16 1 permeable pavement, you could receive as much as 75 percent of additional impervious 2 surface on the lot based on that amount of pavement. He said staff is studying the need for a 3 cap. 4 Commissioner Jacobs asked if staff has talked to OWASA about this. 5 Michael Harvey said that will be part of the peer review. He said authorization would be 6 needed from the Board prior to the peer review process. 7 Commissioner Jacobs asked if owners will have to maintain the BMP. 8 Michael Harvey said yes, a management agreement will have to be recorded at the 9 register of deeds office, and the owners will have to agree to maintain the system. 10 Commissioner Jacobs asked if more staff will be hired to monitor these BMPs. 11 Michael Harvey said this was one of the cons listed. He said he is not sure if more staff 12 will need to be hired, but there will be an increased level of required enforcement. 13 Commissioner Jacobs said he thinks of BMPs from an agricultural standpoint, and these 14 can be a fairly substantial facility. He asked if these could possibly be a neighborhood hazard if 15 not properly maintained. 16 Michael Harvey said that could be a potential problem. 17 Commissioner Jacobs asked if the state standards are higher or lower than Orange 18 County's standards. 19 Michael Harvey said Orange County is more restrictive than the state. He said Orange 20 County chose to be more restrictive in these areas due to the fact that these are primary water 21 sources. 22 Commissioner Jacobs said basically the Board is authorizing staff to take this to a public 23 hearing. 24 Michael Harvey said yes. 25 Commissioner Jacobs said there have been past discussions about a septic tank 26 monitoring system, and if people are going to be putting in BMPs, perhaps they should be 27 paying a fee for monitoring. He said these enhancements can potentially have an adverse 28 effect on other people's properties and on County resources. He said most people do not give 29 a lot of thought about monitoring their septic systems and the protection of groundwater 30 resources. 31 Michael Harvey said the impervious surface limit is important for the County's 32 participation in the state watershed management program. He said there are separate 33 regulations governing the installation of stormwater devices. He said this is regarding a 34 voluntary program where a property owner would be engaging in the installation of a 35 stormwater feature (BMP) with the benefit of receiving additional impervious surface. He said it 36 is important to understand, moving forward, that there are existing state and county 37 requirements that all BMPs have to be maintained in perpetuity. 38 Commissioner Pelissier agreed with Commissioner Jacobs with regard to asking for 39 OWASA's input on this issue, and she would also like for the Commission for the Environment 40 to review it. 41 Michael Harvey said these entities can be part of the peer review that is being 42 recommended. 43 Commissioner Pelissier suggested staff and the OWASA board should review this. 44 Craig Benedict said reviews can be solicited prior to the Quarterly Public Hearing (QPH) 45 and the comments can be made part of the public comment at the QPH. 46 Commissioner Dorosin said there was discussion about the idea of looking at 47 impervious restrictions in other districts. He asked for clarification on why this is being brought 48 up.
