Dodgeville Streetlights

Has anyone else noticed how Alliant Energy is gradually replacing our orangish-white-light streetlights with bluish-white-light ones? The orangish-white-light streetlights are high-pressure sodium (HPS) with a correlated color temperature (CCT) of 1900K, whereas the bluish-white-light streetlights that are replacing them are LED with a CCT of 4000K, and, most notably, they are two and a half times as bright.

Even though I have written to both Alliant Energy and the City of Dodgeville, nothing has changed.

My questions, which are still unanswered:

What is the justification for increasing the streetlighting illumination level by two and a half times over what it has been for decades?

Why are we going from 1900K to 4000K (cold white), when 2700K or 3000K (warm white) is readily available and being used in many communities in the U.S. and Canada?

This same transformation is happening in Mineral Point, and probably many other communities in SW Wisconsin as well.

Is anyone else noticing how this is profoundly changing the rural character of our nighttime environment? Is anyone else concerned about this? The increase in glare and light trespass onto neighboring properties from these new LED lights is quite noticeable to me, even though they are nominally full-cutoff. Why? They are too bright, and too blue.

If anyone locally is reading Cosmic Reflections (and sometimes I wonder if anyone is…), and if you have noticed and are alarmed by these streetlighting changes, please contact me on blog or off blog (oesper at mac.com) and let’s meet and discuss a plan of action. Something needs to be done before it is too late and we are stuck with this very negative change to our nighttime environment.

Stevens Point

I visited Stevens Point, Wisconsin for the first time over the Memorial Day weekend and, I have to say, this community of 26,000 is impressive. A great place to stay while you’re there is the Baymont Inn & Suites at 247 Division St. N. It is a short and pleasant walk to the University of Wisconsin – Stevens Point campus, the Schmeeckle Reserve (wow!), and the Green Circle Trail. Michele’s Restaurant is only a few blocks down the street. Great food!

I miss living in a college town. It is energizing to interact on a daily basis with well educated, intellectually curious, and cosmopolitan people who are passionate about their work. I lived in Ames, Iowa—where Iowa State University is located—for nearly 30 years, and I feel more at home in Stevens Point, a smaller community, than I do now in Ames. I think Stevens Point is the nicest community I have visited since leaving Ames in 2005. Definitely would be willing to live there someday. UW-Stevens Point even has a physics & astronomy department, an observatory, and a planetarium. Perhaps I could help out in retirement.

Some towns have a lot going for them even without a college or university—around here, Mineral Point and Spring Green come to mind. Some towns are at somewhat of a disadvantage because they have a name that is not particularly attractive. For example, Dodgeville, where I currently live and work, has a moniker that isn’t all that inviting. But there is no place so nice to live as a college town—for people like me, at least.

My primary civic interests are in gradually developing a well planned network of paved, off-road bike paths, walking trails through natural areas, a center for continuing education, a community astronomical observatory, and a comprehensive and well-enforced outdoor lighting ordinance to restore, preserve, and protect our nighttime environment and view of the night sky. Living in a community like Dodgeville, I don’t get the sense that there is enough interest or political will to make any of these things happen. I can’t do it alone.

Right Turn on Red

It is time to put an end to right-turn-on-red. It unnecessarily puts pedestrians and bicyclists trying to cross at crosswalks in harm’s way. I’m old enough to remember driving when a red light meant stop—and stay stopped—always. I’ve never liked right-turn-on-red. During my 21 years working at the Iowa Department of Transportation, I learned that doing whatever we can to minimize the potential for driver confusion or uncertainty will always improve safety.

Massachusetts was the last state to adopt right-turn-on-red, on January 1, 1980. New York City still bans right-turn-on-red, unless a sign indicates otherwise. That should be the norm, not the exception.

Short of an outright ban, a good approach would be to put up signs at major intersections with crosswalks, as shown below, but I would add “or bicyclists” as bicyclists often must use pedestrian crosswalks when it is not safe to ride in the street.

“No Turn on Red When Pedestrians or Bicyclists Present” would be even better

The most dangerous situation occurs when a pedestrian (or bicyclist) is waiting for the crosswalk signal to turn from “Don’t Walk” to “Walk”, and a driver who will be crossing the pedestrian’s crosswalk is stopped at a red light. The driver is eager to make a right turn on red and can’t really see when your crosswalk signal turns to walk, so they may turn right in front of you at the same time you are (legally) starting to cross the intersection. This is even more dangerous for bicyclists because they move faster into the intersection than a pedestrian does. This situation is illustrated in the diagram below.

A pedestrian or bicyclist at the SE corner of this intersection is in danger crossing the street either west or north.

Here in Dodgeville, Wisconsin, a particularly dangerous location for pedestrians and bicyclists is the south-to-north crosswalk at the SW corner of the intersection of Bequette and US 18, where drivers frequently make right turns from US 18 EB to Bequette SB. Right turns should be prohibited here with a sign that says No Turn on Red When Pedestrians or Bicyclists Present.

