OMIAL OFFICE Re: Pre - Construction Notification — GC 3890 Authorization Request Providence Retreat Charlotte, North Carolina CSH -14000 Dear Mr. Parker: On behalf of Classica Homes, McAdams is submitting a Preconstruction Notification for approval of 401 Water Quality General Certification 3890 associated with the proposed Providence Retreat development is a single - family residential development, and more specifically, a road crossing aligned across an unnamed tributary to Rocky Branch. The proposed Providence Retreat development is located along Country Lane, approximately 0.33 -miles east of its intersection with Providence Road in Charlotte North Carolina. No additional impacts to waters of the U.S. are proposed. Please find enclosed for your review the following items: - Signed Agent Authorization - Figure 1 - USGS Quad — Weddington - Figure 2 - Mecklenburg County Soil Survey (sheet # 12) - Pre - Construction Notification - Figure 3.1 — Existing Conditions Map (depicting wetland delineation verbally confirmed on January 9, 2014) - Figure 3.2 — Existing Conditions Map with aerial - Figure 4 — Proposed Impact Map (Overall Site Plan) -Inset 1 — Plan View -Inset 1 — Profile View -Inset 1 — Cross Sections - Courtesy Copy of Stormwater Management Plan PROJECT HISTORY & EXISTING CONDITIONS: The subject property lies within the Catawba River basin and within the City of Charlotte. The current Mecklenburg County zoning is R -3 Residential. Land use within the vicinity of the subject property is residential, institutional, and forested areas. The subject property can be characterized as residential, McAdamsco.com Designing Tomorrow's Infrastructure & Communities Mr. William Elliott Pre - Construction Notification - 29 Providence Retreat June 25, 2014 Page 2 of 4 containing one residential structure and one shed. Approximately 70 percent of the subject property is maintained lawn. 'The remaining 30 percent can be generally characterized as a Dry Mesic Oak - Hickory Forest according the NC Natural Heritage, Program classification system. The forested areas are located mostly within the northern and western portions of the subject property. One perennial stream feature, which is an unnamed tributary to Rocky Branch, is observed within the northern section of `the subject property. There is an existing 15 foot wide driveway entrance crossing of the unnamed tributary to Rocky Branch located in the extreme northwestern section of the property. Mr. William Elliott (USACE representative) attended an on -site field concurrence meeting on January 9, 2014 and concurred with the wetland delineation. PROPOSED PROJECT: The proposed Providence Retreat development is a single - family residential development. The proposed development will consist of approximately 16 single - family lots along with associated roadway, utility, and stormwater management improvements. To gain access to the subject property, a proposed road crossing will be aligned across an unnamed tributary to Rocky Branch. As a result, there are proposed stream impacts associated with the road crossing. Additional impacts to the unnamed tributary to Rocky Branch located within the project area not proposed. Impact Table Stormwater Management The proposed development is located within the Catawba River basin with stormwater runoff from the proposed development draining into Rocky Branch. Per City of Charlotte regulations; stormwater management on this site shall meet the stormwater management performance standard's for development set forth in the Charlotte Post Construction Control Ordinance. The proposed project will result' in a significant increase in peak flow rates to downstream properties. To mitigate these impacts, the proposed stormwater CSH- 14000, Proposed Impacts for the Providence Retreat Development Stream Impact (LF): 145 Wetland Impact (Ac): 0 Open Water Impact (Ac): 0 Stormwater Management The proposed development is located within the Catawba River basin with stormwater runoff from the proposed development draining into Rocky Branch. Per City of Charlotte regulations; stormwater management on this site shall meet the stormwater management performance standard's for development set forth in the Charlotte Post Construction Control Ordinance. The proposed project will result' in a significant increase in peak flow rates to downstream properties. To mitigate these impacts, the proposed stormwater CSH- 14000, '"11 MCADAMS Mr. Will'iam'Elliott Pre - Construction Notificatioon - 29 Providence Retreat June 25, 2014 Page 3 of 4 management facility has been sized such that post - development peak flow rates are no greater than pre- development levels in the 10 -, and 25 -year storm events on site. The proposed stormwater wetland is, designed as "TSS -only efficiency" stormwater wetland according 'the Chapter 4.3 of the Charlotte Mecklenburg BMP Design Manual (Revised July 1, 2013). The proposed stormwater Wetland will provide the required 85% TSS removal as well as the 70% total Phosphorus removal required in this watershed. If the development on this tract is built as proposed within this report, then the .requirements set forth, in City of Charlotte regulations will be met without additional stormwater management facilities. However, modifications to the proposed development may require that this analysis be revised. AVOIDANCE & MINIMIZATION: Impacts to the jurisdictional stream located on the subject property have been avoided and minimized to the maximum extent practicable; however, due to infrastructure improvements there are proposed impacts. The existing 15 foot wide driveway access crossing is currently undersized and structurally inadequate to accommodate the proposed infrastructure and residential improvements to the subject property. In addition, the existing driveway access crossing is located within the extreme northwestern corner of the subject property. This current alignment causes sighting issues for oncoming traffic along Country Lane. It would be more conducive, for oncoming traffic, if the entrance to the subject property were aligned more with the adjacent driveway entrance located on the opposite side of Country Lane. Therefore, the proposed crossing alignment into the subject property has been re- aligned to the east almost, directly opposite of the opposing driveway across, from Country Lane. In addition, the proposed crossing alignment has been aligned as close to 90 degrees as possible along the most narrow stream section to accommodate the necessary road width to access the residential community and culverts to accommodate the volume of water within the existing stream. To minimize, the, existing, 15 foot driveway, access wide crossing will be removed and the stream bank_ s will be stabilized' `to allow for natural stream formation to occur. SUMMARY: The proposed Providence Retreat development is a single - family residential development. The proposed development will consist of approximately 16 single- family lots along with associated roadway, utility, and stormwater CSH -14000 McADAMS Mr. William Elliott Pre - Construction Notification - 29 Providence Retreat June 25, 2014 Page 4 of 4 management improvements. Mr. William Elliott (USACE representative) attended an on -site field concurrence meeting on January 9, 2014 and concurred with the wetland delineation. To gain access to the subject property, a proposed road crossing will be aligned across an unnamed tributary to Rocky Branch resulting in 145 linear feet of stream impacts. The proposed project is a single and complete project and confined within the property boundary. Appropriate, land .use control measures will be in place for areas which will require them. Additional impacts to the unnamed tributary to Rocky Branch are not proposed. In addition, compensatory mitigation is not proposed as a result of the proposed impacts. At this time, we are requesting approval that the proposed construction activities associated with the Providence Retreat development are authorized under 401 Water Quality General Certification 3890. Consideration of this project is greatly appreciated. If you should have any questions or require additional information, please do not'hesitate to, contact me at, (919) 287 -0890.

Proposed development on this site will consist of the construction of 16 single - family homes, along with associated roadway, utility, and stormwater management improvements. The proposed development is located within the Catawba River basin with stormwater runoff from the proposed development draining into Rocky Branch. Per City of Charlotte regulations, stormwater management on this site shall meet the stormwater management performance standards for development set forth in the Charlotte Post Construction Control Ordinance. These are as follows: ,Sec. 18 -141 Standards for the Central Catawba District (b)- Standards for high density protects, Any drainage area within a project boundary in the Central Catawba ,district is considered high density when said drainage area has greaten than 24 percent built upon area as determined by the methodology established in the design manual Such high- density projects shall implement stormwater treatment systems that comply'with each of the following standards (1) Stormwater quality treatment volume. Stormwater quality treatment systems shall treat the runoff generated from the first inch of rainfall (2) Stormwater quality treatment All structural stormwater treatment systems used to meet these requirements shall be designed