We have reviewed the information submitted in support of this application and offer the following comments: A. PROJECT DESCRIPTION The property in question is a rectangular tract located in the easterly side of Whittlesey Avenue approximately 350 north of the intersection with Ridge Avenue. It is located in the R-T Zone and has an area of 7,500 sf. The property is currently occupied by a 2% story single family dwelling with a 1 story covered porch in front, a detached shed, a garage with an attached shed and a paver driveway. The Applicant is seeking Major Site Plan approval with ‘C’ and ‘D’ variances to construct a 960 sf addition to the existing dwelling. The addition will include 2 apartments with each apartment having 2 bedrooms and a bath. One of the apartments will be on the first floor and the other on the second floor. The Applicant also proposes to remove the existing detached shed and install a drywell in the rear yard to mitigate the increase in runoff from the proposed development. The roof drains from the proposed addition will be connected to the drywell. B. DESIGN COMMENTS 1. Based on our review, we find that the following items from the Township's Site Plan/Subdivision Checklist remain to be addressed: a) As required by NJAC 13:40-7.2, a signed and sealed copy of a survey of the property must be submitted to the Board with the site plan submission. b) Item #20 — Copy and/or delineation of any existing or proposed deed

The architectural plans are unsigned. The Applicant must submit to the Board architectural plans which have been signed and sealed by the Registered Architect preparing same. The Grading Plan must be revised to show the proposed limits of disturbance and the proposed area of disturbance. A pipe bedding detail must be added to the plan. §25-29.2 of the Township Code defines a “Minor Development” as any land development and/or the construction of any site improvements that result in an increase in impervious cover by 400 sf that results in an increase of stormwater runoff but does not meet the definition of a major development. Based on our review, we find that the proposed development is classified as a minor development. §25-29.3.c of the Township Code states that the stormwater management measures for minor development shall be designed to provide erosion control, groundwater recharge and stormwater runoff quantity control through the utilization of green infrastructure techniques as follows: a) Stormwater management facilities shall

o provide erosion control, groundwater recharge and stormwater runoff quantity control through the utilization of green infrastructure techniques as follows: a) Stormwater management facilities shall be designated to manage six inches of rainfall on all new impervious surfaces and meet the standards for runoff quantity and green infrastructure. b) Soil testing shall be performed in accordance with the current rules at N.J.A.C. 7:8. Page 3 of 4

\RTHEO} BUILT ON LEGACY, DRIVEN BY PURPOSE 10. 1 12. 13. 14. c) The minimum standards for erosion control established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules at N.J.A.C.2:9 shall be met. d) Regular and effective maintenance shall be performed for all stormwater management facilities and shall be protected by the owner. §25-29.9.a.1 of the Township Code stipulates for minor developments that for each square foot of increased impervious surface, six inches per square foot of stormwater shall be managed using green infrastructure practices as set out in Table 7. The Applicant proposes the use of a drywell system to mitigate the increase in runoff from the site. It states in Table 7 that the use of a drywell is allowed only where the other listed methods cannot feasibly meet the requirements of this section. Therefore, the Applicant must demonstrate to the satisfaction of the Board that the other listed methods are not feasible for this project. Based on our review of the Drywell Sizing Calculation table on the Grading Plan, we find that the currently proposed system has not been designed to comply with the Township Code. Therefore, the proposed design must be revised to comply with the requirements in §25-29 of the Township Code. . As stipulated in §25-29.9.a.1 of the Township Code, the Applicant must submit all of the required components of the checklist for the site development stormwater plan at §25-29.11.c. The Applicant must demonstrate that all of the required information has been submitted to the Board. There is a discrepancy in the increase in impervious coverage between the Drywell Sizing Calculations and General Note #19. Revise accordingly. It appears that the design vehicle will hit the existing shed when maneuvering out of the proposed parking stalls. Revise accordingly. A separate discharge pipe should be provided for the drywell. The Applicant is hereby advised that any revised plans or other documents submitted to the Board should be accompanied by a cover letter which addresses each of the comments in this review letter and also details any other changes that have been made to the plans as these may not be readily apparent. h:\legacy\howellts1\seo\west orange\zoning board\115.wr20129,v01 - 66 whittlesey ave (perez)\review phase\eme & board prof review reports &
