Dear Mr. Veitch:
Barton & Loguidice, D.P.C. (B&L) has completed a review of the following reports and
information for the Skidmore College, Fitness and Tennis Center project located at 815 North
Broadway proposed by Skidmore College:
• Application for Site Plan Review with Application Checklists;
• Complete Streets Checklist;
• Full Environmental Assessment Form (FEAF), dated 11-20-2019 and signed by Daniel
Rodecker, as prepared by Skidmore College;
• Cost Estimate for Letter of Credit;
• Engineering Report for Water and Sanitary Sewer dated November 26, 2019 as prepared
by The LA Group, P.C.;
• Stormwater Pollution Prevention Plan (SWPPP) dated November 25, 2019 as prepared
by The LA Group, P.C.;
• Plan Set (7 Sheets) dated November 26, 2019 as prepared by The LA Group, P.C.
This review was conducted on behalf of the City of Saratoga Springs. The above referenced
documents and information were reviewed only with respect to our scope outlined in our task
order/proposal.

General
1. The project site is predominantly a disturbed area of tennis courts/turf areas and some
undisturbed, wooded site area with a drainage course buffered with mature trees.
2. Existing utilities are close by and able to be connected to. Confirm conditions at existing
manhole, bench and steps, see comments below regarding sanitary and storm sewer
connections.
3. Add NYSDEC stormwater permit to question B in Part I of FEAF. Isn't a line extension
necessary to serve the new building? Re-consider entry on FEAF D.2.c.iii.
4. How would a fire truck turn-around in front of the new Fitness Center? Increase radius
of pavement curves at new tee intersection near new hydrant if necessary. Please
clarify.
5. Some unit costs in the cost estimate seem quite low. Examples are concrete sidewalk at
$5 per square foot and particularly for heated concrete at $7.50 per square foot. Please
clarify and revise.
6. Are any special precautions necessary to take place between construction activity and
existing Greenburg Child-Care Center? Are there protective fences, dust control and
sound attenuation practices proposed or work scheduled for non-operating times?
7. Can some of the mature trees around the existing and newly expanded detention basin
be saved? These provide good shade structure and buffering to the drainage course as
well as filtering sheet runoff.
Water and Sanitary Sewer
1. Where will a RPZ backflow preventer be located for this project, inside the building?
Factor in RPZ and all head losses for fire prevention calculations to verify sprinkler
receive adequate pressure.
2. Route new 6-inch water main around periphery of proposed bio-retention basin.
3. Open existing sanitary sewer manhole and assess need to move internal steps if in close
proximity to new pipe from the Swing Building.
Stormwater
Storm water Pollution Prevention Plan (SWPPP)
1. Include manufacturer's printed maintenance manual for proprietary hydrodynamic
separator as appendix and reference in section 6.0. Indicate frequency of pump-outs.
2. In NOI please answer for (7) regarding phasing differs from FEAF. Please clarify. Submit
NOI and SWPPOP preparer certification prior to construction and after final approvals.

3. Include concrete washout practice in question 26 of NO1.
4. In pre-development model node P-2 (existing retention pond) indicates an outlet pipe of
12-inches at 1.86% but survey map shows a 12-inch pipe 10' longer and at 1.56%. Please
clarify.
Plans
L-100
1. Can some of the trees around the existing and expanded detention basin be retained? If
construction access were turned more to the west it seems conceivable.
2. Move the concrete washout practice further away from drainage course and hopefully
retain some of the trees near that area.
L-200
1. What is top of wall elevation at southeast section of new tennis courts? Will it allow
runoff to escape, weeps proposed and detail provided? Is another wall proposed
between Greenburg Daycare facility/playground and court access path?
L-300
1. In northeast Bio-retention Area add two underdrain laterals that tee off main
underdrain. Revise detail to use 6-inch and specify perforation pattern with holes all
around circumference. Label inverts at capped ends and slope to DI-1.
2. Can proposed Hydrodynamic Separator accept the size pipe proposed and proposed
flow with existing runoff rates? Show size of pipe and inverts that diverts flow to unit.
Show elevations in details and verify unit size selected based on peak WQv flow and
bypass rates.
3. Add in underdrain elevations at capped ends and pipe slopes at southwest bio-retention
practice.
4. Add in elevation notes for SMP 3 similar to SMP 1 and 2.
L-400
1. Re-route 6-inch water main around bio-retention facility#3 to the east outside 392
contour. Should not be beneath practice.
2. Verify if steps need to be modified at existing sanitary manhole being connected to east
of building addition.

L-500
1. Add note requiring soil de-compaction with reference to SWPPP appendix so contractor
is advised on plan set of needs.
L-702
1. What is surface of dumpster enclosure floor that will receive significant dynamic forces?
Detail on plans with apron outside of enclosure on truck side.
2. Will wooden enclosure be all pressure treated and ultimately painted? PVC material?
L-703
1. Specify size and depth of rip-rap in detail 4. Pipes larger than 12-inches should be a mix
of medium and light rip-rap at least 18-inches in depth. Recommend stabilization fabric
instead of filter fabric as underlayment.
L-704
1. Increase pipe size in Bio-retention Area detail to 6-inch and specify perforation pattern.
Increase depth of stone layer to 8-inches.
2. Show elevations of all piping and rim for Hydrodynamic separator. See previous
comments on size of piping and flows tributary to it.
3. Specify sand component for bio-retention mix to be ASTM C-33 sand.
If you have any questions, please feel free to contact our office.
Sincerely yours,
BARTON & LOGUIDICE, D.P.C.
