That the City Council of the City of Redding hereby approves and accepts the settlement proposal of Pace Engineering as contained in its letter dated October 12, 1992, a true copy of which is attached hereto and incorporated herein by reference. 2. That the Mayor of the City of Redding is hereby authorized and directed to sign the City' s approval and acceptance on said letter on behalf of the City of Redding; and the City Clerk is hereby authorized and directed to attest the signature of the Mayor and to impress the official seal of the City of Redding thereto.

HAY , City Attorney i 1 r RACE C Pr Associated Consulting ENGINEERING Engineers Incorporated I� October 12 , 1992 1 20. 03 i �I P Bob Galusha, Director Department of Public Works City of Redding 760 Parkview Avenue II Redding, CA 96001 I Dear Bob: Subject: Clear Creek Wastewater Treatment Plant Bubble Trap Settlement Proposal i The purpose of this letter is to confirm our discussions regarding a settlement of our responsibility regarding the design of the bubble trap constructed at the Clear Creek Wastewater Treatment Plant. As you know, the bubble trap is not effective. We have indicated to you a willingness to pay for a significant portion of your loss. We also indicated we would like to work it out in the form of services. After much discussion between Steve Craig, and you and I, it appeared we had a compromise whereby the City would accept our ,i services for the preliminary design of a revised bubble trap 'i (which is submitted to you under separate cover) together with computer mapping of the sewer system in the Clear Creek Service Area, in lieu of its loss. This is summarized as follows: LOSS Construction Cost of Bubble Trap = $33, 800 J 'i GAIN �I II Preliminary Design of Revised Bubble Trap = $11, 392* Computer Mapping of Sewer System = $22 , 408 i $33 , 800 *A reasonable value for work performed t� %I 1730 SOUTH STREET • REDDING, CA 96001 0 (916) 244-0202 FAX (916) 244-1978 • 0 . Bob Galusha, Director October 12, 1992 Page 2 20. 03 i Attached is a scope of work for the computer mapping. Our costs for all the computer mapping on the Stillwater Project, including incidental expenses, amounted to $12 , 195. This cost did not include much of our learning time either which we billed to our own overhead. At least $10, 000 of this cost was for work that will similarly need to be accomplished on the Clear Creek system. Since the Clear Creek system has about 243 percent more manholes than Stillwater, a scale up cost for this Clear Creek work would be $24 , 300. This compares to our estimate, based on drafting time, of $22 , 408, which did not include any contingency allow- ance. 'I If you wish us to proceed, we will agree to perform the computer mapping pursuant to the attached scope of work, at no cost to the City, and in return, the City will release us from any further responsibility regarding the design and lack of performance of the bubble trap. If you agree to this, please acknowledge by signing and returning a copy of this letter, or if you wish you may want a more formal agreement incorporating the attached scope " of work. Hopefully this will resolve this matter to the complete satisfaction of the City. Please give me a call if you have any questions. Very truly yours, Larry�l. Kepple Managing Engineer WP-A/LGK/kbu enclosure Approved and Accepted: CITY OF REDDING By Date: �i i SCOPE OF WORK CLEAR CREEK WWTP SERVICE AREA GIS SEWER MAPPING Owner (City of Redding) will provide PACE Engineering floppy discs of the City's Geographical Information System (GIS) for the Clear Creek Wastewater Treatment Plant (WWTP) Service Area, to the limits of the current GIS mapping. Owner will also provide approximately 160 original 1"=200' scale, 11"x17" sewer atlas maps and a 1"=800' or 111-1, 000' scale map of the sewer system ii which shows the sub-service areas. 1. DIGITIZING SEWER SYSTEM I� 'N PACE will digitize the existing sewer system in the Clear Creek WWTP Service Area in special computer overlays as was done for the Stillwater Service Area. Digitizing will be done by first referencing the base sewer mapping with the GIS mapping. If any major discrepancies exist, the problem will be presented to the Owner for resolution. If the base maps are both compatible, or after adjustment instructions are received from the Owner, the sewer system will be digitized at every manhole, angle point, and end point. Curves will be input to match existing curves with reasonable accuracy. Following input, a hard copy print of the j sewer system at 1"=200' will be provided to the Owner for checking. There will be approximately 46 of these check prints to cover the existing sewer system. After correcting any errors, PACE will provide the Owner with a floppy disc of the sewer system mapping overlays including the corrections. !! The estimated cost for this task is $17 , 202 predicated on 381 hours of a CAD draftsman at $43 per hour plus 5% for incidental expenses. 'i !i 2 . DIGITIZING SUB-SERVICE AREAS Sub-service area boundaries within the limits of the current GIS � mapping g in will be digitized and input from the 1"=800' or 1"=1, 000', scale sewer plans as defined in the 1987 Master Plan along with any revisions made by the Owner since that date. The output of these areas will be reviewed by the Owner via the printouts provided in Item 3 . The estimated cost for this task is $2 , 980 predicated on 66 hours of a CAD draftsman at $43 per hour plus 5% incidental expenses. 3 PROVIDE SCALED DRAWINGS @ 111=1, 600' !' Provided 1111xl711 , 111=1, 600' scale drawings of the existing sewer system, similar to those provided in the Stillwater Master Sewer Plan, but without future improvements. To prepare these drawings n i SCOPE OF WORK CLEAR CREEK WWTP SERVICE AREA GIS SEWER MAPPING (continued) it will be necessary to add some street names and line sizes, as well as establish specific plot specifications. A minimum of it three copies of each will be provided to the City upon ii completion. Service subareas will be shown on these maps in color as was done in the Stillwater Master Plan. The estimated cost for this task is $1, 445 predicated on 32 hours of a CAD draftsman at $43 per hour. 4 . SUPERVISION & COORDINATION Additional costs will be incurred by the engineering manager in the supervision and coordination of this work. This is estimated at $781 based on eight hours at $93 per hour plus 5% for jI incidental expenses. I +� COST SUMMARY: 11 Task 1 $ 17, 202 Task 2 2 , 980 Task 3 1, 445 Task 4 781 l Total $ 22 , 408 5.
