Land Development Code
Under the existing code a homeowner is able to design a livable space in the attic above a 2 story residence (habitable attic).
Currently, habitable attic above a 2 story house is possible because the building height is measured to the mid-point of the highest roof plane. In the new code (per the current draft) building height will be measured to the highest point of the roof.
There is substantial difference between the mid-point of the roof and the highest point of the roof. As the current draft is written, the proposed LDC will essentially eliminate the ability to design habitable attics above 2 story residences.
The attic area with a ceiling height from 5' to 7' must be equal or greater than the area with a ceiling height of 7' or greater.
Do not count the attic area that has ceiling height less than 5'.
City of Austin, Land Development Code (LDC), is in the process of being overhauled between late 2018 to mid 2019.
SUBCHAPTER F: Residential Design and Compatibility Standards.
AKA: McMansion Rules;
F.A.R - ATTIC EXEMPTION
The habitable portion of an attic (including walk-in dormers) is exempt from the F.A.R. calculations if it meets all of the following conditions;
The roof that creates the habitable attic is;
not a flat roof,
not a mansard roof,
has a slope of 3 to 12 or greater
It is fully contained within the roof structure.
It has only one floor.
It does not extend beyond the footprint of the floors below.
It is the highest habitable portion of the building, or a section of a building, and it ads no mass to the structure. (Roof/attic dormers are allowed as long as they meet the rules relating to dormers, in this Subchapter. For dormers, the roof must encompass the dormer.)
50 percent or more of the area must have a ceiling height of seven feet or less.

As planned the Howard Water Utility used its emergency backup groundwater wells for water supply while a repair was made in the Central Brown County Water Authority (CBCWA) transmission line. The transmission main carries lake water from the Manitowoc Public Utilities (MPU) water treatment plant to the Village of Howard. The repair was completed a day ahead of schedule and Howard resumed the use of lake water yesterday. Howard water customers did not experience any water service interruptions or operational issues. The wells produce high-quality drinking water but does contain radium at levels slightly above the EPA standard. Radium is a contaminant that has long-term use health effects, however because the use was short term, the Utility does not believe that drinking the water during this time period was harmful to users health. The groundwater wells are regularly maintained, the water is tested according to regulations and are an approved emergency backup water source for these types of circumstances. The Utility did not receive any customer complaints about water quality while using its groundwater wells. The Howard Water Utility wishes to thank its customers for their patience and understanding during the transmission line repair project.

During winter, the team at Kennedy Plumbing & Gas gets many callouts in relation to faulty hot water systems. Many of the problems are caused by thermal expansion and contraction – a consequence of Canberra’s chilly winters. In this blog post, we answer common questions about hot water problems and repairs in Canberra.
Why do hot water systems often break down in winter?
Canberra’s sub-zero winter mornings cause many pipes and tank liners to freeze, expand and split. Splitting also occurs when pipes and tank liners revert back to their original shape (once the day warms up). Not surprisingly, older pipes and tank liners (that have lost their strength) are more likely to split; in other words, the cold weather exacerbates existing weaknesses.
What are the signs of a faulty hot water system?
There are a number of signs that indicate your hot water system might need professional attention:-
- Your water tank or piping leaks (probable signs of a split or rust).
- There’s rust-coloured water around the base of your water tank.
- There’s a distinct lack of water pressure when you turn on a hot water tap.
- Cold water flows from your hot water taps.
- Your hot water doesn’t last very long (or runs out very quickly).
- The pilot light on your gas hot water system has stopped working.
- Your hot water is discoloured (typically rust-coloured).
- There’s a strong smell of gas coming from your gas hot water system.
- Your water tank makes strange noises.
What should I do if my water tank starts to leak serious amounts of water?
You should turn off your water mains tap straight away, then call a Canberra plumber. The water mains tap is usually located at the front of your property (next to the water meter).
Why do so many outdoor hot water tanks rust at the base?
Many older outdoor hot water tanks are situated directly on concrete slabs – meaning that rainwater gets under them and sits there. Nowadays, hot water tanks are generally placed on a “pizza tray” to provide a 5mm drainage / air gap between the tank and concrete slab. A “pizza tray” is simply an elevated plastic tray with holes in it.
Does Kennedy Plumbing & Gas fix both gas and electric hot water systems?
Yes. We conduct both gas and electric hot water system repairs in Canberra. Our experienced plumbers repair the following system types: continuous flow gas hot water systems; gas storage hot water systems; electric storage hot water systems, and heat pump hot water systems.
As an experienced hot water plumber in Canberra, Kennedy Plumbing & Gas is certified to repair tempering valves (keeps maximum water temperature to 50°C) and replace DUO valves / pressure limiting valves. These are plumbing components that tend to fail over time.
If your hot water system requires an electrician, Kennedy Plumbing & Gas can take care of this too. We work with a number of quality electricians in Canberra and Queanbeyan. Common electrical problems include a faulty power supply, heating element, thermostat or electronic ignition (on gas systems).

