What is Rainwater Harvesting and How Does it Compare to Permeable Hardscapes?

Step	Action	Novel Insight	Risk Factors
1	Rainwater harvesting involves collecting and storing rainwater for later use.	Rainwater harvesting is a sustainable way to conserve water and reduce reliance on municipal water supplies.	The initial cost of installing a rainwater harvesting system can be high.
2	Rainwater can be collected from rooftops, gutters, and other surfaces and stored in rain barrels or cisterns.	Rain barrels are a simple and affordable way to collect rainwater, while cisterns can hold larger amounts of water for longer periods of time.	Rain barrels can overflow during heavy rainfall, causing flooding and erosion. Cisterns require more space and maintenance than rain barrels.
3	The collected rainwater can be used for non-potable purposes such as watering plants, flushing toilets, and washing clothes.	Using rainwater for non-potable purposes can reduce demand for municipal water supplies and lower water bills.	Using untreated rainwater for potable purposes can pose health risks due to potential contamination.
4	Permeable hardscapes are surfaces that allow water to infiltrate into the ground, reducing runoff and improving stormwater management.	Permeable hardscapes can help reduce the urban heat island effect and improve water quality by filtering pollutants.	Permeable hardscapes require regular maintenance to prevent clogging and maintain their permeability. They may also be more expensive to install than traditional hardscapes.
5	Rainwater harvesting and permeable hardscapes can work together to improve water conservation and stormwater management.	Combining rainwater harvesting with permeable hardscapes can maximize the benefits of both systems and create a more sustainable and resilient landscape.	The effectiveness of rainwater harvesting and permeable hardscapes may vary depending on local climate, soil conditions, and other factors. Proper design and installation are crucial for optimal performance.

Bioretention Cells: A Key Component of Low-Impact Development

Step	Action	Novel Insight	Risk Factors
1	Identify the site	Bioretention cells are a stormwater management technique that can be used in various settings, including residential, commercial, and industrial areas.	The site must have adequate space to accommodate the bioretention cells.
2	Design the bioretention cells	Bioretention cells are designed to capture and treat stormwater runoff by allowing it to infiltrate into the soil. The design should include the appropriate soil media mixtures and native plant species to ensure effective water quality improvement.	The design must consider the site’s soil type, slope, and drainage patterns to ensure proper functioning.
3	Construct the bioretention cells	The construction process involves excavating the site, installing the necessary components such as the underdrain, and filling the cells with the appropriate soil media mixtures and native plant species.	The construction process must be carefully managed to avoid soil compaction and damage to existing vegetation.
4	Maintain the bioretention cells	Regular maintenance is required to ensure the bioretention cells continue to function effectively. This includes removing sediment and debris, pruning vegetation, and monitoring the soil moisture levels.	Neglecting maintenance can lead to clogging of the soil media and reduced infiltration rates, which can compromise the effectiveness of the bioretention cells.
5	Monitor the performance	Monitoring the performance of the bioretention cells is essential to ensure they are functioning as intended. This includes measuring the volume and quality of the stormwater runoff entering and leaving the cells.	Regular monitoring can help identify any issues with the bioretention cells and allow for timely corrective action.

Bioretention cells are a key component of low-impact development and can provide numerous benefits, including runoff reduction, water quality improvement, and erosion control. These cells are designed to capture and treat stormwater runoff by allowing it to infiltrate into the soil, which is achieved through the use of soil media mixtures and native plant species. However, the success of bioretention cells depends on proper design, construction, and maintenance. Neglecting any of these steps can compromise the effectiveness of the cells and lead to clogging of the soil media and reduced infiltration rates. Therefore, it is essential to carefully manage the entire process, including monitoring the performance of the cells to ensure they are functioning as intended.

The Importance of Using Native Plant Species in Sustainable Landscaping

Step	Action	Novel Insight	Risk Factors
1	Understand the benefits of using native plant species in sustainable landscaping	Native plants are adapted to local climate and soil conditions, making them more resilient and requiring less maintenance. They also provide ecosystem services such as carbon sequestration, water conservation, and pest resistance. Additionally, they support biodiversity and provide habitat for wildlife and pollinators.	None
2	Research and select appropriate native plant species for the specific location	It is important to choose plants that are native to the specific region and habitat type to ensure they will thrive and provide the desired benefits. This may require consulting with local experts or using online resources to identify appropriate species.	Choosing the wrong species could result in poor growth or negative impacts on the ecosystem.
3	Incorporate native plants into the landscape design	Native plants can be used in a variety of ways, including as ground cover, in rain gardens, or as part of a larger habitat restoration project. It is important to consider the cultural significance of native plants and their potential to provide environmental education opportunities.	Poor design or installation could result in plant failure or negative impacts on the ecosystem.
4	Manage invasive species	Invasive species can outcompete native plants and disrupt the ecosystem. It is important to monitor and remove invasive species to ensure the success of native plantings.	Invasive species management can be time-consuming and costly.
5	Maintain the landscape using sustainable practices	Sustainable landscaping practices, such as reducing water use and avoiding chemical pesticides, are important for maintaining the health of native plant species and the ecosystem as a whole.	Failing to use sustainable practices could harm the ecosystem and negate the benefits of using native plants.

Resistance to change and conflicting interests among stakeholders may pose challenges to collaboration and engagement.

Common Mistakes And Misconceptions

Mistake/Misconception	Correct Viewpoint
Permeable hardscapes and rain gardens are the same thing.	While both permeable hardscapes and rain gardens help manage stormwater runoff, they are not the same thing. Permeable hardscapes refer to surfaces such as pervious concrete or porous pavers that allow water to infiltrate into the ground below. Rain gardens, on the other hand, are landscaped areas designed to capture and absorb stormwater runoff through a combination of plants, soil, and mulch.
Only one solution is needed for managing stormwater runoff.	A combination of solutions may be necessary depending on site-specific conditions and goals. For example, a property with limited space may benefit from using permeable pavement in high traffic areas while also incorporating a rain garden or bioswale in low-lying areas where water tends to pool.
Permeable hardscapes require more maintenance than traditional impervious surfaces like asphalt or concrete.	While it’s true that some types of permeable pavement may require periodic vacuuming or power washing to maintain their effectiveness over time, this maintenance is typically less intensive than what’s required for traditional impervious surfaces like asphalt or concrete which can crack and deteriorate over time requiring costly repairs/replacement
Rain gardens only work in wet climates.	Rain gardens can be effective in any climate as long as they’re properly designed based on local rainfall patterns and soil conditions. In fact, dry regions with infrequent but heavy rainfall events can benefit greatly from rain gardens by capturing large volumes of water during storms which would otherwise contribute to flash flooding downstream.
Eco-solutions like permeable hardscapes and rain gardens are too expensive for most people/organizations.	While there may be upfront costs associated with installing eco-solutions like permeable pavement or a rain garden, these costs can be offset by long-term savings in reduced maintenance and stormwater management fees. Additionally, there are often grants or other financial incentives available to help cover the cost of installation.
