Following are our observations/comments:
General:
1. The City's project numbers should be added to all site plan application and all supporting documents.
2. Please provide a signed and sealed copy of the boundary and topographic surveys prepared by
Environmental Design Partnership, LLP and C.T. Male Associated, DPC.
3. The applicant appears to propose a chain across the proposed emergency access road. Please provide
indication as to if this chain is to be locked to the supporting post, and if local emergency services will
be provided with the key to this access route if it is to remain locked.
Water/Sewer Engineering Report:
1. The report should include a discussion regarding the system capacity and adequacy of the downstream
collection, conveyance and treatment systems (up to and including the wastewater treatment plant)to
handle the increase in flow resulting from this project. Please revise accordingly and provide an ability
to serve letter from the WWTP operator.
Traffic Evaluation:
2. The traffic evaluation notes a 20- to 30-second increase in delay as a result from the project at the
intersection of Church St and Myrtle St; however,the study does not evaluate geometric improvements
and only notes monitoring future conditions for possible signal timing adjustments. The applicant
should consider evaluating potential geometric improvements to mitigate the increase in delay.
3. The study notes that there's heavy pedestrian activity that exists across Myrtle street, but does not
discuss/analyze how the project will impact these heavily used crossings.The applicant should consider
evaluating the impact of the project on the pedestrian traffic and whether any additional improvements
are warranted, as the project generates a significant level of traffic.
Site Plans:
4. The second and third sheets (Surveys submitted by D.A. Collins and Environmental Design Partnership,
LLP., Respectively) have incomplete title blocks. Please resubmit these two sheets with complete title
blocks in future submissions.
5. The proposed parking lots on sheets L-2.1, L-2.2, and L-2.3 are assumed to be two different parking
facilities as they provide accessible routes to two different buildings (Parking shown on sheets L-2.2 and
L-2.3 are assumed as part of the same parking facility).The minimum required accessible parking spaces
vary based on the intended use of the medical offices. If these offices are to be used for rehabilitation
purposes or physical therapy, a minimum of 20% of all parking spaces shall be accessible per parking
facility per ADA Chapter 2, 208.2.2. If these offices are intended to be used as outpatient facilities and
are identified as part of the hospital, a minimum of 10%of all parking spaces shall be accessible per ADA
Chapter 2, 208.2.1. If neither of the above apply, an additional accessible parking space must be added
to the parking facilities shown on Sheet L-2.1,while 3 additional accessible spaces must be added to the
facilities shown on Sheets L-2.2 and L-2.3 per Section ADA Chapter 2, 208. Please indicate the intended

SWPPP:
39. The soil test locations are provided in the SWPPP on a sheet that appears to be missing some referenced
information and does not show the proposed layout. Please also show the soil test locations on the site
grading plan for clarity and to ensure there is sufficient soils data for the proposed locations of the
stormwater infiltration practices.
40. Subcatchment 18 on the Proposed Conditions Watershed Map is shown being directed to the infiltration
basin via a culvert.This culvert should be included in the model to ensure that all of the runoff directed
to it under all storm events can be conveyed as shown.
41. Please label each of the hydrodynamic separators on the Proposed Conditions watershed map for
clarity.
42. It appears the hydrodynamic separators are proposed to accept and convey up to the 100-year storm
event. Please verify that this is the case, and if so, that the hydrodynamic units have the capacity to
accept the 100 yr storm event flowrates. The detail provided indicates flow capacities of 3.09 cfs and
6.18 cfs. If the units are not meant to pass the 100 year storm events, please provide a bypass.
43. Please provide a detail for the proposed pocket pond, indicating required elements specified by the
NYSDEC Stormwater Management Design Manual (Design Manual). Please include the following
elements:
j. The proposed pocket pond does not appear to have any pond benches, as required by Section

to meet these standards.
k. It does not appear that any landscaping requirements are indicated for the area of the proposed
pocket pond. Provide a landscaping plan for the pocket pond in accordance with requirements
set forth in the Design Manual.
44. The green roof detail should be updated to indicate the following:
I. Provide a landscaping plan for the proposed green roof, in accordance the Design Manual.
m. Provide the type of waterproofing membrane proposed for the green roof system.
n. Planting soils shall consist of 75% mineral and 25%organic material.
o. The porosity of the drainage system should be at least 25%.
p. Verify that the load bearing capacity of the roof structure is sufficient for supporting the soil,
plants, and any people who will be accessing the green roof.
45. The NOI indicates that it is not planned to disturb more than 5 acres at any one time. The total area of
disturbance is indicated to be 7.4 acres. Please provide a phasing plan depicting which areas can be
disturbed at once without exceeding 5 acres.

46. Section 26 of the NOI indicates erosion and sediment control practices that are proposed for the site.
The list does not include any catch basin inlet protection; however, inlet protection is shown on the
plan details. Please update the NOI accordingly.
47. City Code Chapter 242 requires long-term maintenance of the stormwater management practices. The
following notes need to be added to each SWPPP under Post-Construction Operation and
Maintenance of Storm water Control Devices:
a. "All post-construction stormwater management facilities must be inspected annually by a
qualified professional, a report prepared and submitted to the City Engineer documenting the
inspections as well as the maintenance activities that were completed during the prior year."
b. "The City of Saratoga Springs shall approve a formal maintenance and inspection agreement in
accordance with City Code Chapter 242 for stormwater management facilities to ensure the
practices will be properly operated and maintained in accordance with the long-term
operation and maintenance plans. This agreement shall be binding on all subsequent
landowners and recorded in the office of the County Clerk as a deed restriction on the
property."A draft maintenance agreement was provided and shall be reviewed by the City
and City's counsel.
In order to expedite and simplify the review of revised materials we would appreciate if the next submission
be accompanied by a response letter that describes the revised materials and how our comments were/were
not integrated.
If you have any comments, questions or need additional information, please do not hesitate to contact this
office at 518-273-0055.
