In summary,the soils investigation for the specific domestic wastewater disposal area for the Multipurpose Building has found the indigenous soils under this area to contain a comparatively high percentage of clay that possesses surprisingly favorable permeability and potentially significant denitrification characteristics. To take advantage of these favorable soil characteristics, Quick 4TM Infiltrator Chambers® are specified to create uniform effluent dispersal by using a duplex, alternating pump pressure dose system, through a dual filter bed arrangement. As discussed in the Primary Report, nitrate impact to the water table under the subject property was found to exceed the Maximum Contaminant Level (MCL) for nitrate in drinking water in 2003. The domestic well that will serve the project has not been drilled as of the date of this Report. Since this well must be designated as a public well, it will have to be monitored under EHD regulations. In the time since the September 2003 Report was completed, the EHD has established a "Requirements Checklist" for all the types of Studies they require to standardize and create uniformity between the Reports being submitted. Within the text of this Report, bolded Section (§) numbers are referenced at the beginning of an applicable Paragraph or Paragraphs, Appendix or Table of Contents that correspond with the EHD Requirements Checklist. Section Numbers referenced as SSS§, are sections applicable for the Soil Suitability Study Requirements Checklist. Section Numbers referenced as NLS§, are sections applicable for the Nitrate Loading Study Requirements Checklist. Other portions of text may also apply to other sections of the Checklists. The architectural firm of Hammel, Green and Abrahamson, Inc. (HGA) of Roseville, California are the architects for the project and Shack and Company of Tracy, California are the civil engineers for the project. II. SOIL SUITABILITY STUDY FINDINGS A. S CT PROPERTY AND SURROUNDING STUDY AREA INFORMATION SSS 1.1. a project site is located in the southwest corner of Valpico d Corral Hollow Roads. The erty is currently fallow agricultural land, consisting of a total 20.O01�cres, and has been fallow(not under agricultural production) for the past five years. _ Surrounding land use to the east of the project is, and has been for over three decades, in low density rural residential along Corral Hollow Road. As noted on the San Joaquin County Parcel Viewer Maps,the current surrounding land use is composed primarily of agricultural production land to the south and southwest. Directly to the north of the project is very low density rural residential housing and new high density housing within the City limits of Tracy. To the west are two, single family rural residential structures, and the Church of Latter Day Saints o The General Plan is Open Space/Resource Conservation(OS/RC) and the current zoning ' U 20 SSS4 1.2. As referenced in the Introduction, it is proposed to construct the Church Co in seve ries, which are illustrated on the attached Site Plan. The construction of the Multipurpose Building,which is the subject of this report, is Phase 1. Page -2- Chesney Consulting
