Flower Mound Leader > News
Town creates video about proposed lake
From staff reports
In an effort to provide information to Denton County residents regarding the proposed Lake Ralph Hall and how it will affect water rates, the town of Flower Mound recently produced an informative video.
The presentation focuses on the Upper Trinity Regional Water District, its rates and its plans to construct Lake Ralph Hall in Fannin County, near the City of Ladonia. With this video, the town is encouraging residents to become involved and petition their community’s Upper Trinity Board Member to seek more economical water sources prior to the construction of the lake.
The cost to build the lake has been estimated to be from a low of $274 million to a high of $464 million, funded by the Upper Trinity Water District’s customers through rate increases. For years, the town has tried to persuade Upper Trinity to exhaust all viable alternatives prior to building the lake.
Flower Mound is contesting the permit from the Texas Commission on Environmental Quality allowing Upper Trinity to build Lake Ralph Hall. The town made a settlement offer to the Upper Trinity Regional Water District to withdraw its opposition as long as the water district took steps to explore other more cost efficient options prior to building the lake. The settlement offer was rejected by Upper Trinity.
Upper Trinity officials claim the lake is needed to supply water for the region to address the continued growth. They also claim Flower Mound’s water rates are high because the town subscribed to more water than it needed years ago.

Technology has revolutionized the way we interact with the world, and one area that has particularly seen dramatic advancements is geospatial technology. Geospatial technology involves the collection, analysis, and presentation of data about the Earth’s surface and its various features. When combined with the power and versatility of drones, these technologies open up a world of possibilities.
The Rise of Geospatial Technologies
Geospatial technologies have come a long way since their inception. Early maps were hand-drawn, providing limited information and often lacking accuracy. This all changed with the advent of Geographic Information Systems (GIS) in the 1960s. GIS allowed for the integration of diverse data sources, making it easier to analyze and visualize spatial data.
Today, geospatial technologies have become an indispensable tool for a wide range of industries. From urban planning and environmental management to transportation and disaster response, the applications are vast. With the inclusion of drone technology, the possibilities have expanded even further.
The Power of Drones in Geospatial Applications
Drones, or unmanned aerial vehicles (UAVs), have gained popularity in recent years for their ability to capture high-resolution imagery and collect geospatial data from a bird’s-eye view. Equipped with specialized cameras and sensors, drones can gather data more efficiently and cost-effectively than traditional methods.
One of the main advantages of drones is their ability to access hard-to-reach areas, such as rugged terrains, disaster zones, or construction sites. They can quickly and safely navigate through these environments, capturing data that would otherwise be challenging or dangerous for humans to collect.
Drones can be outfitted with a range of sensors, including thermal cameras, multispectral cameras, LiDAR, and GPS. These sensors allow for the collection of various geospatial data types, such as aerial imagery, 3D models, vegetation indices, and elevation data. This wealth of information can be processed and analyzed using GIS software, providing valuable insights for decision-making and planning.
Applications of Geospatial Technologies and Drones
The applications of geospatial technologies and drone technology are extensive and continually expanding. Let’s explore some key areas where these technologies are making a significant impact:
1. Environmental Monitoring and Conservation
Geospatial technologies and drones play a crucial role in monitoring and conserving our environment. By collecting aerial imagery and data, scientists can track changes in land cover, identify deforestation patterns, and monitor wildlife populations. This information is vital for designing effective conservation strategies and mitigating the impacts of climate change.
2. Urban Planning and Infrastructure Development
In urban planning, geospatial technologies provide essential data for designing sustainable cities and optimizing infrastructure development. Drones can capture detailed aerial imagery, map terrain characteristics, and detect patterns of urban growth. Planners can use this information to assess the impact of proposed projects, improve transportation networks, and enhance disaster preparedness.
3. Agriculture and Precision Farming
Geospatial technologies and drones have revolutionized the agriculture industry by enabling precision farming practices. Drones equipped with multispectral cameras can analyze crop health, detect nutrient deficiencies, and identify areas requiring irrigation. Farmers can use this data to optimize fertilizer usage, save water, and increase crop yields.
4. Disaster Response and Emergency Management
During natural disasters or emergencies, geospatial technologies and drones are invaluable tools for response and recovery efforts. Drones can swiftly assess damage, search for missing persons, and create real-time maps of affected areas. This data facilitates efficient resource allocation, aid distribution, and post-disaster reconstruction planning.
5. Archaeological Survey and Cultural Heritage Preservation
Geospatial technologies are transforming the field of archaeology by revolutionizing surveying and mapping techniques. Drones equipped with LiDAR technology can create highly detailed 3D models of archaeological sites, revealing hidden features and aiding in documentation and preservation. This technology helps researchers better understand our cultural heritage and plan effective conservation measures.
The combination of geospatial technologies and drone applications has opened up a world of possibilities, transcending borders and providing valuable insights into our environment, infrastructure, agriculture, and culture. As these technologies continue to advance, their potential to transform industries and drive innovation is boundless. Embracing these technologies and harnessing their power will undoubtedly shape the future in remarkable ways.

