The Importance of Density: Colorado Springs Quality of Life Indicators

Posted in Comprehensive Planning and Codes, Town Planning, Urban Planning and Design with tags , , , on October 13, 2011 by John Olson

The Quality of Life Indicators Report was released last week in Colorado Springs, where I was honored to present the key points from the Built Environment Vision Council. The event was rich with concise presentations including one from the honorable Mayor of Colorado Springs, Steve Bach.

As you may imagine, the report identified many negative components about Colorado Springs in comparison to some of the similar-sized cities in the area. However, the report is not entirely negative. In my presentation, I attempted to focus on some of the brighter points of our community, such as the progress made for bicycle infrastructure in our city and the Downtown form-based code. Where the “red flags,” or problems, were referenced, I made an attempt to offer potential solutions.

The overriding “red flag” in Colorado Springs is a lack of density. Density is a measure of people or dwelling units per square mile or acre. For development purposes, density is typically measured in terms of dwelling units per acre. A lack of density has a multiplier effect over the other quality of life indicators, due to a higher ratio of city resources per person. Resources include roads, infrastructure, and public services (fire, police, schools, transit, etc.).

Colorado Springs had a population of 372,437 people and approximately 185 square miles (118,400 acres) in 2006 according to the US Census. With approximately 2.5 people per dwelling unit in Colorado Springs, this equates to a gross density across the city of 1.25 dwelling units per acre. When we look at our residential neighborhoods alone, Colorado Springs has 31,414 acres of residential, which yields a net residential density of only 4.74 dwelling units per acre.

4.74 dwelling units is a density that is on the low side of even conventional suburban development. The net density is common for detached single-family homes that sit on lots of approximately 100-ft by 90-ft.

In order to alleviate this lack of density, the Pikes Peak Region must explore opportunities for infill. For those who may not be familiar with the term infill, I offered the analogy of the hole in the donut. In this analogy, the outer edges of the donut are the developed and utilized properties, while the hole is the vacant or sometimes underutilized properties. Not only does the city need to fill in the “donut holes”, but they should be filled in with structures that are of a greater density to what was previously developed or even zoned.

A key component to where the city can assist in enabling infill development is in balancing out suburban greenfield development with infill development. The City should revise codes along distressed corridors to provide an expedited process, offer predictable form and allow for the market to dictate the density and parking requirements.

Infill is critical to increasing density in Colorado Springs' distressed neighborhoods. The above Dream City Vision Board was created by John Olson, Jim Houk and Dave Foster.

The City of Colorado Springs fortunately has a precedent in place in the downtown form-based code. The quantitative code in place removes the ambiguity of the qualitative requirements. Qualitative requirements are very open for interpretation and often result in a time-consuming process. Codes similar to the downtown form-based code should be calibrated and created for the areas of dynamism, or areas with great potential for change. These areas are typically failing commercial corridors, originally constructed with single-use buildings with a short life expectancy. For more about Colorado Springs’ Downtown Form-based Code, read Adaptability in Use Changes for Downtown Colorado Springs.

In my presentation, the other major red flag identified was the poor condition of the City’s roads, bridges and lack of transit.  I will discuss this in my next blog post. Please stay tuned.

Infill: A Term with a Variety of Scales

Posted in Sustainability, Town Planning, Urban Planning and Design, Urban Renewal, Urbanism with tags , , on July 21, 2011 by John Olson

Infill is one of those development terms that gets interpreted in a multitude of ways. I like to reference the definition supplied for the National Association of Realtors in the White Paper titled Best Practices to Encourage Infill Development written by Robinson & Cole in December 2002.  The definition supplied is as follows:

…not only the development of vacant parcels of land, but also may include the demolition, reconstruction, or substantial renovation of buildings or underutilized sites that may have been previously developed.”

This is a tremendous definition; however it still is quite vague in the first few words of the statement, “not only the development of vacant parcels of land”.  I believe that further clarification stating that existing infrastructure is in place should be added to the definition.  As it is stated, the term is often abused and includes all vacant parcels regardless of the presence of existing infrastructure.

