Proposed Detention Basin Near Edgewood Drive and Bluebird Hollow
October 8, 2009
The Village Board of Trustees at their September 22, 2009 meeting approved the construction of the Edgewood Drive and Bluebird Hollow Detention Basin. Additional information, including starting contruction dates, will be posted as information becomes available.
September 18, 2009
The Village will be discussing several options at the September 22, 2009 Village Board meeting, including accepting the current bid; modifying the current bid; rejecting the bid; and rebidding the projected with a reduced scope of work. Please view Dolph Rotfelds notations on how a possible reduced scope will effect the Tree Protection and Removal Plan here.

In response to the July 15, 2009 Special Workshop, Dolph Rotfeld prepared a memo outlining potential cost savings for the Edgewood Basin project.

The Village of Rye Brook held a Special Workshop Meeting on Wednesday, July 15, 2009 at 7:30pm at Village Hall to discuss the Edgewood Basin project and the bid results, which can be viewed here.

Dear Rye Brook Residents:
On Monday, June 29, 2009 the Village publicly opened bids for the detention basin near Edgewood Drive and Bluebird Hollow. The following is a summary of the bids:
Company Name Bid Amount
Peter J. Landi, Inc.
The lowest bids are still considerably more than the $473,750 anticipated budget for this project, which includes $218,750 from a NYS grant. As a result, our engineering consultant, Dolph Rotfeld Engineering, is reviewing the line items submitted in the bids to see where costs exceeded the anticipated budget.
The Village Board will soon be considering the various options for this project, which will likely include the following choices:
1. Award the existing bid.
2. Seek additional grant funding.
3. Scale back the project scope and re-bid.
4. Do not proceed with this project.
These options, and possibly others, will be thoroughly discussed at a special workshop meeting of the Village Board to be scheduled in the near future at Village Hall.
The Village Board has also become aware of certain questions and concerns from residents regarding the blasting of rock anticipated as part of this project. This item will also be thoroughly discussed with our consultant at the special workshop meeting of the Village Board so that residents' concerns can be addressed prior to any potential bid award.
I invite all members of the Rye Brook community to attend any public meetings on this subject, and to continually check our web site at www.ryebrook.org for regular updates on this project and the time and date of the special workshop meeting.

June 16, 2009 Update:
The Village of Rye Brook is currently out to bid on project 09-10: "Edgewood Drive Detention Basin." The Bid opening date is June 29, 2009 with an expected award date at the Village Board meeting of July 14, 2009.
Please view the Negative Declaration and attachments adopted at the May 12, 2009 Board of Trustees meeting.
Please view the latest copy of the Landscape Plan and Grading Plan and Details for the Detention Basin.
This project was recommended in the November 7, 2002 report titled “Stormwater Analysis Eastern Branch Blind Brook” prepared by Dolph Rotfeld Engineering, which identified specific areas within the watershed to modify and improve, to reduce flooding within the watershed, control erosion, and reduce siltation of local ponds along the brook. This project is proposed for the implementation of controlling excess surface water resulting from construction development over the years. Excess surface water due to loss of open space is also contributing to downstream flooding. The proposed basin would be designed using state of the art approaches to reduce pollutant loading to the affected water bodies resulting in improvements to water quality. Measures will include detention of storm water, stream bank vegetative stabilization with appropriate plantings, and storm drain retrofit where appropriate and practical. Additionally, bank stabilization will reduce the introduction of nutrients from lawn chemicals due to over bank flooding. A draft work plan for this project was submitted to NYSDEC and was technically approved in February 2008.
The Village Board also held a special meeting on Thursday, October 2, 2008 in Village Hall to discuss this project. The consulting engineer presented the project and provided answers to several resident question concerning the project. You can view this video here.
At its regular meeting held on November 12, 2008, the Village discussed the proposed basin again to listen to any questions or comments. Residents were encouraged to attend, and meeting notice signs were placed on the site at Bluebird Hollow and Edgewood Drive. The Village also invited Lenny Myerson, Assistant Commissioner of the Westchester County Department of Health to addess and alleviate concerns with the West Nile virus and detention ponds; Dolph Rotfeld, who prepared more information on the level of water and properties positively impacted by the basin; and Marilyn Timpone Mohamed to discuss the preparation of the Environmental Assessment Form (EAF). For a copy of a Westchester County Health Department fact sheet on ponds, click here. This meeting can be viewed on streaming video from this web site. The next step is to further develop the conceptuial plans into construction plans for review by the Village Board. In order to proceed with this step, a detailed survey of the property will be completed.
The area tributary to the proposed basin is approximately 72 +/- acres. The installation of this basin would disturb approximately 1.6 +/- acres including the removal of trees. The highest water surface area would be 1.3 +/- acres (55,000 +/- SF), and the basin could hold an estimated maximum volume of about 8 acre feet which is almost 2.6 million gallons. The implementation of the proposed basin in this area reduces the peak rate of runoff for the 100, 25 and 2-year storm frequencies by about 49% on average at the pond and about 15% on average at the Acker Drive culvert.(Revised July 31, 2009)
Please view the Detention Pond Location Map #1 and Map #2. Please not these show location of project only, for lastest update on design please view the April 17, 2009 update above.
In considering this project, the Village Board will be weighing the changes to the proposed basin location (currently wooded) along with the benefits of water quality and flooding. To assist them on this matter, they requested that Dolph Rotfeld Engineering provide additional visuals of similar basins so that nearby affected residents will have a clearer understanding of how the area will view and be modified.
Dolph Rotfeld Engineering provided the following pictures of the following four (4) similar basins as described below.
- Eastview Office Park, Route 9A, Mt. Pleasant (20,000 SF): This detention basin was selected to demonstrate typical grading and planting of a basin. This basin has approximately 1/3 of the highest water surface area of the proposed basin.

- Mid-Westchester Executive Park (MWEP), Mt. Pleasant (40,000 SF): This detention basin was selected to demonstrate typical grading and planting of a basin. It has a surface water area that is double the size of the one at Eastview Office Park. It is similar in total volume but deeper than the basin proposed in Rye Brook.

- South West Executive Park (SWEP) North, Yonkers (46,625 SF): This detention basin was selected to demonstrate the typical grading and planting of a basin that is well maintained. It has a similar surface area to the MWEP basin.

- South West Executive Park (SWEP) South, Yonkers (120,000 SF): This detention basin was selected to demonstrate the typical grading and planting of a basin that is well maintained. It has approximately twice the water surface area of the proposed Rye Brook Basin.

The NYSDEC requested that the Village Board provide an additional resolution expressing their support of this project at this time. On August 12, 2008, the Village Board approved a resolution supporting the project, although the resolution has certain conditions allowing time for additional engineering information and additional public outreach prior to providing any final green light to implement this project. Please click here for a copy of the approved resolution.
