Staff plans to bring the draft IPM Policy to the Board for approval in September 2010. i) Clea_ry Brothers Landscaping Blanket Potholing Contract - Performance Update At the December 17, 2009 Board meeting the Board of Directors awarded a non-destructive potholing contract to Cleary Brothers Landscaping. Staff was asked to provide an update on Cleary Brothers performance in July 2010. Cleary Brothers has performed well on the Diablo Renovations Phase 1 project and the Martinez Renovations Phase 3 project. Their production rate is about average while their hourly cost is lower than previous potholing contracts. They do a very good job on site cleanliness and traffic control. The Engineering Department is pleased with their work. Additional information is provided in a memorandum included in the Board package. j) Town of Moraga Street Lighting Assessment Increase Pursuant to a recent public hearing process, the Town of Moraga will levy increased assessments for Moraga Street Lighting Assessment District No. 1979-1. Each property in Moraga is assessed for the operation and maintenance of street lighting. The property upon which the Moraga Pumping Station is located was formerly exempt but is now subject to this assessment. The assessment will be $29 per year. k) Car Washing Services The District will be bringing in an organization to wash the District's vehicles that are parked in the main lot on the plant. This is scheduled to begin on July 8~h. This organization is Contra Costa ARC -Commercial Support Services (CSS). The vehicles will be washed onsite in the plant parking lot on Tuesdays and Thursdays. CSS provides vehicle washing services for other public agencies as well, such as Contra Costa County, CHP and the City of Antioch. Contra Costa ARC is a nonprofit community based membership organization which exists to enhance and enrich the lives of children and adults with developmental disabilities. They provide direct services and advocacy to assist those they serve in achieving their highest level of personal independence and self-sufficiency. Contra Costa ARC is known for providing high quality, cost-effective services, and they are a respected leader in the field. They serve over 1,000 children and adults in Contra Costa County every day, they are the largest employer of people with developmental disabilities in the county, and they are one of the largest providers of services to people with developmental disabilities in California. Portable standby engine-generators are a critical component of the Standby Power Facility Improvement Project. Replacement of the existing standby engines cannot occur until staff has verified the portables are a reliable back-up power system which can be available while the existing standby engine-generators are removed and replaced with the new engine-generators: On Saturday May 19t", 2010, while testing the portable standby engine- generators on full plant load, faulty relay wiring caused the entire plant to lose power. Since the cogeneration unit was off-line to enable the test by not requiring complex paralleling control logic, staff restored power via PG&E. Additional operations staff were on hand in case of potential problems, therefore the plant was without power for only approximately 3 minutes and major processes were back on-line within 1 hour. No violations of our Title V or NPDES permits occurred. After correcting the relay issue, staff successfully retested the portables on Wednesday June 23`d and can now proceed to replace the existing standby engine-generators with the new units. Agenda Item 6.a.2) Board Meeting of July 1 2010 Additional Written Announcements: ~roject/General Updates m) Diablo Sewer Renovation Phase 1 Public Worksho The District hosted a public workshop on Thursday, June 24 from 7:00 to 8:00 pm. at the Diablo Country Club. There were approximately 15 attendees, and the topics discussed were; expected construction impacts, paving and property restoration, and lateral reconnection. n) Environmental Documents to be Released for Public Comment Two environmental documents related to District annexations will be released this month for public comment. The Draft EIR for annexation of nine properties in the Alhambra Valley that are outside the Urban Limit Line will be released by July 12. A draft negative declaration for the proposed annexation of properties in the EI Toyonal area of Orinda (District Annexation No. 175) will be released in late July for public comment. Both documents could potentially generate significant comments by the public and/or public agencies. Public hearings for both documents before the Board of Directors are tentatively scheduled for September 16, 2010. o) Rodent Control on Treatment Plant An item in Contra Costa Times Gary Bogue's Pet & Animal column in todays edition (July 1, 2010) noted that CCCSD will begin a feeding program to reduce the number of ground squirrels on treatment plaht property. The article did not mention the District has been mandated by the Department of Water Resources/Dam Safety Division to reduce the existing squirrel population near the clearwell which stores the District's recycled water. The burrowing squirrels have damaged clearvvell walls and further damage could result in loss of recycled water and ultimately failure of the clearwell. District staff is