On park sites, pollution prevention is often associated withwith each of these source areas accompanies Table 6.3.1.Options and implementation strategies for a few of thesesource areas will give you some ideas for your park site. The scaleof your LID retrofit project will largely determine how you willproceed. You can usually completesmall-scale LID projects with in-house expertise andresources. Large-scale projects will require external supportfrom consultants and contractors. ===Small-scale projects=== Starting with small-scale projects is a good strategy toincrease interest within your community, determine ifsupport is available from stakeholder groups and gain retrofitexperience. Small-scale projects include retrofitting yourproperty with landscape alternatives, rain barrels or usingpollution prevention strategies and practices. Small-scale projects require few resources and asmall project budget because:* They do not require integration into capital works projects* Engineering consultants are not required* Contractors are not required* External approvals are not required* Consultation with the public is limitedDue to the less significant financial commitment, it can beeasier to build the case for support for small-scale projects.A successful small-scale LID retrofit project on your propertyis a good indication that you are ready to take on a moreintensive retrofit project. You now know the resources that Large-scale projectsLarge-scale projects require significantly more effort, budget,and staff than small-scale projects. Large-scale LID retrofitsinclude:* Bioretention* Enhanced grass swales* Bioswales* Perforated pipe systems* Permeable pavement* Soakaways* Infiltration chambers* Rainwater harvesting (excluding rain barrels)* Prefabricated modules* Green roofs Consider a large-scale project if your place of worship isstriving to be a community leader in sustainability. Large-scaleprojects are often highly visible and attract more publicattention. They may also be the only solutionto site-specific challenges, like poor drainage. Before startinga large-scale retrofit project consider the distinctions that setthese retrofits apart from small-scale projects. ===Integration with long-term infrastructure replacement and rehabilitation plans=== Most large-scale LID retrofits must function with existingsite infrastructure, such as storm sewers, catch basins,and pavement systems. The construction of large-scaleLID practices often requires these systems to be removed,exposed, or replaced. The best time for this type of project is when an infrastructure replacement or rehabilitationproject is already planned.Maintenance programs and budgets that take into considerationthe expected life cycle of critical site components, includingparking lot and roofs, are valuable resources for large-scaleprojects. If the replacement of these features is forecasted inyour site budget well in advance, asses if it is advantageousto incorporate LID retrofits into these projects. Remember,sharing construction materials, construction equipment, staffresources, and time will reduce the budget for your retrofit.For example, installing bioretention, infiltration chambers,or permeable pavement in a parking lot will require theexisting pavement to be removed. Budget and resources thathave been set aside for a parking lot replacement could betransferred to the LID retrofit project. ===Involvement of consultants and contractors=== Consultants are required for large-scale retrofit projects,specifically for the final screening of options, pre-design,detailed design, tender and contract documents, constructionsupervision and administration, and assumption andverification. Site contractors are also required for large-scale LID retrofits.Contractors should be pre-qualified based on previousexperience with similar LID projects. External approvalsLarge-scale retrofits may require a variety of approvals at themunicipal, watershed, provincial, and/or federal level.Since LID is still relatively new, you may encounter policiesor bylaws that present barriers to LID retrofit projects.Alternatively, the municipality may have to amend or enforcesome policies and bylaws to facilitate the implementation ofLID projects on your site.
