We looked at about 20 neighborhoods in the Houston area. So, I can tell you which areas are good and...uh...not so good.
I can tell you Imperial Oaks is VERY nice. It is a large masterplanned community with several neighborhoods within the community. Each neighborhood has it's own appeal. I know several people that live there, and there is not any type of smells at all

It is actually very clean and well manicured. I don't even remember seeing any water treatments around there, and I have been all over the neighborhood. I guess if I missed it, then that tells you how insignificant it must be. Imperial oaks is five miles from the woodlands mall, market street, the pavillion (for concerts), and the trails in the woodlands. You get all the conveniences of the woodlands, but a much nicer house for the money. It is closer to the entertainment area of the woodlands than a lot of neighborhoods actually in the woodlands! There are side walks through out. Imperial Oaks is on the border of the woodlands and Spring, but with great Conroe ISD schools. There are also waterfalls and trees throughout, plus swimming pools. There is a grocery store right outside the neighborhood if I am not mistaking.
If that is the area and price range you are looking at, other nice neighborhoods include:
Spring Trails- a new neighborhood with a pool and trails. Close access to the Hardy Toll road. Very pretty neighborhood. Good schools. I have friends that live here also, and they love it. A little farther from the woodlands, but still within 10 miles. Another master planned community. Clean and manicured.
Legends Estates- Huge Houses with big lot sizes. No side walks though. This is good for people who want small mansions with a slight rural atmosphere due to the large lots and trees. There are ponds in the neighborhood. The price for the house is higher than Imperial oaks or spring trails. Great schools. About 6 miles from the woodlands, but to buy a house this nice in the woodlands would be much more expensive. More house for the money in Legends estates. This is in Spring, but has Conroe schools. Friendly people.
Legends Ranch- Community pools, new houses, close access to I-45 and the Hardy Toll. Good schools. It is a master planned community. Close access to the woodlands facilities as well, but is in Spring. Also, close to the grocery store. Has some trees, but not as many as some of the other neighborhoods mentioned. It is a gated community!
The Woodlands- Lots of trees! A large master planned community. There are restaurants and business's hidden in the trees of this neighborhood. It is so large there are several neighborhoods within the woodlands. The neighborhoods range in price greatly, and some houses are in the millions. There are swimming pools and great schools. Instead of knocking down nature to build homes, they built the homes within nature. As mentioned above, there is a mall, restaurants, and market street within the woodlands. How far you are from this entertainment depends on which neighborhood in the woodlands you reside. There are miles and miles of trails that connect all the neighborhoods. I don't know anyone who does not lilke living in the woodlands.
Just in case you wanted to ask, no there are no smells from any treatment plants in any of the other neighborhoods either.
I think all the neighborhoods I discussed have little parks and recreational areas in them.
Hope that helps.
