Update 9/21/2018:

The project is complete.

Project Notes Status update 9-20-2018

Update 9/14/2018:

Notice of Water Outage

due to Repairs Planned for September 18 to 20, 2018

The planned pipeline repairs, located near Mount Vernon Country Club Road and Chief Hosa, are scheduled to start on Tuesday, September 18th and are planned to be substantially complete by Thursday, September 20th.  As always, LMWD will do its best to reduce service interruptions to you, the customer*.  Unfortunately, it is not always possible to avoid service interruptions given our pipeline ages, conditions and locations.

The longest outage is estimated to occur during the hours of 9 a.m. to 4 p.m. on Tuesday, after which temporary water is planned to be delivered via a connection from Genesee Water & Sanitation District (GWSD). This replacement water is only for domestic use (it is unable to provide fire flows) during the planned repair days on Tuesday and Wednesday.  There may also be a brief outage while Genesee water is taken offline and LMWD water is restored once the pipeline repairs have been completed.  We ask that all customers be conservation minded while using Genesee water on the 18th and 19th.

Customers should expect service interruptions estimated to last from 4 to 8 hours (or more) any time on these three days due to factors or emergencies beyond our control.   PLEASE PLAN ON INTERMITTENT WATER OUTAGES, PRESSURE VARIATIONS, BUBBLES, CLOUDY OR DISCOLORED WATER STARTING SEPTEMBER 18TH.  HOW MUCH AND HOW LONG YOUR SERVICE IS AFFECTED WILL DEPEND ON YOUR SERVICE LOCATION RELATIVE TO THE LOCATION OF THE REPAIR AND THE TEMPORARY WATER SUPPLY.

*Customers and fire hydrants to the west of Chief Hosa will not be affected by this water outage.

The leak repair on the main that started in August is only temporary—it revealed a failing pipeline with another nearby leak. A permanent repair/replacement and valve installation is pending. From this location (near Chief Hosa Campground and Spring Ranch), the main supplies about 95% of all customer taps and  hydrants. Our kind neighbors at Genesee Water & Sanitation District have agreed to supply temporary water. However, not all service interruptions can be completely avoided during the 6 to 10 days of construction.

If you would like email notifications about this upcoming outage and are not already on our list, please write sfletcher@blacklockintegrated.services or call 303-526-2025 x101.

Status report on 9/8/18 (Copy of follow-up Email notice to first email notice 4 pm 9/7/18)

Last night’s temporary repair is holding for now so all of you should have water at this time. There is nothing more that can be done until Monday morning when LMWD staff can work with parts suppliers and contractors.

PLEASE PLAN ON INTERMITTENT WATER OUTAGES, PRESSURE VARIATIONS, BUBBLES, AND POSSIBLE DISCOLORED WATER AS THIS IS NOT A PERMANENT REPAIR AND IT COULD FAIL AT ANY TIME.  For further information, please refer the Notice sent to you in the newsletter provided with your August bill. This aging pipe is quite expensive to replace and will result in extended water outages, which is why it has not been completed previously.

Would everyone please let your neighbors know (those with no email or those who don’t check it frequently).  Now is the time to capture some water (fill your tubs, buckets, pitchers for drinking and cooking).  Most toilets can be flushed using a 2 gallons from a bucket.

We will issue another email next week if status changes significantly or improves.  Thanks everyone.

Risk Reduction Spillway and Dam Safety Modifications at Lower Beaver Brook

Comments Off on Risk Reduction Spillway and Dam Safety Modifications at Lower Beaver Brook

Project Summary, Status Update, and RFP – July 2019

The Lookout Mountain Water District (LMWD) has received assistance from FEMA to address identified dam safety deficiencies at the Lower Beaver Brook Dam, pursuant to the National Environmental Policy Act (NEPA), Section 106 of the National Historic Preservation Act (NHPA), Executive Order (EO) 11988 – Floodplain Management, and EO 11990 – Wetland Protection, and Federal agency implementation procedures, including 44 CFR Part 9 and FEMA Directive 108-1.

FEMA funding will be provided through the Pre-Disaster Mitigation Program (PDMC-PJ-08-CO-2017-002), which provides funds for the planning and implementation of long-term hazard mitigation measures prior to a disaster event. The purpose of the PDM program is to implement cost-effective mitigation projects that will reduce the overall risk to populations and property.  In accordance with NEPA, an Environmental Assessment (EA) was prepared to evaluate the potential impact of the proposed project on the human and natural environment and has issued a Finding of No Significant Impact (FONSI). Appropriate mitigation measures will be implemented in accordance with EO 11988 and Section 106 of the NHPA.