Effective Sunday, March 1, spring service changes take effect as RTA begins to prepare for the closing of Public Square.
A total of 33 bus routes will have relocated stops and changed routes.
When the closure actually happens on a date to be determined in March, Ontario Street and Superior Avenue through Public Square will be closed to all traffic.
RTA says, generally, passengers will be directed to use the closest available stops outside the Square.
Buses that would normally travel along Superior and/or Ontario will use the perimeter roads to travel around the construction zone.

LIFE EBRO-ADMICLIM (ENV/ES/001182)
The project LIFE EBRO-ADMICLIM (ENV/ES/001182) puts forwards pilot actions for adaptation to and mitigation of climate change in the Ebro Delta (Catalonia, Spain), an area vulnerable to sea level rise and subsidence.
We propose an integrated approach for managing water, sediment and habitats (rice fields and wetlands), with the multiple aim of optimizing ground elevation (through inputs of inorganic sediment and organic matter), reducing coastal erosion, increasing the accumulation (sequestration) of carbon in the soil, reducing emissions of greenhouse gases (GHG), and improving water quality. This type of approach has not been applied so far in the European Union, and it is clearly innovative internationally.
The main pilot adaptation actions focus on sediment inputs from the Ebro River into its Delta. The aim is to demonstrate the feasibility of permanently restoring the sediment flow, both from a water treatment plant on the Ebro (Consorci d’Aigües de Tarragona, CAT) and from the reservoirs along the lowest stretches of the Ebro. Essential for this is a good assessment of the transport capacity of the river and the channels. Mitigation pilot actions are also proposed for the rice fields and wetlands, to optimize carbon and nutrient sequestration and GHG emissions, and increase the ground elevation.
The final conclusions drawn from these pilot actions will allow the elaboration of a Climate Action Plan for the Ebro Delta with specific and effective measures for the mitigation and adaptation of the area to the climate change.
Project duration: 4 years (June 2014 – June 2018).

Backfill settlement in new construction can cause the electrical service box to rip from the wall, resulting in potential exposure of service wires. It is common knowledge in our field that problems can develop with the connection of underground electric service to building structures. Specifically, problems have developed from the settling of backfill over the electrical conduit. It is not unusual for the backfill to settle from several inches up to a foot or more, along with the conduit surrounding the service. This shifting can expose service wires and cause the building service box to pull away from its anchoring. Even if the service wires are not broken or disconnected by the resulting tension, sections of the protective conduit around the service wires are frequently pulled apart or away from each other. In some cases there can be a breaking away of portions of the building structure to which the service extends. Problems such as these must be remedied.

