Pipe grades between manholes and structures shall be uniform to eliminate low spots and provide unrestricted flow. Piping shall not be laid in water or when trench conditions or weather are unsuitable for such work.
Storm Drainage System. The Storm Drainage System is assumed to include a sump pump system consisting of one pump in each of the four dock areas for a total of four (4) pumps located on the site. The pumped storm water is to be piped to the retention basin nearest each of the dock areas. Sheet drainage will be utilized to convey stormwater wherever possible. Site Sanitary Sewer System consists of an eight inch (8”) sanitary sewer line from the building to the sewer main located in West Lower Buckeye. FIRE — Water service for fire suppression shall consist of two (2) ten inch (10”) taps on an existing water line located in 45 Avenue, joining to form a 12” line just beyond the backflow preventer and connecting to the building near the center entrance along the building’s south wall. An eight inch (8”) fire line will be installed for the building’s exterior fire protection with fifteen (15) on-site fire hydrants located in the parking area around the building perimeter per local codes. DOMESTIC/IRRIGATION — Domestic water service shall consist of a single three inch (3”) water tap located in 40xx Xxxxxx. This line shall be extended into the building for domestic water service. In addition to the domestic water connection in 45th Avenue, two (2) Two inch (2”) taps will be made in the main located in West Lower Buckeye, near the southwest corner of the property. A line will be placed from the south end of the building to a valve box at a point near the taps. Final connection of the line will be made in a future tenant improvement. Irrigation water service shall consist of a one inch (1”) line also tapped off of 40xx Xxxxxx.
Storm Drainage System. 1. A complete storm drainage system serving all roof areas, areaways, terraces, etc. shall be provided. In accordance with DEP regulations, a storm water roof-top detention system will be provided.
2. All areas above grade shall flow by gravity through multiple house drains to sewers in adjacent streets.
3. Sump pump pits and silt traps will be provided to serve all storm drainage located below the elevation of storm water house drains and the foundation drainage system if required. Each sump pump station will have duplex sump pumps and provided with emergency power.
Storm Drainage System. Also referred to in Schedule “H” hereto are drawings and reports approved by the Township and by the Conservation Authority describing the Works which are to be undertaken in order to prevent adverse effects on the environment or existing municipal infrastructure due to storm water runoff for both a minor and a major rainfall event in relation to both water quality and quantity. All interim or permanent measures shall be in accordance with the Environmental Compliance Approval issued by the Ministry of the Environment for storm water work in the Subdivision, the terms and conditions of a permit issued by the Conservation Authority and the requirements established in the Approved Drawings and reports referred to in Schedule “H” and any other stormwater plans and reports required and approved by the Conservation Authority or the Township. In addition, all interim or permanent stormwater management measures shall be in in accordance with current provincial legislation. The storm drainage system referred to in this Section 7.2 shall be of sufficient size, depth and at locations within the limits of the Subdivision or on adjacent road allowances, to service lands outside the Subdivision which will, in the opinion of the Township and the Conservation Authority, require the use of the Subdivision system.
Storm Drainage System. If the DEVELOPMENT does not contain any Storm DrainageSystem components, this Section includes the following language:
A. The DEVELOPMENT does not contain any storm drainage system components.
Storm Drainage System. All storm drainage is hydraulically designed to statutory requirements.
Storm Drainage System. 1. The buildings’ storm drainage system is designed based on 2.5” rainfall hour per 100 year storm. The piping distribution will be a “conventional” consisting of a primary roof drainage and secondary overflow roof drainage system. It will discharge above grade and spill to the Civils’ onsite surface drainage system.
2. Pipe support will be provided at intervals so as to prevent strains and stresses that might result in a failure of the system from expansion, contraction, structural settlement pipe movement and building movement.
3. Storm drain pipes shall be tested in accordance to applicable codes, regulations and ordinances; at minimum test piping under static pressure for one hour. Test piping systems after installation and prior to being put into use, covered or concealed by insulation, backfilling or building construction.
4. The Office area storm drainage system will consist of Interior roof drains and overflow roof drains constructed of PVC. The storm leaders will be routed down thru floor and discharge through face of curb at multiple points. Round to rectangular transitional outlet will be provided as required. The Warehouse area storm drainage system will consist of exterior downspout and overflow scupper system constructed of prefabricated/manufactured sheet metal. Vertical downspout will discharge at multiple points 12” above and onto the surface of the concrete truck aprons. Each pair of six-inch roof drain and six-inch overflow drain or vertical downspouts and over flow scuppers are sized to capture a maximum horizontal projected roof area of 16,000 square feet.
Storm Drainage System. The POM storm drain system consists of approximately 15,000 linear feet (LF) of paved drainage ditches and approximately 69,000 LF of storm drains. The system also includes approximately 70 culverts, 150 catch basins, 85 drainage manholes, and five (5) underground storm water retention fields. The OMC and former Fort Ord storm drainage system consists of approximately 17,520 LF of paved drainage ditches and approximately 179,630 LF of storm drains. The system also includes approximately 47 culverts, 461 curb inlet basins, 103 out fall basins, 655 inlet basins, and 310 manholes. These components are shown on site maps and drawings located in the CADD/GIS Room in Building 4455. The POM and OMC currently discharge storm water runoff to the Pacific Ocean and Monterey Bay through five (5) storm drains and two (2) natural stream channels. A small portion of storm water is collected by diversion to cisterns located on the POM. The storm drainage system at the POM is divided into six (6) zones as indicated in the storm water system drawings.
Storm Drainage System. All stormwater runoff, drainage, retention and treatment improvements within the Property shall be designed in accordance with the Zoning Ordinance and Chapter 16 of the Code of Ordinances. All stormwater runoff and drainage system structural improvements, including culverts and piped infrastructure, will be constructed by the Developer and dedicated to the Town. The Town shall not accept such drainage system structural improvements for public ownership and maintenance until certificates of occupancy have been issued for at least eighty percent (80%) of all buildable lots in any subdivided portion of the Property pursuant to the applicable approved subdivided plat of such portion of the Property. Upon final inspection and acceptance by the Town, the Developer shall provide a one-year warranty period for all drainage system structural improvements within the Project. Retention ponds, ditches and other stormwater retention and treatment areas will be constructed and maintained by the Developer and/or an Owners Association, as appropriate.
