Northampton Borough Council's local plan part two sets out detailed planning policies for the borough up to 2029, including new site allocations and housing delivery trajectories, and was approved for consultation at a meeting of the council’s cabinet last week.
As part of the West Northamptonshire joint core strategy, the council has previously committed to the provision of 18,870 new homes between 2011 and 2029 but is currently around 1,475 units behind its agreed delivery trajectory.
The joint core strategy was adopted in 2014, setting the strategic policies for Daventry, Northampton and South Northamptonshire councils.
Slower than expected rates of completion at urban extensions being developed in the borough had contributed to the shortfall, council officers said in a report to the cabinet.
The report goes on to say that the plan "contains a housing delivery trajectory that differs from the proposed housing delivery trajectory set out in the [joint core strategy] by setting lower figures for the first five years, with higher rates of delivery in later years of the plan period".
A revised housing delivery trajectory in the Northampton Local Plan Part 2 sets an annual target of 1,518 homes in the last five years of the plan, compared to a range between 694 and 900 in the joint core strategy.
Northampton planning officers advised councillors that "the higher delivery level envisaged for the last five years of the plan period is ambitious", but said the matter could be addressed in a review of the joint core strategy which is expected to be adopted in 2022.
The plan also allocates 81 new sites for "housing and housing-led mixed use development" for a total of about 4,750 new homes.
Key site allocations in the document include 800 homes at Park Campus, 800 homes at The Green in Great Houghton, and 400 homes at Greyfriars.
The document reiterates the joint core strategy policy that developments of 15 or more dwellings will be expected to provide an affordable housing contribution of 35 per cent.
Applications for conversions to homes in multiple occupation will only be accepted where less than 10 per cent of the dwellings within a 50 metre radius of the application site are HMOs.
New developments would also be required to "demonstrate how they respond to and incorporate climate change and adaptation into the design process".
Once adopted, the document would replace saved policies from the 1997 Northampton local plan and the 2013 Northampton Central area action plan.
The Northampton Local Plan Part 2 will be submitted for examination after a six-week consultation.
In January this year, South Northamptonshire Council submitted its draft local plan for examination after five years of work and five public consultations.
Last November, Northampton councillors approved outline plans for a 3,000-home urban extension.
