENTAL REQUIREMENTS. This document has been prepared in accordance with the following laws and regulations: Clean Air Act. Clean Water Act. Coastal Zone Management Act. Endangered Species Act. Estuary Protection Act. Executive Order 11988, Floodplain Management. Fish and Wildlife Coordination Act National Environmental Protection Act. National Historic Preservation Act. Rivers and Harbors Act. 7.0 CONCLUSION. This SEA has addressed possible impacts as a result of a realignment of a portion of Telegraph Creek. Refer to the July 1983 FEIS for a complete description of the entire project and its alternatives. The realignment of a portion of Telegraph Creek is not expected to result in significant impacts to the physical or human environment. ' 8.0 LIST OF PREPARERS AND REVIEWERS.

The proposed channel realignment study area is located approximately 300 feet south of the existing creek and no rth of and parallel to Moss Street (enclosure 1). The project area was examined b7 Marie Cottrell, Los Angeles District Staff Archeologist, to determine whether the project would involve cultural or historic properties (enclosure 2). The records search and in-field inspection completed for the project resulted in negative findings. Based on the information provided in enclosure 2, the COE has determined that the proposed project will not involve National Register or eligible properties. Questions regarding this evaluation may be referred to Marie Cottrell at (213) 894-0237. If you agree with the evaluation, we would appreciate your concurrence. We understand that in accordance with 36 CFR 800.5(b), we may expect a response within 30 days. Sincerely, Carl F.

On 15 May 1986, Marie Cottrell, COE Staff Archeologist completed a field reconnaissance of the proposed Telegraph Canyon Channel Realigrment Study Area. (enclosure 1). The reconnaissance study was completed for in an Environmental Assessment being prepared by LAD for the project. 2. The study area is located wizhin the city of Chula Vista, San Diego County, Califoroia. It is located approximately 300 feet south of the existing creek and north of and parallel to Moss Street (enclosure 2). The proposed channel alignment extends from approximately 100 feet east of Broadway in a westerly direction to Interstate 5 which borders the project area on the west. 3. An in house records search indicated that there were no prehistoric sites officially recorded in the project area. A complete records search was performed i n 1975 by Dr. L. Leach of San Diego State University. The records and literature search was augmented by a walk-over survey and resulted in negative findings. Due to its location, however, it was felt that the area could be sensitive for buried archeological resources (Leach 1975). As a result COE contracted with Westec Services, Incorporated in 1978 to complete a backhoe testing program in the area a long the creek (Eckhardt 1978). The results of the backhoe test were negative. 4. In 1984, Gloria Lauter of LAD inspected the project area. Contact at that time with the Museum of Man indicated that they had no sites recorded within the project area. A field i nspectio n indicated that almost all of the proposed study area, except a vacant lot bounded o n the north by the proposed channel and on the south by Moss Street, was covered by asphalt or development. 5. On I5 May 1986 Marie Cottre!l inspected the area. The vacant lot, noted in 1984 as the only remaining open space i n the project area, was found to have recently been developed into an apartment complex. No unpaved or undeveloped areas currensiy exist in the study area. No cultural or historic properties were noted in the study area. SPLPE~RP 29 May 1986 SUBJECT: Archeological and Historic PrOperty Assessment of the Proposed Telegraph Canyon Flood Control Channel, City of Chula Vista, San Diego County, California 6. Based on the negative findings of the previous records searches and backhoe tests, it appears unlikely, given the highly disturbed nature of the area, that any historic or prehistoric properties are present in the study area. The proposed project should have no effect on cultural resources.
