LOC.: 5007 The above-referenced project has been reviewed by this office. 1. SEWER SERVICE AVAILABILITY AND GENERAL DISTRICT REQUIREMENTS 1.1 The project site is within the CCCS1D sphere of influence, but annexation is necessary before sewer service can be provided. Annexation will require the approval of both the CCCSD Board of Directors and the Local Agency Formation Commission (LAFCO). This issue must be addressed during the CEQA process. 1.2 The plans submitted for District review do not show the I proposed project sewers. The developer should be aware that District policy requires gravity sewers in preference to pumped systems and the location 'of public sewers in public streets rather than in off-street locations to the extent possible. Variances from this policy are discouraged. However, the District will consider alternatives on a case-by-case basis where the project engineer justifies such alternatives to the District's satisfaction. Re�-ded Peter IiOB R.P. Page 2 December 8, 1992 1.3 Specific requirements are: Gravity Service. Sewers are to be designed to operate under gravity flow to the District's existing sanitary sewer system. 'The use of sewage pumps for individual lots will not be permitted unless it is economically impractical to construct a main sewer to provide gravity service. Section 4-01 .A.10.b of the District's Standard Specifications, 1986 Edition, provides criteria for allowing the use of sewage pumps at individual lots. Location in Streets. As a minimum, an 8-inch public sewer must be extended by the developer to serve each parcel (residential or commercial lot, townhouse unit, condominium building, or apartment complex, as appropriate). New sewer systems are to be designed with the maximum ,amount of public sewers located in streets. If public sewers proposed for this project are to be located in an off-street location, the project engineer must justify such location to the satisfaction of the District. Easements. An exclusive public sewer easement must be established over the alignment of each public sewer in an off-street or private street location to provide access for future maintenance. The following criteria are used to determine the public sewer easement width: • The sewer easement width shall be 15 feet where the public sewer is less than 12 inches in diameter and the depth is 9 feet or less. • The sewer easement width shall be 20 feet where the public sewer is 12 inches and larger in diameter or the! depth is greater than 9 feet. • If new public sewers are being installed across properties where existing improvements will remain in place adjacent to the new public sewers, sewer easement width may be reduced at the discretion of the District, but in no case can the width be less than 10 feet. In addition, all-weather access for the District's maintenance vehicles to all manholes and rodding inlets in off-street locations is required. All-weather access typically consists of a 10-foot wide cross section with a surface course of turf-block, 2 inches of asphalt concrete, or other equivalent all- R.P. Page 3 December 8, 1992 weather surface acceptable to the District, over 6 inches of aggregate base. The use of sanitary sewer easement surfaces shall be limited to paving, shrubbery, gardens, and other landscaping, excluding trees. Parallel surface drainage ways and permanent structures including, but not limited to, buildings, swimming pools, decks, and retaining walls are not permitted within the easement area. 2. SOURCE CONTROL REQUIREMENTS The District has reviewed this project for source control requirements. Base wastewater flow from this project appears to be domestic wastewater such as from residential, office, or church sources. Specific source control requirements are normally not applicable to domestic wastewater. However, materials such as gasoline, oil, sand, paint, pesticide residues, or other toxic substances are prohibited from being introduced into the District's sewer System. 3. SEWER CAPACITY The District has completed a limited analysis for the sewer system downstream of the proposed project. This analysis consisted of a review of District records for capacity deficiencies and a determination that the proposed project will generate less wastewater than our "trigger" for further analysis. The existing main sewer is adequate for the additional wastewater which will be generated by this project, but District facilities farther downstream do not have adequate flow carrying capacity under the District's current design criteria for ultimate conditions. Improvements to correct the deficiencies are in the District's Capital Improvement Plan. Improvements to the District's existing facilities that are required as a result of new development will be funded from applicable District fees and charges. The developer will be required to pay these fees and charges at the time of connection ,to the sewer system. 4. PRIVATE SEWERS The proposed project includes side sewers. A side sewer is defined as a private sewer which is owned and maintained by the.property owner and which connects the plumbing system of the building to the main sewer. The side sewer begins at the point of connection to the building plumbing system 2 feet outside the foundation line or building wall and terminates at the point of connection to the main sewer. District policy requires that the developer be responsible for installation of the side sewer,and the property owner be responsible for operation and maintenance of the side sewer. District review of the design and inspection of the work on the side sewer shall in no way constitute our acceptance of any responsibility for R.P. Page 4 December 8, 1992 maintenance or damage to property due to construction and subsequent operation and maintenance of the side sewer. The design intent of the typical side sewer details included in the CCCSD "Standard Specification," 1986 Edition, and presented in Sections 32-43 through 32-48 inclusive, is to reduce the amount of rainfall and groundwater that will infiltrate the,sewer, thereby avoiding unnecessary pumping and treatment costs. The typical side sewer details are not intended to meet the geotechnical, structural, or drainage requirements of special situations. 