Safeguarding the Raleigh Park Fen

On the evening of 25 Jan 23, Stephen Parkinson (Chair of Friends of Raleigh Park) and I (your  local councillor) addressed the Vale Planning Committee about our concerns regarding the site at the top of Yarnells Hill, whose owners wanted to build 3 new dwellings.

At committee meetings, we only get 3 minutes to express ourselves, so I usually write to them ahead of time. This was no different. Here’s what my letter said.

Officers remind us that the NPPF says decisions must be made in accordance with the Development Plan, unless material considerations indicate otherwise. I contend that the high risk of irrevocable damage to the irreplaceable habitat adjoining the site is just such material consideration; the NPPF says irreplaceable sites like this must be safeguarded.

Vale is not in a situation where these three luxury homes are needed. We have currently over a 6 year supply of housing land. So our strategy for providing housing is working, and these extra windfall houses are not necessary to provide the housing numbers we have committed to.

The proposed mitigation must be monitored. Even if monitoring works and notes a failure of the mitigation, it will be after the fact and the harm will already be done. This is the nature of anything that requires monitoring to succeed.

Vale’s Countryside officer doesn’t support the application. Oxford City does not support this application.

This application has been set to come to committee three times. Each time, local people and concerned ecological professionals trying to preserve Raleigh Park’s ancient fen launch into action, presenting hard evidence to committee members to urge you to vote to refuse this development. For whatever reasons, planners have removed this application from the agenda at the last minute three times. Once it was to gain ‘independent’ paid consultants’ opinion regarding the ecological risk – this was when they hired a company, Aspect Ecology, to help them out (the same company that also provided evidence to government in support of HS2). Once it was during the planning meeting itself, when it was clear the agenda could not be completed (I don’t think officers included this instance in their report). Once, most recently, was when it was recognised that there had been a problem with consultation procedures. Each time, so many people’s hard work had gone into preparing arguments about why this application should be refused. Each time, the officers took away that evidence to bring back more arguments why this development should be allowed. Why is that? Is this council a culture where we are unable to revisit decisions in light of new evidence and come to a different conclusion? A large handful of ecological experts have all pointed out in detail what can go wrong, how the fen is endangered. It’s our duty to safeguard the irreplaceable habitat.

Please read Dr Parkinson’s assessment of the mitigations. He provides a summary of what several other ecologists have determined.

Over the years that I’ve been trying to protect the wildlife and natural resources up in this corner of Botley, we’ve seen about a dozen million pound homes built in this area, one site was turned from a single family home into multiple flats (Little Dene), and the whole of the development by Bovis of 136 homes went ahead. Badgers have been forced out of their habitats. Most recently a site just opposite was approved for two new huge houses. (That site is interesting; the decision to grant permission came early, in spite of officers telling me it was being considered alongside this one, due to the similarity in ecological concerns. It also adjoins Raleigh Park, but it is brownfield where the current site is green field.) Local wildlife now have only this small corner of Yarnells Hill available for foraging and shelter, adjacent to Green Belt, adjacent to an irreplaceable habitat in Raleigh Park.

But the main this is that this is a planning decision to be taken “on balance”. Does the benefit outweigh the risk of harm? A windfall of 3 houses vs damage to an irreplaceable habitat that it is our duty to protect. How can we rely on a planning condition that requires enforcement to protect what’s irreplaceable?

You can see the meeting and hear what everyone said on YouTube: https://www.youtube.com/watch?v=pkA4ZiPfIoA

Planning Committee voted unanimously to refuse the application. I’m very grateful to everyone who helped in this effort.

Support for the LM Pavilion Plans

Here is the response I submitted to the Vale consultation on the planning application V0696 for the Louis Memorial Pavilion.

I write as one of the Vale members for this area.

I fully support the plans presented here, with the inclusion of requests for changes from Sport England and any other statutory consultee. I fully support the parish council and the process they’ve followed to get to the point where they are applying for permission to do this development.

It is appropriate use of Green Belt land; although I don’t think the site is actually IN the Green Belt. It is a modernisation of recreational facilities in a community which has an historical underprovision. It is supported by the neighbourhood plan, which is nearing completion. It is supported by Vale’s leisure strategy which identified the pavilion and scout hut as in need of replacement.