The red “X” marks a particularly dangerous location in Dodgeville for pedestrians and bicyclists because right-turn-on-red is allowed here.

Gas Tax and Road Maintenance

State and local roads and city streets have been in a downward spiral of deterioration for the past several years and something needs to be done. You have no doubt noticed this driving, but try riding a bicycle and you will really notice how bad things have gotten.

Here in Dodgeville, Wisconsin, many of the city streets are in such bad shape they are becoming dangerous for bicyclists. And more difficult, too. Ever try riding up one of our many hills on pavement that is badly cracked? No wonder I hardly ever see anyone else biking here.

I think the best way to fund road resurfacing and reconstruction projects is to increase fuel taxes. These taxes should not only fund maintenance of state roads, but local roads and city streets as well.

The current gasoline tax in Wisconsin is 51.3¢ per gallon. This includes the following components:

  • Federal tax: 18.4¢ per gallon
  • State tax: 30.9¢ per gallon
  • Petroleum inspection fee: 2.0¢ per gallon

Let’s increase gas taxes in Wisconsin by a minimum of 8¢ to 10¢ per gallon (more would be better) and use all of that revenue to resurface and reconstruct roads throughout the state. Small communities and rural areas are most in need of assistance.

A Traffic Light at Merrimac

Even though the population of Dodgeville, Wisconsin is only around 4,800 people, there is quite a bit of traffic congestion along Dodgeville’s only real north-south through street: Iowa/Bequette, otherwise known as Wisconsin State Highway 23.

You’d never know it just driving through town, but the south part of WI 23 in Dodgeville is Iowa St. (S. Iowa St. south of Division St. and N. Iowa St. north of Division St.), and the north part of WI 23 is Bequette St., with the dividing line being Spring St., an unholy mess of an intersection that also includes Main St. and Diagonal St. (signed as Ohio St.). This is the perfect candidate for a roundabout if I ever saw one.

Making a left turn onto Iowa St. (which we often have to do) can be nerve-wracking with traffic, pedestrians, and in places poor visibility due to parked cars. A good way to solve this problem (and reduce the likelihood of accidents) would be to have one intersection along Iowa St. that has a traffic light. I think the ideal location for a traffic light would be the intersection of N. Iowa St. and Merrimac St.

Bike Ride to Ridgeway (and back)

Ridgeway, Wisconsin is a special place.  A point right on the central meridian of the Central Time zone and the 43rd parallel (90° W longitude and 43° N latitude) is within the city limits of Ridgeway, and you can almost get there from here.

The point 43° N, 90° W

You can easily bicycle to this location by taking the Military Ridge State Trail into the west side of Ridgeway and turning north onto Ternes Ct.  I wonder if there’s a marker along Ternes Ct. at its closest point to 43° N, 90° W. If not, we need to put one there.

Getting to the point 43° N, 90° W

But wait!  Right where Ternes Ct. intersects Bier St. and becomes a gravel road, there’s a sign that says “Game Farm, No Trespassing”.  Foiled!

You know, we should have regular bike rides from Dodgeville to Ridgeway and back along the Military Ridge State Trail.  Anyone interested?  The distance from the Wisconsin DNR parking lot in Dodgeville to Badger Mart right next to the trail in Ridgeway is 9.2 miles, so it would be an 18.4 mile round trip along pretty flat terrain.  Badger Mart in Ridgeway is a convenient place to stop for a snack and a beverage before heading back to Dodgeville, and they are open from 5:00 a.m. until 9:00 p.m. every day of the week.

Would love to see this trail receive an asphalt surface someday, but the existing screened limestone surface isn’t bad.

Please post a comment here or email me if you’re interested in making this ride with me from Dodgeville to Ridgeway and back!

March for Our Lives

I am so very proud of what hundreds of thousands of Americans of all ages did today, marching in hundreds of anti-gun-violence rallies all across our nation.  I’m especially proud of the students.  We had a huge group of marchers in Mineral Point, Wisconsin (students included), and I was glad I participated.

I do not want to live in a country where everyone is armed to the teeth.  You know, you have to decide what kind of a world you want to live in and then work towards that goal, no matter how difficult.

Paul McCartney at a March for Our Lives event in New York City

I was devastated and angry when John Lennon was shot to death in New York in 1980 outside his apartment building by a very disturbed man (it is almost always a man, isn’t it?).  I mean, who the hell would kill a musician?  I will never get over it On that day (and many times since), I decided “enough is enough”.  Gun ownership should be a privilege that has to be earned, not a right.  And weapons of war do not belong in the hands of private citizens—ever.  If that involves repealing the Second Amendment to the United States Constitution, then so be it.  But “we the people” never get a chance to vote on gun issues, do we?

