Gather information from the Developer/Engineer regarding the proposed development. A Gity of Centro! Point Public Works Department Staff Report is not intended to replace the City's Standards & Specifications. Staff Reports are written in coordination with the City's Standards & Specifications to form a useful guide. The City's Standards & Specifications should be consulted for any information not contained in a Public Works Staff Report. The "General" section of this staff report is a broad representation of the City of Central Point's Standards & Specifications for construction. For specific criteria relating to individual projectsldeveloprnent the City's Standard & Specifications should be consulted. SPECIAL REQUIREMENTS The following items are specific Public Works infrastructure recommendations identified while reviewing the Tentative Plat for Beebe Wood Village. CITY OF CENTRAL POINT PUBL(G WbRKS 1.}EPAF7TM,ENT STAFF REPORT 4/3(3/2003 2 E'xisting Infrastructure: The Developer shall demonstrate that all connections to existing infrastructure (i.e. streets, water, sanitary sewer, storm drain systems, natural drainage systems, etc.) will not interfere with or provide for the degradation of the existing effective level of service or operation of current infrastructure facilities, and that the existing infrastructure facilities have either adequate capacities to accommodate the flows andlor demands imposed on the existing infrastructure as the result of the connection of the proposed development's infrastructure, or will be improved by and at the expense of the Developer to accommodate the additional flows andlor demands; while maintaining or improving the existing level of service of the affected facility, as approved by (as app{icable}, the regulatory agency, utility owner, andlor property owner involved. Street Layout/Section: It is the understanding of the Public Works Department that the Developer intends to construct a Private Street, including a connection to Oakview Avenue located near the easterly property boundary, and a future connection to Brookdale Drive located near the southerly property boundary. The Developer's engineer should consult the City of Central Point Standards & Specifications for construction regarding the requirements for street sections, street geometry, right-af-way width, curb & gutter, sidewalk, landscaping rows, wheel chair ramps, and all other necessary street design guidelines. Historically Fire District #3 has recuired a minimum of two points of access to local developments. Although a second point of access will be provided with the future construction of Brookdale Drive, the Public Works Department is recommending a temporary alternate point of access for emergency services. The Developer's engineer should coordinate with Fire District #3 to develop a suitable secondary access. Written approval from Fire District #3 will be required before final construction drawing approval. Attached: City of Central Point standard drawing far a Private Street {A-1D) Pulblic Utility Easements: The Public Works Department recommends caordinatian between the Developer's engineer and surveyor to create the necessary public utility easements for Beebe Wood Village and utility provisions relative to future development located to the south of Beebe Woad Village. Storm Drainage Infrastructure: Astorm drain connection for the proposed development exists in close proximity to the northern property boundary. This connection was stubbed-out far future development and is recommended by the Public Works Department as the point of connection to the existing City of Central Point storm drain system. The Developer's engineer shall develop a facility plan for the storm drain collection and conveyance system which provides for run-off from and run-on onto the proposed development, any future development on adjacent properties, and any areas deemed by the Gity that wilt need to tie- into the proposed development's storm water collection and conveyance system. Acknowledging Beebe Waod Village storm drain system will be a public system, operated and maintained by the City. Suitable easements for storm drainage infrastructure will need to be dedicated to the City for alignment, construction, and maintenance of the necessary crry ar' c~rvrRAL Por-vr PUf.3LIC WORKS D~PRRTME'NT STAFI* REPORT 4/30/2003 3 storm drainage infrastructure. An appropriate system will need to be designed to the City of Central Pont Public Works Department's Standards & Specifications for construction. Wa#er Sys#em. The minimum size far distribution lateral water mains in residential areas shall be 8-inches. The minimum size in multiple-dwelling, commercial and industrial areas shall be '12-inches except that in the sole discretion of the Public Works Department, 8-inch lateral lines may be allowed if flows meet domestic and fire protection needs in the area. Where fire demands or line losses might demand larger sized pipe, the Engineer will be required to submit hydraulic computations to support the use of 8-inch pipe, or to establish the size required. The City of Central Point Public Works Department is recommending two connections to the existing City of Central Point water distribution system. © A connection to the existing S-inch ductile iron water line located in a City of Central point utility easement near the northerly property boundary. © A connection to the existing S-inch ductile iron waterline located in Oakview Avenue near the easterly property boundary.