The proposed project includes addressing the identified dam safety deficiencies at Lower Beaver Brook Dam by replacing the existing 114-year-old rockfill embankment dam with a new concrete gravity dam. The proposed Lower Beaver Brook Dam will be designed and constructed to be in conformance with the State of Colorado Division of Water Resources, Dam Safety Branch Rules and Regulations for Dam Safety and Dam Construction. The new concrete dam will be constructed immediately downstream of the existing dam and will not result in additional storage capacity or increased discharges during routine flow conditions.

Project Summary and Status Update – March 2019

The Lookout Mountain Water District continues to work on the Lower Beaver Brook Dam Safety Modifications Project. The District applied for grant funding of $3.9 million for the project through the national Pre-Disaster Mitigation Program. The purpose of this program is to implement cost-effective mitigation projects that will reduce the overall risk to populations and property.  The dam is over 100 years old and its spillway is undersized, so it must be replaced to ensure that the District will have a secure supply of water for the treatment plant and to reduce risk of failure during flooding. District residents will be responsible for funding the remaining cost of the project (current estimated total project cost is $5.3 to 6.2 million).

FEMA has issued an eligibility notice in 2018 and expects to award the grant in mid-2019, then design and permitting can be completed in 2020 with construction to follow in 2021.  The project is currently under review for environmental and historical preservation.

Primary Participating Agencies —

Federal Emergency Management Agency  (FEMA)

Colorado Division of Homeland Security and Emergency Management (CDHSEM)

Colorado Division of Dam Safety

Colorado State Historic Preservation Office

Colorado Water Conservation Board

U.S. Army Corps of Engineering

Jefferson and Clear Creek Counties

 

PRE-DISASTER MITIGATION PROGRAM FUNDING

FEMA is considering funding a portion of the proposed project through the Pre-Disaster Mitigation Program (PDM), which provides funds for the planning and implementation of long-term hazard mitigation measures prior to a disaster event. The purpose of the PDM program is to implement cost-effective mitigation projects that will reduce the overall risk to populations and property.  In accordance with NEPA, an EA will be prepared to evaluate the potential impact of the proposed project on the human and natural environment.  A portion of the project will be funded by LMWD. The State of Colorado Office of Emergency Management will oversee the administration of the grant funding.

DAM SAFETY SUMMARY

The proposed project includes addressing the identified dam safety deficiencies at Lower Beaver Brook Dam by replacing the existing 114-year-old rockfill embankment dam with a new concrete gravity dam. The modified Lower Beaver Brook Dam will be designed and constructed to be in conformance with the State of Colorado Division of Water Resources Dam Safety Branch Rules and Regulations for Dam Safety and Dam Construction. The existing 114-year-old rockfill dam will be removed in stages throughout the construction of the new concrete dam.

The new concrete dam will be constructed immediately downstream of the existing dam. The new concrete dam will have a non-overflow dam crest at each end, with a central emergency spillway. The existing service spillway on the right abutment will be rehabilitated to maintain the existing normal pool elevation of about 7837.7 because maintaining this normal high-water line is important for maintaining water storage for drought protection, operation of the Water Treatment Facility, and for avoiding long-term environmental impacts to habitat and wetlands in the reservoir area. The new structure will not result in additional discharges in the downstream floodplain during routine flow conditions.

Leak Repair Status Update 08-20-2018

Comments Off on Leak Repair Status Update 08-20-2018

The leak repair on the main line started on 8/13/2018 is temporarily complete and water has been restored to all locations.   Some locations may experience cloudiness, discoloration or pressure variations, due to air being introduced into the lines and sediment disturbances, which could last for multiple days.  All safety procedures were followed as usual and water is clean.  Please consider watering plants to get this discolored water out of your lines.

Unfortunately this repair revealed a failing main line, a nearby leak and other complications related to buried utilities in the area.  District Board and staff is preparing to address this matter so that a permanent line replacement can take place (about 100-200 feet). Notice for the permanent repair will be issued, however, the District will be watching this area for a unscheduled failure which could result in an unplanned water outage.

The leak location is near the Chief Hosa Campground/Spring Ranch. From this location, the line supplies about 95% of all customer taps and hydrants.
