  1. Q: What jurisdiction or authority is in charge of RM 620 traffic from RR 2222 to Anderson Mill Rd?  
    A: in addition to law enforcement officials (city, county, Highway Patrol, etc), the actual physical roadway of RM 620 is controlled by Texas Dept of Transportation (TxDOT) while the signal light timing inside the Austin city limits is controlled by the City of Austin Transportation Dept.
  2. Q: Why is traffic congestion on RM 620 so bad, particularly at peak hours?  
    A: The current actual daily average traffic volume on RM 620 is approximately double the daily average design traffic capacity of RM 620 from RR 2222 to Anderson Mill Rd.  In addition, the intersections of 620/2222 as well as 620/Anderson Mill Rd are currently rated “F” level of service (“F” being the worst rating possible on a scale of “A – F”) which basically means that the intersection is severely overloaded at peak hours with lengthy relative wait times at a signal light.
  3. Q: Are there any large development projects planned on RM 620 that may negatively impact traffic?  
    A: Yes. A large 27 acre shopping and office center is planned at 7710 N RM 620 (between CVS at 2222 and Home Depot at Vista Parke Dr).  In addition, a 5-story, 95 unit Hyatt Place Hotel has just broken ground and has started site preparation work. The hotel address is 7300 N RM 620 and is located right next to the CVS at the 2222/620 intersection.
  4. Q: How and when will the severe traffic congestion on RM 620 be significantly improved?   
    A: TxDOT has recently authorized two traffic studies to work on both short-term improvements as well as the bigger and much more costly long-term improvements (8-15 years) that may entail either a widened existing roadway (widen from 4 lanes to 6 lanes) and/or an elevated roadway that would be similar to I-35 at downtown Austin.  New development in our area continues so significant traffic congestion will gradually get worse before any new road improvements can offer relief.  On a positive note, new “smart signal light technology” will be employed in the not too distant future throughout Austin.  Existing timer driven signal lights will be replaced with real time traffic monitoring lights that actually take into account existing traffic conditions and change light timing appropriately to optimize traffic flow.
  5. Q: What can CC residents do to help improve the significant traffic congestion on RM 620?  
    A: Participate in a greater community effort composed of residents of CC and many other neighborhoods along or near the RM 620 corridor that actively advocate for and solicit traffic improvement related project funding from local city and county entities as well as CAMPO (Capital Area Metropolitan Planning Organization). Note: CAMPO actually approves and funds capital street and bridge projects in our six county area of Texas.  See additional information on the 620 TxDOT link.  See Canyon Creek contacts below for more information on specifics.
  6. Q: What is the speed limit within the Canyon Creek subdivision?  
    A: 35 mph except where posted with a reduced speed limit such as around our school, parks and crosswalks.
  7. Q: How can we encourage drivers to observe the posted speed limits on Boulder Lane and other streets in CC?   
    A: The CC HOA board has authorized the purchase of two (2) radar speed signs to be installed in mid-summer 2018 at proposed locations on both the north and south portions of Boulder Lane.  The north Boulder location will be very close to the driveway entrance for the pool/tennis courts.  The south Boulder location will be just across the street from the Savannah Ridge intersection.  Also, we encourage residents to report observed unsafe driving to 911 for a response from Austin police if the event just occurred (within 5 minutes) and some details of the vehicle can be provided such as vehicle make, model, color, license plate #, etc.  Speed humps will not be an allowed traffic calming option on Boulder according to current Austin Transportation Dept. regulations.
  8. Q: What is the purpose of the planned radar speed signs that are scheduled to be installed in mid-summer of 2018 in CC?  
    A: We are confident that these two permanently installed radar speed signs will result in traffic calming and generally fewer incidences of speeding which will promote traffic safety.  The intent of these units is to make the driver more aware of their speed and surroundings and to modify behavior on both a short term and a long term basis.  Data (date, time, speed) from these units will be analyzed by the HOA board and city transportation engineers to help refine and identify further potential traffic safety related actions that can be taken to improve safety.
  9. Q: Will a driver or vehicle owner receive a speeding ticket if a radar speed sign detects speeding?  
    A: No. These units have no cameras.
  10. Q: How can I get more involved in traffic and safety issues in the CC neighborhood and surrounding areas?  
    A:  Contact the CC Traffic/Safety Action Committee at