The Grenfell tower fire in London in mid-June was very tragic and resulted in 79 deaths. This terrible occurrence has highlighted the extremely negative impact that the choice of building materials can have. There have not been many significant advances in construction materials recently. The Colosseum in Rome was largely built with concrete, terracotta roof tiles were used on the temple of Apollo in Corinth in 700 BC, and plasterboard was invented in 1894. We see that due to the lack of advances in construction materials, a perception has developed that all building materials and construction techniques are safe and have been tested over centuries.
As a former building products analyst at a large US investment bank I have more than a passing interest in construction materials. In this week’s piece, we are going to look at the impact that plastic-based aluminium composite cladding may have on Australian direct property investors, and who is likely to pay the remediation costs when building materials go wrong. Looking at past examples, the home owner invariably has borne most of the costs for decisions that were not made by them.
Cladding is added to a building to prevent rain from entering the building’s structure, to improve sound and thermal insulation, and in many cases to improve the exterior aesthetics of a building. Aluminium cladding consists of two thin aluminium outer layers bonded to a mineral fibre core such as polyethylene or polyurethane. The issue is that not all of the polymers used in the honeycomb core are fire resistant, and indeed some of the cheaper polymers used are actually very flammable.
If the polyethylene core catches alight, the aluminium skin acts as a chimney to accelerate the fire up the outside of the building. The composite cladding used on the building in London was responsible for the 2014 apartment fire at Melbourne’s Lacrosse building and a number of fires in Dubai. In the Melbourne fire a cigarette left on a balcony table caused a fire to spread up the 13-storey tower in less than 15 minutes.
In the wake of the Grenfell fire, the Australian Society of Building Consultants estimated last week that there are 2700 buildings in Sydney utilising aluminium composite cladding, and 50% of the high-rise buildings built in Melbourne over the past decade also use it. The aluminium cladding commonly used in Australia and installed in Melbourne’s Lacrosse building is Alucobest which is imported from China and is cheaper than fire-resistant aluminium cladding such as Alucobond.
Whilst not all of the aluminium cladding used in these buildings is of the flammable variety, investors owning apartments with non-compliant cladding may face significant remediation costs, dramatically reducing returns. In February 2016 the Victorian Building Authority (VBA) found that 51% of the 170 high rise residential and public buildings around the Melbourne CBD had non-compliant external aluminium cladding. Paradoxically the VBA audit concluded that this did not pose a safety risk.
We would suggest that owners of apartments constructed over the past decade investigate whether the cladding used in the construction of their asset is of the fire-resistant variety. In the case of Melbourne’s Lacrosse building, owners of the apartments are still battling through the courts over who is responsible for the $15 million repair bill. Based on our crude calculations, this represents a bill of $100,00 per apartment, a significant sum for investors in an apartment building where two-bedroom apartments are being sold for between $400k and $500k. Research indicates that apartments were sold off the plan for ~ $300k in 2010, so the remediation costs may eat up most of the capital gains.
Chinese drywall (plasterboard)
Similar to the abovementioned Chinese made aluminium cladding was the contaminated plasterboard used in residential construction in 100,000 homes in the US between 2001 and 2009. During the homebuilding boom in the US last decade, there was insufficient local production of plasterboard which caused builders to source Chinese-made plasterboard that also happened to be cheaper. The high levels of pyrite in the cheaper Chinese-made plasterboard resulted in the release of sulphur gas into the home, which is bad for respiration of residents and also causes corrosion of copper pipes in the walls. The remediation costs are quite significant with costs being around US$200,000 to remove and replace the plasterboard on an on a four-bedroom home.
Despite major importers of the plasterboard being companies the giant German building materials company Knauf, affected homeowners were eventually limited to claiming only a tax deduction after replacing the plasterboard.
Who pays? Leaky homes in rainy places
In New Zealand and British Columbia, changes to the building codes in the 1990s resulted in the uptake of building materials and construction methods more suited to the sunny Mediterranean, rather than the rainy South Island of New Zealand or Vancouver where it rains on average 160 days per year. The change resulted in buildings with minimal eves to disperse rain and wrapped in a fashionable textured cladding such as stucco or fibre cement. As water gained entry into cracks in the building structure, the timber frames began to rot and mould developed.
Despite the cause of these building calamities being changes to government construction policies, the owners of the buildings ended up bearing most of the costs of remediation. In New Zealand after many years of litigation and builders going into administration, a bailout package was put together. This the split the costs with 64% covered by the property owner, 26% local council and 10% Federal Government. In Canada, the situation was even grimmer for property owners, with the best offer being an interest free loan and tax relief.
Whilst many would assume that builders or developers would be responsible for replacing aluminium panels that are susceptible to fire, the above examples strongly suggest that owners of property with this material installed are likely to bear the costs of replacing the problem building materials.

