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.

  1. Are you aware of any others that have surfaced in the last year in Wisconsin?
    I am working on an ordinance in Town of Eagle Wis.
    Enforcement is an issue with Town….do you find more that are enforced by local authority / police / sheriff. Or, do you find zoning to be the muscle behind the penalty?

    1. tom casey,

      as an annoyed, tired, cranky resident of the town of eagle, is there something I could do? the latest for me is an abutter of an abutter who cut down trees in september and now, another light makes night-lights inside my house unnecessary . . . and sleep, I guess, too

      1. let tom casey know, I sent a note with a card and the resident responded positively by screening, or otherwise, toning down the light.

  2. Hi Tom,

    I am not aware of any new or revised lighting ordinances in Wisconsin during the past year, but through a little searching on the internet, I was able to add links to lighting ordinances for the City of Oconomowoc, the City of Appleton, and the Town of Perry. The Town of Perry is particularly interesting as they received a Recognition of Merit from the International Dark-Sky Association for their dark-sky lighting ordinance, enacted in 2009.

    One way to tell that a lighting ordinance was enacted or updated recently is if it addresses LED lighting.

    I am delighted to hear you are working on an outdoor lighting ordinance for the Town of Eagle, Wisconsin. Please keep me apprised of your progress here or via email at mac.com prefix my last name. When your ordinance is passed, please let me know so I can add it here.

    Enforcement is always a problem—that is why the citizens of the town need to be the eyes and ears of the town board and law enforcement. However, the primary purpose of an outdoor lighting ordinance is to set design standards for outdoor lighting. Going through a plan review process before the outdoor lighting is purchased and installed is far better for all parties than going through the expense (and, often, conflict) of remediation. So, to answer your question, I would say that zoning should be the muscle behind the penalty.

    As you consider an outdoor lighting ordinance, ideally it should address the following key areas of concern

    • Light trespass from commercial, residential, and municipal lighting into and onto residential properties
    • All outdoor lighting should be full-cutoff (minimize near-horizontal light—which causes glare, and eliminate direct uplight)
    • Use the lowest effective illumination level needed for the task
    • Use time controls (on/off and dimming) and occupancy sensors wherever possible to save energy and provide illumination only when it is needed
    • LED lighting should have a correlated color temperature (CCT) of 3000K or less (warm white light with less light at the blue end of the spectrum than typical LEDs)

    Existing lighting that does not comply with the ordinance will have to be grandfathered for a period of time (usually several years), unless it is causing objectionable light trespass into or onto a residential property.

    1. Whom in Milwaukee County is knowledgeable on residential light trespassing? City of Greenfield.
      I just got shot down even with all the documentation and knowledge of codes they said the neighbors where not in violation.

      1. Hi Susan,
        I’m not sure about that. Some research on the city of Greenfield and the county would need to be found. That should be found with a little looking on the city government sites with all the ordinances. Some of the small cities seem to just go with the flow of the county. I found that with Sevastopol, which is where I’m actually in – just across the line from Sturgeon Bay boundary. I’ll poke around a bit and see what I can find on the ordinances and share them here.
        Maybe David Oesper has an idea since he has a lot listed here on his blog.
        Tom

      2. Hi Susan,

        I’m assuming you’ve looked carefully through the City of Greenfield Municipal Code which does address lighting and glare, though enforcement is often a problem—or there are loopholes you could drive a truck through. It might be helpful to talk with an environmental lawyer in Greenfield or elsewhere in the Greater Milwaukee area. Have you talked with your neighbor about this issue? I’d be happy to discuss this issue on the phone with you. Let me know if you want to call me and I’ll email you privately with my phone number and we’ll schedule a time to talk.

        David Oesper

    2. Dave, what would you do if you had curmudgeonly neighbors in a very small community (13 houses and and 2 bars…unincorporated) and were unable to reasonably address the light pollution problem? I have not been able to explore any of the night sky beauty and there is nothing threatening any security if they downsized the lumens or bright blue light that affects my viewing. If I were to ask for even atemporary shut down, my neighbor would increase it to spite. Our representative for the town is part of the group of people who have not been accepting of courtesy behavior. I’ve been here 18 years and I’m not leaving until I choose to, but this is one of many violations of my goals and happiness. The amount of light pollution ha caused great expense to block it in my windows and other annoying and infiltrating situations. I live in the country and the person’s light travels far beyond an acre. If I try to do something about this, I’m certainly going to be punished with more light pollution directed to our property. Got any ideas? Jefferson county. Thank you for your interest.

