Types of Curb Extensions

Curb extensions physically and visually narrow your city’s roadways. This way, they create shorter and after crossings for pedestrians and increase the street space for signage, furniture, and plants.

There are different types of curb extensions which will be included in your city’s design drawings by civil engineering New Orleans-based firms such as ILSI Engineering. These are implemented in your residential streets, neighborhoods, and downtown. Here are these categories of curb extensions.

Gateways

These curb extensions are typically implemented at the mouth of your intersections. On residential and low-speed streets, gateways are designed to mark the point of transition to low-speed. A gateway is typically 1-2 ft narrower compared to your parking lanes. Stormwater management elements including rain gardens or bioswales are included in gateways for reduction of your street’s impervious surface and absorption of rainwater.

Pinchpoints/Chokers

These are installed at mid-blocks to add public space and slow down traffic. You can add bicycle racks in some areas of the chokers or plant street trees to enhance its aesthetic value. Before planting trees or any other street plants however you should consult your civil engineer and ensure the roots will not interfere with any underground infrastructure.

Chicanes

These are used on low volume downtown or residential streets to produce a chicane effect which considerably slows traffic. They also increase the public space you have on your corridors. Chicanes might warrant additional signage and striping to indicate their presence to drivers.

The right choice from the above curb extensions is pegged on several factors in your city. These include your drains, the city’s topography and outline of other infrastructure elements. With a competent civil engineer, you are guaranteed of getting the ideal curb extensions to enhance your public space and make your city safer for pedestrians.

Dangers of Coastal Erosion: Why We Need to Protect the Coast

by Admin - on Dec 29th 2017 - Comments Off on Dangers of Coastal Erosion: Why We Need to Protect the Coast

Gold Coast, Queensland, AustraliaGlobal warming causes ice caps to melt, and melt sooner. This phenomenon, in turn, raises the sea level, causing beaches to shrink and coastlines to erode. The threat of rising water and coastal erosion is real. While you may not feel the full effect, it is happening, and environmentalists are taking steps to protect the coast.

Repercussions of Coastal Erosion

Engineering professionals from ilsiengineering.com have conducted studies to understand the hydrodynamics involved in coastal erosion. They found that the phenomenon has different effects on coastlines throughout the country. The impact on undeveloped areas, it appears, would not be as big a problem as the result of densely populated areas like coastal cities. The serious repercussions to the latter include:

  • Flooding – With coastal erosion, flooding may become more frequent and dangerous. There are less blockage and water can quickly fill up the streets and cause flood damage.
  • Loss of Land – The coastal land and beach will continually be pushed back by erosion. When this happens, water can weaken the developed areas and make them unusable.
  • Economic Loss – From an economic standpoint, the absence of beaches will lessen the tourists visiting coastal cities for a swim and sunbathing.

What Can You Do to Fix It?

Geography AS Notes suggests that many projects have been completed or are currently underway that can stall coastal erosion. There are two types of techniques experts use, depending on the location of the coastline and the strength of the waves.

The first is called hard engineering technique. It uses solid materials and non-living things to keep waves from crashing to the shore. It includes seawalls, breakwaters, and tidal barriers.

The second technique is the soft engineering technique, which involves the land within and surrounding the coast. The methods include adding sand and shingle to the shore or creating marshlands to break up the waves and reduce their speed.

The environmental protection industry continues to find ways to protect the coast from unnecessary erosion. With new civil engineers entering the industry every year, more innovative ideas for preserving the beach are added.