If gun owners in this country can’t support much stricter and sensible gun laws, then maybe we should peacefully go our separate ways.  Gun lovers can have their country (a dystopia, really), and the rest of us can live somewhere else.  I would support a civil separation, but never a civil war.  (Besides, we know what side has most of the guns.)

“The young do not know enough to be prudent, and therefore they attempt the impossible, and achieve it, generation after generation.”

– Pearl S. Buck (1892-1973)

Dateline 2024: Total Solar Eclipse

In little more than six years, another total solar eclipse across the continental U.S. will pass as close as Southern Illinois and Indiana.  Like our recent eclipse of August 21, 2017, the next total solar eclipse will also take place on a Monday and, remarkably, just a few minutes earlier in the day.  Save the date: April 8, 2024.   Actually, not long to wait.  Think about what you were doing around December 7, 2011.  Can you remember?  No question about it, the next six years will go faster than the previous six did.  Seems that as we age our sense of time changes, and time seems to go faster and faster.

The point of maximum length of totality for the 2017 eclipse was 12 miles NW of the center of Hopkinsville, Kentucky, where totality lasted 2m40s and the path of totality was 71 miles wide.

The point of maximum length of totality for the 2024 eclipse will be near Nazas, Mexico (in the state of Durango), where totality will last 4m28s and the path of totality will be 123 miles wide.  Yes, this will be a longer eclipse!

Remarkably, there is a location in southern Illinois that is on the centerline of both the 2017 and 2024 eclipses!  That location is 37°38’32” N, 89°15’55” W, SW of Carbondale, Illinois, near Cedar Lake and the Midland Hills Country Club.

When did a total solar eclipse last grace Dodgeville, Wisconsin?  Nearly 639 years ago, on May 16, 1379.  The duration of totality was 3m48s.  Perhaps the Oneota people then living in this area witnessed the event.

The next total solar eclipse visible from Dodgeville won’t happen for another 654 years.  There’ll be annular eclipses in 2048, 2213, 2410, 2421, and 2614.  Then, finally, on June 17, 2672, the totally-eclipsed Sun will once again grace the skies of Dodgeville—weather permitting, of course.  The duration of the eclipse at Dodgeville will be 2m47s.  There will be another annular eclipse in 2678, followed by another total eclipse (duration 3m01s) on June 8, 2681.  Then, just two years later there’ll be another total eclipse at Dodgeville: on November 10, 2683 (0m49s).  That’s three total eclipses and one annular eclipse visible at Dodgeville in just 11 years!

LED Residential Streetlight Debut in Dodgeville: Too Bright!

A new bright white LED streetlight made its debut in Dodgeville, Wisconsin on Friday, November 3, 2017, and it isn’t pretty.

The white-light LED streetlight is located at the NE corner of W. Washington St. & N. Johnson St. in Dodgeville.  The illumination level on the ground peaks at 3.15 fc.  An existing orange-light high pressure sodium streetlight at the SW corner of W. Division St. & N. Virginia Terrace peaks at 1.23 fc, which is typical.

Even though the reduction of uplight and near-horizontal light (i.e. “glare”) from this luminaire is a welcome improvement, an illumination level 2.6 times as bright as before is neither welcome nor justified.  Furthermore, lower illumination levels may be acceptable when using white-light LED luminaires in comparison with high pressure sodium (Glamox n.d.).  More research is needed on the effect of spectral composition on both brightness perception and, more importantly, visual acuity at various illuminance levels.

I do not have an instrument to measure the correlated color temperature (CCT) of this luminaire, but visually it looks to me to be around 4000 K, which is too blue.  I will check with the City of Dodgeville and report back here.  The International Dark-Sky Assocation (IDA n.d.) and the American Medical Assocation (AMA 2016) recommend using “warm white” LEDs with a CCT no higher than 3000 K, with 2700 K preferred.

The Wisconsin State Law Library maintains a comprehensive list of Wisconsin Ordinances and Codes.  This will be a good resource for us to find additional outdoor lighting codes and ordinances to be added to this list, as well as to check your local government’s codes and ordinances in general.

It is interesting to note that nearly two-thirds of these ordinances are for suburban communities in very light-polluted metro areas.  Another four ordinances are no doubt in place to help protect the Yerkes Observatory (Williams Bay, Geneva, Fontana-on-Geneva Lake, and Delavan).  Where are the rural ordinances and dark sky preserves?  Since there are very few remaining locations in Wisconsin where the night sky is truly dark, shouldn’t we be aggressively protecting those areas?  Wouldn’t it be easier to save a pristine area than to restore an almost hopelessly polluted one? Another interesting point is that upscale suburban communities are much more likely to have a lighting ordinance than more affordable communities.  Some subdivisions even exclude streetlights, but these are almost never places where most of us can afford to live.
