References: Supplemental Geotechnical Recommendations, La Costa Ridge Project, in the City of Carlsbad, CA, by PSE, dated January 16, 2006 (W.O. 401036) Gentlepersons: Preliminary Geotechnical Investigation, La Costa Ridge Project (Approximately 7+- Parcel), in the City of Carlsbad, CA, byPSE, dated Jthie 2;2005(w.o: 401036) C Presented herein is Pacific Soils Engineering, Inc.'s (PSE) response to a recent City of Carlsbad plan check review comment for the La Costa Ridge project. The comment concerns the distance between drainage swales and structures (see Plate 1, attached). r*4 Upon review of the comment and plan (Plate 1), it is our opinion that the distance between drainage swales and structures, as designed, is in accordance with our recommendations (References). Drainage swales may be located less than five (5) feet in horizontal distance away from structures as long as the structure footings are embddedbe1ow the elevations of the swale bottoms (PSE, 2005 Table 7.2). The drainage swales in question have only a 1.0% gradient and therefore the footing embedment depths will be significantly below the swale bottoms.