researching options to a feeding program. If those options can not reduce the squirrel population enough to protect our recycled water system, we may need to resort to a feeding program for the needed results. DEPARTMENT OF THE ARMY U.S. Army Engineer District, Sacramento Corps of Engineers 1325 J Street REP~rro Sacramento, California 958142922 ATTENTION OF Flood Protection and Navigation Section (602-06) JUN 2 2 2010 Mr. Tim Jensen Contra Costa County Flood Control and Water Conservatioh District 255 Glacier Drive Martinez, California 94553-4825 Dear Mr. Jensen: 0 We have reviewed a permit application by Central Contra Costa Sanitary District (602-06). This project includes the installation of two parallel, 4 foot high by 10 foot wide rectangular box culverts through the left bank levee of Walnut Creek. The project is located just upstream from the Burlington Northern Santa Fe railroad tracks at 38.0144°N 122.0695°W NAD 83, Contra Costa County, California. The District Engineer has no objection to approval of this application by Contra Costa County Flood Control and Water Conservation District from a flood control standpoint, subject to the following conditions: a. That the levee section and levee roadway shall be restored to existing lines and grade. b. That the proposed work shall not be performed during the flood season from November 1 to April 15, unless otherwise approved in writing by your District. c. That the seepage cut-off collars indicated on the drawings shall not be installed. d. That the levee embankment shall be reconstructed with impervious material compacted to at least 95% of maximum density as obtained by standard Proctor tests (ASTM D 698) at a moisture content between -2 and +3 of the optimum moisture content. Material excavated for the pipe installation may be reused if the material is suitable for levee fill. e. That the conduit shall be of sufficient strength to withstand anticipated vehicle loading. f. That the applicant shall periodically inspect the slide gates to ensure they are functioning properly. -z- g. That the slide gates at the watenvard end of the levee shall be kept in the closed position except when bypassing water. The bypass shall only be operated when the water surface elevation in Walnut Creek is below, and forecasted to remain below, the invert of the culvert. h. That riprap shall be placed around the pipe outlet to prevent erosion. The riprap shall be placed on at least 6 inches of sandy filter material. i. That because the guardrail on top of the pipe headwall may accumulate debris, the guardrail shall not be installed. A Section 10 and/or Section 404 permit (2009-00125S) has been issued for this work. If you have any questions concerning our comments on these plans, please contact Mr. Ryan Larson at (916) 557-7568 or Mr. Robert Murakami at (916) 557-6738. Sincerely, :~M.,c~l..,~ .cP Michael D. Mahoney, P.E. Chief, Construction-Operations Division .a 0 Central Contra Costa Sanitary District June 23, 2010 TO: BOARD OF DIREC~}T~O;RS. VIA: JAMES M. KELLY/"' -~ ANN E. FARRELL(}~1~ ANDREW J. ANTKOWIAK~ FROM: MICHAELJ.PENNY~~ SUBJECT: PERFORMANCE OF CLEARY BROTHERS LANDSCAPING ON POTHOLING BLANKET CONTRACT Cleary Brothers Landscaping was the successful low bidder in December 2009 for the nondestructive potholing blanket contract at 55% of the second low bidder. Cleary Brothers had not done any previous potholing work for the District and there was some concern about their ability to adequately perform the potholing work. Cleary Brothers has since successfully completed two potholing assignments. The first was for the Diablo Renovations, Phase 1 project, consisting of seven potholes with an average depth of 7 feet at a cost of $815 per pothole. The second was for the Martinez Renovations, Phase 3 project, consisting of ten potholes with an average depth of 3 feet at a cost of $570 per pothole. The previous potholing contractor's (Exaro) average cost per pothole was $675. Nondestructive potholing typically involves jackhammering out a 1-foot square hole in the pavement, breaking up the soil/backfill with either an air lance or water jet to expose the utility, identifying the utility and pipe size, measuring the depth of the utility, backfilling and compacting the hole, placing an asphalt patch at the top of the hole, and sweeping up the site for cleanup. Cleary Brothers does a few things differently than previous contractors. Previous contractors have used a jackhammer to cut through road pavement. Cleary Brothers uses a 12-inch diameter hole cutter. This allows for better compaction during backfill/paving operations. They also have the ability to use either a standard air lance and vacuum for excavation or a water jet and vacuum. The air jet is good for excavating granular backfill and sand, the waterjet is good for excavating clay. With their ability to vacuum up water they pressure-wash the street after backfilling the holes, leaving the sites very clean. P:\CapitalProjects\Blanket Contracts\Correspondence\Cleary Bros Board Memo 6-24-10.doc Board of Directors Page 2 June 23, 2010 They have done a good job setting up traffic control around potholing sites. On busy streets they have brought in additional workers to flag traffic. Overall, the work has gone very well at a reasonable cost. Below are several pictures of their operations.
