00 Duplainville Site Plan 20230008: Site Plan Review
Ms. Halliday:
On May 25, 2023 via email, we received a series of comments prepared by Laberge Group
regarding our previous submission. Our responses are below: Site Plan Application and Review Submittal Checklist
1. Stockade screening fence along south property line should match Saratoga Springs standard detail F-01.
If a different type of fence is desired, a detail should be provided.
The detail has been revised to match F-01.
2. Pavement section detail: NYSDOT asphalt mixtures referenced are 404 series, which are warm mix asphalt
(WMA). Applicant should utilize hot mix (HMA) or replace detail with Saratoga Springs Standard.
We have provided the Saratoga Springs standard detail.
3. The applicant should confirm that the City standard specification for concrete (detail SS-07) is being met
or exceeded for this project.
The City’s concrete specifications have been added to sheet C-501. Details 03, 05, & 11 on
this sheet have been revised to reference this specification.
4. The stormwater catch basin detail references the plan for dimensions. However, in many instances the
plan view does not indicate a size and some are shown to be rectangular but are noted with diameters,
implying a round structure. The applicant should clarify inlet sizes and be sure to include any applicable
City standard detail ST-04 minimum dimensions or references when making adjustments.
Plans have been revised to provide sizing of structures and grates/covers.

5. Sheet C-121: Although all stormwater management will rely on infiltration, each infiltration basin should
include an overflow with an armored outlet channel to direct potential overflows to a location that does not
impact infrastructure.
Further comment: Although it is unlikely the overflow from Infiltration Basin (IB) #4 will be utilized, it is
currently directed to the neighboring property to the west. The applicant should assess the offsite impacts
that will result from potential severe storm overflow, or from storm events when the ground is frozen. In
addition, the applicant should confirm that the HDPE pipe shown to be installed beneath the railroad track
will have sufficient strength to resist the potential train weight.
2 V
In the unlikely event that Infiltration Basin #4 exceeds it’s 100-year peak elevation of 325.68’ by more than two feet and discharges over the spillway provided, flows would be directed to
an existing off-site depression. This area is visible in the top-right corner of the grading plan.
This area is located hundreds of feet from any existing structure.
We can confirm that the HDPE pipe shown has sufficient strength to be located under the
future railroad tracks.
Traffic Report
1. Although the report concludes that impacts at Geyser Road will not need further analysis, the impacts on
the level of service of other roads within the industrial park such as Duplainville Road and Cady Hill Blvd.
should be considered.
Further comment: It is understood that the project, on an individual basis, does not meet the threshold
requirement for further analysis of the receiving roads. However, the City should keep track of the
cumulative impacts on those roads caused by this and other nearby, future projects to develop their own
understanding of when the threshold will be met.
Acknowledged.
We trust you will find this material to be in order. Once you have reviewed the material,
