Water Servicing

• Limited water infrastructure exists in the

NCP area.

• Water supply is from the Grandview

pump station and reservoir on 24 Ave / 168 St.

• To service the NCP area, new feeder

mains, distribution mains and pressure zone boundaries are required.

• New feeder mains are required along 24

Ave for the 142m and 110m pressure zones.

• 142m Zone is supplied by Grandview Pump

Station and Grandview Reservoir.

• 110m Zone is supplied by the Grandview

Reservoir.

• 90m Zone is supplied by the 110m Zone via

PRVs.

Water Servicing

• No existing sanitary sewer infrastructure in

the NCP area.

• To service the NCP area, a network of gravity

sewers, a pump station, a force main and an interceptor are required.

• Based on topography, the pump station will

also service areas outside the NCP (shown in grey)

Sanitary Sewer Servicing

• The NCP area is currently serviced by open ditches

and culverts, typical of rural and agricultural areas.

• The existing system conveys stormwater to the

Nicomekl River lowlands, to the north.

• A servicing plan has been developed to:

– Protect downstream lands from prolonged flooding – Protect receiving watercourses from erosion – Maintain base flows in creeks – Maintain water quality in creeks, ditches and storm systems – Safely convey runoff to large river systems – Protect the natural environment adjacent to watercourses

Stormwater Management

Stormwater Management

• 5 stormwater catchments
• 4 stormwater catchments require detention ponds
• To mitigate the increase in impervious surface

runoff, infiltration measures are required, such as:

– pervious pavement – absorbent lawns – vegetated buffer strips – road infiltration trenches

• To help maintain water quality, the follow BMPs are

recommended:

― inlet sumps ― oil-water separators ― water quality swales

Draft Cost Estimate

Servicing Type Stage 1 Cost Estimate (2013) Stage 2 Draft Cost Estimate (2016) Change in Cost Stormwater $36,240,000 $36,660,000 $420,000 Sanitary Sewer $22,260,000 $17,330,000

• $4,930,000

Water $13,770,000 $10,580,000

• $3,190,000

Total $72,270,000 $64,570,000

• $7,700,000

Engineering Servicing - Next Steps

 Finalize servicing strategies for water, sanitary sewer and stormwater.  Update cost estimates, based on any changes to the servicing strategies.  Identify any interim scenarios, if development may occur in advance of any infrastructure improvements.  Identify any DCC shortfalls attributed to servicing the NCP area and consider funding mechanisms to address the shortfalls.

TRANSPORTATION STUDY: Traffic Modelling

 Additional traffic modelling initiated in May

• f 2016, for additional consultant services

that will extend beyond the Redwood Heights NCP area;  Traffic model will forecast the fully developed scenario and expand the study area to identify traffic impacts the developed area will have on the City and Provincial road networks;  Results of the additional work will delay the completion of the NCP, but will allow staff to complete the Stage 2 component of the Redwood Heights NCP.

Potential Land Use Changes

Land Use amendments may be required surrounding Highway 15 Corridor depending on Transportation study Outcome and Ministry of Transportation input? Key areas of possible changes may include:

 Area surrounding 24 Ave and Highway 15;  Areas surrounding Highway 15;  Areas near proposed Intersections along Highway 15

• Potential for RGS

Amendment of Urban Containment Boundary

STAGE 2 – Other Outstanding Issues

 Determine cost of “Greenspace Levy” and financing strategy;  Prepare “Design Guidelines” for the various land uses and features such as: greenways, walkways, selected streets, neighbourhood gateways, entrance points, gathering places and buffers;  Establish list of “NCP Amenity Contributions needed to serve area including: park development, fire, police and library needs.  Establish per unit “Application Surcharge Fee” to recover NCP ‘consultant’ preparation cost.  Prepare an “Implementation Strategy” to guide the development in keeping with the NCP's Vision, Principles and land Use Concept Plan.