Roof & Gutter De-icing
Many roof leaks are the direct result of snow and ice build-up in the gutter or along the roof edge. These ice dams create excessive pressure on the roofing material. The result is lifting and damaging the seal. When the ice melts, the water has no path to the gutter and/or down-spout and infiltrates into the structure.
During winter the temperature is often around zero degrees. At these temperatures large collections of ice and snow are often found on roofs and in gutters. This ice and snow can easily create hazardous safety concerns, especially when ice is falling from above. Installing Nexans heating cables on roofs and in gutters reduces the risk of falling snow and ice and ensures proper roof and gutter drainage preventing roof leaks and structural damage.
Evaluate the Roof Construction: Warm Roof or Cold Roof?
Warm roof: A poorly insulated roof where heat loss through the roof causes a positive temperature on the roof surface under a layer of snow. Water from melting snow will collect in the cold roof drains and freeze.
Cold roof: A well insulated roof where icing occurs, often in the late winter. Sunshine will melt snow on the roof while the roof drains and gutters may be in the shadow. The melting water will then freeze. Repeated occurrences will harm the roof and split gutters and downspouts.
Add together the total length of roof drains and gutters. The loop in the drain must go to point of discharge above or below grade. Multiply this length by 2 to determine the cable length.

Reuse of waste plastic in road construction is a suitable solution for the disposal of waste in an eco friendly way and thus avoiding the pollution created by the plastics in the environment. Presently the waste plastics are either land filled or incinerated. Both the processes are non technical and it will affect the environment in near future. In this context since the project of plastic road laying avoids land filling and incineration of waste plastics, it is considered as an effective process for the disposal of waste plastics.
Plastic tar road has double strength, compared to ordinary bitumen road. It can withstand both heavy load and heavy traffic. It is not affected by rain or stagnated water. And hence no pot hole is formed. There is no rutting and raveling. The life of the road is not less than seven years and there is no need for maintenance expenditure. Performance studies of the plastic tar road were carried out as per Central Road Research Institute specification and the results are very good. It has been published by CPCB and NRRDA as monographs.
Major road laying is done by the government only, either by Panchayat, municipalities or by corporations. The NHAI is doing major road works in India. The technology can be adopted by the consumers. India has not less than 41 lakhs Kms of road network of which 66, 000 Kms are Highways and 24, 00, 000 Kms are rural roads, state highways etc. More than 50, 000 Kms of roads have been already laid by using this technology. Nearly 11 states have started implementing the technology.


In a time where sustainable solutions are crucial for our future, permeable pavers have emerged as a game-changer in the construction industry. These innovative paving materials offer a ton of benefits, from reducing stormwater runoff to enhancing water quality and promoting eco-friendly urban development.
Permeable pavers, also known as porous or permeable interlocking concrete pavers, permit water to infiltrate the surface, replenishing underground aquifers instead of contributing to stormwater runoff. By preventing excess water from pooling on impermeable surfaces, these pavers help to reduce the strain on stormwater management systems and minimize the risk of flooding during heavy rains.
Water Quality Improvement
Stormwater runoff from conventional pavements often carries pollutants, such as oil, heavy metals, and chemicals, into nearby water bodies, harming aquatic ecosystems. In contrast, permeable pavers act as natural filters, allowing water to pass through multiple layers, effectively trapping and removing contaminants before they reach water sources. This leads to an improvement in water quality and fosters a healthier environment for aquatic life.
Heat Island Mitigation
Traditional asphalt and concrete pavements contribute to the urban heat island effect, causing localized temperature increases. Permeable pavers, on the other hand, have a higher reflectivity and lower heat retention, thereby reducing heat absorption and keeping the surrounding environment cooler. This cooling effect enhances the comfort of pedestrians and improves overall urban microclimates.
Cost-Effective and Low Maintenance
While permeable pavers may require a slightly higher initial investment compared to conventional pavers, their long-term benefits far outweigh the costs. Reduced stormwater management needs and potential tax incentives for implementing sustainable practices can lead to substantial savings. Furthermore, permeable pavers generally have lower maintenance requirements, resulting in decreased long-term expenses for property owners and municipalities.
Embracing permeable pavers is a pivotal step toward fostering sustainable and eco-friendly urban development. The numerous environmental benefits, coupled with improved water management, safety, and aesthetics, make them an excellent choice for the modern world. By choosing permeable pavers, we not only contribute to the conservation of water resources and the protection of ecosystems but also take a proactive stance in mitigating the impacts of climate change. It's time to pave the way to a greener, more sustainable future with permeable pavers.


