The project as prese accordance with the detention basins, the pretreatment is requ should be revised to 2. On Sheet No. 2, the p area of the vrovosed P.C, 727, Latham, New York 12110-0727 299 ctmale@ctmale.com Compliance Officer of Wakita Motel reviewed the stormwater, grading and access components of the he above referenced project The information we reviewed included ication package, Plan Sheets 1- 6 of 6 (dated February 17, 2004), and a Management Narrative. The documents were prepared by the rtnershiv. LLP. Based on our review of these documents, we offer the nted will require a stormwater permit and the design must be in NYS Stormwater Management Design Manual. With regard to the proposed method of treatment is infiltration. Per the design manual red to remove sediments prior to infiltrating. The infiltration basins ndude pretreatment. an does not clearly show existing or proposed drainage patterns in the access drive at Round Pond Road. Inverts are missing on the existing culvert. 3. On Sheet No. 2, the proposed catch basins should be numbered. 4. On Sheet No. 2, the pipes that drain into the storm basins are steeply sloped. The pipe slope should be reduced a+d the design of the rip -rap apron should be added to the stormwater management report. !I 5. The drainage pipes shown on Sheet No. 2 do not correlate with the pipe system shown in the stormwater manaizement narrative. 6. Pipe sizing calculatiotvs should be incorporated into the narrative/report. 7. On Sheet No. 4, the! use of straw bale dikes across a concentrated flow channel is not recommended per th4 NYS Guidelines for Urban Erosion and Sediment Control. This sheet should be revised to 4how alternative means of sediment control. 8. Sheet No. 4 should 4how the location of the temporary sedimentation basins noting that they can not be locateId in areas slated for infiltration. 9. Sheet No. 4 should @how erosion and sediment control measures in the area where the cabins will be removed, i.e. uphill from the existing motel to remain. This sheet should show the proposed grading in this area. 10. Drainage in the area between the new access drive onto Route 9 and the existing motel is ill defined.

On Sheet No. 4 the hatch basin sediment barrier detail is not applicable to paved areas in contrast to what is s Iown on the plan. 12. Regarding the computer simulation runs, the use of "A" soils appears to significantly lower the weighted curve j! number. It appears that the runoff from the impervious surfaces without the perviouis areas would result in a much larger rate and volume of runoff. Calculations should �e submitted to allow comparison of the results. 13. Regarding the emergency overflow spillway detail on Sheet No. 5, consideration should be given to using turf reinforcing mats versus medium stone filling for aesthetic reasons. 14.
