PZ - Geotech Report MATERIALS 6 April 2018 TESTI NG & Page# 1 of 27 INSPECTION b 180364g_hmitedgeo ❑Environmental Services ❑Geotechnical Engineering ❑Construction Materials Testing ❑Special Inspections Mr. Kameron Nauahi Brighton Development,Inc. 12601 West Explorer Drive, Suite 200 Boise, ID 83713 208-378-4000 Re: Limited Geotechnical Engineering Report Pinnacle Subdivision Near Locust Grove Road and Lake Hazel Road Meridian,ID Dear Mr. Nauahi: In compliance with your instructions, MTI has conducted a limited soils exploration for the above referenced development. Fieldwork for this investigation was conducted on 21 and 23 March 2018. The proposed development is in the southern portion of the City of Meridian, Ada County, ID, and occupies a portion of Sections 31 and 32, Township 3 North, Range 1 East, and Sections 5 and 6, Township 2 North, Range 1 East, Boise Meridian. This project will consist of construction of a residential subdivision. Details of the proposed subdivision are unknown at this time. MTI has not been informed of the proposed grading plan. Authorization Authorization to perform this exploration and analysis was given in the form of a written authorization to proceed from Mr. Jonathan D. Wardle of Brighton Development, Inc. to Elizabeth Brown of Materials Testing and Inspection (MTI), on 5 March 2018. Said authorization is subject to terms, conditions, and limitations described in the Professional Services Contract entered into between Brighton Development,Inc. and MTI. Our scope of services for the proposed development has been provided in our proposal dated 5 March 2018 and repeated below. Scope of Investigation The scope of this investigation included review of geologic literature and existing available geotechnical studies of the area, visual site reconnaissance of the immediate site, subsurface exploration of the site, field and laboratory testing of materials collected, and engineering analysis and evaluation of subsurface materials. Our scope of work did not include foundation design,pavement design, or earthwork recommendations. Regional Geology The project site is located within the western Snake River Plain of southwestern Idaho and eastern Oregon. The plain is a northwest trending rift basin, about 45 miles wide and 200 miles long,that developed about 14 million years ago(Ma)and has since been occupied sporadically by large inland lakes. Geologic materials found within and along the plain's margins reflect volcanic and fluvial/lacustrine sedimentary processes that have led to an accumulation of approximately 1 to 2 km of interbedded volcanic and sedimentary deposits within the plain. 2791 S Victory View Way•Boise,ID 83709•(208)376-4748•Fax(208)322-6515 Copyright www.mti-id.com•mti(@mti-id.com ght©Testing g&Inspection MATERIALS 6 April 2018 TESTI NG & Page#2 of 27 INSPECTION b 180364g_hmitedgeo ❑Environmental Services ❑Geotechnical Engineering ❑Construction Materials Testing ❑Special Inspections Along the margins of the plain, streams that drained the highlands to the north and south provided coarse to fine-grained sediments eroded from granitic and volcanic rocks, respectively. About 2 million years ago the last of the lakes was drained and since that time fluvial erosion and deposition has dominated the evolution of the landscape. The project site is underlain by"Gravel of Amity Terrace" as mapped by Othberg and Stanford (1993). The Amity terrace is the fifth terrace above the modern Boise River and represents the first level of Quaternary incision by the Boise River. The terrace, which has been correlated with Deer Flat terrace deposits to the west, is modified extensively by erosion and faulting. Where little erosion has taken place the terrace is mantled with loess 1.6-7 feet thick. General Site Characteristics This proposed development consists of approximately 426 acres of gently rolling terrain in the northwest to relatively flat and level terrain from the central to southeastern portion of the site. Throughout the majority of the site, surficial soils consist of fine-grained clay-sand mixtures. Vegetation primarily consists of agricultural crop remnants, bunchgrass, and other native grass varieties typical of and to semi-arid environments. The Farr Lateral trends northwest/southeast along the northern property boundary. In the central portion of the site, the McBimey Lateral trends west to east. The western and southern border of the site is bounded by the Rawson Canal. Regional drainage is north toward the Boise River. Stormwater drainage for the site is achieved by percolation through surficial soils. In the most northwestern portion of the property, intermittent off-site site stormwater may drain onto the site from the north. Stormwater drainage collection and retention systems are not in place on the project site