As always, great advice. I'll expand on it only to help understanding.
RFI is like any other radio transmitter connected to an antenna -- make
RF current flow on a piece of wire and it will radiate. The more power
and the better the antenna, the greater the strength of the radiated
RF. The antennas can be anything conductive connected to the source --
power supply conductors, audio cables, video cables, etc. Wires running
down a wooden pole to "ground" power wiring are ANTENNAS, and will
radiate any RF current that they carry, including arcing on the power
system. Coax carrying video and/or internet signals are antennas, and
will radiate RF trash generated by the equipment to which they are
connected. Virtually everything connected to a power source (battery or
AC power system) is a potential noise source, every piece of
electronics, including microprocessors built into products like
refrigerators, washing machines, dryers, etc.

There is no definitive answer to this question. In just a few replies, you
can see that RFI can travel great distances. There are an infinite number
of combinations all of which result in a widely varying range.
There is no way to predict if the new subdivision will raise your noise
floor. It's likely but impossible to predict. The suggestion made to begin
measuring and recording your current noise floor is a good one. As the
subdivision grows you may see your noise floor come up.
Check to see if the electrical utilities planned for the new subdivision
will be overhead or underground. If underground, less noise is likely.
