→Incentives and Credits
Initial construction costs for permeable pavements are typically higher than conventional asphalt pavement surfaces, largely due to thicker aggregate base needed for stormwater storage. However, the cost difference is reduced or eliminated when total life-cycle costs, or the total cost to construct and maintain the pavement over its lifespan, are considered. Other savings and benefits may also be realized, including reduced need for storm sewer pipes and other stormwater practices, less developable land consumed for stormwater treatment, and ancillary benefits such as improved aesthetics and reduced urban heat island effect. These systems are especially cost effective in existing urban development where parking lot expansion is needed, but there is not sufficient space for other types of BMPs. They combine parking, stormwater infiltration, retention, and detention into one facility.

<h3>Objective</h3>
The key objective of the Stormwater Credit Program is to recognize property owners who have
implemented stormwater and/or pollution prevention best management practices (“BMPs”) to reduce
impacts to the City’s stormwater infrastructure by controlling the quantity and quality of stormwater
leaving their property.
<h3>Principles</h3>
The Stormwater Credit Program is designed according to the following guiding principles:
* Available to every non-residential and multi-residential property (including those considered “mixed-use”) in Mississauga, unless otherwise exempt from stormwater charges or receiving a subsidy to offset stormwater charges.
* A clear linkage exists between the credit amounts provided and cost savings to the City’s stormwater program resulting from the implementation of BMPs.
* Property owners have the flexibility to pursue practices that suit the needs of and opportunities on their property.
<h3>Eligibility</h3>
All multi-residential and non-residential properties (including mixed-use properties) are eligible for the
credit program, except for any portion thereof which is receiving an exemption or subsidy reduction to
the stormwater charge. Single residential properties are not eligible for the credit program.
<h3>Credit Schedule</h3>
Stormwater credits are available in each of four categories, which align with the overarching objectives
of the City’s stormwater program as shown in the following table.

|style=" text-align: center"| [[Category]] || style=" text-align: center"|[[Evaluation Criteria]] ||colspan="2" style=" text-align: center" | [[Total Credit (50% Maximum)]]
|-
| Peak Flow Reduction || Percent reduction of the 100-year post development flow to pre-development conditions of the site || Up to 40% ||rowspan="4" style="background:; color:black"| To a total of no more than 50%
|-
| Water Quality Treatment || Consistent with Provincial criteria for enhanced treatment || Up to 10%
|-
| Runoff Volume Reduction || Percent capture of first 15 mm of rainfall during a single rainfall event || Up to 15%
|-
| Pollution Prevention || Develop and implement a pollution prevention plan || Up to 5%
|}
A maximum of 50% credit can be achieved by a property owner or operator. The 50% cap reflects the
maximum proportion of the City’s stormwater program in terms of cost that may be beneficially
impacted by on-site BMPs. The balance of the City’s program requires funding regardless of BMPs that
may be in place on private and public lands.