I support the statements of the chairman, Cllr David Kay in his submission here, including the policies to which he refers and the wide consultations and community approvals throughout the process.

I’m pleased at the environmental responsibility shown by the PC in this design.

It will be a wonderful asset to the community and something everyone can point to with pride.

It will be up to the parish council (or any management group they set up) to work with potential users of this community facility to see what can be done to meet their needs. It isn’t a material planning consideration though.

20 Eynsham Rd application – I object

I’ve formally objected to (and called in to committee) the planning application P18/V2510/FUL for 6 flats at 20 Eynsham Rd.

Here’s what i said in my objection:

The plans don’t differ significantly from the previous ones.
The main problems are overdevelopment of the site, intensification of use, overlooking neighbours, so loss of privacy, especially with respect to 2 Tilbury Lane.

Applicant sought pre-application advice and was given it. Applicant seems to have ignored the advice given, essentially that intensification of this ‘relatively small site’ would not be acceptable. (In their application docs, applicants refer to it as a ‘relatively large site’. Didn’t listen to pre-app advice.) To meet the ‘no intensification of use’ criteria, we would expect an application for no more than 2 dwellings on this site to be acceptable in principle.

So applicant proposed to demolish two flats and build 6 flats, with 9 bedrooms and 6 parking spaces.

Vale’s design guide does not support car parks in front of flats.
Design Guide also has something to say about entrances to flats and flatted developments.
Unsafe access to and egress from parking.
Bins on Tilbury Lane. Would this be allowed?
Plans don’t reveal how many flat and parking spaces are disability accessible.
Over dominant relative to neighbouring sites.
Not in alignment with homes on Tilbury Lane
Six parking spaces for 9 bedrooms; not enough parking. No visitor or delivery parking. There is no parking allowed on Eynsham Rd or on the private Tilbury Lane.

This application is for a development that’s inappropriate on this site.
I have also called this application in to Planning Committee.

Licenses to harm badger setts and clans

I submitted a Freedom of Information (FOI) request to Natural England. I asked them to provide information about requests they’ve received from development sites in Vale for permission to damage, destroy, block or otherwise cause harm to or interfere with badger setts and clans.

Here is what I asked:

Dear Natural England,

Developers requesting planning permission are regularly told by our local planning authority that they need a license from Natural England to allow them damage, destroy, block or otherwise cause harm to or interfere with badger setts and clans.

Provide total number of such licenses in Vale of White Horse that were sought in the past 5 years. 
Provide a total of licenses that were granted in that time. 
Provide a list all such licenses that were refused in that time, and include enough information that we can understand the location and reasons for refusal.

If there are applications for such licenses that have another disposition other than refused or granted, please list them.

Regards, 
Cllr Debby Hallett

Natural England replied to me. They informed me that no licenses have been refused in the past 5 years. 

I think that perhaps this information calls for a reconsideration in how we use ‘harm to badgers’ as a reason to refuse in our objections to planning applications.

Earlier, I spoke with the environment officer at Vale, who explained to me that badgers are not endangered — there are lots of them. The act was put in place to prevent cruelty to badgers. That makes more understandable the frustration we experience when all development sites are granted license to damage or destroy setts or even clans. I don’t think it’s right, but now it is understandable. 

For more information on the Protection of Badgers Act 1992, see the RSPCA site here:  https://www.rspca.org.uk/adviceandwelfare/wildlife/inthewild/badgers/law

 

My comments for 54 Hurst Rise Road

I’ve submitted my comments for 54 Hurst Rise Rd.

I called in this application to committee in January 2017. So now I’ve submitted the list of issues that I think need a satisfactory condition or mitigation or change to the plans. You can see the doc in my dropbox folder here: https://www.dropbox.com/s/mtahf7n5499g7ie/54%20Hurst%20Rise%20Road%201%20July%202017%20Comments%20and%20ccancel%20call-in.pdf?dl=0

Site 2 – land north of Abingdon

The land for this development is mostly (or completely) in Sunningwell parish, which I represent. Around 900 houses are planned.

On Saturday 16th July, I attended the first of the public exhibitions hosted by the master planners, CEG. They won’t actually be building the houses. They plan the community and infrastructure and also develop a Design Code, which provides for the eventual developers the quality parameters for the developments in this community.