taken from the firemain through a duplex strainer and a
flow regulator (orifice plate) to and through the heat
exchanger. It is then discharged overboard. The
connection to the firemain is permanent.
The ships fire pump, not shown in figure 1-7, is
used to pump seawater into the firemain. The fire pump
is similar in design to the previously mentioned seawater
circulating pump, except it has a much larger capacity.
Another means of getting seawater as a primary
coolant is by an emergency connection (figs. 1-6 and
1-7). This method is used if the normal seawater supply
is lost. The connection is usually by means of a 1-inch
fire hose. The emergency supply comes from an
alternate portion of the ships firemain or a portable
pump rigged by the ships damage control party. The
portable emergency hose is normally stored in the liquid
coolant machinery room.
Note: Seawater systems are referred to as
open-looped or one-pass because the seawater flows
through the system only once.
In figures 1-7 and 1-8, chilled water is taken from
the supply main of the air-conditioning, chilled-water
systems. The chilled water is used as a backup source
of cooling water for the primary cooling system shown
in figure 1-7, and as a normal and backup source in the
system shown in figure 1-8. The chilled water flows
through the tubes of the heat exchanger (chilled water
to distilled water), a flow regulator, and back to the
chilled-water system. A temperature regulating valve at
the inlet of the heat exchanger regulates the flow of
chilled water through the heat exchanger to maintain the
required water temperature in the secondary system
The ships air-conditioning,
chilled-water circulating pump is used to pump the
chilled water through the heat exchanger. The
chilled- water system is a closed-loop water system
because the water is recirculated. It must be kept tight
and free from leaks to assure satisfactory operation.
SECONDARY COOLING SYSTEM
The secondary cooling system is designed to
transfer heat from the electronic equipment being
cooled to the primary cooling system. This system is
usually comprised of a distilled- water circulating pump,
a compression or gravity-feed expansion tank, the

Railroad crosstie replacement project UPDATED
UPDATED on Friday, May, 24:
After releasing a schedule for work on railroad crossings in Elberton on Thursday, Friday that schedule was tossed in favor of a schedule that has most of the work being done in Elberton at the end instead of at the beginning of the schedule.
Ray Porter, a consultant with Benchmark Consulting representing CSX Railroad, said that work on the west end of Elberton, including two at Eagle Granite and Whitlow Electric, will be at the beginning of the regular schedule for the crossings.
Originally, the work was going to begin on the east end of town and proceed west all the way through town.
Instead, there will be work on the two private crossings at Eagle and Whitlow, and work will proceed west all along Highway 72 to Madison County.
At the other end of the town, the work will actually begin in South Carolina and work its way west into town, with the crossings in Elberton on the east end of town beginning, mostly likely the weeks of June 10 or June 17.
A crosstie placement project will begin Tuesday and will temporarily close 31 CSX railroad crossings throughout Elbert County. The project is expected to be completed in about two weeks.
The project will affect all public and private railroad crossings and will begin at Johnsontown Drive then follow east to west until Crystal Drive, which is when the project will move into Madison County.
According to Porter, the project will have a "domino effect" meaning not all railroad crossings will be closed at once, but will instead close and re-open as the crew moves throughout the county. "When one is done, we go down," he said.
Porter told Elbert County law enforcement and emergency services in a meeting Thursday afternoon that the crews will work from 6:00 p.m. to 5 a.m. throughout weekdays until the project is completed. He said that each crossing will take two or three days and that it should be even quicker since crews are working at night.
More high traffic railroad crossings to be effected are Heardmont Drive, Middleton Church Road, Old Middleton Church Road, Jenkins Road, Seaboard Street, Williams Street, Willow Street, Locklin Street, Mill Street, Campbell Street. McIntosh Street, Harper Street, Granite Plaza, Brewers Bridge Road, Victory Road and Sweet City Road.
Porter said that the North Oliver Street crossing is not a part of the project right now since it is a state highway and is regulated by the Georgia Department of Transportation.
"We want to give as much active information out to our communities so they know what's going on," Elbert County Emergency Services Director Chuck Almond said. "When it comes to the railroad, it cuts this county in half ... we want to try to be prepared," Almond continued.
The projected is expected to be completed by June 11 in Elbert County and is a part of a larger project that will span over four weeks and will go from Abbeville, South Carolina to Athens.


