Whereas provincial and municipal stormwater management guidelines were developed and implemented prior to the introduction of Bill 44 and Bill 47, the subsequent rapid increase in density will be accompanied by a dramatic rise in impermeable surfaces on a wide array of landscapes throughout the province; And whereas urban stream health is directly impacted by stormwater runoff that is both increased in volume and reduced in quality by impermeable surfaces associated with development; And whereas public education, outreach and environmental protection legislation, bylaws and regulations have not been successful in protecting our streams and environment, current resources available to municipalities to support stormwater management under the implementation of these bills will prove inadequate to ensure protection of these fragile resources: Therefore be it resolved that UBCM ask that the Province amend current legislation to include enhanced stormwater management through zoning bylaws and development permit requirements to slow, sink and spread stormwater.
Ministry of Housing and Municipal Affairs Bills 44 and 47 ensure that proactive zoning for growth will occur within urban containment boundaries and close to frequent transit, and mostly as infill and not greenfield development. This shift will enable more homes in existing neighbourhoods and make better use of infrastructure, amenities, roads, and services. Focusing increased housing supply within existing urban areas is critical to making the most efficient use of land and preserving the intact natural ecosystems that surround our communities. Accordingly, Provincial guidance for small-scale multi-unit housing includes recommendations for lot coverage that are intended to help maintain onsite permeability to reduce impacts to stormwater management and water resources. Additionally, recommended reductions or elimination of parking requirements in Bills 44 and 47 can also significantly increase permeable open space to support more tree retentionplanting and reduce impacts on stormwater flows and infrastructure. Local governments continue to have existing legislated authorities to manage growth in and near hazardous and environmentally sensitive areas, such as development permits. Minimum density requirements do not override development permit areas for environmentally sensitive areas and provincial regulations related to riparian areas and setbacks from watercourses. In addition, to existing legislated authorities, Bill 16 Housing Statutes Amendment Act, 2024 expanded the authority of local governments to secure works and services, road dedications and Transportation Demand Management TDM measures in the absence of a rezoning application. These requirements can collectively support the ability to add more permeable surfaces e.g. street trees, rain gardens, bioswales, plantings and reduce the need for paved areas for cars.
