SMART GROWTH

by Glenn D. Cooley, P.E.

As an engineer, there is not an easier project than to design a facility on a Avirgin@ site. There are no utilities, environmental problems or existing structures to hinder or impact the design process. However, it usually means we have to provide all new water and sewer piping; sometimes on-site when no public facilities are close by. So sometimes developers and communities end up paying to extend water and sewer to new developments. Is this a good idea when other, serviced, sites may be available?

We=ve all witnessed the Adecay@ of cities, where people move to the suburbs leaving lower, poorer populations to keep up the infrastructure. Now in areas like Buffalo even the inner Aburbs@ are being vacated to another ring of newer suburbs. In the midst of this, sometimes good lots with usable infrastructure become vacant. The theory of Smart Growth attempts to redirect development efforts back toward previously developed sites.

The definition of Smart Growth, in the simplest terms, is ensuring that development and land use patterns are in balance with the need to protect natural resources, enhance communities, invest in urban and suburban center and provide for a better quality of life. Smart Growth principles embrace programs that:

encourage sound planning and greater funding for local planning;

encourage redevelopment of urban areas;

encourage new growth in existing urban, town and village centers;

revitalize brownfield sites;

provide economic incentives to farming and forestry enterprises; and

protect open space for future generations.

Smart Growth provides an opportunity for a grassroots, bottom-up planning process so communities can create and /or protect their identity and sense of place. Above all, Smart Growth means what it says: being smart about balancing economic growth with natural, cultural and community resources.

We can all understand how Smart Growth practices could help Cities, but what about rural Town and Villages? In many such locations Smart Growth practices can reuse old building, isolated vacant lots and make use of existing infrastructure.

By using land efficiently, Smart Growth minimizes infrastructure development and maintenance costs for communities, as well as land development costs for developers. Sensitive use of land ensures water resources, prime agricultural land, habitat, and unique landscapes are conserved for future generations.

 

EARTHQUAKES

By: Jeffrey C. Bahret, P.E.

As Civil Engineers, we often are asked about the phenomenon of earthquakes. Here in Western New York and North Western Pennsylvania, the subject of earthquakes seem to rise to the forefront in regional conversation every two years or so. This article will attempt to answer some of the most commonly asked questions on earthquakes for our area:

Do Earthquakes Occur in Western NY and PA?

One million or more earthquakes are detected by sensitive seismographs on earth every year. By analyzing the records of all earthquakes, we learn that small earthquakes are much more frequent than large ones. However, over 50,000 of these earthquakes are large enough to be felt by people each year. About five (5) of these Afelt earthquakes@ (>2.0 magnitude) occur annually in Western Pennsylvania and New York State. Most of these small earth tremors (<3.9 magnitude) would need to be pointed out to an individual as a earthquake occurrence. Most of the time, people think it=s a large truck causing the sound and vibration.

Over the past 270 years in which earthquake records have been collected and maintained, more than 400 earthquakes for which location could be determined occurred in our part of the country. In this period, which geologically speaking is very short, the largest earthquake in our area was a Richter Scale magnitude of about 6. This occurrence in 1944 was strong enough to damage even well-constructed buildings. It knocked down chimneys and walls and overturned heavy furniture. Even though there was significant damage, this earthquake lacked the power to be classified a Amajor@ earthquake which requires a Richter magnitude of seven (7) or more.

What are Earthquake Magnitude and Intensity?

The severity of an earthquake can be expressed in terms of both magnitude and intensity. However, the two terms are quite different, and they are often confused.

AMagnitude@ is related to the amount of seismic energy released at the epicenter of the earthquake. It is based on the amplitude of the earthquake waves recorded on instruments which have a common calibration. The most commonly used magnitude scale is the Richter Scale. On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; as an estimate of energy, each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value. Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range.

