Lake Flood Protection
(The following paragraph is an excerpt from the Lakes & Grounds Committee report printed in the August 2006 Greystone Village Voice newsletter)
The Lakes & Grounds Committee is presently engaged in the evaluation of our flood control system, which includes our three lakes and their associated dams and connecting streams. We were hit pretty hard by the remnants of tropical storm Alberto, which dropped more than seven inches of rain in very few hours. Many of our streams were flooded and the dam at Winchester Lake has undergone some severe damage to its spillway. The board called a special meeting in June to deal with these problems. At that meeting, we appropriated funds to fix the spillway, which, if left in its present condition, could lead to dam failure. These repairs will be undertaken by the end of July and are the first phase in our evaluation of the system and its long-term health.
Flood Protection Status Updates, 2006
Dan Brubaker, City Project Manager and Stormwater Engineeer for the City of Raleigh, is negotiating a contract with an engineering consultant to look at the spillway and house flooding and water quality issues on Greystone Lake. Early in the process, they plan to hold a meeting with the neighborhood to gather their input. Dan will provide Nancy McFarlane, our HOA Board President, with additional details and a schedule once they complete the negotiations for the design contract. That information will be posted on this web site.
With regards to the entire lake system, we have received one bid from an engineering firm and we are currently seeking two more bids from other engineering groups. We hope, with the help of a qualified engineering firm, to develop a finite plan for the care, development and maintenance of the lake system in Greystone.
Lake System Drain Valves and Flood Control
Under the guidance of Foster Lake & Pond Management, Inc., the Greystone HOA Board Members have learned that lake system drain valves are typically not opened for flood control. The reasons for this were presented to us by the lake management experts at Foster:
There are additional issues regarding the design and location of the drain valve that make it difficult to reach and unlock the valve, particularly on short notice. Therefore, our flood control experts have adopted a policy of strongly discouraging the practice of opening the valve for flood control. If a client (such as Greystone) insists that the valve be opened, the lake management company requires the client's signature on an agreement that identifies their reasons for discouraging the procedure, limits their responsibility or liability for damage and explains why their significantly higher fee for the activity is justified. All of this may place the Greystone homeowners at serious risk and great expense.
