Q: With regard to the Suburban Residential Design Challenge, is
flexibility allowed with the final cross section and alignment of the
east west drainage channel within the project boundaries, while
holding the connection points on the eastern and western boundaries
fixed?
A: We can be flexible, and would like to see some meander to it.
However, doing so may significantly affect the lot yield or
marketability of the commercial property. These are important
considerations. But we are very much open to new ideas, so the anser
is yes, competitors have the latitude to explore, keeping mind our
overall goals.

Q: With regard to the Submittal:
1) Is the format really meant to be PDF rather than PPT?
2) If not, do you mean to say that everything, including all drawings
and the financial and hydrologic justifications ann must be on a 30
page PPT?
3) Do we need to include the 7 minute Finals presentation in our
submittal?
A:
1) The electronic submittal format is to be in PowerPoint (PPT)
format.
2) Everything must be contained in the 30 slide submittal, but please
be aware that a multiple page document (such as your justificaions may
be) can easily be incorporated into a single PPT slide. A Submittal
Guide PowerPoint has been added to the Submission section of the
Competition Program at the www.houstonlwsforum.org website.
3) The finals 'lightning' presentation should not be submitted at this
stage. It is only required of the Finalists, who will be announced on
January 11th. It will not be necessary for Finalists to submit their 7
minute presentations for review, however Finalists may be asked to
provide them a day in advance of the Finals Event to facilitate
preparations for a technically sucessful finals program.

Q: I noticed that the competition program indicates that a team can
add individuals that were not included on the original Registration
Form, by simply submitting a new Registration Form with the entry
submittal on December 14th. May we use this same approach under the
following somewhat similar circumstances?
Our architecture firm wants to participate, but we are not sure which
individual(s) will actually be assigned to the project. Can we simply
register with our firm name and then supply the individual names and
signatures on a Registration Form that accompanies our entry Submittal
on December 14th?
A: Yes.

Concerning the Urban Redevelopment design challenge:
Q: The drainage area for the Urban Redevelopment project seems to be
bounded by Walker, Dowling, Bell, & Hutchins according to the
Duplantis report. This would suggest that the entire block (all 12)
would drain to Bastrop. This would also suggest that the cross streets
between Hutchins and Dowling would drain to Bastrop. Contrary to this,
the map of the project site area from the website suggests that only
half the blocks (all 12) would drain to Bastrop. The other half of
each block would drain to either Hutchins or Dowling. This seems to
make more sense to us. We would be happy to create our own existing
conditions hydrograph etc. for this scenario if acceptable.
A: Our intent was, as you suggest, to incorporate drainage for “…only
half the blocks (all 12) would drain to Bastrop. The other half of
each block would drain to either Hutchins or Dowling.” However, the
calculations previously posted on the website reflected,as you
suggested, "entire block (all 12) would drain to Bastrop." Thank you
for pointing this out. We have just posted the revised document to the
competition website. We apologize to all for the error.
I sincerely appreciate your offer to create your own calculations, but
from the perspective of facilitating the judging of the design
solutions, we really must insist that all competitors to use the ones
we’ve provided.
Q: The instructions from the website state that we are to use the
storm sewer at the northeast area of the project as our outfall (near
Bastrop and Walker). However, according to the City of Houston
Comprehensive Drainage Plan, our outfall should be the 36" storm sewer
at Bastrop and Dallas. We would like to use this as our outfall. It
really doesn't help or hurt us in our design or our case for LID, but
we would like for the effort we put into the design to be useful for
the actual project as you can imagine. If this were a real project we
would use the 36" storm sewer. We don't however want to be penalized
for not following instructions.
A: We realize that there are other options with regard to outfall. In
fact, as you’ve seen, we posted a number of background documents, at
the request of various competitors, which could lead to a variety of
interpretations, including the ones drawn from the Comprehensive
Drainage Plan. However, we’ve been encouraged by the TIRZ to assume
that the entire area is essentially a blank slate with regard to
infrastructure because those decisions are not final. Therefore, in
the interests of avoiding the imposition of a level of complication
that might delay the competitors, we decided it would be best to
select one outfall location and ask that everyone use it. As you
noted, it really won’t have any significant impact on the case for
LID and given fluid nature of the infrastructure decisions we feel
this is the best compromise.