AIntensity@ is based on the observed effects of ground shaking on people, buildings, and natural features. It varies from place to place within the disturbed region depending on the location of the observer with respect to the earthquake epicenter. Although there are numerous intensity scales in existence, the one currently used in the United States is the Modified Mercalli Intensity Scale. This scale, composed of 12 increasing levels of intensity that range from imperceptible shaking (I), to catastrophic AH-Bomb@ destruction (XII), is always designated by Roman Numerals. It does not have a mathematical basis; instead it is an arbitrary ranking based on observed effects.

 

WINDOW REPLACEMENT

By: Al Vanderpoel, P.E.

With the cold days of winter upon us, saving money on your heat bills is a common topic of building owners. And equally as important as cutting the heat bills is insuring that your workplace is comfortable, without cold drafts from windows.

The most likely place for heat loss to occur in your building is through the roof, which often can be easily corrected with the addition of insulation in the ceiling area. But the second most common place for heat loss is through your windows, and occasionally a poor fitting window can also cause cold drafts, which make hot and cold spots in your building. These cold spots without question are increasing your heat bills, but both the cold and hot area are also making the working or living environment uncomfortable. And this is equally true on the hot summer days, when the air conditioning is finding the reverse situation, but with the result being the same hot and cold problem.

The problem with window heat loss might be corrected with maintenance by caulking. However, the more common problem is probably due to the simple fact that most older windows are simply not very efficient when it comes to heat loss. You might consider two approaches to solve this problem. The first is the installation, or replacement, of a top quality storm window. This is a relatively inexpensive item, and can be quickly done with almost no disruption to your building setting. The second option is the replacement of windows in your building. The removal and new installation is not as difficult as it would seem, and can be done with a minimum of disruption by doing one room at a time. We recently were involved in a project where a two story office building had the windows replaced in December, and by closing one room at a time, the disruption was controlled. We can assist you with a storm window or complete window replacement project. You might be surprised at how low the cost of these projects actually are. And we believe that you will be pleasantly surprised at the heat savings, or the new comfort level that you will see after the installation of new windows.

 

SPRING MARSH CONSOLIDATED WETLAND MITIGATION PROJECT

By: Donald Owens, Earth Dimensions, Inc.

Earth Dimensions, Inc. (EDI) is a soil and environmental consulting group located in Elma, New York. Since the wetlands division was founded in 1989 EDI has continued to provide wetland delineation, wetland mitigation design , and state and federal wetlands regulatory permitting services to a broad range of clientele throughout the Western New York region and the Northeastern United States.

Over the years, EDI has heeded its clients expressed need for mitigation options that would reduce the costly time delays associated with finding a suitable mitigation site and limit their involvement in the mitigation process to a one time payment. In response to this need, in 1995 EDI began studying the process of wetland mitigation banking with the intention of establishing a mitigation bank in the Western New York region. In early 1998 EDI set forth the framework for the planning and permitting of Aconsolidated wetland mitigation@ in Western New York. In mid 1998 EDI founded Emerging Wetlands, LLC, a AConsolidated Wetland Mitigation Provider@, to administer future consolidated wetland mitigation projects.

Generally, consolidated wetland mitigation addresses the same need, and provides the same convenience as mitigation banking, but without many of the burdensome administrative and regulatory aspects of mitigation banking. Consolidated wetland mitigation offers the regulated, preplanned, agency approved, wetland mitigation options that expedite the permitting review and approval process and reduces client involvement to a contract and a one time mitigation payment.

The Spring Marsh Consolidated Wetland Mitigation Project (Spring Marsh Project) located in the Town of Newstead in Erie County, is Emerging Wetlands= pilot project for private sector consolidated wetland mitigation in western New York. The Spring Marsh project offers mitigation options including wetlands creation, enhancement, and preservation to satisfy regulatory mitigation requirements.

Emerging Wetlands, LLC is also currently in the process of establishing a consolidated wetland mitigation project in the Town of Chili in Monroe County. This project will provide similar wetland mitigation opportunities in the Rochester area.
