Storm System Valves

A system valve is a facility that is fitted to a pipeline or orifice in which the closure member is either rotated or moved transversely or longitudinally in the waterway so as to control or stop the flow. System valves are used to regulate pressure, isolate, throttle flow, prevent backflow, and relieve pressure. System valve types include gate, plug, ball, cone, and butterfly. These specific types may be classified as isolation valves. Isolation valves are designed to start and stop the flow of water within the distribution network (and isolate portions of the network for maintenance or repair). Isolation valves are the predominant type of system valves installed in a distribution network. They are commonly intended to be either fully open or fully closed. They are not intended to throttle flow by being partially open. A gate valve is an isolation valve (which is modeled here as a system valve) that is used to prevent water flow via a simple gate mechanism. Gate valves may be motorized (and remotely controlled), and they may also have small bypass valves. Gate valves are not installed in locations where they need to be frequently operated due to the time required to open and close them. A butterfly valve is similar to a gate valve but uses a disk that is rotated ninety degrees to control the flow of water. Butterfly valves operate easier under large pressures and volumes of water than standard gate valves, and are thus found on larger pipes. However, because the butterfly valve disk stays in the water path even when the valve is open, the valve creates a higher resistance to flow (i.e., pressure loss) than a gate valve. Additionally, if it becomes necessary to clean a main by using pigs or swabs, the butterfly valve would block the operation. Butterfly valves can be operated quickly, increasing the risk of serious water hammer.
2025 OCP Road Development Bylaw 9525

Schedule B-10: 15Year Road Network reflects planned future road links expected to be required to accommodate the city growth and development within the next 15years. The Map is based on EMME/3 transportation modeling and the Transportation Network Planning Study (AECOM, 2009). Therefore, the actual road network improvements will depend on how closely city growth matches the projections used in the model. The links are classified into: •Provincial Highways (MoTI jurisdiction): intended to connect Prince George to other regions of the province and beyond. •Arterial Roads: intended for the movement of large volumes of people and goods between different areas of the city; •Major and Minor Collector Roads: intended for the movement of people and goods between local roads and the arterial road network, while providing some degree of access to adjacent properties; and•Local Roads: intended primarily to provide access to adjacent properties.
Water Pressurized Main

A pressurized main is a type of main line that is pressurized. Pressurized main is a concrete class. There are numerous types of pressurized mains in the water distribution model; they include air release, blow off, bypass, chemical injection, distribution main, interconnect, pipe bridge, sampling station, and transmission main. Transmission mains are large-diameter pipelines (24" or larger) that carry large quantities of raw water long distances from their source to a water treatment plant, then to the distribution grid system. Transmission mains generally run in a rather straight line from point to point. Lateral lines are not attached to transmission mains. Distribution mains are average-diameter pipes (4"–20") that transport potable water from transmission lines and redistribute it throughout an area. Lateral lines attach directly to distribution mains.
Flood Plain - FCL Thawleg Intersection

Thalweg : The line of maximum depth in a stream. The thalweg is the part that has the maximum velocity and causes cutbanks and channel migration. As part of bylaw 8285 of the City of Prince George to designate land as flood plain and regulate the development of land that is subject to flooding. “flood construction level” means the Designated Flood Level plus the allowance for freeboard and issued to establish the elevation of the underside of a wooden floor system or top of concrete slab for habitable buildings and areas. In the case of a manufactured home, the ground level or top of concrete or asphalt pad, on which it is located shall be equal to or higher than the above described elevation. “Severe Flood Hazard Area” as delineated on Schedule A includes those areas directly connected to the river channel, where the 200-year flood depth is equal to or exceeds 1 metre above the current ground level.
OCP 8383 ALR Exclusion

As part of Schedule B-1: Natural Environment of the Official Community Plan for the City of Prince George the Agricultural Land Reserve Exclusion is part of the Natural Environment area designations. Schedule B-1: Natural Environment provides context for policies and development permit area guidelines, which can both refer directly to areas on this map. This Schedule includes: Agricultural Land Reserve (ALR), Parks, Significant Slopes over 20% grade, Watercourses, Bodies of Water, Groundwater Protection Development Permit Areas, and Riparian Protection Development Permit Areas.
Flood Plain - 1 in 200 yr Severe Flood Hazard Zone

Severe Flood Hazard Zone polygons; area with depth greater than 1.0m for 200-year flood with no freeboard As part of bylaw 8285 of the City of Prince George to designate land as flood plain and regulate the development of land that is subject to flooding. “flood construction level” means the Designated Flood Level plus the allowance for freeboard and issued to establish the elevation of the underside of a wooden floor system or top of concrete slab for habitable buildings and areas. In the case of a manufactured home, the ground level or top of concrete or asphalt pad, on which it is located shall be equal to or higher than the above described elevation. “Severe Flood Hazard Area” as delineated on Schedule A includes those areas directly connected to the river channel, where the 200-year flood depth is equal to or exceeds 1 metre above the current ground level.
OCP 8383 Future Landuse

Schedule B-6: Future Land Use focuses on areas having different land use policies and designates the following areas: •Downtown •Neighbourhood Centres •Neighbourhood Centre Corridors •Neighbourhood Centre Residential •Neighbourhoods •Neighbourhood Corridors •Neighbourhood Residential •Business Districts: •Regional Commercial •Service Commercial •Commercial Recreation •Community Facility •Light Industrial •Medium Industrial •Heavy Industrial •Parks& Open Space •Utilities •Ruraland Rural Resource: •Rural A •Rural B •Rural C •Rural Resource
Downtown Business Improvement Area

Downtown Business Improvement Area Bylaw 8165 Prince George Downtown Business Improvement Association (“Downtown Prince George”) serves all the property owners and all the businesses/tenants in C1 Zone of Prince George. Each and every property owner and business in the downtown is entitled to a membership with our organization. The organization exists through a municipal bylaw. The current 5-Year bylaw expires in 2018. By way of the bylaw, the organization is funded through a special, property-tax levy paid by all downtown property owners. These costs are then passed on to businesses (renters) via rental rates and/or triple net leases.