Certification to NSF/ANSI 61
Protective coating systems used in North America for potable water application are required to comply with NSF/ANSI 61: Drinking Water System Components – Health Effects by most governmental agencies that regulate drinking water supplies.
Certification to NSF/ANSI 61 ensures that the coating product meets the regulatory requirements for the U.S. and Canada, and it can often meet or fulfill the testing requirements for many other countries as well. NSF/ANSI 61 testing covers all products with drinking water contact from source to tap, and determines what contaminants may migrate or leach from your product into drinking water. It also confirms if they are below the maximum levels allowed to be considered safe. The NSF certification as a mark of distinction provides the customers with assurance that the certified product is safe for use in drinking water.
For potable water pipeline application, American Water Works Association (AWWA) Standard AWWA C210 Liquid-Epoxy Coating Systems for the Interior and Exterior of Steel Water Pipelines sets minimum requirements for shop- and field-applied, liquid-epoxy interior linings and exterior coatings used in the water-supply industry for steel water pipelines installed underground or underwater, under normal construction conditions. AWWA Standard C222 Polyurethane Coatings for the Interior and Exterior of Steel Water Pipe and Fittings sets minimum requirements for shop- and field-applied polyurethane interior linings and exterior coatings used in the potable water supply industry.
Strathmore’s Coating Subject Matter Experts are the leaders in developing potable water coatings. As a matter of the fact, the very first edition of the AWWA Standard C222 standard was drafted by one of our Strathmore’s Coating Subject Matter Experts. We have abundant experience in designing, formulating, applying, and inspecting coatings and linings used for potable water application. Strathmore offers Strathane PW - a 100% solids, 1:1, high performance potable water grade polyurethane coating as per AWWA C222.

The farm is crossed by two streams.
Snake Creek is a perennial, gaining stream. A perennial stream flows all year except in severe drought. A gaining stream flows below the water table and receives water via springs or seepage. Groundwater flow is augmented by surface runoff during wet weather.
The designation as a perennial stream is questionable since the stream “flows” only after snow melt or rain events; however, there are many places where the stream bed intersects the water table, resulting in seepages.
Characterizing Snake Creek as “gaining” is also debatable. Some streams contain both losing and gaining reaches. Flow may be lost into the subsurface in a losing segment, while groundwater from seeps or springs may provide flow in another gaining reach. So, while the presence of seeps may make Snake Creek technically a gaining stream, it is nevertheless dry over most of its length (on the homestead) most of the time.
Snake Creek originates to the north of the homestead and continues across the property to the south. At all points as it crosses the farm, Snake Creek flows through heavy forest. Snake Creek cannot support aquatic life, is not easily accessible, and has no recreation potential for swimming or fishing.
Snake Creek has no value as a source of water. The lack of mass (flow) and head (vertical drop) means that Snake Creek is not a source of useful energy.
Sheep Creek (not a recognized name) is an ephemeral, losing stream. Sheep Creek is a losing stream since it “loses” its water into the water table. Sheep creek does not support aquatic life. Sheep Creek, as currently configured, has no value as a water or energy source, nor does it have inherent potential for water-oriented recreational activities.
Given expectations for the need to capture water when available for future use, it may be practical to create a catchment (pond) to collect water from the stream when the stream is flowing. Ideally, the pond would be designed with an outlet for controlling small amounts of excess water and a spillway for larger overflows.
The farm hosts three ponds.
Ponds store water when it is plentiful to be used when water is scarce.
Pond water is not potable by humans without treatment. Pond water may be suitable for use by livestock. However, to preserve pond integrity and water quality, it is important to drain water from the ponds to stock tanks and to prevent direct access to the ponds by livestock.
Ponds may be used as reservoirs for water to be used in firefighting if the ponds are close enough to the affected structure. It is possible that water from the small pond has firefighting reservoir potential for the hay barn; however, no pond is close enough to any proposed home sites to be of value in firefighting.
Ponds may be used for recreation, including swimming and fishing. Recreational use requires that the water be of sufficient clarity and be free of pathogens. For fishing, the ponds must be stocked and the fish population must be managed.
(Taken from Missouri State Water Plan Volume II, Water Resources Report #46, Groundwater Resources of Missouri)
The homestead sits atop the Salem Plateau within the Ozark Aquifer. The thickness of the aquifer is in the range of 600-1000 ft.
Yields of domestic wells 250 to 350 ft deep that are drilled into the Roubidoux, range from 15 gpm to about 35 gpm in the Salem Plateau groundwater province.
Water from the Roubidoux Formation tends to be relatively “hard” water with significant amounts of dissolved minerals, as seen below.
Streams on the homestead are not a useful source of water.
Ponds are useful as water storage for livestock. If carefully managed, they may have some recreational potential for swimming and fishing. The little pond may be of some use as a water source for fighting a fire in the hay barn, but no ponds are close enough to proposed home sites to be of use for fire fighting.
The Ozark Aquifer offers fresh water at the rate of 15-35 gallons per minute from a depth of between 250-350 feet. Water quality is acceptable but the water is “hard” with dissolved minerals.