Concerning the Urban Redevelopment design challenge:
Q: The competition literature states that Bastrop Street is to remain
in the public right-of-way. Are we to assume that vehicles and
parking
will be allowed on the promenade to access any development there, or
is it closed to vehicular traffic?
A: Bastrop Street itself is to be a pedestrian only venue. However the
cross-streets are to remain open for vehicular traffic.

Concerning the Suburban Residential design challenge:
Q: Does the road south of the school site with the sanitary easement
row
have to remain at this location and alignment? Would there be any
flexibility with the location of the sanitary sewer easement?
A: The road running south from the school site may be relocated or
eliminated. An easement ROW from the school property to the Sanitary
Sewer plant must be located in a viable and cost-effective manner. The
location of the Sanitary Sewer plant is fixed.
Q: Could you be more specific as to which roads around the school
site are to remain as part of the site plan? On Site Plan B, does it
just include the entrance road off of Peek Road turning right (north)
between the option tract and school site, then turning right (north)
again leading to entrance along Stockdick School Road?
A: The road shown on Site Plan B which follows the southern and
western boundary of (and internal to) the Katy ISD site, running
between Peek and Stockdick is the only road which is fixed and not
changeable. In a related matter, the tract labeled Option Tract will
now be occupied by the elementary school. A main entrance to the
development must be located on Clay Road.

Concering the Suburban Residential design challenge:
Q: Does the design analysis for drainage need to include the roadway
along the western, internal and southern boundaries of the school
site, or is the school including that in their detention calculations?
A: The school district will include drainage for the road in question
in their detention calculations.
Q: Does the cost of that roadway need to be included in the overall
cost estimate?
A: Assume that the road is to be constructed at the cost of the
developer, regadless of whether the project is developed traditionally
or using Low Impact Development practices.

Concerning the Green Roadway design challenge:
Q: Are the project team's designs to address the transition of the
proposed 4-lane roadway along Independence Parkway back to the
existing 2-lane roadways within the project boundaries? Or does the
transition occur outside the project boundary? Are there specific
transportation guidelines and roadway transitions that will be
established by the board for all project teams to implement?
A: The transitions are not within the bounds of the design challenge
limits. In order to avoid unnecessary complication, you are not
required to deal with the issues associated with transition.

Concerning the Green Roadway design challenge:
Q: It has been stated that conversion from a 2 lane road with roadside
ditches to a 4 lane thoroughfare costs roughly $5 million per mile.
What is the current standard 4 lane thoroughfare cross section which
this cost estimate is based on?
A: From HC Precinct 2: The typical 4 lane boulevard section for a 100’
ROW is two 12’ lanes each direction with a 32’ median face-to-face
with 10’ borders from face of curb to ROW line. Storm sewer is
generally in the median, but not absolute.
Q: The existing conditions hydrologic analysis assumes an area of
12.12 acres, which is a 100' ROW for 1
mile. Since our new roadway will be 120' wide (resulting in 14.54
acres per mile), shouldnt our existing conditions hydrograph represent
the runoff for the same area as the proposed new roadway?
A: A correction to the exisiting conditions hydrograph will be posted
later today. A notice will be made on this site when the updated
hydrograph is attached to the Green Roadway Design Challenge documents
at the main Competition website (
http://www.houstonlwsforum.org/designCompetition/Green%20roadway/GreenRoadwayDesignChallenge_09-24-09.pdf
).
Q: Since the existing conditions hydrograph includes only the roadway
ROW, should we assume for design purposes that we do not need to
account for areas outside our ROW draining to and being conveyed
through our roadway's drainage system?
A: Unfortunately, there are too many unknowns beyond the limits of the
ROW for outside drainage areas to be included.

