The meeting of the Suffolk Planning Commission was held on Tuesday, July 25, 2023, at 2:00 p.m., in the Council Chambers of the Municipal Building, 442 W. Washington Street, Suffolk, Virginia, with the following persons present: MEMBERS: STAFF: Arthur Singleton, Chairman William Hutchings, Jr., City Attorney Mills Staylor, Vice-Chairman Kevin Wyne, Director of Planning and Gerald Goodman Community Development Mary Ellen Baur Meg Pittenger, Asst. Director of Planning Oliver Creekmore Joshua Bateman, Senior Planner Shannon Wolfe, Planner I Grace Braziel, Planner II Catina Myrick, Administrative Analyst The meeting was called to order by Chairman Singleton and Commissioner Goodman opened with a prayer. The roll was called by Mr. Wyne and the Chairman was informed that a quorum was present. ELECTION OF OFFICERS: Arthur Singleton was nominated as Chairman. This nomination and election of Arthur Singleton as Chairman of the Suffolk Planning Commission was passed by a voice vote of 5 to 0. 1 Mills Staylor was nominated for Vice-Chairman. This nomination and election of Mills Staylor as Vice-Chairman of the Suffolk Planning Commission was passed by a voice vote of 5 to 0. Chairman Singleton appointed Vice-Chairman Staylor, Commissioner Edwards, Commissioner Hicks and Commissioner Eberwine to serve on the Committee on Ordinances, with Mills Staylor serving as Chairman. APPROVAL OF MINUTES: The minutes of the previous meeting were approved as written. PUBLIC HEARINGS: EXCEPTION REQUEST, CEX2023-002, 4351 Abercorn Drive: submitted by Molly Bertsch, Map Environmental Inc., applicant, on behalf of BCQ Towns, LLC, property owner, in accordance with Section 31-415 of the Unified Development Ordinance, to grant an Exception to the development criteria and buffer area requirements of the Chesapeake Bay Preservation Area to permit the installation of decks to encroach into the 100-foot Resource Protection Area buffer, on property located at 4351 Abercorn Drive, Zoning Map 12*32, Parcel 3. The affected area is further identified as being located in the Sleepy Hole Voting Borough, zoned RU, Residential Urban zoning district. The 2035 Comprehensive Plan designates this area as part of the Inner-Ring Suburban Use District. The first item of business was introduced by the Chairman followed by a staff report by Grace Braziel, Planner II. Ms. Braziel stated that this exception request is to allow for 510 square feet of land disturbance within the 50-foot landward portion of the 100- foot Resource Protection Area buffer to construct 12’ x 10’ raised wood decks behind 7 2 townhouses within the Bennett’s Creek Quarter development. The applicant would like to include decks at the rear of each townhouse, which would result in 7 of the decks encroaching within the buffer as some of the townhouses are located along the edge of the RPA buffer. The townhouses where the decks will encroach within the buffer are located within Phase 1 and 2 of the development. The exhibit and buffer restoration depicts three (3) impact areas where the decks will encroach within the buffer and 3 areas for restoration. In total, the applicant proposed to clear of 510 square feet of vegetation within the buffer in order to construct the decks. A total of 2.3 square feet of impervious area is proposed within the buffer that is associated with the twenty-one (21) 4-inch-square posts that are required for the footing of the decks. Impact Area 1 has the greatest impact to the buffer and includes a portion of 4 decks to be constructed in the buffer resulting in 405 square feet of buffer area to be cleared of vegetation. Impact area 2 has 1 deck encroaching within the buffer with 68 square feet of buffer to be cleared and impact area 3 has a portion of two decks to encroach within the buffer with 37 square feet of buffer to be cleared. To offset the impacts to the buffer, 2 units of mitigation is required. The applicant proposed more than the required minimum by providing 3 units of mitigation. Majority of the vegetation is proposed to be planted close to the buffer line as the RPA area is forested. Staff believes the request is self-imposed as the development was not originally designed to incorporate 3 the raised timber decks at the time of site plan, which would have allowed for the overall development and decks to be constructed fully outside of the 100-foot RPA buffer. In reference to the water quality, the decks as proposed are not expected to endanger water quality as they will be constructed over pervious material in an attempt to not increase the impervious area and additional mitigation is being provided than what is required. Staff found that this exception request does not satisfy the criteria as outlined in the UDO as the request is believed to be self-imposed and is not the minimum necessary to afford relief. Therefore, staff recommended denial of this application. Staff provided recommended conditions outlined in the staff report and resolution should the request be considered with a motion for approval. The public hearing was opened and speaking in favor of this application was John Napolitano. Speaking in opposition was Thomas Rein, 119 Suffolk Meadows Blvd., Suffolk, VA. Also, speaking in opposition was Selena Thornton, 1921 Piedmont Road, Suffolk, VA. Speaking in rebuttal was John Napolitano. There being no more speakers, the public hearing was closed. Commissioner Goodman made a motion to approve this application with the amended resolution along with the conditions, seconded by Commissioner Baur and passed by a recorded vote of 5 to 0. 4 ORDINANCE TEXT AMENDMENT OTA2023-006, Electronic Message Boards for Institutional Uses, initiated by the City of Suffolk, for amendments to the Code of the City of Suffolk, Chapter 31, Unified Development Ordinance (UDO), Article 7, Supplemental Use Regulations, Section 31-714, Sign Regulations. The purpose of the text amendment is to update and refine the Code of the City of Suffolk, Chapter 31, Unified Development Ordinance. The next item of business was introduced by the Chairman followed by a staff report by Kevin Wyne, Director. Mr. Wyne stated that this ordinance text amendment is to update the Sign Regulations section of the UDO as it relates to electronic message boards. In the current requirements, electronic message boards are permitted only in the B-2 district and they have supplemental standards, which includes size limitations, may only change every 60 seconds, no flashing or pulsing, messages must be static and the brightness limitations. The proposed text amendment would allow for these signs to be located in any zoning district for institutional uses, which includes churches, schools, hospitals, residential care facilities, other public or quasi-public uses. In that regard, staff recommended approval of this ordinance text amendment. The public hearing was opened. There being no speakers in favor or in opposition, the public hearing was closed. Commissioner Staylor made a motion to approve this ordinance text amendment with the amended Exhibit B, seconded by Commissioner Creekmore and passed by a recorded vote of 5 to 0. 5 NEW BUSINESS: STAFF UPDATE – SOLAR ENERGY FACILITIES Joshua Bateman, Senior Planner, gave a thorough presentation on the Solar Energy Facilities Regulations. STATUS REPORT: Mr. Wyne reported on the results of the June 21st City Council meeting. OTHER BUSINESS: Commissioner Staylor made a motion to direct Planning staff to draft language that would create supplemental use standards for industrial development in the M-1 and M- 2 zoning districts when adjacent to residential districts, institutional uses, or public recreations uses, seconded by Commissioner Creekmore and passed by a voice vote of 5 to 0.

The waiver will not be detrimental to the public health, safety, and general welfare of the community; 5.

Personal, self- inflicted or financial burden shall not be considered as grounds for the issuance of a waiver; 6. The need for a waiver is unique in that it is not so general or recurring in nature as to make reasonably practicable the formulation of general regulations to be adopted as an amendment to the ordinance; and 7.
