Concord, NC 28027 704.786.1783 ♦ 704.795.1564 Fax www.wsacc.org Dear Mayor Eudy: This is a notice of capacity for the flow acceptance request received by the Water and Sewer Authority of Cabarrus County (WSACC) from the Town of Mt. Pleasant on August 8, 2019 and August 14, 2019. WSACC has or will have capacity at the Rocky River Regional Wastewater Treatment Plant and appropriate sewer interceptors to transport and treat the domestic wastewater from the proposed project entitled Skyland Drive Townhomes, located off Skyland Drive. The referenced project will serve 16 twnhomes with three bedrooms each, with a projected wastewater flow of 5,760 gallons per day (gpd). WSACC previously provided a notice of capacity for this project based on the August 8, 2019 submittal from the civil engineer for the project. WSACC is providing this letter to acknowledge the correct name of the development (Skyland Drive Townhomes) following an updated submission from the civil engineer for the project (received on August 14, 2019). As such, WSACC understands that the 5,760 gpd originally allocated is the total flow for the project, and that no additional flow is requested with the updated sub-m—ift-Wh The wastawater generated by his projeGt will be renveyed through a proposed and existing system, and then enter WSACC's system at the existing 15-inch Dutch Buffalo Creek Interceptor. WSACC acknowledges it has or will have capacity for wastewater from the proposed development based on information provided by Alley, Williams, Carmen, and King, Inc. (Civil Engineer for the project) using North Carolina Department of Environmental Quality (NCDEQ) wastewater flow guidelines. The WSACC Capital Improvement Program (CIP) has been on pay as you go since Fiscal Year 2005 — 2006, funding Capital Projects entirely from Capital Reserves, and WSACC expects to continue this policy into the future. Projects on the CIP are subject to approval by WSACC's Board of Directors, support from local governing bodies, regulatory approval, and funding availability. The list and schedule of CIP projects are tentative and are revised periodically to reflect changing conditions and needs. If construction of this project does not commence within two (2) years of the date of this notice, the notice is rescinded and a second request and notice will be required before flow capacity is accepted. Please notify WSACC, in writing, when construction of this project is initiated. This sewer capacity allocation may also be cancelled pursuant to the conditions set forth in the WSACC Sewer Allocation and Commitment Policy. Please note that the final commitment to service to provide wastewater treatment services shall occur upon application for a building permit for the project and when system development fees are paid pursuant to N.C.G.S. §162A, Article 8.

Section III. WSACC Certification Statement: I, J. Thomas Hahn, PE, certify to the best of my knowledge that the addition of the volume of wastewater to be permitted in this project has been evaluated along the route from the connection to the WSACC interceptor to the receiving wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity related sanitary sewer overflows or overburden any downstream pump station en route to the receiving treatment plant under normal circumstances, given the implementation of the planned improvements identified in the planning assessment where applicable. This analysis has been performed in accordance with local established policies and procedures using the best available data. This certification applies to those items listed above in Section I and Section II plus all attached planning assessment addendums for which 1 am the responsible party. Signature of this form indicates WSACC's guarantee of capacity for this wastewater flow. Notwithstanding the guarantee of capacity, WSACC does not make a commitment to service this wastewater flow until a building permit is requested through the Cabarrus County Building Inspections Department and WSACC receives payment of the System Development Fee.
