Box 2711 Los Angeles, CA 90053-2325 Attn: SPLCO-R RE: Proposed discharge of fill material into "waters of the United States" South Carlsbad Village Storm Drain/Sewer Line City of Carlsbad Please accept with this letter, application and supporting plans and documents for authorization to place fill material into identified "waters of the United States", pursuant to Section 404 of the Clean Water Act. These "waters" have been identified along a linear stretch of largely unvegetated drainage channel, which parallels the SDNR railroad tracks within the railroad right-of-way, in the urbanized section of the city of Carlsbad. The proposed project by the City of Carlsbad involves the installation of a storm drain and sewer trunk line within the area in which the "waters" drainage channel presently exists. This utility infrastructure is needed due to the fact that the existing drainage and sewer facilities are undersized, and in disrepair. A Wetland Delineation Report for the South Carlsbad Village Storm Drain Project, by Dudek & Associates, for the subject project is included in this application package. This report concludes that a total of 0.63 acres of "waters" will be impacted by construction of the project. Such level of impact necessitates notification of the ACOE of the proposed discharge. Mitigation for the impact is proposed through wetland revegetation of a proposed designed swale, as recommended by Dudek & Associates. Inasmuch as the proposed project is located within a highly urbanized area, we are not aware and do not anticipate any direct or indirect effect on endangered species or cultural resources. 1530 FARADAY AVENUE • SUITE 100 • CARLSBAD, CA 9200S • (760) 951-07SO • FAX (760) 931-5744 • planningsystems(a nctimes.net The District Engineer U.S. Army Corps of Engineers May 18,1999 ' Page 2 Please feel free to contact me if you have any questions regarding this application.

The project is located wholely within the San Diego Northern Railroad right-of-way (ROW). Proposed storm drain sizes will range from 54-inch RCP at the northern end of the line, to 84-inch RCP southerly of Chestnut Avenue. Sewer line sizes range from 42-inch to 48-inch RCP, with the smaller size located at the northern end of the project. Approximately 2,750 feet (the northern segment) of the utility installation area will replace an existing unlined, open dirt channel. This channel is presently vegetated primarily ruderal, weedy plants, but includes two small wetland communities totalling 0.08 acres. The entire length of this northern segment of the project has been determined to constitute "waters of the United States", as defined by the ordinary high water mark of the drainage. __ (Please refer to the Wetland Delineation Report by Dudek & Associates, April 19, 1999, included with this application. The proposed storm drain/sewer line project continues southerly for another 2,750 linear feet in which it does not affect Corps jurisdictional lands to the outfall at Agua Hedionda Lagoon. This outfall will involve placement of a new headwall structure (not within jurisdiction). This new headwall will replace an existing concrete channel which routes storm runoff directly into the lagoon, onto existing riprap, which recently sunk into the substratum, and necessitates replacement. This maintenance of the riprap will affect 0.007 of waters within the OHWM, designated as jurisdictional pursuant to the Wetland Delineation Manual (1987). Since this riprap replacement is considered maintenance however, no Corps permit for this portion of the operation is requested. Dudek & Associates conclude in the Wetland Delineation Report that impacts to Corps Jurisdictional lands total 0.63 acres as follows: Freshwater marsh 0.08 ac. Waters of the US 0.55 ac. TOTAL 0.63 ac. Dudek & Associates recommend that mitigation for the 0.63 acres of jurisdictional impacts be conducted via creation of 0.63 acres (1:1 ratio due to poor quality of existing habitat) in a swale which could be constructed over the top of the proposed utility lines. The swale could be constructed at 10 to 11 feet in width, with an average mean high water mark width at 8 feet. Dudek recommends planting this swale with salt grass (Disichlis spicatn), which would actually result in 0.67 acres of total mitigation area. The applicant has agreed to concur with this recommended mitigation program.
