Class III Landfill Mid-Florida Materials (proposed) Vista Landfill Bay Lake Landfill (private) Orange County Landfill Golden Gem (closed)
Low Recharge Area
Site specific Geologic studies found 70 to 100 feet of clayey confining layer under the site to protect the Floridan Aquifer and Wekiva area
Stormwater Management System
Exceeds Wekiva Pollution Abatement Standards; contains 100 year storm
Impermeable Cap
Over entire 173 acres
Impermeable Liner/ Clayey Soil Barrier Layer Replaces approved unlined C&D landfill Groundwater Monitoring Wells
42 additional wells; tested every 6 months (7 Floridan Aquifer, voluntary)
Waste Coverage
Weekly cover with clayey soils
Post-Closure Care
30 years of care after site closure
Open Space or Park
220 acre open space or park at closure

“Demonstrated no significant
threat to the environment per Rule 62-701.340(b)”
North Site Boundary (Trussel Trail and Golden Gem Road)
Section 32-216(a)(30): A waiver is requested to have a final elevation at closure up to 50 feet above the original elevation of the site, prior to any field activities. The current C&D landfill permit has an approval waiver to 43 feet above grade. Specifically, Class III waste is requested to be landfilled up to a maximum elevation
– Provides Needed additional Class III landfill capacity, in the Public Interest. – Majority of height increase is over 100 acre lined area to fund +$10,000,000 liner cost. – Additional elevation assists impermeable cap runoff to ponds in setback. – 168’ is only 25’ over the 143’ natural high point on the site. – 168’ height is 900’ from Golden Gem Road, gentle 11% (5:1) slope on sides – not visible. – 168’ height blends in with regional hills (150’ to 190’). – Compatible with surrounding properties and land uses.

Wekiva Study Area
Section 32-216(c)(4): A waiver to the restrictions and additional requirements of the Wekiva Study Area, “presumptive prohibition” for Class III landfills in a Primary and Secondary Floridan Aquifer Vulnerability Zones. – Existing C&D landfill is “grandfathered in” and does not have to meet Wekiva Area protections. – Extensive site-specific geological study supports the site is a less vulnerable zone – low recharge. – The proposed Class III liner and cap design is more protective of the environment and the Floridan Aquifer/Wekiva basin than the existing permitted facility. The OCEPD Manager supports the waiver. – Project meets the recommended Best Management Practices of Pollution Abatement for Existing Land Uses in the Wekiva Study Area. – Wekiva vulnerability maps were not intended to be applied to site/project specific decisions under 480 acres, i.e. data not accurate below that level.
Class III landfill water quality protection improvements will be a long-term benefit to Wekiva study area quality

Proposed Districts Village Center Employment Interchange Transition Neighborhood (existing low-density rural) Recreation
Use will be similar in noise, vibration, dust, odor, glare, and heat-producing characteristics that are associated with the current use, adjacent land uses, and the majority of the uses currently permitted in agricultural zoning districts.
The use will meet the performance standards of the agricultural district.
Landscaping will be in accordance with Section 25-4 of the Orange County Code. Waiver approved along adjacent landfill property line. Added opaque buffer along Golden Gem Road.
The use is similar and compatible to the adjacent land uses. The proposed use is a modification of an existing landfill with a special exception.
The use is consistent with the pattern of existing development (rural residential, agricultural, industrial). The proposed modification does not expand the existing 220-acre MFM C&D landfill facility.
The use will not act as a detrimental intrusion to an existing residential area. The use is existing and not expanding. Has been a good neighbor to surrounding rural residential. All surrounding areas are agriculturally zoned, or have special exceptions for industrial type uses.

Seasonal High Water Table Section 32-216(a)(4): A waiver to the five (5) feet minimum separation between the bottom of the lined landfill portion and the seasonal high water table (SHWT).
– Requested to allow steeper slope of liner floor to promote drainage. Current borrow pit floor is too flat. – The alternate 60 mil HDPE liner, with a permeability less than 1 x 10-7 cm/sec, will provide in excess (1,000x) of “equivalent” performance to the impedance of leachate as would have the 5-feet of soil, with an estimated permeability of 1 x 10-4 cm/sec. – Our design concept is to have the liner in the north 100 acres be above the estimated SHWT. – MFM agrees to monitor water levels across the north 100 acres prior to the final liner design.
