It's My Park Day 2008 - Registration is open

It’s My Park Day will be April 12th, 2008. Allandale was one of the first neighborhoods to participate in It’s My Park Day, and the tradition continues this year.

We need volunteers to act as site contacts on the day of the event. The site contact is the central location for the volunteers at each clean up, they sign in volunteers, hand out t-shirts, and distribute snacks and water. They do need to be at least 18 years old, and available on April 12th from 9:00-11:30 am.  They do not need to trim brush, pick up trash etc.

The site contact is really an ambassador for Allandale, it is a great way to meet neighbors.

Please help me in encouraging participation.  These events build awareness of our parks and their value to our community

Volunteers can sign up online: http://www.austinparks.org/itsmypark.html

City of Austin updates FAQ

Stephanie Lott, of COA Watershed Protection, provided an update to the information we have on the detention pond project.  (For complete details, see the previous posts.)

"Below is some information about the purpose of the project, graffiti and the recreational aspects of the site that you requested. We’ve seen a number of specific ideas and comments both on these issues and others that have the potential for enhancing the project. They need further research, and we are working with our engineers to see if any of them can be incorporated into the project to the extent that our budget allows and without conflicting with the flood control purpose of the project.

"Reason for the Great Northern Detention Pond Project
"With this project, we are bringing the site into compliance with the State of Texas dam safety standards. Most of the improvements are intended to protect those living around the dam and downstream of it, as far as White Rock Drive, from the potential failure of the dam in the probable maximum flood. The probable maximum flood is four times larger than the Memorial Day Flood. While unlikely, such a flood is possible. There have been three in or near Central Texas in the past century. The failure of the dam in this type of storm would be a disaster, causing sudden and severe flooding in many homes in the Allandale neighborhood. This project will ensure the integrity of the dam structure during such a storm.

"The improvements, including the concrete wall and spillway, will also help prevent damage to the dam during lesser, but still very large storms. Any time a dam is overtopped, meaning there is more water coming in than it can hold, there is the potential for erosion and damage to the structure of the dam. This dam is currently in good condition, but it will overtop in a severe storm, one that has between a 4 and 10 percent chance of occurring in any given year. The proposed wall will direct the overflow into the spillway. The concrete spillway will protect the embankment from damage.

"Graffiti
"We realize there are concerns about graffiti and were already planning to use an “anti-graffiti” coating on the concrete. We are currently gathering more information about the effectiveness of this product, which we will relay to the neighborhood as soon as possible. You’ve indicated that some of the neighbors have suggested using plants as a screen for the wall to help prevent graffiti. Unfortunately, this is not possible since the plants would have the potential to damage the structure of the dam.

"Preservation of the Recreational Aspects of the Area
"After the project is complete, the neighbors are welcome to use the area as they are currently using it.

  • It will remain a leash-free area.
  • The existing sidewalks will remain, and a new one will be added.
  • We will have to remove the current bench area, since it’s in a problematic location at the top of the spillway. However, we are willing to put in a replacement bench area. Several people at the meeting on Monday, February 4, 2008, mentioned that they would prefer several smaller benches than one large bench area, and we are exploring this option.

"We are not planning to add amenities that are not already there, although we are looking into whether there is anything that we can do to improve parking on the east side of Great Northern. "

Please post your votes and comments to the "Vote!" post on this blog.  I will be providing ALL feedback to the city next week.

The deadline for comments is February 12th.  Do not delay in sending your concerns to me, or posting them to the blog.  It is imperative that the neighborhood submit their issue by this date for any amendments to be considered!

What is a spillway?

From Stephanie Lott, City of Austin Watershed Protection:

"My understanding is that the spillway is where we want the water to flow if it gets high enough to overtop the dam.

   
"The channel or passageway around or over a dam through which excess water is released or "spilled" past the dam without going through the turbines. A spillway is a safety valve for a dam and, as such, must be capable of discharging major floods without damaging the dam, while maintaining the reservoir level below some predetermined maximum level."  ( http://www.streamnet.org/pub-ed/ff/Glossary/glossarydam.html)

Or

“A structure over or through which excess or flood flows are discharged. If the flow is controlled by gates, it is a controlled spillway, if the elevation of the spillway crest is the only control, it is an uncontrolled spillway.” ( http://www.srh.noaa.gov/wgrfc/resources/glossary/s.html)"

Far West / Great Northern Detention Pond Project

Just back from the meeting regarding the Far West/Great Northern
detention pond project.

Thank you to all the neighbors that attended the information session.

FAQ about the project is here:
http://www.allandalereporter.org/gardening/

If your concern is not yet addressed in the FAQ, drop me an note and
I will get it added.

In essence, this project is to preserve the function of the detention
pond and to bring it up to current standards. This is part of a city
wide initiative. Due to the close proximity, and density, of homes
the Great Northern Detention pond will be among the first projects of
this initiative.

