Off Site Improvements

Any work or activity within the public right of way is considered an off-site improvement. That is, if anyone is digging, constructing, or doing any work on Public Street, sidewalk, curb or gutter or any underground work within the public right of way such as sewer, curb drains, etc.; these are considered off-site improvements. Any off-site improvement or any activity within the public right of way requires an excavation permit from the Public Works Department. Encroachment permit fees are also required and vary depending on the type of work being done.

For further information, please contact Public Works Engineering Division Monday thru Friday from 8:00a.m. to 5:00 p.m., at  (719) 846-9843 ext 125.

Maintenance Techniques

Concrete Repairs
Streets and Bridge personnel are responsible for some curb and gutter repair, bridge repair, and concrete street and alley maintenance. Crews assigned to this activity also assist during major rehabilitative projects.
Asphalt Repairs
Asphalt maintenance functions such as partial and full depth patching, pothole repair, and surface seals are performed by this activity. Additionally, personnel assigned to asphalt repair also assist in larger projects such as street rehabilitation and reconstruction projects.
Crack Sealing
Repairs consist of using a polymer modified sealant intended to seal cracks in asphalt to prevent moisture from seeping below the surface level and into the base. Infiltration of water into the base level ultimately leads to a debilitated base structure. This preventive measure is normally applied during the spring and fall season.
Seal Coating
This is not a permanent maintenance process. The service life of seal coats on average is 5 to 7 years depending upon traffic volumes, weather, and construction techniques, etc. Seal coats are capable of preventing and correcting a variety of maintenance problems, such as small cracks, ravelling, and flushing. Seal coats can seal existing pavements against the penetration of air and/or water, thus reducing pavement oxidation, and can enrich a dry and/or ravelled surface. Seal coats can also provide or improve skid resistance qualities of a pavement surface as well as arrest fatigue block deterioration. Favorable weather conditions are important because inclement weather (cold, wet), particularly in combination with high-volume traffic, can be detrimental to seal coat construction and performance. 
Gravel Maintenance
Streets and Bridge personnel are also tasked with the maintenance of all public gravel streets and alleys.
Street Rehabilitation
Typically the Engineering Department will design and bid the street overlay projects.  The Streets and Bridge department assist in identifying the locations for the up coming years overlay and street rehabilitations projects.
Street Sweeping
The Street & Bridges Department uses an area concept to ensure as many roads within the city limits receive a fair amount of coverage. Sweeper operators cover approximately 152 standard lane miles of roads within the city. The amount of debris in each area dictates the speed at which the operator is able to complete an area. There is one street sweeper presently in operation. Although low hanging tree limbs and accumulations of silt and debris in gutters are a constant challenge to the program; arterial and collector streets are the highest priority.

What is Storm Water

How It's Made
Storm water is water from precipitation that flows across the ground and pavement when it rains or when snow and ice melt. The water seeps into the ground or drains into what we call storm water sewers. These are the drains you see at the street corners or at low points on the sides of your streets. Collectively, the draining water is called storm water runoff and is a concern to us in commercial and industrial sites as well as your neighborhood because of the pollutants it carries.
Where Does This Water Go?
A common assumption is the water that heads down the storm water flows into a treatment plant. Not so! Unlike wastewater that is treated, storm water does not go through any treatment process. Streets, swales, ravines, and storm drains transport storm water to the nearest stream, creek, lake or other waterway.

Water carries whatever it can with it – trash, leaves, chemical residue. With hundreds of storm drains around town, storm water is a major polluter. Although each storm drain contributes only a small number of pollutants, when added together, pollution concentrations are pretty high.
City of Trinidad Mission
  • To operate a drainage system that provides safe, dependable, surface drainage in each neighborhood that can be maintained easily and at a reasonable cost.
  • To have a proactive planning process that will ensure that new development does not have a negative impact on existing neighborhoods.
  • To improve the environment by improving the quality of storm water runoff by remaining in compliance with Environmental Protection Agency regulations.

Storm Water Pollution

Effects of Water Pollution

Water pollution is a concern for every person on the earth. Water pollution is contamination of water by water pollutants that are allowed to enter water sources without first being treated to remove compounds that are dangerous to people and animals. Water pollution does not just hurt animals and people alike, they also hurt entire communities doing major damage that takes years to cleanup and fix.

Water pollution is a problem that affects everyone. Statistics show that 14,000 people die every day from harmful agents in the water. Contaminated water leads to stomach sickness and many people die from the sickness. Countries that have adequate facilities to filter water still struggle with water pollution. Everyday there are accidents that happen and allow contaminates into the water. Sometimes they are not even known because they happen in remote areas.
Examples of Water Pollution
  • Animal waste that finds its way into the water through a stream or pond.
  • Compounds found in the air are mixed with water from a rain storm.
  • Oil spills
Types of Water Pollution

Point Source Pollution - This is where contaminants enter the water from a single source that can be located.

Non-Pointed Source Pollution - Pollution that does not come from one source, but rather many sources working together. An example of this is from fertilized land. Water runoff collects come of the fertilizer from several different fields and the fertilizer finds its way into the water supply causing polluted water.

Water pollution is a constant battle all around the world. Water treatment facilities work nonstop to provide good, clean water for everyone to enjoy.