      1. I feel the same ‘fears’ over neighbors. I’m in a larger city of about 8,000 and the neighbors on my street have reasonable lighting, but the gas station / fast food place at the end of the street and another weird photography business (I never see it open or anyone there) are horribly lit and tops of trees in my backyard are hit by that 1/4 mile away. If they re-aimed the lights downward, it wouldn’t be perfect but would be an improvement.
        I’m doing a light pollution lecture at my club next month and may try sending a reminder to the local media to promote it. I’ve been chatting with people on local FB groups asking for lighting examples, and I’ve got nothing but good responses and thank yous for my efforts.
        I did attend a virtual IDA Dark Skies conference a while back and someone talked about neighbors. He did share this letter which may be helpful for ideas.

      2. Lisa, I know exactly how you feel. I, too, have always lived in constant fear of a new neighbor moving in who would trash my night sky and nighttime environment with their lighting and knowing there may not be anything I can do about it. Even an existing neighbor “upgrading” their lighting could cause big problems. I wish we as citizens benefiting from living in a civilized society talked at least as much about our social responsibility and consideration for others as we do about “my freedom”. For us, having a neighbor’s light shining into our windows all night long is just as bad as someone playing their music or a radio at top volume all night long outdoors, or a barking dog 24/7. Does your town have a noise ordinance? If so, one could also make a case for a lighting ordinance, too.

        My advice would be to do one or all of the following:

        (1) Offer to pay for the changes needed to keep the light(s) from shining on your property. Even though it is grossly unfair that the victim should have to pay the perpetrator not to pollute, I have found that this often lets them know how important this issue is to you and is a good faith effort on your part to solve the problem.

        (2) Is there anyone else in your town who you could enlist as an ally in this cause? Even just one other person (outside your household) would greatly amplify your message, and more than one would be even better. Is there a local organization you could take this issue to who would be receptive to your plight? It really is a quality of life issue.

        (3) Is there a local newspaper or online forum where you can address this issue without referencing the perpetrator(s) specifically?

        If you’d like to discuss this on the phone let me know and I’ll email you privately to arrange a time for you to call me.

        Clear, dark, and starry skies,

        Dave

  3. I am proud to say that I, with the support of the La Crosse Area Astronomical Society, got the town board of the Town of Holland to promulgate their lighting ordinances . They were very supportive. I now live in Tucson Az. where both the city and county have strict lighting ordinances because of the many observatories in the area. Lighting ordinances are all well and good but you have to keep an eye on businesses & etc. to be sure they adhere to them. We had a large solar farm built near my home and I had to get on their case to correct their lighting. Now we are having a very large scale Bayer/Monsanto facility being built just down the road. I communicated with them to let them know someone was watching. They have a lot of lights but they are full cutoff significantly reducing any L.P. Just have to work on the local high school and their awful athletic field lighting. Don’t expect anything from them till they decide to redo the facility.

  4. Hi Phil,

    I commend your efforts on behalf of good lighting in Wisconsin and now Arizona. As I remember IDA founder David Crawford saying more than once, “our job of education is never done”. Full cutoff is the key, but reasonable light levels are important, too, of course. Overlighting is so common, and disturbing on multiple levels.

    Dave

    P.S. Based on your comment above, I updated the map link for Holland to the one by La Crosse and not the one by Appleton. I had the wrong Holland but the right ordinance. Thanks!

  5. Hello!
    I found your page through some research I’ve been doing on Link Media billboards in Door County. We have one that went up last August on the border of Sturgeon Bay and Sevastopol. The thing is beaming light nearly directly into the sky. I moved here from horribly light polluted (cloudy too) Seattle three years ago. The darker skies were a big selling point for deciding to relocate here. I am an amateur astronomer also, and built an observatory in my yard.
    The billboard is about 1/4 mile from my house and located on the property of Culvers and a gas station. Not only has the lighting of the gas station become a textbook example of light trespass, but the billboard beams light directly into the sky for about 2,000 feet or so. My SE sky has become ruined with this “death ray” destroying the view, I already see my view of the Milky Way vanishing.
    I’m also VP of the Door Peninsula Astronomical Society in Sturgeon Bay. The club facilities is 1.9 miles south of this light, and it is affecting the sky to the north of our observatory. We have a 16 inch Ritchey Chretien scope, Paramount ME, Cameras…..etc. We have a first class club for a small city. I’ve put a LOT of time into working on this scope to get it collimated and functional (not quite there yet, but close!), and as we come out of the pandemic we have a lot of plans for public outreach, both in person and online – hopefully working with the schools doing live online imaging, and even letting students steer the scope.
    This is all in jeopardy thanks to the city seemingly ignoring the light ordinances. I’ve been in contact with different officials and they basically said “Link has been adversarial to work with” and basically apologized to me saying nothing could be done….so they let them do this anyway?
    Any ideas, suggestions? I’d love to hear from anyone on this list. Seems we are all in the same situation.