STREETS-LIGHTING- TRA FFI C Section 300 & 700 of the City's Standards & Specification should be consulted far complete details regarding streets, lighting, and traffic guidelines. Street designs shall consider the needs of people with disabilities and the aged, such as visually impaired pedestrians and mobility-impaired pedestrians. Every effort should be made to locate street hardware away from pedestrian locations and provide a surface fee of bumps and cracks, which create safety and mobility problems. Smooth access ramps shall be provided where required. All designs shall conform to the currenfi American Disabilities Act (ADA) ar as adopted by the Oregon Department of Transportation (ODOT), Oregon Bicycle and Pedestrian Plan, 2. The determination of the pavement width and total right-of way shall be based on the operational needs for each street as determined by a technical analysis. The technical analysis shall use demand volumes that reflect the maximum number of pedestrians, bicyclists, parked vehicles and motorized vehicle traffic expected when the area using the street is fully development. Technical analysis shall take into consideration, transportation elements of the Comprehensive Plan, TOD design guidelines, neighborhood plans, approved tentative plans as well as existing commercial and residential developments. All street designs shall be coordinated with the design of other new or existing infrastructure. 3. The minimum geometric & structural requirements for all street classifications are defined in Section 300 of the City of Central Pont Standards & Specifications. 4. The City of Central Point standards & Specifications Section 700 should be consulted for the location and design of required street lighting. The City has a contract with Pacific Power and Light under which PP&L supplies and installs all streetlights, including supply of the anchor baits and bolt template(s). The ground rods, required conduit, and other fittings shall meet PP&L design requirements. 5. Where special lighting fixtures are required such as in the Transit Oriented Development areas, the completed lighting shall provide the same amount of illumination at the street level as would the standard lighting fixture, spacing and pole heights specified in the City's Standards & Specifications Section 700, STORM DRAINAGE Section 400 of the City's Standards & Specifications shouid be consulted for complete details regarding storm drain guidelines. CITY OF CENTRAL POINT PUBLIC WORKS DEPARTMENT STAFF REPORT 4/30/2003 8 It shat[ be the responsibility of the Developer's engineer to investigate the drainage area of the project, including the drainage areas of the channels nr storm sewers entering and leaving the project. If a contiguous annexed drainage area of given size exists, the engineer may use information that has formerly been established if it includes criteria for the drainage are at complete development under current zoning and Comprehensive Pian Designations. if the City does not have such information, the engineer shall present satisfactory information to support his storm sewerage design. The engineer shall also be required to provide all hydrology and hydraulic computations to the Public Works Department that are necessary to substantiate the storm sewer design. The storm water sewer system design shall be in conformance with applicable provisions of Oregon DEQ, DSL and ODFW and United Safes COE and consistent with APWA Storm Water Phase II requirements. 2. E.acal drainage areas not included in a" Designated Flood Zone" as a result of a Federal Emergency Management Agency (FEMA) Study, shall have storm drains of sufficient capacity to carry runoff for a typical 10-year storm, unless the main discharge pipe or stream will have greater than 100 cubic foot per second discharge "Q" during a 10-year storm. When the discharge "Q" of storm drains exceeds 100 CFS, but is less than 200 CFS, that storm drain shall be designed to carry the runoff expected fora 50-year storm. When the main storm drain will have a discharge "Q" in excess of 200 CFS during a 50-year storm, that storm drain shall be designed to carry the runoff expected fora 100-year storm. A rainfall intensity duration Curve is supplied in Section 400 of the City's Standards & Specifications far construction. 3. Unless the engineer can otherwise demonstrate through hydraulic design that the existing facilities such as culverts, bridges or pipe, including any planned future development, will carry the computed discharge, the engineer will be required to design and dedicate detention basins or other facilities for the purpose of reducing the discharge until the downstream facilities have been improved or enlarge, or until other solution have been found. 4. The Public Works Department will require both, apre-condition analysis and apost- condition analysis of the project area that considers all planned ar estimated build-out of future facilities in order to substantiate the project design. 5. The Public Works Department requires that any storm sewer system to be dedicated to the City shall be designed as a "closed system" in order to minimize the effect of ground water infiltration, silt and other undesirable substances, Weep holes and grade rings above the street sub-grade level or hydraulic grade fine in non--street installations, are exempted from the watertight requirement. The system shall also be designed to be "self cleaning" to extent passible. The minimum requirements are as follows: A. A minimum cleaning velocity of 2-fps will be maintained throughout ail CITY OF CENTRAL POINT PUBLIC WORKS DEPARTMENT STAFF REPORT' x/30/2003 9 segments ofi pipe between catch basins or manholes regardless of the type of pipe used. In no case shall the pipe gradient be less fhan 0.005-ft per foot (0.5%). B. Cleaning velocity shall also be maintained through catch basins and manholes except at specially designed sediment cleaning structures as discussed in (section 420.10.04) of the City's Standards & Specifications. Street curb gutters shall be designed to maintain cleaning velocities between curb inlets including the earner radii. C. Many areas in the City of Central Point have a high water table that fluctuates greatly with rainfall amounts as weft as surrounding use. The applicant's engineer should consult section 420.10.02 for requirements related to ground water contrni. SANITARY SEWER Section 500 of the City's Standards & Specifications should be consulted far complete details regarding sanitary sewer guidelines, The sanitary sewer system including all sewer mains, lateral piping, manholes and pumping stations are owned and administered by the Bear Creek Valley Sanitary Authority (BCVSA). Generally, all technical aspects of design, construction, approvals, inspections and testing of sanitary sewers shall be conducted by BCVSA. 