HETHERINGTON ENGINEERING, INC.; Third Party Review, Proposed 8 Townhouse House Development, 341-3-47 Oak Avenue, Carlsbad, California, September 11, 2018 Gentlemen: Pursuant to your request and authorization, Strata-Tech, Inc., has prepared this response to reference (2). The comments will be presented in numerical sequence followed by our response: 1. The Consultant should review the project grading, improvement, and foundation plans, provide any additional geotecimical recommendations considered necessary, and confirm that the plans have been prepared in accordance with the geotecimicat recommendations. 1920 Pacific Avenue, #16060, Long Beach, CA 90806 STRATA-TECH,INC. U EDCDN S U LTANTS TMS Highland Investments, LLC 2 W. 0. 284018 GRS Response October 15, 2018 Response; Strata-tech, Inc. has reviewed the grading plans provided by the Civil for the project on 10-10- 2018. The grading plan is used here to plot geotechnical data from reference (1). It appears the plans are consistent with the geoteclmical recommendations from Strata-Tech, inc. The Consultant should provide a more detailed description of proposed development including grading, 3tru0ture5firnpr0verneat3, drainage, use, foundation type, estimated structural loads, etc. Response; The proposed development is an 8-unit townhouse project on a single lot. The approach is to grade the site after demolition of the existing structures and clearing the land. Grading will for the most part consist of excavation for the building pad and semi-subterranean parking (see grading plans) Scarification and compaction of the exposed excavation bottom shall be performed due to disturbances caused by the excavation process. Retaining walls are planned and shoring will be employec where adjacent structures are potentially undermined. Existing property line masonry walls not being removed shall be surveyed and a photo log made before any excavation or demolition commences. Attached find shoring design parameter calculations. The building will be supported on continuous footings as described in reference(1) structural loads are anticipated to to be on the order of 3kips/lineal ft for wall loads and 30kips for columns. The Consultant should provide a geotechnicaI map/plot plan utilizing the latest grading plan for the project to clearly show (at a minimum) a) existing site topography, b) proposed stmoth Wimprowernents c) proposed finished grades, and d) locations of The subsuthice exploration. STRATA - TECH,INC. ED C ON S U LTA NT S TMS Highland Investments, LLC 3 W. 0. 284018 GRS Response October 15, 2018 Response; See response one and attached geotechnical plot plan. 4. The Consultant should provide a discussion of regional geologic conditions and a general description of regional and local fhultin& Response; Regional Geology of San Diego County is divided into three distinct geologic areas: the Coastal Plain region, Peninsular Ranges region, and Salton Trough region. "The Coastal Plain region includes most of western San Diego County and consists primarily of Mesozoic crystalline rocks underlain by marine and non-marine sedimentary rocks. In this region, drastic land and sea fluctuations have preserved ancient marine rocks up to elevations around 900 feet and ancient river deposits up to 1,200 feet. The Peninsular Ranges region includes much of eastern San Diego County and consists primarily of plutonic rocks that formed from the cooling of molten magmas deep within the Earth's crust between 140 and 90 million years ago. Other sediments are now preserved in this region as marbles, slates, schist, quartzites, and gneiss deposits. The Salton Trough or Colorado Desert region includes the eastern third of San Diego County and is characterized by late Miocene-aged marine sedimentary rocks and Pleistocene- aged stream and playa lake deposits (Demérd n.d.). Locally Carlsbad is within the coastal portion of the Peninsular Ranges Geomorphic Province, a region characterized by northwest-trending structural blocks and intervening fault zones. Typical lithologies in the Peninsular Ranges include a variety of igneous, intrusive rocks associated with the Cretaceous-age (between approximately 65 and 135 million years old) Southern California Batholith (a large igneous intrusive body). In western San Diego County, batholithic rocks are often intruded into Jurassic-age (between approximately 135 and 195 million years old) metavolcanic and/or metasedimentary units, with these basement rocks locally overlain by Tertiary-age (between approximately 2 and 65 million years old) marine and non-marine sedimentary strata. Tertiary rocks in the western portion of the county are associated primarily with a number of sea level advance and retreat cycles over approximately the last 55 million years, including sedimentary units in Carlsbad and vicinity as described below. Topographically, the Peninsular Ranges Province is composed of generally parallel ranges of steep-sloping hills and mountains separated by alluvial valleys. More recent uplift and erosion has produced the characteristic canyon and mesa topography present today in western San Diego County, as well as the deposition of surficial materials including Quaternary-age (less S STRATA - TECH,INC. GE DC ON S U LTA NT S TIvIS Highland Investments, LLC 4 W. 0. 