Local Plan Respresentations
29 January 2018 bc Local Plan Regulation 19 Representation Planning Policy Team Epping Forest District Council Civic Offices Ben Thomas 323 High Street Epping Essex CM16 4BZ 33 Margaret Street London W1G 0JD T: +44 (0) 20 7499 8644 savills.com Epping Forest District Council Submission Version Local Plan We write on behalf of Crest Nicholson in relation to the site known as the former Pickfield Nursery at Pick Hill, Waltham Abbey (SLAA Reference SR-0161). Flawed / Absent Local Plan site selection process to-date: Pickfield Nursery was submitted to EFDC in response to the Call for Sites consultation in 2008 and has subsequently been promoted through the current Local Plan process since its inception in 2012. EFDC’s July 2012 SLAA referred to Pickfield Nursery as site SR-0161 but incorrectly identified it as a duplicate site with a much larger parcel (SLAA Reference SR-0020). Representations were then submitted in October 2012 highlighting this mistake. However, despite the submission of detailed representations and subsequent regular liaison with EFDC’s officers (including a positive formal pre-application meeting), EFDC’s Site Selection evidence base published in 2016 discounted Pickfield Nursery prior to Stage 1 of the selection process, once again incorrectly considering it as a duplicate site. Pickfield Nursery was finally acknowledged as an individual site in the Local Plan evidence base in the “Sites for consideration following Regulation 18 consultation” list published in July 2017. However, at the time of writing these representations (26th January 2018, one working day before the Pre-Submission consultation deadline) an assessment of these sites has still not been undertaken and Appendix C1 of the Report on Site Selection (December 2017) has not been completed. -

The model simulates nitrogen and phosphorus processes in soils, groundwaters and river systems and can be applied in a semi-distributed manner at a range of scales. In this study, the model has been applied at field to sub-catchment to whole catchment scale to evaluate the behaviour of biosolid-derived losses of P in agricultural systems. It is shown that process-based models such as INCA, applied at a wide range of scales, reproduce field and catchment behaviour satisfactorily. The INCA model can also be used to generate generic information for risk assessment. By adjusting three key variables: biosolid application rates, the hydrological connectivity of the catchment and the initial P-status of the soils within the model, a matrix of P loss rates can be generated to evaluate the behaviour of the model and, hence, of the catchment system. -

Islington U3A Longer Walks Group
Islington U3A Longer Walks Group Walk Title Cuffley - Hertfordshire Chain Walk (see Walk No. 103 Interesting Facts below) Area Hertfordshire Type Circular Date Friday, 5th August 2016 Distance 10.7 miles (16.4km). Timing 5 hours walking time + travel and lunch stops. Say 7 hours in total. Therefore expect to be back in Islington by 5.00pm. Meeting up Meet at 9.40 latest, at the entrance of Highbury & Islington, ready to & travel catch the Great Northern 9.56 direct train to Cuffley (toward Hertford North) from Platform 4 at Highbury & Islington station. It’s about a 30 mins journey. The Freedom Pass/ 60+ Travel card area extends just to Crews Hill so you’ll need a ticket from Crews Hill to Cuffley - 1 stop. Should be able to get an Off Peak Return - £2.20. For our younger members – you’ll need a ticket to Cuffley (£7.90 cheap day return). Route From Cuffley station we turn right & immediately right again into Tolmers Rd. Follow this windy road through the back streets of Cuffley (nice houses!!) for about a kilometre along the Hertfordshire Way on to the Hertfordshire Chain Walk and into Home Wood. Through the wood turning right at the end onto ‘Newgate Street’. Although part of the Hertfordshire Chain Way unfortunately there is no pavement for about 1km on this busy main road until we get to a T junction (2.8km). Nice church here! Take the right road but immediately cut off left down a track towards Home Farm – pleasant quiet going here now. We pass a remote golf course. -