and do not currently exist within the vicinity of the project site. Exploration and Sampling Procedures Field exploration conducted to determine engineering characteristics of subsurface materials included a reconnaissance of the project site and investigation by test pit. Test pit locations were predetermined by Brighton Construction and marked in the field. Test pit sites were located in the field by means of a Global Positioning System (GPS) device and are reportedly accurate to within ten feet. Upon completion of investigation, each test pit was backfilled with loose excavated materials. Re-excavation and compaction of these test pit areas are required prior to construction of overlying structures. In addition, samples were obtained from representative soil strata encountered. Samples obtained have been visually classified in the field by professional staff, identified according to test pit number and depth,placed in sealed containers, and transported to our laboratory for additional testing. Subsurface materials have been described in detail on logs provided in the Enclosures section. Results of field and laboratory tests are also presented in the Enclosures section. MTI recommends that these logs not be used to estimate fill material quantities. 2791 S Victory View Way•Boise,ID 83709•(208)376-4748•Fax(208)322-6515 Copyright www.mti-id.com•mti(@mti-id.com ght©Testing g&Inspection MATERIALS 6 April 2018 TESTI NG & Page# 3 of 27 INSPECTION b 180364g_hmitedgeo ❑Environmental Services ❑Geotechnical Engineering ❑Construction Materials Testing ❑Special Inspections Laboratory Testing Program Along with our field investigation, a supplemental laboratory testing program was conducted to determine additional pertinent engineering characteristics of subsurface materials necessary in an analysis of anticipated behavior of the proposed structures. Laboratory tests were conducted in accordance with current applicable American Society for Testing and Materials (ASTM) specifications, and results of these tests are to be found on the accompanying logs located in the Enclosures section. The laboratory testing program for this report included: Atterberg Limits Testing—ASTM D4318 and Grain Size Analysis—ASTM C 117/C 136. Soil and Sediment Profile The profile below represents a generalized interpretation for the project site. Note that on site soils strata, encountered between test pit locations, may vary from the individual soil profiles presented in the logs, which can be found in the Enclosures section. The materials encountered during exploration were quite typical for the geologic area mapped as Gravel of Amity Terrace. Surficial soils were predominately lean clays; though sandy silty clay and borderline lean clay/fat clay was noted in test pits 3 and 16, respective. Clays were brown to dark brown or grey, dry to moist, soft to very stiff, and contained fine to coarse-grained sand. In test pit 12, gravels were also noted within the lean clays. In test pits 6 and 7, surficial materials were silty gravel fills and sandy organic silt fill, respectively. The fills were brown, dry, dense/very soft, and contained fine to coarse-grained sand and fine to coarse gravel. Below the surficial soils throughout most of the site were silty sands. These sediments were brown to light brown, dry to moist, medium dense to very dense, and contained fine to coarse-grained sand. At depth in most test pits were poorly graded sand with silt, poorly graded gravel with sand, and poorly graded gravel with silt and sand. These sediments were brown to light brown to tan, dry, very dense, and contains fine to coarse-sand, fine to coarse gravel,and 12-inch-minus cobbles.Test pit 16 met with refusal on basalt.This basalt was blackish, slightly weathered to fresh, very closely fractured, very strong to extremely strong, and contained vesicles. Competency of test pit walls varied little across the site. In general, fine grained soils remained stable while more granular sediments readily sloughed. However, moisture contents will also affect wall competency with saturated soils having a tendency to readily slough when under load and unsupported. Groundwater During this field investigation, groundwater was not encountered in test pits advanced to a maximum depth of 16.7 feet bgs. Soil moistures in the test pits were generally dry to moist within surficial soils and dry below. In the vicinity of the project site, groundwater levels are controlled in large part by residential and agricultural irrigation activity and leakage from nearby canals. Maximum groundwater elevations likely occur during the later portion of the irrigation season. During previous investigations performed in March 2013 and November 2015 within approximately '/4-mile to the west and south of the project site, groundwater was not