A history of Hilltop Park

All the maps below have the same parcel boundaries drawn in, to create a consistent frame of reference. These boundaries are approximately the same as the actual intended boundaries of Hilltop Park and some nearby public facilities strips, as defined by an approved 2020 amendment to the Tentative Map.

Most of the maps below have been manually georeferenced - i.e. aligned to have somewhat correct geographical reference. This always involves some error, which in these maps is usually a few feet or less.

  1. 1937: The Hilltop Park area was a naturally vegetated shrubland with a cleared utility line running along the west side. My interpretation of this and other information sources is that most of the vegetation was maritime chaparral characterized by two manzanita species (Arctostaphylos tomentosa and Arctostaphylos pumila) and some small coast live oaks (Quercus agrifolia).

    In the image below, I have outlined in green the areas with taller vegetation i.e. scattered large shrubs and some small trees at the western edge (almost certainly coast live oaks). These are identified by the size of their shadows. The lighter patches are relict dune crests with relatively sparse vegetation that would be probably be characterized as coastal sage scrub. The remaining medium gray would be maritime chaparral dominated by Arctostaphylos shrubs. All of this can be reasonably confidentally inferred from detailed study of the same imagery in areas near Hilltop Park that were subsequently less impacted by Army activities as Hilltop Park was, and from the species observed at Hilltop Park in 2020 & 2021 (see below).



    Different dune-derived soils appear to determine the broader pattern of vegetation in the area of Hilltop Park. The small trees in the southwest of the above image are in a belt of what appears to be Oceano loamy sand that typically supports oak woodland. The more uniform, lower vegetation in the rest of the image are in a belt of Baywood sand that typically supports shrubs, scrub, and forbs.
     
  2. 1941: The Hilltop Park area changed drammatically between 1937 and 1941. Almost all the vegetated had been cleared down to to near ground level, and about half the park area had been graded. Five water tanks and a building had been erected on the hill. My interpretation is that the medium gray areas were not graded and thus still exhibited somewhat intact soil and living sub-surface burls from which sprouts would have been growing - for at least two shrub species (Arctostaphylos tomentosa and Adenostoma fasciculatum).

     
  3. 1956: Vegetation had grown back in the areas that were not graded prior to 1941, including many shrubs and possibly some small trees. Additional structures had been built.

     
  4. 1999: Trees and shrubs on the northwest flank of the hill. Only one water tank remaining. Several structures removed. Much of the area vegetated.


  5. 2004. Specific Plan for University Villages (previous name for The Dunes on Monterey Bay)

    The Specific Plan indicated that Hilltop Park would emphasize native vegetation ... "grown from on-site stock" ... "originating from the greater Fort Ord territory".

    Zander (consultants) mapped the Hilltop Park area as exhibiting "Maritime Chaparral" (green) and "Degraded Maritime Chaparral" (red)



    Special-status species mapped at Hilltop Park by Zander include Monterey Spineflower (Chorizanthe pungens) (Yellow) and Sandmat Manzanita (Arctostaphylos pumila) (purple).

    Casual survey of plant species by F. Watson
     


    Relevant native species missing from above list:
    - Coast silk tassel (Garrya elliptica) observed 4/11/21 just north of Hilltop Park
    - Black sage (Salvia mellifera) observed 3/1/19 in east finger of Hilltop Park
    - Peak Rushrose (Crocanthemum scoparium) observed near Marina Equestrian Center

    Eriogonum latifolium
    on the south side of the Hilltop Park area
    (also observed 2/12/20 on north side)


    Arctostaphylos sp. half cut away (later completely removed)


    Arctostaphylos tomentosa
    (or possibly Adenostoma fasciculatum, but A. fasc. tends to have conical burls)
