Flood Update 5/11/2018

We received the following letter from NHDES regarding their visit to view the flooded areas from the storm of October 30, 2017:


Mr. Chandler, Mr. Patch, Ms. Garland, and Chief Roberts –


At the link below, you will find the site visit summary for the Saco and Rocky Branch Rivers that you requested.




Please let me know if you have any trouble accessing the document.


The summary, with pictures, was written strictly from the perspective of the fluvial geomorphologist, and describes the current river processes operating and their implications on infrastructure. Technical options for you to consider are also included, with discussion of their process implications should you choose to consider and undertake any of them. Your engineer on retainer can provide you design guidance and provide you information on involved costs.


Additionally, from the perspective of a floodplain manager, additional mitigation options relative to the properties we visited are available should you choose to consider them. As referenced in the report, the two properties directly downstream of the railroad crossing we visited will continue to experience flood inundation at the level of flows experienced during Irene or last October, irrespective of geomorphological factors. Mitigation projects such as elevating the buildings, or even acquisition can be considered. Personnel from HSEM and Jennifer Gilbert (NH OSI) can assist you with these if you choose to pursue them. Such options could be future considerations for the other property that we examined on the site visit if structural options with the river, as discussed in the summary, are not undertaken on the Saco River, and the flood chute system south of that house were to evolve as potentially described.


Hope that you find this information, and that contained in the fluvial geomorphology summary, helpful. If I can be of further assistance to you on issues related to the Saco or Rocky Branch Rivers, or have questions about the summary, please feel free to contact me.

Kidde recalls dual sensor smoke alarms due to risk of failure to alert consumers to a fire

Kidde is recalling its dual-sensor (photoelectric and ionization) smoke alarms – models PI2010 and PI9010. “KIDDE” is printed on the front center of the smoke alarm. The model number and date code are printed on the back of the alarm. A yellow cap left on during the manufacturing process can cover one of the two smoke sensors and compromise the smoke alarm’s ability to detect smoke, posing a risk to consumers not being alerted to a fire in their home.

Consumers should remove the alarm from the wall/ceiling and visually inspect it through the opening on the side of the alarm for the presence of a yellow cap. Consumers should not attempt to take apart the alarm, open the casing, or otherwise remove the yellow cap themselves. If a yellow cap is present, the consumer should immediately contact Kidde to receive instructions and request a free replacement smoke alarm.

Consumers should remove and discard the recalled smoke alarm only after they receive and install the replacement alarm. If no yellow cap is present, consumers should reinstall the smoke alarm and no further action is needed. About 452,000 were sold in the U.S. Consumers can contact Kidde toll-free at 833-551-7739 from 8:30 a.m. to 5p.m. ET Monday through Friday, from 9 a.m.to 3 p.m. on Saturday and Sunday, or online at www.kidde.com and click on “Product Alert” for more information.