Air infiltration through unplanned inlets is an integral component of any ventilation process. Air infiltration affects the quality of the room environment and can also increase winter heating costs. Precise data on air infiltration is very important in the design of animal room ventilation systems. Nineteen mechanically ventilated (negative pressure type) swine finishing rooms in Iowa were tested for their air infiltration potential. Using the data of 17 rooms, air infiltration rate through the whole room (i.e., total air infiltration, It), curtains (Ic), fans (If) and net building shell (other components, Io) were quantified. Power law equations were developed for infiltration prediction of different room configurations grouped on the basis of their construction style, age, ceiling material, curtain perimeter, and fan backdraft shutter area. All power law models reported in this study were adjusted to predict standard (sea level) infiltration rates. At 20 Pa pressure difference across the room envelope, the predicted standard It infiltration rate for the 17 rooms was 5.96±1.49 air changes per hour (ACH); whereas, the predicted standard Ic, If, and Io infiltration rates were 1.49 ±1.00 ACH (about 25% of It), 1.52 ±1.38 ACH (about 26% of It) and 2.90 ±1.42 ACH (about 49% of It), respectively. The standard It infiltration rate trended lower for rooms (n=8) from single room layout barns (5.85 ±1.66 at 20 Pa), rooms (n=8) having a non-metal ceiling (5.85 ±2.15 at 20 Pa), and rooms (n=8) aged ≤ 13 years (5.85 ±2.15 at 20 Pa). The infiltration resistances, calculated using standard sea level infiltration rates, indicated that the curtain, fan, and other infiltration areas of swine finishing rooms changes with barn layout, age, construction material, and pressure difference. Methodology to convert measured infiltration rates to standard sea level weather conditions and to any desired room location was included.

As trucking and train traffic in the The Avenue 66 Grade Separation project was in the works for more than a decade. As trucking and train traffic in the regional freight corridor increased, and the community continued to grow, a safe and reliable access point in and out of Mecca was critical. This new, 800-foot long bridge crosses Hammond Street, the Union Pacific Railroad and Highway 111, to safely connect cyclists, pedestrians and vehicles from Mecca to Avenue 66 and Highway 111. The project also helped reduce travel delays and congestion at the 4th Street at-grade crossing.


Bay Bridge East Span Tour Inspires Dublin High School Engineering Academy Students
Dublin High School Engineering Academy students capped an exciting year, that included meeting MythBusters stars Adam Savage and Kari Byron, winning at RoboGames 2012 and building a duct tape suspension bridge, with an exclusive boat tour of the new east span of the San Francisco – Oakland Bay Bridge. The new $6 billion bridge, scheduled to open in 2013, has been engineered to withstand a 1,500 year seismic event. Led by Bay Bridge Seismic Safety Projects Educational Outreach Program Manager Steve Padilla, Dublin High School Engineering Academy students learned about the science and engineering decisions behind the new bridge’s design, as well as the story behind a special iron troll crafted by construction workers to protect the existing bridge. The material used to create the troll was taken from a portion of the Bay Bridge that collapsed as a result of the 1989 earthquake (watch the video for a close-up view of the troll, created by construction workers after the 1989 earthquake).
“When engineers design structures to resist earthquakes, they use ‘rock motions’ to help them calculate the maximum seismic forces that the structure may experience; they then design the structure to resist these forces. Rock motions are the vibrations that travel through the bedrock caused by the slipping of an earthquake fault. Seismologists develop the rock motions based on the structures location in relation to earthquake faults and historical and geotechnical site data. The ‘new’ East Span has been designed to withstand rare seismic events. Specifically, the span has a 1,500-year return period. This is defined as the largest rock motions expected to occur at the bridge site once every 1,500 years.” – Bay Bridge Seismic Safety Projects website
The Dublin High School Engineering Academy curriculum expands in 2012-13 to include a new course, Digital Electronics, as well as a 1:1 computing pilot for students entering the academy.

Building Control will need to be consulted to check over the choices of construction, fire escape, and carbon footprint.
An essential difference in the most general terms is that while Planners control the impact of a building on the neighbourhood Building Control ensures the building is safe to use.
One demanding part of the Building Regs is ‘part L’, which deals with carbon emissions and will determine the level of insulation needed and how much glazing you must not exceed. This can require complex calculation and may be beyond our skills as an architect. If we need a consultants advice we shall tell you.

Bridge extension project at Tairua comes in on time and within budget. 10 December 2015 The official opening of the bridge extension at Manaia Road Causeway in Tairua was celebrated today with the local community, our Council and Regional Council staff and elected members coming to cut the red ribbon. The completion of the bridge work has seen it extended by 16m. The Regional Council is now underway with stop-bank and re-contouring improvement works of the flood plain and Graham's Creek channel. That work, in conjunction with the bridge extension, will help keep the road open during flooding and allow floodwater to drain more easily. "The completion of the bridge extension has come in on-time and within budget which is a successful result," says Thames-Coromandel District Council Mayor Glenn Leach. "We want to thank all the contractors and staff who have been involved through either the build, or management, of the project. And we want to thank the community for their patience while road diversions and closures were in place in some areas around Tairua during construction." "This project has seen a strong and focused collaboration between Regional and District Council and our stakeholders working group which is looking to produce a really good result," says Bob Renton, a member of the working party and Tairua-Pauanui Community Board Chair. "We are so pleased a workable solution was found and we've seen a successful outcome so far," says Mr Renton. "This is what can be achieved when locals are involved in decision making that affects the local community." Our Council funded approximately $930,000 towards the project with the Regional Council allocating $600,000 toward flood management and improvements around Graham's Creek. The Bridge extension took approximately 6 weeks to complete and the floodway and stop-bank construction being managed by the Regional Council should take around 12 months. This will be followed by restoration planting in the area which will be completely finished in 2017. Some 12,000 plants may be put into the ground and community volunteers will be asked to help.