Concerning the Entry Submittal which will be judged in Stage One of
the Competition, by the Expert Judges:
Q: If we have several layers on a single slide/page, in the PowerPoint
electronic submittal, and each layer “flies” in to demonstrate an
aspect of the design, will that slide still count as only one slide?
A: If you haven’t already, please view the Submittals Guidelines
document that’s linked in the Submission Requirements section of the
Competition Program (http://www.houstonlwsforum.org/designCompetition/
program.html#Requirements ). It addresses the desire to link multiple
pages to a single slides (and that’s ok for the entry submittal
although it will not be allowed in the Finals). Frankly, we don’t have
expectations that the entry submittals will be highly ‘produced' and
"flu in's" shouldn't be used. We chose PowerPoint as the format
simply because it seemed to be the most flexible and convenient
electronic medium for getting the information to us, rather than for
it's more elaborate presentation functions. We'd like the electronic
submissions to be simple so as to avoid any potential technical
difficulties which might negatively impact an entry's chances.
Q: Will the judges be viewing the slides/page in the electronic
submittal on projectors or individual computers?
A: There will be several laptops on hand along with a projector and
screen.
Q: Will sounds, music, and or narration be allowed to be built into
the PowerPoint electronic submittal? Will all judges have speakers
available while reviewing the slide shows?
A: Sound should not be utilized.

Concerning the Suburban Residential design challenge:
Q: Is there information available on the unit costs used on the
previous plan for the site (site plan A). This would be helpful for
the cost comparison on the submittal.
A: $50,000 per acre for internal (within each pod) paving and
utilities is a number used for budgeting purposes. Right now prices
are lower, but they’ll probably climb pretty quickly when development
picks up. For simplicity, assume 50% of that number is paving and 50%
is utilities. This number does not include plants or trunk lines in
the major collector streets (areas outside the pods).

Concerning the Suburban Residential design challenge:
Q: Stated in the Phase One Environmental Site Assessment there are two
soil types katy fine sandy loam and gessner loam. The hydrologic soil
groups for katy and gessner with a good hydrologic condition (grass
cover > 75%) are B (CN 61) and D (CN 80), respectfully. However, the
Predevelopment Hydrograph report concludes that the weighted adjusted
curve number (CN) for the site is 80. According to this 100% of the
site is gessner.
1. Please clarify how the predeveloped weighted adjusted curve number
was generated. What percentage of the site is katy and gessner.
2. Can the supporting documents/calculation for the predeveloped
runoff curve number be made public?
A: The Predevelopment Hydrograph report, assumes the less restrictive,
i.e., higher CN, for the entire site based on the limited information
available
to our tech advisory team. Although not intentioanally so,
this should make complying with the predevelopment hydrograph easier
on participants. No detailed documentation beyond that already made
available, and reasonable engineering assumptions, were used in
preparing the conceptual hydrograph.

Concerning the Green Roadway design challenge:
Q: Based on our visits to the green roadway project site and on the
LIDAR data for the project area it appears that the project drains
both to the north and south. The existing hydrographs provided for
the project only reflect one outfall at the north end of the project.
Please advise, are we to follow the single outfall hydrographs
provided or will an updated hydrograph be provided to represent the
actual project conditions.
A: The design challenges were simplified in areas that we felt
wouldn’t impact the viability of the solutions submitted in an effort
to provide a standardized set of guidelines and minimize unnecessary
complication. Limiting the number of outfalls was one of those areas.
Please assume that for either a traditional design or the LID design,
the single outfall is operative.

Concerning the Expert Judging process in Stage One of the competition:
Q: Can we get a feel for how much time the expert judges will be able
to spend on each submittal. This will help in the preparation of our
presentation, reports, etc.
A: The electronic submissions will be transmitted to the Expert Judges
shortly after all submittals are received on December 14th. Each Judge
will have the opportunity to review the submittals independently prior
to January 8th, when the Judges Meeting will be held. On that day,
laptop computers and projection system will be utilized in a
collaborative process of reviewing, scoring and determining finalists.
The foamcore presentation boards will also be on display in the
meeting room. This will be an all day meeting.

Concerning the Green Roadway:
Q: There are several granite historical markers in the Independence
Parkway ROW. These markers are the property of the State and they
cannot be moved. Should we assume that they should be addressed in our
design?
A: Given that we have not provided location data to competitors on
these markers, we don’t believe it is appropriate to require that they
be addressed within the scope of the competition.
Q: There are a number of old live oaks that were planted in 1936
(which have been sheared by the power company) on the west side of
Independence parkway. Are we to replace them?
A: Use appropriate prevailing landscape ordinances to determine the
status of any existing trees.
