Page 1 of 18 GROWTH AND RESOURCE MANAGEMENT DEPARTMENT PLANNING AND DEVELOPMENT SERVICES DIVISION 123 West Indiana Avenue, DeLand, Florida 32720 (386) 736-5959 TO: Planning and Land Development Regulation Commission (PLDRC) DATE: August 17, 2021 SUBJECT: Revised Ordinance 2021-17 Amending Chapter 72, Code of Ordinances for Non-Exempt Excavations I. ORDINANCE SUMMARY Non-exempt excavations are regulated through the Special Exception process established by the Zoning Ordinance. Section 72-293(15)b.1.iv.D requires the top of bank of a non-exempt excavation to be 150 feet from any natural or manmade surface water body, watercourse, or wetland. The St. Johns River Water Management District (SJRWMD), who issues consumptive use (CUP) and environmental resource (ERP) permits, requires a minimum distance of 50 feet from wetlands and waterbodies. The Volusia County Council directed staff to make revisions to the ordinance that will allow an applicant to reduce the setback to wetlands, if s/he can prove through an industry-accepted model, that a reduced setback would not impact adjacent wetlands and waterbodies. The ordinance includes a monitoring requirement and a subsequent ordinance review to evaluate its effectiveness in protecting wetlands and waterbodies. This item was previously heard by the PLDRC on June 17, 2021. At that time, the PLDRC requested some changes to address water quality, monitoring requirements, and the proposed evaluation period for the ordinance. The commission also requested that the proposed ordinance be reviewed by a professional familiar with water quality issues. The PLDRC stressed the importance of obtaining concurrence from the environmental community. This item incorporates the feedback from the PLDRC, environmental professionals, the environmental community, and the development community. II. BACKGROUND/HISTORY Non-exempt excavations typically include sand mines and borrow pits that involve the extraction of sand materials for use as fill for developments or roadway projects. This type of operation is commercial in nature and has the potential to impact adjacent properties and natural resources. Dewatering is often used to remove the water from the pit via pipes and pumps and return it to the ground after the excavation activities. Dewatering is intended to draw down the water table to dry out the sand. The existing ordinance includes the requirement for a hydrologic study to be submitted as part of the special exception process. It must include a detailed description of
Page 2 of 18 subsurface conditions, a groundwater contour map, a map depicting the thickness and depths of the materials to be excavated, a discussion on environmental impacts on existing area wells, and a recommendation of the necessity to install monitoring wells. A special exception for a non-exempt excavation is allowed in the Forestry Resource (FR), Prime Agriculture (A-1), Rural Agriculture (A-2), Rural Mobile Home (MH-3), Light Industrial (I-1), Heavy Industrial (I-2), Industrial Park (I-4), and Osteen Commercial Village (OCR) zoning classifications. Section 72-293(15)b.1.iv.D requires the top of bank of a non-exempt excavation to be 150 feet from any natural or manmade surface water body, watercourse, or wetland. There are no variance options for this required minimum distance. In response to a constituent request, the Volusia County Council directed staff in April 20, 2020 to review the current minimum setback of 150 feet between a non-exempt excavation and wetlands. Mining ordinances for surrounding counties were reviewed, and staff met with the SJRWMD to better understand their CUP and ERP requirements. Staff also spoke with private interests who provided background on their experiences with typical mining operations. The Growth and Resource Management Director presented the research findings to the Council on April 20, 2021 and requested direction on amending the ordinance. At that meeting, the Council directed staff to initiate an amendment to Section 72-293(15)b that would allow a mechanism to reduce the required wetland setback, under certain conditions. A commonly accepted hydrologic model would be required to demonstrate that short and long-term drawdowns from the excavation activity would not impact the surrounding wetlands and/or water bodies. The council also asked for a review of the revised ordinance after five years to establish a checks and balances on whether it is effective in protecting the adjacent wetlands and waterbodies. Ordinance 21-100, as presented to the PLDRC on June 17, is summarized, as follows; When dewatering is required, the setback will be measured from the dewatering area or the top of bank of the excavation, whichever point is closest to the wetlands. An applicant may request a reduction in the setback subject to review and approval of a detailed dewatering plan, prepared by a licensed professional engineer or hydrogeologist. The county reserves the right to charge the applicant for a third party engineering review. The plan shall demonstrate, using a commonly accepted hydrologic model, that there will be no short-term or long-term drawdown of the adjacent wetland or water body, and that includes an assurance that water extracted from the excavation site shall be directed to the wetland or water body, as appropriate. The plan must show that the water being pumped into the wetland or water body has an acceptable quality that will not result in degradation of the receiving wetland or water body. Finally, the plan must include a monitoring program to ensure that there will be no negative impacts to the wetlands or water body. The monitoring plan requires the placement of monitoring wells in strategic locations to ensure that the drawdown does not negatively affect groundwater levels. The ordinance also provides for a reporting mechanism to the county throughout the excavation process. Volusia County reserves the right to charge for third party review of the dewatering plan, the hydrologic study, and other technical documents submitted as part of the special exception application for a non-exempt excavation.