In many European cities prices in the residential market are literally going through the roof and there is an acute need for action: as much affordable housing must be provided as quickly as possible. Yet how can costs be reduced without restricting the quality of the new homes? This calls for persuasive models and concepts that are cost-effective, sustainable and fit for the future.
The DETAIL volume Affordable Housing. Cost-effective Models for the Future documents fifteen outstanding current housing developments from all over Europe, which are distinguished by their quality but also by the fact that they were realised with reduced construction costs. Design solutions, deliberate material selection, specific building processes and explicit planning requirements all contributed to this result. The selection of current projects from such cities as Berlin, Paris, London or Zwolle are documented in depth with photos, texts, floor plans and detailed 1:20 scale drawings and thereby provide insights into the various concrete measures taken to reduce the building costs. Financing and corresponding funding instruments, reduction of construction costs and the rapid implementation of residential housing are crucial challenges for architects and the developers. Not only are considerations of floor plans, but also the careful choice of building materials together with their constructive applications as well as social aspects decisive approaches in this context for the final architectural solution. The introduction of the book includes several essays that highlight all of these challenges, presenting different perspectives and discussing historic as well as current examples. Planning methods and processes on site are addressed which can contribute to the reduction of building costs. But also social aspects and historical connections are picked up, such as in the example from Vienna - a metropolis that is recognised as exemplary for its subsidised housing.
This book is aimed at everyone who is involved in this responsible task of satisfying the steadily growing demand for affordable housing. It gives some ideas on how reducing costs in providing new homes does not have to mean sacrificing on quality for the residents as a consequence.

The Whistler Train Wreck is a popular, low elevation hike in Whistler. The short trail takes you to the site of a historic train wreck that happened in 1956.
In 2016, a suspension bridge was built over the Cheakamus River, making this an easy hike. Before that, the train wreck was a lot harder to access (requiring illegally crossing train tracks). The area has gained a lot of popularity since the bridge was put in.


After the severe earthquake in Japan in March 2011, they were the first to provide images from inside the destroyed reactor blocks of the Fukushima-Daiichi nuclear power plant: Unmanned Aerial Vehicles – also known in the technical literature as Unmanned Aerial Vehicle (UAV) or Unmanned Aircraft System (UAS). However, UAS have so far had little presence in the field of civil applications, especially in Europe. Within the scope of this study, the potential civil areas of application of UAS were identified and critically examined from 2011 to 2012. The aim was to highlight both the advantages and the limitations of unmanned aircraft. Based on the specific characteristics of UAS, they were compared with existing alternatives already in use for civil observation missions and their potential for use was evaluated. Special attention was paid to the support of UAS in disaster management and the use of UAS in homeland security.

Kathmandu. The reconstructed 22-storey Dharahara has got its 330-kg pinnacle installed on Wednesday. The pinnacle installation work was undertaken in the morning ritually and in the presence of the concerned authorities including CEO of the National Reconstruction Authority Sushil Gyawali.
The Nepali Army had blown trumpet while Mangaldhun was played and Swasti Bachan (recital of mantras for peace) were conducted during the pinnacle installation process. Made up of brass, the gold-plated pinnacle has also mix up of 95-kg gold.
The 22-storey rebuilt tower will be inaugurated on August 24, on the eve of the day when the 7.6-magnititude Gorkha Earthquake had rattled the country in 2015.
Prime Minister KP Sharma Oli is scheduled to inaugurate the rebuilt 72-metre tall tower that was first built by the first Prime Minister of Nepal Bhimsen Thapa in 1835 BS.
Heritage expert Rajuman Manandhar shared that CEO Gyawali had installed a Shivalinga in the 21st storey of the tower and had performed puja on the Shivalinga and the pinnacle.
Though Dharahara that spans across 42 ropani of land in total will be inaugurated in few days, it will not be open for public for some more time since other structures were under-construction. Manandhar said that it may take until November for the Dharahara to be opened for the public.
Public ought to wait until coming November to climb the tower and savor a panoramic 360 degrees view of the Kathmandu Valley.
Dharahara originally had 18 storeys. It was reduced to 11 floors following the 1990 BS (1934 AD) major earthquake. The reconstruction of quake-ravaged Dharahara had hit a snag for the first three years after it was reduced to the rubbles. The reconstruction process gained momentum after PM Oli officially laid found for the reconstruction of Dharahara on 27 December, 2018.


