Official Communication from the Town of Lyons

Proposed Draft Floodplain Mapping

Following the 2013 flood, the Colorado Water Conservation Board (CWCB) initiated a program to re-map the predicted 1% chance regulatory floodplain (100-year flood zone) of the most affected waterways. The program was named the "Colorado Hazard Mapping Program" or "CHAMP".
The CWCB draft floodplain maps will reflect changes to waterways caused by the 2013 flood and the recovery work since that flood. They'll also utilize more accurate data and advanced technology than was available when the current maps were created. As a result, the CWCB draft maps will be a more accurate representation of the anticipated 1% annual flood elevation and therefore more precisely reflect the flood risk for residents than the existing regulatory floodplain maps. 

Town of Lyons Draft Floodplain Maps

The Town is currently reviewing the proposed new floodplain maps, within Town limits. The working draft floodplain map, as well as the current (2012) FEMA-adopted map, can be found here.

Town of Lyons Snow Response Plan

Snow Removal

Please remember that in accordance with the Lyons Municipal Code, property owners must remove snow or ice within 24 hours after the last accretion. If sidewalks remain hazardous and unkept, the Town will mitigate and charges will be sent to the property owner. 

Lyons Municipal Code, Sec. 11-1-50:
It shall be unlawful for any owner or occupant of any lot, block or parcel of ground within the Town, or for any agent in charge of such property, to allow any snow or ice to accumulate or remain upon any sidewalk alongside such property longer than twenty-four (24) hours from the time of the last accretion of such snow or ice.

Thank you for your cooperation in maintaining a safe environment!

Storm Water Master Plan

The Town recently completed Storm Water Master Plan, funded by a CDBG-DR grant from HUD.

This plan updates a previous plan completed in April 1998. In addition to the basic updates of that plan, this plan modernizes the techniques used for runoff determination at various storm events, introduces concepts of updated codes and standards, water quality treatment of runoff, identifies areas at risk for flooding or inundation during various runoff events, identifies large scale capital improvement costs for the major runoff basins, identifies alternatives that could be considered in developed and undeveloped areas of the Town and adjacent unincorporated areas of Boulder County, and other important elements of a storm water master plan. 

This plan will be a useful tool for the Town of Lyons Board of Trustees and Staff to help prioritize and identify capital improvements and to inform land and homeowners of issues and concerns related to their property; for landowners and business owners to understand and be informed of the conditions of the storm water runoff; and for developers to understand issues and constraints and potential capital investments related to projects and development. Consultants will be on hand to discuss the plan. 

Feedback submission and versions of the draft plan, including PDF and an interactive map are available here.

2017 Lyons EcoPass

Great news! The Town of Lyons, with the support of Boulder County, has renewed the community EcoPass program for 2017. This program provides all Lyons residents with a bus pass for RTD’s front range bus and light rail services. The only change to the program from previous years is that there will now be a small annual fee for the EcoPass that will be due before the end of March 2017. While the cost of the fee is in the process of being finalized, users can expect the annual fee to be between $25 and $50, with exceptions. Some exceptions may include discounts for students, elderly, and low income residents. The pass has a retail value of over $2,000.

More details of the program, pricing, and the purchasing process will be determined and announced in early 2017.  Until then, current EcoPasses will automatically renew in the New Year. 

For more information, visit the Town's EcoPass Page, or contact Sustainability Coordinator, Toby Russell at 303-823-6622, ext. 46.

Impacts of Fats, Oils, and Grease in Drains

A message from the Utilities and Engineering Board

The Lyons Utility and Engineering Board would like to emphasize the importance of not putting Fats, Oils or Grease (also known as FOG) and Food Scraps or any Plant Matter down your drain. Processing FOG at our wastewater treatment plant increases the cost of running the plant. Food scraps should be composted - not put through a garbage disposal. FOG should be disposed of in a sealed container into the garbage. Please help keep our utility bills from going up and our new wastewater plant running at less cost.