You can see the exhibition online at www.northabingdonconsultation.com

Car parking at the new West Way

Traffic and parking analysis is complicated, and a science and art that few of us can say we  understand. Have you read the traffic assessment submitted with this application? I admit I haven’t. But we have local experts here in Botley who have studied it very closely. And the rest of us still have common sense.

Currently, parking problems in Botley are growing. The problem mostly stems from the time park and ride charges increased. Commuters found free parking in Botley’s roads, very near bus stops or with easy access to the cycle paths into Oxford. Over the past 4 years or so, it’s become a real problem in some roads. The problem also comes from new developments where county has allowed fewer onsite parking spaces than would accommodate all the cars that come to live there. This is deliberate policy to encourage use of public transport, or cycle or feet. But it doesn’t always work in Botley. So roads are being parked up, especially down near West Way, where all the busses pass on their ways in and out of the city. Our first controlled parking zone has gone into Elms Road, so now residents have to pay for permits to park in their road.

Here’s what I’ve discovered, and I conclude there isn’t adequate on site parking for the uses they’ve planned.

  1. Currently, the three car parks are joined up so shoppers can circle until they bag a space. The planned car parks are discrete, separate, so in order to move from one car park to another, you must exit onto the streets and go to another car park.
  2. There are currently a total of 290 spaces in several places. This isn’t relevant to the argument, since everything in Botley will be different. I don’t understand why anyone is focused on current numbers of parking spaces.
  3. That said, the parking in front of Elms Parade won’t be changing, except that there will be NO exit at the easternmost end (toward the A34). Same number of spaces, same layout as now, except anyone entering from the west will need to somehow turn their car around to exit via the same access. We saw the difficulty in that plan when we visited on Monday.
  4. The new plan offers 321 spaces (para 7.81 of report). We learned on the site visit that all spaces are unallocated; it’s first come, first served. Approx 16 are for disabled parking. There are 2 or 3 with chargers. This number includes the existing spaces at the front of Elms Parade. (Other counts from the plans show 317 spaces, after 16 May 16 amendments. I’ve asked officers for a true count, but haven’t heard yet.)

So I, as a reasonable adult non-parking-expert, as are we all, consider the uses of the new West Way, and how many people will bring how many cars.

  1. Staff: Predictions are for 248 FTEs. What percentage would be expected to drive and park? In the 2011 census 70% of people working in North Hinksey and Wytham drove to work. This is lower than the Vale average of 72%. Of course, 248 FTEs could be 500 or more part timers. This site is handy to busses, so probably fewer. Is a reasonable guess about 150?
  2. Residents: We learned in the viability report that there will be 1 parking permit per 2-3 bedroom flat, and .5 per 1 bed flat, and an additional 75 permits to be sold. In a previous report I calculated 188 spaces to go with the residential units. (Remember where I said to remember this figure for later?) This is a larger number than the one used in the Transport Analysis, which predicted 112 spaces for flats.
  3. Hotel: There are 123 rooms. Remember there is no allocated parking, so all spaces are first come first serve. Would a reasonable person guess about 50 spaces?
  4. So staff parking, residents’ permits, and hotel takes about 388 spaces, or more than is available, so they spill over into neighbouring streets.

We learned on the site visit that all the retail units in Block A are intended to be restaurants. How many parking spaces are needed to support them?

Trip rates assume lots of shoppers. Where will they park? Where will users of community centre, library and church halls park?

I’ll go out on a limb and predict some students will bring cars to the area, especially since we are so far away from Oxford’s universities.

Oxfordshire County Council commented “The highway authority considers that it is unlikely that residents can be prevented from owning cars, and unplanned demand for parking will need to be accommodated elsewhere.”

How can this be considered to be anywhere near enough parking for this shopping centre?

Affordabile housing and viability at West Way

Right now, today, 10 June 2016, there are five 2 bedroom flats for sale in Botley. Their prices are:

  • £350,000
  • £325,000
  • £280,000
  • £250,000
  • £225,000

That’s an average of £286,000. For a 2 BR flat. We need affordable houses here.

I found ten 2 bedroom flats for let, for an average monthly rental of £1485. People on ordinary wages can’t afford that sort of rent. Affordable housing is arguably Vale’s most urgent need.

This application provides 140 residential units. None will be affordable, by the developers own admission (in the viability report, see links below).

