Officer’s Report
THIS APPLICATION IS REFERRED TO COMMITTEE AT THE REQUEST OF THE HEAD OF DEVELOPMENT MANAGEMENT
0.0 PRE-AMBLE 0.1 Following the officers presentation to committee on the 21/02/22, the applicants submitted amended plans at the meeting to satisfy the commissioners concerns that included; the widening of the ramp from 2.5m to 3m, the utilisation of glass walling in lieu of interim pillars; and the ratio of 50/50 split for glazing to walling.
0.2 The chair requested the matter to be deferred until the next committee of the 14th March to allow all parties to consider the amended drawings as some members were online and not able to view those plans. The amended plans listed below were uploaded onto the digital planning file following the committee presentation for all parties / stakeholders to view.
0.3 The amended drawing received on the 21/02/22 are referenced; 102_C - Details of Proposed works 101_B - Site Plan 100_B - Location Plan
0.4 The owner/occupier of 2 Glen View, South Cape, Laxey made further comment (01.03.22), which raises the concerns about the points as summarised below:
==== PAGE 3 ====
21/01102/B Page 3 of 9
0.5 In response to the above, the concerns noted, although some matters not agreed with. The recommendation amended to add condition re: glass and wildlife (C4). In addition to the above condition, the plans to be referenced on the decision notice have been updated. The report below is otherwise unchanged.
1.0 THE SITE 1.1 The application site identified in red is the section of river that starts at the new bridge opposite the shore hotel and runs upstream for 60m length to the south of the river and parallel with the pub car park. The applicant notes; "Sections of the existing retaining walls are constructed of mixed materials. Several sections of the walls have been identified as needing urgent attention in recent assessments carried out by the Department". At present there is no walling adjacent to the shore hotel and is only a post and wire with
1.2 This application is an extension of previous permission for flood defences along Laxey River that started at the woollen mills and extends downstream. Further details of previous approved applications are noted in the planning history below.
1.3 The previous planning permissions are currently in different stages of fruition as certain works to the river are only allowed outside of the spawning season.
2.0 THE PROPOSAL 2.1 Proposed is are a series of flood protection measures to the area adjacent to the shore hotel for a length of 60m. This will broadly see the strengthening of the existing river wall and construction of a glazed area (1.1m high from existing ground level) along the river edge that will be integral to the flood protection along this side of the river. Part of the existing concrete tow to the eastern part of the river wall is to remain as is.
2.2 To the west of the site adjacent to the carpark, is an earth bund that would provide additional flood protection. The agent notes; "the entire point of the earth bund is to provide flood protection to the Shore Hotel and car park area in the event of extreme river levels overtopping the river bank upstream of the new wall. This area would act as a temporary attenuation area until the river levels subsided and would then drain back into the river. I would also point out that the possibility of this actually happening is extremely unlikely. The original concrete ramp has been softened to become integral with the earth bund but still has a concrete surface to allow vehicle access".
3.0 PLANNING POLICY 3.1 In terms of local plan policy, the application site is within an area designated as 'predominately residential' on Map 7 in the Area Plan for the East December 2020.
The Area Plan for the East Written Statement 3.2 Within the accompanying written statement, Glen Road Laxey does not generally feature, Laxey River is noted amongst other rivers for populations of spawning salmon and sea- trout. With regard to flooding and erosion in section 5.20.1 refers to the 2016 National Strategy on Sea Defences and Coastal Erosion Evidence report which identified areas at risk of fluvial, surface water and coastal flooding within this, Laxey, amongst other areas was identified "as being at high risk both now and in the future and require urgent consideration, further investigation and potential intervention to reduce the evident risk". Section 5.20.2 notes the impact of flooding, weather and the flood risk when allocating land for future development and "flood risk acting as a critical constraint in the Site Assessment Framework used to assess proposed sites". Section 5.20.3 identifies that Flood risk maps have been produced by the MUA and their data used to identify flood risk areas.
3.3 Natural Environment Recommendation 3
==== PAGE 4 ====
21/01102/B Page 4 of 9
The Department supports further consideration and investigation of the impacts of coastal, fluvial and surface water flooding and coastal erosion on key economic, infrastructure, environmental and social receptors. The ongoing work of the Flooding Advisory Group is recognised as part of this, as well as the findings and recommendations set out in the Laxey Flood Independent Review Report. The following, including the areas of Douglas (comprising Douglas Bay, Douglas Harbour, Glass/Douglas/Dhoo/Middle River Confluence, River Glass and Upper Dhoo) and Laxey, are all identified as being at high risk both now and in the future.