5. HILLSIDE AND CREEK AREA POLICIES The District has a Hillside and Creek Area Sewer Policy which addresses the design and installation of sewers in hillsides or unstable areas. The requirements of this policy must be followed' when construction plans are prepared. For your convenience, a copy of the policy is enclosed. The Sanitary District must review and approve any construction plans involving work on the public sewer system prior to the developer's applying for a building permit. The District's Permit Section will receive and process the construction plans. Sincerely, Russell B. Leavitt Planning Assistant RBL/ls Attachment c: Jonathan Sing Lee 830 Northgate Road Walnut Creek, CA 94598 CENTRAL CONTRA COSTA SANITARY DISTRICT PROCEDURES TO BE FOLLOWED -FOR DESIGNING SEWERS TO BE LOCATED IN HILLSIDE AND CREEK AREAS 1. Soils reports will be required where: a. Slopes of hills - where sewers are proposed for installation exceed IS percent. b. Sewers are proposed for installation within fifty feet of creekbeds. C. Sewers are proposed for installation within the range of influence of a possible landslide from adjacent hill . do Sewers are proposed for install-ation in historical slide locations. 2. A soils report prepared by a registered Civil Engineer practicing In Geotechnical Engineering must be submitted by the job engineer which covers the proposed -project. 3. If the project geotechnical report provided does not cover an off-road sewer alignment, the District may require a supplementary report. This report, at a minimum, must address the following: a. Supplementary geological setting, general. soils and bedrock conditions along the proposed sewer alignment, and recommended set backs from slides and creeks. b. Stability or instability of selected sewer alignment. C. Potential ground water problems. do Effect of trenching on slope stability (negative impacts on slope). e. Special backfill, special trenching requirements, or special supports that may be recommended. f. Erosion potential of soils around sewer near water courses. go Recommended corrections if an instability exists or may develop. 4. Installation of sewers in unrepaired slide areas is to be avoided. a. If an acceptable gravity route is feasible around the unrepaired slide, the sewer must be installed around the slide. b. If the only feasible gravity route is through a slide area, a complete study of the slide must be made by a Geotechnical Engineer. The Geotechnical Engineer must: propose a solution which is satisfactory to-the--District. -The normal solution is---- the s---the repair of the slide. C. If a satisfactory gravity solution does not exist, the pumping of sewage from individual homes will be considered. 5. The Project Engineer must furnish a map which shows existing creeks or swales which may convey water in the vicinity of any proposed sewer main alignments. 6. Sewers shall not be designed to be located in the bottom of swales or creeks. 7. For sewers which will be parallel to swales or creeks, the sewer must be designed far enough away from the drainageway to eliminate the possibility of future eroding around the sewer. A Geotechnical Engineer shall review the proposed alignment and furnish recommendations regarding long-term erosion potentials. a. If it is unfeasible to locate sewer mains on the downslope side of future homes and maintain a safe distance from drainage ways, consideration will be given to installing the sewers in street areas which may result in the installation of residential sewage pumps on individual .homes. 8. For sewers which cross creeks or swales, the crossing shall be as .nearly perpendicular to the drainageway as feasible. a. Bank and bottom protection shall be designed per the recommendation of a Geotechnical Engineer and shall . be_ installed in the drainageway as a part of the overhead or underground crossing. b. The Project Engineer shall pay particular attention to designing adequate support foundations and protection for the foundation. 9. An access easement (minimum width of ten feet) shall be granted by the developer from the nearest public street to the creek crossing structure along the route of the sewer main, if possible, for future maintenance. 10. The attached design standards shall be used by the Project Engineer . when designing sewers in hillside and/or creek areas. l DESIGN STANDARDS APPLICABLE TO SEWERS WHICH ARE TO BE LOCATED IN HILLSIDE AND CREEK AREAS 1. Sewers to be installed across hillside slopes (generally parallel to contours) shall be ductile iron (no bedding) if the cross slope of the hill exceeds 25 percent. 2. Sewers to be installed parallel to defined creeks shall be located no closer than twenty feet from the top of the bank if the creek bank is defined; if not, no closer than thirty feet from the centerline of the creek. 3. Sewers to be installed parallel to defined creeks from twenty to fifty feet away from the top of the bank shall be ductile iron (no bedding) . 4. Manholes to be installed on either ends of creek crossings shall be located no closer than twenty feet from the top of the creek bank.