Lands Design is a technical software for Landscape design with BIM technology. It works as a powerful tool for 2D technical drawings, 3D modeling and photorealistic images of landscape projects. Some of the features of Lands Design are;
- Plant database with more than 8000 species: search and insert plant species, each one with their own technical specifications and detail characteristics.
- Setting out plans and Landscape project documentation: automatically generate 2D technical plans of a landscape project and create lists to quantify the information of the plant species, zoning areas, watering systems, etc.
- Realistic images, virtual tours: lands design includes libraries with real trees, each one with textured materials on leaves, branches, trunks and flowers. They can have different render appearances for season change simulation.
- Customize and edit vegetation species: assign custom 2D and 3D representations to each plant species. The tree editor allows to easily customize the appearance and shape of any plant with textures and materials, from the trunk to the tiniest leaf.
- 3D Terrain modeling tools: create terrains from contours, elevation curves, point clouds or import terrains from Google Earth. Lands Design includes a set of tools to easily modify terrains, calculate the volume of land movements, apply cut and fills, hollows, etc.
- Civil Work: create paths, stairs, dwarf walls, fences, or element rows for your landscape project.
- Watering system tools: define the watering installation using different sprinkler types, sprinkler distributions, and pipes.


To follow are the (13) Tasks outlined in the Water Quality Improvement Grant application.
Task 1- Accounting, Clerical and Administrative - This task will be ongoing throughout the Program life and will include keeping accounting records, receiving and disbursing funds and preparing reimbursement requests for Program activities.
Task 2 - Program Technical Management - This will include preparing quarterly reports, performing inspections to assure compliance with design documents and approving of progress and final payments.
Task 3 - Website development - This task will include creating the Oak Creek Watershed Council Website and posting the water quality data from Oak Creek along with the past, present and future Program activities. The site will be updated quarterly with new and supplemental information from the Oak Creek Watershed Council including meeting minutes and the Watershed Based Plan, (WBP). This task will also include collecting available pertinent water quality data from a variety of sources. Friends of the Forest, Arizona State Parks, Coconino National Forest, DWR and other groups also collect water quality data. Summary results of this information will be made available to the public through the Oak Creek Watershed Council Webpage.
A site map of Oak Creek Canyon showing toilet and shower facilities and other pertinent site information will be posted to the website.
Task 4 - Interagency Partnering - This task involves sharing the coliform data collected by governmental agencies partnering in the Program. Discussions will be held bi-monthly to allow the collected data to be presented by each agency or group and to discuss the solutions for improving water quality in Oak Creek. The discussions will occur as part of regular Oak Creek Watershed Council meeting presentations and will also be used to solicit interagency cooperation in the design and construction of new sediment traps, showers, and public restrooms.
Task 5 - Keep Oak Creek Canyon Beautiful Program - The Keep Oak Creek Canyon Beautiful Anti-littering Program, managed by the Oak Creek Watershed Council, will organize a group of volunteers to meet the visiting recreational public entering Oak Creek Canyon during the three summer holiday weekends. Trash bags, trash dumpsters, signage and portable toilets will be provided to the public to assist them with the “Leave No Trace” form of recreation. T-shirts with a message will be sold and given away to promote the program. The media will provide a significant role in educating the public. Volunteers will be scheduled to provide daytime surveillance of problem recreational areas. Trash will be collected before and after the weekend to track the benefits of this program in reductions to trash and human waste deposits in Oak Creek Canyon.
Task 6 - Site Suitability - A site/soil suitability analysis will be performed for the Indian Gardens Visitor Center site and used for designing an appropriate on-site wastewater system. Collection of topographic and soil information will be performed in order to design the on-site wastewater system upgrade. The existing septic tank system will be investigated and evaluated.
Additionally, a site/soil suitability analysis will be performed adjacent to the Cave Springs campground showers for design purposes for the graywater treatment and disposal system.
In preparation for the Phase Two grant submittal in September 2004, one or two additional site/soil investigations will be performed for one or two additional shower facilities. The sites of the second and/or third showers are projected to be at Indian Gardens Visitor Center and/or Pine Flats Campground. The site investigation work will be performed as a part of this grant to determine if one or two more showers will be included in the Phase Two grant application in September 2004. The design criteria will be developed and conceptual designs prepared in Task 7. This will allow Coconino National Forest staff to budget and prepare for the archeological, biological, NEPA and master site plan work necessary to pursue a grant application for construction funding in September 2004.
In preparation for the Phase Two grant submittal in September 2004, a site/soil investigation and analysis will be performed at Slide Rock State Park to evaluate the suitability and location for treatment and disposal facilities. The design criteria will be developed and conceptual designs prepared in Task 7. This will allow State Park Staff to budget and prepare for the archeological, biological, NEPA and master site plan work necessary to pursue a grant application for construction funding in September 2004.
Task 7 - Design Restroom, On-site Wastewater Treatment System and Sediment Traps - The Indian Gardens Visitor Center wastewater treatment and disposal system and water supply, will be designed to accommodate future expansion of the public toilet facility and provide for the addition of future showers. The tank placement and disposal field location will provide area for expansion.
A treatment and disposal system will be designed at Cave Springs Campground to provide treatment and disposal of shower graywater effluent. The site has suitable and available land area to accept the waste flow. The capacity of the system will be designed to accommodate an anticipated peak daily flow of 1500 gallons per day.