    1. Hi Tom, I feel your pain! It would help if we could see some photographs. What is being advertised on the billboard? Unless it is advertising a business that is open all night long, then you could make the case that the billboard illumination should be turned off after 11 p.m. or midnight. That is done in a lot of places. Also, the lights should be mounted at the top of the billboard and shine down onto the sign. If neither of these can be done, then I’m sure at least the wattage of the lights illuminating the sign could be reduced. Or, if the lights are not efficiently illuminating just the sign, lights with a more restricted beam pattern (and lower wattage) should be installed. If the city or county government can’t or won’t do anything, then see if you can find an environmental lawyer in the area who might do some pro bono work. Find allies (both individuals and organizations). This is a quality of life issue. Write a letter to the editor in a local newspaper and see if you can get them to write a news article about how it is affecting the quality of life for you and others. Include how it affects the ability to see the northern lights from the club observatory. And meteor showers such as the Perseids in August.

      1. Hi Tom, just read through your email to me and thanks for the additional details and photos. Here are the photos:

        Offending billboard in Door County

        From the DPAS club observatory 1.9 miles south

        View from a clear night a few nights ago. Stars seen in sky, but bright glare from the billboard is see directed straight up.

        Light seen from my driveway. The Culver’s location is the left light (and the glare from the light pole), billboard on the right – foggy night shows the pattern well.

        1. Thanks for sharing my photos. I’ve been in contact with the local media and spend an hour with a journalist the other night. It was a clear night, and the big scope was behaving (long story, but it’s an RC if anyone knows the fun of collimating a 16 inch!) so I gave a nice demonstration of how it worked and M13 showed up nicely. We stepped out and saw the light pollution display easily. The article should be posted in the next 10 days so I’ll have to share a link when it comes out. I hope I can make some changes.

          1. Tom, this is an excellent article! Should really help the cause for darker skies in Door County. If Link Outdoor Media comes back and says it is too expensive to install or maintain lights on the top of the billboard shining down, please note that those are old arguments that are no longer are valid. A number of billboard companies now routinely offer top-mounted LED lights that shine down on the sign, and the IDA will definitely be able to put you in touch with some of them. LEDs last for many years, and provided that the electronics that drive them are also certified to last for many years, the billboard illumination system should be a zero maintenance proposition—or close to it. Good luck, and please keep us posted!

  6. Than you David! I’ll keep you updated on progress.
    I’m very pleased with the article and I’ve been posting links to it on a few local FB pages, our club page and other places.
    After I really noticed the problem with the billboard, I my travels around I’ve seen many other Link billboards down Door Peninsula along the highway. I was noticing them the other night has heading north, and they all used similar lighting that just skims the billboard, but probably 75% of the light is directed skyward.
    There is another less dominant company (Lamar) that has billboard also. I need to go see one and night still to verify the lighting, but they seem to have longer light bars (maybe about 4 feet long and appear to be no more than maybe 8 inches tall) and the lighting surface is totally parallel with the sign so they may “care” more. I’ll probably drive down late at night and get some shots of those and see. I’ve also got my drone FAA legal with a strobe, so maybe even try a few shots from above. I did test it out from my driveway recently and flew it over the offending billboard. The glare from the sky was extensive and my drone camera couldn’t even properly expose it since it was always overexposed. The strobe worked nicely, I could easy see it from my yard, but need to fly it from closer to avoid powerlines there. Needless to say, I’m absolutely furious about this.