Page 3 of 18 A performance bond for the costs of reparations is required to prevent permanent damage to the wetlands or wetland buffers due to lowering of the groundwater level. Regardless of the hydrologic evaluation, pursuant to the county’s wetland regulations, a minimum buffer of 25 feet would still be required outside of the Natural Resource Management Area (NRMA) and 50 feet within the NRMA. An environmental impact assessment is also required for properties located in the NRMA. Following the PLDRC discussion and public input, county staff was asked to make some revisions and bring the item back to the PLDRC for a second review prior to sending it to the County Council. Members expressed concern that the ordinance did not include a provision for water quality. They wanted a mechanism included that would provide for an evaluation of pre and post groundwater levels and water quality. They expressed concern about public comments that they had received requesting a strengthening of the ordinance. The PLDRC also wanted a third party environmental professional to review the proposed revisions. Finally, the PLDRC stressed the importance of garnering the support of environmental interests before the second PLDRC hearing. To address these concerns, Professional Engineers from the Public Works and Engineering Departments who regularly participate in the review of excavation projects were consulted. The ordinance was also distributed to E Sciences, an Environmental Engineering firm who is active in the Volusia Association for Responsible Development (VCARD). Additionally, it was distributed to the Volusia/Flagler Environmental Coalition and those residents who provided comments during the first PLDRC hearing. No other comments were received by the county prior to the publication of this staff report. The attached ordinance and exhibit incorporate the relevant changes. The word “water quality” was added throughout, and references to state surface water and groundwater quality standards were added. A requirement for pre and post development water quality sampling was added. The review period to evaluate the new ordinance was reduced from five to two years to determine its effectiveness in protecting the water resources. III. STAFF RECOMMENDATIONS Staff recommends that the commission find the Ordinance 2021-17 consistent with the Comprehensive Plan and forward it to the County Council for final action with a recommendation of approval.

