Eastern Development Corporation40 Plains RoadVtrans Stormwater Design BriefMay 8, 2019

1. Project Description

Eastern Development Corporation (Applicant) proposes the construction of a9,100 SF retail building located at 40 Plains Rd in Pittsford, VT. As existing, the 2.78acre site includes a house, paved drive and concrete slab which will bedemolished and removed. This existing development totals to 9,062 SF (0.21acres) of impervious surface. The proposed project includes a building withroughly a 9,100 SF footprint and a 33-space parking lot, with a total of 34,640 SF(0.80 acres) of impervious surface, or 29% lot coverage (building and parking).The total impervious surface on-site is proposed to increase by 25,578 SF (0.59acres).

As the total impervious coverage on-site is less than 1 acre, there are no staterequirements for stormwater treatment. Per Section 1003.C.2.g of the PittsfordZoning Regulations, stormwater drainage is to be treated on-site where practicaland should not create an adverse impact upon the municipality or neighboringproperties. In accordance with Vtrans standards, proposed peak runoff rates forthe 25-year and 50-year storms should be less than or equal to the peak rates forthe existing conditions where runoff discharges to a state right-of-way. To ensurecompliance with these provisions, the existing and proposed sites have beenhydrologically modeled.

2. Receiving Waters

Stormwater runoff from this site currently leaves the property southeast of thedevelopment through a culvert beneath the neighboring driveway. Thisdischarge location will be referred to as S/N 001. Water then flows through aswale and eventually crosses Route 7 before it discharges to Otter Creek,approximately 3,000 feet south of the project parcel.

3. Existing Conditions

The site currently consists of a 2.78 acre parcel with a single family home locatednear Plains Rd. Impervious cover on the site is approximately 9,062 SF and is

Page 2Stormwater Narrative – Eastern Development CorporationMay 8, 2019

limited to the existing house, driveway and a large concrete slab. The remainderof the site is open space, with grass predominating on the south portion of theparcel and a Class II wet meadow on the east side of the parcel. The wetmeadow contains a seasonal drainage swale which flows to a farm pond. Thefarm pond then drains through a culvert to a swale southeast off the property.The site is relatively flat, with an approximately 1% grade in the north-southdirection and an approximately 2% grade in the east-west direction. In additionto the project area, off-site stormwater flows onto the property. This includes theprominent residential development to the north along Plains Rd. The totaldrainage area to discharge location S/N 001 is approximately 42.8 acres.

On-site soils are predominately Hydrologic Soil Group (HSG) C, with some HSG Asoils in the northwest corner of the property and some HSG D soils in the northeastcorner of the property. A “Natural Resources Map” illustrating these siteconditions is attached to this report.

4. Existing Stormwater System

Currently, there is no engineered or permitted stormwater system on-site.However, drainage for the property leaves the site in two locations. The majorityof the property, including all existing impervious development, flows to theexisting Class II wet meadow and exits the site through a culvert beneath theneighboring driveway at S/N 001. The remainder of the property flows to thesouthwest corner of the property and northwest through a culvert beneath PlainsRoad and eventually across Route 7 to Otter Creek.

5. Proposed Stormwater System

The proposed site, once developed, will drain to the same two locations ascurrently exist. The paved area will be graded and crowned for water to sheetflow from the driveway entrance, loading dock and northernmost two parkingspaces northwest to the existing grassed area. From there, water will sheet flowto the existing drainage swale, wet meadow, and farm pond where it willinfiltrate into the ground or eventually leave the site through S/N 001.

The remaining majority of the parking area will sheet flow to the south where itwill be directed by a constructed swale off the end of the parking lot. The swaledirects flows back to the wet meadow and farm pond where water will eitherinfiltrate or eventually leave the site through S/N 001. Further, there will be a


timber check dam within the swale to detain flows, allowing for infiltration andcontrolled discharge through small orifices in the dam.

The remainder of the site drainage area which currently flows to the existingculvert crossing Plains Road has been greatly minimized. The existing culvertunder Plains Road will be removed and new HDPE drain pipes and yarddrains/catch basins will be installed. This new drain piping will outlet at thewestern side of Plains Road in the same outlet location as the existing culvert.

6. Stormwater Compliance

As proposed development is less than 1-acre of impervious cover there is nostate regulation for stormwater treatment. However, it should be ensured that theproposed project has no undue adverse impacts to the municipality orsurrounding properties.

Vtrans ComplianceAs indicated in Section 5, the proposed site will drain to either the new drain pipeunder Plains Road or S/N 001 at the southeast corner of the side. Runoff from theentirety of the impervious surface on the project parcel (excluding a sidewalk)including the parking lot, drive, and building will be routed to S/N 001 at thesoutheast corner of the site. A small portion of the drainage area along PlainsRoad and Route 7 will be routed through the new drainage piping anddischarge onto the state’s right-of-way. As the drainage area discharging to theright-of-way will decrease after development, the proposed peak dischargerates for the 25-year and 50-year storms will be less than the existing peaks thusmeeting the Vtrans requirements. The existing and proposed drainage areasdischarging to the state’s right-of-way have been hydraulically modelled usingHydroCAD and the peak discharge rates are listed in the table below.

Scenario Plains Road Discharge(cfs) Decrease (%)

Existing Flow Rate (25-year) 1.63Proposed Flow Rate (25-year) 0.86 47.2

Existing Flow Rate (50-year) 1.95Proposed Flow Rate (50-year) 1.02 47.7


7. Conclusions

As outlined in the above table, the proposed development will decrease theamount of runoff discharging onto the State’s right-of-way. Additionally, peakstormwater runoff rates for post-development conditions will be reduced for the25-year and 50-year storms, thus meeting the Vtrans stormwater requirements.
