Planning Committee May 9, 2017

Evolution of Suburban Development Older Suburbs Newer Suburbs (Pre-Amalgamation) (Recent years) Provincial Growth Generally weak provincial Strong provincial direction direction, with reliance on towards compact, well connected, Management Direction municipal policies and local pedestrian and transit-oriented business culture communities $ $$$ Land Cost 20-25 units per hectare 34-40+ units per hectare Density Yield (Net-to-Gross Ratio) 61% net 50% net (39% public lands) (50% public lands) Arterial grid, curved collector and Modified and offset grid Street Network local streets, cul-de-sacs for better connectivity Predominantly singles, some Increased share of townhouses Dwelling Types semi-detached and townhouse and introduction of back-to-back townhouses, stacked townhouses, and low-rise apartments $ $$$ Infrastructure Costs Street trees Generally medium size Generally small size 2

Suburban Challenges 3

Building Better and Smarter Suburbs  Building Better and Smarter Suburbs (BBSS) initiated in late 2013 to resolve these suburban challenges while improving land efficiency and liveability  BBSS Strategic Directions and Action Plan report approved at Planning Committee in March 2015 4

Infrastructure Standards Review  Re-examination of infrastructure standards to find efficiencies and reduce lifecycle costs for City and taxpayers  Address concerns from Development Industry  Agreement that infrastructure cost savings for Development Industry would offset the amended Transit Development Charge By-law 5

BBSS-ISR Consolidation  BBSS and ISR were identified as Term of Council Strategic Initiatives  BBSS and ISR consolidated in Fall 2015  Multi-Departmental, Industry and stakeholder initiative 6

BBSS Directions in CDPs  Completed: Riverside South, Kanata North - Ongoing: Mer Bleue, Barrhaven South 7

BBSS Schools Working Group with four school boards aiming to:  Co-locate schools and parks to promote shared facilities and improved land efficiency  Minimize land requirements through reduced setbacks and parking requirements and by placing school bus lay-bys in ROW  Promote active transportation and safety 8

BBSS Parks  Revisions to Park and Pathway Development Manual: New park typologies (e.g. woodland parks and urban parkettes) to support BBSS community design directions 9

Tree Planting in Clay Soils  Revising policy to allow for more and larger trees in certain sensitive marine clay soils with more detailed geotechnical information 10

BBSS Traffic Calming 11

16.5m and 18m Cross-Sections  4 party joint utilities trench agreement resolves spatial conflicts, improves construction coordination, and will result in more trees 12

Arterial Cross-Sections  Eliminated medians, cycle track in boulevard, and reduced width of arterials by average 5m 13

Transportation  OC Transpo: included at pre-consultations for development applications  Guidelines for mini-roundabouts: Pilot project successfully completed for mini-roundabouts at minor collector / local residential roads 14

Stormwater Management  Amended sewer design guidelines to eliminate dry ponds and allow for smaller pipe sizes 15

Water Demand Design Standards  Daily design rates reduced from 350 to 280 litres/capita/day - Using same size pipe, on average allows 25% more units - Expected cost savings of 25-30% on major trunk systems 16

Rear Yard Catch Basins  New standard has been reviewed and approved by water/wastewater working group - Eliminate need for catch basin in rear yard - Avoidance of operation and maintenance costs 17

Pump Stations  Reviewed pump station redundancy and overflow standards - Results in average cost savings of $140/unit - Reduced operation and maintenance costs 18

ISR Financial Results  Long-term maintenance and replacement cost savings to City and taxpayers without impacting Level of Service  Cost savings from revised infrastructure standards are estimated at $1,837 per unit 19

Early Implementation Mattamy Abbottsville (Fernbank, Kanata) 22

Looking Forward: BBSS • Review remaining street cross-sections (collector and local streets) • Ongoing discussions with Schools Boards to develop individual MOUs and a Zoning By-law Amendment • Update Urban Design Guidelines for Greenfield Neighbourhoods Timing : Finalized by Q1 2018 23

Looking Forward: ISR • Re-examine location of service laterals to maximize space for trees • Re-evaluate Fire Underwriter Standards, including Level of Service, water pressure, pipe sizes and hydrant spacing • Review policies for possible sump pump use in new subdivisions Timing : Finalized by Q4 2017 24
