Following are our observations/comments:
General:
1. The City's project number of 19.299 should be added to all site plan application and construction
documents.
Water Sewer Engineering Report:
2. The report should include a discussion regarding the capacity of the existing City of Saratoga Springs
municipal wastewater system to handle the increase in load resulting from this project, particularly at
SCSD Lift Station No. 1. Please revise.
3. The report does not include any discussion/information for hydrant flow testing. It is recommended
that hydrant flow testing be performed to ensure fire flow/sprinkler and domestic demands can be
accommodated. Please revise the report to discuss this and provide documentation of the results of the
test.
4. A fire flow demand was not provided in the engineering report. Please provide the calculated needed
fire flow for the proposed buildings.
Project Cost Estimate:
5. The provided on-site cost estimate is not reflective of all structures/utilities specified in the design plans.
Missing items on the cost estimate include (but are not limited to): flared end sections, catch basins,
stormwater planters, platform tennis courts with associated fencing,etc. Please revise the cost estimate
to include missing items.
Site Plans:
6. Setback dimensions are missing on Sheets L-1.0, L-2.0, and L-2.2. Please revise the sheets to include
setback dimensions and label setback lines accordingly on all sheets.
7. No value is specified for the "Provided Front Setback Accessory" on the Cover Sheet.
8. The Zoning Board Variance Approval Comment 2 details that "The proposal includes vegetative
screening and a landscape berm to minimize visual impact to the property bordering the proposed
project, a parking lot for Saratoga Hospital". If the parking lot immediately north of the site is the one
referenced, it appears such measures have been omitted from the current plans. Please clarify.

9. A construction entrance is shown on Sheet L-1.0 adjacent to the existing pool.The construction entrance
should be moved to the access point for areas of disturbance; currently, it is located in the middle of an
area of disturbance and does not appear that it would provide any meaningful protection. It may be
beneficial to provide two construction entrances for the two general work areas on the site and because
there are two access points to the site.
10. No pavement/sidewalk, etc. restoration is specified where utilities are proposed to run under existing
asphalt pavement. Please revise the plans to depict and detail all work associated with trenching pipe
through existing pavement.
11. Fire hydrants are not shown in the Site Plans. Please revise the Plans to include the locations and
distances to nearest fire hydrants.
12. Please indicate the size and materials of existing water and sanitary sewer mains that will service the
project. Additionally, Sheet L-4.2 details an "8-foot watermain". Please revise accordingly.
13. Though the handicap accessible parking quota has been met, no van accessible handicap parking spaces
are designated. Please revise accordingly.
14. Please provide additional spot elevations at all handicap parking spaces to assure the slopes do not
exceed the required minimum.
15. Please define the ADA-compliant accessible route from the designated handicap parking stalls to the
existing clubhouse and proposed cabana and ensure it meets all applicable standards and regulations.
16. Please demonstrate compliance with Chapter 9 of the Fire Code which requires fire access roads to
service within 150' feet of all portions of exterior buildings - it appears that there are portions of
buildings on this site that do not meet this requirement. Please provide fire truck maneuvering plan
showing access through the site.
17. A grease trap for the Cabana was specified in the Engineers Report but is not identified on the plans.
Please revise accordingly.
18. The plans do not specify the design, type of construction or materials, or dimensions for the proposed
buildings. Please submit the architectural drawings complete with these specifications.
19. The plans do not include details on any proposed site lighting improvements or modifications. Please
indicate whether additional lighting is proposed or indicate where existing site lighting may be
adequate.
20. The plans show multiple silt fences that run perpendicular to elevation contours. Please revise the
placement of silt fences following NYS Standards and Specifications for Erosion and Sediment Control.
21. Please revise the design to include gas and electric utilities that are to service the proposed structures.
Drawings should reflect the location of utility lines, points of connection and the location of meters.
22. Sheet L-1.0 contains errant hatching that indicates the removal of a concrete patio and walkway beyond
the actual footprint of the concrete indicated in the survey. Please clarify.

23. Detail 1 Sheet L-6.2 does not conform to the City of Saratoga Springs standard details. The specified
pipe zone backfill should be "well graded sand with 3/4-inch maximum particle size and not more than
10%passing#200 sieve...".The plans indicate NYSDOT Size 1&2 crushed aggregate for pipe zone backfill
which has a larger gradation than the City standard. Please revise and cross reference all details to
ensure conformance with City standards.
24. Please add dimensions to the concrete crescent immediately south of the proposed tennis courts on
Sheet L-2.1.
25. Sheet L-2.1 seems to have an errant callout, suggesting to "tie new fence into existing fence" where no
fence exists. Please revise.
