“The former ‘British Sugar’ (sugar beet factory) site, Sproughton (Ipswich fringe) is allocated for retention in employment related use(s). Proposals for redevelopment or re-use of the site must be approached on a comprehensive basis, with full regard to the future of the entire site. A range of land uses will be required, as appropriate to the different parts of the site …”
“In towns, housing developments will be granted planning permission, provided they have no material adverse effects on residential amenity, the environment or traffic generation, or result in the loss of a viable employment site.”
“4.57 The District Council considers that in an area under pressure for residential development and where appropriate new employment sites in villages and towns are hard to find, there is as a general rule, a pressing need to protect existing employment, sites and premises. 4.58 Many proposals for re-using or redeveloping employment sites and premises come forward for determination. In such instances, in order to demonstrate that other forms of employment use have been fully explored, documentary evidence will be required to demonstrate that a proper and sustained marketing campaign, at current market value, for either continued or alternative employment purposes has been undertaken. Important factors in evaluating the appropriateness of such a campaign will be the length of time it has been pursued and the prevailing market conditions. Examination of documentation of enquiries and responses will be expected. 4.59 The marketing campaign will have to be agreed between the determining authority and applicant(s) before it begins. This will include the following: • length of campaign; • asking price; • sales particulars; and • number, frequency and source of advertisements. 4.60 In agreeing the asking price, an independent valuation may be required, that the applicant will normally be expected to fund. The District Council will apply policy EM 24 to all proposals affecting land, sites or premises in, formerly in, or allocated for employment use. This will be supported by supplementary planning guidance to help people with their planning applications. Proposals will be expected to keep to this guidance.”
“Planning applications to redevelop or use existing or vacant employment land, sites and premises for non-employment purposes, will only be permitted if the applicant can demonstrate that their retention for an appropriate employment use has been fully explored. This may be undertaken in one of the two following ways: 1. by an agreed and sustained marketing campaign, undertaken at a realistic asking price; or 2. where agreed in advance, the applicant can demonstrate that the land, site or premises are inherently unsuitable or not viable for all forms of employment related use.”
“The use of the approach listed at 2. in policy EM 24 will only be considered acceptable when agreed in advance by the determining authority and the applicant. This approach will require the applicant to employ appropriate commercial expertise to demonstrate that the land, site or premises in question are inherently unsuitable or not viable for all conventional forms of employment related use …”
“32. … the Secretary of State concludes that the proposed housing provision would significantly contribute to the region’s housing requirement, and the affordable housing provision would help it meet an identified need. Nevertheless, the appeal proposal for mixed uses is not in conformity with the allocation of the site for employment uses in the recently adopted local plan, and the Secretary of State considers that the employment needs of the region as identified in the development plan and the emerging [regional spatial strategy] should not be dismissed lightly. In particular, she considers that no decision to develop this site other than in accordance with the development plan should be taken in advance of serious attempts to comply with the policies of local plan policy EM 24 and should be based on a comprehensive assessment of the employment land needs of the sub-region and the [Ipswich area]. 33. Like the inspector, the Secretary of State had found shortcomings in the evidence of both the main parties on the viability of this site and she considers that it has not yet been demonstrated conclusively that the employment allocation under local plan policy EM 04 is no longer appropriate. She therefore concludes that, at this point in time, there is insufficient evidence to justify determining this appeal other than in accordance with the development plan. However, she takes the view that if, after a reasonable period has elapsed to allow the effective marketing of the site in accordance with the local plan provisions, the future development of the site remains uncertain, it would then be appropriate to review the local plan allocation, preferably as part of a generic and fully informed exercise.” (Emphasis supplied)
