In an update to the two posts above, holiday lighting will be able to twinkle and flash. Thanks to the above comment, the section on holiday lighting will be clarified to add this to show that it is allowed for holiday lighting.
The reason that the installation of artificial turf needs ARC approval is that the guidelines specify a minimal standard of artificial turf that needs to be installed. Artificial turf is manufactured in many ways and some of the very cheap artificial turf is made of materials that will not last or look well in this climate. A brief explanation of your plan along with a sample of the turf or the manufacturer’s specification of the grade of turf being utilized is basically what you would put on your ARC application.
The ARC process is straightforward and if you want information, assistance, or just want to know the reasoning for a rule please contact the Community Standards Manager, James Arteaga, at 702-614-5820 or email firstname.lastname@example.org