3.4 With regard to the Historic Built environment, in section 6.8 talks about safeguarding the local character local character, particularly those features which fundamentally define the historic built environment in the East. Part of section 6.8.3 provides helpful guidance; "Existing and new development can exist side by side, even with some visual differences presented by old and new building styles. New development should not seek to mimic existing development but be of its own time".
3.5 Urban Environment Proposal 3 Development proposals must make a positive contribution to local character and distinctiveness. Traditional or contemporary approaches may be appropriate, depending upon the nature of the proposal and the context of the surrounding area.
3.6 With regard to Tourism in the east in section 10.2.1, only the Laxey wheel and the Great Laxey Mines Railway are noted.
Conservation Area Designation 3.7 The length of the application site is also identified as being within the Laxey Conservation Area 1990.
Strategic Plan 2016 3.8 Within the adopted Isle of Man Strategic Plan 2016, the following policies are considered to be relevant in the determination of this application:
3.9 Strategic Policy 4 Proposals for development must: (a) Protect or enhance the fabric and setting of Ancient Monuments, Registered Buildings(1), Conservation Areas(2) , buildings and structures within National Heritage Areas and sites of archaeological interest; (b) protect or enhance the landscape quality and nature conservation value of urban as well as rural areas but especially in respect to development adjacent to Areas of Special Scientific Interest and other designations; and (c) not cause or lead to unacceptable environmental pollution or disturbance.

4.0 PLANNING HISTORY 4.1 It is pertinent to consider previous approved planning applications to Laxey River and flood defences:
4.2 20/01385/B - Construction of reinforced concrete wall with stone cladding for the purpose of providing flood protection. This Section of wall ran from the Laxey Woollen Mill to No.4 Victoria Terrace.
4.3 21/00298/B - Construction of flood protection walls. This section of walling runs from rear of 4 Victoria Terrace and extends down the river for approx. 240m to the rear of Figtree cottage.
4.4 21/00300/B - Alterations to substructure of existing weir and re-grading of river channel incorporating a rock ramp to control flow and stabilisation of existing river banks. This section was to the north of Victoria Terrace on Glen Road Laxey.
4.5 21/00875/B - Construction of reinforced concrete wall with stone cladding, blockwork rendered masonry walls and soil embankments for the purpose of providing flood protection. 'Amulree' and Adjacent Car Park, Tennis And Basketball Courts, Glen Road. Laxey. APPROVED.
5.0 REPRESENTATIONS (in brief, full statements can be read online) STATUTORY CONSULATIONS 5.1 Garff Parish Commissioners commented (12/10/21 & 01/11/21) on the proposals visual impact and appropriateness for the Conservation Area, Following liaison with the Commissioners, they seek to approve the application subject to a condition in place that details the final design of the wall and agreed prior to implementation.
5.2 Highways Services have commented (06/10/21) and do not object.
==== PAGE 6 ====
21/01102/B Page 6 of 9
5.3 DEFA Inland Fisheries have commented (14/10/21) any works to the watercourse bank and channel are restricted to a period July to September (inclusive) to avoid spawning fish. Also, the works will need to be carried out in accordance with an agreed method statement, in advance of works starting to minimise disturbance to fish within the river.
5.4 DEFA Ecosystem policy officer commented (20/10/21) on the Statement of Case, and the commissioned Ecological Impact Assessment, that has been discussed with the applicant (DOI). They do not believe an EIA is required for these works and would be in line with the method statements agreed with Inland fisheries.
5.5 DoI Flood risk management (04/10/21) Do not oppose.
NEIGHBOURING COMMENTS 5.5 2 Glen View, South Cape commented (31/10/21) on the commissioners comments, the appropriateness of concrete material is not fitting for a Conservation Area that is dominated by Manx Stone, Unscaled drawings in the statement of case (full scaled plans are available online) Designers have ignored the west of the site that will continue to flood by the construction of the bund and ramp.
