INTRODUCTION The property within the Eastlake Business Center II is located in the Telegraph Canyon Basin of the City of Chula Vista Wastewater Basins. The existing land use is commercial. The site is located at 830 and 831 Showroom Place. It is located approximately 1 mile east of SR 125. 2. OBJECTIVE The purpose of this study is to determine the impact of the subject development on the existing City of Chula Vista sewer system based on the City of Chula Vista Wastewater Collection System Master Plan (CCVWCSMP) dated May 12, 2014 by using existing and proposed sewage production factors. 3. METHODOLOGY This study compares existing flows based on Sewer Generation Rate from Overview of Sewer Service for Eastlake Business Center prepared by Wilson Engineering dated August 2, 1999 to proposed sewer flow based on City recommended Wastewater Duty Factors based on water demands by Land Use as shown on Table 3-2 of the CCVWCSMP. These Wastewater Duty Factors are based on projected flows. Also, according with CCVWCSMP Appendix 2 Page 77 of98 the existing 8" sewer main from MH No. 15128 to MH No. 15129 have the capacity to accept the proposed project flows since these existing pipelines have been checked by using projected flows. Attachment 1 depicts the subject parcels that comprise the project site which will drain to the existing 8" sewer main. The following is a list of these parcels: 595-710-11 &, 595-710-12 4.

CONCLUSION It has been shown by the this study that there is no increase in flow from the existing land use (Commercial) to the proposed land use (BC-4 Zone). Therefore no further analysis is required. 4 780 I Mission Center Court, Suite l 00. San Diego, California 92108 . (619)296-5565 . Fax (619)296-5564 ATTACHMENTS 1. Sewer Study Exhibit 2 .
