Ref: 23/00606/B Applicant: Mr Mark Pearce
Proposal: Appeal against the approval for construction of 3 garages to plots 4 and 5 and foul drainage connection of previously approved and commenced development PA 20/00787/B and PA 19/01324/B
Address: Field 314758 And 312909 Main Road St Johns Isle Of Man
The boundary as represented on plan 0725/PL103 Rev C12B that separates both plots 1& 2 from Mr & Mrs Davies's approved plot (plan 24/00276/REM ) is incorrect.
The legal document that establishes the boundary was requested by the planning officer to substantiate access for 24/00276/REM . As drawn 0725/PL103 Rev C12B has our garage partially on plot 1.
The applicant has had sufficient time and notice to correct the plan. There is also a clear gap between the access to plots 1&2 and Mr & Mrs Davies's private access lane to their plot which was not on earlier site plans which may also compromise their development. We consider this prejudices our approved application and is contrary to: Part (k) of GP2.
Reserved Matters application to PA 21/00365/A for the erection of a dwelling and garage with associated landscaping, addressing siting, landscaping, drainage, design, internal layout and external appearance.
The applicants planning approval is: PA 24/00276/REM Part Of Field 312909 Balladoyne Farm Main Road St Johns Isle Of Man
Statement by Ravenhill Resources Ltd the applicant: This issue is a boundary issue which is not a planning issue. The appeal should not have been accepted on these grounds. I have attached a plan by McGarrigle Architects Drawing no. 1853/02/P03 showing the sewer connection which is also the same as our connection on PA 23/00606/B which is agreed between the parties.

I also attach the engineers drainage calculations and scheme entitled AXO360-NOT-1 Balladoyne Drainage which was approved by the MUA as part of this application.
The boundary as drawn on the scheme encompasses the works being carried out and therefore complies with the application.
The ownership boundary is different albeit Ravenhill Resources Ltd have a right of access across part of the field to access the sewer as shown on the drawings.
The fence to Mr & Mrs Davies’ plot is now the ownership boundary but when the original planning application was submitted it was not. This is why there is a slight difference in red line boundaries. It does not affect the application and encompasses the work which it is required to do.
Mr and Mrs Davies land was excluded from the various planning applications made by Ravenhill Resources Ltd and this does not affect the houses that are now underway.
This appeal is holding up the occupation of Plot 4 and 2 which are both near completion but cannot be completed or connected to the sewer whilst this appeal is ongoing.

Axis Consulting Engineers Ltd have been requested to appraise the proposed foul drainage system at the Balladoyne development in St Johns, where 6 dwellings are being constructed.
The foul system connects into an existing Manx Utilities foul sewer system (at Manhole 9701), with invert level 41.01mAOD. The proposed system is intended for adoption.
Levels at the site are relatively flat and the distances to the existing sewer preclude a 1:60 fall across all runs on the new system, without significantly raising the proposed plots.
Figure 1 – extract from developer’s plans showing proposed development.
Manx Sewers for Adoption [1] states the following:
Other relevant standards and code of practises are:
Calculations have been undertaken in line with BS EN 752-4 and in accordance with Spons Urban Drainage Second Edition [4], flow rates have been calculated in accordance with discharge units [2] with associated probability factors.

In summary where 4 or more houses are served calculations can justify a 1:80 fall at design flow. Where there is a lower flow than this it is recommended that a 1:60 fall should be implemented.
(All adoptable runs taken as 150mm minimum)
It should be noted that this is based on design flow rather than one third design flows (MSfA) and therefore may occur less frequently, although the proposed falls would be acceptable under Sewers for Adoption 7th edition with a smaller pipe diameter (higher frictional losses), based on empirical evidence.
Based on the calculations it is proposed that runs 1.8, 1.7, 1.6, 1.5 & 1.4 could be laid at 1:80 falls whilst achieving selfcleansing velocities at design flows.
Consideration of floor levels in Plots 5 & 6 is required, and/or areas of private drainage may require concrete encasement to meet required levels – the developer has advised it is possible to accommodate proposed drainage levels. It is recommended that all private drainage and laterals are set to suitable falls to ensure a self-cleansing regime.
Adequate construction controls should be undertaken to ensure falls are maintained and there are no shallow areas or areas of settlement that may subsequently impact on the efficiency of the proposed drainage system.