City of Austin info:
http://www.ci.austin.tx.us/watershed/flood_pond_great_northern.htm

As soon as visuals from the presentation are available, I will post
them online for review.

If you have other questions, or items you would like to see added,
please contact me offlist, and I will raise the concern with the city.

Austin Energy Speaker to Address Tree Trimming

Michele McAfee from Austin Energy will be at the February 28th ANA EC meeting to discuss the City of Austin’s often controversial tree trimming program.

AE must prune for safety (lines contacting trees can be hot) and reliability. AE is on a 4-5 year schedule for tree trimming around their lines.

The current current trimming is taking place in the southeast corner of Allandale. (Map of trimming here: Download nl11.pdf)

The guidelines are that trees be trimmed at least 6-13 feet from the top-most high-voltage lines (those attached to the top of the pole) and 4-9 feet from the lower low-voltage lines. These are guidelines - many times cuts have to be made farther back on a branch in order to ensure that proper pruning practices are followed. Some trees may need to be removed entirely as there is no way to prune them properly and have the tree survive or be aesthetically pleasing. AE has a program of free trees as replacements for many of the problem trees that grow near the lines.

Austin Energy first alerted the ANA in August, and followed up with flyers at each impacted address, so that the neighborhood could b e alerted in advance.

During this process, each property owner may request the following actions from Austin Energy and its Contract personnel.

  • You may request an on-site meeting with a Contractor representative to review the proposed tree work
  • You may request an on-site meeting with an Austin Energy employee to discuss the proposed tree work
  • You may request to have a third party present during the meetings
  • You may request modifications to the proposed tree work
  • You may request to not have trees removed on your property
  • You may request to be present when the tree work is performed
  • You will receive a written work plan (VWP) documenting the final plan for your property
  • You may request pricing on potential electric system modification to minimize or reduce tree work

Austin Energy is available to answer any questions or concerns about the proposed tree work and also any possible tree replacements for individual properties.

If you or any of your neighbors have any questions or concerns, and cannot attend the February 28th presentation, please contact Michele McAfee at 322-6932 or contact Ray Henning at 322-6930.

Great Northern Detention Pond FAQ

Watershed protection will be making improvements to the Far West Dam.  The project will bring the detention pond into compliance with state criteria so that the dam continues to provide protection from flooding

An information session will take place on Monday, February 4th, 7PM the Northwest recreation center. More information on the project available here

In anticipation of the meeting, the team at watershed protection have provided answers to some top questions neighbors have presented:

Great Northern Detention Pond Frequently Asked Questions (FAQ)

Will the project impact the bike crossing along Great Northern? There may be temporary impact to the bike lanes during daytime construction activities, and we anticipate that there may be some temporary lane closures on Great Northern Blvd. Most of the sidewalk around the pond will be closed during construction, but pedestrians and bikers will be able to cross the pedestrian bridge over MoPac and reach Great Northern Boulevard throughout the project.

Will the project include any water quality improvement to allow our dogs to swim in the water? No, the purpose of the water quality pond is to remove chemicals and heavy metals from storm water runoff before it is released into the creek. This helps improve the water quality of the creek, but also means the pond itself is not safe for swimming.

Parking at the area is a problem. The east side of Great Northern is very muddy with a dilapidated bollard and wire railing, making it a hard place to park. This forces people to park on the west side which is not only illegal, but also dangerous since they must dart across Great Northern. We are not able to build a parking lot at the site, but are looking at options to help control the mud on the east side of the street. At this time, we cannot promise a solution, but we are checking whether there is anything that we can do. If the construction contractor needs to remove the bollards and chain for staging their equipment, then we will replace them.

Yellow-crowned night herons and green herons have been observed in the pond. Will the project impact them? An environmental assessment was performed, and the biologist did not observe any heron nests on the site. Since the herons are not nesting here, our biologist believes that any impact on them would be temporary during construction. In addition, we will not do any tree removal during bird nesting season to limit the impact on any other birds that may be nesting at the site.

Can the spillway stamp be made so it doesn’t look like the sidewalk? Yes.

Isn’t the site grandfathered as a ‘dog park’? Part of the site is designated in City Code as a leash free area, which means there is no legal requirement for owners to keep their dogs on leashes in the area. We welcome the neighborhood to walk their dogs, bike and hike in the area when the construction is finished. However, it should be noted that the land is not official park land. It is owned and maintained by the Watershed Protection and Development Review Department for the purposes of flood and water quality control, and we are not planning to add any additional park-like amenities. It is not safe for dogs to swim in the ponds when water is present.

If a sign will be part of the project, can it include the purpose of the site and the site name? We’re not anticipating any additional signage, but we will be happy to include the name of the site if that changes.
