Left Hand Brewing has formally submitted their application for their cultural event center. Here are the supporting documents (click on the pictures below to open and read).
While this application does not ask for a variance from the 150 foot conservation buffer along St. Vrain Creek, of particular concern are the noise levels measured by Left Hand’s consultant. Per typical concerts put on by Left Hand at Roosevelt Park, the decibel level at the back of the venue may average 95 DBA, though this level may fluctuate up and down.
Sound levels fall off the farther from the source you get. However, the consultant estimated that sound levels across the river to the south at the nearest homes could be as high as 77 DBA. For comparison, a concrete mixer 50 feet away has a DBA of 80, while a large dog barking 50 feet away has a DBA of 70.
Currently, Longmont has a noise ordinance in chapter 10.20.110 of the Longmont Municipal Code that prohibits noise levels higher than 55 DBA during the day and 50 DBA during the night in residential areas unless a special event permit has been issued. Because Longmont does not have any ordinances dealing with music events at designated venues, Left Hand will almost certainly be seeking to change the noise ordinance.
If anything about this application concerns you, please send your comments regarding the cultural event center application to City Planner Brien Schumacher. He can be contacted by calling (303) 651-8764 or by emailing Brien.Schumacher@longmontcolorado.gov. There will very likely NOT be a second neighborhood meeting.