Ms. Smith explained to the 11 Commission that staff is here to discuss proposed revisions to the excavations ordinance. 12 At the April 20, 2021 County Council hearing staff was directed to reevaluate the issues 13 related to wetland setbacks. Ms. Smith stated that this ordinance was only related to 14 nonexempt excavations only. The Volusia County setbacks to wetlands is 150 feet; 15 however, the St. Johns Water Management District only requires a 50-foot setback. The 16 question from Council was why do we require 150 feet, and they expressed concerns of 17 wetland issues related to dewatering. Ms. Smith stated that the distance they can dig 18 boils down to quantity with developers. Growth and Resource Management staff talked 19 to surrounding counties, parties in the environmental community, and others 20 organizations for review and recommendations. Staff then analyzed these findings to 21 update the proposed ordinance. Pages 7-11 of the staff report includes a strikethrough 22 and underlined version of the proposed ordinance to identify the changes. The proposed 23 changes are identified on page 8 of the staff report. Staff proposes that the setbacks to 24 wetlands can be reduced if the applicant can demonstrate through a commonly accepted 25 hydrologic model that there will be no short-term or long-term drawdown of adjacent 26 wetlands or impacts to groundwater quality. The analysis must be signed and sealed by 27 a Professional Engineer (PE) or hydro-geologist, and allows for third-party review when 28 the application is received. The applicant will also be required to have a monitoring 29 program to ensure that neighboring wetlands and wells are not impacted. Regardless of 30 the analysis, per our Zoning Ordinance, minimum setbacks to wetlands is 25 feet if 31 outside of the Natural Resource Management Area (NRMA) or 50 feet if within the NRMA 32 overlay. The proposed ordinance also includes a five-year review to assess the 33 ordinance. No additional comments from the Volusia County Association for Responsible 34 Development (VCARD) were submitted. A letter of opposition from the Environmental 35 Council of Volusia and Flagler Counties (ECVF) was submitted. Additional public 36 comments are found on pages 12-17 of the packet. Ms. Smith stated that the 37 Environmental Management Director was available to answer any questions, and 38 concluded that staff recommended that the Commission find the Ordinance 2021-17 39 consistent with the Comprehensive Plan and forward it to the County Council for final 40 action with a recommendation of approval. 41 42 Chair Ronnie Mills asked for clarification that the proposed ordinance is a reduction to 43 wetland setbacks from the current 150 feet to 50 feet. 44 45 Ginger Adair, Environmental Management Director, responded that the proposed 46 changes were if an applicant wanted to reduce the 150 foot setback requirements they 47 would be required to submit the analysis that Ms. Smith previously explained while also 48 meeting the minimum standards of the Zoning Ordinance. There is also protective

These minutes have not been approved by the PLDRC and are therefore UNOFFICIAL AND SUBJECT TO CHANGE OR CORRECTION. 1 language that clarifies under no circumstance would the setback be reduced more than 2 25 feet plus the appropriate wetland buffer. For example, if the area has a 50 foot wetland 3 buffer requirement, then the closest an applicant could excavate to a wetland, if 4 competent analysis was provided, would be 75 feet. 5 6 Chair Ronnie Mills asked if the sloping requirements would still be in place. 7 8 Ms. Adair responded that requirement would still be in place and this ordinance is focusing 9 on the issue of dewatering. She explained that as developers dig in an excavation pit it 10 can have what is termed a “cone of influence” that could draw down the water levels which 11 can cause impacts to surrounding wetlands. In a typical excavation developers attempt 12 to “dewater” the pit by removing the water out of the pit to make it easier to process the 13 sand. There are a number of different dewatering processes that remove the water from 14 the sand. In cases of adjacent wetlands the developers typically recycle that water back 15 into the adjacent wetland. Presumably under this ordinance change the applicant could 16 submit the signed and sealed analysis of their dewatering plan that demonstrates their 17 project would not impact the surrounding wetlands. Once the application and analysis is 18 received it will have a third-party review from a specialist to determine the quality of the 19 analysis and move forward with the special exception process to reduce the setbacks. 20 21 Chair Ronnie Mills asked if the analysis looked at temporary or permanent impacts to the 22 wetlands. 23 24 Ms. Adair responded that the analysis would have to show no short-term or long-term 25 impacts to the wetlands. 