HomeMy WebLinkAboutSite Plan (188) STEELTECH SITE PLAN 1. Application for a site plan of development for 31,675 sq ft building and outdoor storage area on property located on the easterly side of Nutmeg Road North and southerly of Strong Road, I zone. 2. Lot size is 11.56 ac. Proposed building coverage is 6%;50% allowed. Proposed impervious coverage is 41%; 65010 allowed. Parking requirement based on the breakdown of uses is 67 spaces. The applicant has provided 52 spaces and is requesting a waiver of 15 spaces. 3. To the rear of the building the applicant is proposing a large storage area for materials manufactured on site. The applicant is not proposing to fence in this area. At this time the area is screened due to vegetation on properties on either side of the site. We have advised the applicant on the zoning regulation requirement requiring outdoor storage to be screened from all public ways. We would request that if this application is approved that an approval condition be added stating that if, in the future, either site to the north or south of this property is developed exposing the outdoor storage on this site, that screening of the storage is required at that time. 4. There are regulated wetlands on a large portion of the site. The IWA/CC held a public hearing on June 21 and approved the regulated activity. They are recommending a bond in the amount of $5,000 and they are no other unusual approval conditions. There is a conservation easement which was required with the original subdivision of this property which was never recorded. The applicant has indicated that it will be put in place with any approval of this property. 5. There is public water and sewer available in Nutmeg Road North. WPCA approval is not required. The applicant should be aware that a $2,000 per developed acre connection charge will be required. 6. The Architecture and Design Review Committe has reviewed this proposal and have the following recommendations: a tall arborvitae planting be placed in the island in between the overhead doors; and at the time a sign is proposed for this building that it be brought back to design review for their input. 7. The landscaping proposed for this development includes a landscaped berm in the front of the building between the parking area and Nutmeg Road North. Also, landscaping is proposed along both the east and west property lines to enhance the appearance of the building. The other landscaping proposed includes riparian vegetation along the relocated intermittent watercourse to help reestablish the wetlands values of this area. 8. The police department has reviewed this proposal and have no comments. If this application is approved, there are no other planning department modifications requested.

The object of the hydrologic study is to determine the effect the proposed site development would have on the present condition peak rates of runoff. The site's storm drainage system will collect and route the stormwater runoff to a proposed detention basin system to be located on the site. The axiom of design used in the hydrologic study was the TR-55 Tubular Discharge method. Determination of peak rates of stormwater runoff adhere to the methods suggested in the Connecticut Soil Erosion and Sediment Control Guidelines. Haestad Methods Quick TR-55 and Pond 2 Hydrologic Program was used to size the detention basin. The pre-development peak rate of runoff from the sit is 3 C.F.S., 7 C.F.S., 9 C.F.S., 14 C.F.S., 16 C.F.S., and 22 C.F.S. for storms with a return frequency of 2, 5, 10, 25, 50, and 100 years, respectively. The post-development peak rate of runoff, without the proposed detention system, to the storm drainage system in South Road is 12 C.F.S., 18 C.F.S., 20 C.F.S., 26 C.F.S., 31 C.F.S., and 35 C.F.S. for storms with a return frequency of 2, 5, 10, 25, 50, and 100 years, respectively. The post-development peak rate of runoff, with the proposed detention system, to the storm drainage system in South Road is 2.9 C.F.S., 3.4 C.F.S., 3.5 C.F.S., 11 C.F.S., 16 C.F.S., 20.7 C.F.S.