encountered to depths as great as 10.5 to 16.6 feet bgs. 2791 S Victory View Way•Boise,ID 83709•(208)376-4748•Fax(208)322-6515 Copyright www.mti-id.com•mti(@mti-id.com ght©Testing g&Inspection MATERIALS 6 April 2018 TESTI NG & Page#4 of 27 INSPECTION b 180364g_hmitedgeo ❑Environmental Services ❑Geotechnical Engineering ❑Construction Materials Testing ❑Special Inspections For construction purposes,groundwater depth can be assumed to remain greater than 15 feet bgs throughout the year. However,leakage from the laterals on or adjacent to the site may influence groundwater levels. Since this is an estimated depth and seasonal groundwater levels fluctuate, actual levels should be confirmed by periodic groundwater data collected from piezometers installed in all the test pits. If desired,MTI is available to perform this monitoring. Soil Infiltration Rates Soil permeability,which is a measure of the ability of a soil to transmit a fluid,was not tested in the field. Given the absence of direct measurements, for this report an estimation of infiltration is presented using generally recognized values for each soil type and gradation. Of soils comprising the generalized soil profile for this study, lean/fat clay soils and sandy silty clay soils generally offer little permeability, with typical hydraulic infiltration rates of less than 2 inches per hour. Silty sand sediments usually display rates of 4 to 8 inches per hour;though calcium carbonate cementation may reduce this value to near zero. Poorly graded sand and gravel sediments typically exhibit infiltration values in excess of 12 inches per hour; though calcium carbonate cementation may reduce this value to near zero. Infiltration testing is generally not required within these sediments because of their free-draining nature. Ada County Highway District (ACHD) will require onsite percolation testing once the proposed locations of infiltration facilities are determined. The quantity of testing will be dependent on the size and number of infiltration facilities planned, and can be determined from Section 8000 of the ACHD Policy Manual. The estimated infiltration rates listed above are to be considered preliminary and are only provided to determine feasibility for onsite infiltration.

Findings of this report are limited to data collected from noted explorations advanced and do not account for unidentified fill zones,unsuitable soil types or conditions,and variability in soil moisture and groundwater conditions. To avoid possible misinterpretations of findings, conclusions, and implications of this report, MTI should be retained to explain the report contents to other design professionals as well as construction professionals. Since actual subsurface conditions on the site can only be verified by earthwork, note that construction recommendations are based on general assumptions from selective observations and selective field exploratory sampling. Upon commencement of construction, such conditions may be identified that require corrective actions, and these required corrective actions may impact the project budget. Therefore, construction recommendations in this report should be considered preliminary, and MTI should be retained to observe actual subsurface conditions during earthwork construction activities to provide additional construction recommendations as needed. Since geotechnical reports are subject to misinterpretation, do not separate the soil logs from the report. Rather, provide a copy of, or authorize for their use, the complete report to other design professionals or contractors. Locations of exploratory sites referenced within this report should be considered approximate locations only. For more accurate locations, services of a professional land surveyor are recommended. This report is also limited to information available at the time it was prepared. In the event additional information is provided to MTI following publication of our report, it will be forwarded to the client for evaluation in the form received. Environmental Concerns Comments in this report concerning either onsite conditions or observations, including soil appearances and odors, are provided as general information. These comments are not intended to describe, quantify, or evaluate environmental concerns or situations. Since personnel, skills, procedures, standards, and equipment differ, a geotechnical investigation report is not intended to substitute for a geoenvironmental investigation or a Phase II/III Environmental Site Assessment. If environmental services are needed, MTI can provide, via a separate contract, those personnel who are trained to investigate and delineate soil and water contamination. General Comments Often questions arise concerning soil conditions because of design and construction details that occur on a project.