6.0 ASSESSMENT 6.1 The fundamental issues to consider in the assessment of this planning application are;
(i) Justification for the works (EP7a, b ;) (ii) Impact on the neighbouring properties (GP2g; EP22) (iii) Any adverse harm to the watercourse or (EP7c, d; GP2d) (iv) Visual impact on the wider streetscene and Laxey Conservation Area (SP4; EP35; GP2b&c)
6.2 Justification The starting point is the recommendations that were derived from the Arup report which has enabled JBA consulting to carry out surface water modelling and identify flood risk reduction opportunities possible within the Laxey Area. Of the 50 options for river, tidal and surface water flood risk alleviation, one of the options and the subject of this application is a new retaining wall between the Laxey River and Glen Road. This is further emphasised in the latest report (Laxey Flood Alleviation Scheme Feasibility Study 2020) at paragraph 6.1 titled; Long list of options - Fluvial and tidal referenced; (noted below in 6.3) This is also featured in paragraph 6.2.2 MER Weir and Glen Road Walls on page 35/36 where the table and pictogram shows the location of the works".
6.3 There is a wider government initiative to progress mitigating measures to offset flooding under the 'Programme for Government for a Sustainable Island' where it says; " Continue to invest in sea defences and in reducing flooding and coastal erosion risks for those areas identified as high risk in our national strategy". Laxey River has been identified as being high risk and the requirement for these works has been identified within the latest report from JBA consulting and previous studies, as noted above, which has been sufficiently documented and justified. Of all the works shortlisted, and the subject of this application, are seen as one of the most fundamental aspects to implement the necessary safeguards. As such the department is satisfied there is sufficient need for the principle of the works and as no evidence or conflicting professional hydrological reports to the contrary are published, the application would be in accordance with Environment Policy 7 (a,b).
6.4 Neighbours The scope of works that would offer residents greater protection from flooding would be considered to be relatively non-contentious in the respect to the visual impacts on the neighbouring properties and would not be considered to be detrimental to their amenity. The immediate residents of Glen Road have not commented on the application, possibly as they are
==== PAGE 7 ====
21/01102/B Page 7 of 9
to benefit the most from the works and this would offer the added protection from flooding over the years safeguarding their properties. This aspect would be read in accordance with GP2g & EP22.
6.5 Watercourse The scope of works will see this part of the river boundary wall being transformed as previously noted in section 2.0 of this report. Importantly the comments from the inland fisheries are helpful and the applicant and their appointed contractors would be required to liaise with them for the production of a full method statement/ risk assessment of all the activities involved for works to replace the walling prior to the works commencing on site. On balance, the proposed scale of the works whilst would be initially invasive to this section of river and the boundary wall can be undertaken in a safe and appropriate manner to protect the quality of the local environment and would not adversely harm the water course, and would be compliant with GP2d and EP7c,d. This aspect can be controlled through an appropriately worded conditioned to ensure adequate safeguards are in place during the construction works and also bird nesting boxes for grey wagtails are included in the scheme as per the comments from the Eco-systems policy officer.
6.6 Visual Impact The proposed replacement wall is partially visible from the side of the river where there is a public footpath No.415 which runs from the Shore Hotel to the Commissioners offices (approx. 1km in length). Equally from the other side of the river, along glen road the glazed wall will be visible against the backdrop of the shore hotel. Whilst the proposed wall would be visible and the drawings indicate that stone cladding is to be used for the majority of its length, this is considered to give a uniform appearance and is welcomed and can be conditioned to ensure its retention is retained in perpetuity. This is the same method of cladding utilised on previous schemes as noted in the planning history.
6.7 The proposed appearance of the glass wall with stone cladding would be sympathetic to the surroundings as too would the creation of an earth mound to the west of the site and would be appropriate for the area without being detrimental to the wider Conservation Area. Any visual impact or loss of historic walling that is being replaced or bolstered is deemed to be minimal with any harm being outweighed by the benefits of flood protection to the existing dwellings and their residents and is sufficiently justified as noted above. This aspect would comply with Sp4, EP35 and GP2b&c.
7.0 CONCLUSION 7.1 The application has been considered and on balance would be appropriate for the area and would not harm the use and enjoyment of neighbouring properties or considered to harm the watercourse or that of the Laxey Conservation area has been designed to comply with Strategic Policy 4, General Policy 2 and Environment Policy 7, 22 and 35 of the Strategic Plan 2016, and is recommended for approval.