to, have a minimum of 85% average annual removal for total suspended solids Low impact development techniques as described in the design manual can be used to meet this requirement (3) Stormwater treatment system design General engineering design criteria for all projects shall be in accordance with 15A NCAC 2H 1008(c), as explained in the design manual- (4) Stream buffers The S W I M stream buffer requirements apply, in the Central Catawba as described in the city's zoning ordmance, chapter 12. In addition, intermittent and perennial streams_ within the project boundary shall be delineated by a certified professional using U S Army Corps of Engineers and N C' Division of Water Quality methodology and shall be shown in ,the stormwater manageriient permit application along with all buffer areas All perennial and intermittent streams draining less than 50 acres shall have a minimum 30foot vegetated buffer ,including a ten foot zone adjacent to the bank Disturbance of the buffer is allowed, however, any disturbed area must be revegetated and disturbance of the ten foot zone adjacent to the bank shall require stream bank stabilization using bioengineering techniques as specified in the design manual- All perennial and intermittent streams draining greater ,than or equal to 5,0 acres and less than 300 acres shall have a 35 foot buffer with two zones, including stream side and upland Streams draining greater than or equal to 300 acres and less than 640 acres shall have a 50 foot buffer with three zones, including stream side, managed use and upland Streams draining greater than or equal to 640 acres shall have a 100 foot buffer, plus 50 percent of the area of the flood fringe beyond 1,00 feet This buffer shall consist of three zones, including stream side, managed use and upland All buffers shall be measured from the top of the bank on both sides of the stream The uses allowed in the different buffer zones as described in the S. W I M stream buffer requirements in the jurisdiction's zoning ordinance, chapter 12, as well as the other provisions of the S W I M ordinance shall apply in the Central Catawba district (except buffer widths) (5) Stormwater volume control Stormwater treatment systems shall be installed to control the volume, leaving the project site at post- development for the one -year, 24 -hour storm except I- 1 and I -2 zoned developments which are exempt from, this requirement Runoff volume drawdown time shall be �a „mmimufii of 48 hours, but,not7more than 1,20 hours (6) Stormwater peak control For residential land disturbing activities exceeding 24 percent built -upon area, peak control shall be installed for the, appropriate storm frequency (i e, 10 -, 25 -, 50- or 100 year, six -hour) as determined by the, flood analysis provided by the owner or designee using the criteria specified in the design manual or if a downstream, analysis is not performed the peak shall be controlled for °the ten-year and 25 year, six -hour storms For commercial land disturbing activities exceeding 24 percent built -upon area, peak control shall be installed for the ten-year, six -hour storm and additional peak control provided for the appropriate storm frequency (i e, 25 -, 50- or 100 year, six -hour) as determined by the stormwater administrator based on a downstream flood analysis provided by the owner or designee using the criteria specified in the design manual or if a downstream analysis is not performed the peak shall be controlled for the ten-year and 25- year, six -hour storms Controlling the one-year, 24 -hour volume achieves'peak control'for the two -year, six -hour storm For I -1 and I -2 zoned developments, peak control shall' be installed for 'the two-year and ten-year, six -hour storms and additional peak control provided for the appropriate storm frequency (i e, 25 -, 50- or 1,00 year, six -hour) based on a downstream flood analysis or f a downstream analysis is not performed the peak shall be controlled for the two-year, ten-year and 25 -year, six -hour storms The emergency overflow and outlet works for any pond or wetland constructed as a,stormwater BMP shall be capable of safely passing a discharge with a minimum recurrence frequency as specified in the design manual For detention basins, the temporary storage capacity shall be restored within 72 hours Requirements of the Dam Safety Act shall be met when,applicable To meet the above stormwater management standards,, a stormwater wetland is proposed. Please refer to the appropriate section of this report for additional information. Calculation Methodolozy • Rainfall data for this analysis was taken from the City of-Charlotte BMP Design Manual. Please reference the precipitation information section within this report for additional information. Using