Dear CLRC members and friends,


Construction of the new bridge, channel and park at Garrison Street is expected to start mid-to-late October, but the initial construction work will be limited to some utility work on Garrison Street and along Brooks Drive.  According to the City’s engineering staff a water main replacement will likely close Garrison Street for a couple of weeks, but the major dirt moving work will not start until December or January.  The anticipated closure of Garrison Street to build the new bridge has been pushed back to February.  That closure is expected to last for six months.


The popular Santiago’s Mexican take-out restaurant next to the bridge is scheduled to close before the end of September.


Haul routes have not yet been determined for the rechannelization project.  Approximately 80,000 cubic yards of embankment material must be hauled from the site of the new park to make room for the new drainage channel.  That’s about 13,000 dump truck loads passing over residential streets or pulling out into traffic on Ralston Road and then returning for another load.  The new Arvada K-8 park can take about a quarter of that dirt, but, as of now, the rest of the excavated material has no place to go.  When asked about the number of trips required to move that excavated material, project engineer Mark Floyd said, “. . . that, frankly, is my major concern in this whole project.”



The Citizens for a Livable Ralston Community will post more notes online on its website at as information becomes available.


Or, check out the project’s engineering plans on the US Corps of Engineers website.   There is a separate CLRC News article that covers the City’s Section 404 Permit application.  That article also has a link for downloading the project’s drainage and landscaping plans.