Iazzetta, Town Engineer DATE: May 10, 1995 RE: STEELTECH SITE PLAN - #95-16P We have reviewed the drawings dated 4-17-95 and the drainage calculations for the proposed Steeltech Site Plan and have the following comments : Drainage Calculations 1 . Drainage area maps for pre and post development conditions are required. 2 . Drainage calculation for proposed runoff for area #1 - the total area is 1 . 89 acres, however, the calculation for the runoff coefficient indicates the area is 1 . 0 acres . 3 . No calculation showing how the coefficient for area #2 was derived. 4. The detention basin analysis a. What is the water elevation of the 100 year storm? b. Hydrographs not shown. c. Input information not shown. Sheet S-2 1 . The detention basin outlet pipe from the outlet structure to the new manhole is shown as 8" PVC. This pipe is not large enough to carry the predicted 100 year storm outflow. 2 . Width of entrance driveway and radius of approach should be shown. 3 . Energy dissipator should be labeled as such. 4 . Test pit should be dug in detention basin to determine groundwater elevation and soil information. S . Construction entrance pad should be shown. 6 . Catch basin E & S protection during construction should be shown. Marcia A. Banach Re: Steeltech Page 2 . 7 . Relocated Brook a. Details required. b. Grading proposed should be shown. c. Water handling not addressed. d. Stabilization of new channel not addressed. 8 . Silt fence should be placed on both sides of relocated stream. 9 . Scale of drawing should be shown. 10 . A-2 Certification required. 11 . Cleanouts required in sanitary lateral with maximum spacing of 100 ' . 12 . It appears that the sanitary lateral connection is a drop inlet. Only outside drops are allowed. A detail must be shown for the drop. 13. Length and type of pipe for sanitary lateral should be shown. Sheet S-3 1 . Contours should be shown 2. Same as comments #9 and #10 for sheet S-2. Sheet S-4 1 . Detail required for sanitary sewer trench, sanitary drop inlet, and catch basin E & S measures. 2 . Seeding mixture should be shown for detention basin and relocated stream. JCl/jsv STEELTECH SITE PLAN PLANNING COMMENTS Zoning Table 1. Parking calculations should be based on 24,175 sf of manufacturing (no warehouse reference)- also, spaces not proposed to be constructed are not deferred, rather a waiver should be requested from the Commission Togo/Plot Plan 1. Existing treeline should be shown on the plans 2. Note regarding presence/absence of 100 year floodplain should be added 3. Outdoor storage must be screened - please refer to Section 6.1.5.2 Storage of Materials in the Industrial regulations 4.

Frank Borawski, design engineer with the firm PDS Engineering, Inc. was present along with Bill Kohane, owner of the property and proposed building. They explained the proposal to build an industrial building and to have a storage yard for the finished products in the rear of the site. The following is a list of items the committee asked the developer to address and return to the Committee on June 15, 1995: 1. additional landscaping to be located on the southerly side of the building to help provide screening for the rear of the building 2. break up the front wall, in the area of the overhead doors, with some additional landscaping (i.e. island) 3. extend the berm in the front of the property; add deciduous, low lying plantings and shrubs 4. sample of lighting to be used on the site 5. proposed signage for the site 6. recommend breaking up the north side of the building with an architectural treatment or landscaping treatment The meeting adjourned at 7:15 pm. The applicant will be returning to Architecture and Design Review Committee on Thursday, June 15 at 5:30 pm. Respectfully submi Michele R. Lipe, AICP Assistant Planner/Analyst 0 l �S' Sri 4P Wetland flag numbers need to be shown on the plans. A soil scientist report has not been submitted. Finished contours for the stream area need to be shown on the plans. E&S measures are still lacking on the southern stockpile , in the stream channel, and at the detention basin. Narrative on the stream relocation still is not included. This should show detailed steps involved in the construction. Test pit data still has not been included. Hydrology reports show a significant increase in the velocity of stormwater flow off of section 3. This water is not directed to the detention basin. How will this increase be handled. Seeding types and rates for the watercourse, lawn, and the regraded slope on the northern property boundary still need to be shown. Details, and a species list concerning the reestablishment of the riparian zone along the watercourse still hasn't been shown. How does the applicant propose to keep sediment from being tracked off of the dirt storage area shown on the back of the site. The relatively high water table that will be present in this area will be a constant problem with access by heavy equipment. What plans are there to mitigate the loss of proposed wetlands due to filling? Have alternatives to the proposed plan been considered? Please be prepared to illustrate possible alternatives to filling of the wetlands and the relocation of the watercourse to the Commission.