26 27 Being that there were no further questions of staff, the floor was open to public 28 participation or commission discussion. 29 30 Public Participation. 31 32 John Baker, 9 Cunningham Lane, DeBary. He stated that he was the current President 33 of ECFV and the group opposed these changes. Mr. Baker addressed Oviedo’s 34 Ordinance 888 (Evidence 1) and the Volusia County Comprehensive Plan chapters 10 35 and 12 (Evidence 2). He stated that the City of Oviedo and Seminole County have much 36 more stringent borrow pit ordinances, and they do not feel the proposed ordinance is 37 supportive of the Volusia County Comprehensive Plan’s Groundwater and Aquifer 38 Recharge and Conservation elements. He continued that the proposal does not address 39 potential ground water quality issues, but merely addresses groundwater levels. It does 40 not address the potential salinity changes that could occur to surrounding wells or 41 wetlands. He concluded that there does not seem to be any supporting third-party, 42 scientific evidence that supports this extensive change. 43 44 Chair Ronnie Mills asked Mr. Baker if he knew why the City of Oviedo and Seminole 45 County had increased their requirements. 46

He stated that some illegal borrow pits in Seminole were discovered and 3 he believed that is why there was an increase to their ordinance. 4 5 Chair Ronnie Mills asked if either of those issues came about because of water quality. 6 7 Mr. Baker responded in the negative. He stated the proposal in front of the board does 8 not mention water quality and that was his concern with these proposed changes. 9 10 Member Jay Young asked if Mr. Baker had talked to the City of New Smyrna Beach about 11 water quality because he used to work for them and knew they had some water quality 12 issues. 13 14 Mr. Baker responded in the negative and stated he had only talked to individuals as south 15 as Port Orange. 16 17 Mark Watts, Cobb Cole Law Firm, 231 North Woodland Boulevard, DeLand. Mr. Watts 18 submitted Evidence 3, which included Volusia County’s Conservation Land Maps. He 19 mentioned that he worked closely with excavation operators to discuss this proposal and 20 asked the Volusia County Council to review this ordinance. He clarified that the original 21 standard of the 150-foot setback was created in the 1980’s, but upon further research 22 they cannot find out why it was determined to be 150 feet. The proposed ordinance 23 changes do not disregard that original standard; however, gives the opportunity to 24 decrease the standard if the applicant can prove that no temporary or permanent impacts 25 to surrounding wetlands will occur. The current standard has 150-foot setback 26 requirements and does not require any rehydration or monitoring. This proposal gives 27 applicants an opportunity to decrease that setback, if enough data is provided to support 28 protection of the wetlands, while also being required to rehydrate the surrounding 29 wetlands and provide monitoring of the project. Mr. Watts referenced the maps in 30 Evidence 3 that compared how most of the mineral extraction areas identified in Volusia 31 County fell within the Environmental Core Overlay zones and near the major wetland 32 systems. He stated that it was extremely important to conserve and protect these areas. 33 These reductions in setbacks would require detailed impact analysis, implementation of 34 effective dewatering processes, provide monitoring, and rehydration requirements, all of 35 which would provide better protection to the overall area. Ultimately it would allow for 36 fewer sites with maximization of extraction while allowing no temporary or permanent 37 impacts to the surrounding wetlands. 38 39 He finished by stating that whatever the Commission decides on the ordinances, it is 40 ultimately superseded by the Comprehensive Plan elements, which is the ultimate trump 41 card. 42 43 He agreed with Mr. Baker’s comments that water quality is important issue. He 44 referenced page 8 of 17 in the staff report that addressed the dewatering area and 45 measurements, and clarified that the current ordinance does not have any dewatering 46 standards. He continued that Subsection I of the report referenced a closed loop cycle 47 on site to recycle the water into the wetlands. A Consumptive Use Permit (CUP) is 48 typically involved in excavations because up to 10 percent of the water can still come out