  7. Just another update on this battle. Looks like we won a small victory. I got an email from the Link manager in Green Bay. He said:
    – They moved the lights closer to the billboard
    – Set a timer to turn off midnight to 5am
    – Dimmed the “driver distractor” LED display on the other side.
    So far, the billboard has been off for about 2 weeks now (since I got the email). I’m hoping they just gave up on lighting it at night. I fear that they just haven’t set up the timer yet, but I’m not saying anything! Maybe they realized that even moving the lights closer to the sign wouldn’t do much and to shut me up, they leave it all off? I can only hope.
    Here’s the article: https://doorcountypulse.com/green-notes-stargazers-celebrate-small-victory-for-dark-sky/

    1. This is a great victory, Tom! Your persistence and professionalism have paid off, and Craig Sterrett’s extremely well-written article in the Peninsula Pulse brought some unwanted negative publicity to Link Outdoor Media, so this demonstrates the importance of local newspapers at a time when so many of them are disappearing. Thanks for sharing!

  8. Another update! The IDA Dark Skies Association liked my work I did and my answers to their application essay questions. I’m a new Dark Skies advocate for NE Wisconsin. I’ve got a few ideas that I’m hoping to push (or at least encourage?) to keep our skies here in Door County dark.
    Just zoom on on Wisconsin and you’ll find me – https://www.darksky.org/our-work/grassroots-advocacy/chapters/find-a-chapter/
    They wrote me up in the local news too. — https://doorcountypulse.com/sturgeon-bay-man-selected-as-international-dark-sky-advocate/

    Tom

  9. I just saw an article about Scott Lind who created this list. He’s working on an IDA dark sky site designate area in Wisconsin.
    https://www.jsonline.com/story/news/2022/06/28/driftless-region-wisconsin-vernon-county-wants-become-international-dark-sky-park-kickapoo-valley/7487767001/?fbclid=IwAR0CY1XVvHg9TCJ_BJE1qCE-ccLyvSgDYL4ya9maZcY1oHkKzQg2g__pSTQ

    Does anyone have his email address? I’d like to contact him about my efforts here in Door County, WI. We are really heading for disaster quickly here with increased development – and losing night sky. 🙁

  10. UPDATE: Sadly the fight is on again. The other night I saw the billboard was back on again. I immediately wrote to Link Media basically saying “WTF?”.
    This summer we upgraded our observatory with a super nice Planewave CDK-400 17 inch for $75k, so we have a lot more at stake now with our skies. When Link shut the thing off a year ago, the said they would have it off from “midnight to 5am”, not very good, but when I saw it off totally I didn’t complain.
    He said he would have the crew reset the timer, but I then told him about our new setup, and with primetime viewing for about 1/2 the year when it’s dark at 5pm, the midnight thing was totally unacceptable. We are really stepping up our outreach and education with the new gear, and nobody wants to stay up until midnight when the beam of light in the north shuts down. I think that guy at Link really hates me!
    I have created a FB page “Keeping the Door Dark”. Check it out here, and if anyone here is in Wisconsin and cares about our dark skies in Door County, please ‘like’.
    https://www.facebook.com/profile.php?id=100081509112024

    1. Thanks for letting us know, Tom, and I liked your Facebook page. Your new Planewave CDK-400 17 inch (Wow!) is certainly a good argument for them to keep the billboard floodlight off “for the public good”.

      1. David,
        I did check the billboard last night at 1:15 and it was off. I’ll check it again over the next nights and hopefully verify that it’s on the “timer” like it was before where it was dark all the time. If it’s off at midnight, I’m going to raise hell with Link media. 5pm is not going to work.
        Yes! The Planewave scope is amazing. We are super happy with it, and all images come out amazing with it. It doesn’t even need autoguiding since the guiding is only a fraction of an arc-second.
        I do think we are the small city with the most advanced scope in the state for sure!
        We are working on promoting that too, as backing for the light pollution fight.
        Tom

        1. Just an update on my billboard issue. The stupid thing is on again. Usually after 6pm, and it’s on ALL NIGHT.
          Again, when I emailed the city/county, they did remind me that they are basically powerless to make changes to those since LINK OUTDOOR MEDIA will threaten a lawsuit.
          Basically in Door county from Sturgeon Bay south to Green Bay (where these things grow like weeks) I think it’s up to residents to raise a stink with them. I don’t know any other way to fix this. The thought of giving up and selling my wonderful home observatory in my yard has crossed my mind a few times lately, but I’m not done fighting this yet.

