j. Wetland Mitigation Plan, North Ridge Street Development revised February 28, 2019,
We revised the Construction Management Impacts and Logistics Plan and the Sight Distance Study
(sheet 4A above) since our last submission to the Village Planning Board. The Wetland Mitigation
Plan is new and addresses the disturbance of a portion of the wetland buffer on Lot 3.
We reviewed the Planning Board’s Resolution “A Report And Recommendation To The Rye Brook
Board Of Trustees On An Application By Lou Larizza For Approval Of Zoning Map Amendment, 3-
Lot Subdivision And Site Plan For Affordable Housing On Property Located At 259 North Ridge
Street Dated March 14, 2019”. The Resolution was divided into ten (10) segments.
We offer the following additional information for the Board of Trustees on the content of the ten (10)
segments of the Planning Board Resolution as follows:

2 North Ridge Street Development
1 Traffic and Site Access.
Traffic Volume/Vehicle Trips
Response: On this project we are not constructing any new roads, merely 3 new
driveways and it is not clear whether the AASHTO standards must apply here.
The Planning Board asked us to provide data using 40 miles per hour as the
design speed. At the 40 mph design speed, which is 10 mph over the posted
speed limit, the specialized parameter noted as “Intersection Sight Distance”
has minor shortcomings meeting the AASHTO standards for new road
intersections at Driveway 1A (South), and Lot 3. It is difficult to equate a new
road with a driveway as the latter has such a low volume of traffic.
However, at the 40 mph design speed (which is a speeding violation) all of the
“stopping sight distances” comply with AASHTO standards. In other words,
any driver traveling at 40 mph would have adequate time to stop upon seeing
another vehicle stopped in the roadway.
Partial Conformance Table of Sight Distances for 40 Miles per Hour Exceeds Speed Limit
We provide additional sheets to show that the every driveway has sufficient
stopping sight distance for vehicles at the posted speed limit of 30 miles per
hour (see below).
Again, at the posted 30 mph design speed, all intersection sight distances and
stopping sight distances comply with AASHTO standards for new road
intersections.

3 North Ridge Street Development
Improvements to Intersection of North Ridge Street and West Ridge Drive.
Response: There are, currently, channelizing pavement marking
improvements at West Ridge Drive. The applicant is not
proposing any further improvements or reconstruction to
the intersection.
Sight Distance.
Response: As stated above, additional sight distance plans are provided for the posted 30
mph design speed.
2. Utilities.
Response: The applicant is exploring the various utilities as most utilities are existing in
North Ridge Street.
3. Stormwater Management.
Response: The stormwater plan has been reviewed by the Village Consulting Engineer
and further refinements may be required based upon a final version of the site
plan as approved by the Village.
4. Tree Preservation & Protection Plan and Planting Plan
Response: The replacement plantings meet the requirements of Chapter 235 and the
proposed plantings will not interfere with sight distance.
5. Wetland Buffer Disturbance
Response: The Wetland Maintenance Area is to be purged of non-native and invasive
vegetation and replanted to contain enhanced wetland plantings that will
increase the function of the wetland as shown on the Wetland Mitigation Plan
included herewith.
6. Steep Slopes
Response: The subdivision and Site Plan currently shows the minimal amount of
alteration of land and topography that is necessary.
7. Visual Impacts & Scenic Road Overlay District
Response: The views of the structures and the proposed walls from Eagles Bluff are
mitigated to the maximum extent practicable. The view provided to the
Planning Board was an accurate indication of the view from Eagles Bluff.
8. Construction Management
Response: The construction of foundations, placement of fill, site work and construction
of driveways have been added to the CML revised May 1, 2019.

9. School-Aged Children
Response: The Planning Board has agreed with our estimate of school aged children and
that the number is a reduction from previous proposals.
10. Zoning Petition (R-l5 to FAH)
Response: The Planning Board has no objection to the rezoning of Lot 1 to FAH.
III. RECOMMENDATIONS
Response: The Planning Board recommended the Board of Trustees approval of the
Zoning Petition, the 3-lot subdivision and the Lot 1 Site Plan applications.
Accident History:
From the Village of Rye Brook Police Department we obtained accident records along North Ridge
Street. Our office went over all of the records for the period from July 2014 to March of 2019.
In that time there was one (1) accident
somewhat near the proposed site and
none along the frontage of the property.
The traffic count data from April 2016
suggests that in that study period there
were about 10 million cars that passed
the site.
We are requesting the Village Board approve the Zoning Petition, the 3-lot subdivision and the Lot 1
Site Plan applications as the review has been extensive and we have addressed all comments of
the Village Planning Board and the Village consultants.
The above information is submitted for the May 14, 2019 meeting of the Village Board.
Sincerely,
Ralph G. Mastromonaco, PE
