Project Information and Prior Project History 3d. Explain the purpose of the project: The purpose and need of the proposed Kingston on West Townhome Development is to provide much needed housing for the Historic Wilmore District area of Charlotte, NC. The proposed 34- unit project will replace a 35 unit multi -family apartment complex that was onsite until it was demolished in 2018. The intent for the townhome community is to provide attainable multi - generational housing for residents, as this way of living has become a more prevalent need in the community with the lack of sufficient care facilities for the elderly in the Charlotte Region. The site layout and proposed unit count are largely dictated by our team's sensitive approach; respecting community needs, overcoming limitations with respect to topography, adhering to City of Charlotte's tenuous constraints, and minimization of impacts to waters of the US to the maximum extent possible. 3e. Describe the overall project in detail, including the he type of equipment to be used: The proposed 34-unit townhome project will replace a 35 unit multi -family apartment complex that was previously existing onsite until it was demolished in 2018. In addition to the proposed structures, the project will include associated parking, recreational aesthetics, and stormwater management controls. Typical construction materials and machinery will be used on -site during the construction process. D. Impact Justification and Mitigation la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project: Brief Project History We would like to provide a brief history of our efforts in minimizing the stream and Wetland impacts on the current site. The team met with the USACE for the intent of pursuing an Individual Permit which would allow for 42 townhome units. Based on feedback from that meeting, it was determined that this approach would not be feasible due to the impacts that were proposed. However, it was determined that the option of pursuing a Nationwide Permit would be entertained if we could depict a reduction in impacts and meet the compliance of the NWP regulations. We have since removed 8 units from the proposed site to reduce the impacts to existing streams and wetlands in response and consideration to the feedback. We have reduced the unit count to a point that would allow the project to be economically feasible, 34 units. Any amount of units less than 34 would put additional costs on the residents in terms of Home Owner Association fees and would not be in alignment with our intention of providing affordable/ attainable housing for the multi -generational market. Both of the site plans for the 42 and 34 townhome developments are attached, with the 34 townhome development as the proposed site plan. ECS Capitol Services, PLLC • ECS Florida, LLC • ECS Mid -Atlantic, LLC • ECS Midwest, LLC • ECS Southeast, LLP • ECS Texas, LLP www.ecslimited.com Key Drivers to site layout Charlotte -Water Easement Condemnation — The City of Charlotte has recently placed two 60" CMP culverts within the property line and project limits that significantly impacts where proposed units can be placed on the site. Additionally, the development team is working with the City of Charlotte via the condemnation process as they installed the sewer line via the City's eminent domain authorities. As such, we were and are limited from a site layout perspective as we have to design "around" the newly installed sanitary sewer line and sanitary sewer easement that has been placed on the property by the local water and sewer utility department. See screenshot below. o s.�wti, I �\ w�a".ww:wn Screen raos w.irKn' .n K� i wiim. aio �'som'sn i ,� � ".'rv" :K.o. "�.. • w.-u cexwn HEmv;! Y awnnr,a rowan, mWF�.�•. awr- • .. STS OUt M-� rerv. w. e,ua+ E .� • o�ro..,�..��ora ..Eo.�,rA.s v • P�,w��ew�as — �� n O /e ms� O � a +zesa O we —oc An existing 96" Storm Water pipe crosses site — the proposed project is required to pick up an offsite stormwater system (see ex. 96" CMP in screenshot below), carry the flow through the site, and discharge the water on -site. This burdensome condition severely impacts the layout of the site, the infrastructure costs associated with the requirement, and our project's ability to pursue design alternatives that lessens our proposed stream impacts. As such, our design team introduced the 90 degree turn in the onsite storm water system (shown in blue) as a design alternate to pick up the offsite flow that follows the dashed red line and return it to the appropriate outfall location. Without this design change, the project would be considered infeasible if the on -site storm drain system was placed along the dashed red -line. The proposed stormwater management plan will provide full water quality treatment, channel protection, and will assist in controlling peak control for 10 and 25 year storm events for all on - site impervious surface. The bypass system is only being relocated and will not reduce flows from the existing overall rates and volume. Flooding has been a concern for existing site conditions and behind the current townhomes. The City completed a culvert rehabilitation project that was recently used to address the flooding issues. The proposed stormwater management plan will assist with the current system and discourage future flooding concerns. 5% Commitment to Housing Affordability for fifteen (15) years This project has committed to dedicating up to 5% of its units as affordable housing units that will be deed restricted to ensure housing affordability is maintained for fifteen (15) years as requested and desired by the city of Charlotte. Housing affordability and economic mobility remain a significant challenge in Charlotte NC and Mecklenburg County, as noted in this report, where Charlotte ranked 50 out of 50 with economic upward mobility. As such, this development project seeks to make a positive difference in the lives of those challenged by lack of access to quality housing and economic mobility by providing housing affordability for five percent (5%) of the proposed townhome units. Achieving adequate density and lot yield is paramount to ensuring that the overall project can move forward and include the necessary affordable housing units. Losing additional units (as 6 units have already been lost due to preserving existing wetland areas) would compromise the entire project and certainly reduce and likely eliminate the affordable housing component of the project. Proposed Impacts As part of the proposed site plan, impacts are proposed as follows: Stream A: 270 linear feet of permanent impact for placement of a culvert Stream B: 107 linear feet of permanent impact for placement of buildings Stream C: 90 linear feet of permanent impact for placement of buildings and parking area; 40 linear feet of temporary impact to install outfall for Stormwater SCM. Wetland A:.14 acre of permanent impact for placement of buildings and parking area; .014 acre of temporary impact to install outfall for Stormwater SCM. Request for Waiver and Mitigation ECS performed a site visit on July 28t" to document the condition and aquatic function of the streams and wetlands onsite. All three streams had water flowing in their respective channels. All three streams appeared to receive high amounts of runoff from the adjacent urban setting, and contained high amounts of sedimentation, rip rap, trash, debris, and some type of bacterial growth within the channel. The aforementioned bacterial growth did not appear to be the typical iron oxidizing bacteria found in intermittent and perennial streams, but instead appeared as a dingy dark brown versus a brown or reddish hue typically consistent with iron oxidizing bacteria. No benthic macro - invertebrates were identified within any of the stream reaches. ECS performed the NC Stream Assessment Method on Streams A, B, and C. All three streams resulted in ratings of Low. ECS performed the NC Wetland Assessment Method on Wetland AA, which resulted in a rating of Low. 3 Subsequent to reducing and re -configuring to the greatest extent possible, the total number of townhomes to minimize impacts to waters onsite; and as a result of the streams and wetlands exhibiting low aquatic function, the client requests the use of a waiver to exceed the 300 linear feet of stream impact threshold, and permit proposed impacts under Nationwide Permit 29 (Residential Developments). Client proposes a mitigation ratio of 1.5:1, purchased from the NC Division of Mitigation Services extended service area, which result in a final mitigation ratio of 3:1. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: Disturbance of the stream and wetlands shall be minimized to the extent practicable in order for the proper installation of the facility. The construction techniques shall be conducted in accordance with NCDENR standards. Temporary and additional erosion control measures shall be maintained throughout the construction process. Silt fencing will be placed at the bottom of the slopes to deter sediment and erosion control during roadway development activities. Temporary erosion, sedimentation, and pollution controls will be installed prior to and maintained during the entire construction duration and until final stabilization is established.