Small subsections i and ii eludes to Mr. Baker’s comments about 2 an acceptable water quality and monitoring requirement that ensures the recycled water 3 will not degrade the receiving water body or wetland. Mr. Watts stated that if unintended 4 consequences of one of these developments were to happen there would be a bond in 5 place that requires wetland restoration. Mr. Watts made himself available to answer 6 questions and stated excavation operators in the room were available to answer 7 questions as well. 8 9 Member Jay Young stated that he agreed with Mr. Baker that water quality was not 10 addressed much in this proposal and was concerned about the possibility of salt water 11 intrusion on wells and wetlands. He expressed that we needed to address this concern. 12 He agreed that drawdown was important, but we need to add a water quality monitoring 13 requirement. Having a hydrologist would be extremely beneficial. 14 15 Mr. Watts thanked him and stated they were there to get feedback and input. They would 16 be happy to work with staff and the community to come up with a monitoring standard. 17 18 Member Frank Costa asked who Mr. Watts was representing. 19 20 Mr. Watts stated he was representing the Kemcho operation. 21 22 Member Stony Sixma asked if Mr. Baker had anything else to add. 23 24 Mr. Baker commented that no off-site discharge should be allowed. The discharge could 25 go from one cell to another in order to maintain water quality. 26 27 Member Jay Young asked Mr. Baker if he knew of any ordinances in surrounding areas 28 that addressed water quality and salt water intrusion. 29 30 Mr. Baker stated he was unsure, but knows that the Oviedo ordinance mentions 31 drawdown requirements. 32 33 Member Jay Young stated you could still have drawdown but poor water quality. 34 35 Mr. Watts stated there was an excavation operator in the building that could talk about 36 water quality. 37 38 Tim Laus, 27 North Summerton Street, Orlando. He stated he was a consultant for 39 Kemcho Investments. He addressed Mr. Baker’s concern on water quality and 40 recommended taking a water sample at the beginning of the extraction to establish a 41 baseline and reanalyze during each testing to ensure they maintain that baseline. He 42 feels monthly or quarterly would be appropriate, but annually would be too long in 43 between tests. 44 45 Commission Discussion. 46 47 Member Frank Costa asked how the five year timeline was determined on page 5 of 17 48 of the staff report. He suggested the idea of reviewing the ordinance after 2 years versus
Page 17 of 18 Excerpt from the minutes of the PLDRC hearing of June 17, 2021. These minutes have not been approved by the PLDRC and are therefore UNOFFICIAL AND SUBJECT TO CHANGE OR CORRECTION. 1 5 years. He also referenced page 9 of 17 about items A-E which talked about water 2 quality, but stated there was no timeline or monitoring schedule. He asked if that was 3 listed somewhere. 4 5 Ms. Smith responded that the timeline for the ordinance review is still open for discussion. 6 She also clarified the current ordinance defines the monitoring schedule, and it would 7 also be required to be submitted with the special exception application. 8 9 Member Frank Costa clarified that could be changed with each application. 10 11 Ms. Smith stated that page 8 of the staff report goes into more detail about specific 12 requirements. 13 14 Member Jay Young commented that he would like section iii to mention a specific 15 requirement about water quality testing in addition to the drawdown. He recommended 16 monitoring saltwater intrusion and/or water degradation. 17 18 Ms. Smith clarified that staff will take comments into consideration and modify the 19 proposed ordinance. Then staff would make those changes and go to Council or bring it 20 back to PLDRC once changes were made. 21 22 Chair Ronnie Mills confirmed that the ordinance needed to have a water quality standard 23 established in this proposal. They should also establish parameters on diminishing water 24 quality standards. 25 26 Member Richard Feller commented that he would like staff to make modifications and 27 bring it back to PLDRC prior to going to Council. He agreed with Mr. Costa’s suggestion 28 to review the ordinance after two years versus five years. 29 30 Ms. Adair clarified that the Commission is asking to reassess this ordinance in two years 31 instead of five years, and not the issue of water quality testing. 32 33 Member Frank Costa responded in the affirmative. 34 35 Chair Ronnie Mills asked the Commission if they would they like to have staff make 36 revisions and bring it back to PLDRC with modifications before sending to Council, or 37 allow the staff to make changes and take it directly to Council. 38 39 Member Richard Feller MOVED to MODIFY Ordinance 2021-17 to include water 40 quality monitoring in the ordinance and RETURN to the Planning and Land 41 Development Regulation Commission before being forwarded to County Council. 42 43 Member Jay Young SECONDED the motion and recommended a hydrologist be 44 involved in these updates. 45 46 Motion Discussion. 47 48 Member Edith Shelley asked about monitoring sites and off-site discharge requirements.

The proposed ordinance can 5 be changed to include language to require these issues be identified during the 6 application process and on a case-by-case basis since each site varies. She also 7 recommended to use a hydrologist that has a continuing services contract with the 8 County. 9 10 Motion CARRIED unanimously (6:0).