284018 GRS Response October 15, 2018 than approximately two million years old) alluvium, colluvium and topsoil. The geology in the Oceanside Quadrangle, in which the city is located. There are no active faults that run directly through Carlsbad. Additionally, the California Geological Survey does not include Carlsbad on its list of cities affected by Alquist—Priolo Earthquake Fault Zones. The nearest fault to the city is the Newport—Inglewood—Rose Canyon Fault, which runs offshore of the western edge of the city and is considered active .2 Other faults in the region include the Coronado Bank, La Nacion, Elsinore, Agua Caliente, and San Jacinto. Fault activity has the potential to result in ground shaking, which can be of varying intensity depending on the intensity of earthquake activity, proximity to that activity, and local soils and geology conditions. Carlsbad is located within a seismically active region, and earthquakes have the potential to cause ground shaking of significant magnitude. Although located near fault lines, Carlsbad lies within a medium-low probabilistic peak ground acceleration zone. Historic documents record that an earthquake centered either on the Rose Canyon or Coronado Bank faults struck San Diego on May 27, 1862, damaging buildings in Old Town and causing ground rupture near the San Diego River mouth. This earthquake is believed to have had a magnitude of about 6.0 based on descriptions of the damage it caused. The strongest recorded earthquake in the San Diego area was a magnitude of 5.3 on the Richter scale that struck on July 13, 1986, on the Coronado Bank fault, 25 miles offshore of Solana Beach. There have been several moderate earthquakes recorded within the Rose Canyon Fault Zone as well. On June 17, 1985, three earthquakes hit San Diego measuring 3.9, 4.0, and 3.9, respectively, and on October 28, 1986, a stronger earthquake with a magnitude of 4.7 occurred. 5. The Consultant should address the potential for site geologic hazards including: liquefaction, fault rupture, and tsunami potential. Response; Liquefaction, fault rupture and tsunami potential for this site are considered improbable. The site is located about 46' above sea level and separated from the ocean by a sea cliff and approximately a quarter mile inland from the sea cliff. A tsunami however credibly large is not likely to affect the site. Fault rupture for the site is also extremely remote given the absence of active faulting in City of Carlsbad. STRATA - TECH,INC. GE DC ON S U LTA NT S TMS Highland Investments, LLC 5 W. 0. 284018 GRS Response October 15, 2018 Liquefaction is also of very low potential. The site is underlain by shallow beach/dune sands resting on bedrock. The local gradient is east toward the railroad line and the tributary area between the sea bluff and project is small so the likelihood of a freatic surface developing beneath the site is very low so, liquefaction is not a significant concern. Historically, seismic shaking levels in the San Diego region, including Carlsbad, have not been sufficient enough to trigger liquefaction. The city has a low liquefaction risk; however, there are areas of the city that have a higher risk of liquefaction due to the presence of hydraulic soils or soils that are often saturated or characteristic of wetlands. These areas are limited to the immediate vicinity of the Buena Vista, Agua Hedionda, and Batiquitos lagoons. 6, The Consultant should provide the soil/bedrock descriptions (fill, teiace deposits, bedrock) and contact depths on the Record of Subsurface Exploration logs. Response; Refer to the attached revised test-pit logs. The Consultant should claiy the total depth of TP-2 (124eet stated in the text; IS. feet stated on the Record of Subsurface Exploration). Response; The actual depth explored is 15 feet. The Consultant should provide the appropriate laboratory test standards used for the shear strength and moisture-density testing reported.
