Revisiting the impact of mega infrastructure development.

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

The nature of mega infrastructure projects is such that their impact goes beyond its physical dimensions and boundaries. The impact goes even beyond its defined catchment, described objective, perceived externalities, and statutory confine.

When a mega infrastructure of any kind is introduced in a geographic system, the morphology of the immediate and distant built environment is either going to be evolved, shaped or redefined, ecological and bio-diversity reconfigurations may just get triggered, microclimate are going to undergo changes, socio-economic and demographic equilibriums are bound to change, power dynamics are bound to shift, a period of destabilisation and adjustments are sure to be witnessed, the upheaval of opinions, emotions and aspirations are mostly assured, the opportunity-scape are obviously to be developed and redefined, and vested interests are bound to surface, and of course, few consequences beyond human grasp may also surface.

Build a ring road, make an airport, build a dam, or channelize a river, and all or most of the above phenomenon gets activated and rarely gets acknowledged or addressed in their impact assessment in the totality, complexity, and subtlety of it.

There are certainly positive externalities, but currently, any (negative) impact of mega infrastructure that comes as a surprise, we tend to label them as unintended or link them to external factors or define them as non-linear and characteristics of wicked problems.

The possible reason for the shortsightedness of impacts and events followed by the advent of mega infrastructure are the practical limitations of prescriptive statutory compliance. That is understood, as one has to stop somewhere and define the boundary of impact, contours of liability, and exactness of liability. But it is still wise to consider and assess the impacts beyond the statutory confine and unresolved interests, for the common larger good.

Thankfully, today or anytime soon, most of the impacts of mega infrastructure can be defined and visualised based on historical observations and near-infinite scenario modelling, can be predicted, forecasted and modelled accurately with modern tools, and can be empirically constructed, or imagined beforehand by logic, wisdom and diverse consultation.

An inclusive city needs more than smart interventions!

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

Inclusiveness is not a function of smartness of the city. A city that is labelled intelligent still can't guarantee inclusion across spectrum of inhabitants or equity of service level across range of end users with varying needs.

Talking of smart citizen app for instance, we must deliberate who are the end users and whether digital benefits get distributed across citizens equitably or is it even accessible to all. Thinking of those homeless, those who can't read, those who don't own phone not to speak of smart phone, those who speak a different language, those whose needs are not listed in app, those who are too young or too old to use it, those who cannot access app due to health conditions, those who are not aware that such app exist, those who are running outdated app, those who do not have best data speed plan or access to internet itself and many others - a citizen app may mean different things to different inhabitants of city and meaningless to some.

Likewise in case of smart public infrastructure, how many actually access and uses public wifi other than tourists and few motivated others; who all actually have time and mindspace to switch to public wifi to save a miniscule amount of money and why will they risk malware attack and phishing if they have to use it only once in a while and when their personal telecom provider already gives them enough data and bandwidth. Again benefits reaches to only limited segment, actually those who are already empowered.

Like health equipment market which is skewed in a sense that those who are already fit tends to buy or use it more to be more fit, similarly E-governance for instance is more empowering to those who are already privileged in some sense or other, while the life of most of marginalized or at fringe or having specific or special needs may still remain unchanged by the noble initiatives like E-governance and public wifi network.

A sense of inclusion, belongingness and well being in a city has a different meaning altogether than solving city functionality through digital intervention or otherwise.

So how do we make a city which accommodates everyone's need - digital way or old analog way or with a parallel system of high tech and low tech intervention or on demand digital services or near-omnipresent services delivery or tailored door step governance and service delivery especially for those forgotten, those having limited means, those in dier needs, those marginalized and those at the fringe to make an equitable society.

WATER SUPPLY - Revisiting demand estimation approach

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

Flat assumption of Litre Per Capita Per Day (LPCD) water requirement as basis for residential water demand is most likely to give wrong estimate, error compounded by a)Fixed average household size considered b) multiple available choices for base year population like census, property tax records, existing municipal billing records c) randomised selection of population growth rate formula d) no consideration of water saving fixtures and appliances in the equation, e) no consideration of regional lifestyle peculiarity f) no consideration of water demand fluctuation over seasonal weather change cycle g) no consideration for emerging lifestyle changes

You will see why they pay little attention to such fundamental assumptions with this example. Have they revised per capita water requirement after covid Pandemic, hence the revised water demand at city level? Answer is "No", while no one failed to recommend that keep washing your hands frequently for instance. Imagine millions and millions of people suddenly started washing hands several times a day as a newly adopted lifestyle changes, some taking shower everytime they returned home from outside, but no thought given to accommodate likely changes in per capita water consumption due to same.

Further, are they going to revise Litre Per Capita Per Day number based on new lifestyle changes post Covid19 as citizens are likely to continue practicing good hygiene in future, adding more pressure on water demand. Likely answer is "No", but correct answer is that "they must revisit" LPCD number, including all other missed criteria as mentioned above.

