improper maintenance can lead to high restoration costs to address inefficient bioswales. an accumulation of large sediments, trash, and improper growth of vegetation can all affect the quality and performance of bioswales. it is beneficial at the planning stages to set apart easements to allow for easier maintenance of biowales, whether it be adequate space to locate machinery or safety to those working. different types of filters can be used to catch sediments. grass filter strips or rock inlets can be used to filter sediments and particulates; however, without proper maintenance, runoff could flow away from the bioswales due to blockage. structural inlets have become more common due to the ease of maintenance, use, and its effectiveness. avoiding the use of floating mulch and selecting the best fit low-maintenance plants ensure better efficiency in the bioswales. depending on a community's needs for a bioswale, a four step assessment program can be developed. visual inspection, capacity testing, synthetic runoff, and monitoring are the four steps that can be used to evaluate performance and maintenance of bioswales.