The developers have offered to make 10% of net new houses (13 houses) starter homes, at 80% of market value.  What does that mean in terms of real affordability? The new government programme caps starter homes at £250,000. Since Mace are offering only 1 bed flats as starter homes, I assume the bigger ones would be over the cap. So we’ll have 13 starter homes, 1 bed flats, for sale for about £250,000. That hints at very high priced flats, compared to our current average. (Combining some maths and a bit of reasoning brings me to the conclusion that the 1 BR flat prices start at £312,500. That’s the market price where 80% is £250,000.) Nothing wrong with that. We live in a capitalist world.

Vale’s current policy is that 40% of developments this size must be affordable homes, with a mix of 75% social housing and 25% shared ownership. That would bring 56 houses into availability for people who qualify, and 42 of those would be new social housing for the families who need them. But the developers have said that in order for this project to be economically viable, they can’t afford to provide any affordable homes at all.

I have three main points about this:

  1. The sales contract has some requirements the developer must meet, and the Vale has policies about affordable housing provision, which both cost money.
  2. Vale lacks experience in accepting financial contributions in lieu of affordable housing. We’re losing out from naïveté and lack of planning policy.
  3. Mace admit their scheme is so close to being economically unviable that they are unable to provide any affordable housing, as evidenced in their viability assessment report.

First, there are some sales contract conditions, and there is Vale policy.

  • The buyer had to re-provide the Baptist Church, community hall, and library. Presumably these would not be profitable to the developer.
  • For some reason Vale also required buyers to build a hotel, a multiplex cinema, and a very large supermarket. But the supermarket size was drastically reduced, and the hotel was made slightly larger in recent modifications to the sales contract. Developers dropped the cinema.
  • Planning permission is required for all of this, plus whatever else the developer wants to build on the land.
  • These requirements are part of the sales deal that was negotiated back in 2012 for a certain sales price. It was all out in the open for the buyer.

Vale policy requires:

  • If houses are to be built, then 40% of them must be ‘affordable’ (mostly social housing but partly shared-ownership).
  • This is all known up front, in advance, and something the developer should have planned for.

Para 7.29 of officers report says, “It [applicant’s viability report] identifies the land assembly costs of this proposal are high due to the value of existing uses and indicates the developer’s return will be below competitive benchmark rates. As a result the viability appraisal shows that the scheme is unable to be delivered is affordable housing is provided in accordance with policy H17.” I translate that as, “ It will cost so much to get title to this land, because it’s a valuable shopping and commerce centre, that we won’t make enough profit if we build the plan we have and also have to provide affordable housing.” I think that’s unacceptable. I think if the plan can’t deliver what it needs to, then it need to be reconsidered. It’s not an economically sustainable plan. It should be refused.

Second, Vale lacks experience in accepting financial contributions in lieu of affordable housing.

Sometimes new developments are too small to realistically provide 40% affordable housing. Picture a development of two houses, for example. Vale can negotiate a financial contribution in lieu, to be used to provide affordable houses elsewhere. I don’t know how often Vale actually do that, but they’re allowed to.

Student housing is typically built on land that could accommodate affordable housing, such as in this case. Vale doesn’t have any experience in planning for student accommodation and especially how provision of student accommodation affects the availability of affordable homes.

But Oxford city does have this expertise in both of these situations, and they have policies in place to protect the provision of adequate affordable housing.

Oxford has policies that cover situations when the developer cannot provide affordable housing on site. Usually this has to do with small sites, where it would be hard to provide the required percentage of affordable when you are building two houses. City will accept money in lieu, as a contribution to affordable housing elsewhere.

Oxford also has policies for ensuring land used to build student accommodation doesn’t prevent affordable homes being built in the area.

Here’s how Oxford’s policies calculate the amount due for contribution to affordable housing:

  1. Market houses: 15% of total sale value is due as a contribution to affordable homes elsewhere.
  2. Student accommodation: £140 per sq m as contribution to affordable housing.
  3. This current planning application: 140 1-2-3 bedroom flats. If we use the average prices in Botley, the average 2 bed flat costs £286,000. If the developer sells 140 flats at £286,000 each, that’s £40,040,000 total sales price. Fifteen percent of that sale value would be £6,006,000. (This is just an average. The mix of housing sizes means the real amounts would be different.)
  4. This current planning application: there are 10,550.5 sq m of student accommodation. Oxford charge £140 per sq m. So if this development were in Oxford, the contribution to affordable housing would be £1,477,070.
  5. The total amount expected as a contribution to affordable housing elsewhere in the area, if this were a few hundred meters to the east (in Oxford): £7,483,070
  6. See para 7.31 where the officer’s report discusses the commuted sum of £2,000,000 currently being negotiated. It’s also been in the news this week. See the article here.

