The Cone Zone: Week of Sept. 16, 2019

**Water Shut-Off Near NM502 Roundabout Project Next Wednesday Morning**

Weather permitting, water will temporarily be shut off for apartments and condominiums on Arroyo Lane on Wednesday, Sep. 18 from 8:00 a.m. - noon.  Construction crews will be tying this neighborhood into the new water system in support of the NM502 roundabout project.  

**SLOW DOWN IN & NEAR SCHOOL ZONES** 

Recently the County has received several complaints of speeding vehicles in or near School zones when children are walking on their way to/from school. This is an important public safety issue! Please, keep our children safe and slow down in these areas and neighborhoods bordering school zones.  

The Cone Zone for Wk of Sept. 16 

Public Works/Traffic Division projects:

Diamond Dr Paving 

Construction is wrapping up. The contractor will be finishing the paving at the San Ildefonso Roundabout over the weekend and early next week if needed. Final striping and marking of Diamond Dr is underway. Placement of concrete utility collars throughout Diamond Drive continues; motorists should expect lane closures for this activity. A portion of sidewalk south of Arkansas street on the west side of Diamond near the Mountain Elementary School access point will be replaced, resulting in a sidewalk closure and a driving lane closure. Pedestrians will be detoured to the east sidewalk. 

Drivers are asked to be patient and follow posted speeds. Work will continue Monday through Friday next week. The project is anticipated to be completed on September 27th. 

White Rock Crack Sealing Project Begins Monday

On Monday, GM Emulsion will be crack sealing roads beginning on Rover Blvd at SR 4 and continuing toward Grand Canyon Dr. They will continue down Grand Canyon Dr. starting at SR 4 to Meadow Lane. They will also work on Bryce Ave., starting at Rover Blvd to Meadow Lane.  Crews will be working from 8:30 am to 6:00 pm daily. The contractor will set up flagging operations to allow traffic flow. Weather permitting, work should be completed by September 30, 2019. The contractor will then return in mid-October to fog seal the same locations. Those residences and businesses impacted by the crack sealing work will receive information with daily schedules, coordination instructions and contact information as the project proceeds through White Rock. 

Curb/No parking zone/parking lot striping - locations vary 

Accustripe will continue striping curbs-no parking zones and parking lots throughout the County. Drivers and pedestrians are urged to follow all traffic control devices and maintain a safe distance from the painting equipment. Weather permitting, the project should be completed by September 25th.  

Roads, Sidewalk, Curb/Gutter work near Sioux, Alamo & Tsankawi Streets

Crews continue milling the shoulder on both sides of San Ildefonso Rd between Sioux and Alamo. Flagging operations are in place.  

In addition, GM Emulsion will be replacing sidewalks, curb, gutter and a drive pad on the south side of Alamo Road between San Ildefonso Road and Tsankawi Street. Pedestrians are urged to follow all traffic control signs.  

Motorists are urged to slow down and watch for pedestrian traffic within the work zones.

Other road construction projects: 

NM502 Roundabout and Road Reconstruction (NMDOT project)

See special water shut off alert above for Wednesday, Sept. 18. Otherwise, no change from last week's report. East-bound NM502 traffic detours onto 4th Street and Central Avenue. After a full stop, motorists turn right (east) and travel through the construction zone to continue east-bound out of Los Alamos on NM502. West-bound NM502 traffic entering Los Alamos and approaching the roundabout construction zone detours onto Central Avenue then west to Knecht Street then left to return to Trinity Drive. There is only one lane of traffic in each direction on Central Avenue. 

Project hours are 9:00 a.m. to 4:30 p.m. Monday through Friday. Please slow down, use caution and expect delays in this area, especially during peak commute times. 

Traffic advisories from NMDOT are available on www.nmroads.com and motorists are asked to check the site for updates on this project as it proceeds. 

TA-21 Clean Up Project - DP Road (N3B project):

No change from last week's report. Clean-up work on the LANL TA-21 Site at the far eastern end of DP Road continues. Large trucks carrying away demolition debris containers will be exiting DP Rd at an average of approximately three trucks per day. Motorists are asked to be alert for trucks exiting; use caution when entering or exiting DP Rd, as this area is near the NM502 Road Reconstruction project.

Oppenheimer Road Excavation

Macron Excavating, Inc continues excavating a section of road located near 557 Oppenheimer with a traffic lane shift in this area. The project is anticipated to wrap up by Tuesday. Motorists are urged to drive slowly through this work zone and watch for pedestrians.

About this page... This page provides citizens with basic information on County and non-County road construction projects. We are maintaining the page in the interest of keeping our citizens, visitors and commuters informed as a public service with one landing page where all information or links to information can be found.

About the Cone Zone...
The weekly Cone Zone report is posted here at the top of the page on Friday afternoons from March 8 through November 15, 2019, and then again from March through November 2020, in order to support public outreach especially for the NM502 Roundabout project, which is being constructed by the State of New Mexico's Department of Transportation over two construction seasons in Los Alamos. 

More about the State of NM DOT's NM502 Reconstruction & Roundabout Project...

Here is a project map showing projects in the area of NM502 and the roundabout/near DP Road which may cause additional traffic congestion heading into the busy summer months. Motorists are asked to use caution in this area. Staging for the equipment and infrastructure needed for the NM502 project (a fenced, secure area for Star Paving) is located on DP Road, as shown on this map.