Influence of junction and traffic characteristics on safety at road junctions in Dar es Salaam
University of Dar es Salaam
The study investigated the influence of junction and traffic characteristics on the safety at urban priority junctions in Dar es Salaam. Serious traffic conflicts were assumed to indicate safety problems at the junctions. Human observers recorded serious conflicts using the Swedish version of the traffic conflicts technique for three days at each junction. Data collected include classified traffic volume by movement pedestrian volume, speed, junction geometry and location, compliance to the stop rule at minor approaches, gaps in the major street traffic, and land use. Relationships between these basic variables and their derived functions and serious conflicts at aggregate and disaggregate levels were developed within the generalized linear modelling framework. It was assumed that traffic conflict counts were distributed according to the Poisson or negative binomial distribution. Analysis at the junction level gave results that are broadly similar to those based on accident data elsewhere. Analysis at the junction approach level showed that the volume of non-conflicting flows and pedestrians had a strong influence on the expected frequency for the vehicle/vehicle conflict types. Junction geometry, location and speed had significant effect on conflict frequency. The frequency of pedestrian conflicts was highest at junction exits. Turning vehicles were over-represented in pedestrian conflicts. The results confirm that the Swedish traffic conflict technique is a valid tool for safety analysis at road junctions in Dar es Salaam and in similar urban areas. The models may be used for identifying junctions with safety problems, in before-after studies to evaluate effectiveness of safety measures, and as a basis for identifying potential safety measures. It is also apparent that the ability of road users to acquire and process information is over-stretched at four-arm priority junctions with medium to heavy flows. Effective safety measures must reduce the road users' information load. Field validation of the models through before-after studies is recommended. The results of such studies are needed to confirm and refine the models and for the development of local knowledge of the effectiveness of safety measures.

Biogas plant in Kežmarok
Our company has been seeking for several years to find an opportunity for building a biogas plant with full use of both types of generated energy. We managed to build such biogas plant in Kežmarok. This plant is located at land of approx. one hectare and is close to an agricultural cooperative and at a distance of around 700m from the dairy plant where a cogeneration unit with an output of 999 kWel is installed. This plant is interesting given the fact that links between the operation of a biogas plant and an industrial production facility is a peculiarity in Slovakia. It is worth mentioning the good cooperation with farmers who are involved in this cycle. This where it all starts and ends: from the transformation of agricultural residues and biomass to biogas up to the use of the residues of biogas production – digestate for the purposes of fertilisation.
Given the chance to install the cogeneration unit directly at the place of heat consumption in the dairy plant, it is possible to use the maximum of generated heat. The dairy plant uses the heat from the cogeneration unit, the heat generated in the flue gas boiler in the form of steam, as well as heat from the cooling of the cogeneration unit turbine. Heat is thus produced at several technological levels and is used to the maximum extent possible, which means significant operation energy saving for the operator.
A standard level of heat generation consists of a motor block which combusts biogas produced by anaerobic fermentation in fermenters. Such heat has the form of hot water and is used for pre-heating the feed water for steam gas boilers, technological water heating, and the heating of buildings. Part of hot water is used for the heating of fermenters and storage areas used for the biogas plant operation. It is supplied from the dairy plant boiler-room by means of a caliduct.
The entire project is based on saving attained through power and heat generation with the help of biogas which replaces natural gas. Another benefit for the operator is the possibility to dispose of waste from dairy production (acid whey), for the disposal of which the operator would otherwise need to pay to the customer.