          1. Thanks for the update, Tom, and good luck with your efforts to get that billboard turned off for some/most of the night. I remember a few years back in the Audubon magazine (I think), they called billboards “litter on a stick”. Lighting them up turns the litter into a “dumpster fire”.

            We’re in big trouble if government (by the people, for the people) is paralyzed into inaction because they are afraid of being sued by corporations they are supposed to regulate. For another example of this, look what has happened with vehicle headlights in recent years…

            Seems that grass-roots activism is all we have left (besides voting Democratic). Find allies, as many as possible.

  11. Hi! Does anyone know if there are light trespass ordinances for Milwaukee county or the city of Wauwatosa? My neighbor installed three flood lights that shine directly into our house. It is awful. Any tips appreciated!

    1. Hi Kate, I’m not finding anything specifically addressing residential lighting in the Wauwatosa Municipal Code, but if you look at section 6.72.100 which addresses Used Car Dealers, it states, “Lighting upon such premises shall not be so bright or glaring as to disturb the comfort, quiet or repose of persons in the vicinity.” So there is kind of a precedent.

      The Wauwatosa Municipal Code does potentially address your neighbor’s three floodlights in section 7.18.030 as a public nuisance “in the use and enjoyment of property”.

      I couldn’t find anything in the Milwaukee Code of Ordinances that addresses lighting or light trespass.

      Are the floodlights left on dusk-to-dawn every night? If so, something definitely needs to be done. Have you approached your neighbor about this? There are glare shields available for most floodlights, and in many cases the floodlights can be redirected so that light doesn’t shine directly onto your property.

      If the neighbor isn’t willing to work with you, then the next step would be to contact Tamara Szudy in the Wauwatosa Planning & Zoning Department (tszudy@wauwatosa.net or phone 414-479-3521). Last resort would be to contact a local attorney that specializes in environmental law.

      Good luck – I completely understand how you feel and how this is a violation of your right to peace and enjoyment of your property. I wouldn’t put up with it either. Let us know how it goes.

      1. There has to be an ordinance in violation. I’ve got a similar problem with a gas station 1/4 mile away that blasts my property. I’ve tried for 5 weeks to contact the owner (who is out of state). He did ask for my phone number, gave it to him. I guess he “lost” it when I followed up a week later. Then another few weeks suggested an email conversation.
        Finally reported to the city/county and that prompted a pointy email from him for turning him in. Coming up on 2 months since then, my house is still blasted with light.

  12. Anyone know of any light ordinances in Janesville wi? My parents neighbor has a huge light that shines right in to my parents windows in the room they sleep. My mom has put up multiple blankets over the windows and it still shines in.

    1. Hi Ashley,

      Unfortunately, it does not look like the City of Janesville has a lighting ordinance, only lighting standards for businesses and their impact on nearby residential areas. It also appears that the Rock County Astronomical Society (which might have someone knowledgeable about how to deal with light trespass issues there) may no longer be in existence, but you could try emailing galaxyfinder@yahoo.com who is the listed contact person for that organization. I’d suggest you contact Jennifer Petruzzello, Director of the Janesville Neighborhood & Community Services Department.

  13. Hello,

    We live in the town of Freedom,WI and after a long fight a storage unit was allowed to be built near a residential area. (One parcel was deemed low intensity commercial)
    No lighting plan was ever submitted or and the owner has installed LED lights that are on 45 degree angles directly shining into our house. The sky is lit up for miles around.

    There is a town ordinance that states:

    A lighting plan shall be submitted as part of the site plan.
    (2)
    No exterior lighting, whether freestanding or mounted on a building or structure, shall be reflected or produce unreasonable glare beyond the parcel boundaries. All exterior lighting fixtures, either wall mounted or freestanding shall be identified on the face of the site plan.
    The exterior lighting shall state the dispersion pattern, intensity of light, and cut-off shielding that reflects light downward and in which the light source is not visible from adjacent properties. No undue lighting shall extend beyond the property lines.

    We have contacted the town board and administrator and they are not sure how they can enforce this. Could you please provide guidance as to how we get them to enforce this ordinance?

    1. Thanks for your comment, Leann. What county do you live in? Is it Outagamie, Forest, or Sauk? I would expect that the county attorney might be able to help. Keep us posted.

