SNOW!

Deicers and Sidewalks

If you remember your days in chemistry (I don’t), salts are combinations of anions (negatively charged particles) and cations (positively charged particles). Examples are sodium chloride (table salt), potassium chloride (used as a fertilizer) and magnesium chloride (the one you see trucks spraying on our roads). The most problematic element in these salts is chloride…it’s a corrosive ion that damages metal and concrete and is toxic to plants.

Salt damages plants by dehydrating plant tissues (causing burn) or by being toxic in high levels. While most plants have some tolerance to salt injury, repeated applications of deicing products during the winter can result in dieback or even death the following spring. Misapplications of deicers (i.e. dumping piles or using too much) can wash into the storm sewers, causing pollution. Before buying or using any product, read the label carefully and thoroughly and use only as directed.

Sodium chloride: It’s the most widely available and the cheapest. It doesn’t cause corrosion to concrete, and melts ice best when temperatures are in the 20s. It is the most damaging to plant material. If you use this product, use sparingly and in small amounts.

Potassium chloride: Our salty fertilizer friend. It’s expensive and not as widely used as a deicer because of rising costs of fertilizer. Works best when temperatures are above 15 degrees F. Because it’s most commonly used as a fertilizer, it’s relatively safe to apply near plants.

Magnesium chloride: Good ol’ mag chloride. It’s the most common product used on our roadways before storms (applied as a “brine”), because it lowers the freezing point of soon-to-arrive precipitation. It can melt ice down to -15F, which is a nice benefit. If applied in moderate amounts, it’s relatively safe for plants and pets. Its corrosion potential is low, as is its pollutant possibilities.

Calcium magnesium acetate (CMA): A new kid to the deicing block, it has low corrosion potential, so it’s less damaging to cars, metals, sidewalks and plants. Notice it’s not a chloride product…the “salt” comes from the calcium-magnesium mix and the acetate replaces the chloride.  Plus it’s biodegradable! Its ice-melting properties are equivalent to traditional deicers, but the cost will make you gasp…it may be 20-30 times as expensive as sodium chloride products.  These are often touted as “pet friendly”.

Before using any product, clear away as much snow and ice as possible. Get out your shovel and do your best. If heavy snow is predicted, then try to shovel more frequently. Remember, deicing products are not meant to melt all snow in and ice, but aid you in your removal efforts. If you want to avoid chemistry in your landscape, then consider using sand or kitty litter. While they don’t melt snow, they can provide some much needed traction in slippery spots. Sand and kitty litter are also safe for pets and plants and can be swept up when the snow melts.

cherrydaysThe Town’s Right-of-Way (ROW) includes the streets, alleys and area between the curb and private property line.  The ROW is used for underground and overhead utilities, public sidewalks and mailboxes.  The vegetation in this area is the responsibility of the property owners.  Trees in this area must be maintained to not interfere with traffic or pedestrians.

Sidewalks are required for all new construction.  The maintenance, snow removal and installation is the responsibility of the adjacent property owner.

The Public Works Department is responsible for efficiently maintaining safe driving conditions on almost 100 lane miles of concrete, asphalt, and gravel streets.

Maintenance of these numerous miles of streets consists of: the repair and maintenance of the street pavement (concrete, brick, asphalt, and gravel) and curbs, bridges, drainage culverts, pedestrian and school crosswalks, installation and repairs, traffic control and signage, pavement markings, street sweeping, mowing and noxious weed control of public right-of-ways and properties, grading, ice control and snow removal operations, storm damage and cleanup, traffic control for emergency services and Town Board approved community events.

Public Works is also responsible for maintaining alleys. Maintenance of the alleys is performed by grading and applying gravel where needed.

Our Staff is dedicated to public safety on our streets, alleys, and public owned properties performing these services in a consistent, safe, reliable and cost effective manner. We strive to serve our community and promote quality services through open and honest communication.

zephryos_water_1The Town’s Water Department has responsibility for all activities related to the delivery of drinking water, including storage (water tower), pumping stations, and water mains. We are also responsible for planning, establishing, and overseeing the construction of new water system improvements.

As the Town’s ORC (Operator in Responsible Charge), Travis Loberg is responsible for managing the Town-wide water and sanitary sewer systems.

Currently, the Town of Paonia is in the process of constructing approximately $5.4 million dollars of water system upgrades and enhancement projects. Please refer to the Town’s News postings for more information concerning these projects and for regular project updates.

 

The Town of Paonia’s Sanitary Sewer and Wastewater Treatment Facility has responsibility for wastewater collection and the operation of the wastewater treatment plant.

Paonia’s current Wastewater Treatment Plant was built in 2007. The WWTP is a lagoon treatment system with a finishing pond. The Town of Paonia’s Wastewater Treatment Plant is a State of Colorado Class C facility. Daily and weekly testing for pH, TSS, BOD, conductivity, ammonia and nitrate is performed by the staff.

The plant has averaged 495,000 gallons per day since start up in 2007.
