Nace, P.E. February 2010 Revised: May 2014 File: #47491 1 1 __ STORMWATER MANAGEMENT REPORT FOR MICHAEL RINGER 104 MAIN STREET REDEVELOPEMNT SITE MODIFICATION INTRODUCTION The existing site is comprised of two parcels that will be combined into one parcel. The northern parcel fronts the south side of Main Street and the southern parcel is adjacent and fronts Linda Avenue. The owner received Planning Board Approval in the summer of 2010 to construct a crushed stone parking area on a portion of the Linda Avenue parcel for use by the occupants of the Main Street parcel. The additional parking area and site work was originally proposed due to the Main Street Reconstruction Project and to bring the site more into compliance with the with the Town's Main Street Design Standards. Previously customer parking was located in front of the building and was accessed directly off of Main Street. It was proposed to replace this front parking with parking along the sides and rear of the building. This parking was to be accessed by a one way driveway around the sides and rear of the building. The areas along the sides of the building were previously paved and only needed to be striped for parking. The area in the rear of the building was previously grass and was to be graded and graveled for the driveway and parking. The existing front parking area was to be replaced by a grass area with a walkway and planter. The configuration of the access drive and parking is shown on the attached site sketch. The existing mobile home was to be left in place. Since the approval of the previous site redevelopment, the owner has removed the grass area and mobile home located on the Linda Avenue parcel and graded the entire Linda Avenue parcel as a dirt parking area. The current modification to this property includes additional impervious surface area. We propose to re-grade and install new crushed stone parking in the area of the current dirt parking and install two new drywells to handle the added runoff. The purpose of this report is to show that the proposed new drywells will accommodate the additional drainage. EXISTING CONDITIONS The existing site is very flat. The northern portion of the site, including the front half of the roof, front parking, and half of the side access drives drains generally toward Main Street. The rear half of the roof and access drives drain generally to the south. Soils on the site are very pervious, deep and well drained Oakville sands. Due to the flatness of the site, much of the runoff puddles on site and infiltrates into the soil. 1 rf :\ M_ \ I L RIMIER -, \I \ IN: STIfft.