    2. Leann,
      That city ordinance should cover the situation. It’s not like they were ‘grandfathered’ in with an old rule pre-ordinance. Try seeking out the city council members and send them all an email about this. I had a similar issue with a gas station 1/4 mile away that lit up the side of my house, and my home observatory. Also, there was a billboard on that property also. (Scroll back on this comment thread, David did post my photos). I did win those battles, and the gas station is now well lit – where it needs to be – and that corner of my sky is now dark. Both the astronomer and business wins in this case.
      I did also contact a storage unit also, which promised that they would use proper lights. Did they? Kind 0f , but they have unshielded lights between each unit door. It’s horrible. I did get accused of trespassing by the owner when I took photos of the lights during construction and emailed questions to him about it. A rather pointy reply to in inquiry. This unit is less than a mile from our club observatory. Our club is still showing a bortle 4 sky, but once they update that map, I’m sure we are at bortle 5 now. It’s infuriating and a frustrating battle. I’m actually on the verge of taking down my home observatory and just fighting for the club now. I’m still hoping to maybe get a few more images of Orion before I give it up. — Tom

  14. Hello,

    We live in eastern dane county, in the township of medina. We recently had a trucking company takeover a commercially zoned property across the highway from our rural subdivision.

    A few weeks ago, the nighttime security lighting was fired up – dusk to dawn. Multiple neighbors are impacted by what I can only call stadium intensity lighting. We’ve all contacted the owner of the company and he’s been willing to work with us up to a point. Unfortunately we’re at an impasse and our angle change remedy requests still really didn’t help with sky glow and light trespass.

    We’ve been in contact with our town board and they’ve been open to listening to our concerns. Unfortunately our town doesn’t (yet) have a lighting ordinance in place and our board president has stated there’s really no legal remedy to ‘help’ the owner fix the issue.

    I’m looking for some advice on model ordinances and typical grandfather periods to propose to our town board. This isn’t the first time our town has dealt with light pollution from a business, so there’s precedent to say hey, we need this.

    Any advice would be much appreciated! Thank you

    1. Hi Corey, Have you contacted DarkSky International (formerly IDA) for current advice about the best model lighting ordinance for you to use as a template? Be sure that they understand this is for a rural area and not a city. As for the trucking company, are you able to send me photographs of both daytime and nighttime views of the offending lights? If we see what you’re up against, both Tom and I might be able to give you some helpful advice.

      1. Appreciate the follow up on my inquiry. Regarding your first question, no have not contacted the organization but did find your ordinance links above quite informative! I have a plethora of photos – is there an email you can indicate as to where I forward them?

        1. Definitely try a polite email to the company – sounds like you have done that. I’ve had a couple of wins with emailing offenders. Just write freely at first, sleep on it, edit some more (getting the emotions out), sleep on it again…then when all the cussing and anger is out hit the [send] and let it fly! I’ve had Link Media twice shut down a billboard near my house, but feel I’m on borrowed time with them. I threatened to contact the local media the second time it turned on again, that seemed to help. If it turns on again, I’m not going to squelch my anger anymore though.
          I hope this photo can be seen, this shows the Link Billboards with the light pollution overlay. Easy to see what damage they do.

          Anyway back to your issue. Same thing with the city council in the town. Find the names on the city web page and write and email to all of them (I just blast the same to all members). Tell them not only the night sky damage, but the wasted money on energy, light trespass on your property, even bird migration, pollinators, human health (melatonin production is a big deal with light at night) and other things you can probably find. If there is an astronomy club nearby maybe? Write to them also.
          Just some ideas that I can toss out that have worked (or at least made me an annoyance in my city of 9,000 residents).
          — Tom

          1. Yes, we’ve had good discussions as a neighborhood with those folks on the board and they’re sympathetic to our collective plight. Due to no lighting ordinance or zoning issues with the lighting per se, the board has noted they don’t have an official recourse to assist. Hence the next step being the ordinance inquiry and examples of grace periods.

            I’d like to send you both the pics of the lighting I’ve taken, if either of you can share a contact.

  15. If the town doesn’t have a lighting ordinance, try the county maybe. I know that here in Door County some of the towns just fall under the county ordinances. I know there is a group in Madison that is trying to work on a dark sky movement in that city also. It looks like Medina area would fall under that. Check out their Facebook page here. I’m sure there are some others in there that would probably back you up also.