Last weekend, the 2011 Colorado Springs Sustainability Bicycle Tour focused on a portion of the City where infill is the only manner of new development.  On this tour, we visited one extremely large-scale version of infill and other small modes of infill.  All scales of infill from the tour provide positive changes to the adjacent context.

Gold Hill Mesa is a neo-traditional neighborhood constructed in what was previously the tailing of a historic Gold Mine.  It is located between downtown Colorado Springs and Pikes Peak near Historic Old Colorado City.  Major environmental impacts were mitigated to create a neighborhood that will ultimately be a self-sufficient automobile-independent neighborhood.  Without the major commitment that Mr. Willard and his fellow partners have taken at Gold Hill Mesa, the hill would remain as a blighted eyesore near downtown Colorado Springs.

Smaller, incremental changes of recent infill along the tour included urban infill housing.  Two different areas were brought to the forefront for the participants of the Sustainability Bike Tour.  One of which was a site of two homes that I stumbled upon a few years back after visiting Old Colorado City.  The other was one that I recently stumbled upon in the preparation for the bike tour.  Both examples show the opportunity of modifying blighted, or vacated single-family lots, into multiple lots.  Due to the Euclidian zoning that has been applied to otherwise historic neighborhoods, these opportunities often seem unfeasible.  However, with a little research, it is often found that other homes and uses nearby also do not conform to the zoning code.  By incorporating residences that are now “harmonious” with adjacent uses, additional homes and greater profit margins can now be realized.

The following are the two infill sites included during the Sustainability Bike Tour.  The first set of three homes were purchased from a single lot for $82,000 in 2004 and subdivided into three lots which were constructed and sold for $199,000, $215,000 and $220,000 in 2006 and 2007.

Two new homes were recently constructed near Old Colorado City in Colorado Springs.

The second set of two homes include accessory dwelling units above the garage behind the homes.  They were constructed in 2005 and have a current market value of approximately $235,000 each.

The New Economy 2 of 3

This is the second in a series of three blog posts where I have provided my projections of development as they relate to: Master Planned Communities; Government’s Role in Development; New Urbanism; Transportation; and Homeownership.

So what is the “new economy”? The phrase has become main stream since the light bulb went off for the country when the “old economy” reached its pinnacle and came to a crash landing with the collapse of Wall Street. As the United States pulls itself out from our over-consumptive ways of the early 2000’s, we have struggled to come to grips with what is next for us.

A component of the Denver's Highlands Garden Village is a well-used Co-Housing Community.

 New Urbanism: Over the past few months, I have heard statements about the “death of new urbanism”. I find this statement to be absolutely incorrect, and those who have made this statement did not have an understanding of the breadth of all that is encompassed within new urbanism. The misguided preconception of “new urbanism” may actually be dead. But that misguided preconception of new urbanism (the idea that it was the practice of Colonial architecture located without context of its greater region) is not at all what “new urbanism” is. I like to refer to the Charter of the New Urbanism and its principles, where an important principle that is often glazed over is “Architecture and landscape design should grow from local climate, topography, history, and building practice.”

Several aspects of the new urbanism are very much necessary to our society, as it requires a certain level of self-reliance, or sustainability, in the “new economy”. Infill will be greatly necessary, and ultimately to provide a resilient place, structures and the surrounding built environment will need to be adaptable and loveable, as stated by Architect and Urbanist Steve Mouzon in his book The Original Green.

Transportation: Many believe that there is a trigger point for gas prices in which our society becomes less dependent. Some say that it is $5 per gallon, others say that $4 per gallon, and yet just two days ago I heard $7 is the magic number. Personally, I’m not convinced that there is a trigger number. I believe that it is the prolonged effect that people eventually realize how much that they are spending that becomes the factor. I am a numbers person, so the calculations of how much of my time and income that get devoted to the automobile were the factor that changed my lifestyle and ultimately where I chose to live. Time was actually more of a factor than money for me. For more on my transportation realizations, read CNT Includes Transportation as a Variable for Measuring Affordability.
