V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
This staff report was prepared for the modification request to construct a parking deck over the existing drip field of
The Grove WWTF. WIRO recommends a fence to better secure the field instead of posted signs. There have been
security issues in the past, even though signs are currently posted to restrict access. The parking deck will only
increase public traffic in the area. In addition, perimeter access to field is needed for possible repair equipment.
Clarification of how much space is available for this is requested. MW#1 needs to be replaced due to damage (,see
11/18/2020 inspection report). This well will need to be replaced as soon as possible to continue groundwater
monitoring.
