Common Mistakes And Misconceptions
|Permeable hardscapes are always better than retention ponds for water management.
|Both permeable hardscapes and retention ponds have their own advantages and disadvantages, and the choice between them depends on various factors such as site conditions, budget, maintenance requirements, etc. It is important to evaluate each option carefully before making a decision.
|Permeable hardscapes do not require any maintenance.
|While it is true that permeable hardscapes require less maintenance compared to traditional impervious surfaces like concrete or asphalt, they still need periodic cleaning and upkeep to ensure proper functioning of the drainage system. Neglecting maintenance can lead to clogging of pores and reduced infiltration rates over time.
|Retention ponds are unsightly eyesores that decrease property values.
|Retention ponds can be designed in an aesthetically pleasing manner with landscaping features such as native plants, berms, rocks, etc., which not only enhance their visual appeal but also provide additional benefits such as habitat creation for wildlife and erosion control. Moreover, retention ponds help prevent flooding by storing excess stormwater runoff during heavy rainfall events which can actually increase property values by reducing flood risk in the area.
|Permeable hardscapes cannot handle large volumes of water effectively.
|While it is true that some types of permeable pavements may have limitations in terms of handling high flows or prolonged periods of saturation due to soil type or design considerations; there are other options available such as pervious concrete or porous asphalt which can handle higher volumes more efficiently when properly installed according to manufacturer specifications.
|Retention ponds attract mosquitoes and other pests.
|Properly designed retention ponds should include measures such as mosquito larvae-eating fish species (e.g., Gambusia affinis) or mosquito dunks (larvicide tablets) to prevent mosquito breeding. Additionally, regular maintenance such as removing debris and vegetation from the pond can help reduce pest populations.