Third, Mace admit their scheme is so close to being economically unviable that they are unable to provide any affordable housing, as evidenced in their viability assessment report.

The developer’s viability report has only come to light as a result of a Freedom of Information request. I don’t see that this has been published on the Vale’s website. I don’t know how planning committee members were expected to see it. I guess you weren’t. But you can see the (redacted to remove commercially sensitive information) docs released under FOI here: Viability Report

In the report, Mace claim that their costs are so high, and this project has so much risk, that they expect low to no profit. Even when their income on all aspects is at the highest end of what could be expected, if they were to provide any affordable housing, it would make this project economically unviable. I’m not making this up. Go have a read of the main report via that link just above.

In this report, they tell us:

  1. 140 residential. 55 1bed, 80 2bed, 5 3bed.
  2. 22 retail units
  3. 261 student and academic rooms
  4. 123 hotel rooms
  5. 377 car parking spaces (Numbers elsewhere are different. See officers report para 7.81 says there are 321 spaces. Counting spaces shown on the plans gives 317. So I’m not sure what’s real.)
  6. Parking: all 2&3 bed flat get one space. All 1 BR flats get .5 spaces. There are 55 1bed flats, so 28 spaces. 85 2-3 bed flats, so 85 spaces. 75 other spaces will be sold. Total parking spaces for residential units = 188 parking spaces. (Keep that in mind for later.)
  7. The retail in Block A is expected to be all restaurants. Block C, D and E are to be more traditional retail operators, national chains who will pay higher rents. The retail rental income is expected to be ‘significantly in excess’ of current.
  8. Hotel had no tenant lined up as of the March 2016 date on this report. But lease or sale was expected to be at the upper end of what’s achievable in Oxford.
  9. Student accommodation rents are expected to be at the upper end of what’s achievable for Oxford.
  10. Library is a D1 community use. Rent will be at the current level. If county decides to close libraries, developers claim it ’would be difficult to secure a use-compliant occupier at a similar rent level’. I interpret this to mean D1 are low rents, but OCC is at the higher end of the D1 range.
  11. Business space in the new centre is far away from other offices in Botley so they say they may struggle to find occupiers.
  12. Viability report hasn’t allowed for the s106 contributions amounts (about £750,000 I think.)
  13. Bottom line: developer profit is ‘significantly below a level which a prudent developer should or could accept for taking on the risk of a scheme of this complexity and scale.’
  14. Here are local expert opinions:
    1. Developers expect income at the high end of what’s achievable for Oxford, but Botley isn’t the same as Oxford.
    2. Expected retail income is at high end, so probably pricing our small local independent traders. The higher rent-paying national chains would probably rather be in the new Westgate than in Botley.
    3. The student accommodation examples they quote aren’t comparable to this plan for Botley. Examples are cluster flats, couples flats, not the same as the rooms coming forward here. To be honest, if you hear from experts in the Oxford University student accommodation realm, the developers here are comparing apples and oranges. I don’t know enough about how Oxford University works to be able to understand it, let alone to argue it. I rely on experts. Look for statements by Professor Hilary Priestley, who has decades of experience with student accommodation at OU.
    4. High rents in student accommodation seem to ignore the (un-)desirability of the location. Who would come to Botley to pay these high rents? Their own new student accommodation management company, CRM, say on their website that the main social centre for their students are the Oxford colleges’ bars, and the Oxford Brookes Student Union. Those aren’t in Botley.
    5. One of our local people summarised it well, I think: ‘So the policy has to be waived to enable a financially unsustainable development to gain planning approval.  Surely, that is impossible to justify. I know there is an argument that the developer is in business to take some risk, but when they admit, even with top end valuations, that their proposal does not make economic sense, surely the only conclusion is to say no to planning approval.’
    6. Indeed.