The Indian Gardens Visitor Center restroom building will be constructed adjacent and connected to the existing visitor center or constructed as a separate structure as approved by Coconino National Forest Staff. One side of the existing building could be remodeled to accept one toilet and one urinal and the other side of building could have an addition to accept two more toilets. ADA requirements will be met for a unisex handicap toilet at this facility. The design of the restrooms, Phase Two future shower facilities and the on-site wastewater and graywater systems will require a partnering effort between Coconino National Forest, RRM (the Coconino National Forest concessionaire) and the designers. An architectural designer may design the facilities or they may be a prefabricated structure. The restroom facilities will be blended into the existing Indian Gardens Visitor Center architecture through similar materials and colors. Landscape features of the on-site system and the restrooms will be incorporated.
A site suitability analysis will be conducted for each sediment trap site that will include identification of the contributing watershed area, sediment loading potential, topographic features and constructability of the facilities. Following the Interagency Partnering discussions, sites will be selected for sediment trap facilities. Permission to design and construct the facilities will be obtained from property owners, Coconino National Forest and ADOT. The Oak Creek Canyon site map will be updated to identify the locations. Pictures will be taken to document the pre-existing conditions. It is expected that at least 10 sediment traps will be installed during the Program. The design of the sediment traps will require a partnering effort between the agency property owner (Coconino National Forest), private property owners, ADOT and the designer. Final location of the traps will establish the design parameters and constraints. A sediment trap may be designed for a 10-year storm event. On the other hand, a second supplementary site may be selected to install a second trap in series to accomplish the sediment removal necessary. Available local rock materials and landscape plantings will be specified to ensure environmental integration with the natural surroundings.
Based on the site/soil investigations and discussions with Coconino National Forest staff, future shower facilities will be conceptually designed and cost projected for the September 2004 grant cycle. The location of these facilities will be Pine Flats Campground or the Indian Gardens Visitor Center.
A determination will be made during the site/soil investigation for future showers to be located at Indian Gardens Visitor Center and/or Pine Flats Campground. A conceptual design will then be generated along with cost projections for Phase Two funding in the September 2004 grant cycle.
A design review with Slide Rock State Park Administration will be performed to determine the size and location of showers, new flush toilets and an on-site waste treatment and disposal system. A conceptual design will be generated along with cost projections for Phase Two funding in the September 2004 grant cycle.
Task 8 - Design Approval - It is anticipated that a number of agency approvals will be needed. Any work planned within the right of way for State Route 89A will need ADOT approval. The Coconino National Forest will need to review and approve the sediment trap plans on Coconino National Forest property. Coconino National Forest will need to review the restroom and shower facility designs.
The on-site wastewater treatment and graywater systems will first be reviewed and approved by the Coconino National Forest and then by the Coconino County Environmental Health Department. Coconino County will assist with site/soil investigations and determining any limiting site conditions.
Coconino County will need to perform site surveys of the proposed on-site wastewater and graywater disposal systems in order to determine any limiting site conditions as outlined in Task 6. Permit fees will be associated with these site visits and limiting site condition determinations.
Task 9 - Access Node Signage - Bi-lingual signs will be designed and installed at the most frequently used creekside recreation sites. These signs will convey the concepts being promoted to reduce litter and promote developed restroom sites during peak occupancy of Oak Creek Canyon. We plan to design, construct and install four trailhead signs.
Task 10 – On-site Wastewater and Graywater System Construction – Following Coconino National Forest and Coconino County review and approval of the on-site system designs, the wastewater treatment and disposal systems and water supply will be constructed by a licensed contractor and/or a composite of donor/hire resources committed to providing materials, labor and equipment services.
Following review and approval of the restroom facility, the building addition and toilet fixtures will be constructed by a licensed contractor and/or a composite of donor/hire resources committed to providing materials, labor and equipment services.
Following review and approval of the state, federal and private property owners, the sediment traps will be constructed by a licensed contractor, by volunteer efforts and/or a composite of donor/hire resources committed to providing materials, labor and equipment services. The Coconino National Forest has budgeted staff time to assist with site selection and management of contract personnel.
Task 11- Program Completion Workshop - An interagency/neighborhood workshop will be held to present the Program results. Program results will be posted on the Oak Creek Watershed Council Website. Even though water quality monitoring is not a part of this grant request, volunteers and Slide Rock State Park personnel will perform periodic water quality testing for coliform bacterium. The results will be made available on the Oak Creek Watershed Council Website.
Task 12 – Pilot Project to Mitigate Odor from Vault Toilets – Odor and corrosive gas reduces the publics’ desire to use these facilities. Frequently, interior air quality is without odor, however, vented gas creates an odor around and near the restrooms that discourages use. Through engineering and research we will attempt to locate a viable solution and test the performance and cost effectiveness of the odor reduction method chosen.
Task 13 – Final Report - A final report will be prepared that documents all design work, drawings, photos and other pertinent data. This report will be provided in hard copy and digital copy.
