→Retrofitting
Urban areas are constantly changing, and activities such as sewer upgrades and building renovations create opportunities to retrofit LID BMPs. Coordinating climate adaptation measures with these activities can help lower overall project implementation costs (Voskamp et al., 2015)<ref>Voskamp, I. M., and F. H M Van de Ven. 2015. Planning Support System for Climate Adaptation: Composing Effective Sets of Blue-Green Measures to Reduce Urban Vulnerability to Extreme Weather Events. Building and Environment 83. Elsevier Ltd:159–67. https://doi.org/10.1016/j.buildenv.2014.07.018 </ref>.

*Jarden et al., 2015 demonstrated that catchment-scale retrofits, such as a combination of street-connected [[bioretention]] cells (with and without [[underdrains]]), [[rain gardens]], and [[rain barrels]], can significantly reduce peak flows<ref>Jarden, Kimberly M., Anne J.

*A [[rainwater harvesting|cistern]]/irrigation system and [[Infiltration chambers|soakaway ponds]]/infiltration trench retrofitted into an industrial-commercial lot in Toronto reduced runoff volume from their roof drainage areas by 64% (~650 m2 roof area) and 89% (~204 m2 roof area), respectively (STEP, 2019)<ref name = CALSTONE></ref>.