Planning Applications – how they’re determined currently

Residents who oppose what they see as inappropriate development are feeling frustrated at failed attempts to see planning applications refused. It used to be the principle that, ‘This isn’t good enough to approve. ” Now the rule of thumb has changed to, ‘This isn’t bad enough to refuse.’ That’ change in perspective has come along since the National Planning Policy Framework (NPPF) was adopted, which states a presumption in favour of sustainable development.

Right now the Vale of White Horse has no adopted Local Plan, and therefore Vale cannot demonstrate a 5 year land supply for house building. Once the Local Plan is adopted, we will have both of those things. Until we have both those things, refusing a planning application is difficult, but not impossible. Until we have both those things, our local policies hold less weight, and the NPPF is the main policy.

In his Decision Report for 54-56 Hurst Rise Road of November 2015, the Inspector considered the applicant’s appeals against refusal. He said:

Background and Main Issues

3. The Council accept that they cannot demonstrate sites sufficient for five years worth of housing against their housing requirements as they are advised to do in the National Planning Policy Framework (the Framework). Paragraph 49 of the Framework advises that housing applications, as this is, should be considered in the context of the presumption in favour of sustainable development and that relevant policies for the supply of housing should not be considered up to date if the Council cannot demonstrate a five year supply of deliverable housing sites. The presumption in favour of sustainable development is set out at paragraph 14 of the Framework and includes advice that where relevant policies are out of date planning permission should be granted unless the adverse impact of doing so would significantly and demonstrably outweigh the benefits of the scheme. Given the need to boost significantly the supply of housing and that the site is located within the built up area of Botley, an area where new housing will be permitted subject to its impact on character and facilities important to the local community (policy H10 of the Vale of White Horse Local Plan 2011, July 2006 (LP)), there is strong support for the principle of developing the site for housing.

4. However, the presumption in favour of sustainable development seeks to achieve economic, social and environmental gains and positive improvements to the built and natural environment. I must therefore consider the detailed aspects of the proposals against these aims to determine whether the benefits of the development proposals would be significantly and demonstrably outweighed by any adverse impacts that may arise from granting permission such that the proposals would not amount to sustainable development. (my emphsis)

So, wherever it can be convincingly demonstrated that the harm from the proposed development significantly and demonstrably outweighs the benefits, the application can be refused. 

There’s the strategy. That’s the trick.

My Comments for 56 Hurst Rise Road

I just submitted my comments for the planning application at 56 Hurst Rise Rd. Here’s what I said:

I write as the local Vale of White horse council member for this area.

I’ve studied the plans and docs available. I note that the Tree Officer would like to see a current tree survey and some cross section drawings.

It’s actually quite difficult to picture the scale of what’s proposed, because there are no drawings showing the context of the proposed houses in the street scene, nor any drawing to show us how the proposed houses fit into the context of the site and with its neighbours. That seems a serious enough shortcoming.

Applicant claims the inspector approves of this plan for detached 4BR houses; how can that be? Could the officer please clarify this for residents and for me?

I also notice that tree reports (and other data?) come from old studies submitted with applications that were refused. I think there’s a reasonable chance that since the applications were refused on larger grounds, the fact there is no objection on these specific grounds named in the design statement are irrelevant and do not assume there would have been no objection had the applications been considered further. By that I mean, if the proposals are determined to be much too big and harmful to the character of the area, enough to warrant refusal, would detail of tree surveys be closely studied? Maybe so, but I don’t know. Surely a new application on a site different to the refused applications deserves properly current accompanying reports.

This is part of the lower density area of Cumnor Hill as defined in Vale’s Design Guide. In checking the Design Guide for lower density areas, there’s a useful checklist on page 142. Is there evidence that these issues have been considered in this proposal? I would have expected pre-application meetings to cover all these issues.

It does appear this development would be out of keeping with the local area. It’s a large semi-detached structure, built right up to the property boundaries, without garages or room to turn cars to be able to exit in a forward facing direction.

Does the parking scheme comply with section 4,3 of the design guide? It appears the four parking spaces, intended for 8 bedrooms plus visitors and delivery vehicles, hasn’t been well thought out. We expect that the front gardens are not parking dominated (see principle DG82).

Please can the officer address issues of density and how this proposal fits into that aspect of the character of the area.

Please can the officer clarify the private amenity space for each house. With 4 bedrooms, each house should have 100 sq m of private outdoor space.
