<br /> project is not near the Pacific Ocean or on steep slopes,and any potential inundation from
<br /> seiche,tsunami, or mudflow is remote.
<br /> 5.15.3 Cumulative Effects
<br /> A cumulative impact refers to a proposed project's incremental effect together with other
<br /> closely related past,present,and reasonably foreseeable future projects whose impacts may
<br /> compound or increase the incremental effect of the proposed project (Public Resources Code
<br /> §21083; California Code of Regulations, title 14, § 15064(h), 15065(c), 15130, and 15355).
<br /> In July 2008, 72 projects2 were being processed with the San Joaquin County Building
<br /> Department. These projects were in Acampo,Escalon,Farmington,French Camp,Linden,
<br /> Lodi,Lockeford,Manteca,Ripon,Stockton, and Tracy. The types of projects included
<br /> residential projects such as new residences, additions and remodels to existing residences,
<br /> mobile home renovations,and pool construction; commercial projects such as
<br /> administration buildings,barns, and a riding arena;light industrial projects such as storage
<br /> buildings, spray booths, and warehouses; office projects such as building conversions and
<br /> tenant improvements;and institutional projects such as classroom relocation and facilities to
<br /> house animals (Raborn,2008).
<br /> A cumulative impact could occur if the LEC discharge to the WPCF combined with the
<br /> trucked in septic waste from the development applications in San Joaquin County exceeded
<br /> the WPCF's capacity. Septic waste trucked into the WPCF for disposal is typically from
<br /> residential land uses within the facility's service boundary,which includes unincorporated
<br /> county areas north of Eight-mile Road, south of the Sacramento-San Joaquin County line
<br /> (excluding Galt),east of the Delta boundary,and west of the foothills (Dell Karlin,pers.
<br /> comm.,2008). However,while the WPCF does accept trucked in septic waste from
<br /> unincorporated San Joaquin County lands,this amount is minimal compared to the facility's
<br /> capacity (Dell Karlin,pers. comm.,2008). Therefore,the potential for cumulative impacts of
<br /> the LEC project combined with other projects in San Joaquin County would be less than
<br /> significant.
<br /> In July 2008,21 projects were in various stages of progress with the City of Lodi. Most of
<br /> these projects are zoned residential,with a few office,mixed use,institutional,commercial,
<br /> and industrial projects proposed. New residential development includes approximately
<br /> 3,348 units (Bereket,2008). A cumulative impact could occur if the LEC discharge to the
<br /> WPCF combined with the discharge from the development applications exceeded the
<br /> WPCF's capacity.
<br /> Currently,the WPCF treats approximately 6.3 million gallons per day (2,299 million gallons
<br /> per year) of municipal wastewater from the City of Lodi (City of Lodi,2006). Table 5.15-11
<br /> shows the average influent flows to the WPCF between 2002 and 2005. New development is
<br /> projected to produce an average of 97 gallons per capita per day (West Yost and Associates,
<br /> 2001). Projected peak flows are shown in Table 5.15-12.While the WPCF was expanded in
<br /> 1992 to its current capacity of 8.5 million gallons per day,the plant's permitted capacity
<br /> remains at 7 million gallons per day. The plant is currently functioning at 75 percent of
<br /> design capacity, and 91 percent of permitted capacity.
<br /> 2 For the purposes of this discussion,San Joaquin County sorted its projects by project cost,and provided a list of the projects
<br /> costing$25,000 or more.