26. Sheet L-3.2 shows underdrain and storm lines that run parallel to the proposed Proshop in the
stormwater planter.The stormwater planter detail only shows one pipe underneath the planter. Please
clarify. It appears as if they may conflict (4" UD invert 353.5 and 6" St Invert 352.8) Please also specify
the underdrain material.
SWPPP
27. The Environmental Assessment Form for this project indicates that 1.6 acres will be disturbed while the
Notice of Intent indicates that 2.2 acres will be disturbed. Please correct the discrepancy and show and
list the total area of disturbance on the plans.
28. Section 4.1 of the SWPPP notes: "Seed and mulch bare soil areas within 14 days of disturbance unless
construction will resume in that area within 21 days". However,the SPDES General Permit requires that
stabilization be initialized in such areas by the end of the next business day and be complete within 14
days. Please revise the note accordingly.
29. The NYS Stormwater Management Design Manual (SWMDM) indicates that maintenance activities for
bioretention areas shall include cleaning/reparation of the outlet device when drawdown exceeds 36
hours and limiting vegetation height to 18".These requirements are not included in the SWPPP; please
revise.
30. The stormwater management system for the project includes expansion of an existing wet pond. The
pre-development model assumes the pond storage starting at elevation 349.00 and lists available
volume down to 347.00.
a. Has the pond been surveyed to confirm the existing storage volume?
b. The model indicates an existing 6"outlet at an elevation of 349.00 whereas the survey indicates
a 12" outlet without an invert. Please confirm and revise as necessary.
31. The boundaries of Subcatchments 1 and 4 are not consistent between the pre- and post-development
delineation maps in areas that do not have any proposed grading. Please clarify.
32. The stormwater model indicates that the area west of the bioretention area (Subcatchment 8 on the
post-development delineation map) will discharge to the proposed bioretention area. However, the
Saratoga Golf and Polo-PB#19.299—1st submittal review
April26,2019
Page 5 of 6
grading plan suggests that runoff from this drainage area would be diverted by the retaining wall and
flow south, bypassing the bioretention area. Please confirm and revise as necessary.
33. The HydroCAD model for practice 2P (the stone reservoir for the proposed platform tennis courts) is
not consistent with the site plans/details. The model shows 0.2 feet of storage above the stone which
is not reflected on the plans. Also,the model shows a 96' long by 10' breadth broad-crested weir while
the plans suggest the stone reservoir would overflow towards the low point at the northeast corner of
the reservoir. Please provide details of the platform tennis courts and their relationship to the stone
reservoir being installed beneath them.
34. Please clearly label all practices on the post-development watershed delineation map.
35. FB-2 in the HydroCAD model does not appear to be consistent with any practice shown on the plans.
We assume that this is intended to model a depression in the center of a cul-de-sac on the south side
of the property, but these contours are not labeled in the grading plan and the outlet elevations
included in the HydroCAD model are not consistent with inverts shown on the plans in this vicinity.
Please revise.
36. The yard drain detail in the site plans does not indicate size— please add and confirm consistency with
the HydroCAD model.
37. Please dimension the bioretention weir on the site plans and ensure consistency with the HydroCAD
model.
38. The stormwater planter elevations in the HydroCAD model are not consistent with the elevations noted
on the site plans. The model shows elevations from 359' to 360' with an underdrain at 355', while the
plans show elevations from 356'to 357'with an underdrain at 353.5'. Please revise.
39. The wet pond elevations in the HydroCAD model are not consistent with the elevations noted on the
site plans. The model shows elevations from 345' to 350.5' while the plans show elevations from 345'
to 350'. Please revise.
40. The detail for the wet pond outlet control structure indicates that the outlet pipe is 12" while the
HydroCAD model and site plans show this pipe as 18". Please confirm which is required and revise
accordingly.
41. In accordance with the SWMDM, pretreatment is required for 25%of the WQv for bioretention areas.
Please update the SWPPP to describe how pretreatment is provided and update the plans accordingly.
42. Please clearly indicate which WQv design method described in Chapter 9 of the SWMDM for
redevelopment projects has been applied to the site. It appears that Method II has been selected which
requires treatment of 25%of the total disturbed impervious area and 100%of the new impervious area.
However, WQv treatment has not been provided for some new impervious areas, including the
proposed tennis platforms and proposed warming hut on the north side of the site.
43. The channel protection volume calculations in the SWPPP apply runoff reduction volume from SMP-3
(the wet pond). However,wet ponds do not have RRv capacity in accordance with the SWMDM. Please
indicate how the channel protection volume will be provided for the site.