Here is a project drawing showing what the NM502 Roundabout will look like when completed (furnished to the County by the State of NM DOT)

Due to utilities conflicts along NM502 for the new roundabout to be constructed, new storm sewer, retaining walls and grade changes associated with the new road design, infrastructure for water, sewer, electric, natural gas and fiber optics will be replaced and relocated as follows:

• Replace and relocate 2000 feet of water transmission line
• Replace and relocate 4500 feet of water distribution lines, including all service connections and fire hydrants in the corridor
• Replace and relocate 4000 feet of natural gas lines including all services lines in the corridor
• Replace and relocate 350 feet of sewer lines
• Replace and relocate 5000 feet of underground electric lines, including duct banks, conductors, transformers, vaults and all service connections in the corridor
• Replace and relocate 1400 feet of the fiber optic systems owned by Los alamos County and Comcast

Here is a link to the NMDOT webpage for all District 5 Proposed and Active Projects with additional information from the State. Scroll past all Proposed projects to the bottom of the page where you will see NM502 listed as an Active project. The State has posted additional information about roundabouts on this page, along with the March 20, 2019 public meeting presentation. The presentation shows many aspects and views of the construction project and detours that can be anticipated as it proceeds over the next two years. 

Nearby projects:
N3B - TA-21 Clean Up
N3B and their contractor will be working this year and next year on an environmental remediation/clean up project at the former TA-21 site (far eastern edge of DP Rd).

Here is a Fact Sheet about that N3B project which involves hauling away non-radioactive or low-level waste after properly packaging it in containers.

Infrastructure for Bethel Housing Developments - installation on or along DP Road:
Bethel Development's “Canyon Walk” apartments will be starting infrastructure and construction of new affordable workforce housing, scheduled to begin August 2019 with completion by August 2020. A second housing project by Bethel called “The Bluffs” on DP Road is also being considered and work could begin for additional Senior Housing. Both of these sites are referenced in the main NM502 project map shown above.

Future DP Road Infrastructure (long-term County project)
The County could begin installing infrastructure for the DP Road area in the future, as more land parcels become available and after TA-21 remediation is completed. These parcels are part of DOE Land Transfers that could be used for future light industrial or residential development. The infrastructure would extend to the TA-21 site as a "spine" for future development on the north and south side of the road. DP Road needs to be upgraded to include basic infrastructure that could be used by existing or new businesses or homes. For example, there is currently no sewer line in this area. The County applied for grant funding last year for offsetting these types of infrastructure costs for the DP Road project, but it was not approved.

What's next? A note about planned or possible future road projects:

Below is a listing of projects that motorists WILL or MIGHT see occurring in Los Alamos that might further impact NM502/Trinity Drive:

Canyon Rim Trail Underpass:
An underpass to connect LA Mesa trail underneath NM502 and south to the Canyon Rim Trailhead is wrapping up design stage and set to go to construction Spring 2020. It is located further east from the NM502 project. 

Work in Los Alamos on various projects by the County or by others may get underway in 2019 or 2020 that might cause some traffic slow-downs:

Trinity Drive:
In June, the State DOT announced that they have secured funding to do much-needed roadway, curb and gutter repairs on Trinity Drive, from Diamond to the eastern edge of Los Alamos. Work could get underway in August or September; we are awaiting further updates from the State. A portion of the work would involve a "road diet" near the turn off to the former LASO building site (now expected to become The Hill apartments with construction beginning soon.)

There could be several projects occurring over the next two years while NM502 is under construction at the eastern edge of Los Alamos:

Construction on a new business set to occur at the 20th Street (all six pads) lot - to be announced in August

Traffic light installation at 20th and Trinity Drive once the new business listed above is constructed.

New business construction along Trinity Drive (Natural Grocer is expected to build a store at the Shriner's Club lot)


SR4/Truck Route intersection:
This has been a high-profile project for several years - there are design plans in progress but no funding set aside for construction. At this time, and because of the impact that will already occur for increased traffic on SR4/Truck Route during the NM502 project for two years, it is not anticipated that there would be road work on the intersection at the same time.

Watch for updates on this page for Future Projects such as the ones listed above, or, for new projects to be added as they are identified. As the County gets more details, updates will be posted here.


SHOW YOUR SUPPORT, LOS ALAMOS!
Construction can be difficult and present special challenges for businesses caught in the construction zones and related/adjacent areas. Motorists tend to avoid orange barrel zones and this can have significant economic impacts on businesses. Los Alamos has many small, locally-owned and operated restaurants, specialty shops and stores on the eastern edge of Los Alamos. The County encourages residents and visitors to support local businesses, especially those on DP Road, which will likely be impacted by the construction. Other businesses at Entrada Business Park, East Gate, along Trinity/Knecht (Mari Mac and Smith's Marketplace and further west on Trinity) as well as those on Central Avenue may likely be impacted, too. The County is working with MainStreet and the Chamber of Commerce to find ways to mitigate impacts and support them, but your help is urgently needed! Allow extra time for patronizing these businesses, but please don't shy away just because of construction! They need your help to continue to operate all of your favorite and valued restaurants, shops and other small businesses to be able to provide you great products and services.
