Stormwater Management, Erosion and Sediment Policies and Criteria Niagara Region and Niagara Peninsula Conservation Authority – DRAFT T2 Other municipalities have updated their sewer use by-law to cover on-site water quality control treatment technologies for private lands. The City of Burlington, for example, requires that where installed, all grease, oil and stormwater interceptors, and any other type of stormwater quality control device shall be maintained by the owner of the water quality control device and costs for such maintenance shall be the sole responsibility of the owner of the stormwater quality control device. The Town of Halton Hills, through the site plan agreement, specifically states that the landowner must maintain the SWM facility as a condition of the legal contract. The City of Calgary uses ‘Private Maintenance Agreements’ that ensure that the owner maintains private SWM facilities. If the owner does not maintain the facility to provide the minimum level of service, the City will maintain the facility and bill the owner. The Town of Oakville requires that quality and quantity control devices shall be located at the property line for municipal access. If access from the property lines is not possible, easements may be required. The District of Saanich, British Columbia requires maintenance schedules and proof of maintenance provided for all private systems annually. For the first three-years of operation a maintenance bond must be provided to the municipality. After three-years of adequate maintenance, the maintenance bond would be returned to the owner. After the maintenance period, the owner is to continue to monitor and maintain the facility to provide the required level of service. If the owner does not maintain the facility, the municipality shall undertake the works and then bill the owner. Site Plan Control By-laws The site plan control by-law gives the municipality the power and authority to designate the municipality as a site plan control area. This means that site plans for new developments and redevelopments must be approved by Council before building permits can be issued. The by-law also allows the municipality to identify areas that are exempt from site plan control. Development types typically subjected to site plan control include industrial, commercial, institutional, and multiple residential units (i.e., in excess of four units). Through the site plan control by-law the municipality will also specify development types exempt from site plan control such as low density residential, additions less than 30 m 2 , new dwellings in a plan of subdivision, and agricultural areas. Municipalities develop site plan control manuals that identify submission requirements for site plan applications for new development and redevelopment. The manual identifies to the developer the requirements and expectations in order to obtain a building permit. Section 1.27 in Appendix N provides further information and policy direction regarding site plan control specifically relating to SWM and minimizing the potential impacts of development on water resources. Downspout Disconnection By-laws The City of St. Catharine’s has a downspout disconnection program that requires homeowners to disconnect downspouts that outlet into sanitary/combined sewer systems. By disconnecting downspout connections to combined sewer systems homeowners are helping to prevent CSOs. During heavy rainfall events, stormwater contributions to the combined sewer system overloads the sanitary system and can result in raw sewage being released untreated into a receiving water body. The downspouts are disconnected and redirected to pervious surfaces such as lawns or water gardens where the runoff has the opportunity to infiltrate. Downspouts can also be connected to rain barrels and used to store the rainwater for irrigation purposes.

Stormwater Management, Erosion and Sediment Policies and Criteria Niagara Region and Niagara Peninsula Conservation Authority – DRAFT T3 Drainage By-laws Municipalities are preparing drainage by-laws that address runoff water quality and quantity, and the need for sediment and erosion controls. The by-laws, for example, prohibit the draining of swimming pool and hot tub water directly into storm catch basins. The by-law will also prohibit encroachments such as roof leaders extended beyond property lines into buffers. The City of Calgary has a drainage by-law where excavation of a parcel has been authorized by the issuance of a building, excavation or other municipal permit, and water may be directed from the site into a storm drainage system. However, the runoff shall be filtered to prevent silt and debris from entering the storm drainage system. The City of Calgary is committed to providing water quality for stormwater runoff and therefore during development and construction of both large and small parcels of land sediment and erosion control is required. Site Alteration By-laws and Soil Preservation By-laws The Town of Fort Erie Site Alteration By-Law manages the alteration of the grade of land, the filling or draining of wetlands, the filling of valleylands and woodlots, and topsoil preservation. This by-law protects areas where there is currently no means for the regulation of issues such as drainage, predevelopment land disturbances, golf course development, as well as the protection of topsoil, farmland or environmental areas (however, site alterations that are part of normal farm practices are exempt). The Site Alteration By-law provides not only for the reparation of damages to the land, but it allows for the imposition of fines of up to $25,000 for individual offenses and up to $100,000 for corporate offenses. Property Standards The by-law for Niagara on the Lake, City of Thorold, City of Niagara Falls, and City of Port Colborne prescribes the standards for the maintenance and occupancy of property prevents the surface ponding of SWM. By-laws would need to be amended to provide the opportunities to implement at source SWM controls that would require temporary surface ponding. Snow Disposal By-laws Snow disposal by-laws consider snowmelt water quality and locations where snow disposal areas are permitted. Groundwater sensitive areas are not good locations for snow dumps and provisions should be made to control melt water from a quality and quantity perspective. Front Yard Parking By-laws Municipalities, such as the Town of Richmond Hill, are adopting by-laws that restrict the widening of driveways and reduction in landscaped area. By-laws such as this one are effective at preventing an increase in impervious area. Pesticide Reduction By-laws Municipalities should adopt, or up-date existing by-laws to minimize the risk of water quality impacts as a result of pest management to control weeds, insects and diseases. These strategies should include: Use of biodegradable pesticides, (herbicides are counted as pesticides); Reduction in the use of pesticides through: o Aggressive crop growth to compete with weeds; o Use of cover crops as biological weed control; o Crop rotation; o Rotation of pesticides; o Selective area applications and maintenance of accurate records; o Use of tillage to control weeds;
