The storage tank is generally the more economical option for this type of site. <br />DATE SIGNED: 06-19-2019 <br />Anth y J. Lopes, P.E., S.E. <br />,ik oF Es s 04, <br />< <br />N' <br />cfl <br />NO. 0-39729 <br />EXP. 12/31/19 <br />1611 <br />June 19, 2019 Page 2 of 2 <br /> ME SIEGFRIED <br />seepage pit (10— 60" pits) system will require an initial site area of roughly 75 ft. x 75 ft. or an <br />alternate layout of 45 ft. x 135 ft. A site must also be reserved for a future system 100% <br />replacement. Therefore, two independent areas are required or one combined area measuring 150 <br />ft. x 75 ft. (or 90 ft. x 135ft.) <br />The leach pits also require the following setbacks; <br />Property line —75 feet <br />Storm pond deeper than 6 feet — 100 feet (10 feet for ponds < 6 feet deep) <br />Onsite water wells - 150 feet <br />Buildings - 10 feet <br />6. Domestic and Fire Suppression Water <br />Offsite water services are not available at this site. The site can be served by a well and storage tank <br />system. A well exists onsite, however, the size, performance and viability of this well are unknown at <br />this time. <br />For domestic, potable use, State and County water quality standards must be met to utilize this <br />water system. <br />Based on our preliminary findings, in order to utilize an onsite water well for fire protection, one of <br />two alternatives must be provided; <br />An onsite well and back-up generator system capable of producing 1,500 gallons per minute <br />(gpm). <br />In accordance with NFPA 1142, an onsite storage tank with a 115,000 gallon capacity (for Type <br />VB Building) and associated fire pumping system capable of pumping 1,000 gpm. This is roughly <br />a 30 foot diameter by a 24 foot high tank. The tank size can be reduced to 77,000 gallons for a <br />Type IIIB building. <br />Stockton San Jose Sacramento Modesto <br />3244 Brookside Rd., #100 111 N.
