Staff Notes Town of Queensbury Planning Board Community Development Department Staff Notes October 22, 2013 Revised for June 17, 2014 Application: SP 41-2014 SEQRA Unlisted Applicant: David Kenny Referrals: Warren Co. Planning Location: 1468 State Route 9 Town Engineer Zoning: CI-Commercial Intensive REQUESTED ACTION: Site improvements/building modifications require review by the Planning Board PROJECT DESCRIPTION: Applicant proposes a second modification to an approved site plan - modifications include changing the 3 small building shapes, slight reduction in square footage and parking alterations for some spaces to be located from front to rear. Pursuant to Chapter 179-9-120 of the Zoning Ordinance alteration to site with an approved site shall be subject to Planning Board review and approval. PARCEL HISTORY: SP 58-13: Modification to approved site plan for the construction of 62,967 sq. ft. outlet retail stores where building #1 is already under construction. The modification involves relocation of the remaining buildings, relocation of parking with a majority to the rear and a new access drive configuration. Site improvements / building modifications require Planning Board review and approval, 10-22-13 SP 13-11: Demolition of existing mall [Reebok Outlet] and construction of a new 55,000 sq. ft. shopping center 5-19-11 BP 13-088: Commercial retail MATERIAL REVIEW: Cover Letter, Application, Stormwater Narrative; SP2 Layout approved and proposed. STAFF COMMENTS: The applicant proposes a 2"d modification to an approved site plan where five store linear complex was proposed originally. The first modification proposed including construction of building one as pod 1 at 9,965 sq. ft. only from the linear store complex then proposes Pod 2 attached to Pod 1 at 9,600 sq. ft., then Pod 3 attached to Pod 2 at 10,800 sq. ft.; in addition three separate retail spaces; 1st at 11,558 sq. ft, 2"d at 10,658 sq ft, and 3`d at 10,658 sq. ft.. The 2"d modification still maintains Pod 1 as 9,695 sq ft already under construction; then Pod 2 at 9,600 sq ft, and Pod 4 at 10,800—where all three pods are connected and have not changed. The changes occur with the 1st retail building to be 12,500 sq ft, 2"d building to be 12,500 sq ft, and the 3`d retail building to be 6,300 sq ft (west to east). All of the buildings will be interconnect with permeable paver courtyard area for pedestrian use. The elevations show a canopy over the sidewalks to the buildings. The site requires and proposes to have 307 parking spaces located mostly to the rear of the property with one access drive roadway for entering and exiting the Outlet area. The project is phased with the northerly building being constructed as phase 1; then phase 2 will include construction of all roads and parking lots; and phase 3 will include construction of the southern three buildings and associated site work. The applicant has provided a stormwater narrative explaining the moving three drywells, relocation of two dry wells, and revising the data to account for sidewalk under the canopy as part of the impermeable surface on the site —no changes to grading or other stormwater management proposed for the site. SUMMARY The applicant has completed a site plan application for the proposed construction of 61,395 sq. ft. of building space with an arrangement of Pod 1-3 connected retail spaces and three separate retail space buildings with an interior courtyard. The site work involves creating a predominately rear parking area with a drive access road directing traffic to the rear of the buildings with some parking in the front. The Board may reaffirm the previous environmental assessment as part of the site plan application review. -2- KENNY SHOPPING CENTER PROPOSED 5/14 SITE PLAN MODIFICATION NARRATIVE-STORMWATER MANAGEMENT CHANGES The purpose of this narrative is to address minor changes to the approved storm drainage design as required to accommodate the proposed May 2014 site plan modifications. Those modifications entail making the southern three buildings rectangular, slight reduction to the size of those three buildings and minor modifications to the southern end of the front parking lot. Drainage on the modified site will remain almost entirely as previously approved. Proposed minor changes are: I. Moving three of the drywells serving the roof of the northerly building from the courtyard area to behind the building. 2. Relocating two drywells serving the southerly entrance road from the rear lawn of the adjacent hotel to the edge of the entrance road where they will be located on the property they serve. 3. Revising the stormwater calculations to account for the fact that 10 feet of the courtyard area immediately adjacent to the buildings will be a concrete sidewalk covered by a canopy roof and will not be permeable pavers. Changes #1 & #2 above do not affect the previously approved Stormwater Management calculations or conclusions as they do not change the size of any drainage areas or amount of calculated runoff; nor do they change the size or capacity of any stormwater management structures or facilities. These proposed changes only affect the location of a few stormwater drywells. Change#3 does affect the area of permeable pavers used for managing stormwater in the courtyard areas. Therefore, we have revised the HydroCAD analysis to reflect the fact that there is a 10 foot wide area of impervious sidewalk and canopy in the courtyard area adjacent to the buildings. Runoff from the canopy will run off onto the permeable paver portion of the courtyard, be temporarily stored in the stone storage course under the pavers and gradually filter into the underlying sandy soils. The attached HydroCAD calculation summary shows that the permeable paver design is adequate to handle the additional runoff from the sidewalk canopy area. <16S> Sidewalk Canop I � 7P Permeable Paver Permeable Paver Courtyard Storage & Infiltration Subcat Reach -on.
