    In developing a vacant piece of land, steep slopes are often an issue. And, the more prevalent the steep slopes are on a site, the greater the likelihood that retaining walls will be part of the Approved Site Plan.

  • Hydroplaning is frequently alleged to be a cause of vehicular traffic accidents. This is because many persons, even law enforcement personnel, may not know the technical definition and criteria for hydroplaning.

    Many vehicular accidents happen because drivers are in too much of a hurry or they are distracted by any number of things. They just are not paying close enough attention to their surroundings. Traffic accidents at signalized intersections are common where both drivers claim the other driver is at fault.