2. It shall be the responsibility of the engineer to coordinate the design of the sanitary sewer with any existing or proposed water system facilities, storm water systems, and streets including any appurtenances. The engineer andlor applicant shall be responsible to investigate the area of the project and obtain all required approvals and permits from BCVSA, Public Works Department, ~iackson County and the State of Oregan with respect to construction of sanitary sewer systems. The engineer may use information that has formerly been established by the City and is on file, including previous constructions. The sanitary sewer system design shall be in conformance with BCVSA requirements and specifications, including any applicable provisions of the Oregon Plumbing Code, Oregon DEQ and Oregon OHD. 3. Although BCVSA mandates requirements for the sanitary sewer design the City of Central Point Public Works Department Standards & Specifications includes a sanitary sewer Section 500 for requirements that are coincidental to construction of the sanitary sewer facilities within a City of Centro! Point right-of-way or City easement. WATER SYSTEM Section 600 of the City's Standards & Specifications should be consulted for complete CITY OF CENTRAL POINT PUBLIC WORKS DEPARTMENT STAFF REPORT 4/30/2003 1~ details regarding water system guidelines. Designs shall consider the existing water system, master plans, neighborhood plans and approved tentative plans. The applicant, engineer and contractor shall provide the necessary testing, exploration, survey and research to adequately design water system facilities, which will connect to and be a part of, or an extension of the City water system. 2. All requirements of the Oregon State Plumbing Specialty Cade and the Oregon State Health Department, as they pertain to Public Water Systems, shall be strictly adhered to. 3. Water lines shall normally be located 10 feet south or 10 feet west of centerline of streets. The longitudinal placement of water lines and valves within the intended vehicle wheel path shall be avoided. 4. Exceptions to these requirements may be made in order to avoid cutting and replacing pavement, to avoid conflicts with other existing underground facilities and to permit sanitary sewers to be installed on the low sides of streets. As nearly as practical, mains shall be installed in the same relative location on a particular street with the distance from the centerline of the street being varied as little as possible. 5. Water mains shall not be installed in alleys and the installation of mains within easements across privately awned property is to be done only when absolutely necessary such as the avoidance of dead-end conditions. Such easements when required, shall be a minimum ofi 15-feet in width except that the Public Works Department may require additional widths for major trunk lines and multiple utility easement locations. Easements where required, shall be located adjacent to property lines of a single praperty and shall not straddle property lines. Conditions ofi the easement shall include provisions that the property included in the easement shall not be used for any purpose which would interfere with the unrestricted use for water system purposes including the maintenance, repair, construction or re-construction of such. Under no circumstances will the City grant permission for the construction of any building or structure of any type excluding fences within the easement. 6. A copy of standard City of Central Point easement forms is included in Appendix A of these Standards & Specifications. ~. Separation of water mains, including service lines and sanitary sewers shalt be in accordance with current Oregon State Health Division Rules OAR 333-051-0050(10), figure 1, and / or as modified in these Standards except in all cases where running parallel with each other, there shall be a minimum 10-foot separation unless otherwise approved by the Public Works Department. crTY of c~rvrRaL PorrvT PUBLIC WORKS DEPARTMENT STAFF REPORT 4/30/2003 11 8. Excepting sanitary sewers as noted above, the minimum horizontal spacing between wafer mains and storm sewers, gas lines, electrical utilities, shall be five (5} feet horizontally and twelve {12} inches vertically as measured from the outside of the pipe or conduit. Separation between other public utilities such as Gas, TV or Telephone and similar utilities shall be as determined by the individual utility company or franchisee. 9. In all cases where utilities cross in close proximity fa one another, a cement sand slurry shall be required for separation between any city lines and any utility, !n some cases, depending on size and type of facility, concrete bridging piers or supports will be required to span the water facility. The vertical spacing at sewer crossings shall be designed and constructed in accordance with OAR Chapter 333, Division 61 (10). 1 d. The minimum size far distribution lateral water mains in residential areas shall be 8 inches. The minimum size in multiple-dwelling, commercial and industrial areas shall be 12-inches except that in the sole discretion of the Public Works Department, 8-inch lateral lines may be allowed if flaws meet domestic and fire protection needs in the area. Where fire demands or line lasses might demand larger sized pipe, the engineer will be required to submit hydraulic computations to support the use of 8-inch pipe, or to establish the size required, 11. In certain cases, such as cul-de-sacs, where water lines will not be extended, where not more than ten {1 Q) dwelling units are to be served and no fire hydrants are to be served by the line, a 6-inch diameter water line may be approved. 12. Where no fire hydrants are served and no more than five (8) dwelling units are served, a 4-inch diameter water line may be approved where the line length will be less than 2Q0-feet. 13. Each dwelling and commercial building shall be served by a separate water service connection.
