Speeding in gated community

We have some residents who drive their cars as fast as they can in and out of the entry/exit gates and through the streets of our community. We do not have posted speed limits. We believe that won't stop the few who don't care and will look unsightly to those how do care. The speeders are mainly the teenage sons, daughters and friends of residents.
What is/are the most proper and effective methods to deal with this ?
Thanks for your help.

Maybe they think that they have a flash pass, but it's inevitable here...As much as people hate them, you may have to add some speed bumps right before the entry/exit gates, or add some stop signs at these gates, or at the intersections if they don't already exist. It may time to place at least one sign at the entrance stating that the speed limit is 25MPH throughout the community. Identify who's guest is speeding and send them a C&D letter.
What state are you in? What do the docs say about speed limits? anything? Maybe it's time for a resolution that addressing speeding and/or parking in nec. It' going to be a little difficult to enforce speed limits if it's not posted.. I would think.

We fought the idea for years, consulted with VDOT engineers, and then after one of our residents ran down a pedestrian while driving on the wrong side of the road at about 40MPH in order to cut a corner. The impact knocked our resident pedestrian up in the air, did a 360 mid air, broke his hip, and leg in two places. The next week, the speed bumps and stop signs went in right away, since the Board was now about to be sued possibly as excess. It didn't help that the insured vehicle was carrying mininum statuatory limits on an assigned risk policy. At least for now, it might be time for traffic calming devices like stop signs. You say that you live in a gated community, but I take it that the gates are always open. If there that much traffic that an access gate cannot be left closed until the vehicle comes through? Camera's already installed?

The speed limit sign at the entrance makes sense to me.
The letter is the least that we should do.
We are in Arizona. I'll check our CC&R's for the exact wording.
I agree that enforcing a speed limit that isn't posted would indeed be tough.

Everyone won't be punished if they are going the speed limit that you claim is the problem! The 'appropriate' hump will not affect the vehicles doing the speed limit but will be noticed by the speeders.

Try the simple stuff first.. Speed bumps are expensive to install, expensive to maintain, hated by most (to include the fire dept), and it's unneccesary wear and tear on vehicles. There are also speed "humps" which only affect the speeders. They are wider and have less of a gradient. good luck.

Thanks everyone,
We have no mention in our CC&R's of a speed limit within our gates. So we are going to decide on a speed limit and notify all residents. We will probably post a speed limit sign. And we have isolated a couple of offenders and are going to notify them directly that we have observed them driving too fast.

(Our entry gate is all automatic, no attendant on duty.)

Indeed we will do it in writing. Certified letter to the offenders and mailed letter to all homeowners.

We can start with the letter(s) and stress that if speeding continues to be a problem then the next level of control will be speed humps. We were quoted $1600 to $2000 for each hump. WOW, that might be enough to get peoples attention.

Good point. We do issue fines for other violations.

Just remember that speed bumps slow people down and can save lives, but it can also work in reverse. If you are having a stroke or heart attack where seconds count it will slow down that ambulance and first responder. Or if someone is trying to break into your home it will slow down the police. Of if your house is on fire it will slow down the fire trucks.

I agree with the one poster, start with some smaller things, maybe signage, maybe a letter to the parents, fine the parents if possible. You can always put in speed bumps later.

Within the state of Texas, and specifically within Guadalupe County and the City of Schertz, by code all gated communities are considered to be private property. Therefore, in the event of an abundance of speeders, we cannot ask for law enforcement assistance since our designated speed limit is under 20 MPH throughout the community. Yes, we have a speeding problem, but from my viewpoint 85-90% of the speeders live in the community. Other homeowners seem to think all the speeders are just visitors. When the subdivision was established 13 years ago, a 15MPH sign was posted prior to entry gate and several locations within the subdivision. We are currently going through a lot of issues between homeowners and the city in determining what rules can be enforced. Our CC&R's, as developed by the home developers, are extremely weak and we have found the majority of them cannot be enforced. Our biggest issue is the CC&R's and other HOA documents were not written for a gated community, but a public accessible area.

Ask the police to patrol more often. Send a letter to all the members "due to increased speeding the police will be patrolling regularly and issuing tickets, thank you for slowing down"

Maybe look into buying your own cheap speed camera. While you can issue tickets to known home owners, you wont be able to do much to visitors.

I'm late to the party as usual, but check your state laws. Here in Ohio private communities are permitted to have local law enforcement enforce speed limits so long as the speed limit is at least 25 MPH (the standard for residential areas in Ohio).

When we lived in the condo it was a moot point because it was impossible to get up to 25 MPH before having to make at least one 90 degree turn; the design of the property pretty much kept speeds down.

In our HOA we had a few straightaways where people would really crank it up. We requested the police department to drop off their speed trailer a few times and they did. These are the trailers that say "Your speed XX MPH" They don't take pictures or anything but they do let people know how fast they're going. After a few weeks of this we published the relevant Revised Code section that allows police to ticket in private developments and indicated that we were putting the finishing touches on a patrol agreement. The city was then kind enough to send an auxiliary officer out randomly for a month or so and people got the message pretty quickly.

Eventually it got to the point where we just had to have the trailers come by every few months along with an accompanying reminder the newsletter that the local PD can and does enforce traffic laws on the property.
