LL C* <br />1tY0 <br />Louisville <br />I W, I Y. ��oI:10 to) ►1 <br />Memorandum <br />To: Open Space Advisory Board <br />From: Ember Brignull, Open Space Superintendent <br />Date: October 14, 2020 <br />Re: Staff Updates <br />Trails & Maintenance: <br />1. The Open Space Division submitted an application for a trails maintenance grant to <br />resurface and repair the Davidson Mesa trail through the Colorado State Trails <br />Program. The City requested the maximum total of $250,000 to help fund the <br />project. Staff submitted the application on October 1, 2020, and it is under <br />evaluation by the grant committee's review board. <br />2. Open Space is in the process of hiring an Open Space Maintenance Technician to help <br />aid the existing position with its responsibilities. Staff has assessed applicants for the <br />position and have narrowed the selection down to five strong candidates. <br />3. City staff has been delivering water for crop irrigation from Hecla Lake to Harney <br />Lastoka farms since May 2020. This process is a multi -municipal program involving <br />City of Louisville, Boulder County and City of Lafayette. In the late or dry season, <br />water is delivered to Hecla Lake through a pipeline running from the Central Big <br />Thompson watershed to Hecla Lake. The water is then released out of Hecla Lake by <br />City staff and delivered to Harney Lastoka farm through an underground pipeline. <br />The pipeline runs under South Boulder road to the farmer's ditch. The water is <br />carefully regulated and monitored to keep Hecla Lake water levels safe for the <br />surrounding habitat and the farmer's water shares fulfilled for the year. <br />4. The repairs to the water -damaged section of the Coyote Run Trail, east of <br />Washington Ave were completed on September 30, 2020. The process involved <br />scraping the trail down to the landscape fabric, replacing the old or no longer existing <br />areas of fabric and re -grading the trail. Staff removed any vegetative material, and <br />mixed new crusher fine with the existing material and graded it with proper slope <br />and cross -slope. After that, staff used a hotsy trailer to spray the crusher fines to <br />make the material damp. Finally, with a 1-ton vibratory roller the crusher fines were <br />compacted into place. <br />7 <br />