maps contained - within the Mecklenburg County Soil Survey, the on -site soils were determined to range from hydrologic soil group (HSG) `B' soils to HSG `C' soils. Since the method chosen to compute pre- and post- development peak flow rates and runoff volumes is' dependent upon the soil type, care was taken when selecting the appropriate Soil Conservation Service Curve Number (SCS, CN). A composite SCS CN was computed for each pre- and post - development sub - basin. For example; Subbasin # 1 A in the pre - development analysis consists of approximately 64% HSG `B' soils and 3,6% HSG `C' soils. Therefore, for the open area cover ,condition, the composite SCS CN is computed as follows (assuming good condition): Composite Open SCS CN = (64% x 61)+ (36% x 74) = 66 • A composite SCS Curve Number was calculated for both the pre- and post - development condition for each ,subbasin using ,SCS curve numbers and land cover conditions. Land cover conditions for the pre- development condition were taken from recent survey prepared by The John R. McAdams Company, Inc. and Mecklenburg County GIS. Land cover conditions for the post - development condition were taken from the proposed development plan. • For the ,purposes of computing the pre - development storm events, a 50% open and 50% wooded condition was assumed for the sub - basins yielding less than 50% wooded area in pre - development conditions. • The upstream drainage areas shown in this analysis stop at the property line in order to effectively control runoff from the site without "watering down" the impact from the proposed development. Please note that no offsite drainage is directed to the stormwater facility. • The time of concentration was calculated using SCS TR -55 (Segmental Approach, 1986). The Tc flow path was divided into three segments: overland flow, concentrated flow, and channel flow. The travel time was then computed for each segment, from which the overall time of concentration was determined by taking the sum of each segmental time. • The post - development time of concentration to the proposed stormwater management facility is assumed to be 5 minutes. This provides a, conservative estimate of facility size for design, purposes. • PondPack Version V8i was used in determining the pre- & post - development, peak flow rates for the 10 -, 25 -, and 100 -year storm events, as well as routing calculations for the proposed stormwater management facility. • A stormwater wetland is proposed on this site to treat / manage stormwater runoff from, the proposed development. This facility is based on City of Charlotte design standards. • For 100 -year storm routing calculations, a "worst case condition" was modeled in order to insure the proposed facility would safely pass the 100 -year storm event. The starting water surface elevation in each facility, just prior to the 100 -year storm event, is at the secondary spillway elevation. This scenario could occur as a result of a clogged siphon or a rainfall event that lingers for several days. This could also occur as a result of several rainfall events in a series, before the siphon has an opportunity to draw down the storage pool. Discussion of Results Peak.Runoff Control Requirements `The, proposed project will result in .a significant increase in peak flow rates to downstream ro pperties. To mitigate these impacts, the proposed stormwater management facility has been sized -such that post - development peak flow rates are no greater than pre - development levels in the 10 -, and 25 -year storm events on site. Pollutant and Nutrient Control Requirements The proposed stormwater wetland is designed as "TSS -only efficiency" stormwater wetland according the Chapter 4.3 of the Charlotte - Mecklenburg BMP Design Manual (Revised July 1, 2013). The proposed stormwater wetland will provide the required 85% TSS removal as well as the 70% total Phosphorus removal required in this watershed. 3' Conclusion If the development on this tract is built as proposed within this report, then the requirements set forth in City of Charlotte regulations will be met without additional stormwater management facilities. However, modifications to the proposed development may require that this analysis be revised. Some modifications that would require this analysis to be revised include: 1. The proposed site impervious surface exceeds the amount accounted for in this report. 2. The post - development watershed breaks change significantly from those used to prepare this report. The above modifications may result in the assumptions' within this report becoming invalid. The computations within this report will need to be revisited if any of the above conditions become apparent as development of'the proposed site moves forward. 4