Multi-criteria demand assessment and Agility are key to stay relevant when it comes to urban infrastructure planning.

CITY STORM WATER DRAINAGE SYSTEM -Revisiting fundamentals

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

SITUATION

No matter how well you plan Storm Water Drainage System, it often fails as it has so many missed variables, scores of design and operational dependencies, aging infrastructure and multitude of agencies to put blame on, later on.

TREND

Storm water and Urban Flood used to be two different things, but their boundaries have started to get blurred, as rainfall events are getting more unpredictable and severe due to climate change and as normal rainfall events have frequently started causing sticky urban floods that is not easily dissipated.

POSSIBLE MEANS TO DEAL WITH SITUATION

There are only couple of ways you can deal with storm water inundation and urban flood events, i.e. either move the city elsewhere OR tame the nature through uphill dams and artificial mega wetlands at outskirts OR brace the city with flood barriers OR capture and store part of runoff water allowing as much water to percolate if water table permits OR make way for water and allow storm water and floods to pass through city while assuring minimum impact and damage.

CHALLENGES

Temporal rainfall data of whatever time period used in modeling is primarily historic data, there is no consideration for future rainfall event modeling considering climate change, increasingly aggressive weather events being witnessed every passing year.

Historic Flood data doesn't consider cause and effect of flood due to slow or sometimes radical temporal change in built form and landscape of city.

Expanding cities, increasing paved areas, shrinking greens and disappearing urban waterbodies are changing the overall runoff coefficient of city converting normal rainfall event into disastrous situations and unmanaged events.

OPTIMAL SOLUTION

Instead or in addition to regular storm water network if you plan or redevelop your city as well as design buildings to allow periodic Inundation and water retention and absorption, that will be less destructive and less overwhelming then flash floods due to heavy downpour and in case of actual flood events.

It's important to keep reiterating that Multicriteria based assessment, design and scenario modeling is of utmost importance for planning any urban core infrastructure, be it SWD, SWM, Water Supply or Power Distribution.

Notion of good and bad Urban Streets -

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

Notion of good and bad Urban Streets -sometimes it's mote than skill or fault of urban planners, urban designers, transport planners, road engineers and landscape architects! 

Broadly, there are only limited known ways a street can be designed from junction to junction, there are only finite ways street facade can be articulated and modelled. (Possibly 80% of street design work machine can do on its own, by running algorithm in near future) 

Then, what is the differentiator between a good and a bad urban Street design and quality of street experience? 

Some variables-

Outcome of Transport modelling

Quality of Development Control Regulations 

Compactness of neighborhood

Permissible adjacent Landuse 

Permissible Floor Area Ratio (FAR) 

Economic status of Neighborhood

Generosity of Landscape elements

Quality and thoughtfulness of Street furniture

Age of city neighborhood

Attractiveness of neighborhood

Locational context of street

Image and significance of city

You can see there more than 50% of variables from above list which are not in control of planners and designers; variables that influences and sometimes decides the ultimate outcome of urban street design exercise, and shapes the notion of street quality and experience.

Legibility of City by design not by labels!

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

A case of many cities in developing countries and beyond.

Sense of getting lost and directionless in your own city can be a scary experience! More frequent is the phenomenon associated with planned cities compared to those towns and settlements which have evolved organically. Reason being several planned cities tend to get overwhelmingly repetitive in its modular spatial forms, sometimes making it unnerving during commute, while organically evolved cities usually boast multitude of visual cues and anchors to build a memorable streetscape.

Feeling disoriented or experiencing a sense of Déjà vu in a city is so common that people may repeatedly be unsure about correctness of path taken or exit chosen or flyover crossed on a daily basis on a routine path, as familiar as home-work-home.

Feeling of trapped in a maze is quite obvious and frequent a phenomenon in large residential neighbourhoods when it's sometimes difficult to orient yourself and finding an exit route seems a Herculean task, compounded by encountering random access gate closure.

It may take weeks or even months to actually being able to memorise or to get familiar with even frequented route, and then it's easy to forget again. It is clear that Legibility by labels or signage on its own and in all of it's collective forms, types and glory is certainly not being able to make a city legible in one go even for its regular citizens not to speak of visitors of city.

You cannot entirely rely on signage for navigation in a city, signage which are sometimes broken, sometimes vandalised, sometimes wrongly placed, sometimes unreadable by design, sometimes hidden from sight due to tree and plant foliage, sometimes owing to bad or no illumination. There are still only limited segment of citizens who actually or frequently are comfortable with or using or relying on GPS navigation maps and apps, and they who use such tools also encounter challenges like network connectivity, distracted driving.

Also acknowledging that a commuter driving a vehicle and continuously looking for signage and clues for direction is a potential threat on road due to lack of focus.

A careful attention and planning in terms of landscape variation and vegetation arrangement, landscape and urban design elements, lighting arrangements, architectural theme and design, facade articulation and zoning regulations, structural innovation etc. in combination with time tested and some better signage may possibly be the solution and attempt towards better legibility of a city!
